Answer:
The question is incomplete because the options are not given but the options are gotten from another websites which are;
a. protein
b. complex carbohydrate
c. fats
d. disaccharides
The correct option is a.
Protein.
Explanation:
Proteins are macro nutrients or biomolecule whose building blocks is t amino acids. Amino acids consists of organic compounds like hydrogen, nitrogen, carbon, oxygen and may also contain sulfur which all serve as protein building blocks . Our body requires proteins which contain amino acids and these are important for growth, body building and and proper functioning. These include both essential and non essential amino acids
The essential amino acids includes histidine, isoleucine, lysine, phenylalanine, tryptophan and valine cannot be produce by the body but can be gotten from diets that are from protein source. The major sources of essential amino acids are gotten from animal proteins and they include meat, eggs, and poultry.
The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait.
A Punnett square is shown. The columns are labeled Upper F and f. The rows are labeled Upper F and f. Clockwise from upper left the boxes contain: Upper F Upper F, Upper F f, Upper F f, f f.
Based on the Punnett square, what is the probability that the offspring will have freckles?
25 percent
50 percent
75 percent
100 percent
Answer:
75%
Explanation:
Three of the boxes contain an Upper case F, therefore 75% of the boxes have an Upper case F. It's like quarters, if you have 4 quarters you have 100 cents, if you have 3 you have 75 cents, if you have 2 you have 50 cents, and if you have 1 you have 25 cents.

What is binary fission?
A form of sexual reproduction used by some unicellular organisms to produce two cells that are genetically different from each other and from the parent cell.
A form of asexual reproduction used by some multicellular organisms to produce two cells that are genetically identical to each other and to the parent cell.

A form of sexual reproduction used by some unicellular organisms to produce two cells that are genetically identical to each other and to the parent cell.
Answer:
The 3rd answer
Explanation:
Binary Fission is the process of cell division in prokaryotes (bacteria). It is a type of asexual reproduction. If the parent cell has 18 chromosomes than each daughter cell will also has 18 chromosomes.
. If energy is the ability to cause change, then what evidence is there that energy is produced in the interaction between the wind and the blades of the wind turbine?
Answer:
Explanation:
Wind is considered to be kinetic energy. As the kinetic energy of the wind hits the fans of the wind turbine it causes the fans to spin. This then causes the blades to spin a rotor which is connected to the main shaft of the turbine itself. This rotor spins and generates electricity. Therefore, the kinetic energy that was initially introduced into the system goes through a process and gets converted into electrical energy which we can use.
Which factor may increase a rabbit population?(1 point)
decrease in space
decrease in temperature
decrease in food
decrease in predators
Answer:
D. Decrease in predators
Explanation:
The lack of predators would cause less death to the rabbit population, with less hunters to kill the rabbits the population will increase and further increase if they reproduce.
The factor that will increase a rabbit population is ( D ) Decrease in predators
Rabbits as primary consumersRabbits are herbivores that feed on nuts and grasses they are primary consumers and are prey to so many secondary and tertiary consumers ( i.e predators ).
A decrease in space will result to lose of habitat and this will decrease the population of rabbits also extreme weather conditions might lead to death of rabbits just like decrease in food will cause starvation and eventual death for rabbits as well.
While a decrease in predators will result in the survival of more rabbits ( i.e increase in population )
Hence we can conclude that The factor that will increase a rabbit population is Decrease in predators.

Why must cells divide to stay small or change shape to reduce volume?
O To diffuse substances from an area of higher to lower concentration
To ensure the cell is able to obtain nutrients or remove wastes.
To reduce surface area of the cell for quick movement.
O To move water molecules from areas of high to low pressure
Answer:
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Explanation:
Answer:
To ensure the cell is able to obtain nutrients or remove wastes.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume That is why cells are so small.

How would you describe dominant in a different way then this? In a easy way?
Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. The allele is dominant because one copy of the allele produces enough enzyme to supply a cell with plenty of a given product.

Which is a density-dependent factor?
Answer:
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

There are economic concerns surrounding the products that have been genetically engineered for particular traits, including pharmaceuticals, crops, and enzymes that are used in industry and manufacturing processes. Which is LEAST likely to be an economic concern that affects society? O patented products birth defects land use O cost of genetically engineered seeds
Answer:
Birth defects
Explanation:
Edge
Birth defect is least likely to be an economic concern that affects society.
What is society?Society is defined as a neighborhood, country, or large group of people who share customs, institutions, and activities and interests. The building blocks of society are people's relationships with one another and the structures they create. As a result, society is not a collection of people but rather the intricate web of social rules that develop among them.
Birth problems such as spina bifida, cleft lip or palate, gastroschisis, hypospadias, chromosomal congenital anomalies including Down syndrome, and various heart and blood vessel defects have been linked to living close to hazardous waste sites.
Thus, birth defect is least likely to be an economic concern that affects society.

A. transcription
B. translation
The nucleus is the site of transcription in protein synthesis.
What do you mean by Transcription?Transcription may be defined as a process through which a cell makes a copy of RNA (mRNA) from a strand of the DNA.
These messenger RNA carries the genetic information which is essential to make a protein in a cell. The process of transcription occurs in the nucleus of the cell.
While translation is the process by which the sequences of mRNA may transform into proteins. This process occurs in the cytoplasm of the cell.
Therefore, the nucleus is the site of transcription in protein synthesis.
