Answer: Tissue

Explanation:

Tissue is a group of similar cells that work together to serve a common function. Tissues that work together are grouped and called organs which futher makes up a system. The digestive system for instance is made of different organs such as intestine, stomach which works together to digest food.

Each digestive organ in the digestive system has its own unique tissues, with each tissue having its own unique cells.

Aleks [24]

Answer:

No.

Explanation:

Based on the punnets square (assuming that eye color is a one gene trait in this question) There is a 75% chance they would have a child with brown eyes and a 25% chance that the child would have blue if the father is heterozygous. Theoretically the father could be heterozygous and still have 11 brown eyed kids. This just means that the Dad always passed down his dominant gene.

Using an example (from class or another) and one of the forms of evolution, explain in a short paragraph the true scientific mea

vitfil [10]

There are basically three types of evolution divergent, convergent and parallel evolution.

a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.

b) Convergent Evolution – In this evolution, different species of organisms living in a similar biosphere start share common traits in the form of analogous features. For example – Whale and fish are not closely related species but they both have fins which are different in structure but have the same function.

c) Parallel evolution – In this evolution the similar characteristics between the two set of organisms are maintained though the two species continue evolving separately. For example - marsupial mammals of Australia and the Placental mammals

Match the call structure with the best description. Each cell structure matches with exactly one description.

Makovka662 [10]

Answer:

Please find the cell structure with their best descriptions below

Explanation:

1. Capsule: Capsules are one of the Glycocalyx that firmly attaches to the cell surface and helps the cell avoid phagocytosis.

2. Slime layer: Slime layer is the other Glycocalyx that is loosely attached to the cell surface and helps the cell prevent dessication.

3. Flagella: The flagella is a long whip-like cell structure found in bacteria and some protists and principally used for moving.

4. Conjugation pilus: Conjugation pilus is a cell structure in bacteria that is used to transfer DNA to another bacteria cell.

5. Fimbriae: Fimbriae is a short, bristle-like protein that project from cell surface and help cells attach to surfaces of other cells.

6. Cell wall: Cell wall is a cellular structure found in plant cell and bacteria cells, whose function is to protect cells from harsh conditions and helps maintain cell shape.

7. Cell membrane: The cell membrane controls passage of substances into and out of the cell.

8. Cytoplasm: The cytoplasm is a gelatinous material found inside the cell.

9. Inclusions: Inclusions are structures in cells that formed from the deposits of nutrients.

10. Endospores: Endospores are structures that protect bacterial genome in a dormant state under adverse environmental condition.

11. Ribosomes: Ribosomes are organelles in a cell that makes polypeptide (protein).

12. Mycolic acid: Mycolic acid is a waxy molecule (long fatty acid chain) that is found in some gram positive bacteria and associated with their cell wall.

13. Nucleoid: A nucleoid is a region in prokaryotic cell where chromosomal DNA and DNA-associated proteins are concentrated.

14. Pili: Pili is similar to the Fimbriae but longer and contain less numerous protein appendages than fimbriae used in attachment.
