Explanation:

A man with blood type A, whose mother was type o, has a child with a woman that has type AB blood. Which blood

types are possible in their children AB, a, O.

What is ABO blood grouping ?

The blood grouping can be defined by the presence of surface antigens in the red blood cell which are  A and B. The gene present on the parent chromosome can determine the blood group.

Blood type A represents to the presence of gene A, and its genotypic expression can be A/A or A/O.

Type B blood group where genotype is represented as B/B or B/O, is due to the presence of a gene containing the B antigen.

AB blood group which is codominant- has one gene for A and another for B, with genotype A/B.

Blood type O is mainly characterized by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

Answers

Mhmmmmm I think the answer is a but I’m not for sure......

The way it gets food is a biological aspect of an organism's niche.

What is Biological niche?

The term "niche" in ecology refers to the function an organism performs within a community.

The physical and environmental requirements (such as temperature or topography) and interactions with other species that a species must tolerate make up its niche (like predation or competition).

For instance, the tiny songbird from North America known as the Kirtland's warbler which is scarce, has an extremely constrained niche. It exclusively builds its nest amid young jack pine trees (Pinus banksiana), whose seeds need regular wildfires to germinate.

Therefore, The way it gets food is a biological aspect of an organism's niche.

What height in meters must the student climb in order to reach the top of the hill?

Answers

Answer: 256 or 300 sorry if i was incorrect

Explanation:

The student must reach the top of the hill, and this is entirely dependent on the hill's elevation, which varies from one area to the next and is not constant in any particular area.

What is the significance of the hill in the ecosystem?

The hill is the highest point on Earth and plays an important role in ecosystems because it can provide a variety of different habitats for plants and animals as well as act as barriers that separate different ecosystems, such as the forest ecosystem present on one side of the hill from the grassland ecosystem present on the other side of the hill, and it is also a depositary of minerals and other resources.

Explain, in detail, the difference between a population and a community

Answers

Ecology is a branch of Biology that studies the interrelationships between organisms (plants, animals) and their environment.

The word comes from the Greek word oikos which means "house."

A Population is group of organisms of the SAME species living in the same area at the same time and sharing a common gene pool. This group is potentially able to interbreed with one another.

In ecology, the term Community refers to the populations of animals and plants that live within a specific region under similar environmental conditions. These populations of plants and animals live and interact with one another and their environment. Between Humans, the term Community generally refers to a group of people living in the same locality or sharing some common characteristics (i.e. ethnic, cultural or religious).

As a star goes through this cycle their _____ changes.

A - luminosity
B - brightness
C - all of these
D - temperature

Answers

Answer:

option C. all of these.

Explanation:

The main sequence period is when a star will experience the majority of its life. Helium is currently being created via nuclear fusion from hydrogen. Thus, option C is correct.

What is a complete cycle of a particular star?

The main sequence phase, which our Sun is in, will be entered by the star if it is large enough to fuse hydrogen atoms into helium.

The mass of a star determines its life span. The life cycle of an object decreases with increasing mass.

The amount of substance present in a star's nebula, the enormous cloud of gas and dust from which it emerged, determines the star's mass.

The temperature and pressure rise when the material compresses, just as they do during formation. The freshly created heat briefly overcomes the effect of gravity, pushing the star's outer layers outward.

Therefore, As a star goes through this cycle their luminosity, brightness, temperature changes.
