The changes over time in the inherited traits of a type of organism are ____.
A) growth
B) biogenesis
C) spontaneous generation
OD) evolution
The changes over time in the inherited traits of a type of organism are known as evolution of the species. Thus, the correct option is D.
What is Evolution?Evolution is change in the heritable characteristics of biological populations which are taking place over the successive generations. These characteristics are the expressions of different genes, which are passed on from the parents generation to their offspring during the time of reproduction.
Variation in the genetic material tends to exist within any given population as a result of the genetic mutations and recombination. Evolution in a species occurs when the evolutionary processes such as natural selection and genetic drift act on this variation in species, resulting in certain characteristics which are becoming more common or more rare within a population than other traits.
Therefore, the correct option is D.

How does RNA polymerase know where to start and stop making a strand of RNA?
Answer:
Each gene has a beginning and an end. At the beginning of each gene is a similar sequence that tells the RNA polymerase to start working. The same is true at the end of each gene where a specific sequence tells the RNA polymerase to stop transcription

d. The concentration of oxygen in the blood is the same as the concentration of carbon dioxide in the tissues.
e. The concentration of oxygen in the blood is higher than that in the tissues f. The concentration of oxygen in the blood is lower than that in the tissues 1
g. The concentration of oxygen in the blood is the same as that in the tissues.
Answer:
The answer is e
Explanation:
Oxygen moves due to diffusion, and the diffusion of oxygen occurs from higher concentration to lower concentration that is from the blood into the tissues

How are hydrogen bonds related to polarity?
Answer:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions
Explanation:
How is water traveling underground to lost Lake?
Answer: Water becomes the part of the aquifer.
Explanation:
Water from rain, snow fall, river, lakes, ponds, ocean, irrigation field, and from other sources become the part of the ground water or aquifer. The water seep into the soil or rocks and deposited as reservoir of water underground. The underground water when exposed to the surface can become the part of the lost lake or any other water body. Thus the source of lost lake can be determined this way by tracking the distance covered by the ground water.
Maja puts a hockey puck onto ice. After a while the temperature of the hockey puck decreases. What happens to the molecules of the hockey puck when the temperature of the puck decreases?
Answer: The energy of the molecules in the hockey puck decreases.
Explanation:
When the temperature of the hockey puck decreases, then the energy of the molecules in the hockey puck decreases as well.
In this scenario, when the temperature of the hockey puck decreases, then the hockey puck will gain heat molecules and the cold energy of the molecules that are in the hockey puck will reduce.

In an experiment determining the effects of antibiotics on the treatment of pneumonia in mice, two groups of mice with pneumonia are compared. One group, group A, receives no antibiotic, and the other group, group B, receives 10 mg/kg of body weight of a new antibiotic. Besides the administration of the antibiotic, there are no differences between the two groups of mice. What is the purpose of group A
Answer:
Group A is the control of the experiment
Explanation:
In an experiment, the control group is the group that does not receive any experimental treatment. The control groups are kept in the same condition as the experimental group except the variable being tested (independent variable).
In this question involving an experiment to determine the effects of antibiotics on the treatment of pneumonia in mice. Two groups of mice were employed. One of the groups (group A) received no antibiotic while the other group (group B) received 10 mg/kg of antibiotics. This means that GROUP A is the CONTROL GROUP of this experiment.
