Answer: Firstly it should be noted that, the chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. On this wise, their genomes would be more similar to each other than are the genomes of the five tree finch species. Secondly, they should be limited to the six islands that most recently emerged from the sea.

Thirdly, they should share fewer anatomical homologies with each other than they have shared with the tree finches.

Fourtly, their genomes should be more similar to each other than are the genomes of the five tree finch species.

Answer:

There are no options to this question but it can be answered by giving a general explanation. The answer is:

Because the digestive enzymes are not in direct contact with the cells that make up the walls of the alimentary canal. The walls are protected by mucuous lining.

Explanation:

Digestion of our ingested food is an important process for the effective functioning of our body system. Digestion is the process whereby food, which are usually macromolecules, are broken down into simpler molecules usable by the body. After food is taken in from the mouth (ingestion), it must be broken down by chemical and mechanical means.

The chemicals means is through digestive enzymes, which are proteinous chemical substances. The digestive system consists of the alimentary canal or digestive tract, which is a tube-like organ that forms the path for food passage. Since digestive enzymes secreted during digestion can disintegrate every macro biomolecule e.g protein, carbohydrate etc, it can also break down the molecules that make up the cells of the tract wall.

However, the digestive enzymes does not break down the cells of the canal's wall because the body system secretes mucus, which lubricates the passage of food along the canal. It also prevents the digestive enzymes from coming in contact and acting on the macromolecules that make up the cells of the walls of the alimentary canal.

See the answer below

Explanation:

At the first look, the cell was in G1 phase of the cell cycle. At the second look, the cell was in the G2 phase of the cell cycle, and at the third look, the cell was in Telophase.

At the G1 phase of the cell cycle, the cell mainly experiences growth and development. Nothing much happens except that the cell increases in volume.

At the G2 phase of the cell cycle, synthesis of DNA has taken place during the S phase and the amount of DNA present in a cell is doubled at this stage.

At the telophase stage of the cell division in the cell cycle, chromosomes have completed their migration to the poles and each pole appears like a nucleus with their individual chromosomes under the microscope. The cytoplasm is yet to divide at this stage, hence, everything still appears as a single cell.

Answer:

The primary function of the lymphatic system is defending the body against both external and internal threats.

Explanation:

The set of tissues and organs that participate in the immune response is known as the lymphatic system. Its main functions are to maintain the volume of blood and participate in the defense of the organism. It is made up of organs, vessels, nodes and lymphatic tissue. This system fulfills three basic functions: Defense: in the lymph nodes, the lymphocytes reproduce to respond to antigens; fat absorption: most of the fats are absorbed by the lymphatic system and subsequently transported to the blood and capillary exchange: it recovers substances that the blood flow has lost in the capillary exchange.

The principal function of the lymphatic system is to remove strange or damaging substances from tissues and eliminate them. The correct option is defending the body against both external and internal threats.

------------------------------

Among other functions of the lymphatic system, its principal one is the removal of damaged cells, cancer cells, and protection of the body against the virus, bacteria, and fungi that might affect it.

The lymphatic system remove these elements from the tissues for their elimination.

All these strange microorganisms and waste substances get filtrated in the lymphatic ganglia.

Ganglia are small organs located all along with the net of lymphatic vessels, that function as lymph accumulation centers.

Lymph passes through these organs and gets filtrated and purified of waste substances.

Inside each ganglion, the lymphocytes T and lymphocytes B help the organism to fight these infections.

B cells produce antibodies that impede infection propagation by trapping the microorganisms and destroying them.

Most lymphatic ganglia are grouped near the neck, underarm, and groin.

They are also grouped in the chest, abdomen, and pelvis, where they filter blood.

Answer:

The options to this question are;

A. genotype

B. adaptation

C. selective pressure

D. stabilizing pressure

The answer is B) Adaptation

Explanation:

Adaptation is the process whereby an organism becomes well suited to survive in its natural environment, which is aided by the possession of certain traits called adaptive features. For example, the fins of a fish makes it fit to survive in an aquatic environment, likewise the opposable thumbs of humans make us well suited to survive in our environment.

As stated in the question, the opposable thumb i.e. movement of the thumb independently of the other four fingers, is a characteristics of primates. This unique feature (opposable thumb) allows us to grab things, get a good grasp of tools, use tools effectively, write things, etc. All these ability due to the possession of opposable thumb increases our chances of survival. Hence, the possession of opposable thumb is regarded as an ADAPTATION

Answer:

The correct answer is - active and passive.

Explanation:

Immunity is the capability of multicellular organism to protect itself from harmful molecules that are foreign to the body such as microorganism and antigens. Immunity can be active immunity or the passive immunity.

Active immunity takes place when one's own body produces antibodies to fight against a particular disease or antigen by immune system where as passive immunity occurs when an individual receives antibodies from outside and produced outside.

Thus, the correct answer is - active and passive.

Explanation:

Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.

Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.

The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).

RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes

RRtt, Rrtt -> Red petals with short bushes

rrTt, rrTT -> pink petals and tall bushes

rrtt-> pink petals with short bushes.

Stomata and Transpiration on edmentum

Explanation:

Answer:

Explanation:

Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP—only two ATP molecules per glucose molecule during glycolysis. ... During lactic acid fermentation, pyruvate accepts electrons from NADH and is reduced to lactic acid.

The NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.

Glycolysis is defined as the metabolic pathway that converts glucose to pyruvate where the free energy released in this process is used to form the high-energy molecule adenosine triphosphate and the lesser nicotinamide adenine dinucleotide. It is a sequence of ten reactions catalyzed by enzymes.

During glycolysis , ATP and NADH are produced where lactic acid fermentation process uses NADH molecule from glycolysis molecule to convert pyruvate to lactate. During lactic acid fermentation, NADH transfers its electron to pyruvate and is oxidized to NAD+ while pyruvate is reduced to lactate.

NAD+ assisted dehydrogenation and phosphorylation of glyceraldehyde-3-phosphate (G3P) to 1,3-biphosphoglycerate (1,3-BPG) is coupled to lactate production where NADH is supplied to convert pyruvate to lactate, hence, the transfer of electrons helps the lactic acid fermentation process to repeat itself as the reduction of pyruvate to lactate regenerates NAD+ which is reused for uninterrupted operation

Thus, the NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.
