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.

Explanation:

The human body has the ability to thermoregulate, so when the temperature rises, the blood vessels dilate, and the body emits more heat than it receives, and therefore sweat is released to cool the body. Hence, the higher the temperature the greater the sweating

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.

Protein

Explanation:

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.

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.

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

Answer:

1. Protein - build lean muscle and strengthen tendons

2. Lipids - insulation and long-term energy

3. Carbohydrates - provides quick, easily digested energy

4. Nucleic Acids - repair and replicate DNA and RNA

Explanation:

a. Think of protein as what helps your muscles grow and strengthen

b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)

c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.

d. nucleic acids -  think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.

Before it was known as "science," this branch of study was called Natural Philosophy.

The pursuit of knowledge is what is meant by the term "science." This approach describes and provides an explanation for natural occurrences based on observations and experiments. The term "science" can also refer to the arranged body of information that has been accumulated by individuals via the application of that system.

A person who works in a particular field of science and possesses in-depth knowledge about that field is called a scientist. Or, to be more general, anyone who studies or works in a scientific field is considered to be a scientist.

Answer:

B is the answer

Explanation:

continual daylight

In the given image it is showing long days. The correct option is A.

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.

Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels.

Explanation:

Based on "Sickle cell anemia is an inherited red blood cell disorder" taken from the text, I would say the correct answer is C, because it says "an inherited disorder" and describes Sickle cell anemia.
