A human body cell has 46 chromosomes. Female egg cell has 23 chromosomes.

Further Explanation:

Sexual reproduction is the major method of reproduction in a variety of microscopic organisms. It almost includes all the plants and animals. The main process in sexual reproduction is:

meiosis
fertilization

Fertilization is a process of the fusion of gametes which are sperm and egg results in the diploid zygote. In meiosis ploidy level of germ cell get halved. Meiosis involves crossing over in between the non-sister chromatid of the homologous chromosome thus leads to genetic variation.

After fertilization, meiosis occurs and crossing over takes place which transfer the genetic information from parents to offspring. The human cell consists of 46 Chromosomes. Therefore, the female egg cell would have a set of 23 chromosomes. Also, the male have a set of 23 chromosomes. By fertilization they give rise to a set of 46 chromosomes in the offspring.

How is a mantle plume (hot spot) different from volcanoes in the Ring of Fire? How are they similar? Give one specific example o

riadik2000 [5.3K]

The difference between a hot spot volcano and the volcanoes from Ring of Fire can mainly be seen in the way of formation and functioning. The hot spot volcanoes are far away from any tectonic plate boundary and they manage to penetrate the crust over them and come out on the surface to usually create volcanic islands. The activity of the volcanoes from the Ring of Fire depends directly from the activity between the bordering tectonic plates, and as the borders move over time, the volcanoes stop existing, and new ones rise in the direction where the boundary moves.

The similarity can be seen in the type of eruptions, and that usually both types of volcanoes form volcanic islands.

Example for a hot spot volcano is Mauna Loa on Hawaii.

Although Arroyo does not mention the term "watershed," it was discussed in the unit as being closely related to and impacted by

rusak2 [61]

Answer:

Arroyo integrated the term “watershed“ by saying that Oxfam and Swiss Re with the Rockefeller foundation are helping farmers building hillside terraces to conserve water and they are also providing for insurance when the droughts do come.Water shed relates to drought and heat because it will suffer and there would be less water to fill surface water resources and less water to make its way through the earth and into groundwater reservoirs.

How is a virus different from a bacterum?

I am Lyosha [343]

(it would be helpful if you marked me as brainliest) :)

Answer:

Viruses are tinier than bacteria. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells.

What happens when a water molecule is added to a macromolecule? What is the name of this reaction?

lara31 [8.8K]

The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.
