Read the information for transcription and then answer the question.
Protein Synthesis
Explain the process of transcription
Answer:
Protein synthesis is the process which synthesizes proteins by the information coded in the DNA molecule with the help of two distinct process takes place in order namely transcription and translation.
Transcription is the first process of the central dogma or the protein synthesis that produces mRNA molecule that carries all the information stored in the DNA molecule out of the nucleus (in eukaryotes only) to the ribosome where the second process Translation takes place.
Untwists then unzips of DNA molecule is catalyzed by RNA polymerase result in the Hydrogen-bonds between the strands break .
Creates complementary base pairs with bases of the DNA strand with help of free RNA nucleotides
weak hydrogen bonds and sugar-phosphate bonds form between base pairs and RNA nucleotides respectively
mRNA strand is synthesized and peels off the DNA and transported or pass from the nucleus to cytoplasm

2. Which blood type would you have if antibodies A and B were made during your first year of life?
Answer: the possible possibilities are 3 if u have an A and B type of antibodies.
Explanation:
it can be -- AO or AB or BO
plus factor will depend upon enzyme presence.
If a person is having both anti-A and anti-B antibodies in blood then the possible blood group of that individual can be O. However, Rh factor cannot be determined by this information.
What is Blood Group?Blood grouping is the system of classification of blood on the basis of antibodies and antigens in blood which are inherited substances present on the surface of the red blood cells.
Blood groups are classified into four types. These are A, B, AB and O. Blood group A has antigens A on the RBCs with anti-B antibodies present in the plasma. Blood group B has B antigens on RBCs with anti-A antibodies in the plasma. Blood group O has no antigens on the membrane of RBCs and antibodies of both types anti-A and anti-B antibodies in the plasma. Blood group AB has both A and B antigens, but no antibodies in the plasma.

PLEASE HELP ME WITH THIS AND HURRY WILL MARK AS BRANLIEST!!!!!! Why do leaves change color in the fall? Research this phenomenon and write a two-page report describing what happens. 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.
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

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

C. The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density.
D. The formation of sea ice removes freshwater, leaving dissolved solids behind and increasing the density of seawater.
The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density. The correct option is C.
What is salinity?The concentration levels of salts in water or soils are referred to as "salinity."
Salinity is classified into three types based on its cause: primary salinity (also known as innate salinity), secondary salinity (also known as dryland salinity), and supplementary salinity (also called irrigation salinity).
When the water table rises, natural salts rise to the surface; in sufficient quantities, these salts become toxic to most plants.
As a result, the surrounding seawater becomes saltier because salt is left behind when sea ice forms.
As seawater becomes saltier, its density rises and it begins to sink. Surface water is drawn in to replace sinking water, which eventually cools and salts enough to sink.
Thus, the correct option is C.

in unicellular organisms, what makes up the organism
Answer:
Unicellular organisms include bacteria, protists, and yeast.
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
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.

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
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

Explanation:
All of those cells are types of specialized cells. They are cell specifically designed for a specific job.
if a sample contains 20g of an isotope that has a half life of 1000 years how much will be left after 2000 years
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.
