Answer:

1. Sex chromosomes.

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.

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral
dimaraw [331]

Answer:

In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species

Explanation:

A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

Which structure ATP or ADP contains more stored energy? Where is the energy stored
koban [17]
The ATP is the adenosine triphosphate. The ATP molecule has the three phosphate molecules attached with the adenosine. The ADP is the adenosine diphosphate. It has two phosphate groups. The number of phosphate molecules is responsible for the amount of energy in bonds. Hence the ATP molecule has the three phosphate group hence it has more stored energy as compared to the ADP molecule which has two phosphate group.
