The statements that are associated with cell theories are
A - Cells are the basic units of structure in living things.
B - Cells are the basic units of function in living things.
C - Cells come from pre-existing cells.
<h3>Definition of cell</h3>
The cell was defined as the basic unit of life - both structural and functional as all living matter is made up of cells. And these cells arise from living cells and not from non-living matter.

The correct answer among the choices listed is option 4. Infections generally result in an increase in the number of leukocytes or white blood cells. An increase in the number of white blood cells in circulation is called leukocytosis. This increase is commonly caused by inflammation.
Answer:
G1-preparation for DNA replication
G2-preparation for mitosis
Explanation:
Cell cycle is a process that can be divided into two major phases: interphase and mitotic phase (division). Interphase is than subdivided into G1, S and G2 phases while mitotic phases consists of prophase, metaphase, anaphase and telophase.
Phases in interphase:
- G1 or Gap 1 is characterized by cell growth (cell becomes much larger), synthesis of molecules and organelles copying.
- S phase is characterized by DNA replication
- G2 phase or Gap 2 phase is phase in which cell makes more proteins and organelles and prepares for mitosis

Answer:
- 25 tall individuals, TT
- 50 medium individuals, Tt
- 25 short individuals, tt
Explanation:
<u>Available data</u>:
- The size of this species was determined by a single gene
- TT- Tall
- Tt- Medium
- tt- Short
- Total number of individuals in the progeny, N = 100
There are three phenotypes and only one gene, so it seems that this is an example of incomplete dominance, where the medium-size is the intermediate form between tall-size and short-size.

Parentals) Tt x Tt
Gametes) T t T t
Punnett square) T t
T TT Tt
t tT tt
F1) 1/4 = 25% TT, tall
2/4 = 1/2 = 50% Tt, medium
1/4 = 25% tt, short
100% of the progeny ------------ 100 individuals
25% Tall, TT ------------------------X = 25 individuals
50% Medium, Tt -------------------X = 50 individuals
25% Short, tt ------------------------X = 25 individuals
