Blood type doesn't fall into the category of dominant/recessive genes exactly; rather it combines this with the properties of incomplete dominance. Ignoring the Rh factor, there are 3 alleles for blood type, I^a,I^b, and i. You will be type A if you have I^a I^a or I^a i and type B if you have I^b I^b or I^b i. You can also get type AB by having the combination I^a I^b or be type O if you have i i. If you need to use dominant/recessive, you can say the A and B allele are dominant over the O allele and codominant with one another.
Answer:
Among others, two adaptations might be
- Avoiding corporal heat loss
- Increasing oxygen absorption
Explanation:
Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:
- Avoiding heat loss. Temperature tends to be very low at highs, so, to <u>avoid heat loss,</u> animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate.
- Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown.
- Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements.
- Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
One reason biodiversity is such an important aspect of sustainability is that it provides vital ecosystem services through the interactions among species and keeps any population from growing too large (option A).
<h3>What is biodiversity?</h3>
Biodiversity refers to the number and variety of species of plant and animal life within a region.
Sustainability is the means of configuring civilization and human activity so that society, its members and its economies are able to meet their needs and express their greatest potential in the present without compromising the ability of future generations to do the same.
Biodiversity helps to ensure sustainability because it provides vital ecosystem services through the interactions among species and keeps any population from growing too large.

During mitosis, chromosomes move to the middle of the spindle during metaphase. Mitosis is a type of cell division in which the parent cell divides into two daughter cells with each daughter cell receiving the same number of chromosomes as the parent cell. Mitosis has the following phases: prophase, metaphase, anaphase and telophase.
