At the top of the body of a water, there is a lot of light from the sun, which also means a lot of solar energy. This allows for a fruitful photosynthesis.

In contrast, at the bottom of the water, there isn't as much, or sometimes any, sun light. Because of this the organisms at the bottom of the body of  water

Which of the following objects will exert the greatest gravitational force on a box, if the distance between them stays the same
Mumz [18]

Answer:

D). 8 kg mass

Explanation:

Acceleration of Falling Objects

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system. ... The stronger the pull of gravity on an object, the greater its weight.

A researcher synthesizes a new molecule called inhibitor X that inhibits the activity of phosphofructokinase (PFK), the enzyme t
Oduvanchick [21]

Answer : The dissociation constant of the PFK‑inhibitor complex is, 5 µM

Explanation :

The expression for reversible competitive inhibition when apparent Km affected by addition of the inhibitor is:

K_m_a=K_m[1+\frac{I}{K_i}]

where,

K_m_a = apparent value = 52 µM

K_m = Michaelis–Menten constant = 40 µM

I = inhibitor concentration = 1.5 µM

K_i = dissociation constant of the PFK‑inhibitor complex

Now put all the given values in the above formula, we get:

52\mu M=40\mu M[1+\frac{1.5\mu M}{K_i}]

K_i=5\mu M

Therefore, the dissociation constant of the PFK‑inhibitor complex is, 5 µM

<h2>The answer would be A.</h2>

When there are <em>multiple convection cells in each hemisphere</em>, something called <u>"The Coriolis effect"</u> happens. The defination is basically that the Earth rotates perpendicular to it's axis which is answer A.

Hope this helps!

ANSWER: The completion of the Human Genome Project

EXPLANATION:

Human Genome Project (HGP) was completed in April, 2003. Genome varies from one individual to another.

The project involved mapping and sequencing of some people and in other to get each chromosome full sequence in individuals.

However, at the beginning of this project, concerns like ownership and privacy of personal genetic information began to spring up. People are afraid that employers may have access to their genetic information and would reject persons with health issues indicated by their unique genes and health insurance companies may also not provide insurance to people that have deficiency.

In the view of this concern, the United States in 1996 passed the Health Insurance Portability and Accountability Act (HIPAA) which guides against the non-consensual and unauthorized release of health information of individuals.

Sergio039 [100]

Answer:

Both studies support the concept that species operate within a narrow optimum temperature range and are coupled to enzymatic activity.

Explanation:

The studies shown in the question above started from the same concept to establish the scientific experiment and had the same objective related to the investigation as temperature changes in the environment where these organisms live influences the enzymatic activity and, therefore, the functioning of their organism, being able to including modifying the environment around them. In summary, we can say that the studies sought to support the concept that species operate within a narrow range of optimal temperature and are coupled with enzymatic activity.
