Answer: The plasma membrane or cell membrane provides protection for a cell
Explanation: it also provides. Functions
The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.
What is cell membrane?The cell membrane has been defined as the structure found in the cell and the function of cell membrane is to provide protection to the cell. The cell contain several cell organelles and these are ribosomes, golgi appratus, nucleus, and the cell organelles have different functions.
When movement of molecules is takes place then it is called active transport. Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that substance are moving their own concentration gradients.
Therefore, The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.

Bees, which are known for aiding in pollination, help with which process?
A. enabling pollen to grow fruit to encase the sperm and egg
B. enabling pollen to grow a tube to transfer sperm to the egg
C.transferring pollen from the anther to the pistil
D. transferring pollen from the ovule to the ovary
Please hurry and answer for me plz!
Bees, which are known for aiding in pollination, help with transferring pollen from the anther to the pistil. The correct option is C.
What is pollination?Transferring pollen grains from a flower's male anther to its female stigma is the process of pollination.
Every living thing, including plants, strives to produce progeny for the following generation. Making seeds is one method through which plants can create progeny.
Bees are necessary for the growth of plants and flowers. They use the pollination process, in which they move microscopic pollen grains from one blossom of one sort of plant to another flower of the same kind.
The transfer of this pollen aids in the growth of the blooms which will ensures that a plant will produce full-bodied fruit and a full set of viable seeds.
Thus, the correct option is C.

12. Why are lobe-finned fish thought to be the closest relatives to tetrapods?
Answer:
Lobe-finned fish are thought to be the close relatives to tetrapods because of the fact that the fins are very flexible and potentially useful for supporting the body on land, as in lungfish and tetrapods.
Explanation:
The lobe-finned fish are thought to be the closest relatives to tetrapods because the fins are very flexible and potentially useful for supporting the body on land, same as in the lungfish and tetrapods.
What are the lobe-finned fishes?
The lob-finned fishes are called as Sarcopterygii, is a clade containing the coelacanths, lungfishes, tetrapods, and the fossil relatives as well, including the osteolepiformes and panderichthyids. These are the sister group to the ray-finned fishes called as Actinopterygii, which together forms the bony fishes called as Osteichthyes.
The basic characteristics of lobe-finned fishes such as swim bladder, lateral lines, lobed fins, enameled teeth. Tetrapods are thought to have evolved from the primitive lobe-finned fish.

In a woodland ecosystem, the number of species of microorganisms in the soil that do not
harm plants increases. How does this rise in biodiversity affect the sustainability of the
ecosystem?
A The rise in biodiversity makes the ecosystem less sustainable.
B The rise in biodiversity makes the ecosystem more sustainable.
C The rise in biodiversity does not change the sustainability of the ecosystem.
D The rise in biodiversity makes the ecosystem only temporarily less sustainable.
Answer:
I think it’s B
Explanation:
Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.
What is the rise in biodiversity in woodland ecosystem?In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.
Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.
Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.
Therefore, The rise in biodiversity makes the ecosystem more sustainable.

Why is the following molecule nonpolar and hydrophobic?
The image shows a polymer composed of a chain of 14 carbon atoms. The first carbon atom is bound to three hydrogen atoms. The next 12 carbon atoms are bound to two hydrogen atoms. The final carbon atom is bound to a carboxyl group.
The carbon and hydrogen atoms share electrons equally.
The glycerol molecule in fats contains a carboxyl group.
There are exactly three fatty acid chains present in each fat molecule.
There is an unequal distribution of hydrogen and oxygen atoms.
Answer:
a
Explanation:
The following molecule is nonpolar and hydrophobic because the carbon and hydrogen atoms share electrons equally. The correct option is A.
What are nonpolar and hydrophobic?Non-polar molecules are those which can not be dissolved in water. These molecules have ends that are not dissolved in water. Hydrophobic is a quality of the substance that is not dissolved in water or repels water.
The image shows a polymer made up of three hydrogen atoms are bonded to the initial carbon atom. Two hydrogen atoms are joined to the next 12 carbon atoms. A carboxyl group is attached to the last carbon atom.
Since charges fluctuate, a momentary dipole moment exists in a so-called nonpolar molecule.
Thus, the correct option is A, The carbon and hydrogen atoms share electrons equally.

What form of nitrogen makes up the majority (78%) of the earth’s atmosphere?
A. The deer population exceeded the carrying capacity, providing predators with a surplus of food. As the deer population
decreased, so did the carrying capacity.
B. The deer population increased as the carrying capacity stabilized. As the carrying capacity decreased, the deer population
decreased.
C. The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there
was less food available, reducing the carrying capacity.
D. As the deer population reached a maximum so did the carrying capacity. As the deer population decreased, so did the
carrying capacity until the environment stabilized and the deer population could increase again.
Answer:
C seems to be the most reasonable answer.
Explanation:
The graph depicts that in an ecosystem the deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
