Which stage of the cell cycle involves the division of the cell’s nucleus?

One positive choice someone can make to help their health would be to exercise if you are overweight. One negative choice someone can make that can worsen their health would be drinking any alcohol. Exercising when overweight can help your health by decreasing chances of heart diseases and drinking any alcohol to an excessive extent can harm your liver which can lead to death or a journey of pain and complications.

POSITIVE: a positive choice would include is if someone is gaining so much weight, they can start a diet or an exercise plan. Due to this they will control their weight and won't get diabetes(from junk food sugar candy etc.)

NEGATIVE: a negative choice is to smoke which would cause lung problems. People smoke because they have an addiction, and they just can't stop. later on you can die due lung issues.

Chromosome and chromatid are closely related structures that are made from DNA molecules. Chromosomes contain genetic information in the form of specific DNA sequences or genes. A single strand of DNA is called a chromosome and two chromatids will form a single chromosome.

Answer:

Chromosome and chromatid  are related because there are both made from DNA molecules

Explanation:

Answer:

Had scientists been skeptical but not open minded about the idea,it would not have become scientific consensus.

Explanation:

The germ theory of diseases was logically proposed by Louis Pasteur and  between the 1860 and 1864 he performed series of experimentation to prove the relationship between diseases and germs.

Main postulate of germ cell theory:

The main postulate of germ cell theory was this that infectious diseases are caused by microbes or small organisms that invade the organisms and make him sick.

Was it accepted at once by scientists?

The germ theory was not accepted at once by all scientific communities because there were contemporaneous of this theory. Some scientists said that inner condition of a person’s cellular body actually determines whether he will suffer from disease or not. Others said that Every disease is associated with a particular condition or the diseases are caused due to unhealthy life style and many others.

How was it accepted:

It was by the middle of 1800s when the germ theory started getting acceptance from majority of scientists worldwide. This was because several experimentation were made around the world which proved that physical existence of germs is mandatory agent for the spread of diseases. During 1890s, viruses were also discovered and therefore a "golden period" of bacteriology started, which led to the approval of germ theory by scientists around the word and it became an accepted theory.

Coming towards the answer of question:

If the scientists always stayed skeptical and not open minded about the germ theory, it would never have gained acceptance and scientific consensus.

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Answer:

B) it enters the citric acid cycle and associates with a four carbon molecule form is citric acid and then through redox reactions jet regenerates the four carbon molecule.

Explanation:

Acetyl CoA enters the citric acid cycle and reacts with a four carbon compound, that is, oxaloacetate. The reaction forms citric acid (6 carbons) which in turn undergo redox reactions to regenerate the oxaloacetate and the released electrons are accepted by NAD+ and FAD+. The final products of citric acid cycle are CO2, H2O, NADH and FADH2.

The molecular conformation that facilitates crossing over is: tetrad.

Homologous chromosomes form tetrads composed of four sister chromatids. These chromatids are then able to cross over.

This happens during the stage of Meiosis I - in Meiosis II the tetrad has already split into pairs of sister chromatids.

The tetrad structure of homologous chromosomes facilitates crossing over during meiosis, promoting genetic diversity.

The molecular conformation of homologous chromosomes that facilitates crossing over is the tetrad structure. During the Prophase I of meiosis, homologous chromosomes pair up and form a structure known as a tetrad, which consists of four chromatids. The formation of tetrads is crucial for crossing over as it provides a physical basis for the chromosome to exchange genetic material. This process of crossing over results in recombination of genetic material, enhancing genetic diversity.

The process of sexual reproduction includes fusion of female and male gametes coming from both the parents. In the process of sexual reproduction, a new individual is produced due to the combination of two haploid gametes, one from the female parent, and the other coming from the male parent.  

The importance of sexual reproduction:  

1. The joining of DNA from two distinct individuals results in the increase in the genetic variation in the offspring.  

2. This further results in diversity in the population that assists in natural selection.

It's C , The reason is because as the seafloor spreads, new rock is symmetrically distributed to both sides of the ridge, so the rock on each side has the same pattern of magnetic orientation.

The statement that provides evidence to support the theory of seafloor spreading is as follows:

Thus, the correct option for this question is C.

Seafloor spreading may be defined as the process of construction of fresh regions of oceanic crust which takes place through the uplifting of magma at mid-ocean ridges and its ensuing outward movement on either side.

When this process of seafloor spreading occurs, recently developed rocks are symmetrically distributed to both sides of the ridge, And due to this, the rock on each side has an identical pattern of magnetic orientation.

This magnetic orientation plays a major role in the movement of tectonic plates apart at a divergent boundary located at the mid-ocean ridge.

Therefore, the correct option for this question is C.

Answer:

Yes they are identical.

Answer:

No they are not.

Explanation:

They’re antiparallel because the two strands are “built” in opposite ways: one runs from 3' to 5' while the other is a 5' to 3' direction, 3 and 5 indicating the number of carbon rings in the deoxyribose rings of the sugar-phosphate backbone. It has nothing to do with the coding itself.

Answer:

The greenhouse effect is a natural process that occurs due to the accumulation of greenhouse gases such as carbon dioxide, ozone, methane in the earth's surface.

Explanation:

The greenhouse effect is a phenomenon that occurs when the greenhouse gases(carbon dioxide, methane) in the Earth's surface trap heat from the sun and this process makes the Earth's surface warmer.

The greenhouse effect is caused due to burning of fossil fuels and cutting of trees or forests, which increase the concentration of methane, carbon dioxide(greenhouse gases).

The greenhouse effect is a natural mechanism that raises the temperature of the Earth's surface. It occurs when specific gases in the atmosphere capture solar radiation.

The greenhouse gases allow sunlight to enter the atmosphere while trapping heat reflected from the Earth's surface. This trapped heat raises the temperature of the Earth's surface and lower atmosphere.

Its effect is necessary for life on Earth to exist. The average temperature on Earth would be around -18 degrees Celsius (-0.4 degrees Fahrenheit) if the greenhouse effect did not exist.

The effect of geographic isolation is that the two populations are subjected to different selection (pressures) and geographic conditions. The conditions in the two areas, if different, will produce different alleles in that species and will be selected for, where genetic differences will gradually accumulate between the two different populations.

In time, enough genetic differences will occur so that the two populations will no longer interbreed. Then, by definition, they have become different species.

The answer is The brown paper test for lipids is positive when food is placed on the paper and a spot forms that will allow light to pass through it. Which food would give the strongest positive test for lipids? The answer is Potato chips

A food high in fat, such as butter or olive oil, would yield the strongest positive test for lipids because they are high in lipid content. A solution like the Sudan III stain can be used to visually identify the presence of lipids in a food source.

A food that would give the strongest positive test for lipids would be one that is high in fat. For instance, butter or olive oil would yield a strong positive result because they are both very high in lipids.

In a lab, this can be tested using a solution such as the Sudan III stain, which binds to fats and can be visually seen if fat is present. If the solution turns a red color, that indicates the presence of lipids. Given the high lipid content in butter or olive oil, these would react strongly to the solution, indicating a high amount of lipids.

Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. ... This hot added material cools down by conduction and convection of heat.

Convection is the type of heat transfer that causes material in the Earth's interior to move, affecting the movement of tectonic plates.

The type of heat transfer that causes material in the earth's interior to move is known as convection. This process involves convection movement within a gas or liquid, driven by the tendency of hotter, and therefore less dense material, to rise while colder, denser material sinks due to gravity. This results in a transfer of heat. In the Earth's mantle, this movement forms convection cells that drive the movement of tectonic plates. Hotter and less dense mantle material heated above the core rises towards the surface, cools, and then sinks back down at places such as deep sea trenches, completing a convection cell and perpetuating the cycle of heat transfer.

Q 1) How different are the wet and dry earwax genes?

Answer:

switch of a single DNA unit.

Explanation

There is a specific gene that is associated with the ear wax and determine whether the people will have dry ear wax or wet ear wax. This gene is known as "ATP-binding cassette C11 gene"

Dry wax type individuals are homozygous for the gene while wet wax type individual have a difference of only one base where adenine is replaced by Guanine.  While wet wax type individuals are heterozygous for the gene which means that wet wax type gene is dominant over dry wax type gene.

So we can say that the genetic difference between two genes i due to a mutation that occurred and changed only a single DNA unit base due to which two phenotypes dry and wet ear wax developed.

---------------------------------------------------------------------------------------------------

2) Why is earwax important?

Answer:

It is like biological flypaper, prevents dust and insects from entering the ear.

Explanation:

Ear wax is also known as cerumen in medical terms which consists of orange, gray or yellowish waxy material. This material is secreted by  ear canal  in mammals including humans and this has very important role in human life.

The ear wax helps in the lubrication of ear which serves an important role to protect the ear against insects, fungi, water excess and bacteria.

If we see from outside, this ear wax is comprised of hair,skin cells and secretions from sebaceous  and ceruminous glands. The major part of ear wax are unsaturated and saturated  fatty acids, squalene, cholesterol and alcohols.

In severe cases, ear wax can also cause blockage of ears due to excessive deposition of wax which can lead to serious hearing disabilities.

---------------------------------------------------------------------------

3) Those of us who tend to sweat a lot and have armpit odor probably have what type of earwax?

Answer:

Wet earwax

Explanation:

Studies have reported that individual with wet ear wax particularly have more armpit odor due to enhanced production of sweat.Research suggest that the less sweat or body odor was useful for Native Americans  and  East Asians who used to live in a cold environment and therefore they had dey ear wax. The mutation causing wet ear was specifically is prevalent area wise in more dry areas of the world like Ainu in Japan however as well as Yamato in Japan.

-------------------------------------------------------------------------------------------------

Q 5: If a person with wet earwax had offspring with a person who had dry earwax and all 200 of their children had wet earwax, what would be the genotype of the parent with wet earwax?

Answer:

WW

Explanation:

As we just studied that wet ear wax trait is dominant over dry ear wax trait, it means that a single copy of dominant allele W is enough for the offspring to have wet ear wax. So is question, it asked that a person with wet ear wax married a women with dry ear wax and had 200 offspring. All the offspring had wet earwax, so it clealry means that their father was homozygous for wet ear was alleles.

Let us see how:

P1:                                 WW    x ww

Gametes:                      W         :  w

Offspring:                     Ww: Ww

So, it means that if all offspring had wet ear wax it means that both parents were pure breeding for respective wax types, dry and wet ear wax. Otherwise there would be some proportion of offspring having wet ear wax as well.

Hope it help!
