Answer:
Galapagos finches have various beak sizes that make foraging for food more successful.
Explanation:
Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.
Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.
Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.

Explain the relationship between surface area
and cell size and why it is important for cell sizes
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
Explanation:
The relationship between surface area and cell size is important to the cell because it determines how materials are exchanged in the cell, such as which materials go out and which come in, based on this ratio.
What is the significance of the cell surface area?The relationship between surface area and cell size is important because cells exchange materials with their surroundings based on it, for example, when the cell size increases, the volume of the cell increases more than the surface area, which decreases the ratio of surface area to volume and allows less substance to exchange through the cell, and vice versa.
Hence, the relationship between surface area and cell size is important to the cell because it determines how materials are exchanged in the cell, such as which materials go out and which come in, based on this ratio.

Which clade of organisms is characterized as containing many extremophilic microbes?
А
archaea
B
eukaryotes
С
fungi
D
plants
Answer:
The answer is A.) Archaea.
The clade of organisms characterized as containing many extremophilic microbes is archea. The correct option is A.
What are archaea?A class of microbes known as archaea is related to yet evolutionary separate from bacteria. Numerous archaea have been discovered to survive in harsh conditions, such as high pressures, salt concentrations, or temperatures.
Extremophiles are the name given to these kinds of creatures. Single-celled microbes called archaea have a similar structure to bacteria. They make up the third domain of life and are unique from bacteria and eukaryotes in terms of evolution. Archaea are obligate anaerobes that exist in low-oxygen settings (e.g., water, soil).
Therefore, the correct option is A, archaea regarding the extremophile microbes.

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibit PS I but do not affect PS II (case 2).
Which of the following results is expected?
A)in case 1, only PS I completely loses function; in case 2, no proton gradient is produced.
B)In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced.
C)In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced.
D)In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
What is an ion pump??

Answer:b. tissue damage in the brain due to a shortage of blood supply
Explanation:
Cerebrovascular disease is a group of conditions, diseases, and disorders that affect the blood vessels and prevents blood supply to the brain.
If there is a blockage, malformation, or blood clot that prevents the brain cells from getting enough oxygen, it can lead to brain damage.
Causes of Cerebrovascular disease includes atherosclerosis i.e narrow arteries, thrombosis, blood clot in the artery of the brain,blood clot in a vein of the brain.
Example of Cerebrovascular diseases include stroke, transient ischemic attack (TIA), aneurysm, and vascular malformation.

what is the equation for photosynthesis? why is it important for the plants to have both cellular respiration and photosynthesis(think about the equations)
Answer:
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship.
