Complete Question: In apneustic breathing, which is practiced by most marine mammals:
A. A small amount of air is kept in the lungs before diving
B. A large amount of air is kept in the mouth before diving
C. Normal breathing is maintained before diving
D. Several deep breaths are taken before exhaling and diving
E. No actual breathing takes place before diving
Answer: D. Several deep breaths are taken before exhaling and diving.
Explanation:
Common dolphins, whales and other marine mammals are known to undergo apneustic breathing. This breathing process is characterized by periodic or several breathe inhalation, followed by holding their breath and then exhaling them.
Marine mammals can afterwards, went on to dive. This process prevent high water loss out. Thus, they make fewer respirations while maximizing the amount of oxygen produced for optimal consumption.

Explanation:
Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria, this curve can be used for estimating bacterial numbers by measuring absorbance for any species of bacteria.
a. True
b. False
Answer:
b. False
Explanation:
The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.
A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.
The rate of bacterial cell reproduction varies from a particular species to another.Varying species have different absorbance thresholds.
A fertilization
B prophase II
C polyploidy
D crossing over
Answer:
Hi, there your answer D. Crossing Over

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).

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

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

In a particular population, the allele frequency of the ABO blood type alleles are as follows: IA is 20%, IB is 30% and i is 50%. If mating is random and the population is in Hardy-Weinberg equilibrium, what percentage of the population will have type O blood type
Answer:
The genotypic frequency F(ii) = 0.25 = 25%
Explanation:
Due to technical problems, you will find the complete explanation in the attached files
In the blood type cases involving the ABO group, the type of inheritance here is the co-dominance type of inheritance
The percentage of the population with type O blood will be 25%
Type A (IA) is dominant to type O (i) and at the same time type B (IB) is also dominant to type O (i).Using the equation - p² + 2pq + q² + 2pr + r² + 2qr = 1Where p² indicates the genotypic frequency with type A (AA) blood and q² indicates genotypic frequency of BB and r² indicates the genotypic frequency of OO.Since we are finding the percentage with type O blood (r²) where r (allelic frequency of type O) is 0.5 (50%)
r² = 0.5² = 0.25 = 25%.

How does carbon cycle through Earth's systems? A. As fossil fuels are burned, carbon dioxide is made available for photosynthesis in animal cells. When the animals die, carbon is released into the soil, and the animal remains form new fossil fuels. B. Animals absorb carbon dioxide through their skin. Dead animals release carbon into the soil. Plants absorb the carbon from the soil and release carbon dioxide during photosynthesis. C. Plants absorb carbon dioxide through their leaves. Animals take in the carbon when they eat the plants. Animals exhale carbon dioxide. Dead plants and animals release carbon into the soilling D. Photosynthesis releases carbon dioxide into the atmosphere Cellular respiration uses carbon dioxide
Answer:
D. Photosynthesis releases carbon dioxide into the atmosphere Cellular respiration uses carbon dioxide.
Explanation:
Carbon dioxide is taken out of the air by the photosynthesis process to make carbon food for crops.
Animals and plants need a mechanism called respiration to remove carbon dioxide gas.
When combustibles are burned, carbon flows from fossil fuels to the air.

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.
