Answer:

The correct answer is : the female chromosome

Explanation:

  • According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
  • RR is a genotype for Red eyes.
  • A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
  • In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
  • Therefore, XX must represent another trait.
  • By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
  • Given XX genotype represent a female fruitfly chromosome.

You get home from school and grab a bag of potato chips before settling onto the couch to binge watch your newest Netflix series
snow_tiger [21]

Answer:

Explanation:

Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.

While eating the chips, <u>the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution</u>. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. <u>This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis)</u> which causes dehydration in the individual and hence making the individual to be thirsty. <u>The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine </u>(because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).

Echinoderms, like sea stars, have nervous system
Y_Kistochka [10]
The answer is a simple radial nervous system.

Echinoderms do not have brains. Around their mouth, they have central rings from which nerves radially run into arms and along the body. Movement is controlled by the branches of those radial nerves.

A producer cannot make sugars in the absence of light, the correct option is A.

<h3>What are producers?</h3>

Producers, also known as autotrophs, are lifeforms that produce their own food.

They obtain energy from chemicals or the sun and transform it into usable energy in the form of sugar or food using water.

Plants and algae can produce their own food by harnessing solar energy. These organisms are referred to as producers because they generate their own food.

Thus, the correct option is A.
