Answer:

evacuate all wildlife from the bay

Explanation:

Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.

However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.

Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.

oksian1 [2.3K]

The process of cellular respiration is achieved in plants by the process of photosynthesis. The energy from glucose is derived in this process. The steps of the cellular respiration includes the glycolysis, the kreb's cycle, and the oxidative phosphorylation. During this process, the proton concentration builds in the thylakoid space of the plant cell.

a 24 kg rock containing 3,528 j of potential energy rests upon the edge of a cliff how tall is the cliff
GenaCL600 [577]
Potential gravitational energy is computed with the formula:

PEgrav=mgh

Where:
PEgrav = Potential gravitation energy (J)
m = mass (kg)
h = height (m)
g = acceleration due to gravity (9.8m/s^2) 

Take note that acceleration due to gravity is a constant. 

All you need to do is put in what you know and solve for what you don't know. So your given is the following:
PEgrav = 3,528J
m = 24 kg
g = 9.8 m/s^2
Put that into your formula:
PEgrav=mgh
3,528J = (24kg)(9.8m/s^{2})(h)
3,528J = (235.2kg.m/s^{2})(h)
\frac{3,528J}{235.2kg.m/s^{2}} = h
15m=h

The height of the cliff is 15m.

Zarrin [17]

Answer:

<h2>A</h2>

Explanation:

1. As given, the of a strand DNA contain sequence;

A-T-G-C-C-A-T-C-G-G-T-A,

2. After exposure to UV light, the strand contain the bases;

A-T-G-G*-C-C-A-T-C-G-G-T-A,

3. By comparing both the strands, we find that, the strand of DNA after exposure to UV contain extra G nucleotide between G and C, which is resulted by an insertion.

So we can say that, a new base has been inserted.

Q1.2. Suppose you decide to design an experiment
Solnce55 [7]

Answer:

The correct answer is :

Independent variable: study music.

Dependent  variable: test performance.

Explanation:

Independent variable in a experiment is a variable or a factor that is manipulated or changed in a particular experiment to see its the effect on dependent variable of this change. In this case classical music is variable as it is manipulated to see if it has any effect on studying.

Dependent variable is a variable which is measured in experiment to find the result and affected by the independent variable. In this case testing the performance of subject is dependent variable as it is being measured and affected by classical music.

Thus, the correct answer is: Independent variable: study music.

Dependent  variable: test performance.
