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%

How is stress stored
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.

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

Two students gather information on the global effects of plastic found in ocean waters. Student A collected information from three peer-reviewed scientific journals on the internet while student B collected information from a local newspaper.
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.

Which of these elements is not likely to be found in an organic compound?
A. carbon
B. hydrogen
C. nitrogen
D. potassium
Answer:
D. potassium
Explanation:
Potassium is not found in an organic compound. Therefore, option D is correct.
What are organic compounds?Any of a vast group of chemical compounds known as organic compounds contain one or more carbon atoms that are covalently connected to atoms of other elements, most frequently hydrogen, oxygen, or nitrogen.
The building blocks of life's components, such as carbohydrates, fats (lipids), proteins, and nucleic acids, are examples of organic substances. Petroleum and natural gas, which make up the majority of fossil fuels, are also organic molecules.
High molecular weights and complicated structures are features of organic molecules. These are usually insoluble in water but soluble in organic solvents. Potassium is not found in an organic compound. Therefore, option D is correct.

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
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.

A diagram of meiosis I is shown below.
At which stage of meiosis I does the exchange in genetic material between homologous chromosomes result in recombinant chromosomes?
prophase I
metaphase I
anaphase I
telophase I
Answer:
The correct answer is - prophase I
Explanation:
Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.
Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.
