Answer:
Epistasis effect result into these offspring
Explanation:
Given
spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b)
Genotype of true-breeding black spotted rabbit BBSS
Genotype of true-breeding brown solid rabbit bbss
Genotype of offspring BbSs
In normal crossing between BbSs and BbSs offspring of F1, should produce offspring in the ratio 9:3:3:1
But it does not happens in this case the simple reason could be presence of Epistasis in which the alleles assort independently but do not express themselves because of the following reasons -
a) Interaction between two or more loci thereby resulting into new phenotypes
b) An allele at one locus masks effects of other allele at one or more loci
c) Allele at one locus modifies the effects of alleles at one or more other loci

2. What happens to sedimentary rocks on Earth’s surface?
Answer:
Sedimentary rock can change into metamorphic rock or into igneous rock. ... On Earth's surface, wind and water can break rock into pieces. They can also carry rock pieces to another place. Usually, the rock pieces, called sediments, drop from the wind or water to make a layer
Explanation:
Answer:
Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. ... Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering—chemical weathering.
Explanation:
If some bacteria are resistant to tetracycline and some are not resistant, what happens when a patient is given tetracycline for an infection?
Answer:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

3. Which of the following statements best explains how the cell membrane 1 point
is selectively permeable? *
The movement of specific substances into and out of the cell is controlled by the cell
membrane
The movement of waste substances into, but not out of the cell is controlled by the
cell membrane
The cell membrane is inflexible and cannot control the movement of substances into
and out of the cell
The cell membrane does not surround the cell so it plays no role in the movement of
substances
Answer:
The movement of specific substances into and out of the cell is controlled by the cell membrane.
Explanation:
The cell membrane is permeable, so it allows for the passage of substances both into and out of the cell. It is also selective, so only specific substances can enter and exit the cell.

What is an exothermic reaction?When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.
The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.
Therefore, the correct option is C.

Explanation:
the process which takes place in guard cells but not in other epidermal cells is?
Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Difference in guard and epidermal Cells:Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.
Photosynthesis does not take place in epidermal cell because:The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories
Answer:
D. 367
Explanation:
If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.
What is food energy?Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.
The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
To find the total calories, multiply the given biomolecules grams with their calorie count.
= 42 × 4 + 7 × 9 + 34 × 4
= 168 + 63 + 136
= 367 calories
Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

If you have a hamster with long fur, what possible genotypes could the hamster have?
Answer:
Ll, Ll, LL
Explanation:
So, there is one thing we must remember to answer this:
1# dominant genes(long fur) are expressed over reccesive genes(short fur)
Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. Long fur - Ll, lL
Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. Long fur - LL
Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll
