What is the second phase of mitosis

Answers

Answer 1

Answer:

Answer:

Metaphase

Explanation:

During metaphase, parts of the spindle extend and the chromosomes align at the middle part of the cell. Notice that each chromosome consists of two identical strands held together at a point in the middle.

-Therefore, metaphase is the second stage of mitosis

Answer 2

Answer: Metaphase

The second stage of mitosis. In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere.

Which observation proves that a cell is a eukaryote?. A)It contains DNA. B)It has DNA inside a nucleus.. C)It has a cell membrane.. D)it contains ribosomes.

Answers

Which observation proves that a cell is a eukaryote?

Answer: Out of all the options that are shown above the one that is an observation that is used to prove that a cell is a eukaryote is answer choice B) It has DNA inside a nucleus. Also Eukaryote cells have a nucleus and membrane-bound organelles.

I hope it helps, Regards.

Answer: B) It has DNA inside a nucleus.

An eukaryotic cell is the cell which exhibit membrane bound organelles. They exhibit a well defined membrane bound nucleus in which the DNA (deoxyribo nucleic acid) resides it is the genetic material which is passed on from parents to their offsprings. This property of the eukaryotic cell makes it distinct from prokaryotic cell as the prokaryotic cell lack a nucleus.

All of the following are important roles of the skeletal system exceptA. organ protection
B. movement
C. storing minerals
D. regulating body temperature

Answers

The answer is D. The ribs PROTECT the lungs and the heart. They allow you to move and they store minerals such as calcium. However it is the brain and the blood vessels that regulate the body temperature not the skeletal system.

In the first paragraph, UCLA climate scientist Daniel Swain claims, " We've gotten to the point where when it comes to extreme heat waves, there is almost always a human fingerprint." Explain: What does Swain mean?

Answers

Answer:

It means human is responsible for everything.

Explanation:

Swain who is climate scientist mean that the heat waves occurs due to the human intervention and activities. Human is responsible for the change occurs in climate and global warming. In some areas heat waves occurs which adversely affected human as well as animals and plants. Heat wave is a period of hot weather occurs due to emission of greenhouse gases which increase the temperature of the earth's surface.

An obstetrician knows that one of her patients is a pregnant woman whose fetus is at risk for a serious disorder that is detectable biochemically in fetal cells. The obstetrician would most reasonably offer which of the following procedures to her patient? A) CVS
B) ultrasound imaging
C) amniocentesis
D) blood transfusion
E) X-ray

Answers

The obstetrician would most reasonably offer procedure CVS (Chorionic Villus Sampling) to her patient. Therefore option A is correct.

CVS is a prenatal test performed between 10 to 13 weeks of pregnancy. It involves taking a small sample of cells from the placenta to analyze the fetal DNA for genetic disorders.

This procedure allows early detection of serious disorders, providing valuable information to the parents about the health of their fetus. Ultrasound imaging can provide structural information about the fetus but may not detect biochemical disorders.

Amniocentesis is typically performed later in pregnancy and is used for different purposes. Blood transfusion and E) X-ray are not relevant to detecting fetal disorders.

Therefore option A is correct.

Definitely not XRAY (insert facepalm emoji) Most likely a Choroid villus sample but amniocentesis also seems reasonable. AHHH Amniocentesis is the answer :) Since it is used to see what is going on with the fetal cells.
