The answer is................................................C
Answer:
Perma Dorji (PD) and Kesan Choden (KC) are children.
If the number of brother PD has is X, the number of sisters she has is 3X
If the number of brothers KC has is 3X, then the number of sisters she has is 3X-2
Explanation:
The total number of children (brothers and sisters) therefore are:
PDs siblings = 3X+X plus
KCs siblings = 3X2
= 3X+X +3X-2
=6x-2
Let's assume that X is 1, therefore the number of siblings equals
6(1)-2
= 4
Don't forget the PD and KC are also children.
Therefore, the total children in the family is equals to 6
Cheers!
The answer is A: Double Helix
Answer: The majority of animals on our planet, about 95 percent, do not possess a true backbone and are called invertebrates. It's common knowledge that vertebrates like humans have a complex nervous system that reacts to stimuli, but much less is known about invertebrates like shrimp and insects. While it's somewhat different from that of vertebrates, shrimp do have a central nervous system comprised of four main parts.
Explanation:
Gender, age and body weight are the three factors.
<h3>What are the effects of gender, age and body weight on energy expenditure?</h3>
Body weight:
Energy consumption while at rest is determined by body size and weight. Due to the higher maintenance costs associated with a larger body, a heavier person has a higher resting energy requirement. The most unpredictable part of overall energy expenditure is activity-induced energy expenditure. Since larger subjects' activity energy expenditure is not higher in proportion to the expense of moving with a higher body weight, smaller and leaner subjects often move more. As a result of changes in body size and body composition, eating causes variations in energy expenditure.
Gender:
In comparison to girls of the same size and age, adult males frequently have 10–20 percent more muscle mass. Because muscle burns more calories than fat, men have greater basal metabolic rates (BMR). As a result, men need 5–10% more energy than women.
Age:
Compared to adults, children and adolescents require more energy for growth and development. As people age, their body composition changes and their energy needs decrease, resulting in a decrease in BMR. As people age, many of them become less active.
