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
The stroma is the Group of answer choices space between the inner and outer membranes of a chloroplast. watery fluid enclosed by the inner membrane of a mitochondrion. thick fluid enclosed by the inner chloroplast membrane. space between the inner and outer membranes of a mitochondrion.
Answer: The correct option to the question is (thick fluid enclosed by the inner chloroplast membrane).
Explanation:
Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle. In electron micrographs, thylakoid membranes look like stacks of coins, although the compartments they form are connected like a maze of chambers. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the STROMA
The STROMA is made up of thick colourless fluid which surrounds the thylakoid and is enclosed within the inner chloroplast membrane. The stroma is essential for photosynthesis because:
--> it contains the enzymes necessary for carbon fixation,
--> it also manages the chloroplast response to cellular stresses and signaling between various organelles.
--> It plays an important role in both the light-dependent and light-independent reactions of photosynthesis.

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
Explanation:
When determining CFU/mL, plates with more than 300 colonies should be eliminated from analysis, being designated: Group of answer choices TNTC TSA TVAC TFTC
Answer:
TNTC
Explanation:
The correct option would be TNTC.
TNTC simply means Too Numerous To Count. The term is usually reserved for bacterial culture plates with high bacterial loads, usually in the excess of 300 colonies. It is as opposed to TFTC (Too Few To Count) which is the term used when the colony count on a bacterial culture plate is less than 30.
When a bacterial culture plate is too numerous to count, it can either be eliminated from data analysis or the sample diluted to lower the bacterial load.

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).
