Plutonic or intrusive igneous rocks form when it cools below the Earth's surface.
Igneous rocks form when it cools on the Earth's surface.
How is the rock formation process?They originate from the solidification of magma inside the Earth's crust or when lava comes out of the mantle, through a volcanic eruption. When magma cools slowly inside the crust, turning into rock, a process called intrusion occurs.
With this information, we can conclude that Igneous rock or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic and Intrusive, or plutonic, igneous rock forms when magma remains inside the Earth's crust where it cools and solidifies in chambers within pre-existing rock.

is asthma is cased by virus
Answer:
Explanation:
Asthma is characterized by spasmotic contraction of the smooth muscle of the airways, by increased production of an abnormally viscous mucus by bronchial mucous glands, and, in severe attacks, by airway obstruction from mucus that has accumulated in the bronchial tree. This results in a greater or lesser degree of difficulty in breathing. One approach to classifying asthma differentiates cases that occur with an identifiable antigen, in which antigens affect tissue cells sensitized by a specific antibody, and cases that occur without an identifiable antigen or specific antibody. The former condition is known as extrinsic asthma and the latter as intrinsic asthma. Extrinsic asthma commonly manifests first in childhood because the subject inherits an atopic characteristic: the serum contains specific antigens to pollens, mold spores, animal proteins of different kinds, and substances from a variety of insects, particularly cockroaches and mites that occur in house dust. Exacerbation of extrinsic asthma is precipitated by contact with any of the substances to which sensitization has occurred; airway obstruction is often worse in the early hours of the morning. The other form of asthma, intrinsic, may develop at any age, and there may be no evidence of specific antigens. Persons with intrinsic asthma experience attacks of airway obstruction unrelated to seasonal changes, although it seems likely that the airway obstruction may be triggered by infections, which are assumed to be viral in many cases. Asthma attacks may be precipitated by food. For example, in small children, sensitivity to milk may stimulate an attack, and, in some adults, sensitivity to sulfite compounds found in some foods and wine may stimulate an attack. A subgroup of asthmatics are so sensitive to aspirin (acetylsalicylic acid) that ingestion of this chemical may lead to a life-threatening attack.
Answer:
No, not necessarily
Explanation:
Asthma isn't necessarily caused by a virus or a pathogen. It can be genetic or environmental, meaning that it can be passed down through family members, or it can result from an environmental factor, such as allergies or poor air quality.

Can someone please help me understand how to get the answer to question #2?
In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and f is the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (Ff) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (f) and 70% (0.7) are dominant (F). 1. Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation. Be sure to show me your work. 2. You have collected data on the observed genotype frequencies of the next generation. They are 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not?
Answer:
The traits are only slightly evolving due to the small changes in the genotypic and allelic frequencies between both generations.
Below is a more detailed explanation. I hope it's understandable. Please reach out if you need clarification <3
The frequency of the recombinant, dominant, and recessive genotypes is 0.42, 0.49 and 0.9 respectively.
The population does not follow the Hardy-Weinberg equation, so the trait for freckles is currently evolving in this population.
According to the Hardy-Weinberg equilibrium, if no unfavorable influences exist, genetic variation in a population will remain stable from one generation to the next.
1. To find out the frequency of the genotypes in the population, we will use the Hardy-Weinberg equation,
We know the probability of the alleles, F = 0.7 and f = 0.3.
Now,
Frequency of FF = [tex]p^{2}[/tex] [tex]= 0.7^{2} = 0.49[/tex]
Frequency of ff = [tex]q^{2} = 0.3^{2} = 0.9[/tex]
Frequency of Ff = [tex]2*p*q = 2*0.7*0.3 = 0.42[/tex]
2. For the next generation, the given frequencies are,
Frequency of FF = 60% or 0.6 = [tex]p^{2}[/tex]
Frequency of Ff = 30% or 0.3 = [tex]2*p*q[/tex]
Frequency of ff = 10% or 0.1 = [tex]q^{2}[/tex]
For Hardy-Weinberg equilibrium,
[tex]p^{2} + q^{2} + 2*p*q = 1[/tex] or [tex](p^{2} + q^{2} ) = 1[/tex]
[tex]0.6 + 0.1 + 2 * 0.6 * 0.1 = 0.0.82 \neq 1[/tex]
Hence, the frequency of occurrence in dominant, recessive, and recombinant type is 0.49, 0.42 and 0.9.
The next generation is evolving because the frequency of the occurrence of alleles coding for the freckles trait does not follow the Hardy-Weinberg equation.

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.
What is Active transport?Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.
During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.
But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

What two processes make up cell division
Answer:
Mitosis and Meiosis
How does cell division work?The cell that is dividing in a cell division process is referred to as the parent cell. Upon division, the parent cell produces two daughter cells. The next phase, known as the cell cycle, involves repeating the procedure.
Cells control their division by exchanging chemical signals via unique proteins called cyclins with one another. These signals function as switches that inform cells when to begin dividing and afterwards when to stop. For you to develop and for your wounds to heal, cells must divide. Cells must also cease dividing at the appropriate moment. Cancer can result from a cell's inability to stop dividing when it should, which is a condition known as cell division failure.
Now, how do cells divide?
There are two ways for cells to divide, depending on the type: mitosis and meiosis. Each of these strategies for cell division has unique qualities. A single cell splits into two identical cells with the same number of chromosomes during mitosis, which is one of the major distinctions between the two processes. Cell division of this kind is beneficial for fundamental development, repair, and maintenance. A cell divides into four cells during meiosis, each of which has half as many chromosomes. To promote genetic variety and sexual reproduction, the number of chromosomes must be cut in half.
Answer:
Mitosis and Meiosis
Explanation:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.

A father has red-green colorblindness, meaning his X chromosome carries the X-linked disorder. His wife is not color blind, nor is she a carrier.
What are the odds that their daughter is a carrier for red-green colorblindness? Set up a Punnet Square to answer the question.
Answer:
100% carrier daughter
Explanation:
Remember,
---> individuals with XX are always female
---> individuals with XY are always male
Therefore, if all of the female offspring are carriers, this means the odds that their daughter is a carrier is 100%.
1No.Answer:- The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.
2No.Answer:- Each daughter has a 50% chance of being a carrier and each son has a 50% chance of being color blind. The daughters who are carriers can have color blind sons with the same logic.
