What are somethings that cause mutations in cancer

2 answers:

These acquired mutations cause most cases of cancer. Some acquired mutations can be caused by things that we are exposed to in our environment, including cigarette smoke, radiation, hormones, and diet. Other mutations have no clear cause, and seem to occur randomly as the cells divide.

Which of the following statements is correct?

Keith_Richards [23]

Answer:

The statement that is correct is that all cells have the same genes, but different genes are active in different cells.

Explanation:

Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.

Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.

All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation.

The other choices are wrong because:

The eyes look different from the liver, because they have the same genes, but only some are expressed.
Differentiated cells and tissues do not lose their genes.
All cells have DNA.

a black rooster Mated with a white hen. based on genotypes, the chance that the offspring will be checkered is 100 percent. what

gtnhenbr [62]

Answer:

The genotypes of the rooster and the chicken are homozygous and that of their offspring is heterozygous.

This case is called codominance, where the offspring receives an allele from each parent, from the rooster and the hen, because there is codominance, so neither allele is recessive and the phenotype of both alleles is expressed so the phenotype of the offspring is checkered.

We can say then that the chicken and the rooster have equal strength between their alleles. in the cases of codominance the laws of mendel do not apply.

Upon examining samples of water and mud from a nearby river, you come across an unidentified organism. The organism is unicellul

Tasya [4]

Answer:

A protist

Explanation:

In the given question, the characteristic of an unidentified organism are given which are:

1. The organism is unicellular and autotrophic which means that it is a producer and belongs to a plant like organism.

2. The membrane bound nucleus means that the organism is an eukaryote.

The organism is thus an unicellular, autotrophic and an eukaryote could be a species of algae which is considered a protist. The protists are the organisms which shows characteristic of the ukaryotes but are not considered true plants and animals.

Thus, a protist is correct answer.
