Answer:
D. By decreasing the activation energy of a reaction
Explanation:
B. to make cellulose in the cell walls
1. it <span>supports muscles and tissue
2.it also </span><span>protects the vital organs
3. </span>The skeleton gives the body its shape, which changes with growth. In
addition to determining characteristics such as height and the size of
the hands and feet, stable body shape enables essential functions. For
example, a stable rib cage and spine enable the lungs to fully inflate
when breathing. Conditions such as osteoporosis of the spine and broken
ribs can alter the shape of the chest and impair this vital body
function.

5.Larger bones contain bone marrow, a spongy tissue inside the bones.
There are two main types of marrow, red and yellow. Red marrow is
responsible for production of all of the body's red blood cells and many
of its white blood cells. Red blood cells are produced at an average
rate of approximately 200 million per day. These cells carry
life-sustaining oxygen to the body tissues.
In adults, red marrow is found primarily in the breastbone, hips, ribs,
skull, spinal bones and at the end of long bones of the arms and legs.
Several types of white blood cells, which protect the body from
infections, are also produced in red bone marrow. Yellow bone marrow
contains primary fat cells but can transform into red marrow if the body
needs to increase blood cell production, such as if anemia develops
The choices can be found elsewhere and as follows:
<span>(1.) synthesis
(2.) digestion
(3.) excretion
(4.) respiration
</span>
I believe the correct answer is option 1. <span>As a direct result of synthesis process, a plant makes a variety of chemical substances such as poisons,drugs, and flavorings. Hope this answers the question.</span>
<span>The study of heredity, or how the characteristics of living things are transmitted from one generation to the next. Every living thing contains the genetic material that makes up DNA molecules. This material is passed on when organisms reproduce. The basic unit of heredity is the gene</span>
