Answer:
it happens with they mind bro
Answer:
Angiosperms or flowering plants maintain homeostasis by keeping their stomata (opening in the underside of a leaf that allows carbon dioxide to diffuse into and out of the leaf) open just enough to allow photosynthesis to take place but not so much that they lose an excessive amount of water.

● History of Ribosomes./ pls describe and write so facts
Answer:
Ribosomes are small dense and granular ribonucleoprotein (i.e., RNA and protein) particles found attached on the outer surfaces of endoplasmic reticulum and nucleus as well as freely scattered in cytoplasm, mitochondrial matrix and chloroplast.
Explanation:
History of Ribosomes:
Ribosomes were first isolated from E. coli by Tissieres and J. D. Watson (1958), who found that ribosomal RNA alone accounts for 22% of the total weight in rapidly growing cells (90% of total RNA). Palade (1953) was the first to observe the ribosomes as dense particles or granules in electron microscope. Upon isolation they were shown to contain approximately equal amounts of RNA and protein.
Size of Ribosomes:
There are mainly two sizes of ribosomes — (i) One is smaller prokaryotic found in bacteria and blue—green algae, having a sedimentation coefficient 70S equivalent to a molecular weight of 2.7 × 106 daltons. (Dalton is the unit of molecular weight. One Dalton is equal to the weight of one hydrogen atom), (ii) Other is of eukaryotic cells of plants and animals of 80S coefficient with a molecular weight of about 4 × 106 daltons.

Answer:
DNA is transmitted to mRNA, which then attaches to a ribosome where it is translated into a protein.
I looked up the definition of transmitted and it fits better
DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The correct answer is option C.
What is the role of mRNA ?mRNA is the code of DNA that carries the information of coding proteins from the nucleus to the cytoplasm.
DNA is transcribed into mRNA where it is transcribed intro message to which kind of protein is about to be formed. A triplet forms one amino acid and this process is taking place in the ribosome.
The chain of amino acids forming a protein is released in the cytoplasm and the proteins is then assigned a particular position where so ever is them needed mostly in the cytoplasm.
Therefore, DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The activity takes place in the ribosome.

how does one chromatid compare to its sister chromatid?
Answer:
One chromatid compares to its sister chromatid because when a chromatid is replicated, a sister chromatid is formed. The sister chromatid will be a genetically identical copy to the chromatid because the cell being replicated will also be genetically identical.

where are the motor proteins that move chromosomes toward the poles of the mitotic spindle located?
Answer:
They are at or near the ends of the microtubules. I hope this helps you! :D
Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.
What are motor protein?Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.
Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.
Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

Explanation:
Answer:When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is essential to life.

After first exposure to an antigen, about how long does it take for antibodies to reach a detectable level?
2. What could explain the significant increase in antibodies to non-Lyme disease antigens (blue line)?
3. Lyme disease patients who are treated with antibiotics quickly usually do much better than those who are treated later. Why do you think this is the case?
4. Why doesn’t the Antibodies in Lyme Disease Antigens (orange line) decrease after the first immune response, compared to non-Lyme Disease Antigens (blue line)?
5. Professor Dr. Utpal Pal studied the Borrelia burgdorferi bacterium at the University of Maryland. Dr. Pal found that Lyme disease is caused by your immune system. When the body is infected with Lyme disease, it overreacts causing inflammation in the joints. Although antibiotic resistance has not been observed for B. burgdorferi, create an argument defending the control of antibiotic use to the public. Analyze the data in the graph below by answering the following questions. Be sure to use complete sentences.
After first exposure to an antigen, it can take about three weeks for antibodies to reach a detectable level. The body will react to disease by creating antibodies and testing their effectiveness against the unknown antigen.
Antibodies are the body's way of fighting off foreign threats. Also known as immunoglobulin, they detect and attack pathogenic bacteria and viruses. These antibodies detect a protein that is unique to the surface of the pathogen called the antigen.
At times, we can see an increase in antibodies for one disease, for example, Lyme disease, in the presence of non-Lyme disease antigens. This is often due to antigenic variation, which is a method used by pathogens to mask their respective antigens. There are also general use antibodies that will increase in reaction to any pathogen.
As with any illness, a patient who receives treatment sooner will fare better than those whose treatment is delayed. This is due to the fact that earlier treatment with antibiotics will allow the body to fight off the infection before the bacteria can reproduce further.
After the first immune response, antigen-specific antibodies will remain for some time to provide the body with "immunity" to the pathogen, while general-purpose antibodies will return to a base value.

Why should we not sleep under peepal tree at night?
This question is partially wrong guys .There is no such danger around peepal tree see the researchs and decide yourself.
some people have written wrong information in this group kindly request you guys to correct wrong information and get new information.
Plants take in carbon dioxide (CO2) and release oxygen (O2) during day time when they undergo the process of photosynthesis and they take in O2 and release CO2 during night as a result of respiration.
There are 3 photosynthesis pathways adapted by plants for carbon fixation namely C3 pathway (Calvin cycle), C4 pathway and CAM pathway (Crassulacean Acid Metabolism). C3 and C4 are common among land plants and among these two, C3 is the most common.
CAM pathway can be seen in desert plants and epiphytes (i.e. plants that live on other plants). Unlike C3 and C4 plants, these plants keep their stomata closed during day and open it during night for fix CO2 in the form of malate and releases O2. They do it so, to prevent loss of water due to sunlight. During the day, they breakdown the malate and use the released CO2 through Kalvin cycle to produce sugars, similar to C3 plants. So, CAM plants releases oxygen during night.
Peepal tree is a hemi-epiphyte in its native habitat i.e. the seeds germinate and grow as an epiphyte on other trees and then when the host-tree dies, they establish themselves in the soil. When they live as an epiphyte, they use CAM pathway to produce carbohydrates and when they live on soil, they switch to C3 type photosynthesis. So, a Peepal tree can also release oxygen during the night depending on whether it is an epiphyte or not.
Other plants that give out oxygen at night are Areca Palm, Neem tree, Snake plant, Aloe Vera, Gerbera and Tulsi.
