Have you ever wondered how we can grow from one cell to millions? How do you think this happens?
Answer:
If you think about it, the fact that a single cell can grow into an adult with trillions of cells is pretty awesome. ... It's a process called the cell cycle. Entire organisms grow, and develop by going through the cell cycle again and again. The cell cycle also helps us maintain a healthy body.
From a single cell to multiple cellular organism is formed by different complex mechanism like by cell division which involves a central dogma of life includes three process such as replication, transcription and translation and fourth one is reverse transcription.
what is central dogma ?The ‘Central Dogma’ is the flow of transfer of genetic information, from DNA to RNA to make a functional product, a protein, was first proposed in 1958 by Francis Crick.
DNA contains the genetic information needed to make proteins, and RNA act as a messenger that carries this information to the ribosomes where the information is translated into protein.
The process by which the DNA information converted into protein called gene expression which can occur in two stages like transcription and translation.
The central dogma occurs most frequently in our cells in three stages such as DNA replication that refers to make new DNA from pre existing DNA, transcription to make RNA from DNA and translation from RNA to protein.
Reverse transcription is defined as the transfer of information from RNA to make new DNA in a reverse manner which occur mainly in retroviruses, such as HIV.

What is meant by a phenotype ratio in a Punnett square? (1 point)
A. the fraction of possible offspring that can be observed to have a trait
B. the number of genes that are possible in offspring
C. the number of alleles in possible offspring
D. the fraction of possible offspring that contain a certain allele in their genes
Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.
A punnet square is a diagram used to attempt to predict the genetic composition for the offspring of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.
This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the offspring pertaining to this cross.

2. name the products in the equation
3. state whether this reaction is endothermic and explain how you are able to recognize this
4. state whether this reaction is anabolic or catabolic and explain how you are able to recognize this
According to the image,
1. The reactants of photosynthesis is carbon dioxide, water, and solar energy.
2. The products of photosynthesis is glucose and oxygen
3. The photosynthesis reaction is endothermic. For a reaction to be endothermic, energy (in this case, solar energy) must be put into the system in order for the reaction to occur. Whereas, exothermic reactions are spontaneous and don't require an initial input of energy.
4. Photosynthesis is an anabolic pathway. Carbon dioxide and water are utilized to synthesize glucose. Whereas, the process of glycolysis is catabolic because you break down glucose into 2 molecules of pyruvate.

An organism’s scientific name consists of which TWO taxonomic groups? (Select the TWO correct answers).
Class
Domain
Genus
Species
Kingdom
Phylum
Order
Family
Answer:
Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species
An organism’s scientific name consists of which two taxonomic groups, genus, and species. The correct options are c and d.
What are taxonomic groups?Taxonomic groups are the groups that contain different groups in which the organism are divided. These are arranged from higher to lower groups. The highest group is the kingdom.
Kingdoms are divides of the different organisms of the earth. Taxonomy is organizing different organisms in a line so, that it will be easy for their studying.
The two taxonomic groups that come in last are genus and species. Genus and species make the scientific name of the organism. The genus contains animals that are most similar to each other. Species are similar organisms, that can breed with each other.
Therefore, the correct options are c, Genus, and d, Species.

feel the inside of your elbow as you lift a book. you should feel a strong cord. what is this? what does it do?
We feel the inside of the elbow as we lift a book. We should feel a strong cord. This cord is known as Oblique cord.
What is the Oblique cord?The oblique cord is a ligament which is present between the ulnar and radius bones in the forearm region near the elbow. Oblique cord takes the form of a small, flattened band, which is extending downward and lateralward, from the lateral side of the ulnar bone tuberosity at the base of the coronoid process to the radius of a little below the radial tuberosity. The fibers in this cord runs in the opposite direction to those of the Interosseous membrane of the forearm region of the hand.
The oblique cord may simply be defined as an additional tie which is between the radius and ulna of the hand which is aiding other soft tissue structures such as the annular ligament and interosseous membrane. Additionally, the oblique cord may also prevent the anterior shearing of the proximal radius under the extreme compressive loads.

In the cells of humans and other animals, a great deal of energy is dedicated to operating a pump that transports sodium (Na+) ions out of cells and potassium (K+) ions into cells. This transport creates a chemical and electrical gradient. Maintaining the proper balance of sodium and potassium is critical to ensuring that nerve cells work properly. Nerve cells drive muscle contractions—including heart muscles—and are responsible for animals’ abilities to sense their environment and for humans’ ability to think.
Scientists gain a better understanding of the sodium-potassium pump by creating models of what the pump accomplishes. Such models are used to examine many other complex processes as well.
This model of the sodium-potassium pump illustrates the process by which sodium is pumped out of cells and potassium is pumped in. The sodium-potassium pump moves the two different ions in opposite directions.
Where in a cell does this transport process take place?
A.
nucleus
B.
cell wall
C.
cell membrane
D.

The Transport process takes place in cell membrane.
What is Transport?Cell transport describes the transportation of a material across a cell membrane. The chemical has the ability to enter or exit cells.

What role does concentration gradient play in movement across a cell membrane
in active transport?
Transport across a cell membrane is a tightly regulated process, because cell function is highly dependent on maintain strict concentrations of various molecules. When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.
