Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
A. a caliper and a flask
B. a stopwatch and a beaker
C. a balance and a beaker
D. a meter stick and a temperature probe
Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.

Q6. In mice, the allele for black hair color is (B) dominant to that for brown (b), the allele for
short hair (H) is dominant to that for long hair (h). The gene for hair color and length are not
linked (i.e. they are on separate chromosomes).
One colony (colony A) of mice was pure breeding for short hair; a second colony (colony B) was
pure breeding for long brown hair.
a. A male from colony A was mated with a female in colony B.
i.
Give the genotype of the male from colony A and the genotype of female in
colony B. (2mks)
ii.
These two mice were crossed and produce a large number of offspring (F1).
Construct punnet squares to show this result (3mks)
iii.
Give the genotypes and phenotypes (ratio) of this F1 generation (2mks)
Genotypes:
Phenotypes:
Answer:
The correct answer is -
A (i) a male from colony A HH and female from colony B bbhh
(ii) the offspring will be heterozygous for short brown hair
(iii) genotype 100% Hhb, phenotype - 100% short brown hair
Explanation:
It is given that parent one is from Colony A that is pure breeding for short hair which means p1 is HH and parent 2 is from colony B that is pure breeding for long brown hair that means p2 is bbhh.
Cross between HH and bbhh
Gemetes : H, H, and bh, bh,
Punnet:
bh bh
H Hhb Hhb
H HhB Hhb
Thus, the offspring will be heterozygous for short brown hair

Answer:
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.
Dynamic term describes the plasma membrane. So, the correct option is (B).
What is Plasma membrane?Plasma membrane also known as cell membrane is a membrane found in all cells that separates the interior of the cell from the external environment. The plasma membrane consists of a lipid bilayer that is semi-permeable that regulates the transport of materials entering and exiting the cell.
This membrane is called a selectively permeable membrane because it controls the movement of substances in and out of the cell, which means that the plasma membrane allows certain materials to pass through it, while at the same time it prevents other materials from entering through it. Plasma membrane is dynamic in nature.
Thus, Dynamic term describes the plasma membrane. So, the correct option is (B).

How can you drop two eggs the fewest amount of times, without them breaking?
Answer:
yes yes i have seen this before,let me guess its from go.ogle
from calculating how thick and strong the shell is i prefer using a egg with a born baby inside becasue it takes energy from divideing cells thus making it lighter and less likly to break and they can stand a weight of 130 pound weight without breaking thus 6 inches to 8 inches will be the answer
i prefer ostrich eggs and make sure to get younger birds they have harder eggs
thus you can keep doing it and 3 out of 10 egg shall break this is real math so ya
