The true statements are:
Only a fraction of matter consumed at lower trophic levels is transferred to higher trophic levels to produce growth and release energy through cellular respiration.
And
There are fewer organisms at the higher trophic levels of a food web.
These first statement is actually the reason for the second.
Explanation:
Unclear question. However, I infer you need rendering of the question which reads;
"In a cross between homozygous pea plants with round yellow seeds (AABB) and homozygous pea plants with wrinkled green seeds (aabb), what is the probability that an F2 plant has yellow round seeds?
A) The probability is 12:16 or 75%.
B) The probability is 8:16 or 50%.
C) The probability is 4:16 or 25%.
D) cannot be determined
Answer:
Explanation
Given that 36% are recessive in traits
100-36 = 64% for dominant traits considering a whole population to be 100%
P=dominant allele
q= recessive allele
P2= dominant genotype
q2= recessive genotype
according to hardyweinberg principle, p+q=1
64/100= 0.64 frequency for dominant traits or genotype, therefore
p2=0.64
then
P=√0.64
p= 0.8
Therefore, dominant allele frequency (p) for the population is 0.8
Answer:Photosynthesis is the process by which plants use the energy of sunlight to make sugar (glucose) from carbon dioxide and water. Respiration is the process by which animals use O2 to get energy from food. So plants take in CO2 from the air and produce O2, and animals take in O2 from the air and produce CO2.
Explanation:
False, there are lots of biomes on earth.
