Answer:

C

Explanation:

The brother has different alleles for the blood type gene than his sister does.  Blood type is inherited from parents like many other traits that can be displayed on a punnet square.  Depending on what the parents blood type alleles were, the brother and sister could have different blood types.  

A different number of chromosomes doesn't lead to different blood types, so D is wrong.  And A is incorrect because the number genes also does not affect blood type.  And I think the blood type genes are on the same chromosome, so B is wrong.  C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.

DochEvi [55]

Answer:

To answer this question you have to think, "What am I really" to answer that you are your brain. When you say "am I thinking whenever I have a desire to" your brain is the "I." You think when your brain wants you to think. It rules everything that happens. It creates thoughts and commands all parts of the body.

Briefly describe asexual reproduction in plants
AysviL [449]

Asexual reproduction requires only one parent. Since there is only one parent, there is no exchanging of genetic information, and the offspring are clones of the parent. Asexual reproduction in plants can occur in a variety of forms, including budding, vegetative propagation, and fragmentation. Let's discuss these reproduction types.

Have you ever found an old potato hidden in the back of a cabinet in your kitchen? If a potato sits around for a long time, it will have many small growths, commonly referred to as 'eyes'. Each of these sprouts can be cut from the potato and planted. They will grow into a clone of the original plant that produced the potato. This is a classic example of budding.

For an example of vegetative propagation, let's look at the strawberry plant. If you plant strawberries, you will notice that a row of plants will quickly spread into a large mass of plants. This is because they do a type of vegetative propagation by producing runners. Strawberry plants send out horizontal stems known as stolons. These stems will work their way into the ground in places and form roots, and eventually a new plant will grow.

A third type of asexual reproduction in plants is called fragmentation. This type of asexual reproduction is often used by nurseries and greenhouses to produce plants quickly. For many plants, a clone can be created by breaking off a portion of the stem and placing it in soil or water, depending on the plant. This also happens naturally when small parts of a plant fall off onto the soil and begin to grow into a new plant. An example of fragmentation occurs in liverwort plants, whose small stems or leaves are often broken off by animals or wind and then grow into clones of the parent plant when they land in the soil. I hope this helps
