Answer: The correct answer is-  50 percent Tt, 50 percent tt.

In pea plants tallness ( depicted by T allele) is a dominant trait over shortness ( depicted by t allele), which is a recessive trait. The possible genotypes of tall are Tt and TT whereas for short plant is tt.

As per the question, genotype of parents is - tt ( homozygpus short) and Tt ( heterozygous tall).

The gametes produced by tt are 't' and 't' whereas by Tt are 'T' and 't'.

When these parents are crossed, they will produce 50 percent Tt, 50 percent tt offsprings.

How might a single hormone have drastically different effects in
OlgaM077 [116]

Answer:

The correct answer is "There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include: multiple receptors for the same hormone, a single receptor coupled to different pathways and hormones interacting with receptors for other molecules".

Explanation:

Hormones are among the most versatile molecules of the body, responsible for different biological processes such as human growth, sex development and metabolisms. Hormones are responsible of these complex biological processes because they have drastically different effects in different cells. There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include:

- Multiple receptors for the same hormone. For instance, there are multiple receptor for dopamine, a hormone and neurotransmitter responsible for different functions such as movement, memory, sleep and motivation.

- A single receptor coupled to different pathways. Most hormone receptors act with a cascade of signaling. This in consequence results in a single receptor interacting with different molecules having multiple effects.

- Hormones interacting with receptors for other molecules. One example is the action of one metabolite of progesterone named allopregnanolone. This metabolite interacts with GABA-A receptor, which gives it anxiolitic properties.

List the 8 elements of weather that are observed for making weather forecasts
NemiM [27]
Temperature, precipitation, wind direction, wind speed, clouds (types and altitudes), atmospheric pressure, humidity, and visibility. It really depends on what you're forecasting but most of the time forecasters look for high/low-pressure systems in weather models and behavior of various winds at levels such as jet stream.

podryga [215]
A. RNA is single-stranded and DNA is always double-stranded
this is the correct answer, hope this helps. it cant be B because RNA mutates before forming DNA, and protein helps with protein synthesis, so not D
