Which would be an example of disruptive natural selection?

Biology
1 answer:
expeople1 [14]2 years ago
5 0

An example of disruptive natural selection is the presence of more light-colored moths in rural areas and to more dark-colored moths in industrial areas but FEWER medium-colored moths in either location. Thus, the correct option is A.

<h3>What do you mean by Natural selection?</h3>

Natural selection may be defined as the approach through which populations of living organisms acclimate and change.

Disruptive natural selection occurs when environmental conditions changes in two different ways or in two different locations.

Therefore, the correct option for this question is A.

The binding of oxygen to hemoglobin differs from the oxygen binding behavior of myoglobin because
aalyn [17]

The binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin because oxygen binding to hemoglobin is cooperative.

<h3>Hemoglobin - oxygen binding</h3>

Hemoglobin is the oxygen carrying protein of the blood that is located at the red blood cells. They have high affinity for oxygen.

Myoglobin is found in the muscle cells and they are contain haem proteins which they used to transport and store oxygen in the muscles.

Hemoglobin and myoglobin are two types of globin proteins that serve as oxygen-binding proteins, but binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin.

This is because binding of oxygen by hemoglobin is cooperative. This means that as hemoglobin binds successive oxygens, the oxygen affinity of the subunits increases. This is opposite for myoglobin.

1. do you think erythropoietin levels in athletes at low altitude are lower, higher, or the same after training at a high altitu
den301095 [7]

1. Erythropoietin will be higher at low   altitude. Erythropoietin or EPO level will be higher because of the raised blood oxygen training but its lasting period will depend on the training content as here it is only 2 months.

About high erythropoietin:

Among the objectives of altitude training is to improve athletes' sea-level endurance performance by raising blood oxygen carrying capacity. The attainment of improved haematological variables is mostly due to the augmented erythropoietin (EPO) production in hypoxia. The duration of exposure and degree of hypoxia affect the level of the erythropoietin EPO rise and the rate of erythropoiesis acceleration. The haematological response to altitude training may also be influenced by a wide range of additional factors.

2. 100 ml of blood contain 27.8 mL of oxygen. This can be said as it has been shown that a healthy person typically possesses 20 grammes of haemoglobin in every 100 millilitres of blood.

Procedure:

=20∗1.39

=27.8mL

Amount of oxygen found in 11 grams of hemoglobin is equal to 1.39 milliliters of oxygen.

Thus, the total amount of oxygen in milliliters would be equal to product of total weight of hemoglobin and the total amount of oxygen in ml in one gram of hemoglobin.

3. Athletes training at high altitude have more oxygen molecules. They have an advantage as a result of having more red blood

Why so:

Higher elevations have thinner air, which has less oxygen molecules per volume of air. The body therefore makes more red blood cells when athletes workout at these high elevations. For up to 20 days, these additional blood cells remain in the body. Also as a result of having more red blood cells, their blood can carry more oxygen. When they compete at lower elevations, their muscles naturally get a boost from more oxygen.

How do you know if a reaction is endothermic?
Helen [10]

Answer:

If the products are at a higher energy level than the reactants, the reaction must have absorbed energy. If you have to heat the reactants to keep the reaction going or if it cools down during the process, the reaction is endothermic.
