choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer

Answers

''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.

Why earth's crust is considered an egg shell?

The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.

So we can conclude that option A is the right answer about the earth's crust.

explain the process of dialysis.. and who invented/ discovered this process?

Answers

The history of dialysis dates back to the 1940s. The first type of dialyzer, then called the artificial kidney, was built in 1943 by Dutch physician Willem Kolff. Kolff had first gotten the idea of developing a machine to clean the blood after watching a patient suffer from kidney failure.

One needle will slowly remove blood and transfer it to a machine called a dialyser or dialysis machine. The dialysis machine is made up of a series of membranes that act as filters and a special liquid called dialysate. The membranes filter waste products from your blood, which are passed into the dialysate fluid.
The first scientific descriptions of these procedures dates back to the 19th century and came from the Scottish chemist Thomas Graham, who became known as the “Father of Dialysis.”

Explain how mRNA is formed from the DNA template.

Answers

Answer:

mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

When resources are stable over a long period of time, a species' population can be expected to
O die out.
o increase.
O stay the same.
O decrease.

Answers

The population would increase

In an environment with stable availability of resources, the population can still grow because there are enough resources for this population to survive. Option B. The species' population can be expected to increase.

This question is related to growth models.

Logistic growth

A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.

The population growth per capita rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

Carrying capacity

Carrying capacity refers to the maximum point at which the environment can support a growing population.

K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.

• If the population size, N, is inferior to K (N<K), the population can still grow.

• When N approximates to K, the population´s growth speed decreases.

• When N=K, the population reaches equilibrium,

• When N is superior to K (N>K), the population must decrease in size because there are not enough resources to maintain that size.

So when the population size exceeds K, carrying capacity makes the population decrease in size.

But if there is a constant availability of resources, the population can still grow because there are enough resources for this population to survive. In this situation, N<K.

When resources are stable over a long period of time, a species' population can be expected to INCREASE. Option B.

The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.

The processes of diffusion and active transport are both used to * break down molecules to release energy move molecules into or out of cells of the body bring molecules into cells when they are more concentrated outside of the cell move molecules against a concentration gradient, using ATP molecules

Answers

Answer:

move molecules into or out of cells of the body

Explanation:

Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.

On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.

Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.

During which phases of the cell cycle are chromosomes composed of two chromatids?

Answers

Answer:

The correct phases are S phase, prophase, anaphase.

Explanation:

The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.

From Mendel's first set of experiments, he concluded that
