Describe the function of each organelle.
Elis [28]

Answer:

Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles

Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.

Ribosome: A small particle in the cell that can make proteins.

Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.

Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.

Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.

Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)

Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).

Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.

Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.

Gene testing is foolproof since it scans the building blocks of humans. Please select the best answer from the choices provided.
Harrizon [31]

False

reason -

Gene testing is not full proof as there are  possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof

A farmer is experimenting with pea plants. If the farmer crosses two pea plants with round and yellow peas (genotype RrYy) how m
seropon [69]

Answer:

The genotype of both parents is RrYy.

The possible types of gametes would be RY, Ry, rY, and ry.

The cross would produce offspring that can have one out of four types of phenotypes:

  • Round and yellow seeds (1 RRYY+ 2 RrYY +2 RRYy + 4 RrYy) = 9/16
  • Wrinkled and yellow seeds (3 rrYy) = 3/16
  • Round and green seeds (1 RRyy + 2 Rryy) = 3/16
  • Wrinkled and green seeds (rryy) = 1/16

Thus, one out of 16 offspring would have wrinkled and green seeds.
