Mars2501 [29]3 years ago
6 0

Answer:

metabolism refers to all chemical reactions that allow to the cells carry out their functions

Explanation:

In a wide sense, the term metabolism refers to the chemical reactions that occur in the cells of a particular organism in order to sustain life. In a cell, the term metabolism can be delimited as all the chemical reactions inside the cell in order to carry out all cellular functions (e.g., growth, development, reproduction). Metabolic reactions can be divided into 1-catabolic reactions, which typically release energy and involve the breakdown of larger molecules into simpler ones, and 2-anabolic reactions, which typically require an input of energy stored in the chemical bonds of complex molecules.

A student's grade goes from a 95 to a 65 in 3 weeks. Calculate
steposvetlana [31]

-10grade/week

Explanation:

Given parameters:

Initial grade = 95grade

Final grade = 65grade

Time = 3weeks

Unknown parameter:

Rate of change of grade = ?

Solution:

Rate is defined as the change of a quantity with time.

 Rate of change of grade  = \frac{Final grade - Initial grade}{Time}

Rate of change of grade  = \frac{65 - 95}{3} = \frac{-30}{3}

Rate of change of grade = -10grade/week

The rate of change of the student's grade is -10grade/week. It implies that the grade of the student reduces by 10unit per week.

4. You have 263 mL of liquid mercury, what is the mass of mercury that you have? (Note:
xeze [42]
If we had 263 ml of mercury (volume) the density of the mercury is 13.55
g/cm”

Mass = Density x Volume (use image attached as guide)
Mass = 263 x 13.55 = 3563.65
Your mass should be 3563.65

What might happen if cells divide uncontrollably
ddd [48]
<span>When cells divide uncontrollably it causes things like mutation or cancer. This is because cancerous cells go through rapid cell division. They do not develop in the same way that healthy cells develop. </span>

An astronaut is in a sleeping bag attached to a wall. When astronauts sleep in space, they sleep in small cabins or in sleeping
Mnenie [13.5K]

Answer:

Free fall.

Explanation:

When astronauts sleep in space, they sleep in small cabins or in sleeping bags that are attached to the wall or ceiling of the station. Everything is weightless as there’s no gravity in space. So while sleeping there is a chance of floating around and bumping into things. Astronauts use sleeping bags that can be tethered to the wall or ceiling to solve this problem. Also the tethered sleeping bags provide a normal sleeping environment to the astronauts  as they can feel pressure on their back and head.  Their sleeping cabin is well ventilated as they can wake up with breathing trouble as a result of the inhalation of their own exhaled carbon dioxide which formed around their heads as a bubble. They use earplugs and a sleep mask to block the noise and light and can sleep vertically or horizontally. Compared to earth, sleeping is a bit different in space.

After decades of studying extraterrestrial organisms on Triton, you and your colleagues have developed a pretty good cladogram (
Nutka1998 [239]

Answer:

The effect might be due to the gene expression.

Explanation:

The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.
