Answer: ima say its true
Explanation: Several substances serve as buffers in the body, including cell and plasma proteins, hemoglobin, phosphates, bicarbonate ions, and carbonic acid. ... The respiratory and renal systems also play major roles in acid-base homeostasis by removing CO2 and hydrogen ions, respectively, from the body.
I think the answer is B
Hope this helps!!!:)
Have a good day!
Answer:
The photosynthesis chemical reaction looks like this:
6 CO₂ + 6 H₂O --> C₆H₁₂O₆ + 6 O₂
The cellular respiration chemical reaction looks like this:
C₆H₁₂O₆ + 6 O₂ --> 6 CO₂ + 6 H₂O
As you can see, the processes involve the same substances. However, the reactants and the products are switched. The reactants for photosynthesis are the products for cellular respiration, and vice versa. For example, the products of photosynthesis are glucose (C₆H₁₂O₆) and oxygen. On the other hand, these are the reactants necessary for cellular respiration.
Answer:
1. How did the tidal wave affect the predicted frequencies of the alleles in the population?
No changes
2. What is the frequency of the recessive allele?
q= 0.6
Explanation:
If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.
If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:
q^2 = 36/100
q= √36/100= 6/10= 0.6
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.
