Answer:
The correct option is E..all of these
Explanation:
This is because all living exhibit functional characteristics which are movement, respiration, nutrition, irritability, growth, excretion, respiration and death. This characteristics are indication that organisms are living things.
Growth: it is the increase in size of organisms. All living organisms grow, they increase in size , from zygote to adulthood.
Metabolism...all living organisms excreate, they absorb nutrients and remove unwanted waste products and undigested good like sweat, urine e.t.c.

Which best describes independent assortment?
In metaphase 1, chromosomes from the mother and father line up on opposite sides of the cell.
In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.
Portions of each chromosome switch sections in the mother’s and father’s chromosomes.
Portions of each chromosome break off and reattach to the original chromosome.
Answer:
In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.
Explanation:
In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).

Which line of defense includes active immunity?
O first
O second
O third
O fourth
Answer:
The second line of defense.
Explanation:
In our bodies the second line of defense includes active immunity. It contains non-specific immune responses, but yet still contains specific responses for certain things such as inflammatory and fevers.
Third line of defense includes active immunity. The correct option is C.
What are lines of defense?The first line of defense consists of chemical and physical barriers that are constantly ready to defend the body against infection.
Your skin, tears, sputum, cilia, stomach acid, urine flow, 'friendly' bacteria, and white blood cells called neutrophils are examples of these.
The second line of defense assists administration in effectively managing risk and controls.
Organization develops multiple risk management and compliance functions to assist in the development and/or monitoring of first-line controls.
Immune cells that specifically target antigens are the third line of defense. B-cells and T-cells, all white blood cells, are immune cells that play a role in the third defense line.
Antibodies are produced by B-cells. T-cells aid in the identification of pathogenic cells and the destruction of those cells.
Thus, the correct option is C.

A tall plant (TT) is crossed with a short plant (tt). What is the genotype?
Use a punnett square to solve.
OTT: 2/4; Tt: 2/4;tt: 0/4
TT: 2/4; Tt: 1/4;tt: 1/4
TT: 0/4; Tt: 4/4;tt: 0/4
TT: 1/4; Tt: 2/4;tt: 1/4
Answer: TT: 1/4; Tt: 2/4;tt: 1/4
Explanation:
The Punnett square is a diagram that is used in the predictions of genotypes. In this scenario, if we have a tall plant (TT) is crossed with a short plant (tt), after using the Punnett square, the genotype that we will get are as follows:.
TT, Tt, Tt, tt
Therefore, the correct option is option D "TT: 1/4; Tt: 2/4;tt: 1/4
Answer: TT: 1/4; Tt: 2/4;tt: 1/4

A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh-positive is a trait that shows simple dominance over Rh-negative. Which of the following is a possible phenotype for the father?
A) A negative
B) O negative
C) B positive
D) AB negative
Answer:
The correct answer is - C) B positive
Explanation:
In the given question is the man has B positive blood group with two offspring a girl with type O positive and a son who is type B negative. In ABO blood group A and B if present together they express in offspring if present together.
Here the difference in the Rh factor only as the blood group O has no antigen on its surface therefore the most possible phenotype for the father as he has son with B negative and a daughter with O positive.

Genetics Problem Solving Chapter 25
Answer:
See the answer below
Explanation:
1. Tt x Tt
TT Tt Tt tt
Assuming that T is dominant over t:
Genotype ratio = 1TT:2Tt:1tt
Phenotype ratio = 3:1
2. Rr x Rr
RR Rr Rr rr
Assuming that R is dominant over r:
Genotype ratio = 1RR:2Rr:1rr
Phenotype ratio = 3:1
3. Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg
Gg x Gg
GG Gg Gg gg
Genotype ratio = 1GG:2Gg:1gg
Phenotype ratio = 3:1 (green ratio the other color)
4. Assuming that green (G) is dominant over the other color (g) as above:
homzygous green plant = GG; heterozygous green plant - Gg
GG x Gg
GG Gg GG Gg
Genotype ratio = 1GG:1Gg
Phenotype ratio = 100% green
5. Assuming that tall (T) is dominant over short (t)
Homzygous tall plant = TT
short plant = tt
TT x tt
Tt Tt Tt Tt
Genotype ratio = 100% Tt
Phenotype ratio = 100% tall

What did scientists believe was contributing to the depletion of the ozone layer and why?
CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.
