Which of the following statements accurately describes the process of dating Earth's history?a. Scientists use radiometric dating to determine the relative age of a new fossil.
b. Scientists use relative dating to determine the absolute age of a new fossil.
c. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
d. Scientists use index fossils to determine the specific years of age of a new fossil.

Answers

Answer 1

Answer: Radiometric dating and radioactive dating are two different names for the same method.

This method serves to determine the absolute age of a fossil: the correct answer is C.

Relative dating and index fossil both serve to determine the relative age of the fossils.

The cell cycle consists of two main phases: _____. interphase and M phase G0 phase and S phase M phase and S phase interphase and G2 phase

Answers

Answer: The correct answer is -

interphase and M phase.

Explanation:

Cell cycle can be described as a series of events that take place for the division of cell into two daughter cells.

It is primarily divided into two stages, which are-

1) Interphase (that is further divided into G1, S, and G2 phase) that involves the duplication of DNA and other proteins required in cell division.

2) M (mitotic phase) phase during which the nuclear division takes place through four successive stages that are prophase, followed by metaphase, anaphase and telophase.

After this cytokinesis (cytoplasmic division) occurs resulting in formation of two daughter cells.

Thus, first option is the right answer.

Interphase and M phase (Mitotic phase).

Interphase is when the cell is resting and preparing for division, M phase is when the cell is in the process of dividing.

What hormones does the pituitary gland produce?

Answers

The anterior pituitary gland produces growth hormone (GH), prolactin (PRL), follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH).
The posterior pituitary gland stores anti-diuretic hormone and oxytocin, both of which are actually produced in the hypothalamus.

Left thumb over right is dominant, and is represented with a capital C. Right thumb over left is recessive, and is represented with a lowercase c.What would be the genotype of a person who naturally crosses his right thumb over his left when folding his hands together?

A) cc

B) Cc

C) CC or cc

D) CC or Cc

Answers

Answer: Option A) cc

Explanation:

For a given gene, there are 2 or more alternative forms present, and they are known as alleles.
The alleles are of two types - dominant and recessive.
The dominant allele is the one which expresses itself in both heterozygous and homozygous condition in the phenotype.
The recessive allele is the one which is only able to express itself in homozygous condition.
Since, the right thumb over left allele c is recessive, the person who crosses right thumb over left must be a homozygote, and hence his genotype should be cc.

Suppose that a large river separates two populations of mice. one population is all black, and the other all white. a beaver dam that is built allows the mice to cross the river. over time, many gray mice are born. what is this an example of?

Answers

In this case two kinds of selection might be applicable to this situation. For example, if the population of grey mice are more exposed to predators due some materials used in the dam then that would be an example of disruptive selection. But if the population of gray mice is less visible to predators and if the population grow, then it will be an example of Stabilizing selection. Basicaly meant, this type of situation is also known as codominancy or codominant type.
