Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. mc012-1.jpg Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?A)fertilization,(B)independent assortment,(C)crossing over, (D)chromosome replication

Answers

Answer 1
Answer: Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome

How would an injury in the central nervous system affect the peripheral nervous system? The peripheral nervous system would be prevented from sending information from stimuli receivers. The peripheral nervous system would not be able to process the information that it received from the stimuli receivers. The peripheral nervous system would block information from the central nervous system. The peripheral nervous system would have no information to send to the muscles and glands.

What is the difference between food chains and food webs? Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem. About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level. Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.

Answers

Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

What is food chain?

Food chain shows the relationship between organisms by the food they eat.

What is food web?

A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.

Difference between food chain and food web

Food webs show interconnection of food chains about the different animals in an ecosystem and different energy transfer processes.

Thus, food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

Answer:

Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

Explanation:

Unlike food chains, food webs show more detailed information about the different animals in an ecosystem and show multiple energy transfers to different animals from the same sources.

Suppose you are in the southern hemisphere during the month of December what would happen to the amount of sunlight as you travel south

Answers

The amount of sunlight would increase because the northern hemisphere is shifted up during winter. The southern hemisphere would be closer to the sun allowing more sunlight during the daytime.

The heart pumps harder and blood pressure rises during a fight-or-flight response. This response is due toa. thyroxine secreted by the thyroid gland.
b. adrenaline secreted by the adrenal glands.
c. insulin secreted by the pancreas.
d. oxytocin secreted by the pituitary gland.

Answers

The correct answer is letter b. adrenaline secreted by the adrenal glands.
The heart pumps harder and blood pressure rises during a fight-or-flight response. This response is due to adrenaline secreted by the adrenal glands. Adrenaline is a substance that is released in the body of a person who is feeling a strong emotion.

Which of the following examples best illustrates sensory interaction? A. Julie loves chicken noodle soup, but her cold is making it taste bland. B. Michael was surprised to find that he likes the taste of rare steak. C. Alyssa loves the smell and taste of her mother’s homemade apple pie. D. Eli thought the fish smelled great but tasted awful.

Answers

Answer: A. Julie loves chicken noodle soup, but her cold is making it taste bland.

Sensory interaction is the interaction among various sense organs of the body. It depicts how one sense organ influence the response from other sense organ. Taste and smell are examples of senses which are dependent on each other and can influence the response generated by external stimuli.  For example, food tastes are bland when a person is not able to inhale it's smell. Julie loves chicken noodle soup, but her cold is making it taste bland. Here, the taste of noodle depends upon smell of food as, Julie is not able to inhale the smell of food therefore, the taste is bland. Hence, this illustrates the best example for sensory interaction.
