Answer:

A) Chromosomes are made of DNA

C) Alleles are the different forms of a gene that can exist

D) Chromosomes contain genes that control the inheritance of traits.

Explanation:

Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene  (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.

A boy blows up a balloon and knots the end he leaves it on the kitchen counter. His little sister finds it and takes it outside
Diano4ka-milaya [45]

Answer:

The balloon will expand or explode (with enough time)

Explanation:

Charles law states that the volume of a fixed gas is directly proportional to the temperature and pressure. The higher the temperature, the higher the pressure. This will raise the volume, causing the balloon to expand at the very least.

A pink unicorn is crossed with a blue unicorn and all of the offspring are lilac, caused by the presence of both pink and blue h
siniylev [52]

Answer:

The correct answer is codominant.

Explanation:

A phenomenon in which two heterozygous alleles get expressed completely in the offspring produced is termed as codominance, and the trait produced is termed as a codominant trait. In codominance, both the alleles show their presence, that is, none of them is considered dominant, and like incomplete dominance, the alleles do not get mixed up.  

For example, in the given case, the crossing between a pink unicorn and a blue unicorn produces an offspring, which is demonstrating both pink and blue color fur. This shows that the phenomenon of codominance is taking place and the produced trait is an illustration of codominant trait, as the produced offspring is having both pink and blue color hair.

Deamination occurs mostly in the brain. T/F
ki77a [65]

The answer is false.

Deamination is the process (reaction) in which an amine group is removed from a molecule of amino acid. The enzymes that are involved in this reaction are called deaminases. Deamination can be used for energy(break down of amino acids), when there is too much protein intake. Amine group is converted to ammonia that is then converted to urea or uric acid in the urea cycle and at the end excreted through the urine.

In the human body, deamination occurs mostly in the liver (e.g. urea cycle), but also in the kidneys (deamination of glutamate).

Which of the following cell structures would you expect to be most important in the growth of bacteria in the hypotonic surround
Naddika [18.5K]

Answer:

2. cell wall

Explanation:

The Cell wall is a thick layer made up of peptidoglycan that structurally supports and protects the cell. The cell wall is located just outside the semi permeable membrane. It give rigidity to the cell.

The cell wall also serves as a sieve or filter that allows or prevents the movement of molecule in or out of the semi permeable membrane.

An hypotonic solution is a solution that has a higher quantity of water when compared the quantity of solute dissolved in the water and this causes the solution to have a lower osmotic potential.

When a bacteria is growing in an hypotonic surrounding environment, there is a large amount of water present outside the cell. The cell wall of the bacteria serves as barrier and prevents the flow of water into the cell and this would prevent the cell wall of the bacteria from bursting open due to the rigidity of the cell wall.

Any bacteria that lacks a cell wall and is place in an hypotonic surrounding environment would swell and eventually burst open due the movement of water from hypotonic surrounding environment into the bacteria.
