Pollination is an example of ________.
Karolina [17]

The correct answer is C. An ecosystem service

Explanation:

In ecology, an ecosystem service refers to processes or elements that are part of the natural environment but besides this represent benefits for humans, this includes organisms and processes involved in the decomposition of waste and also pollination. Pollination is an example of an ecosystem service because, in pollination insects, birds and other organism or even wind transfer pollen which makes possible plants fertilization and this is essential for crops in agriculture, which means humans benefit for pollination and therefore this is an ecosystem service.

e-lub [12.9K]

Answer:

The correct answer is fungi.

Explanation:

Fungi are the eukaryotic organism but they can be present in unicellular and multicellular form. They are different from plant, animals, and bacteria. They are heterotrophic organisms and do not conduct photosynthesis. Their cell wall is made up of chitin.  

Most of the fungi are saprophytes which means they take their nutrition from the dead and decaying organism. So fungi play an important role in clearing the waste organic material from the environment so they help in bioremediation. All members of fungi comes under a separate kingdom fungi.

Each orientation of chromosomes produces gametes with the same genetic information from each parent.
oksano4ka [1.4K]

Answer: a) true

Explanation:

The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.

The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.

During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.

Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>
