Answer:
Bb and bb
Explanation:
The most likely genotypes of the parental generation would be Bb and bb.
If Bb and bb are crossed, such that:
Bb x bb
offspring: Bb Bb bb bb
Bb = 2/4 = 1/2 = 50%
bb = 2/4 = 1/2 = 50%
hence;
<em>1/2 or 50%% of the offspring would express the dominant condition in the form of Bb and the remaining 1/2 or 50% of the offspring will express the recessive condition in the form of bb.</em>
Answer:
<h3>Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.</h3>
<span>Homologous chromosomes exchange DNA during meiosis in a process called crossing-over. Crossing-over sometimes involves an unequal swapping of DNA. Basically one chromosome in the pair gets extra DNA.</span>
<h2>
Answer:</h2>
I believe the correct answer is D. React to stimuli from outside the body.
<h2>
Explanation:</h2>
Hormones are types of proteins that produce responses hand in hand with neurons but they are much slower and longer lasting. They can act on the same cells and in that instance they will be called autocrine hormones. Those that act on neighbouring cells are called paracrine hormones while those that act on far away cells are called endocrine hormones.
<h2>Further Explanation:</h2><h3>a. Initiate behavior and reproduction:</h3>
This is a function of hormone(s). Hormones such as testosterone can initiate both behavior of an organism and also stimulate reproduction. Testosterone causes maturation of sex features and sperms in males to initiate reproduction. Other hormones with such functions include: Estrogen and adrenaline.
<h3>b. Coordinate the production and use of energy:</h3>
Some hormones conduct this function by regulation metabolism in the body. These include: Insulin in intake of glucose for energy and glucagon in maintaining blood glucose levels. Corticosterone also responds in stress to maintain energy.
<h3>c. Maintain nutrition and metabolism:</h3>
Nutrition can be maintained by hormones such as ghrelin that stimulates appetite, insulin in intake of glucose, leptin and glucagon.
<h3>d. React to stimuli from outside the body</h3>
This is not a function of a hormone but rather the function of a neuron. Neurons have specific structures called denrites that recieve signals/stimuli from outside the body then convert them to nerve impulses that are transmitted to the brain which produces another impulse to be taken to a specific site to produce a desired response.
