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.

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.

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

_____ is the process by which energy is stored in inorganic molecules is used to produce carbohydrate food molecules
Answer:
Chemosynthesis
Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.
that is the answer
Photosynthesis is the process by which energy stored in inorganic molecules is used to produce carbohydrate food molecules.
What is photosynthesis?Photosynthesis is the primary process by which plants, algae, and some bacteria capture and store energy from the sun.
During photosynthesis, light energy is absorbed by pigment molecules in the chloroplasts of plant cells. This energy is then used to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The glucose produced during photosynthesis is used by the plant as a source of energy and is also stored as a carbohydrate reserve. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.

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.

Which of the following BEST describes the length of days in Australia when the Earth and sun are positioned as shown in January in the diagram above?
long days.
continual daylight.
short days.
continual darkness.
Answer:
B is the answer
Explanation:
continual daylight
In the given image it is showing long days. The correct option is A.
What is the relation between day and night?The Earth orbits the sun once every 365 days and rotates once every 24 hours on its axis.
Day and night are caused by the Earth rotating on its axis rather than by its orbit around the sun.
The term "one day" refers to the time it takes the Earth to rotate once on its axis and includes both day and night time.
A day is roughly the time it takes for the Earth to rotate or for other large astronomical objects to rotate.
The number of daylight hours we have depends on our latitude and how the Earth orbits the sun.
The axis of rotation of the Earth is tilted relative to its orbital plane and always points in the same direction means toward the North Star.
Thus, the correct option is A.

The term that describes when an enzyme loses shape and function.
Answer:
Denature
Explanation:
Denature
Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.
Active sites and substrate specificity
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.
In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!
The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens

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.
