B multicellular
C producer
D consumer
NEED ANSWERS ASAP!!
Answers
All organisms in a food web can be described as consumers, as this term encompasses all levels from primary to quaternary consumers, unlike producers which only refer to the base of the food web.
Explanation:The original question asks to describe all of the organisms shown in a food web. To answer this question accurately, we must consider the characteristics shared by each organism within the web, spanning from producers to quaternary consumers.
The correct answer is D. consumer, as this term includes all organisms that rely on consuming other organisms for energy, encompassing primary, secondary, tertiary, and quaternary consumers. Producers, which are typically photosynthetic organisms like plants or phytoplankton, form the basis of food webs by producing organic compounds from inorganic sources.
However, the question asks for a description that applies to all organisms within the web, making consumers the correct choice since they make up the majority of any food web, relying on other organisms for energy and nutrients.

Answer:
In biology it refers to observed changes in organisms, to their descent from a common ancestor, and at a technical level to a change in gene frequency over time; it can also refer to explanatory theories (such as Charles Darwin's theory of natural selection) which explain the mechanisms of evolution. Natural selection
There are two major components to the theory. The first is the mechanism of natural selection, which was proposed independently by Charles Darwin and Alfred Russell Wallace in 1858.
In the same way artificial selection occurs when breeders choose seeds or studs that will improve their stock in the next generation, natural selection is the process of sorting living things according to how well adapted they are to their environment.
In the case of artificial selection, humans choose which traits are desirable. In the case of natural selection, traits that increase the likelihood of survival and reproduction will become more common within a population or species over time.
In the past, natural selection has been misrepresented by calling it the survival of the fittest. This statement oversimplifies the mechanism by making it sound like a tautology: the survival of those who survive.
The truth is that individuals never survive. What survives is the process for making another individual, and this resides in genes found in populations.
Natural selection has more to do with differential reproduction than survival, and what it selects are the genes that code for desirable traits or characteristics. The interaction of individuals with their environment provides a mechanism for sorting out which traits (not which individuals) will be passed on to the next generation.
Nature of inheritance
The second major component to the theory is the nature of inheritance, which follows the insights made by Gregor Mendel in 1865 and has advanced considerably since then due to our understanding of genes, DNA and the molecular processes of life.
When natural selection was first formulated by Darwin, the nature of inheritance was not understood. Our current understanding of inheritance is very sophisticated and includes the precise mechanisms for passing genes on to the next generation, how genes are modified by mutation and how they are shared among sexual species.
If we know enough about a gene and its various forms, it is possible to accurately predict the change in the frequency of those genes over time using mathematical formulae from population and evolutionary genetics theory.
This alteration of gene frequencies is subtle and does not, at first glance, seem worthy of being called evolution. But it is precisely these small changes at the genetic level that lead to large changes in the organisms that carry them.
The sorting of genes affects the fate of populations: populations drift apart and become species, and species diverge to create whole groups of plants or animals that dominate the landscape for millions of years.
The intricate details of cellular processes are responsible for the glorious and majestic diversity of life on our planet.
The theory of evolution includes large changes over vast periods of time and tiny changes made when one cell divides into two.
These processes form a continuum that is the history of life on Earth

organelle:
cytoplasm
golgi complex
lysosome
rough endoplasmic reticulum
smooth endoplasmic reticulum
Answers
Nuclear membrane- The nuclear membrane keeps DNA inside the nuclear and protects it from materials in the cytoplasm.
Nucleolus- The nucleolus makes ribosomal submits from proteins and ribosomal RNA. (Makes proteins in the cell)
Animal Cells:
Cytoplasm- Cytoplasm is responsible for giving the cell its shape and keeping the organelles in their place.
Golgi complex- The Golgi complex processes and bundles macromolecules.
Nuclear membrane- The nuclear membrane is a double membrane layer that separates the contents of the nucleus from the rest of the cell.
Nucleolus-The nucleolus plays a vital role in making proteins in the cell.
The Golgi complex is involved in modifying and packaging proteins and lipids in both plant and animal cells. The nuclear membrane regulates substance flow in and out of the nucleus, and the nucleolus assembles ribosomes in plant cells. In animal cells, the cytoplasm provides medium for reactions, lysosomes digest waste, RER synthesizes and modifies proteins, and SER synthesizes lipids and stores calcium ions.
Explanation:The functions of the organelles you've inquired about are crucial for the life of the cell. In a plant cell, the Golgi complex modifies, sorts, and packages proteins and lipids for storage or transport out of the cell. The nuclear membrane, also known as the nuclear envelope, encloses the nucleus, providing a barrier that regulates the flow of substances into and out of the nucleus. The nucleolus within the nucleus is responsible for ribosome assembly, which are then transported out to the cytoplasm for protein synthesis.
In an animal cell, cytoplasm is the gel-like substance enclosed within the cell membrane, providing a medium for chemical reactions and helping to support the cell's structure. The golgi complex functions similarly to that in plant cells. Lysosomes contain digestive enzymes that break down waste materials and cellular debris. The rough endoplasmic reticulum (RER) is studded with ribosomes and is the site for protein synthesis and modification, while the smooth endoplasmic reticulum (SER) is involved in the synthesis of lipids, detoxification, and calcium ion storage.

Answers
Final answer:
Fungi were once classified as plants, but scientists observed a key characteristic that required reclassification. The cell walls of fungi are made of chitin instead of cellulose, and fungi absorb nutrients from other organisms.
Explanation:
Fungi were once classified as plants due to their similarities with plants such as immobility, having cell walls, and growing in soil. However, scientists observed a key characteristic that required reclassification: the cell walls of fungi are made of chitin instead of cellulose, which is found in plant cell walls. Additionally, fungi absorb nutrients from other organisms, while plants can make their own food through photosynthesis.can the behavior of a material of substance be considered a physical property
Answers
Answer:
Physical properties are those attributes of a material that can be observed and/or measured without changing the composition or identity of that material. Examples of such properties include color, smell, freezing point, melting point, viscosity, opacity. density, solubility, polarity, texture and many others.
Now if the behavior of a material is inherent to that material, and is an attribute that can be observed or measured without effecting any chemical change in that material, then it may very well be considered a physical property of that material.
For example if a particular element or material melts at 40 degrees centigrade, this is a behavior of that element and is considered a physical attribute.

D. Why do different regions have different organisms. Various organisms are varying in different environment based on their adaptations.
Charles Darwin is best known for what?Charles Darwin is best known for attempting to answer the question of why different regions have different organisms, which is also known as the theory of evolution by natural selection.
He observed that different species of organisms had unique adaptations that helped them survive in their respective environments. Darwin proposed that over time, these adaptations could lead to the development of new species as they evolved to better suit their environment.
His work challenged the prevailing belief of his time that species were fixed and unchanging, and his theory of evolution is now widely accepted as a fundamental principle of biology.
Charles Darwin attempted to answer the question of why different regions have different organisms, which led to his development of the theory of evolution by natural selection.
Therefore, he made various theories in order to produce various consequences in order to establish the phylogenetic traits and theories along with the establishment of the creatures.

Answers
Temperature and amount of available water.
Abiotic: a non-living factors that affect organisms and their ecosystem. Can be a physical or chemical part.
Temperature and water as we know, are not living (biotic) components.
The most important abiotic factor of a forest ecosystem is temperature and the amount of available water as these directly affect the resources and climate. Thus option C is correct.
What are biotic and abiotic factors?The forest ecosystem is made up of two components that decide the characteristics of the forest. The tropical rainforest has a constant temperature and high amount of precipitation.
one is abiotic which is the non-living like air, temperature, and rain and the other is biotic factors which are the living parts like animals, and birds, plants, and decomposers.
Temperature and water control the habitat of animals and these are abiotic factors and have a direct effect on the ecosystem of forests. So option C is correct.

How are pollen and egg cells different than most other plant cells?
Answers
Answer:
Fertilization, which is the union of sperm and egg, occurs deep within the flower after pollination. When a pollen grain lands on the stigma, it generates a tiny tube tipped with sperm. The tube fits into a conduit called a style in the female pistil.
Explanation:
Pollen grains and egg cells differ from most plant cells by being specialized haploid gametophytes with features that ensure successful fertilization and seed formation for plant reproduction.
Pollen grains and egg cells, which represent the male and female gametophytes respectively, differ from most other plant cells in several ways. Pollen grains are male gametophytes containing a few cells and are specialized for transport to female reproductive organs. This is possible due to features like a protective coat that prevents desiccation, and, in some cases, structures such as air sacs that facilitate their movement towards the ovule. The whole structure is adapted to ensure successful fertilization without dependence on water. Egg cells are found within the female gametophyte, which also contains additional cell types like the synergids and antipodal cells.
The key characteristic of pollen and egg cells is their ploidy level: they are haploid (1n), containing a single set of chromosomes, unlike the diploid (2n) cells found in most of the plant body (sporophyte generation). This difference is crucial for sexual reproduction, as the fusion of a pollen grain’s sperm cell with an egg cell will result in a diploid zygote, from which a new sporophyte will develop. Seed formation then follows, encapsulating the zygote to provide protection, nourishment, and a mechanism for dormancy until growth conditions are optimal.
What is the current theory about the formation of the solar system?
I need a answer ASAP!!! My test is TIMED
A big bang occurred in the solar system as a result of a fusion reaction. All the matter in the solar system that had been clumped together was shattered and sent flying. As new pieces of matter connected, all the celestial bodies of the solar system were formed.
The solar system began as a cloud of dust and gas that condensed, forming a bulging middle and an outer disk. The bulging middle of the cloud became the sun, and the rest of the dust and gas formed the planets, orbiting the sun in the same plane.
About 14 billion years ago, several supernova events scattered all the known elements throughout the galaxy. The magnetic elements were attracted to each other and formed the early celestial bodies that eventually became the planets of the solar system.
The area of the universe that was to become the solar system went through a period of vast expansion as a result of rapid radioactive decay that left behind clouds of dust and gases. The excess clouds and gases were used to form the various parts of the solar system.
