Answers

Answer:

Large solid food particles are breakdown into small simper food molecules.

Explanation:

Digestion is the process in which large solid food particles are breakdown into small simper food molecules so that they can be absorbed by the body and added to the blood plasma. These simpler molecules are absorbed by the cells to generate energy in the form of ATP. This transformation from solid food particles into simpler molecule through mechanical and chemical digestion. Mechanical digestion starts from the mouth in which the sold big particles are changed into smaller pieces with the help of teeth while on the other hand, the chemical digestion occurs through digestive juices that helps in break down.

Two bodies of water that are approximately the same size depth and latitude are found to have a large difference in the number of species inhabiting them what is likely the contributing island biogeography factor resulting in a difference in the number of species found in each body of water?

Answers

Answer:

Due to the presence of suitable environment.

Explanation:

Suitable environmental conditions are responsible for the presence of large amount of species in water bodies because suitable environmental conditions provides necessary materials for the growth and survival of organisms. The marine environment that have sufficient amount of food, space, optimum temperature, pH and salt concentrations so in this environment more number of species are present due to increase in population as compared to those ecosystem having harsh environmental conditions.

What is the function of; 1.plumule,
2.embryo,
3.hilum,
4.microphone
5.and cotyledon?​

Answers

Answer:

1=Function of Plumule (shoot tip): The plumule is the part of the embryo that develops into the shoot bearing the leaves of the plant. The plumule gives rise to aerial shoots. The function of cotyledon: They store reserve food material or serve as photosynthetic organs in young seedlings.

2=An embryo is the early stage of development of a multicellular organism. In general, in organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs.

3=. In botany, a hilum (pronounced /ˈhaɪləm/) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). ... The adjectival form hilar denotes the presence of such a mark, and can be used as a distinguishing characteristic of a seed or spore........!!!!!

4=A microphone is the device responsible for transferring sound as it travels through the air, and converting it into electrical impulses that can be amplified by PA systems, or recorded by either analog or digital recorders.

5= Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.

If the blockage is removed from the blood vessel, what will happen to blood flow after removal?

Answers

Answer:

Normally, blood flows freely through your blood vessels, arteries, and veins. Your arteries carry blood with oxygen and nutrients to your body. Yours veins carry waste products back to the heart. In some cases, the blood thickens and clumps to form a blood clot in one of these vessels. This can block the blood flow. When blood flow is blocked, nearby tissues can be damaged.During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.

ANSWER ASAP!! Which type of selection occurs when a population experiences a shift in diversity toward the larger organisms?
1. stabilizing selection
2. directional selection
3. disruptive selection
4. adaptive selection

Answers

Answer:

2

Explanation:

edge 2021

The type of selection that occurs when a population experiences a shift in diversity toward the larger organisms is a directional selection.

What is a selection?It is a phenomenon by which some organisms have better advantage at surviving than the others of the same species.These organisms prevail and are reproductively more successful than the others.What is a directional selection?It is the type of selection in which an extreme phenotype is selected and the rest are at a disadvantage."The allele frequency is shifted in the direction of that phenotype.What is a disruptive selection?

It is the type of selection in which both the extreme phenotypes are favored than the others.

What is a stabilizing selection?It is the opposite of directional selection.In this the mean phenotype is selected and the extreme phenotypes are not.

(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.

Answers

Answer:

The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.

Explanation:

Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria

If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.

When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

Explanation:

An earthquake , a forest fire , a hurricane  and a volcanic eruption are the events that is responsible for the suitable conditions for primary succession because all the population of animals and vegetation are removed from an area and the new type of organisms is start to living in that new environment. These new organism has the ability to survive that environmental conditions. These events completely removed the population in the environment and provides conditions for primary succession.

Which of the following explains why geological events occur?

a The lower mantle is solid rock
b The crust is the same thickness throughout
c The crust is a single layer throughout
d The lower mantle is hotter

Answers

The lower mantle is hotter

Answer:

Hey there,

The answer is A.

This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.

They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.

It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.

It is not C as the mantle is semi molten not solid.

And it’s not D because it’s not a single layer but multiple layers.

So A is the answer.
