The three main worm phyla are flatworms, roundworms, and segmented worms. Roundworms have a digestive tube that has two openings. Segmented worms have a closed circulatory system in which blood is enclosed in blood vessels. These are important steps in the evolutionary development of animals.

Hypothesize how the chromosomes of the parents would look compared to the chromosomes of their child?
marysya [2.9K]

During fertilization, the encounter of gametes results in the fusion of their nuclei. The nucleus of the egg cell thus formed is therefore a mixture of the two nuclei.

So the parent will only give half of his chromosomes, so the child will have 50% of his chromosomes that resemble each of his parents.

Another factor that must be mentioned is the genetic recombination between the chromosomes that occurs during meiosis of the reproductive cells. Thus, this will give a heterogeneous chromosome resulting from recombination of the two chromosomes of each of its parents, and the child will have a unique combination chromosome but keeping the alleles of both parents.

Based on the model of cellular transport, the hydrolysis of ATP and ADP provide a mechanism for
Ronch [10]

Answer:

<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>

Explanation:

During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.

For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.

<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

  • The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
  • Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

  • All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
    A semipermeable lipid bilayer makes up the cell membrane.
  • The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

  • The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
  • second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
