The genotype is the set of genes in our DNA which is responsible for a particular trait. Thephenotype is the physical expression, or characteristics, of that trait. For example, two organisms that have even the minutest difference in their genes are said to have different genotypes.
Answer:
2)Homologous Structures Humans Share With Animals
A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures. ... This structure serves as evidence of having a common ancestor, one that would have had a tail. All mammals share the homologous structure of the vertebrae in common.
3)WHERE IS THE DIAGRAM
Explanation:
Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
Answer:
All other things being equal the size of a population will decrease if the death rates exceeds the birthrates...
Explanation:
We have attached a figure that shows the diagram of the given equation.
We need to find how many angles are alternate exterior angles with angle 5?
We know that an exterior angle is the angle that is made outside of the shape and an alternate angle is the angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
