The β chain of the hemoglobin protein is a single chain of amino acids and is 147 amino acids long. In humans, the gene that encodes for the β chain is located on chromosome 11. The diagrams show the DNA, RNA, and amino acid sequence of an unaffected person and a person with sickle cell anemia.image f8707eaefc0147c9bd074a15bb19c344Part A:Where does the mutation that causes this disorder occur?AThe mutation occurs on the DNA.BThe mutation occurs on the RNA.CThe mutation occurs on the ribosomes.DThe mutation occurs on the amino acid.Part B:Which BEST describes the result of this mutation?AThe entire sequence of amino acids is changed.BThe RNA strand does not code for the correct amino acids.CThe change in amino acids shortens the polypeptide sequence.DThe alternation of a single nucleotide encodes for a different amino acid.

Answers

Answer 1

Sickle cell disease is a hereditary disease seen most often among people of African ancestry. Caused by mutations in one of the genes that encode the hemoglobin protein, the disease is inherited as an autosomal recessive trait. The mutation causes the red blood cells to take on an unusual sickle shape. Individuals affected by sickle cell disease are chronically anemic and experience significant damage to their heart, lungs, and kidneys.

what are some non examples of hydroshere

Answers

Oceans, lakes, seas, and clouds are examples.

The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.

What are some non examples of hydrosphere?

It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.

Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.

Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

Shivering and vasoconstriction would be signaled to cause a: A. increase in pH. B. decrease in temperature. C. decrease in pH. D. increase in temperature.

Answers

Answer:D

Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body

Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.

What is thermoregulation?

Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.

During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.

Therefore, vasoconstriction and shivering signal the body to increase the temperature.

mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.

Answers

Answer:

mRNA destroyer concentration has a greater influence because it is destroying mRNA before  proteins can even be produced.

Explanation:

Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.

Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.

Answers

Answer:

Two eagles fight over a salmon carcass- DIRECT

All the gray foxes in a habitat prey primarily on penguins- INDIRECT

Two colonies of black ants clash over a wasp- DIRECT

Gray squirrels in an area rely on nuts for food- INDIRECT

Explanation:

Living organisms of same or different species tend to interact with one another in their natural habitat. One of those interactions is competition, which occurs when living organisms share the same limited resources or occupy the same niche in their habitat.

However, competitive interaction between organisms can either be direct or indirect. Direct interaction is that which involves a physical interaction between the organisms i.e. a confrontation. A struggling for the limited resource is evident. For example, two eagles fighting over a salmon carcass and two colonies of black ants clashing over a wasp shows the form of physical confrontation for the limited resource between the organisms involved. Hence, they are examples of direct competition.

On the other hand, indirect competition involves the competition for a limited resource without a physical confrontation or struggle. Organisms make use of the limited resource until it becomes unavailable to competitors. For example, gray foxes in a habitat that prey primarily on penguins and gray squirrels in an area relying on nuts for food shows a competition for a scarce resource without any physical interaction between them. Hence, they are examples of indirect competition.

Evaluate this statement: Gene flow increases the genetic divergence of populations. Evaluate this statement: Gene flow increases the genetic divergence of populations. This statement is true. This statement is false. Gene flow is not able to influence the genetic divergence of populations. This statement is false. Gene flow reduces the divergence of populations. This statement is false. Gene flow increases the number of genes in populations.

Answers

The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.

Explanation:

In biology and related areas, genetic divergence occurs if populations with a common ancestor develop unique traits, which are the result of genetic changes over time. On the other hand, gene flow occurs when traits including genes flow from one population to another, usually because the populations are in contact. In this context, gene flow reduces divergence because if genetic material flows between populations is less likely each population can develop unique traits, instead the populations involved will have similar traits after some time.

The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.

The following information should be considered;

In terms of biology and related areas, genetic divergence arise at the time when the populations are with a common ancestor that created unique traits, due to this there are genetic changes over time. While gene flow arise at the time when traits involved genes flow from one population to another, normally due to the populations are in contact. In this given situaton, gene flow reduces divergence since genetic material flows between populations is less likely every population can create unique traits, rather the populations involved will have similar traits.

How are the molecules in photosynthesis and cellular respiration similar? Please include descriptions of the molecules

Answers

Answer:

They are similar because they both produce energy but in two different forms.

Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.

cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.

They exhibit the same responses, but they do so in reverse. Carbon dioxide and water are converted during photosynthesis into glucose and oxygen. Carbon dioxide and water are produced during respiration in exchange for glucose and oxygen.

What similarity in photosynthesis and cellular respiration?

Energy transformations from one form to another are a part of both respiration and photosynthesis through a sequence of metabolic reactions.

The reactions that are carried out by both processes—which both use and produce ATP—are carried out on membranes and are managed by enzymes.

Light energy is converted by photosynthesis into chemical energy that is stored in glucose, which is then released by cellular respiration to create ATP, the life-sustaining compound.

Therefore, They are similar because they both produce energy, but in two different forms.

Tree-dwelling primates have prehensile tails for gripping branches. Tree-dwelling opossums also have prehensile tails.  Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues.    Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not.  Marsupial mammals throughout Australia show a wide diversity of forms that reflect the habitats in which they live. Hawaiian honeycreepers, with their elongated, nectar-sipping bills, all evolved from a finch-like ancestor.

Answer and Explanation:

Tree-dwelling primates have prehensile tails for gripping branches.  Considering recent ancestors, the prehensile tail trait can be considered as a convergence example that occurred among different groups. But we can also think about it as a common descent if we consider the farthest primates ancestor. Although still controversial, Plesidiapsi might be considered a common ancestor of primates, that evolved from a ree-dwelling mammal with a long tail. It is believed that this animal used to live in trees.   Tree-dwelling opossums also have prehensile tails.   Convergence. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Convergence. These are two groups that are very separated from each other, and they developed different traits according to their needs separately. Some of the species of these two groups adapted to feed on the same plant so they needed to develop the same characteristic to obtain nectar.Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not.   Common descent .
