<h2>Answer:</h2>

The replication of chromosome is followed by meiosis.

<h2>Explanation:</h2>

Before meiosis really starts, the DNA that is bundled into chromosomes must be completely duplicated. Past to replication, a cell of germ contains two duplicates of every chromosome, a maternal copy and a fatherly copy. The maternal and fatherly homologs depict the maternal and fatherly hereditary contribution to every cell and guarantee that every cell has a half hereditary make-up originating from each parent. These two chromosomes are autonomous yet fundamentally the same as and are named homologs of one another.  

DNA replication happens in a similar manner as it does during mitosis. After replication, the homologs are multiplied, and every chromosome presently has a homologous pair.

The type of reproduction that is most often used by multicellular organisms is.
Nezavi [6.7K]

Meiosis is involved in the formation of the gametes of multicellular organisms.

<h3>How do multicellular organisms reproduce?</h3>

Both plants and animals reproduce by developing new individuals, through gametes or reproductive cells.

<h3>Characteristics of multicellular organisms reproduction</h3>

  • Many multicellular organisms always arise from a single cell called a zygote, the result of the union of two gametes (female and male).

  • The zygote subdivides rapidly throughout gestation, forming the entire body of the creature that, from its birth, begins to grow.

Therefore, multicellular organisms reproduce by means of certain types of reproductive cells that are generated and take care of building a complete new individual.

yarga [219]

Answer:

I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>

Explanation:

I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.

I found rods, and some are gram positive and long. They others are gram negative and very small and short.

The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>

The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.

The body can be invaded by pathogens , which are harmful microorganisms that cause infection diseases. The body then initiates a
pochemuha

Answer:The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
