Answer:
major role of carbohydrate in our is to supply energy for the body
Carbohydrates are sugar molecules, which are one of the primary nutrients required by the body.
The correct answer is:
Option C. Supply energy for the body
The role of carbohydrates are:
1. Carbohydrates are the primary source of energy in the body. The carbohydrates exist in the form of sugars, starch, and dietary fibers.
2. Carbohydrates are made up of monomers known as monosaccharides. Generally, glucose and fructose are the monomers of carbohydrates.
3. Beans, legumes, whole-grain products, and potatoes are good sources of carbohydrates in a healthy diet.

A. parasympathetic
B. somatic
C. peripheral
D. autonomic
Answer:
autonomic
Explanation:
edg 2020
Control of glands and the muscles of internal organs is a function of the autonomic nervous system.
What is autonomic nervous system?The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.
The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS).
Activation of the SNS leads to a state of overall elevated activity and attention: the “fight or flight” response. In this process, blood pressure and heart rate increase, glycogenolysis ensues, gastrointestinal peristalsis ceases, etc.
Therefore, Control of glands and the muscles of internal organs is a function of the autonomic nervous system.

Answer:
Zooxanthellae and coral have a mutualistic, symbiotic relationship. Coral obtains oxygen and organic products from the algae that live within them. These algae also help the coral remove waste. The zooxanthellae obtains needed carbon dioxide and needed nutrients from the coral. The coral also provides the zooxanthellae with a protected habitat. Because both organisms derive a benefit from their relationship, it is considered mutualistic.
A symbiotic interaction benefits both the species. Corals and zooxanthellae shows a symbiotic relationship where zooxanthellae produce oxygen and corals perform photosynthesis.
What is Symbiotic relationship?Symbiosis is a type of species interaction, it is any type of a close and long-term biological interaction which is between the two different biological organisms. Symbiotic relationships are mutualistic, commensalistic, or parasitic type. The organisms, are termed as symbiont.
The corals and the special cells of zooxanthellae have a mutualistic relationship. The corals provide the zooxanthellae with a protected surrounding environment and the compounds which they need for the process of photosynthesis. In return, the zooxanthellae produce oxygen for respiration and helps the coral species to remove waste materials.

A cell can be compared to a business. The Nucleus controls all cellular functions like a Chief Executive Officer that controls all of the operations and decisions of the business. Within the business there is the cytoplasm. The Cytoplasm in a cell, harbors cell organelles and provides structure. This compares to the factory work space that contains all the working bio-machinery and the nutrients, like the raw materials, for the cellular processes. The Cytoskeleton for a cell is what provides the shape and structure to the cell. This is compared to the architecture structure of a factory. It helps to support and strengthen the structure of the building. The Endoplasmic Reticulum of a cell is the site for protein synthesis, the vesicle packaging and transport. This is compared to an assembly line of the business. This is the main work space for production of the important cell components, for example the proteins. The Golgi Apparatus of the cell is the packaging of molecules into the transport vesicles. This is compared to the packaging department of a business. The packing department is the department that packages the goods that have been prepared. The Lysosomes of the cell is actually the membrane-bound cell organelle. It contains the digestive enzymes that break down the excess or the otherwise known worn-out parts of the cell. If the cell is considered damaged beyond repair it will help it to self-destruct with a process that is called programmed cell death. This is compared to the maintenance department of a business. The maintenance department is called in when there is old worn out machinery that needs replaced and discarded. The Mitochondria of the cell is in charge of producing the energy through cellular respiration. This is compared to the power plant or the generator of the business to help the production of energy. There are a few extra parts of the cell that could not be put on the chart above. The Plasma membrane of the cell is the semi permeable that controls cellular transport. This is compared to the Logistics department of the business. This department is in control of what is shipped in and out of the business. The last one is the Ribosomes of the cell. This Ribosomes are like the protein builders or the protein synthesizers of the cell. This is compared to the factory workers of the business. The works build the products for the company.

A sample of food is dehydrated, which kills all of the bacteria. However, in a few days, bacteria-free water is added to the food in a bacteria-free environment. Nevertheless, microscopic investigations indicate that bacteria are in the food. How did the bacteria get there?
Explanation:
well some bacteria are protected by a special coat outside their body which prevents any water loss from the bacteria. Such bacteria can then reproduce after conditions return to normal.
When a sample of food is dehydrated and making it bacteria-free, but in a few days bacteria are found in the food, it shows, bacteria which are there were in the food as endospores.
What are endospores?Endospores are the alternate stage of bacteria, which is the dormant stage, genus Bacillus, and the genus Clostridium, are examples of bacteria that make endospores.
These endospores are resistant to physical and chemical treatments, so this makes it easier for bacteria to survive in stressful conditions. It is a major threat to the food industry which provide heat treatment to the bacteria but they show resistance due to spore formation.
Therefore, when a sample of food is dehydrated to kill all of the bacteria in the food, but microscopic investigations indicate that bacteria are in the food, it is due to endospores.

Grassland ecosystems in Texas have evolved to depend on periodic fires to return nutrients to the soil and encourage plant reproduction. Humans have prevented fires in many of these grassland areas, resulting in plant and animal communities with very little diversity. Wildlife biologists often recommend purposefully starting fires called prescribed burns, which are monitored and controlled, in grassland ecosystems every 3 to 4 years. These biologists observe greater diversity in plant and animal life in the years following a prescribed burn.

Study these diagrams. The dots represent valence electrons orbiting the nucleus of an atom. Which diagram shows the valence electron pattern for a carbon atom? Four options A, B, C, and D showing different atomic structures with a nucleus at the center and valence electrons in circular path
Answer:
The image having four outermost (valence) electrons and a nucleus at the center
Explanation:
Even though the images were not displayed in the question, but we know that carbon is a member of group 14 in the periodic table.
Every member of this group possess four electrons on their outermost or valence shell in addition to the nucleus at the center of the atom.
Hence the structure having four outermost electrons and a nucleus represents carbon atom.

The monosaccharide serves as the building block of glycogen, a polymer made up of many glucose molecules. So, the correct option is (B).
What is Polymer?A polymer is defined as a substance or material consisting of very large molecules known as macromolecules, which are made up of many repeating subunits. Due to their wide spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
During the process of polymerization, polymers are formed in which smaller units known as monomers are joined together with the help of covalent bonds. Polymers are of four types:
1. Natural
2. Synthetic
3. Addition
4. Condensation
In above given example, Monosaccharide which is glucose is the monomer which is joined together to from glycogen which is a polymer.
