In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an

independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is the C gene. At this locus, the genotype C- permits expression of pigment from genes B and D. The cc genotype, however, prevents expression of coat color and results in albino rats. For each of the following crosses, determine the expected phenotypes and their ratio in progeny:Part ABbDDCc x BbDdCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part BBBDdcc x BbddCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part CbbDDCc x BBddCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part DBbDdCC x BbDdCCExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).

How does the movement of particles of matter change when temperature increases?
saveliy_v [14]

Answer:

Increases

Explanation:

The movement of particles of the matter increases with the increase in temperature.

The particles gain kinetic energy with increasing temperature and move in faster rate.

<u>For example:</u> When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.

Hence, the correct answer is "increases".

If a deer eats grass, what percentage of energy will the deer acquire from the grass? 0. 1 percent 1 percent 10 percent 100 perc
Lemur [1.5K]

The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.

  1. In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another.
  2. The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.

<h3>What is the position of deer in the food chain?</h3>

The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.

Thus it is clear that 10 percent of energy will the deer acquire from the grass.
