4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction

Answers

Answer 1

Answer: A. the gravitational pull of the Sun

The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.

I don’t understand biology at all and I am worried about how to pass biology . Does anyone have study tips for biology or anyways that can help me relearn everything

Answers

Answer:

Biology is not a hard class however it does require memorization and comprehension of certain topics. I recommend that you read over the chapters and make flashcards and test yourself. You can also ask your teacher for help. There are many videos available that do a great job at explaining each topic in biology. In addition, there are various websites that can also provide information. You should make study groups with your classmates as it is a more fun and effective way of studying.

Answer:

Firstly, don't stress, you'll get through it. Worrying will just slow you down, and learn Biology as something you get to do, and not a chore.

And if you want to relearn everything from the beginning, then I would recommend  Crash Course's free Biology courses on YT, they also have Chemistry courses and everything. You can also go to Ask a Biologist,   where you can do more than just ask questions.

There are so many more sources of information and everything, but one thing is; don't stress, that's the key.

Good luck, stay safe and healthy.

You'll get through it! Don't worry. If you want me to recommend more websites to you, just comment on this answer :D

if a sample contains 20g of an isotope that has a half life of 1000 years how much will be left after 2000 years

Answers

5 grams will be left. After the first 1000 years, there will be half of 20 left, or 10. After 2000 years, half of 10 will remain, which is 5.

After 2000 years, there will be 5g of the isotope remaining.

What is an isotope?

If an isotope has a half-life of 1000 years, it means that after 1000 years, half of the original sample will have decayed. After another 1000 years (2000 years total), half of the remaining sample will have decayed, and so on.

To calculate how much of the sample will be left after 2000 years, we can use the following formula:

[tex]N = N_{0} * (1/2)^ (t/T)[/tex]

where:

N = the amount of the isotope remaining after time t

N0 = the initial amount of the isotope

t = the time that has elapsed

T = the half-life of the isotope

Plugging in the values from the problem, we get:

N = 20g * (1/2)^(2000/1000)

N = 20g * (1/2)^2

N = 20g * 1/4

N = 5g

Therefore, after 2000 years, there will be 5g of the isotope remaining.

A woman of childbearing years who is not pregnant has _______ absorption rate of calcium as compared to a woman who is pregnant

Answers

Answer:

The correct answer is - lower

Explanation:

Pregnant women require an increased amount of calcium as it can provide a sufficient amount of calcium for herself and her fetuses. During lactation, the calcium is reabsorbed very fast and rapidly that supplies the calcium for the milk. So, the normal women of childbearing age do not require the amount of calcium as pregnant women require.

Thus, there is a lower absorption rate of calcium as compared to a pregnant women

Be sure to include an introduction and a conclusion to your report. Use the information you have learned in this lesson about chlorophyll, the green plant pigment, and its role in photosynthesis to help you explain what happens in the fall.​

Answers

Answer:

Leaves are always the color they turn in the fall

Explanation:

The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.

I hope this helps and good luck on that two-pager!

Answer:

During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible

Explanation:

The plasma membrane is selectively permeable. It allows some substances to enter and leave the cell unrestricted while others are restricted. Some toxins produced by certain bacteria cross the plasma membrane, interfering with normal chemical reactions, and ultimately killing the affected cell. Why are cells unable to stop the flood of these harmful substances into the cell

Answers

Answer:

There are specific receptors present on the surface of the normal cell membrane to recognize the molecules to allow them to pass or not. Most of the bacterial toxin are water-soluble molecules, and bound to the cell surface and interact with them as some time antibody-antigen interaction or cell recognition does not occur that form a pore in the cell membrane and toxins move into the cell.

Once toxins enter the cell they attack intracellular targets through endocytic vesicles. Ultimately these ends in cell death.

The cells are not able to stop the flow of the mentioned harmful substances into the cell as they fail to recognize them as foreign entities. These foreign toxins have intracellular targets with which they bind and lead to death of the cell.

Cell death due to foreign toxins:

The plasma membrane is formed of lipids. The toxins produced by the bacterial cells are water soluble. Therefore, they identify particular receptors on the membrane and associate with them. Thus, cell at certain occasions fail to identify them as foreign entities.

They combine with the plasma membrane of the cell and induce pore formation, however, there are many toxins that invade the cell and possess intracellular targets via endocytic vesicles. With the help of these vesicles, they deliver their enzymatic domain into the cytosol and results in the death of the cell by obstructing the metabolism of the cell.

Thus, cells fail to identify the bacterial toxins as foreign entities and they invade the cell and results in cell death.

If a woman is heterozygous for widow's peak
(widow's peak is dominant over a smooth hairline) has children with a man with a smooth hairline, what
are the possible phenotypes of their children?
It is impossible to determine the possible phenotypes.
O All of their children will have a widow's peak.
O None of their children will have a widow's peak.
It is possible for their children to either have widow's peak or a smooth hairline.

Answers

Answer:

It is possible for their children to either have widow's peak or a smooth hairline.

Explanation:

Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).

A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.

The cross is Ww x ww

                    W               w

    w            Ww            ww

    w           Ww           ww

There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.

So, It is possible for their children to either have widow's peak or a smooth hairline.

What is the alien invasion in the Florida Everglades?​

Answers

The foreign Burmese Python has disrupted the entire animal population in the Everglades. These invaders from Asia have proved to be extremely detrimental to Florida’s ecological systems, based on factors including their size, rapid reproduction, predatory diets, and Florida’s weather and climate conditions. Due to these multiple elements, Burmese Pythons have taken over the Everglades and have shown no signs of stopping. The problem becomes even more difficult to handle when the environmental controls taken to remove these pythons fail to counter the increasing python population in the Everglades. In other words, because of the biology of these snakes, the problems they bring to the South Florida food chain and the lack of removal of the invasive predators, Burmese Pythons create major issues for the ecosystem and are likely to spread if not controlled quickly. Hope that is enough! :)
