What can happen when a community becomes isolated from the rest of its species for many generations?
a) Competition between individuals will decrease.
b)The community will grow more slowly.
c)A new species can form.
d)There would be no effect on the community.
Answer:
C) A new species can form.
Explanation:
This is the concept of genetic drift, where a species being isolated gets an unnatural change in the gene pool, and thus can evolve differently.
Name three factors that can result in a decrease in the size of a population
Answer:
birth rate,death rate, immigration and emigration
In his journey to the Galapagos Islands, Charles Darwin was amazed by the variation in the characteristics of plants and animals he encountered. In any habitat, food can be limited and the types of foods available may vary. One year, there was no rain on these islands. Many plants failed to bloom and produced no new seeds. This left mostly large, tough seeds for the finches to eat. Describe one change in beak characteristics that would most likely occur in the finch population after many generations if this change in seed size became permanent.

A seed, known as "pinhão", is the great evolutionary novelty that is present in Gymnosperms plants. Choose the correct affirmative sentence related to seeds.
Hi. Unfortunately, you didn't show the answer options, which makes it impossible for me to answer your question. However, I'm going to give you some general information about seeds that can help you find the right answer. Hope this helps you.
Seeds are structures responsible for plant proliferation. They exist only in gymnosperms and angiosperms and are absent in bryophytes and pteridophytes. All seeds are formed in the ovary of flowers as a result of the plant fertilization process.
All seeds are formed by three structures known as integument, nutrient and embryo. The embryo is what gives rise to another plant, which will grow after the seed is planted and germinates. Nutrients will be responsible for meeting the needs of the new plant during the beginning of its development. The integument, in turn, has the function of protecting the embryo.

How do scientists think Prokaryotic Cells contributed to changing Earth’s atmosphere to include more oxygen?
Explanation:
Then, about 2.5 billion years ago, oxygen started getting added to the atmosphere by photosynthetic cyanobacteria. “Oxygen is produced as a waste product of photosynthesis. ... “The production and burial of plant matter over long periods causes oxygen levels to rise,” explains Poulsen

ow do cells use food to make energy and maintain homeostasis
Answer:
Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). ... They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.
Explanation:
There are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. ... This system uses the energy stored in ATP to pump potassium into the cell and sodium out of the cell.
Identify ALL of the functions of proteins. Structure and is found in tendons, bones, and ligaments. Communication and works as chemical messengers such as hormones. Defense as in antibodies. Transportation and are embedded in the cell membrane to allow substances to move across the cell membrane. Enzymes that lower the activation energy of a reaction. Contraction to allow muscle and cell contraction/movement. Eicosanoid such as in regulation of blood pressure or inflammation. Steroids such as cholesterol. Glycogen for energy storage in muscles.
Answer:
Structure and is found in tendons, bones, and ligaments.
Communication and works as chemical messengers such as hormones.
Defense as in antibodies.
Transportation and are embedded in the cell membrane to allow substances to move across the cell membrane.
Enzymes that lower the activation energy of a reaction.
Contraction to allow muscle and cell contraction/movement.
Explanation:
Proteins serve many functions in living organisms.
Structure: The most abundant protein in mammals is collagen and is found throughout the body. In a major component of connective tissue such as skin, ligaments, and tendons providing strength and elasticity to these tissues. It is found also mineralized in bones and teeth.
Proteins function as hormones which are chemical messengers that mediate many cellular responses in the body. For example, the hormone insulin is a protein.
Proteins functions in the body's immune system as antibodies which recognize and initiate immune responses against diseases. The immunoglobulin such as immunoglobulin A and G are proteins.
Proteins serves as transporters to move substances across the cell memebrane. Some are found as peripheral or integral membrane proteins. Examples of transport proteins are the glucose transporters, Glut-1, Glut-2 and Glut-4 transporters.
Enzymes are proteins which catalyse the chemical reactions tanking place in an organisms. Various enzymes in the body include the hydrolases, the ligands, the leases, etc.
Contraction of the actin filaments of the muscle which are proteins, allow muscle and cell contraction bringing about movement.
A Note on the other options.
Eicosanoids are lipid molecules which serve various functions such as in regulation of blood pressure or inflammation.
Steroids such as cholesterol are lipid-derived molecules.
Glycogen for energy storage in muscles is a storage form of glucose, a carbohydrate.

Explain how the cell division of cancer cells like these are misregulated. Identify genetic and other changes that might have caused these cells to escape normal cell cycle regulation
Answer:
Due to non-functioning of protein.
Explanation:
The cell division of cancer cells like these are misregulated because they can't be control by the proteins that is responsible for the control cell division. The cancer cells can multiply without any growth control factors, or growth-stimulating protein signals that control its growth. There are some proteins that is responsible for control of cell division but due to mutation that protein of substance stop working and the cancer cell grows uncontrollable.

how does the nervous system communicate with other parts of the body?
The central nervous system (CNS) is composed of the brain and the spinal cord. The central nervous system communicates with the rest of the body by sending messages from the brain through the nerves that branch off of your spine.

The central nervous system communicates with the rest of the body by sending messages from the brain through the nerves that branch off of your spine. You are able to move your body
human picks up bacteria on his or her hands. The bacteria do not cause disease but do feed on the human's dead skin cells. This is an example of
Answer:
The correct answer is - Commensalism
Explanation:
Commensalism is a symbiont relationship in which there is a relationship between two organisms in which one gets benefits and the other organism is unaffected.
Human skin has many commensal bacteria that fed on dead cells of the skin. Here humans are hosts that do not get harm and bacteria rely on them for survival.
