Hybridization _____.

Biology
2 answers:
lana66690 [7]3 years ago
8 0

Answer:

usually produces offspring that cannot reproduce

Explanation:

Hybridization is the process of crossing two organisms usually of different species, genus or families but of desirable characters to produce organisms known as hybrids.

<em>Hybrid organisms combine the characteristics of both parents and because of the difference in genetic composition of the parents, they are often sterile and hence, cannot reproduce.</em>

<em>Therefore, </em><em>hybridization usually produces offspring that cannot reproduce.</em>

Answer:

The correct answer is: c) usually produces offspring that cannot reproduce.

Explanation:

Hybridization, also knowns as selective breeding, is an <u>artificial process</u><u> that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits</u>.

Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.

Option A is incorrect because hybridation does not occur in nature, it is an artificial process.

Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).

Option D is correct because an important amount of hybrids are sterile (for example: mules).

Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.

Why are the processes of oxidation and reduction important to cellular respiration?
DiKsa [7]

Answer:

During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose. This produces the majority of the energy released in cellular respiration

Describe one way in which ribosomes interact with organelles. How would having a larger number of ribosomes benefit a cell? In y
tino4ka555 [31]

Answer:

Ribosomes are the machinery of protein synthesis in the cell. They are associated with different organelle of the cell. They are also found free-floating in the cytoplasm of the cell.

The organelle which ribosomes interact are plasma membrane in prokaryotes and endoplasmic reticulum(ER) in eukaryotic cell. Ribosomes are present on the surface of the ER and helps in protein synthesis in the ER. In prokaryotes, there is no ER so it is associated with plasma membrane and perform protein synthesis.

The specialized function of ribosome is to perform protein synthesis and these proteins are necessary for cell because protein are important to make enzymes that regulate the metabolism of the cell. So if protein synthesis stops cell will not able to perform important metabolic activities to survive and it will die.

Having a large number of ribosomes benefits cells because it fastens the protein synthesis process in the cell. So large amount of protein can be produced in less time.

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve
kkurt [141]

Answer:

The correct matches are:

  1. In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
  2. In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
  3. In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
  4. In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

  • Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
  • Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
  • Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
  • Since, NADH is donating its H+, it is being oxidized to NAD+.

Heavy metals work by select one: a. rupturing the cell membrane. b. inactivating proteins. c. binding to dna. d. dissolving the
Lubov Fominskaja [6]

Heavy metals work by dissolving the cell wall.

Sterilization describes a method that destroys or gets rid of all styles of microbial existence and is done in health-care facilities with the aid of bodily or chemical strategies. Using a physical or chemical method to smash vegetative pathogens is: disinfection. using chemical marketers immediately on uncovered frame surfaces to damage or inhibit vegetative pathogens.

The term heavy metallic refers to any steel chemical detail that has a notably excessive density and is poisonous or toxic at low concentrations. Examples of heavy metals encompass mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb). Even though the beginning of the time period heavy metallic is broadly attributed to novelist William Burroughs, its use dates nicely again into the nineteenth century, while it cited cannon or to electricity greater usually. It additionally has been used to classify certain elements or compounds, as in the phrase heavy metallic poisoning.
