Answer:
The correct answer is - To dissolve the cell and nuclear membranes and release the DNA.
Explanation:
The major function of the detergent in DNA extraction is to dissolve the cell and cellular membranes. It can increase the membrane permeability by pulling apart lipids and proteins that are components of the nuclear and cellular membrane and lyse the cell, from which we want to extract the DNA.
Detergents cause pores in the cell membranes and once these membranes are completely lysed the DNA is released from the cell. It is similar to detergents removes fat (lipids) from dishes.
In the experiment, "Do white cats eat more than black cats?" the independent variable would be:
the color of the cat.
how much each cat weighs.
how much food each cat eats.
the temperature of the food.
In the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.
What is an Independent variable?An independent variable may be defined as a type of variable that significantly and effectively stands alone and isn't changed by the other variables you are trying to measure. The independent variable is the cause. Its value is independent of other variables in your study.
According to the context of this question, the color of the cat would not depend on how much food a particular type of cat eats. This will depend on the nature and diet of the cat along with its physiology and pattern. So, the color of the cat would be thought to be the independent variable in the experiment because it does not make any sense in the eating cat.
Therefore, in the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.

Describe the components of a buffer and the role each
plays in helping maintain a constant pH.
The components of a buffer and the role each plays in helping maintain a constant pH are acid-base and its salt.
What is a buffer?
A weak acid and its conjugate base, or a weak base and its conjugate acid, make form a buffer solution. When strong acids or bases are added, the pH balance of the two components remains stable.
A buffer is a solution that withstands any pH change when a little amount of both an acid and a base is added to it. The salt of the acid or base must be present for a solution to qualify as a buffer.
For an acidic buffer, acid and its salt with a strong or weak base are necessary ingredients. As an illustration, consider an acetic acid and sodium acetate solution.
For a basic buffer, a base salt with a strong or weak acid is a necessary component.
Thus, the components of a buffer are acid, base, and salts.

When thinking about genotypes and phenotypes, which is the cause and which is the effect?
Answer:
A particular genotype does not necessarily guarantee a particular phenotype. Understanding what factors can change this expression is quite complex.. What is what i believe that above statement meant.
Explanation:
Error is the stochastic variation associated with a particular observation of the phenotype (and is managed by use of replication and and appropriate experimental design). The phenotype is the result not only of the average effect of the different alleles at a given locus across test units and across environments, but is impacted by the interaction between the different alleles and the environments (including genetic backgrounds) in which they are evaluated. Phenotype is not simply the sum of the genotype effect and the environment effect, as indicated in the mathematical formula that you provide.

if your answer is right you l get brainly
Answer:
Lupus refers to autoimmune disease in which the immune system of the body attacks its normal and healthy tissue instead of virus and bacteria. Symptoms of this disease include inflammation, swelling, and damage to the joints, skin, kidneys, heart, and lungs etc. The main cause of this disease is the environment that triggers Lupus. Chemotherapy and medications such as Nonsteroidal anti-inflammatory drugs and Antimalarial drugs etc are used for its treatment. Due to the disease's complex nature, it is often called "the of 1000 faces". In the united states there are about 16000 new cases of lupus every year. There are different kinds of lupus. This article will focus mainly on systemic lupus erythematosus (SLE), but other types include discoid, drug-induced, and neonatal lupus. Currently there is no cure for lupus, but the symptoms can be managed with care. The treatment aims to manage and prevent flare ups. The exact treatment will depend on how lupus affects the individual. Without treatment, flares can occur that may have life-threatening consequences.

What human behavior was the cause of the Nipah virus outbreak in Bangladesh? How did scientists determine this?
Answer:
Humans drinking raw date palm sap was the cause of the Nipah virus outbreak in Bangladesh. Scientists found Nipah virus in bat excretions and discovered that bats were contaminating date palm juice with their excretions (saliva, urine).
Explanation:
Nipah virus can spread to people from:
1) Direct contact with infected animals, such as bats or pigs, or their body fluids (such as blood, urine or saliva).
2) Consuming food products that have been contaminated by body fluids of infected animals (such as palm sap or fruit contaminated by an infected bat).

What family of KBOs does Orcus belong to?
Answer:
Pluto
Explanation:
Orcus is a plutino, a trans-Neptunian object that is locked in a 2:3 resonance with the ice giant Neptune, making two revolutions around the sun to every three of Neptunes. This is much as pluto, except that the phase of Orcus's orbit is opposite from Pluto's: Orcus is at aphelion when pluto is at aphelion when Pluto is at perihelion and vice versa. This was a major consideration in selecting its name, as deity Orcus was the Etruscan equivalent of the Roman Pluto, and later becamean alternate name for Pluto
Family of KBOs orcuas belongs to plutino, it is a plutino object revolves around the sun.
What is Family of KBOs?Orcus is a plutino, a trans-Neptunian object that revolves about the sun twice as often as Neptune and is locked in a 2:3 resonance with it.
This is quite similar to Pluto, but Orcus's orbital phase is the opposite of Pluto's, Orcus is at aphelion while Pluto is at perihelion, and vice versa.
This was a key factor in naming it since the deity Orcus was the Etruscan counterpart to the Roman Pluto and eventually developed into a different name for Pluto.
Therefore, revolves around the sun twice as often as Neptune is the plutino is a orcus in the family of KBOs.
