Answer:
When an egg and sperm having 46 chromosomes similar to the body cells, their fertilization produces offsprings or children with 92 chromosomes which are double number of chromosomes as compared to parent cell. So they are not similar to parents. As we know that fertilization is the process of fusion of gametes and paring up of chromosomes. The offsprings are different from their parents in having more chromosome sets.

Explanation:
If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
a) true
b) false
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".

Short tails (T) are dominant to long tails (t). What is the probability of a long-tailed mouse in the cross Tt x tt?
25%
50%
O 75%
O 100%
Answer:
50%
Explanation:
if you do a punnett square you get two Tt and two tt. so two tt is half, which means half will be long-tailed tt, so 50%
50% of the mouse offsprings will have long tail.
According to this question, a gene coding for tail length in mouse is involved. The allele for short tails (T) are dominant to long tails (t). In a cross between Tt (short tail) × tt (long tail), the following gametes will be produced by each parent: Tt - T and ttt - t and tCrossing these gametes in a punnet square (see attached image), the following offsprings of mouse will be produced: Tt, Tt, tt and tt. Tt (2) = Short tail mice (50%)tt (2) = long tail mice (50%)Therefore, 50% of the mouse offsprings will have long tail.Learn more at: https://brainly.com/question/478887?referrer=searchResults

Which statement best describes the reliability of the students' research?
A
Student A's research is more reliable because it was gathered from peer-reviewed journals.
(Choice B)
B
Student B's research is more reliable because it came from a single source.
(Choice C)
C
Student B's research is more reliable because newspapers can only publish current research.
(Choice D)
D
Student A's research is more reliable because it came from the internet.
Answer:Student A’s research is more reliable because it was gathered from peer-reviewed journals.
Explanation:
In any experiment, reliabilty and validity is very important. The best statement that best describes the reliability of the students' research is that Student A's research is more reliable because it was gathered from peer-reviewed journals.
Reliability is simply known as an individual obtaining the same answer through the use an instrument to measure something more than once.It is the degree to which research method gives stable and consistent results.
Reliability often deals with consistency of a measure. Ita types are test-retest reliability, internal consistency, and inter-rater reliability.

The net movement of water takes place from the ____ side to the ____ side of the membrane.
The net movement of water takes place from the Hypotonic side to the Hypertonic side of the membrane.
Where does the net movement of water take place?The net Action of water is in the order of risen solute concentrations.
An easy way to imagine this rule is just that the net water move in an area of high water concentration to an area of lower water concentration.
Thus, The net movement of water takes place from the Hypotonic side to the Hypertonic side of the membrane.

Summarize for prophase?
Answer:
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
the producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
Answer:
600 kcal
Explanation:
In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.
Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

1
Show Your Work
Answer:
Mass of LiCi = 17.9352 gm
Explanation:
Given:
Volume of LiCi = 235 ml
Molarity = 1.80 M
Find:
Mass of LiCi
Computation:
Atomic mass of LiCi = 6.9 + 365.5 = 42.4 gm
Mole(n) = Weight / Atomic mass
1.80 = [W / (42.4 x 235)]1000
Mass of LiCi = 17.9352 gm

in a rock released?
Answer: The stress builds up in rocks. However, rocks eventually break, and the stored stress is released as energy in the form of earthquakes. ... The energy released during an earthquake migrates away from the focus of the earthquake (location of the first break of the rocks) as waves. These waves are called seismic waves.

If you cross a white-eyed female (ww) to a red-eyed male (WY) Drosophila fly, you will see red-eyed females and white-eyed males in the F1 generation. If you cross an F1 red-eyed female to an F1 white-eyed male, what is the approximate percentage of total progeny in the F2 generation that are white-eyed males
Answer:
25%
Explanation:
ww gives white-eye female
WY gives red-eye male
ww x WY
F1: Ww wY Ww wY
Ww - red-eye female
wY - white-eye male
Crossing the two F1
Ww x wY
F2: Ww WY ww wY
Remember that white-eye male = wY
Percentage of wY = 1/4 or 25%
Hence, the percentage of progeny in the F2 generation that would be white-eye males = 1/4 or 25%
