Answer:
The blood flow would be delayed, since the amount of red blood cells increases the total density of blood volume, which is why the greater the quantity of blood, the thicker the blood will be.
This, as a consequence, could cause thickening of the blood, thus becoming denser, affecting the continuous laminar flow inside the blood vessels, this means that the flow is not unidirectional, but when it is delayed, it produces a kind of micro whirlpools that hinder healing, circulation, oxygenation and stimulate the appearance of deep and superficial clots or thrombosis.
Explanation:
It is important to clarify that the polycythemia which we are talking about is very excessive, very noticeable, unlike the physiological polycythemia that the body does when faced with an increase in height and a decrease in partial pressure of oxygen.
This is important for you to know, because the body when we climb a mountain or climb, or the partial pressures of oxygen decrease in the atmosphere, takes as a compensation mechanism the increase of red blood cells to maintain the oxygenation of the body, but this being PHYSIOLOGICAL is not excessive.
Polycythemia due to genetic failure such as the one we are writing now is a pathology because we are facing an excessive EXCESS of red blood cells, where phenomena of jaundice and hemolysis can also occur due to the great imbalance that is generated in the entire body

Explanation:
A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.
A multicellular organism typically begins as a single cell, and then many cell divisions occur to generate the cells of the adult organism. However, these cells are not identical to the original cell, and they are not identical to one another.
What is the most significant cause of cell differentiation in a multicellular organism?
A.
differences in the number of chromosomes per cell
B.
differences in the genetic code used by different cells
C.
differences in the DNA that is copied and distributed among the cells
D.
differences in gene regulation and gene expression among the cells
Answer:
D
Explanation:
Difference in cell regulation and cell expression. This is embedded in chromosomes which is the blue print of the organism. The chromosomes is like the house plan when you building a house.
The most significant cause of cell differentiation in a multicellular organism is: D. differences in gene regulation and gene expression among the cells.
What is cell differentiation?Cell differentiation can be defined as a process through which a young, unspecialized cell undergoes various changes in gene expression, so as to become a specialized that is more specific in terms of function.
In a multicellular organism, which is an organism with multiple cells, the most significant cause of cell differentiation is as a result of differences in gene regulation and gene expression among its cells.

Explanation:
The pattern of natural selection where BOTH of the extreme versions of a trait are more advantageous than the average, so a population evolves in both directions away from the average.
Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.

Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. What would happen to an ecosystem if this process was compromised?
A.
The population of green plants in the ecosystem would increase.
B.
There would be more energy available to consumers in the ecosystem.
C.
The soil quality of the ecosystem would dramatically improve.
D.
The carrying capacity of the ecosystem would be limited.
Answer: D
Explanation:
Since the Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. They end up playing a vital role in the ecosystem, if this were to be compromised nothing good would come form it Disease, competition, predator-prey interaction, resource use and the number of populations in an ecosystem all affect carrying capacity. If Earthworms, small insects, and microorganisms couldn't break down the the dead material and return it to the soil, then surely the carrying capacity would be drastically effected.

Tracey was learning about structural organization in animals. What level of structural
organization BEST describes an egg?
A. a cell
B. a tissue
C. a system
D. an organ
Answer:
A
Explanation:
Egg cell
The level of structural organization which best describes an egg is: A. a cell.
A cell can be defined as the fundamental (basic) structural, functional, and smallest unit of life, that is typically found in all living organisms such as animals.
The structure of an egg is similar to those of cells found in living organism, which are structurally layered with various cell organelles.
An egg shell is selectively permeable because it acts as an outer membrane just like in living cells to prevent unwanted materials from going into the egg.
In conclusion, the level of structural organization in animals cells can best be describe by using an egg.

Explanation:
BY USING FOREST WISELY;
It was learnt that people are cutting trees at an worrying rate.This problem is disturbing because ;
1)Those trees are responsible for releasing of oxygen and they made up at least a quarter of the world population.
2) Those trees of the world make up of portion land species by more than forth or fifth portion.
There are also economic implications as a result of trees been cut down, when there is no availability bot trees , it could result to situation whereby there would be scarce of resources for industries as well as
hike price of paper in market, regardless of this trees are needed for manufacturing of important materials such as usage in making houses and others developments or growth
Therefore, all the afformentioned economic concern result in economics delay scientists' first attempts.
COMMUNITY CONSERVATION;
It was learnt that there is to the forest that those gorilla habitated, those human being that reside in those region reside there so they can practice their farming because their is available land there. They also reside there because of housing.
These gorillas were affected as a result of the destruction made to their habitat as well as the activities of the poachers that hunt them for production of the and skin.
There are adverse effect of the obliteration of the gorilla from on the society, it can result to having reduction in tourism in country such as
Uganda as well as Rwanda, as result of this the means of livelihood of people in that part could be affected because there would be Reduction in profit making. Hence the reason behind the increase in number gorillas in the region, because they know they know that those gorilla influence the number of tourist that comes there and the revenue that is generated through this tourism.
The article 'By using Forest Wisely' can be summarised as:
People are cutting trees at the wrong rate and trees play a crucial role in an ecosystem. The trees produce oxygen and they made up at least a quarter of the world population.The trees occupy the fourth or fifth portion of the land organisms.In the absence of trees, the ecosystem will fail and the organisms dependent on them will eventually die. The resources available from the trees will be scarce and the factories and industries that are dependent on trees will no longer be available. Trees are required for manufacturing important materials.The article 'Community Conservation' can be summarised as:
In the article, it was mentioned that the human populace urbanized the land region where gorillas were habituating. The humans occupied the space to practice farming and make houses. The population of the gorillas was disturbed and diminished. The hunting of gorillas by poachers was also reduced. The people of Uganda and Rwanda also suffered reduction tourism and conservation of wildlife. Gorillas influence the number of tourists, therefore, the destruction of their habitats led to a reduction in profit-making.Therefore, all the mentioned economic concerns result in economics delaying scientists' first attempts.
