Predicting the genotype<span> of </span>offspring<span>. There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.</span>
Serotonin and n<span>orepinephrine.
Serotonin decreases appetite by activating </span>5-HT2C receptors<span> on dopamine-producing cells which will cause dopamine release to stop. Dopamine is responsible for the increase of appetite, therefore, serotonin decreases appetite.
Norepinephrine by increasing the production of glucose it also causes the body to feel satiety and, therefore, decreases the appetite.</span>
D.
Selective breeding
In selective breeding, the desired genes from one organism are combined with genes of another organism, resulting in a new combination of genes.
<span>The selective breeding is quite voluntary and is not necessarily natural or congenital. It is the act of how people or individuals can choose traits in the gene pool of their choice to produce their desired or goal organism in the process. This trait is influenced in the host of the specific sperm and egg cell which makes up the chromosomes. </span>
Answer:
Prokaryotic, and eukaryotic cells share basically four common features:
1) A plasma membrane which is known as outer covering membrane it helps to separate the interior part of the cell from its surrounding.
2) Cytoplasm which is consisted of gel like region inside the cell where other parts of the cell are found.
3) Genetic material of the cell which is known as DNA.
4) Ribosomes, which helps in protein synthesis.
Answe: Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
