Answer:

Because plants need carbon dioxide more than any other compound/element. Also, heat doesn't make much of a difference in a plants growth or production. It's sunlight that makes a difference.

Carbon dioxide is considered as the most important greenhouse gas due to its abundancy in the atmosphere.  

• In the atmosphere, climate change is mainly an issue due to high concentration of carbon dioxide in the atmosphere.  

• This overload is because of the burning of fossil fuels and burning of forests.  

• Apart from carbon dioxide there are many heat trapping gases like water vapor and methane, however, carbon dioxide is putting us at greater threat due to irreversible modifications it takes place if it continues to gather at such rate in the atmosphere.  

• Carbon dioxide has contributed more to climate change than any other greenhouse gases between 1750 and 2011.  

• The other gases like methane possess more potent heat trapping tendency per molecule in comparison to carbon dioxide, however, they are far less in comparison to carbon dioxide in the atmosphere.  

• The tendency of carbon dioxide to remain in the atmosphere for longer durations in comparison to other heat trapping gases makes it the most potent greenhouse gas.  

Thus, the abundancy of carbon dioxide in the atmosphere makes it the most powerful greenhouse gas in comparison to other greenhouse gases.

Rats fed a standard rat diet (not organic) will be the best control group for this experiment. The correct option is A.

A control group in a scientific experiment is a group that is isolated from the rest of the laboratory activity and where the regression analysis being evaluated cannot influence the outcomes.

This isolates the independent variable's effects on the experiment and can help rule out other explanations for the experimental results.

An experimental group is made up of participants who have their independent variable manipulated in some way. These are the people who receive special treatment.

The best control group for this experiment will be rats fed a standard rat diet (not organic).

Thus, the correct option is A.

Mitosis is a cell division method a part of the cell cycle that is essential for growth and development, repair and replacement, and asexual reproduction.

Mitosis is a type of cell division method that occurs in all the somatic cells and plays a crucial role in living organisms. They produce daughter cells to increase the cell number and to aid in the growth and development.

They replace and repair the damaged cells in the body and also is a form of asexual reproduction where the parent cell is divided to form a new daughter cell with the same ploidy.

Therefore, mitosis is essential for growth, repair, and asexual reproduction.

Answer:

Have cones as reproductive structures.

Have vascular tissue.

Explanation:

The gymnosperms have vascular tissue and have cones as reproductive structures.

The gymnosperms are woody like plants having a  cone shaped structure,  bear no flowers, no fruits but bear seeds; The seeds are with out coat and they are not covered by the fruit wall.

Gymnosperms produce seeds which are not enclosed in an ovary, while in Angiosperms the reproductive organs are the flower, they may  involve in double fertilization resulting in a diploid zygote, and a triploid endosperm.

Gymnosperms  produce seeds and fruits from their flowers, the flowers in gymnosperms helped in the propagation of the plants, it attract pollinators and attracted seed to dispersers, gymnosperms became dominant among plants.

The modification of the gymnosperm includes Modified leaves, Sunken stomata, Pointed and thick cuticle leaves, Less transpiration rate.

Explanation:

Fungi reproduce asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. There are many types of asexual spores.

Answer:

hello!

Explanation:

Following a period of intensive growth, fungi enter a reproductive phase by forming and releasing vast quantities of spores. Spores are usually single cells produced by fragmentation of the mycelium or within specialized structures (sporangia, gametangia, sporophores, etc.). Spores may be produced either directly by asexual methods or indirectly by sexual reproduction. Sexual reproduction in fungi, as in other living organisms, involves the fusion of two nuclei that are brought together when two sex cells (gametes) unite. Asexual reproduction, which is simpler and more direct, may be accomplished by various methods.

Asexual reproduction

Typically in asexual reproduction, a single individual gives rise to a genetic duplicate of the progenitor without a genetic contribution from another individual. Perhaps the simplest method of reproduction of fungi is by fragmentation of the thallus, the body of a fungus. Some yeasts, which are single-celled fungi, reproduce by simple cell division, or fission, in which one cell undergoes nuclear division and splits into two daughter cells; after some growth, these cells divide, and eventually a population of cells forms. In filamentous fungi the mycelium may fragment into a number of segments, each of which is capable of growing into a new individual. In the laboratory, fungi are commonly propagated on a layer of solid nutrient agar inoculated either with spores or with fragments of mycelium.

Budding, which is another method of asexual reproduction, occurs in most yeasts and in some filamentous fungi. In this process, a bud develops on the surface of either the yeast cell or the hypha, with the cytoplasm of the bud being continuous with that of the parent cell. The nucleus of the parent cell then divides; one of the daughter nuclei migrates into the bud, and the other remains in the parent cell. The parent cell is capable of producing many buds over its surface by continuous synthesis of cytoplasm and repeated nuclear divisions. After a bud develops to a certain point and even before it is severed from the parent cell, it is itself capable of budding by the same process. In this way, a chain of cells may be produced. Eventually, the individual buds pinch off the parent cell and become individual yeast cells. Buds that are pinched off a hypha of a filamentous fungus behave as spores; that is, they germinate, each giving rise to a structure called a germ tube, which develops into a new hypha.

Although fragmentation, fission, and budding are methods of asexual reproduction in a number of fungi, the majority reproduce asexually by the formation of spores. Spores that are produced asexually are often termed mitospores, and such spores are produced in a variety of ways.

Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.

Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.

In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.
