b. epiglottis
c. bronchiole
d. laryngopharynx
Answer:
The correct answer is option c. "bronchiole".
Explanation:
The passage of airway within the lungs is known as bronchus. However, air exchange does not happen in the bronchus, it happens in small air sacs named alveoli. The smaller versions of the bronchus are known as the bronchiole, which branches further until it becomes the alveoli, the structure at which air exchange takes place.
B. both macroevolution and microevolution
C. macroevolution
Answer:
macroevolution
Explanation:
Answer: is odor
Explanation: As individuals age, their ability to identify and remember different types of odors declines due to changes in the olfactory system and the brain. Research consistently supports this phenomenon.
The dependent variable is the location of food.
The dependent variable in the given question is location of food. The question is asking whether kangaroos can remember the location of food in the absence of odor. The location of food is what is being measured and observed in the experiment, while the odor and kangaroos are referred to as independent variables.

I'm not sure though
After a human skin cell, which is made up of 46 chromosomes, undergoes mitosis, it divides into two new cells, each containing the same number of chromosomes as the original cell - 46.
A human skin cell, or a somatic cell, contains 46 chromosomes. This includes 22 homologous pairs and one pair of sex chromosomes, a configuration known as diploid (2n). When a somatic cell undergoes mitosis, which is a process of cellular division, it creates two identical daughter cells. Each of these new cells will contain 46 chromosomes, the same as the original cell, maintaining the diploid (2n) condition. This is because mitosis involves the replication of DNA, alignment of chromosomes at the metaphase plate, splitting of sister chromatids, and reformation of the nucleus, ensuring that the resultant cells have the same genetic composition as the parent cell.
