One of the seed banks has been storing seeds of a rare and endangered plant to keep the seeds fresh.120 of the seeds of this pla

lianna [129]

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.

All living organisms share characteristics such as DNA, the molecule that passes information between generations; metabolic proc

Naily [24]

Answer:

Biological evolution

Explanation:

Biological evolution is defined as the formation of complex organisms from single ancestral type over a large time period. Evolution believes that all living organisms descended from a common ancestor but not without modification.

There are several evidence to support the theory of evolution including morphological evidence, paleontological evidence, biochemical evidence, among others.

The similarity in the structure and components of DNA of all living organisms is one of the evidence pointing to the fact that living organisms might truly have been from a common ancestor. In addition, all living organisms tend to use ATP largely as their source of energy, giving further credence to evolution theory.

2. Genotype.

3. Allele.

4. Meiosis.

5. Gametes.

6. Genome.

7. Mitosis.

8. Homologous Chromosomes.

9. Crossing over.

10. Gremlins cells.

11. Zygote.

12. Somatic cells.

13. Independent assortment.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

The various terminologies used in the field of genetics includes;

1. Sex chromosomes: The chromosomes that determine your biological sex -X and Y.

2. Genotype: The set of alleles an organism inherits.

3. Allele: Versions of a gene that arise through mutation.

4. Meiosis: Cell divisions that occurs in sex cells.

5. Gametes: Egg and sperm cells.

6. Genome: The complete set of genes in an organism.

7. Mitosis: Cell division that occurs in all body cells.

8. Homologous Chromosomes: The matching chromosomes a person inherits from their mother and father.

9. Crossing over: A process that increases genetic diversity during meiosis.

10. Gremlins cells: Cells that divide to produce gametes.

11. Zygote: The cell formed when an egg and sperm meet

12. Somatic cells: Body cells (hair, skin, brain, bone, etc.)

13. Independent assortment: The random lining-up of homologous pairs at the cell's middle.
