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

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

Excessive nutrients from fertilizer in runoff often cause excessive growth of which can lead to the creation of dead zones in aquatic ecosystems.
Answer:
Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Nutrients can run off of land in urban areas where lawn and garden fertilizers are used
Explanation:
Excessive nutrients from fertilizer in runoff often cause excessive growth of which can lead to the creation of dead zones in aquatic ecosystems is known as eutrophication.
This nutrient overload give rise to dense growth of algae, water hyacinth. and Cyanobacteria. When the algae die out, their decomposition by aerobic bacteria (oxygen presence) depletes dissolved oxygen in the surface layer of water near the shore and in the bottom layer.
What is biochemical oxygen demand (BOD)?
The biochemical oxygen demand (BOD) is defined as the amount of dissolved oxygen consumed by biological organisms when they decompose organic matter in water.
This oxygen depletion may kill fish and other aquatic animals. If excess nutrients continue to enters into lake, then anaerobic bacteria take over and produce gaseous decomposition products such as smelly, highly toxic hydrogen sulfide and other flammable methane gases.
