Many poisonous mushrooms are extremely colorful. One hypothesis is that the colors serve as a warning to prevent animals from ea

ting the mushrooms, much like the bright yellow and black stripes on wasps help to deter potential predators. Why do mushrooms need to deter predators when the majority of a mushroom consists of the underground mycelium?

Answer:

Many poisonous mushrooms have bright colors that serve as the warning signal to animals that the mushroom is poisonous and by eating it they can die.  

Mushroom is a fungus and most of its part is consists of underground mycelium. The part of the mushroom which is above the ground is the fruiting body of mushroom and is umbrella-like. It is called cap in which gills underside of the cap. These gills contain spores that are disperse and produce more mushrooms.

Therefore as the cap is fruiting body and contains spore so to protect the spores mushroom need to deter predators.

Answer: To protect the spores that is inside the upper part of the mushroom.

Explanation:

Many poisonous mushrooms appear in bright colors and they serve as the indicator of the poison in it.

This is done in spite the mycelium part of the mushroom is underground because the upper part of the mushroom is responsible for carrying spores.

These spores disperse with wind which is responsible for the growth of new mushrooms so the upper part of the mushroom is equally important as like that of lower one.

So it needs to be colorful so that the predators do not eat them.

Y-: yellow S-: star yy: black ss: starless
Ede4ka [16]

Answer:

1. heterozygous yellow and star

2. 37

3. 1/8

4. 168

5. 1/4

Explanation:

Given ,

In f1 generation a cross is made between a true breeding black star bellied sneetch mated with a true breeding yellow starless sneetch

yySS x YYss

It is taken as - Y (yellow) is dominant over y (black)

and S (star) is dominant over s (starless)

1. F1 Generation

Genotype of parents yySS X YYss

gametes - yS, yS, Ys, Ys

All 16 offspring will have genotype YySs

phenotype would be heterozygous yellow and star

2. F2 generation cross

YySs X YySs

YS        Ys         yS        ys

YS YYSS YYSs YySS YySy

Ys YYSs YYss YySs Yyss

yS YySS YySs yySS yySs

ys YySs Yyss yySs yyss

Genotype of offspring are –  

YYSS – 1

YYSs – 2

YySS – 2

YySs – 4

YYss- 1

Yyss- 2

yySS – 1

yySs- 1

yyss- 1

2. Out of 16, 2 are black star bellied sneetches . Which means only 1/8 are black star bellied sneetches

So out of 300, 37 are black star bellied sneetches

3. Only 2 out of 16 are true breeding. i.e 1/8

4. 9 out of 16 are yellow star bellied sneetches, so out of 300, 168 are yellow star bellied sneetches

5. 4 out of 16 are true breeding yellow. Thus, ¼ are true breeding

2. As a result of your initial efforts you were able to detect the presence of protein K using IgG. However, when your lab mate
Viefleur [7K]

Answer:

Protein K is a protein that can available in the human cell nucleus that binds to pre-messenger RNA as a part of heterogenous ribonucleoprotein. IgG is one of the five isotypes of immunoglobulin or antibodies.it is the most common antibodies in the blood circulation and makes the 75% of total antibody.

When you heat solution, generally protein k activity increase with an increase in the heat but up to an extent or point called optimum temp. The optimal temperature for activity ranges between 50-65°c. When an increase in temperature help with protein unfolding easing the ability for protein k to break down those proteins.

Bacterial flagella have which functions? check all that apply
marishachu [46]
<span>Option A and B. They are the organelle of locomotion for most bacteria capable of motility. And, a motile response to an environmental stimulus. Bacterial flagella are helical filaments made up of the protein flagellin 20-nanometer-thick with a rotary motor at its base which can turn clockwise or counterclockwise. Like the multicellular flagellum the primary role of the flagellum is locomotion, bacterial mobility, but it often functions as a sensory organelle in response to external stimuli like exposure to chemicals and temperatures outside the cell.</span>
