1. How is pressure related to force and surface area?

1 answer:

4 0

Air pressure pushes all around you, it is the force of air spread over the surface area of your skin

pressure is the measure of how much force over a certain area

this is an example
imagine putting a 10 pound weight (disk) on your stomach (not dropping, puttting), not too hard right, now imagine that it was 1 pin that was 10 pounds, that would hurt, the force is still 10 pounds down but the surface area is alot smaller, more pressure

there are multiple chickens and rabbits in a cage there are 72 heads and 200 feet inside of the cage how many chickens are in th

schepotkina [342]

The answer is 44 chickens and 28 rabbits.

We have a system of two equations.
x - the number of rabbits
y - the number of chickens

Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.

Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.

Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.

A cell under a microscope shows Two daughter cells were formed and they are haploid. Which stage of meiosis is the cell showing?

Nadya [2.5K]

The answer is <span>Meiosis I.</span>

<span>Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.</span>

<span>Therefore, the production of two haploid daughter cells is in meiosis I.</span>

In humans, the allele for dimples (D) is dominant to the allele for no dimples (d). At another gene locus, the allele for broad

Inga [223]

Answer:

Explanation:

As given, Allele for dimples(D) is dominant over alleles for no dimples (d), so D is dominant over d.

Allele for broad eyebrows (B) is dominant over allele for slender eyebrows (b), so B is dominant over b.

A man heterozygous for both traits ( DdBb) marries a women who has no dimple and heterozygous fro eyebrow (ddBb)

So cross is = DdBb × ddBb

1). Genotype of the man is DdBb.

2). Genotype of the woman is ddBb.

3). Genotype of the gametes produced by the man are DB, Db, dB and db.

4). Genotype of the gametes produced by the woman are dB and db.

5). Probability that their first child will have dimples 50% or 1/2

6). Probability that there first child will have both dimples as well as slender eyebrows 1/8

Mark is studying jellyfish in a small body of water. Mollusks are a primary food source for jellyfish, and a large number of mol

ankoles [38]

Answer:

Carrying capacity for the jellyfish would reduce

Explanation:

Carrying capacity of a biological population in an ecosystem is the maximum number of population size the environment or habitat can conveniently cater for given the available resources such as, food, water supply, space etc.

The survival of the jelly fish largely in the small body of water would be largely dependent on how much food that is available.

The large number of mollusks harvested would reduce the available food in the small body of water, hence, reducing the carrying capacity for jellyfish.
