The Amish populations in the United States began with relatively few individuals and have not recruited many newcomers to the population. Today, these Amish populations exhibit a much higher incidence of polydactyly (possessing extra digits) than other American populations. Which mechanism of evolution is likely responsible for this phenomenon

Answers

Answer 1

Answer: The founder effect

Explanation: The high incidence of polydactyl prevalent among the Amish population could be attributed to the a case of genetic drift called the founder effect. The founder effect occurs when a small population consisting of few people separate from a much large population, just like the Amish population separating from the larger American community. Due to the few composition or small size of the population, the genetic impact or influence on members of the population is usually higher than the effect on the larger population and leading to more rapid spread. The relatively small individuals which make up the Amish population compared to the larger American community is the reason why polydactyl hmis prevent within them and since theere are no newcomers, the trend will likely continue.

If the study on the relationship between W. bancrofti and Wolbachia is correct, then combined with the results of the trials, significant numbers of microfilariae do not survive in circulation beyond what time period

Answers

Answer:

6 months

Explanation:

First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.

1. The Hawaiian Islands are examples of islands that formed over a hotspot. Based on this information, which of the following processes formed the Hawaiian Islands? (2 points) Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled. Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks. One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface. Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.

Answers

Answer:

The correct answer is -  Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.

Explanation:

The Hawaiian Islands are the chain of eight major islands situated in U.S. of Hawaii. These are formed over a hot spot. About 75 million years ago such hotspot took place in the center of the Pacific Plate.

There are hot spot due to the volconic activity and in the moving over the tectonic plate of a subduction zone. Volcanic activity and overriding of plates that cause rising magma by melting the moving down plates whice leads to volcanic arcs formation. The magma that rose gradually cooled down and become solid over the time. It is an example of a large seamount and island chain created by hot-spot volcanism.

Thus, The correct answer is - Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.

Plants respond to changes in their environment. They detect gravity, light, touch, and seasonal changes, and respond to these stimuli in many ways.

B) The genes that regulate plant responses can be expressed in different ways. C) The genes that regulate plant responses can mutate to adjust to environmental changes. D) Phenotypes control the genotypes of individuals, determining plant responses.

Answers

Answer:

B)

Explanation:

Plants have the ability to detect the changes in their environment and respond accordingly. Plants' responses to stimuli is due to the genes that regulate plant responses can be expressed in different ways.

Genes code for hormones and support transport of hormonal synthesis in plants. Plants hormone such as auxin promotes different changes in plant growth in response to light, gravity, touch or seasonal changes and the auxin respond due to transport inhibitor response 2 gene.

Hence, the correct answer is "B".

Answers

Answer:

 glycolysis; dihydroxyacetone phosphate

When fats are used as an energy source, the glycerol portion enters the glycolysis when it has been converted to dihydroxyacetone phosphate. Thus, the correct option is A.

What is the Glycolysis?

Glycolysis may be defined as the process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen.

In order to obtain energy from fats, triglycerides must be broken down into fatty acids and glycerol through hydrolysis. The fatty acids enter to Krebs cycle and are converted into acetyl CoA.

While the glycerol portion enters into glycolysis and is converted into dihydroxyacetone phosphate.

Therefore, the correct option for this question is A.

The answer is C, because the rate of enzyme activity is at its highest when the temperature is 45°C. I hope this helps!

The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.

What are the factors affecting enzyme activity ?

The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes

The rate also increases with increased enzyme concentration up to the saturation point

Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.

The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by  forming a loose complex and inhibits the activity of enzymes.

Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.

water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.

how do i explain assimilation of glucose, amino acid and lipid?

Answers

Assimilation simply means the ways by which some of the food we eat and are absorbed by the body are being converted to new protoplasm or used to provide new energy for the body.

ASSIMILATION OF GLUCOSE

The hepatic portal vein transports absorbed sugars to the liver,the excess glucose is then converted to glycogen by insulin.When needed by the body,the liver in-turn converts this glycogen to glucose so that they can be moved to the cells,from there glucose is transported to every other parts of the body so that they can provide the cells with needed energy,during cell respiration,glucose is oxidized to release energy to be used for vital activities.

ASSIMILATION OF AMINO ACIDS.

Amino acids which are end products of protein passes through the liver to all parts of the body.

When amino acids are excess in the body,they will be deaminated in the liver to form urea, amino acids aren't stored,they are used to make proteins,repair worn out cells, aids growth, formation of enzymes and hormones and conversion into new protoplasm.

ASSIMILATION OF LIPIDS

Lipids which are end products of fats and oils are transported by the lymphatic capillaries or lacteal.

When lymph comes together with fat, chyle is formed,this chyle will further be discharged into the bloodstream and will be carried by the blood.

Fats are used to alternate source of energy for the body and as well form new protoplasm like the cell membrane.

When fats are in excess,they are stored in the adipose tissue which are found around the heart, kidneys, beneath the skin,and mesenteries that binds the intestines.

Significant amounts of phosphorus are found in all locations on Earth except the..

Answers

Answer:

Atmosphere

Explanation:

Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.

The atmospheric temperature and pressure are incapable of forming phosphorus compounds, Phosphorus has not been found in the atmosphere.

Phosphorus has been the recycled in the atmosphere within the biosphere, lithosphere, and hydrosphere. In the nature, the phosphorus has been present in the sedimentary rocks, with the absorption by plants and animals.

The phosphorus cycle has been consisted of the weathering, absorption by plants and animals and return to the lithosphere with the decomposition. Since the atmospheric temperature and pressure are incapable of forming phosphorus compounds, Phosphorus has not been found in the atmosphere.

Sebastian wants to make ball-and-stick models of the four macromolecules. He has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen Which molecule could he make that consists of long chains of red and black colored balls? carbohydrates lipids nucleic acids proteins

Answers

Answer:

lipids

Explanation:

There are four major biological macromolecules in living systems viz: carbohydrate, proteins, lipids and nucleic acids. These macromolecules play a significant role in the optimal functioning of every living organism. Like every other polymer, these macromolecules are made up of simpler units called monomers that defines their chemical structure. In turn, the monomers consists of chains of chemical elements held together.

According to the question, Sebastian has colored balls that represents the elements contained by each of these macromolecules. The colored balls and the elements they represent are as follows: Red: hydrogen, Black: carbon, Purple: oxygen, and Green: nitrogen.

Lipids are structurally made up of fatty acids and glycerol, which are long chains of carbon and hydrogen elements with a relatively small percentage of oxygen in the structure. An example is palmitic acid, which has a structural formula: CH3(CH2)14COOH

Hence, Sebastian could make a LIPID macromolecule, which consists of long chains of red (hydrogen) and black (carbon) balls since lipids are mostly made up of carbon and hydrogen elements in their structure.

Carbohydrates are composed of more percentage of oxygen in their structure. Hence, a long chain of only red (hydrogen) and black (carbon) balls cannot make them. Proteins and nucleic acids are made up of additional nitrogen and phosphorus elements in their structure.
