Why is oceanic crust subducted under continental crust?A. Oceanic crust is moving faster than continental crust.
B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.

Answers

Answer 1
Answer:

Answer:

B.) Oceanic crust is denser than continental crust.

Explanation:

Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.

I hope this helped. I am sorry if you get this wrong.

Is the definition of synthetic? Is it not real or a copy

Answers

Answer:

Explanation:

Synthetic is something that is not made from natural materials but rather made from the synthesis of other materials in a lab. This is mostly done in clothing where you have some natural materials like cotton and other materials that are synthetic. This doesn't mean it is not high quality. It is actually preferable for some sports for example to wear synthetic clothing instead of cotton.

What would cause a mammal to develop the anatomy of a female regardless of its chromosomes?

Answers

Answer:

The options are

a. A lack of estradiol.

b. Moderate levels of estradiol during an early stage of development.

c. A high level of testosterone during an early stage of development.

d. A high level of testosterone during the late part of puberty.

The answer is b. Moderate levels of estradiol during an early stage of development.

Testosterone is a hormone which is responsible for the secondary sexual characteristics of a male while estradiol is the hormone responsible for the secondary sexual characteristics of a female.

This is why estradiol is the hormone responsible in female development regardless of the chromosomes

Which of the following statements about primates is NOT true?a. All primates typically have five digits on each hand and foot.
b. All primates rely more on vision and less on their sense of smell.
c. Primates tend to have large brains in relation to their body size
d. Primates usually give birth to one offspring at a time.

Answers

Answer:

b. All primates rely more on vision and less on their sense of smell.

Explanation:

Primates make up a group of vertebrate animals and include apes (monkeys), lemurs and humans. All these beings have many similarities to each other, for example, all primates usually have five digits on each hand and foot, primates tend to have large brains in relation to body size and the larger the smarter brain the primate is, primates usually give birth one baby at a time. Not all primates rely more on sight and less on smell; humans tend to rely on sight more than on smell, but most other primates have more developed than humans, so the smell is more important to them.

The phase of mitosis that is characterized by the disappearance of the nuclear membrane is

Answers

Answer:

Prometaphase (late prophase)

Explanation:

Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.

According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.
