Answer:
This question lacks options, the options are:
a) Negative primary production
b) Net primary production
c) Secondary production
d) Negative secondary production
e) Positive primary production
The correct answer is b.
The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production. The energy that remains after plants use some of the gross primary production to fuel their own metabolism is known as <u>net primary production</u>.
Explanation:
Net Primary Production (NPP) is the value that results from the difference between gross production and respiration of the primary producers themselves. It manifests as growth and / or reproduction. It represents the matter and energy available for the next trophic level, that is, the net primary production is what is left after subtracting the energy that plants use for their metabolism or maintenance (such as breathing, tissue construction and reproduction).
Answer:
C
Explanation:
Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.
In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).
We have the Gregor Mendel's cross as in the image attached here.
All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.
The answer is c (the offspring plants have a genotype that was different from that of both parents).
NUCLEAR FUSION, hope it helps
The genotype of the plant is <span>WwXxYyZz.
The plant has a 50% chance of passing each of the alleles of a gene, the dominant or the recessive.
So, for producing the haploid genotype of a gamete </span><span>Wxyz the chance is
0,5 (W)* 0,5 (x)* 0,5 (y) * 0,5( z)= 0,0625
