The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?

A. bbTT X BbTt

B. BBtt X BBTT

C. bbtt X bbtt

D. BbTt X BbTt

Answers

The genotypes would be bbTT X BbTt

Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.

Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)

The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTTThe genotype of a tree that is heterozygous for both trait would be BbTtThus, the cross would be bbTT x BbTt

Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other

Answers

Answer:

Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

11 Apply If you have a cold that causes congestion in your sinuses, how
might that affect your sense of smell? Support your claim with evidence.

Answers

Answer:

If there's a blockage of this channel, like when you have a stuffy nose due to the flu or a cold, odors can't get to the sensory cells the smells stimulate. This results in you losing a lot of your ability to taste the flavor of food. In this manner, your senses of taste and smell work closely together.

Answer:

It will affect your smell because you can have a lot of snot in your nose and your nose will be stopped up with all that stuff.

For each number before "-1," if it is positive and odd, do the following: Consider that a man is watching a picture of a Black Horse. He receives an external stimulus from input channel. Man gains some information about the picture from external environment and stores it in the memory. Once the initial information is gained, it is compared with the memory and then stores it. Finally upon perceiving and storing the information in memory Man says that the picture contains Black horse.Based on the information-processing model, cognition is conceptualized as a series of processing stages where perceptual, cognitive, motor processors are organized in relation to one another. You are required to identify and elaborate that which cognitive processes i.e. Perceptual system, Cognitive system, and motor system are involved when man interacts with the picture and also that which input channel is responsible in taking information to the brain.
