Nonconservative elements are non-reactive in seawater and have a short residence time.

Explanation:

Non conservative elements are elements that enter the sea water and have little concentrations in the ocean and show spartial variationns. These elements have short residence time I .e short replacement time and they are non reactive .Constituents such as phosphate, nitrate, and other nutrients, and dissolved oxygen, carbon dioxide, etc. are non-conservative because their concentrations are later changed by chemical reaction in the sea.

During interphase the cells copies it’s DNA. In the pictures it shows a chromatid duplicating into a sister chromatids.

The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).

Moreover, interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Answer:

they open up to get the energy from the sun.

Explanation:

Answer:

Este es un ejemplo de dominancia incompleta. Es una ocurrencia genética que ocurre cuando un gen dominante no expresa su manifestación completa en el alelo recesivo en un alelo dominante heterocigoto.

Por lo tanto, ambos rasgos se manifiestan, lo que resulta en la combinación de los dos alelos para los colores (blanco y rojo). Se dice que el alelo rojo dominante exhibe un dominio parcial sobre el alelo blanco recesivo, y esto da como resultado el alelo completamente rosado.

De acuerdo con la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas heterocigóticas dominantes deben ser R. El alelo blanco es recesivo (rr) enmascarado por el rojo R,

Sin embargo, cuando se cruzan los dos alelos heterocigotos rojos:

Los fenotipos están en forma de

RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.

Esto ocurre porque el alelo rojo dominante no era total / completamente dominante en el alelo recesivo blanco en cada uno, lo que da como resultado un alelo rosa (el tercer fenotipo)

This is an example of incomplete dominance.It is a genetic occurrence  which occurs when a dominant gene does not express it full manifestation on the recessive allele in an heterozygote dominant allele.

Therefore,both traits are manifested which results in the blend of the two allele for colors(white and red).The dominant red allele is said to exhibit partial dominance over the recessive white allele.And this results in the entirely pink allele.

Based on Mendelian law the  two red flowers are  heterozygotes .Therefore, Red heterozygote dominant flowers should beRr.The white allele is recessive(rr) masked by the R-red,

However,when the two red heterozygote alleles are crossed:

The phenotypes are in the form of  

RR,(1) red  Rr Rr(2) pink  rr(1)White.

This occurs because, the dominant red allele was not fully/completely  dominant on the  white recessive allele in each,which results in pink allele(The third phenotype)

Explanation:

The branch of science which deals with living beings is called biology.

The language of the question is different so it is difficult to answer it.

According to the data given in the question, they are discussing incomplete dominance because the ratio is 1:2:1.

The cross in which the dominant parent is not able to show its character and does not able to suppress the recessive gene. In this case, the plants show the character of somewhere in between both of the cases.

Therefore, they get the ratio of 1:2:1 which indicates the phenotype of red: pink: white.

Hence, the correct answer is incomplete dominance.

Answer:

Explanation:

Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.

The reduction is accomplished by 2 divisions after the duplication of chromosomes

- first division: separation of homologous pairs of chromosomes (this reduces the total in half)

- second division: separation of sister chromatids of a chromosome.

The rearrangement in meiosis occurs by crossing over/genetic recombination.

This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation

An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.

This condition produces offsprings that have some characteristic facial features, short stature etc

Rearrangement takes place at the time of meiosis with the lining of chromosomes pair during the metaphase 1 and 2. Down syndrome is the example of chromosomal abnormality.

• A process in which a single cell differentiates two times to generate four cells comprising half the original amount of genetic information is termed as meiosis.

• During meiosis, the process of rearrangement takes place when the chromosomes line up in pairs at the time of metaphase 1 and 2. Then in anaphase 1 and 2, the separation of these chromosomes takes place and each gamete gets one of each kind of chromosome.  

• One of the examples of chromosomal abnormality is Down syndrome, which is, illustrated by the third copy of chromosome 21. The phenotypic variability, which takes place during Down syndrome is muscle hypotonia at the time of birth, and cognitive impairment.  

Thus, during meiosis reduction and rearrangement of chromosomes takes place, and one of the chromosomal abnormality is the Down syndrome.

The greenhouse effect is an essential phenomenon for life on earth. However, human activities such as pollution and burning of fossil fuels have caused an intensification of this effect, which has harmed the atmosphere and is directly related to global warming.

The greenhouse effect is formed by a layer of atmospheric gases that settle around the planet and allows a temperature suitable for life to reach the earth's surface. Therefore, we can guarantee that this effect is essential for our survival. It is necessary that the amount of these gases is kept in equilibrium for this temperature to be constant.

However, the burning of fossil fuels, industrial activities, pollution (caused by vehicles, aerosols, fires, among others), the use of non-renewable energy releases greenhouse gases into the atmosphere daily and in large quantities.

This causes the layer of greenhouse gases that circulates the earth to become more and more expanded, not being able to disperse solar radiation easily and causing an increasing temperature. All that heat is retained in the atmosphere, thus generating global warming, which allows the planet's temperature and ocean water to increase dramatically, which can cause various harmful effects to life on the planet.

For this reason, it is necessary to carry out public policies that reduce pollution and encourage the use of clean and renewable energy that does not increase the layer of greenhouse cases, promoting well-being and life on earth.

The clarity of the lake water though not specified in this context. The full

body plate will help the stickleback fish to escape from its predators.

Water clarity is defined as the amount of light which is able to penetrate into

water bodies thereby making it easier for animals in it to see and hunt

Diffusion

Explanation:

The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.

Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.

Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.

My reasoning is that, if they evolved from land-dwellers to tree-dwellers, they will have almost no need for longer legs for running, as they only need strong legs and arms for climbing, not running.

The ability to communicate better doesn't really mean anything, as they are now all closer or further away, since they are all in trees now. This doesn't mean that they necessarily need to communicate better.

The ability to have several offspring at one time could be the answer, but isn't really necessary.

Predators would hunt for the koalas in the trees now, so to hide, they would need to go inside the tree trunk or camouflage themselves, which most creatures do by blending into their surroundings or changing skin color over time.
