Answer:
The neutron is a subatomic particle, symbol n or n⁰ , with no electric charge and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Explanation:
A neutron is a subatomic particle denoted as n or n⁰, which has no electric charge and a mass slightly greater than that of a proton. It is found in the nucleus. So, the correct option is (C).
What is Neutron?Neutron is a type of subatomic particle which is found in the nucleus of every atom except hydrogen. This particle derives its name from the fact that it has no electric charge; It is neutral. Neutrons are very dense.
Neutrons have a neutral electrical charge i.e. neither negative nor positive and have slightly more mass than positively charged protons.
It can be found from the value of mass numbers and number of protons. Mass number is sum of neutrons and protons.
Thus, a neutron is a subatomic particle denoted as n or n⁰, which has no electric charge and a mass slightly greater than that of a proton. It is found in the nucleus. So, the correct option is (C).

2. If a cell has a very large amount of ribosomes attached to its rough
endoplasmic reticulum, what is the cell probably specialized to manufacture?
Answer:
Protein
Explanation
Ribosome and Rough E.R are organelles in the cell.
E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system called the reticulum.
Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.
They are small in number and are made up of RNA and protein.Generally the protein synthesised in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies

An amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. When an amoeba feeds, it first makes contact with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. the pH in the vesicle is then lowered and the contents are degraded.

What biomolecule determines whether an individual inherits the inability to produce the enzyme needed to break down the amino acids
Answer:
NUCLEIC ACIDS
Explanation:
Four biomolecules are found in living systems and they are responsible for every process undergone by cells of living organisms. Nucleic acid is one of the four biomolecules, which is the precursor of another biomolecule called PROTEIN.
DNA and RNA are the two nucleic acids which contains segments called GENES that encodes the information needed for the synthesis of proteins and transfer of this information to offsprings. Genes found on nucleic acid biomolecules undergo expression to produce proteins. ENZYMES are proteinous molecules that catalyse biochemical reactions in living systems.
From the explanation above, this means that ENZYMES that catalyze reactions like breaking down amino acids are PROTEINS, which in turn are made from GENES carried by NUCLEIC ACID biomolecules.
Therefore, NUCLEIC ACIDS determine whether an individual inherits the inability to produce the enzyme needed to break down the amino acids

A heterotroph eats food it finds itself, whereas an autotroph eats food found by other organisms. A heterotroph makes its own energy and an autotroph gets its energy from eating other organisms.
Answer:
An autotroph makes its own energy and a heterotroph gets its energy from eating other organisms.
Explanation:
Autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Heterotrophs cannot make their own food so they must eat or absorb.
I literally don’t know the answer to this Someone plz help
Answer:
Abiotic conditions would be the temperature of the reef, and also the amount of light that the living organisms receive. (aka coral and zooxanthealle algae)
Biotic would be coral, and also fish. A disturbance in the balance of an abiotic of biotic factor could in turn kill one of the many organisms needed to keep each other alive in symbiosis within the coral reef. In a domino effect, if one organism that is essential to the balance dies, then another, and so on until the coral reef itself dies.
despite being very different of diets that include different types of food containing different levels of biomolecules, these diets are all able to support human being in living. How is this possible?
Answer:
As nutrients, protein is overemphasized and carbohydrates are underrated in terms of their importance in our diets. Most people in the United States now eat more protein than their bodies need, and, somehow, carbohydrate-rich foods such as potatoes and bread have gotten a bad name for being fattening. Yet protein from animal sources often comes in foods that contain significant amounts of saturated fatty acids. And the only carbohydrate-rich foods that are truly fattening are those laden with fats and added sugar, such as pastries, cookies, and baked potatoes heaped with sour cream.
In fact, there is some evidence that diets high in carbohydrates may help reduce the risk of heart disease. Thus the Eat for Life guidelines suggest not to eat any more protein than you already do and to increase the amount of carbohydrates you eat to compensate for the lower amount of fat that your diet will contain.
This chapter presents the evidence that increasing the proportion of carbohydrates in the usual American eating pattern at the expense of fat will tend to lower chronic disease risk. It also discusses some of the health claims made for dietary fiber, a group of substances that are made up mostly of complex carbohydrates.

What is Plant cell?Plant cell is the basic unit of all plants. Plant cells are eukaryotic in nature. They have a membrane-bound nucleus and organelles. Plant cells have a cell wall surrounding the cell membrane.
The cell wall has many functions on which the life of the plant depends. Plant cell walls are composed of cellulose, which distinguishes them from other organisms with cell walls, such as bacteria (peptidoglycan) and fungi (chitin). Algal cell walls are similar to those of plants, and many contain specific polysaccharides that are useful for classification.
Examples of plant cells include different specialized cells like parenchyma, sclerenchyma and collenchyma cells.

A. Biogeography.
B. Anatomy.
C. Developmental biology.
D. Fossil record.
Answer:
D. Fossil record.
Explanation:
The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.
