When two different sperm fertilize two eggs,

a.) fraternal twins result.
b.) identical twins result.
c.) twins of different sexes always result.
d.) twins of the same sex always result.

Answers

Answer 1

Answer:

When two different sperm fertilize two eggs, fraternal twins result (option a).

Explanation:

Fraternal twins are the result of the separate fertilization of two maternal eggs by two paternal sperm, with the obtention of two zygotes with different DNA.

Although the embryonic development of fraternal twins occurs at the same time in the maternal uterus, each embryo will have an individual placenta and embryonic sac, with different development and characteristics, sometimes including sex.

The other options are not correct because:

    b. Identical twins come from the division of the zygote after fertilization, obtaining siblings with the same DNA and who share the same placenta and embryonic sac.

    c. Twins of a different sex do not always occur.

    d. Same sex twins always occur when they are identical twins.

In the United States, the onset of puberty has been occurring earlier and earlier. Today, about 10 percent of children ages 6 or 7 begin developing signs of puberty, a condition known as precocious puberty.

In the early 1900s, girls typically began menstruating at age 17. Today, girls typically begin around age 12. This trend has been attributed to the growing number of overweight children and a greater exposure to pollutants. Exposure to phthalates, artificial chemicals found in plastics, has also been cited as a cause. These chemicals disrupt the endocrine system by mimicking hormones in the body.

Early puberty can have many negative side effects, including an increased risk of certain types of cancer, such as breast cancer. Children are often emotionally unprepared for the physical changes taking place in their bodies. As a result, behavioral and psychological problems may increase.

A student is given two mineral samples that appear very similar. They both are opaque, white, and shiny. He knows that they are either calcite or quartz. To determine the identity of each mineral, the student puts a couple of drops of hydrochloric acid (HCl) on each sample. When calcite reacts with hydrochloric acid, carbon dioxide gas is produced. When HCl is placed on quartz, no changes are observed. Based on the information above, what evidence indicates that a chemical reaction occurs when HCl is placed on calcite?

Answers

Answer:

Carbon dioxide is a new product formed from the reaction between calcite and HCl

Explanation:

Calcite is a mineral with the chemical formula CaCO₃. Hydrochloric acid reacts with calcite to liberate carbon dioxide and form calcium chloride and water. The equation of the reaction is given below:

CaCO₃ + HCl ----> CaCl₂ + H₂O + CO₂

In a chemical reaction or change, new products are formed which are different from the original elements or compounds reacting.

Since the carbon dioxide gas, calcium chloride and water are entirely new products formed from calcite and hydrochloric acid, the reaction between calcite and HCl is a chemical reaction.

Answer:A

Explanation:

Carbon dioxide is a new substance created from the calcite and hydrochloric acid

B. constructive coping
C. catharsis
D. appraisal

Answers

Answer:

the flight or fight response

Explanation:

got it correct on edg, 100%

The alarm stage of Hans Selye's general adaptation syndrome is very similar to the flight-or-fight response, hence option A is correct.

What is the flight-or-fight response?

The fight or flight response is a physiological response that occurs automatically in response to a stressful or frightful experience.

Threat perception engages the sympathetic nervous system, causing an acute stress reaction that primes the body for either fighting or running away.

Because your blood flow is being changed, you can feel chilled or notice that your hands and feet are damp and cold.

As your body's blood and hormones flow, your face could also seem flushed. The ability to feel sharp pain is impaired.

Therefore,  the flight-or-fight response and alarm stage of Hans Selye's general adaptation syndrome is similar.
