Biology

Question 1

Cell Membrane

Answer 1

In all cells
Separates interior of cell from outside environment
Protects and organizes cells

Question 2

Mitosis phases

Answer 2

1. Interphase
2. Prophase
3. Metaphase
4. Anaphase
5. Telophase

Question 3

Meiosis Vs Mitosis

Answer 3

Misotis results in two identical daughter cells.

Meiosis results in double, or four sex cells.

Question 4

Diploid

Answer 4

Cell that hhas paired chromosomes, one from each parent cells.

Question 5

Haploid

Answer 5

Having single set of unpaired chromosomes.

Question 6

Gamete

Answer 6

Organisms reproductive cells(sex cells)
Female gametes are ova or egg cells
Male gametes are called sperm.

Question 7

Organelle that directly proives the most amount of energy is?

Answer 7

Ribosomes

Question 8

All organelles work together to carry out?

Answer 8

Active transport

Question 9

Human circulatory system in cells

Answer 9

Cells in the circulatory system carry out the same life function for the organism as cells in the system.

Answer 10

The concentration of CO2 will remain the same inside the cell.

Answer 11

The cell membrane is capable of receiving and recognizing chemical signals

Question 12

Specific structure in a single celled organism

Answer 12

A flagellum is a structure in a single cell that makes way for movement. they can transport themselves quickly in sperm cells due to rapid movement.

Question 13

Mitosis

Answer 13

Purpose is growth and repair

Question 14

meiosis

Answer 14

purpose is genetic diversity

Question 15

diffusion

Answer 15

Substances moving from where they are in greater concentration to where they are i lesser concentration

Question 16

Diffusion what does it do

Answer 16

Regulates food, gases and waste products moving in and out of the cell.

Question 17

osmosis

Answer 17

Movement of water from where it is in greater concentration to lesser concentration

Question 18

osmosis what does it do

Answer 18

regulates hydration in and out of the cell, and in plants it controls turgor pressure.

Question 19

Active transport

Answer 19

movement of ions or molecules across a cell membrane into a region of higher concentration.

Question 20

Chloroplasts equation

Answer 20

Carbon dioxide + water — Glucose + water + oxygen

Question 21

Hypotonic

Answer 21

A hypotonic solution has a lower concentration of solutes than another solution. hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Question 22

Hypertonic

Answer 22

A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.

Question 23

Natural selection

Answer 23

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.
