8. Outline the process of metaphase, inclusive of the role of microtubules and the centromere.

Answers

Answer:

Chromosomes are positioned in the middle of the cell during metaphase.  

Explanation:

During metaphase, the centrosomes are at opposite poles or sides of the cell.  The spindle apparatus is formed and the nuclear membrane has dissolved.  The spindle fibers, also known as microtubules have lined up the chromosomes along the equatorial plate in the middle of the cell so each sister chromatid faces opposite directions.  The sister chromatids are still connected by the centromere, and this is the last time they are connected during this division.  The centromere is also where kinetochores assemble, and kinetochores are the sites of attachment for microtubules to pull the sister chromatids apart.  They are important for the cell to be able to divide.

Why does your vaccination status affect more people than just you?

Answers

Answer:

so i belive ur talking about the corona vaccinations so my answer is below! :D

Explanation:

if you get vaccinated, you are helping yourself and other people because it is most likely that you wont get corona if u have a vaccine. When you dont get corona that means that there are less people dying and you will reduce the level of deaths because ur not gonna get corona and give it to someone else. Once you get the vaccine you still have to be protected and wear a mask when you go outside just in case to protect your self and someone elses life. So, thats why ur vaccination status affects more people than just you. :D

also i just realized that you might not be talking about the corona vaccinations and u can be talking about the normal vaccines but the paragraph that i just wrote can be meant for normal vaccines as well :)

What are stem cells? How are embryonic stem cells different from adult stem cells?

Answers

Answer:

Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated.

Embryonic stem cells are derived during early development at the blastocyst stage and are pluripotent, meaning that they can differentiate into any cell type. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

Plants take in carbon dioxide and release gas​

Answers

Answer:

yes, but by gas you mean oxygen right?

Explanation:

Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Explanation:

what is cellular respiration also called

Answers

Answer:

Krebs cycle, tricarboxylic acid cycle.

Explanation:

Cellular respiration is what cells do to break up sugars to get energy they can use. ... Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.

Answer:

Alternative Titles: cell respiration, tissue respiration. Discover how cellular respiration transforms your food into energy usable by your cells. Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

Blood type is a genetically determined trait. Two siblings donate blood and find out their blood types. The brother is Type A and the sister is Type
B. Which of the following best explains why the siblings have different blood types?
A. The brother has a different number of blood type genes than his sister.
B. The brother's blood type gene is on a different chromosome than his sister's.
c. The brother has different alleles for the blood type gene than his sister does. D. The brother has a different number of chromosomes than his sisted does

Answers

Answer:

C

Explanation:

The brother has different alleles for the blood type gene than his sister does.  Blood type is inherited from parents like many other traits that can be displayed on a punnet square.  Depending on what the parents blood type alleles were, the brother and sister could have different blood types.  

A different number of chromosomes doesn't lead to different blood types, so D is wrong.  And A is incorrect because the number genes also does not affect blood type.  And I think the blood type genes are on the same chromosome, so B is wrong.  C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.

Answers

Answer:

The correct answer is - Archaea.

Explanation:

Archaea is one of the three domains of life other than bacteria and eukarya. Archaea are prokaryotic organisms that are unicellular and present in very extreme conditions like salt environments or extreme heat.

Archaea used to be placed with bacteria but due to some closeness with the characteristic of eukarya as well as bacteria, it is placed as a separate domain. It lacks nuclei and has a cell wall in its cell.

Why might someone who is on a diet and eating very few molecules not lose weight?

Answers

Yet as we gain weight our bodies become less sensitive to leptin, and it becomes harder and harder to slim down. In other words, weight gain begets more weight gain. In an experiment using mice that became obese on a high-fat diet, an international team found obesity increases the activity of an enzyme called matrix metalloproteinase-2, or MMP-2. By using a technique called western blot analysis—separating and identifying all the proteins in a tissue sample—the authors found MMP-2 cleaves off a portion of the leptin receptor in the hypothalamus, impairing the hormone’s signaling and its ability to suppress appetite.

a. insertion of RNA primer sequences
b. sealing the gaps between fragments
c. opening multiple origins of replication
d. proofreading new DNA strands

Answers

Answer:

D

Explanation:

Key points:

- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.

- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.

- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.

- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.

Why do you think having such an extensive membranous area is beneficial when performing photosynthesis?

Answers

Answer:

Increasing the membrane area also increases the number of ATP and NADPH generating sites

Explanation:

Photosynthesis occurs in the chloroplast, more precisely in the membranes of the thylakoids that form stacks of disks called grana. A mature chloroplast may have 20 to 60 grana. In these membranes, there are photosystems, which are structural units of pigment-protein complexes that convert light energy from the sun into chemical energy stored in ATP and NADPH. A thylakoid may contain thousands of photosystems. In consequence, increasing the membrane area also increases the number of photosystems required for the synthesis of ATP and NADPH.
