How are meiosis and mitosis different?

Answers

Answer 1

Answer:

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Answer 2

Answer: Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

. Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

Answer:

A. Stay at rest

Explanation:

Since no other forces are applied to the object, there is nothing that can move the object since the forces are balanced.

Answer:

A. stay at rest

Explanation:

This is true because for example if a feather is left alone it will not move but if an outside force such as your hand or the wind applies force on it it will move.

A skeleton is found that has a narrow pelvis, large occipital protuberance, and a sloping forehead. Is the skeleton a biological male or female? Justify your answer with an explanation on how you came to your conclusion.

(Forensics)

Answers

Answer: Male

Explanation:

The pelvis is narrow in males, the pubis arch is 90 degrees in angle. It is broad in case of females to support pregnancy and child birth. Also the pubis arch is more than 90 degrees in angle. An occipital protuberance is a region that connects the head to the neck and it is generally larger in males than in female. In males the forehead is sloping in the cranium whereas that in females it is vertical and flat.

Hence, the skeleton have the features that can be indicated towards the features of a male.

B. It decolorizes the cells.
C. It dries out the cells.
D. It shrinks the cell wall.​

Answers

Answer:

the answer to this question is a

The statement which is not true of the purpose of the alcohol in Gram staining is as follows:

It binds the crystal violet into the cell wall.

Thus, the correct option is A.

What is Gram staining?

Gram staining may be defined as a methodology that is utilized for the classification of bacterial species such as gram-positive and gram-negative.

In gram staining, ethyl alcohol or acetone is used as a decolorizer that dehydrates the peptidoglycan layer. It involves the shrinkage or tightening of the cell wall.

In this process, the large crystal violet-iodine complex is not able to puncture this tightened layer of peptidoglycan.  

Therefore, the correct option for this question is A.

what is produced by mitosis?

Answers

When a parent cell splits to create two identical daughter cells, the process of the nuclear division known as mitosis takes place in eukaryotic cells.

What is meant by mitosis?

DNA, a molecule found on chromosomes, is the genetic information carrier. They are linearly arranged genes that are present in couples in the cell's nucleus. Genes also are arranged in pairs, and each pair produces a coding that results in the production of a distinct protein.

Mitosis is a sort of cell division that makes sure each new daughter cell formed when a cell splits possess the same genomic structure.

Two cells referred to known as daughter cells are created during mitosis. Any newly formed daughter cells must have genetic material that is similar to that of the parent cell, and the number of chromosomes must stay constant.

Therefore two identical daughter cells are produced as a result of mitosis.

Heliocentric Model

The Sun is at the center of the solar system.

The orbits of the planets are elliptical

Includes eight planets.

The solar system

Explanation:

The main difference between the heliocentrical and geocentrical model is that in the first one, the Sun is in the center and the planets are around it, while in the second model, the Earth is in the center and the Sun, the moon, and the planets are around it.

Also, the geocentrical model stated that there were five planets, Mercury, Venus, Mars, Jupiter, and Saturn. These planets had circular orbits. In other words, they have a circular motion around the Earth, and this one was still in the center of the system.

In the heliocentric model, there are eight planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, and they all rotate in elliptical orbits around the Sun. The Heliocentric model is also called the solar system since its central star is the Sun, and the planets are around it.

Explain the various phase of menstrual cycle with reference to changes in ovary and uterus and hormonal cycle.

Answers

Answer:

In the follicular phase, the follicles grow inside the ovary. The ovulatory phase is the time of greatest fertility for women. In it, estrogen levels peak just before the egg is released. In the luteal phase, after ovulation the follicular structure that remains in the ovary reorganizes and becomes a gland known as the corpus luteum. The self-determined life of the corpus luteum causes it to degenerate after 14 days and end a menstrual cycle. At the end of the luteal phase, progesterone and estrogen levels drop and menstruation occurs.

Explanation:

The follicular phase is where follicles develop (fluid-filled cavities in the ovary that contain an undeveloped egg) that will eventually house the egg. For the development of follicles, the body sends a signal to the brain to start the production of follicle stimulating hormone (FSH), the follicles begin to develop and produce estrogen. In the ovulatory phase, the level of estrogen in the body continues to rise, causing a rapid rise in LH. This increase causes the secretion of proteolytic enzymes that will degrade the follicular tissue allowing the maturation process of the ovum and its release to finish, a fact known as "ovulation". Ovulation usually occurs between 24 and 36 hours after the LH surge, so luteinizing hormone is a good factor for measuring the period of maximum fertility and knowing the fertile days of the woman. In the luteal phase, the corpus luteum develops that will last until a possible pregnancy or menstruation occurs, starting the next cycle. The egg, after being released, travels through the fallopian tube to the womb. It can survive up to 24 hours and sperm up to 5 days inside the uterus, therefore the days before ovulation and the day of ovulation itself, which can be calculated with the ovulation calendar, are those of maximum fertility and higher chances of pregnancy. After ovulation, the follicle begins to contract but continues to produce progesterone and begins to produce estrogen in order to continue preparing the uterus to receive the embryo.

Answers

Answer:

a. low hemoglobin levels despite high elevation in Tibetan populations over generations.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

A suggested evidence of natural selection at work in humans is the observation of low hemoglobin levels despite high elevation in Tibetan populations over generations. This is as a result of a low level of oxygen in the blood of a living organism such as humans.
