Answer:
MULTICELLULAR-means many cells whereas UNICELLULAR means one cell
Explanation:
Multicellular organisms have specialized cells forming tissues and organs, while unicellular organisms consist of a single cell.
Multicellular organisms are composed of multiple cells with different shapes and specific organization, forming tissues and organs. On the other hand, unicellular organisms consist of a single cell, like bacteria and amoebae, and do not have specialized tissues or organs.
Development in multicellular organisms involves producing various cell types and organizing them into tissues and organs, requiring a complex developmental process. In contrast, unicellular organisms do not have this level of cell differentiation.
1. By examining the fin of a primitive fish, scientists
have found similarities in bone structure to that of
modern day reptiles, birds, and mammals. What
type of evidence does this describe?
The question discusses the concept of homologous structures, which are similarities in anatomy across different species pointing to a common ancestor. This evidence supports the theory of evolution through common descent, indicating that species evolve divergently from a shared origin.
Explanation:By examining the fin of a primitive fish and noticing similarities in bone structure to modern day reptiles, birds, and mammals, scientists are observing homologous structures. Homologous structures are examples of an anatomical similarity that results from organisms sharing a common ancestor. This type of evidence points towards the evolutionary theory that suggests modern species share a common ancestor. Over time, this ancestral lineage diverged through evolutionary changes, leading to the variety of species we see today. These structures have evolved in different ways to suit the needs of different species but retain an underlying structural similarity that hints at their shared origins.
Homologous structures are not limited to the skeletal system; they can also include other anatomical features that demonstrate a common ancestry. The presence of these structures across different species provides a compelling argument for the concept of evolution through common descent, showcasing how evolutionary pressures and environmental changes have sculpted various forms from an ancestral blueprint.
4. ***Which of the following particles represents an ion?
a 14 protons, 14 neutrons, and 14 electrons
b. 9 protons, 9 neutrons, and 10 electrons
e 19 pretons, 21 neutrons, and 19 electrons
d. 1 proton, 3 neutrons, and 1 electron
Hey there!
An ion is any atom with an electric charge. This can be negative or positive.
To see which one of these is an ion, first see what causes an electric charge. Positive charges are caused by protons. One proton = one positive. Negative charges are caused by electrons. One electron = one negative. Thus, when the number of protons and electrons are equal, this makes it so there is no overall charge. Thus, to make an ion, the number of protons and electrons must be unequal.
When we look at the answer choice, we can see that the number of protons and electrons are equal for every single choice except for choice b. Thus, your answer is b.
Hope this helps!
This is rivalry or competition between individuals of different species within a specific habitat.
Answer:
Interspecific competition
Explanation:
Competition between individuals of different species is known as interspecific competition. In such competition for a limited resource, organisms with suitable structural and behavioural adaptations survive while others without such adaptations may die out or migrate. Competition is severe if the ecological niches of competing organisms are close.
The ribosome of the bacterium E. coli includes the ribosomal protein L4 (rpl4). The rpl4 gene carries the instructions for making rpl4 protein. Which of the following arguments provides support for the claim that E. coli has a common ancestor with all other organisms?
Answer:
Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.
Explanation:
Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.
The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.
a student studying primary succesion should foucus on which of these communities
Answer:
A student studying primary succesion should focus on Granite rock.
Explanation:
Primary succession includes the presence of rock and the other elements that break down rocks to form soil and other stuffs.As the student is focusing on the study of the primary succession the main topic would be the granite rock. The other options relate to the later stage of succession like the Mesquite grassland comes after the primary succession stage. Granite rock is the intrusive igneous rock that looks like a granular structure.the curved paths of global winds and surface currents are caused by?
The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in.
Final answer:
The curvature of global winds and surface currents is mainly due to the Coriolis effect, while unequal heating of Earth's surface and the shape of ocean basins also play a role.
Explanation:
The curved paths of global winds and surface currents are primarily caused by the Coriolis effect, which is due to the rotation of the Earth. This effect causes moving air and water to turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating curved paths. In addition to the Coriolis effect, unequal heating of Earth's surface by the sun (more solar radiation at the equator than at the poles) and the shape of ocean basins also contribute to the patterns of surface currents. Together, these factors create distinct wind belts and cause the moving air and water to flow in specific directions.

Hydro-international article: Benthos, Inc.
Benthos was founded by Samuel O. Raymond.
He created an innovative company in marine technology which has positively impacted the field for over four decades.
It manufactures a variety of oceanographic equipment, including flotation devices; hydrophones for locating mining sites, tracking boats, and research for marine biology; and modems, which are used to communicate information wirelessly underwater.
For much of the company's lifetime, it supplied underwater equipment to the military, the government, and for research.
Smithsonian Magazine: 14 fun facts about marine bristle worms
Polychaete worms are a diverse class of animals with at least 10,000 species.
They are characterized by a head and a tail, and a pair of bristled "legs", called parapodia, for each segment of their body. They are typically bioluminescent, meaning they have the natural ability to glow.
Due to their effective adaptation, they can live in any marine habitat (including coral reefs, hydrothermal vents, or simply out in the open ocean) and have survived the five mass extinctions since 500 million years ago.
National Ocean Service: What is a bivalve mollusk?
Bivalves are mollusks with a two-part hinged shell to cover a soft invertebrate. They breathe and eat using gills.
Their organ, the mantle, produces calcium carbonate which causes the shell to grow with the organism.
They have important roles of being prey for predators, filtering water, and acting as a habitat in aquatic ecosystems.
These mollusks can live in any of the five oceans, whether it be the frozen Arctic or the hydrothermal vents in the Pacific.
There are over 9000 species.
Marine Education Society of Australasia: Echinoderms
Echinoderms are characterized by radial symmetry, having multiple of five arms, a calcium carbonate shell, and an outer layer of skin that maintains the skeleton.
They are found on the sea floor and include starfish, sea cucumbers and sea urchins.
They have the ability to hunt prey larger than their mouths due to their ability to eat from their stomachs. They detect food through a senstitivty to chemicals, although they lack any brains.
There are over 7000 species.
Thoughtco: Sea Squirts
Sea Squirts, scientifically tunicates or ascidans, are a class in the animal kingdom with over 2000 species.
They were given this name for their ability to contract and squirt water.
They do this using the inhalant and exhalant siphons, which are also used for eating and excreting waste.
They live in subtidal locations while attached to shells, rocks, piers and boat hulls.
Sea Squirts may live in colonies or individually. Colonies are created when they reproduce by budding, or when a new animal grows off of the original.
National Geographic.com: Sea Anemones
Sea anemones are an invertebrate which have stinging and venom-filled tentacles, called polyps, to hunt passing fish.
They tentacles surround a central mouth and inject a paralyzing substance into its prey, before guiding them into the mouth.
Apart from hunting, they also eat leftovers from clownfish, who are immune to the anemone because they are covered with a mucus and live within the polyps.
They live attached to rocks on the seafloor and coral reefs, usually in tropical waters.
There are over 1000 species.
Conclusions or Summary:
The marine technology company Benthos led to the discovery or further information about these animals because it provided equipment to researchers.
All of these organisms are animals and diverse with thousands of species in each of these common names.
They are adaptive and can generally live and thrive in a variety of habitats, whether the difference be in surface material or climate.

(D. provide the enzymes needed for plant growth
After a volcanic eruption, the order of succession in the re-population of the area is Lichens → grasses → shrubs → trees.
What is the Ecological succession?The process of change in the species structure of an ecological community over time is known as ecological succession. Lichens are considered a self-sustained miniature ecosystem of themselves.They can grow themselves in any condition.
After lichen, grasses can be grown and, then shrubs and trees. This is referred to as the treeless regions found in the Arctic region and it is characterized by the presence of a windy and cold climatic system which doesn't favor the growth of tall plants.
Perma frost on the other hand is referred to as a permanently frozen layer on or under Earth's surface and it establishment of tree due to the soil not being suited for a long and deep pattern of root system.
Therefore, After a volcanic eruption, the order of succession in the re-population of the area is Lichens → grasses → shrubs → trees.

Lichens and mosses are pioneer species that help make the environment suitable for subsequent plant growth by breaking down rock into soil and enriching the soil with nutrients, such as nitrogen, through their symbiotic relationships with cyanobacteria.
These organisms are known for being the first to colonize areas of bare rock or soil after an event that leaves an area barren. Lichens, which are symbiotic associations between a fungus and a photosynthetic partner like algae or cyanobacteria, are capable of leaching nutrients from substrates and helping in soil formation. Similarly, mosses establish relationships with nitrogen-fixing cyanobacteria, contributing nitrogen to the soil, making it more hospitable for subsequent plant growth including grasses and shrubs.

Evolution is sometimes a controversial topic. Write a paragraph (minimum 5 short paragraphs) including the following:
What is your opinion about evolution?
Do you think there should be a controversy?
Do you think alternatives to evolution should be taught in schools?
Why or why not?
Evolution is sometimes a controversial:
Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.
I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.
I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.
Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
Evolution is a process supported by scientific evidence, and controversies arise when religious or ideological beliefs clash with scientific explanations. Alternatives to evolution, such as creationism or intelligent design, should not be taught in science classrooms as they lack scientific basis.
Explanation:Evolution:
Evolution is the process by which species develop and change over time through natural selection. It is supported by a vast amount of scientific evidence, including fossil records, genetic studies, and observations of evolutionary changes in real-time. While there are still some controversies surrounding certain aspects of evolution, the theory is widely accepted and taught in schools as the main explanation for the diversity of life on Earth.
Controversy:
There should not be a controversy about the theory of evolution itself because it is based on objective scientific evidence. However, debates and controversies can arise when religious or ideological beliefs clash with scientific explanations. It is important to distinguish between scientific controversies, which are resolved through evidence-based discussions, and controversies that arise from personal or faith-based beliefs, which cannot be proven or disproven through scientific methods.
Alternatives in Schools:
Alternatives to evolution, such as creationism or intelligent design, should not be taught in science classrooms as they are not scientifically rigorous or supported by empirical evidence. Science education aims to teach students about factual knowledge and the scientific method, and alternative theories that lack scientific basis do not meet these criteria. However, it is worth mentioning that topics related to religion and philosophy can be addressed in appropriate courses or discussions that focus on these subjects.

You're reading from the journal of a European explorer from the early 1600s. In one passage, the explorer describes sitting on the Atlantic Ocean with little wind. He describes the area as being quite far north of the equator and having high pressure.
In which type of global wind was this explorer sailing?
doldrums
horse latitudes
jet stream
polar easterlies
Answer:
horse latitudes (B) hope this helps
Answer:
Option B
Explanation:
Doldrums are located some 5 degrees away from north while horse latitude is located some thirty degrees away from north latitude and by same degrees from the southern hemisphere. Polar eastariles are cold winds blowing across the Polar Regions and jet stream is fast blowing winds.
Horse latitude is silent winds and the region has high pressure and very little precipitation.

Which of these factors does NOT play a significant role in cell differentiation?
Answer:
Certain segments of DNA will be lost in the translation process, rendering certain genes obsolete in particular cells.
Explanation:
DNA, RNA, and environmental factors all play significant roles in cell differentiation. While DNA is identical in every cell, evert cell does not express the same genes. In different cells, some genes are turned "on" while others are suppressed or turned "off." The combination of genes expressed allows for cells to differentiate.
(Copied from USATESTPREP)
Maturation does not play a significant role in cell differentiation; rather, the process is governed by the selective expression of genes through transcription factors.
Explanation:The factor that does not play a significant role in cell differentiation is maturation. Cell differentiation is a process where cells become specialized in their structure and function. This process is mainly influenced by the expression of specific genes through the action of transcription factors, which either promote or hinder the transcription of these genes. Factors such as differentiation, specialization, and modification are critical to this process, as they relate to how cells become distinct from one another and undertake specific roles within an organism. However, maturation, while part of the development process of an organism, does not directly dictate or influence the differentiation of cells in the same way that gene expression and transcription factors do.

In what possible scenario would the female birds evolve to having the singing trait? (5 points)
Explanation:
I'm sure the scenario was that the "male songbird " was faced with more females than males.. so the FM's would search 4 the depleted males. (like the status of m/FM in Austrailia).
Answer:
A possible scenario in which the female birds evolve to having the singing trait would be if the number of predators of that bird species depleted in the area. In this particular species of bird, the females have evolved to be non-singing for the sole purpose of avoiding detection by predators. So if the predators are no longer a valid threat, then there is no longer any use for the non-singing trait.

Each phospholipid is made up of?
Answer:
Each phospholipid is made up of 2 fatty acid molecules, a phosphate group and a molecule of glycerol.
The fatty acid molecules are formed by long chains of carbon and hydrogen.The phosphate group is formed by an atom of the element phosphors which is attached to four oxygen atoms. The fatty acids make the tail and are hydrophobic. The phosphate group makes the head.
Due to their structure, phospholipids are best suited to make the cell membrane in organisms.
Final answer:
Each phospholipid molecule is composed of a hydrophilic head, which includes a phosphate group attached to a glycerol molecule, and two hydrophobic tails, which are the long hydrocarbon chains of fatty acids. These molecules are essential for forming the cell membrane's phospholipid bilayer, crucial for the cell's structure and function.
Explanation:
Composition of Phospholipids
Each phospholipid is a crucial component of cell membranes, consisting of a polar, phosphate-containing hydrophilic head and two nonpolar, long-chain hydrophobic tails. The hydrophilic head group is attached to a glycerol molecule. This configuration is essential for the formation of the cell membrane's phospholipid bilayer, where the hydrophilic heads face outward towards the aqueous environment, and the hydrophobic tails face inward, away from water. The glycerol backbone serves as the anchor for both the hydrophilic head, which includes the phosphate group, and the hydrophobic tails, which are composed of either saturated or unsaturated fatty acids. These fatty acid chains are long hydrocarbon chains that contribute to the phospholipid's insolubility in water.

What happens as more and more carbon leaves other reservoirs and enters the atmosphere?
Question 4 options:
Rocks turn into shells.
Plants run out of air.
The atmosphere heats up.
Volcanoes become less active.
Answer:
The atmosphere heats up as more and more carbon leaves other reservoirs and enters the atmosphere,
Explanation:
During carbon cycle the carbon from the reservoirs is added into the atmosphere in the form of gases.As more and more carbon leaves the reservoirs, it is converted to gases such as carbon dioxide, carbon monoxide etc.Being a green house gas, carbon dioxide traps the heat that re-radiates from the Earths surface and keeps the atmosphere warm.So, when more carbon leaves the reservoir and enters the atmosphere ; the level of carbon dioxide increases and more heat is trapped.This results in heating up of the Earth's atmosphere.
