If the blockage is removed from the blood vessel, what will happen to blood flow after removal?
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.
What is the function of; 1.plumule,
2.embryo,
3.hilum,
4.microphone
5.and cotyledon?
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.

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?
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.

(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.
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.

To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same amount of salt to each container and stirs until the salt is completely dissolved. He places Container 1 in a cool place in the house and Container 2 outside in the sunlight. After two hours, he tests the salinity of water in each container. What should the student MOST LIKELY conclude, and why?
Answer:
The correct answer would be - container 2 will have less salinity than container 1.
Explanation:
The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.
We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1

propose a definition for digestion using the following terms; nutrients, food, liquids, solids, transformation and digestive juices
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.

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
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.
I hope this helps!

Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.
Which statement best describes the importance of wisdom teeth to human evolution?
A. They are vestigial structures that once performed an important function for human ancestors.
B.They are evidence that humans have never evolved.
C. They are vestigial structures that never performed a necessary function for human
ancestors.
D.They are evidence that humans cannot evolve.
Answer:
A
Explanation:
There's a reason they grew there in the first place. The Caveman mouth was much larger than our modern mouths.
The statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.
What do you mean by Evolution?Evolution may be defined as the change in the characteristics of a species over several generations and relies on the process of natural selection.
Wisdom teeth are evolved in humans because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose.
Therefore, the statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.

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.To learn more about phenotypes, selection, directional selection and population here,
