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.

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.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%.

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.

Answer:
The awnser would be their DNA is made of different codon sequences.
Explanation:
The reason is Kai gets her sequences from both her mom and dad and so do her parents from their parents and on and on.
The statement that best explains the characteristics of Kai with respect to her parents is as follows:
Their DNA is made of different codon sequences.Thus, the correct option is A.
Why Kai does not appear to be identical to her parents?Kai does not appear to be identical to her parents because of the process known as variation. Variations may be defined as the process of differences in traits of individuals of a progeny from each other and from their parents.
The codon that constructs the characteristics of the DNA significantly depends on the triplet of amino acid sequences that alter the formation of proteins which governs all the properties and mechanisms of living organisms including their appearances.
Therefore, the correct option for this question is A.
