Answer:
It is a test to check the protein's solubility.
Explanation:
Proteins have varying levels of solubility and it is necessary to carry out tests that prove in which aqueous media the proteins are more likely to have high levels of solubility. This facilitates the execution of scientific works that develop products that work with proteins.
The level of solubility of proteins depends on the distribution of the polar and nonpolar groups of this molecule.
The most common test is done by adding water and protein to a beaker. An example of this is done by adding part of egg albumin mixed with two parts of water.
explain how the biosphere facilities movement of water from the geosphere to the atomosphere.
Answer:
Explain how the biosphere facilitates movement of water from the geosphere to the atmosphere. The biosphere includes all living components of the Earth. ... Water from the plants is incorporated into the atmosphere through a process called transpiration, where water from the plant evaporates and enters the atmosphere.
Answer:
The biosphere includes all living components of the Earth. Plants, a part of the biosphere, pull water from the ground, part of the geosphere, for their use in the process of creating food.

Where should the biosphere label appear in the system model? Use reasoning to explain your answer.
Answer:
Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.
In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.
The biosphere label should be appeared in the system model that contains geological sphere of the earth.
What is biosphere?
It is the one of the sphere that comprise of the geological sphere of the earth like the geosphere, hydrosphere and atmosphere. In this, there should be the existance and the interaction of the living organism.
Here in the given model, there should be the human, fished, etc should be labeled as the biosphere rather than the atmosphere or without the atmosphere.

Which food is at a temperature that allows bacteria to grow well ? A) a roast at 125•F (52•c) B) hamburgers at 165•f (74•c) C) pork chops at 170•f (77•c) D) A steak at 180•f (82•c)
The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.

Explanation:
Is the widely accepted scientific theory that characteristics of a population may change over time, and that current species may gradually give rise to new species.
Answer:
Evolution theory
Explanation:
The evolution theory was developed by Darwin and it is a generally accepted theory that deals with gradual changes in the characteristics of organisms due to their quests to adapt to continuous changes in the environment.
As the environment of organisms keeps changing, the population of the organism keeps adjusting. Individuals that are able to adjust to the changes survive and are able to reproduce while the weak ones gradually die off from the population.
Hence, the entire characteristics of the population is changed with time as a result. The continuous changes sometimes lead to some species within the population giving rise to a new species entirely.

Glycogen is a polymer in animal tissues which stores extra sugar molecules until the animal needs them. What is the name
of the molecule found in plants that functions similarly?
O A. Glucose
O B. Cellulose
O C. Starch
O D. Lipids
Answer:
C. Starch
Explanation:
Functionally, both starch and glycogen are polysaccharide storage molecules for energy and both are intended to provide a supply for later use.
A. Glucose is incorrect because it is short term energy, in both plants and animals and is also a monosaccharide.
B. Cellulose is incorrect because, despite being a polysaccharide, it is mainly used for structure and support.
D. Lipids is incorrect because they store energy but it is for fat energy, not sugar. Lipids also have other uses such as structure and signaling, and insulation.

In a small population of Brazilian natives, the frequency of gene p, responsible for this disease, is 0.3. What must be the frequency of people who are heterozygous for this disease?
Answer:
Explanation:
According to hardy weinberg
p+q=1
p2+2pq+q2=1
p stands for the dominant genotype
q stands for recessive genotype
pq stands for population that are not homogenous i.e not the same
Given that p=0.3
P2=0.09
q=1-0.3= 0.7
q2=0.49
2pq= 2×0.3×0.7
=0.42
Therefore, the frequency of heterozygous population is 0.42
p2+2pq+q2
0.09+0.42+0.49 = 1

:
A flea and dog are an example of parasitism, because the flea irritates the dog's skin and feeds on its blood.
In a parasitic interaction, one organism benefits whereby the other one harmed. It is a positive - negative relationship. This interaction involves the interaction between the host and the parasite. The host is the bigger organism, here, the dog that is being harmed. The parasite is the flea causing the harm and benefiting from the relationship.
Certain bacteria live in the digestive tract of humans, and their relationship is an example of because mutualism the bacteria help humans to break down the food they eat.
In mutualism, the interaction is based on both organism deriving benefit from one another. Here, the bacteria gets its nourishment by breaking down human food. Human beings are able to digest the food better and are also nourished. A win-win situation is established.
Cattle egrets eat insects off the back of an elephant, which is an example of commensalism because the cattle egrets benefit without either harming or helping the elephants.
This relationship is known as commensalism in which one organism derives benefit. The other one derives no benefit and it is also not harmed in the process. The egrets feeds on the insects that are not harming the cattle.
