Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

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.

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.
Answer:
Ghost can come if anyone sleeps under peepal tree
Why isnt there a solar eclipse during every new moon?
Answer:
Eclipses do not happen at every new moon, of course. This is because the moon's orbit is tilted just over 5 degrees relative to Earth's orbit around the sun. For this reason, the moon's shadow usually passes either above or below Earth, so a solar eclipse doesn't occur.
Explanation:
Make this in own words if it's for a test or smth
Explanation:
Solar eclipse don't happen every new moon, because the moon's orbit tilted over degrees relative to the earth's orbit around the sun. The moon's shadow usually passes either above or below earth, so therefore that is the reason a solar eclipse does not occur every new moon

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.

During one year, the birthrate in a country is 28 births per 1000 people, and the death rate is six deaths per 1000 people. What is the population growth rate?
Answer: 22
Explanation: 28/1000-6/1000=22/1000
Birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.
What is Birth Rate?Birth rate is the total number of people born per year per 1000 in the population. Birth rate is also known as Natality.
For example, if 65 births occur per year per 1000 individuals, the birth rate is 65. If it is expressed in the percentage, it is 6.5 per 100 or 65%.
Population is divided into many parts like Juveniles (Period before puberty), adults and Post reproductive adults. Birth rate is higher than the death rate as the population is younger, the faster that population grows.
When the birth rate is expressed as per the age group, this is called the standardized birth rate. Birth Rate is determined by the ratio between the number of live births in a population during a year and total mid-year population for the same year multiplied by 1000.
Thus, birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.
