What happens when magma cools during the rock cycle? Igneous rock is formed. Metamorphic rock is melted. Sediments form sedimentary rock. Metamorphic rock forms sediments.

Answers

Answer: igneous rock is formed

Explanation:

When magma cools down during the rock cycle then igneous rock is formed. Thus, the correct option is A.

What are Igneous rocks?

Igneous rock is one of the three main rock types, while the other being sedimentary and metamorphic rocks. Igneous rocks are the rocks formed through the cooling and solidification of magma or lava from volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.

Lava from the volcano cools to form volcanic rock as well as volcanic glass. This magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma then solidifies in the atmosphere to form volcanic rock called as tephra. In the atmosphere, tephra is more often called as volcanic ash.

Therefore, the correct option is A.

A multicellular organism begins life as a single cell-a fertilized egg with a
complete set of chromosomes. The picture in Figure 10-2 above shows how the
cell divides to become two cells, then four cells, eight cells, and so on. Which of
the following statements best describes what happens during this process?

Answers

Answer options:

a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.

b.) chromosomes are divided evenly during cell division so that each new daughter cell has an equal share of the original set.

c.) chromosomes are stored in the original cell to direct the division of all daughter cells, which do not have their own chromosomes.

d.) chromosomes are randomly distributed during cell division so that some new cells have partial sets while others have complete sets.

Answer:

a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.

Explanation:

The cell divisions that allow organisms to grow are called mitosis. Before mitosis, all the DNA is duplicated.

Then, during mitosis, it condenses to form chromosomes. The identical chromosomes align in the centre of the cell. Then, they are equally distributed to among two daughter cells.

These two daughter cells each have a complete set of chromosomes. Each  daughter cell identical to the parent cell and to the other daughter cell.

O
D. DNA has thymine and RNA has uracil.

Answers

Answer:

Dna and RNA have a deoxribose sugar

The statement (D) is correct. DNA has thymine and RNA has uracil.

What is DNA and RNA?

DNA and RNA are both types of nucleic acids, large molecules that are made up of monomers called nucleotides. Nucleic acids are used to store genetic information, which the cell uses to make proteins.

Moreover, nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

Hence, DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

Does the plant use all wavelengths of light to carry out photosynthesis? Why does this make plants look green?

Answers

Answer:

Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

Which layer from Earth's atmosphere is convective in nature ?

It is the troposphere that is convective in nature. Troposphere means the region of mixing.

The mantle is  the most similar to sun's convection zone. Sun's convection zone is later  dominated by  the convection currents that carries energy outward to surface. Mantle is second layer of Earth.

The zone is not that  dense enough to  just use the  radiative transfer of  the  energy, infact ,  they uses the  thermal convection zones in just  other words then  it boils. Energy is  then carried out  through the  thermal columns to surface of sun and  later creates  out areas that are seen  as  the solar granulation and  the super granulation.

Who was Albert Einstien and what was he known for ?

Here ya go , Fivez and marcus UwU

Answers

Answer:

Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation [tex]e = mc^{2}[/tex] (Energy equals mass times the speed of light squared).

He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation [tex]e = mc^{2}[/tex].
