The species that are least closely related according to evolutionists would be the pair with the highest number of amino acid differences between them, that pair would be Species 1&2, last potion.

The change in heritable traits of biological populations over successive generations is referred to as evolution. Evolutionary processes generate diversity at all levels of biological organization. The last universal ancestor is the common ancestor of all life on Earth.

Because a protein's amino acid sequence is determined by its DNA sequence, a gene shared by two closely related organisms should have similar, if not identical, amino acid sequences. This is because closely related species most likely diverged relatively recently in the evolutionary timeline.

Answer:

Insect Pollination

The arctic fox is an important species in the case study ecosystem, and its presence or absence has a major impact on vegetation. The nutrients that seabirds add to the soil help in the growth of vegetation.

When keystone species are present, arctic foxes regulate seabird populations to keep the ecosystem in balance. In turn, this guarantees that the soil receives essential nutrients and that the vegetation is strong and prosperous.

Seabird populations may have increased in the absence of the arctic fox, which is a keystone species and consumes much of the local grasses or plants. This can ultimately result in a decline in vegetation growth, altering the ecosystem, and impacting other organisms that depend on vegetation for survival.

There can be several reasons for differences in enzyme activity, including temperature, pH, enzyme concentration, substrate concentration, and the presence of inhibitors or activators.

Enzymes are biological catalysts that accelerate chemical reactions in the body. The rate of enzyme activity can be affected by various factors, such as temperature and pH. Each enzyme has an optimal temperature and pH range at which it functions best. Deviations from this range can cause the enzyme to denature or lose its shape, leading to a decrease in activity.

Changes in enzyme concentration can also affect activity. An increase in enzyme concentration generally leads to an increase in activity, while a decrease in concentration leads to a decrease in activity. The rate of enzyme activity can also be affected by substrate concentration.

A scatter plot is used to display a correlation between two continuous variables, as shown in the given problem. A line of best fit is a straight line that passes through most of the data points in a scatter plot, indicating the direction and strength of the relationship between the two variables.

In order to determine the line of best fit in a scatter plot, one needs to draw a line that best represents the overall pattern of the data points. To illustrate, one might consider the following three graphs:In the first graph, the line of best fit is relatively flat, indicating a weak correlation between the two variables. This means that weight does not increase or decrease in direct proportion to height, but rather varies more independently.In the second graph, the line of best fit is more diagonal, indicating a stronger correlation between height and weight.

This means that as height increases, weight also tends to increase, although the relationship is not necessarily linear.In the third graph, the line of best fit is steep, indicating a very strong correlation between the two variables. This means that as height increases, weight tends to increase at a faster rate.

The answer to the given question would depend on the slope of the line of best fit in the scatter plot provided. However, it is not possible to determine this without the scatter plot itself. In this case, the line of best fit would be a good predictor of weight given height.

Answer: The question is incomplete and the options are not given but here are the options gotten from another websites.

A. Narrow part.

B. Wide part

C. The flow rate are the same in both part.

The correct option is C.

The flow rate are the same in both part.

Explanation:

The flow rate are the same in both because when there is partial blockage at the artery wall, the blood flow speed will reduce or stop, therefore the blockage will be a barrier or hindrance to free blood flow and therefore, both the narrow part and wide part will receive the same level of blood flow because of the blockage and this blockage result in restricted blood flow which in one way or the other hinder oxygen supply to the heart. The blockage deposits can cause a thickened artery wall and when blood flow is restricted it causes chest pain and if it stop it can cause heart attack. Blockage deposits can be as a result of artery wall damage.

Answer: it is 300

Explanation:

Answer:

the objects have very large masses or an object in circular orbit. This has motion but its always being to pulled to earth by gravity.

Greater gravitational forces will be used to attract heavier things, since the gravitational force is directly proportional to the mass of both interacting objects. Two objects are attracted to one another by gravity as their respective masses increase. Thus, option B is correct.

The gravitational pull between two objects changes inversely with their squared distance and directly with their large masses.

As a result, the gravitational force between the two items would decrease to one-fourth of its initial strength when the large masses of both objects are halved without affecting their distance.

Therefore, The objects are either in a circular orbit or have extremely  large masses. Although something is moving, gravity is always bringing it dangerously close to the ground.

The flexibility of spider silk determined by the structure of its molecules is quite strong.

The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.

The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.

The substance that is an organic molecule made during photosynthesis is glucose.

During photosynthesis, plants and some other organisms convert sunlight, carbon dioxide, and water into glucose, which is an organic molecule. Here's a step-by-step breakdown of the process:

1. Sunlight is absorbed by pigments, such as chlorophyll, present in the chloroplasts of plant cells.

2. The absorbed sunlight energy is used to initiate a series of chemical reactions in the chloroplasts.

3. Carbon dioxide is obtained from the atmosphere and enters the plant through tiny openings called stomata, primarily located on the undersides of leaves.

4. Inside the chloroplasts, carbon dioxide undergoes a series of reactions collectively known as the Calvin cycle or the dark reactions.

5. During the Calvin cycle, energy from sunlight is used to convert carbon dioxide molecules into a three-carbon sugar molecule called glyceraldehyde-3-phosphate (G3P).

6. Some of the G3P molecules are then converted into glucose, a six-carbon sugar molecule, through additional enzymatic reactions.

7. Glucose serves as the primary energy source for plants, which they use for various metabolic processes and growth.

8. Excess glucose can also be converted into other organic molecules, such as starch or cellulose, for storage or structural purposes.

In summary, glucose is the organic molecule made during photosynthesis, and it plays a crucial role in providing energy and building blocks for plant growth and development.

Option(B) Ureter is the correct option.

The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.

The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.

The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.

The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.

In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.
