4 0

Answer:

level 2 = 3,000  level 3=300

Explanation:

Only 10 percent will be transferred to the next level and 10 percent of 30,000 is 3,000. 10 percent of 3000 is 300

How water quality changes from source of a river to the mouth
irina [24]

Answer:

use own words!!!

Explanation: Velocity increases as more water is added to rivers via tributary rivers. This means that less of the water is in contact with the bed of the river and the mouth so there is less energy used to overcome friction. Hence rivers flow progressively faster on their journey downstream.

In a large flock of 6520 sheep, 53 of them have yellow fat while the rest of the flock members have white fat. Yellow fat is inh
Natasha_Volkova [10]

Answer:

number of sheep with homozygous dominant white fat genotype = 5399

Explanation:

If p = frequency of dominant allele and q= frequency of recessive allele

According to Hardy-Weinberg equilibrium:

p + q =1 and p² + 2pq + q² = 1

where p² = frequency of homozygous dominant genotype

q²= frequency of homozygous recessive genotype

and 2pq= frequency of heterozygous genotype

Here,

q² = 53/6520= 0.0081

q = √0.0081 = 0.09

p = 1-q = 1-0.09= 0.91

So, p² = 0.91² = 0.8281

number of sheep with homozygous dominant white fat genotype= 0.8281*6520 = 5399

PLEASE HELP!! WILL GIVE BRAINLIEST TO WHO ANSWERS FIRST!!!!

Example 1:

Endoplasmic reticulum (ER) are like factories of cells. If we consider cell as a international clothing chain of companies, then ER are the ones which plan and design the clothing, sew those up, put additional buttons etc. on them, and then ship them on time. The workers (manual and automatic) do the whole procedure.

To understand it better in terms of cellular functions, ER create biomolecules essential for cells and the body as a whole. ribosomes are the workers which do the synthesis. With the help of ribosomes, ER makes the whole process of biomolecule synthesis, modification and delivery smooth, efficient and accurate.

Example 2:

Think of ER as Uber Eats. It provides you the catalogue of delicious food available and can be sent, then forwards your request to the restaurant, then sends a delivery person to wait and collect the order, and then orders the person to delivery food to the correct address on time.

Here, ribosomes would be the restaurants making the food.

**This is a simplification of the actual function of ER but I hope you get the gist. While talking about smooth and rough ER, the examples may change.

Which statement best describes the phases of the Moon?
Deffense [45]

Answer:

During the waning phase of the Moon, less of the Moon's near side is lít each night

Phases of the moon are different ways the moon appear on the Earth. As moon orbit the Earth, half of the moon that faces the Earth will be lit up. There are different phases of moon which are full moon, quarter moon, waning crescent moon, waning gibbous moon, e.t.c.

A waxing crescent moon is when the moon look like crescent and it increases in size.

A waning gibbous moon occurs when more than half of the lit portion of the Moon can be seen and the shape reduce in size . It occur between the full and quarter moon.
