What kind of rock is this?
igneous
Where would this rock most likely be formed?
To which group of rocks would this rock belong?
Rocks can be classified based on texture. The
size of the grains in a rock affects its texture.
Coarse-grained rocks have large grains, and fine-
grained rocks have small grains.
Rocks formed from magma under Earth's surface
have larger grains than rocks formed from lava
on Earth's surface. This is because magma cools
slower underneath the ground than it does above
ground.

Answer:

D) bilayer membranes

Explanation:

Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.

Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

i hope it helps you

The DNA stands for deoxyribose nucleic acid, it has all the information required for the proper functioning of the human body.

The correct answer is B

The process of the formation of protein from the mRNA is called translation. it requires:-

The mRNA has the introns and the exons in it. Exons are the coding part of the DNA while the introns are the non-coding part and it does not have any specific functions.

Hence, the correct option is B that is Introns do not have any specific function.

Answer:

a) Presencia de un catalizador

Explanation:

Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.

Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.

Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.

La evidencia de que ha tenido lugar un cambio químico incluye

1) La formación de un precipitado a partir de la mezcla de sustancias.

2) Un cambio en el color de las sustancias.

3) Un cambio en el olfato (que desprende un olor) o en el sabor.

4) La sustancia produce luz (brilla)

5) El volumen total cambia

6) Cambio de temperatura (la mezcla se calienta o enfría)

Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.

Answer:

Carotenoids have two important functions in plants. First, they can contribute to photosynthesis. They do this by transferring some of the light energy they absorb to chlorophylls, which then use this energy to drive photosynthesis. Second, they can protect plants which are over-exposed to sunlight. but the letter answer I don't know

The benefit of a plant having Chlorophyll and Carotenoids is that plant can absorb energy from multiple wavelengths at once. Option A is the right answer.

Chlorophyll is the green pigment that is responsible for the green color in the leaves of plants. Carotenoid on the other hand is a yellow, orange, and red color pigment that is produced in plants, algae, and some other forms of bacteria.

External Respiration.

Explanation:

External Respiration is the type of respiration in which exchanges of gases occurs between the lungs and the bloodstream i.e. pulmonary capillaries. Inside the lungs, oxygen is loaded into the hemoglobin and carbon dioxide waste is unloaded, this process is called external respiration. This respiratory process takes place through the help of hundreds of millions of microscopic alveoli.

Answer:

A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

Cloudlets, also known as altocumulus clouds, are tiny mid-level layers or patches of clouds that are most often seen as spherical clusters. However, since there are so many different types of altocumulus, they may take on a variety of forms.

Indicators of convection, or increasing heat, in the atmosphere include altocumulus clouds. Warm air rises into the sky, where it cools and condenses nearby water droplets to create the cloud formations that we see from the ground.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.

Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

The size of the largest artery through which the blood flows, known as aorta

Answer:

Option A. Air pollution can cause water pollution.

Explanation:

Substances can permeate into the water from the air.

Water gets polluted by many causes, but a major cause is the air, and chemicals introduced can cause water pollution, hence option a and c is correct.

Water pollution is described as the contamination of water sources by chemicals that render the water unsafe for drinking, cooking, cleaning, swimming, and other uses.

Chemicals, garbage, germs, and parasites all are types of pollutants. All types of pollutants eventually end up in the water. It has the possibility of contaminating drinking water, contributing to waterborne diseases.

Water pollution has an impact on the ecosystem as well because it could induce eutrophication. This can harm fish and other aquatic organisms.

Therefore chemicals and air both pollute the water, then through into the water bodies, hence a and c is the correct option.
