differentiate between Angiosperms and gymnosperm
Answer:
Angiosperms are vascular plants bearing the seeds in fruits or mature ovaries whilst gymnosperms are other types of the plant which bears the seeds directly on the sporophylls but without any cover.
Explanation:
Examples of gymnosperms include cypress,pine, redwood, spruce and ginkgo.
Examples of angiosperms include apple, banana,peach, cherry and orange.
Also, angiosperms are seeds producing flowering plants whose seeds are enclosed within an ovary.

The cell walls of a plant consist mostly of cellulose, a carbohydrate, which provides a strong structure. The cell membrane gets its structure primarily from lipids, and embedded proteins allow for material transport.
Answer:
Common to all plant species, the cell wall is the tough outer coat that protects the plant cell. The cell wall is mostly carbohydrate‐based, comprising three major classes of polysaccharides: cellulose, hemicellulose and pectin. There are also important structural proteins as well as phenolic and aliphatic polymers.

A mutation to the p53 gene can cause what type of disease?
-Cancer since the delay in the cell cycle is disrupted.
-Nondisjunction causing an abnormal number of chromosomes.
-Cystic fibrosis due to a mutation in the gene that codes for a specific protein.
-Sickle cell causing abnormally shaped red blood cells.
Answer: A mutation to the p53 gene can cuase cancer since the delay in the cell cycle is disrupted.
A mutation to the p53 gene can cause this type of disease: Cancer since the delay in the cell cycle is disrupted.
A cell cycle is as an ordered sequence of events that takes place within a living cell as it grows and divide into two new daughter cells.
Cancer can be defined as the uncontrolled division of certain body cells, which then invade the surrounding tissues and interfere with the normal functioning of the body.
Some examples of cancer are:
Breast cancer.Prostrate cancer.Carcinoma.A tumor can be defined as an abnormal mass of tissue formed when various body cells grow and divide more than its required or fail to when necessary (required).
Thus, it usually degenerate into cancerous growths (cancer).
In conclusion, it is caused by exposure to extremely dangerous radioactive substances such as gamma ray, uranium etc.

What makes amino acids unique from one another
Answer:
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. ... Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached.
The R-groups are different and unique
The R group makes amino acids unique from one another. The correct option is C.
What are amino acids?The R group, carboxylic acids, and amine groups are the building blocks of amino acids, which are tiny molecules. They serve as the foundation for proteins. The twenty different kinds of amino acids.
Amino acids are distinct because they contain three groups. It distinguishes itself from others due to its size, form, and membership in the R group. The R group gives the protein a distinctive shape that has a significant impact.
While the rest of the amino acid structure is the same across all types of amino acids, the R group varies. Therefore, the R group can be used to distinguish between amino acids.
Thus, the correct option is C. the R group.

Green
Blue
Yellow
Red
Answer:
Blue light
Adding 10-20% blue light allowed plants to grow much healthier, with a compact appearance. There is also far-red light which is has wavelengths that are lower than normal red light–similar to near-infrared wavelengths. Far-red light helps the plants produce greater yields.
