Answer:
A. They do not use up any energy finding mates.
Explanation:
The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.
For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates
Therefore in the given case the correct option is A.
The correct answer is:
D
.Villi in the small intestine have thin-walled capillaries to make the absorption of nutrients more efficient.
Explanation:
The small intestines are well adjusted for absorbing nutrients during digestion by being very long, having villi and microvilli that enlarge surface area, using muscular contractions to move and mix food, and raising and housing digestive enzymes and bile that aid the breakdown of food. The inner surface of the small intestine is not flat but thrown into circular folds, which not only enhance surface area but aid in preparing the ingesta by acting as baffles. Villi: the mucosa makes multitudes of ridges which project into the lumen and are satisfied with epithelial cells.
The answer is K-selected.
The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent.
Cellular respiration is the process by which the body breaks down sugar like glucose, to release ATP, which is an energy storing molecule. This is how the body gets energy from food.
The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
K.E = ½ × 1324 × 20²
K.E = 264800J
Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
