zheka24 [161]3 years ago
4 0

Answer: There are three stages

Explanation: Cellular respiration occurs in the cells of all living things, both autotrophs and heterotrophs. All of them burn glucose to form ATP. The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport.

Free earlobes are dominant over attached earlobes. What is the probability that a woman with attached earlobes (homozygous reces
AVprozaik [17]
<h2>The correct answer is explained below:</h2>

Explanation:

  • According to the question, free ear lobes are dominant over attached ear lobes.
  • Let the allele for free ear lobes be represented by F.
  • Let the allele for attached ear lobes be represented by f.
  • The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
  • The gamete produced by the woman is: f.
  • The genotype of the heterozygous man (father) with free earlobes is: Ff.
  • The gametes produced by the man are: F and f.
  • Mating the man with the woman we get the following offspring,

                                        F                                            f

                           f           Ff                                          ff

          Phenotype      Free ear lobe                   Attached ear lobe

  • The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
  • The probability that the parents would produce children with attached ear lobes is = \frac{1}{2} .

During depolarization, which of the following statements about voltage-gated ion channels is TRUE
Wewaii [24]

Answer:

In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.

Explanation:

Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.

  • Na⁺  is a predominantly extracellular cation.
  • K⁺ has a high intracellular concentration.

This distribution occurs when the membrane potential is at rest, with a negative intracellular value.

Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.

While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.
