Answer:
The correct answer is -3/16
Explanation:
The cross between BBss and bbSS In cocker spaniels will form gametes that are - Bs and bS. As it is given that black coat color ( B) is dominant over red ( b), and solid color ( S) is dominant over spotted ( s) then f1 gen would be :
Bs Bs
bS BbSs BbSs
bS BbSs BbSs
Now F2 generation;
BS Bs bS bs
BS BBSS BBSs BbSS BbSs
Bs BBSs BBss BbSs Bbss
bS BbSS BbSs bbSS bbSs
bs BbSs Bbss bbSs bbss
Here black-spotted that is possible only in two cases, BBss or Bbss, are 3/16
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.

How many grams of LiCl are in 235.0 mL of 1.80 M lithium chloride solution?
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

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.
Explanation:
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%

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 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.

Cystic Fibrosis is a genetic disease of the lungs caused by a recessive allele. A man with Cystic Fibrosis marries a woman who does not have Cystic Fibrosis, but her father had the disease. What is the probability of the couple having a child that has Cystic Fibrosis?
Answer:
There is no chance of child with the disease
Explanation:
As cystic fibrosis is a recessive disease homogeneous condition is required in child to have the disease . Since the mother is not suffering from the disease & there is no history in her family so she does not have the gene for cystic fibrosis
