I'm pretty sure the answer would be A. Chromosomes contain one or more genes.
The correct option is 3.
Enzymes are biological catalysts which speed up the rate of biochemical reactions inside the cells. Enzymes are very specific in action and they require specific conditions called optimum conditions for them to function optimally.
When the optimum conditions are not met, an enzyme's activity will be lowered or totally stopped.
Conditions that affect the optimum activity of an enzyme include: temperature, pH level and regulatory activity of regulatory enzymes and hormones.
Answer:
Voltage-gated Ca2+ channels
Explanation:
Modulation of Ca+2 channel Epinephrine also causes an increase in cAMP that stimulates PKA that is protein kinase A, which in turn phosphorylates the voltage-gated Ca+2 channel that is the L channel. This phosphorylation results in a protein conformational change that enchances the channels activity.
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
options:
a) noninvasive
b) precise
c) inexpensive
d) easy
Answer:b) precise
Explanation: BMI(BODY MASS INDEX) is a very vital measurement tool for evaluating and the determining the level of Obesity of overweight of a person.
Body mass index is noninvasive, it is inexpensive and easy way of knowing how well the body weight and height is related to a person's well being.
It is calculated as follows; WEIGHT(KILOGRAMS)/SQUARE OF THE HEIGHT(METERS)
