Biology

4 0

Answer:

Option D

Explanation:

If an aspartic acid were present in the interior of a globular protein, it would most likely change the conformation of the protein, maybe changing its shape and ultimately its function. To ensure compactness of the interior, hydrophobic amino acid are mainly found in the interior of globular proteins. This acid can be deprotonated and become negatively charged if the surrounding solution's pH is raised changing their isoelectric points.

1) B
    (I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition

2) D
    Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.

3) A

4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.

You are doing an experiment involving antibiotic resistance in your study bacteria. This organism grows well on LB - Miller agar
KiRa [710]

Answer:

See the answer below

Explanation:

The stock solution of Gentamycin has a concentration of 5 mg/ml while each plate needs to contain 50 micrograms/ml of Gentamycin.

5 mg/ml = 5000 micrograms/ml

There is a need to dilute the stock antibiotic solution in order to arrive at 50 micrograms/ml. Using the dilution principle;

m1v1 = m2v2

5000 x 1 = 50 x v2

v2 = 5000/50 = 1000 ml

<em>Hence, in order to prepare 50 micrograms/ml, 1 ml of the stock Gentamycin should be taken and diluted with 999 ml of distilled sterilized water. 1 ml of the diluted Gentamycin will then be added to each agar plate while they are still in the molten form at a warm temperature.</em>

Failure in a particular structure of the heart tends to cause a backup of blood in the lungs, known as pulmonary congestive hear
xeze [42]

Answer:

Left ventricle.

Explanation:

Human heart is divided into four chambers - two auricles and two ventricles. Heart acts as the pumping organ and carries both oxygenated and deoxygenated blood in the right and left ventricles.

The failure of functioning of any chamber of heart may cause a particular disease in the individuals. The pulmonary congestive heart failure occurs due to the failure of the left ventricles of the heart. The left ventricle carries blood from heart to the body tissues, its failure leads to the backup of blood in the lungs.

Thus, the answer is left ventricle.
