When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period. Most normal cells can leav

e G0 phase and reenter the cell cycle at G1 phase before entering S phase. Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following? A) Fall to complete S phase B) Mutate during G1 phase C) Repeat the cell cycle continuously D) Die after completing mitosis

The appropriate answer for this one is C. Cancer cells divide uncontrollably and therefore the cell cycle would be continuously divide. To add, t<span>here is a term known as terminally differentiated cells. These cells that never enter the cell cycle again, meaning they stay in G0 and never divide. However, some cells can be triggered to depart G0 and re-enter G1, which permits them to divide again.</span>

Match the following terms and definitions. 1. alternative form for a specific gene (either dominant or recessive) hybrid 2. can
galben [10]

The answers would be:

1. Allele - alternative form for a specific gene (either dominant or recessive)

2. Dominant - can prevent the allele from being expressed in a pair of genes

3. Genotype - the genes present in an organism

4. Heterozygous - it is a pair of non-identical genes that influence a trait in different ways.

5. Homozygous - a pair of genes that are identical in the way they influence a trait.

6. Hybrid - offspring from a cross between parents; has different phenotypes for a specific trait.

Here's a little bit more on the topic to help you out in the future:

Alleles are variant forms of genes. Each allele is found in a specific location of a chromosome and that location determines the trait that will be expressed.

There are two types of alleles: Dominant alleles and Recessive alleles.

A dominant allele is expressed physically while a recessive allele is the trait that is masked. If both alleles are present, the dominant allele usually masks the recessive allele. This phenomenon is called <u>complete dominance</u>. There are some traits where both alleles are equally expressed, which is called <u>co-dominance. </u>

Genotype is the set of genes present in an organism that is responsible for specific traits. Phenotype on the other hand is the physical expression of the trait, which depends on the genotype of the organism.

Alleles come in pairs, they could either be homozygous or heterozygous.

Homozygous pairs consist of either 2 dominant alleles or 2 recessive alleles. The genotype would look something like this:

2 dominant :RR                 or     2 recessive: rr

Heterozygous pairs consist of non-identical alleles, or it has one dominant and one recessive allele. So the genotype would look like this:

Rr

Finally, hybrid is the cross-breeding of two different species that are genetically different. There are many examples of hybrid species like the liger and the mule. The resulting off springs express traits that are different than both parents.

ad-work [718]

Answer: B- Bacteria

Explanation: Bacteria are infinitesimal organisms that have single cells that grow in different atmospheres. They have an easily understood inside arrangement. Their cells are normally surrounded by two shielding coverings which are an external cell continuous vertical structure and a cell pliable sheet-like structure acting as a boundary inside. However, some bacteria do have a third shielding sheet furthest from the center named the capsule.

5. Some undiluted acids are more corrosive when diluted
wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
