In certain plants, tall is dominant to short. If a heterozygous plant is crossed with a homozygous tall plant, what is the probability that the offspring will be short? A) 1
B) 1/2
C) 1/4
D) 1/6
E) 0

Answers

The answer is E) 0.

If:
A - dominant allele,
a - recessive allele,

then:
AA - dominant homozygous (tall),
aa - recessive homozygous (short),
Aa - heterozygous (tall).

A heterozygous plant (Aa) is crossed with a homozygous tall plant (AA):

Parental generation:         Aa     x    AA
F1 generation:           AA     AA     Aa     Aa

All of the offspring is tall (AA or Aa), since tall is dominant to short.
There is no chance for offspring to be short (aa).

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct?Brody is correct because the wave involves an input of energy.
Ethel is correct because energy is not carried from one place to another.
Brody is correct because the pattern repeats.
Ethel is correct because the motion has no pattern.

Answers

Ethel is correct because energy is not carried from one place to another.

What is a wave?

A wave is a disturbance along a medium which transfers energy. We have to know that wave moves from place to place and must transfer energy in the process.

In this case, Ethel is correct because energy is not carried from one place to another as Broody waves his hand from side to side.

When do the sister chromatids line up at the equator of the cell?a. metaphase
b. anaphase
c. prophase
d. telophase

Answers

A) metaphase (:

prophase is when chromatin condenses into chromosomes then the centrosomes move to opposite ends of the cell, anaphase is when sister chromatids separate and then are pulled towards the centrosomes and telophase is the splitting of the cell (v v briefly explained) 

Final answer:

Sister chromatids line up at the equator of the cell during the metaphase stage of cell division. This arrangement is essential to ensure each new cell receives an exact copy of each chromosome. The next stage, anaphase, involves the separation of these chromatids.

Explanation:

The sister chromatids line up at the equator of the cell during the metaphase stage of cell division, whether it is mitosis or meiosis. The stage where sister chromatids align in the middle of the cell is integral to the process as it ensures that each new cell will receive one copy of each chromosome. In the next phase, anaphase, these chromatids are separated and drawn to opposite ends of the cell. Thus, the correct answer to your question is (a) metaphase.

Radium has a half-life of 1,620 years. In how many years will a 1 kg sample of radium decay and reduce to 0.125 kg of radium?3,240 years

6,480 years

4,860 years

1,620 years

Answers

4680 years

1 x .5 = .5

.5 x .5 = .25

.25 x .5 = .125

You multiplied 3 times, so 3 times 1,620 is 4,680.
