I WILL DUB THEE BRAINLIEST!! 50 points! Which of the following statements BEST describes the importance of carbon in the cell? Select one: a. Carbon is waste inside the cell and must be removed from cells. b. Carbon is used by the cell to balance salt concentrations inside the cell. c. Carbon provides structure and affects the function of a cell. d. Carbon maintains the proper temperature inside a cell. Love you guys! Hope you are all staying safe and well
Answer:
C.
Explanation:
I would say that answer choice C is the best out of this selection. Carbon is the main element in organic compounds, and organic compounds just so happen to make up the cells that carry out life processes for all living things. Hope this helps.
When Carbon is combined with other molecules like oxygen, hydrogen, Carbon forms essential compounds for the maintenance of life, including sugars, alcohols, fats, aromatic esters, carotenoids etc. In fact the carbon composes the cell itself since it forms the basic structures of the cell membrane: Cholesterol, Phospholipids, Carbohydrates.
Hope this helps! :)

What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 100x and an ocular lens power of 10x
Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.

The diet of a body builder should contain a large amount of proteins.
Why is protein important for body builder?Proteins are essential nutrients for a person's body. They are a component of constructing biological tissue and can be utilized as fuel. The energy density of proteins is 4 kcal (17 kJ) per gram, the same as that of carbohydrates. In contrast, the energy density of lipids is 9 kcal (37 kJ) per gram. The most important aspect and defining characteristic from a nutritional standpoint is the arrangement of amino acids in protein.
Because it contains amino acids, which are the actual building blocks of muscle tissue, protein plays a specific role in bodybuilding. Studies demonstrate that dietary protein and an amino acid-rich diet encourage protein synthesis, the formation of lean muscle, and muscle repair.

amino acid is deaminated.this is the removal of:
Explanation:
Deamination is the removal of an amino group from a molecule.Enzymes that catalyse this reaction are called deaminases.
In the human body, deamination takes place primarily in the liver, however it can also occur in the kidney. In situations of excess protein intake, deamination is used to break down amino acids for energy. The amino group is removed from the amino acid and converted to ammonia. The rest of the amino acid is made up of mostly carbon and hydrogen, and is recycled or oxidized for energy

Why does a flap in your throat close when you swallow
AnswerDuring breathing, air travels from your mouth and pharynx into the larynx (toward your lungs). When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement.:

Identify and explain how the central nervous system is supported and protected.
Answer:
The brain and the spinal cord are wrapped in three protective layers of tissue called the meninges. The cerebral spinal fluid goes between these layers to provide more cushion and protection. It nourishes and protects the nerve tissues of the brain and spinal cord. It also acts as a shock absorber, considering humans move a lot and fall.
The central nervous system is supported and protected by two coverings such as bone and membranous coverings.
What is the central nervous system (CNS) is made up of?The central nervous system consists up two major parts such as brain and spinal cord. This system is involved in integrating and coordinating the activities of the whole body.
The major role of the CNS is to control our thoughts, movements, emotions and desires. Beside this, it controls our breathing, heart rate, the release of hormones, body temperature etc.
The fluid present in CNS called as a cerebrospinal fluid which protects our brain from external injury.
As the brain is located within the cranial cavity of the skull and the spinal cord lies in the within the vertebral column, or spine.
The bony coverings, the brain and spinal cord are invested by three concentric membranous envelopes called as Meninges, which protect CNS over ally.

DNA is a molecule found in all cells.
Which problem does this model of DNA solve?
A. Real-life DNA is too dangerous for students to handle.
B. Real-life DNA is too large to fit in a test tube.
C. Real-life DNA is too rare for students to handle.
D. Real-life DNA is too small to see with unaided eyes.
What’s the answer
The problem that this model of DNA solve is as follows:
Real-life DNA is too small to see with unaided eyes.Thus, the correct option for this question is D.
What do you mean by Model of DNA?A model of DNA may be defined as a process through which the DNA is systematically produced/developed with the help of a double helical structure with each strand held together by hydrogen bonding between the bases.
The length of human DNA is found to be 1.8 meters long. But the real-life size of DNA is actually too small that it can be visualized with unaided eyes. There are about 3 billion nucleotide sequences are present in human DNA. It is considered the genetic material of almost all living organisms.
Within the structure of DNA, several nucleotide sequences like adenine, thymine, guanine, and cytosine are held with the help of hydrogen bonding.
Therefore, the correct option for this question is D.

Answer:
The correct answer is - the cytoskeleton.
Explanation:
A cytoskeleton in a cell is that appears as a dense network of whiplike fibers, tubules, and filament which maintain the shape and strength of the cell by interconnecting various cellular structure with one another.
