The sodium-potassium pump establishes concentration gradients:

Biology
1 answer:
irinina [24]3 years ago
3 0

Answer:

The correct answer is C

Explanation:

The sodium-potassium pump is maybe the most well-known pump in biology, and rightly so as it is extremely important for life.

This pump functions by hydrolysis of ATP for energy, and by doing so <em>pumps 3 Na+ molecules to the extracellular space and 2 K+ molecules to the intracellular space.</em> This creates a higher sodium concentration outside the cell and a higher one inside the cell.

This gradient has several functions, such as helping maintain electrochemical neutrality and providing the adequate gradient of cations for signal transduction in neurons, to name a few.

hammer [34]

Botulism can easily be prevented by boiling food prior to consumption.

<h3>What is Botulism?</h3>

Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.

Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.

It can only be prevented by taking the proper boiled food prior to consumption.

The complete question is as follows:

  • boiling food prior to consumption.
  • administering antibiotics to patients.
  • not eating canned food.
  • filtering food.
  • preventing fecal contamination of food.

Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.

True [87]

Answer:

Gene: The hereditary material made up of alleles.

Alleles: The alternative forms of a gene.

Dominant: An allele or trait that masks the effect of recessive allele or trait.

Recessive: An allele or trait that gets suppressed by the dominant allele or trait.

genotype: The genome of a particular organism of the genes which make up an organism.

phenotype: The physical traits or characteristics of an organism.

test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.

law of independent assortment: Alleles of different genes get assorted independently into gametes.

law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.

product rule: Independent evens can be calculated by multiplying the independent probabilities.

Addition rule: The probability which shows that one event would occur in a mutually exclusive event.

co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.

incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.

Why is it important that root hair cells have high ion concentration?
andre [41]

Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
