Answer 1

So I believe these are the questions to go with the statement based on the info given to make a question (hypothesis) , I believe it’s “A” because based on the statement it give details about the one of them being able to drink water that contains fluoride salts and the other doesn’t drink water with fluoride salt . And we don’t know where they live , or even who drinks the fluoride salts or no so “A” is a appropriate question to give . And the numerical data part can also include the people who lives in their neighborhoods .

Hope this helps☺️

How does a single fertilized egg cell develop into all the different cells of your body? Use cell division and differentiation in your answer.

Answers

Answer:

Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

Explanation:

- Eijiro <3

A zygote is formed when an egg is fertilized. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.

What is Differentiation?

This is the process in which cells acquire different structure and function from one another to form distinct cell types.

When a zygote is formed, cell division takes place which helps to trigger differentiation of cells.

Why does the bronchioles get smaller and smaller before they reach the alveoli?

Answers

Answer: Parasympathetic stimulation causes bronchoconstriction while sympathetic stimulation causes bronchodilation. During an asthma attack, the muscles that encircle the airway tighten or constrict, limiting the flow of air to and from the lungs.

Explanation: i hope this answers your question and i have a awesome marvelous day.

Answer:

In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways -the smallest, called bronchioles lead to tiny air sacs (alveoli)

the bronchiole end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood, after absorbing oxygen, the blood leaves the lungs and is carried to the heart, the blood then is pumped through your body to provide oxygen to the cells of your tissues and organs.

What are the two factors that determine the boundaries of a biome?

A. altitude

and

D. latitude

Explanation:

hope this helps! :D

The two factors that determine the boundaries of a biome are temperature and precipitation, which are the second and third options, as they help to shape the unique features of each biome.

What is the significance of the precipitation and temperature?

Temperature plays a key role in determining the type of vegetation, such as in colder regions where low temperatures limit the types of plants that can grow, while in warmer regions the growth of tropical rainforests is seen. Precipitation plays an important role too, as in areas with high levels of precipitation, such as tropical rainforests, dense vegetation is seen, and in dry regions with low levels of precipitation, deserts are seen.

Hence, the two factors that determine the boundaries of a biome are temperature and precipitation, which are the second and third options, as they help to shape the unique features of each biome.

His study of the experimental method

Answers

Answer: The study of plant varieties.

Explanation:

This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.

Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.

He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.

13. Which of the following shows the correct relationship between warm
ocean water and its movement? *

Answers

Answer: B

Explanation:

The following that shows the correct relationship between warm ocean water and its movement is:

A. The density increases and the movement rises

Warm ocean water is the condition in which the temperature of the ocean is warm. This in turn affects climatic conditions as it also has an effect on the marine ecosystem.

As a result of the temperature, warm water usually stays at the horizon of the ocean and when there is a joining of the cold water and the warm water, then there is a change in density as it increases while the movement of the water rises.

This phenomena occurs as a result of convection and the movement changes because warm water is less dense. The Indian Ocean is the warmest ocean in the world.

Therefore, the correct answer is option A

Answers

Answer:

Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. ... It is because density in an intensive property of matter. So they are not considered properties.
