Explain How does the gradient of a river affect its flow?

Biology
1 answer:
djverab [1.8K]3 years ago
6 0

Explanation:

The flow of the river is dependent upon the position along the stream in terms of the gradient. Near the top of a high gradient, the flow will be less than that near the bottom. Likewise, the steeper the river's gradient, the faster the flow of water (due to the pull of water down the gradient by gravity).

As cytokinins are primarily produced in roots, what route would they travel to influence lateral shoot formation in a recently t
Bond [772]

The answer is symplastic transport. Transport of phytohormones such as cytokinins occurs through cytoplasm from cell to cell through plasmodesmata.  Cytokinins travel up the xylem and promote lateral growth. Gaseous molecules, such as ethylene, emitted and received by plants must pass the apoplast.

explain why it is good to sweat during/after a workout. What might happen if an athlete did not sweat?
bekas [8.4K]
Your body releases sweat to help regulate its body temperature to prevent you from overheating
Sweating also helps your body to eliminate toxins, which supports proper immune function and helps prevent diseases related to toxic overload
Sweating may help kill viruses and bacteria that cannot survive in temperatures above 98.6 degrees Fahrenheit, as well as on the surface of your skin

olchik [2.2K]

Answer:

It is expected to observe individuals exhibiting green, yellow, blue, and white colors in a phenotypic ratio of 9:3:3:1, respectively.

Explanation:

This example is a classic case of a dihybrid cross involving two unlinked genes that differ in the same observed trait. In this case, the genotype double homozygous recessive is white, while the presence of one dominant allele in one of these genes results in individuals with either blue or yellow color. Finally, the presence of two dominant alleles results in individuals with blue color.

Phenotypic and genotypic ratios:

gene 1 two alleles U u

gene 2 two alleles N n

Cross:  

UuNn x UuNn

uunn: white color (1/16)

U_nn: yellow color (3/16)

uuN_: blue color (3/16)

U_N_: green color (9/16)
