About 70% of the human population can taste the bitter chemical phenylthiocarbamide (PTC), which is found in foods like broccoli

. The allele, T, for tasting PTC is dominant over the allele, t, for not tasting it. Calculate the allele frequencies using the Hardy-Weinberg equation, where p represents the dominant allele frequency, and represents the recessive allele frequency. Which of the following is closest to your results?
A. p = 0.45; q = 0.55
B. p = 0.84;q0.55
C. p = 0.70;q=0.30
D. p = 0.84; q = 0.16

Which organelle carries substances to other parts of the cell?
STALIN [3.7K]
The answer will be Endoplasmic Reticulum (ER).

It is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.

Well, to make it easier, endoplasmic reticulum is actually a fancy way of saying "cellular highway". I will explain to you why. I always like to study BIOLOGY relating our activities and our stuff. 

Okay, let's push aside cells. Let's think of us, humans. We can't stay in one place, we gotta moving all around the city. What do we use for moving around the city: either roads or sidewalks or footpaths.

Just like that, a cell also has a medium or road or a channel where all the substances can move around the cell. Well, its ER! So, from now on, everytime you are struggling with this difficult, L O N G word, just replace it with "cellular highway". The ER is like a water pipe, too. Water flows through it. Here, cellur substances flow through it. The ER is connected to the nucleus.

SUMMARY:

1# ER aka Endoplasmic Reticulum is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.

2# 
Try thinking it easy: replace it with "cellular highway".

3# 
It is much like the roads or sidewalks, we walk on.

Polysaccharide structure can be varied by differences in ________.
Scilla [17]

Answer:

monomers of MONOSACCHARIDES

Explanation:

Polysaccharides are large molecules formed from chains of POLYMERS linked together by glyosidic bonds. <u>MONOMERS are small sub units that formed polymers, they are therefore the building block of a polysaccharides.  The monomers of polysaccharides are called monosaccharid</u>es (1 sugar molecule.) when two of these are joined together they formed disaccharides (two sugars.)

Polysaccharides are fromed by joining  together condensation, (loss of water molecules,)  of mutiple monosaccharides units and the reversal of this to add water molecules to sepate them to monosaccharies is  sugar Hydrolysis.

Example of polysaccharides are starch, glycogen cellulose

Example of monosaccharides are glucose, galactose.

Disaccharides are common table sugar, sucrose, maltose, lactose

Carbohydrates must be consumed every 3 to 4 hours to prevent depletion of the glucose in our blood.
Varvara68 [4.7K]

Answer: option B) False

Explanation:

The body relies on SEVERAL sources for its energy or glucose supply.

Firstly, understand that Glucose could be supplied from the following:

Glycogenolysis (Glycogen break down induced by Glucagon)

Amino acids metabolism (once amine group is removed)

Fatty acid oxidation.

All of the pathways mentioned can directly or indirectly yeild GLUCOSE, thus making it UNNECESSARY for Carbohydrate meals to be consumed every 3 to 4 hours.

Therefore, the answer is False
