After three years of heavy rain, a field of soybeans shows a decreased yield. They have weaker root systems compared to plants i
Troyanec [42]

Answer:

It can be hypothesized that fungal pathogen is responsible for decreased yield.

Explanation:

As the extensive heavy rain changed the climate of that area the soybean plant was effected by pathogenic fungus grown in the field. As we know that fungi makes spores that can withstand harsh environment. Humid and moist environment is favorable for fungi growth. So when spores find a suitable environment they grow rapidly. In the given example, the fungi was pathogenic that produced toxic compounds and effected the growth of soybean plant by damaging its root system and water supply to plant.

What results when a single bacterium reproduces?
tiny-mole [99]

Answer:

<h2>b. Two genetically identical daughter cells.</h2>

Explanation:

Bacterial reproduction:

Mainly,bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two  genetically identical daughter cells. Binary fission begins when the DNA of the bacterium first replicate and becomes double ,then the rest cell organelles also duplicate in the bacterium cell, finally the bacteria divides into two genetically identical daughter cells. Both cell are similar in size, shape and genetic composition.

How and why does the epidermis produce new skin cells?
ArbitrLikvidat [17]

Answer:

About 95 percent of the skin cells in the epidermis are devoted to creating new skin cells in the lower two levels of the epidermis, which then cycle to the top layer to help form the stratum corneum. Eventually the dead cells of the stratum corneum flake off as new keratinocytes move up, and the cycle repeats itself.

Hope this answer is right!!

PLEASE I NEED THIS ASAP If you had a cell that was cube-shaped with a side length of 20µm, calculate the surface to volume ratio
weeeeeb [17]

Answer:

Ratio = 3\times 10^5

Explanation:

Side of a cube, a = 20 µm

a=20\times 10^{-6}\ m

The surface area of a cube, A = 6a² (a is side of the cube)

The volume of a cube, V = a³

The ratio of the surface to volume ratio of the cell will be given by :

R=\dfrac{6a^2}{a^3}\\\\R=\dfrac{6}{a}\\\\R=\dfrac{6}{20\times 10^{-6}}\\\\R=3\times 10^5

So, the ratio of the surface to volume ratio of the cell 3\times 10^5.
