Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.
Mitosis has only one round of cell division, while meiosis has two. Mitosis only occurs in body cells, while meiosis occurs in sex cells. Mitosis produces daughter cells, that are identical to the parent cell, while mitosis produces haploid/diploid cells that only have half of the normal number of chromosomes.
Gas exchange involves the transport of two respiratory gases, oxygen and carbon dioxide. Review how each gas is transported between the atmosphere and the cells of your body by completing this exercise.1. required for cellular respiration
2. net diffusion from alveoli to lung capillaries3. sometimes transported as bicarbonate
4. net diffusion from body tissues to blood
5. net diffusion from lung capillaries to alveoli
6. waste product of cellular respiration7. enters alveoli during inhalation
8. transported by hemoglobinA. Oxygen onlyB. Carbon Dioxide OnlyC. Both Oxygen and carbon dioxide
Answer:
When we breathe, we inhale oxygen and we exhale carbon dioxide.
Explanation:
1. For the cellular respiration, the body cells are provided with oxygen during gas exchange in respiration.
2. Oxygen gas diffuses from alveoli to the capillaries in our lungs.
3. Carbon dioxide is always transported in plasma or bounded to the hemoglobin or in some form of bicarbonate.
4. Carbon dioxide gas diffuses from our body tissues to the blood.
5. In our lungs, carbon dioxide gas diffuses from capillaries in to alveoli. Carbon dioxide leaves the body when we exhale.
6. During cellular respiration, we give give out and removes carbon dioxide from our body which is a waste product.
7. When we inhale, both oxygen and carbon dioxide gases enters the alveoli,
8. All the oxygen present in blood is bounded by hemoglobin and it is carried to all the body tissues and body and diffuses from our blood to our body tissues.

A farmer planted broccoli during winter. Which crops should he plant now especially after three months of frost?
Answer:
Cauliflower
Explanation:
Because Cauliflower is the closest relative to Broccoli, it is the best option. The soil and the nutrients in the soil will have become suited for broccoli, so you want to put something similar in the soil so that the new plant thrives.

A student found that 3 grams of ammonia gas formed 3 grams of solid ammonia when the
temperature was lowered enough. Why did the solid ammonia and the ammonia gas have the same
mass?
Answer:
The mass of a substance is constant according to the law of conservation of mass.
Explanation:
According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.
This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.
What happens when a cell reaches the Hayflick limit ? Why does this have to happen for the health of the cell?
Answer:
The Hay-flick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.

Explain 2 reasons of why burning down a forest increases the carbon dioxide in the air. NEED TO Know ASAP!
Explanation:
The surplus carbon is stored in the plant, helping it to grow. however when trees are cut down and burned or allowed to rot, their stored carbon is released into the air as carbon dioxide .
Answer: because the lesser trees the more carbon dioxide there will be plus your burning them down which just polluted it even more because the fire is releasing a lot of carbon dioxide

An acentric fragment is one result of crossing-over between a normal chromosome and a chromosome that has undergone what kind of mutation?
Answer:
paracentric inversion
Explanation:
A paracentric inversion happens as a result of a portion of one chromosome , or a packet of genetic information, which is flipped such that there are changes in the order of genetic information. Every of the chromosome has a part that is near the middle which is referred to as a centromere. Paracentric inversions do not include the involvement of the centromere of a chromosome.

Consider a duplex molecule of length 10 Mb that has only one origin of replication located exactly in the middle. If replication proceeds bidirectionally, assuming that the rate of DNA synthesis is 1500 nucleotide pairs per second, the time needed for replication of this molecule is _____ minutes.
Answer:
Approximately 28 minutes.
Explanation:
Given:
Length of a duplex molecule of DNA = 10 mb
= 10 * 10^6 bases
So, it means each DNA has = 5 * 10^6 base pair
rate of DNA synthesis = 1500 nucleotide pairs per sec.
location of replication = at the middle which is 5 * 10^6/2
= At 2.5 * 10^6
solution:
As we know replication of DNA is a bidirectional process so it will synthesize in both directions and the rate is given is 1500 nucleotide per sec so the time required to replicate 2.5 * 10^6 in both directions will be from the formula
time = distane/rate
= 2.5 * 10^6/1500
= 1666.66 seconds
or, 28 minutes aprrox (27.77)
