Which of the following is an example of the endocrine system maintaining homeostasis?
A. Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response.
B. Discharging an excessive amount of hormones in the blood and not sending a signal to stop production.
C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low.
D. Using sense organs to get information about the outside world and direct an appropriate body response release.
Ans.
Endocrine system is a body system that consists of hormones, a group of glands, and secret those hormones into bloodstream directly to regulate the functions of target tissues or organs.
Endocrine system maintains homoestasis by regulating temperature of the body. When there is a rise in body temperature, the endocrine system sends information from hypothalamus to muscles, glands, organs, and nervous system that help to return the temperature into normal level.
Thus, the correct answer is option). 'passing information about body temperature from the hypothalamus to the sweat glands or muscles.'

How will the dam most likely affect the ecosystem around the river?
Answer: Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.

What Propelled transatlantic trade when sailing was the only option for sea travel. 1. Convections 2.trade wins 3. Jet streams
Answer:
1. Convections
Convections propelled transatlantic trade when sailing was the only option for sea travel. The correct option is 1.
What is convection?Convection is a method of moving heat that is also known as a heat transfer mechanism.
When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.
Heat transfer between objects occurs through direct contact in conduction. Heat transfer occurs within the fluid during convection.
Heat transfer in radiation occurs via electromagnetic waves rather than particles. Heat transfer occurs as a result of temperature differences.
The trade winds, also known as easterlies, are the permanent east-to-west winds that blow in the Earth's equatorial region. When sailing was the only option for sea travel, convections propelled transatlantic trade.
Thus, the correct option is 1.

Explanation:
Sea anemones can reproduce sexually or asexually. What would be the most likely advantage a sea anemone would have to reproduce sexually over reproducing asexually?
Answer:
Re-producing sexually will allow the sea anemones to give their offspring a more diverse gene pool and can mitigate the risks of a genetic disorder being spread to the offspring because the bad gene has a higher chance become recessive if the gene of the anemone it mates with is more dominant (meaning it wouldn't allow the "bad" gene to show in the offspring) whereas otherwise, the offspring would have the same issues the mother did (assuming it had a bad gene to begin with).

How does lake effect snow affect the human population living in New York? Support your claim with evidence from the article. Then, explain why the evidence supports your claim. You need a paragraph (5-8 complete sentences).
Answer:
This causes some lake water to evaporate into the air and warm it. This warmer, wetter air rises and cools as it moves away from the lake. When it cools, it dumps all that moisture on the ground. If it's cold enough, that moisture becomes snow.

The effect of the lake effect snow is to become difficult to travel, the snow cover their cars and other things.
What is the lake effect snow?Lake effect snow occurs when cold, below-freezing air travel over a lake's warmer water.
As a result, some lake water evaporates, warming the air.
Then, the warm air moves away and after cooling it become snow.
The areas in effect by lake effect snow is called Snowbelt.

heres what i found:To understand chromatin, it is helpful to first consider chromosomes. Chromosomes are structures within the nucleus that are made up of DNA, the hereditary material. In prokaryotes, DNA is organized into a single circular chromosome. In eukaryotes, chromosomes are linear structures. Every eukaryotic species has a specific number of chromosomes in the nuclei of its body’s cells. For example, in humans, the chromosome number is 46, while in fruit flies, it is eight. Chromosomes are only visible and distinguishable from one another when the cell is getting ready to divide. When the cell is in the growth and maintenance phases of its life cycle, proteins are attached to chromosomes, and they resemble an unwound, jumbled bunch of threads. These unwound protein-chromosome complexes are called chromatin (Figure 3); chromatin describes the material that makes up the chromosomes both when condensed and decondensed. We will focus on chromatin and chromosomes in greater detail later.
