During interphase, the dna has replicated so the chromosomes that appear during prophase are actually doubled. the structure the

y form is called a tetrad. during mitotic anaphase, the tetrad splits moving a copy of each homologous chromosome to each daughter cell. this produces two daughter cells identical to each other and identical to the parent cell. this isn't what happens in anaphase i of meiosis, however. explain.

nexus9112 [7]

The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.

<u>Asexual Reproduction:</u>

This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.

  • The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
  • Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
  • Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.

<u>Sexual Reproduction:</u>

  • A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
  • That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
  • These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.

Botulism is caused by ingestion of a proteinaceous exotoxin; therefore, it can easily be prevented by
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.

The diagram shows structures found in a seed plant. What is the function of labeled X
Alja [10]

Question is incomplete. Complete question has been attached.

Answer:

carries food produced by leaves

Explanation:

The diagram is a cross section of stem of a dicot plant, specifically <em>Hypericum perforatum</em>. It shows all the structures present in the stem like xylem, phloem, pith, cortex etc. The structure labelled X is phloem. It is present between xylem (stained red) and peripheral cortex. Phloem is responsible for conduction of sugars and nutrients in the plant thus it carries the food produced by leaves. Together xylem and phloem make the vascular tissue which surrounds the central pith (stained bluish-green).
