Answer:
a, c, d
Explanation:
A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures, so other structures that are like these can be considered homologous.
The pairs that have homologous structures are
a. Wing of an insect and wing of a bird.
c. The front leg of an insect and bones in the leg of a human.
d. Bones in the front leg of a dog and bones in the wing of a bat.
What are homologous organs?Homologous organs are those organs that have similar functions, but they have different structures, and they are very different organisms. Their time of evolution is also changed and different.
A wing of an insect and the wing of a bird are very different. The wing of a butterfly is made of a thin layer with veins and a bird's wings are made up of feathers, and they are bigger than a butterfly. But their functions are very similar.
So the front leg of an insect and bones in the leg of a human and bones in the front leg and wings of a bat have similar functions.
Thus, the correct options are a, c, and d.

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.

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.

The step in photosynthesis where organism capture CO2 in order to convert it into glucose
Explanation:
This step is called Carbon fixation.
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and inorganic carbon dioxide while oxygen (from the light reaction) is released.
Further Explanation:
This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This begins in the thykaloids, where pigment molecules like chlorophyll reside. The chloroplast is a membrane-bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.
Here, water is used as a reducing agent.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
In the Calvin Cycle:
During the initial stage, three molecules of ribulose bisphosphate, RuBP are reduced and carbon is fixed from an inorganic CO2 to an organic form by the enzyme RuBisCO. With every molecule of CO2 fixed, 2 molecules of 3-phosphoglyceric acid are produced. 3-PGA is a 3 carbon molecule with a phosphate attached.
This is called carbon fixation.

The Calvin Cycle or light-independent reactions of photosynthesis is where organisms capture CO2 to convert into glucose. This is accomplished using the enzyme RuBisCO and energy carried by ATP and NADPH. After three cycles, a sugar molecule G3P leaves the cycle to become part of a carbohydrate molecule.
Explanation:The step in photosynthesis where organisms capture CO2 to convert it into glucose is called the Calvin Cycle or light-independent reactions. During these reactions, an enzyme called RuBisCO fixes CO2 from the environment, combining it with an organic compound, RuBP. The resulting six-carbon compound is then broken down into two three-carbon compounds, and the energy in ATP and NADPH is used to convert these molecules into a type of sugar called G3P. After three cycles of the Calvin Cycle, one of the G3P molecules leaves to become part of a carbohydrate molecule such as glucose, while the remaining G3P molecules continue in the cycle to be formed back into RuBP to react with more CO2.

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.

What is the real story of Thanksgiving? GIVE A LOT OF DETAIL
Others pinpoint 1637 as the true origin of Thanksgiving, owing to the fact Massachusetts colony governor John Winthrop declared a day of thanks-giving to celebrate colonial soldiers who had just slaughtered 700 Pequot men, women, and children in what is now Mystic, Connecticut.
The famous first Thanksgiving took place in 1621 and involved the Pilgrims, Indians, and a feast. The Pilgrims faced challenges upon arriving in an unknown land but built trust with the indigenous people.
Explanation:The Real Story of ThanksgivingThe famous "first" Thanksgiving took place in September or October, 1621. The Pilgrims had killed a large number of ducks and geese and Massasoit arrived with about one hundred Indians who later killed five deer to add to the feast. The participants ate with their fingers and sprawled on the ground as they consumed the feast. There was no pumpkin pie or cranberry sauce, and no eating utensils except knives.
William Bradford's narrative recounts the challenges faced by the Pilgrims when they arrived in an unknown land. They faced harsh winters and dangerous storms. However, they formed a relationship with the indigenous people, including Squanto, who proved trustworthy and helpful.

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.
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.

According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembrane components, including the nucleus, endoplasmic reticulum and golgi apparatus in what would become eukaryotic cells. The evolution of endomembrane components provided for compartmentalization in eukaryotes, leading to more efficiency in cell processes. The endomembrane system includes the endoplasmic reticulum. Which statement does NOT describe the endoplasmic reticulum (ER)?
A) The ER is an extension of the nuclear envelope.
B) The ER serves as a transport network for the proteins produced in its membrane.
C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.
D) The ER serves a role in protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage
Explanation:
False: C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.
The golgi apparatus comprised of several components called cisternae, these function as different microenvironments, where further modification proteins and lipids into functional biomolecules occurs.
During protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes, the newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Within the golgi body, the proteins are tagged and parceled into lysosomes for export.
Further Explanation:
The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.
Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination.

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.
