How have freshwater and salt water fish adapted to deal with osmosis in their respective environments?
Answer:
Salt water fish are perfectly adapted to their salty environment and need osmosis to live. The replacement fluid taken on to replace the lost water is desalinated by a process known as diffusion. Diffusion allows fish to live in a state of constant osmosis

I'm in 9th grade going into 10th should I take chemistry or geoscience?
and online or in-person
Answer:
I am honestly having the same questions. I think which one sounds the most for your level or onto collage applications! Now I was thinking about online for some people it's easy. But it's easily distracted. You have more freedom to roam the internet. Scroll through Insta. Or play video games. Now that seems really awesome. But my grandma says 9th grade is the most important year. It determines whether if you need help or if you fail you spend the res of your years catching up. I also am going into 10th and these words are scary.
Explanation:
I don't want to go to school because I feel once the friends I made online see me.. They will change their minds.. But even though I know going in person where I pay attention better is the best shot.

Approximately time passes between B and F
Answer:
14 days
Explanation:
It takes 27 days for the moon to make a full rotation around the earth. Because half the of the rotation around the earth has been made, half 27. Half of 27 is 13.5, so the time between B and F is approximately 14 days.
Using this information and rge geologic time scale above, choose the period in which fishes with jaws first appeared.
A. Jurassic

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA
The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.
What is mRNA transcription?Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.
The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.
The DNA strand: ATGGCACCTTAC
The mRNA sequence will be: UACCGUGGAAUG
Therefore, option A. UACCGUGGAAUG is the mRNA transcript.

How do the organs of the excretory system work together to eliminate potentially harmful wastes from the body?
Answer:
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

On the surface of a plant's roots are thin projections called root hairs. Which of the following best describes the purpose of these root hairs?
They provide protection for the growing roots.
They help anchor the plant to the soil to make it sturdier
They store excess sugar produced during photosynthesis.
They allow for an increase in surface area so more water and nutrients can be absorbed.
Answer:
second one is the best which describes roots
The main function of root hairs is to absorb water and minerals from the soil.
What is the function of root hairs?The function of root hairs is to absorb water and nutrients from the soil and it sent to the upper parts of the plant. In roots, most water absorption happens through the root hairs.

1. Which layer is the oldest? Which layer is the youngest? How do you know?
2. What are some characteristics of the organisms in layers 1-6?
3. What are some characteristics of the organisms in layers 7-12?
4. Develop a theory as to how the organisms in this area changed over time.
Answer:
the youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials.the oldest is 12(upper one) because decomposed material are found at the top most of organisms.they are highly decomposed material.they don't decompose easilyThe youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.
What is Decomposition?Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.
The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.
Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.
Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.
