1. How can studying compounds in plants and animals benefit people? Give an example of how a compound found in a plant has been used to benefit humans.
2. What is meant when describing water as a polar compound?
Please answer what the question is asking exactly many points will be given.
Answer:
It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.
Explanation:
Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution
Describe and discuss the amino acids. Include information on what they are, their structure, and how many there are. Using your best grammar, write 3-5 sentences.
Answer:
molecules that combine to form proteins
Explanation:
amino acids are molecules that combine to form proteins. amino acids and proteins are the building blocks of life. when proteins are digested or broken down amino acids are left
Amino acids are building blocks of proteins. They contain an amino group, carboxyl group, and side chain. There are 20 types, each with unique properties influencing protein structure and function.
Biochemical functions depend on amino acids in proteins. The R-group, amino group, and carboxyl group are on each amino acid. This side chain gives each amino acid chemical properties that impact protein structure and function. Twenty typical amino acids make up proteins.
They vary in size, shape, charge, and hydrophobicity. Peptide bonds generate polypeptide chains that fold into three-dimensional forms, determining a protein's function. The structures include simple helices and complex globular shapes. Complex and diverse, proteins perform various tasks in living things due to the diversity of amino acids and their interactions.

When one organism benefits but the other is harmed, their relationship is called . Occasionally, two organisms have a relationship where one organism benefits and the other is neither hurt nor helped. This type of relationship is called .
Answer:
A close, interdependent relationship between two organisms is called SYMBIOSIS . There are three main types of symbiotic relationships. In MUTUALISM, both organisms benefit from the relationship. When one organism benefits but the other is harmed, their relationship is called PARASITISM. Occasionally, two organisms have a relationship where one organism benefits and the other is neither hurt nor helped. This type of relationship is called COMMENSALISM.
The type of relationship where one organism benefits and the other is neither hurt nor helped is called commensalism.
What is commensalism?In biology, commensalism is a connection between members of two different species in which one species uses the other for food or other purposes without causing the other any damage or gaining anything in return.
The commensal, or species that gains from the connection may take resources from the host species, which is unharmed, or find refuge, support, or means of movement. Frequently, a bigger host and a smaller commensal are in a commensal relationship.
The commensal species may exhibit significant morphological adaptation, whilst the host organism is virtually unaffected by the contact. Contrasting this connection with mutualism, which benefits both species,
A well-known illustration of a commensal is the remora (family Echineidae), a fish that travels in close proximity to sharks and other fish. Remoras have developed a flat, oval-sucking disc structure on top of their heads that cling to the bodies of their victims.
Remoras and pilot fishes both eat the leftover food from their hosts. Bird species like the magnificent egret (Ardea alba), which feeds on insects discovered by grazing animals or on soil creatures stirred up by plows, are other instances of commensals.
Therefore, this type of relationship is called commensalism.

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

In chloroplasts, when the two photosystems work in series, electrons ejected from the photosystems do not return to them, which is known as ______. Multiple choice question. oxygenic photophosphorylation cyclic photophosphorylation noncyclic photophosphorylation NADPH based photophosphorylation
When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.
Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.
Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems one and three, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.

Explanation:
if rRNA is produced in nucleolus then how it performs and give protein as a rhibosome??
Nucleolus is site for production of ribosomal RNA not ribosomes. While ribosomes constitute both rRNA and protein they are assembled after transcription. rRNAs associate with the ribosomal proteins, forming the two types of ribosomal subunits (large and small). These will later assemble in the cytosol to make a functioning ribosome. In prokaryotes ribosomal RNAs are coded in operon systems (nearly 20) and absence of a nucleolus in way hampers their production.
