A solution of one part of egg albumen mixed with two parts of water in a test tube is used to test for what?

Answers

Answer 1

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.

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)

Answers

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.

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.

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?

Answers

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

of the molecule found in plants that functions similarly?
O A. Glucose
O B. Cellulose
O C. Starch

Answers

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.

starch is the correct answer i think.

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.

Answers

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.
