Answer:
C. four single covalent bonds
Explanation:
Carbon atoms can form four single covalent bonds.
Answer:
Changes occurs in the environmental conditions directly affect carrying capacity of the ecosystem.
Explanation:
Carrying capacity of the ecosystem refers to the capacity of the environment which adjust plants and animals in a specific atmospheric condition. Suppose in harsh winter, the temperature of the ecosystem is very low which is unbearable for most of the plant and animal species, so very low number of plants and animals are able to live in that environment. In the ecosystem where the winter is harsh and the spring is cold, the population of living organism are more decreasing. If the ecosystem has Harsh winter, Cold spring, and Hot summer, this type of environment hold very low number of living species due to high variation in the environment.
Because it’s wet and has a low PH so it’s a coolant
Answer:
The correct order of the steps of light dependent reaction is described below
Explanation:
Step 1 light energy is absorbed and transferred to the reaction center
Step 2 water molecule is splited
Step 3 Electrons are transferred from photosystem 2 to photosystem 1
Step 4 ATP is synthesized from ADP and inorganic phosphate.
Answer:
Parentals: PP (purple) and pp (white)
F1: Pp (purple)
Explanation:
When the two parental plants of differing phenotypes (purple or white flowers) cross, the F1 is 100% purple. This result suggests that the parentals were true breeding (homozygous), with purple flowers being the dominant allele.
When the F1 self pollinates, the F2 shows proportions very similar to 3/4 purple and 1/4 white (401/532 ≅ 3/4 and 131/532 ≅ 1/4). The 3:1 phenotypic ratio is typical of the offspring resulting from a cross between two heterozygous individuals.
The results make sense if the genotypes of the different generations are:
Parentals: PP (purple) X pp (white)
F1: Pp (purple)
F2: 1/4 PP, 2/4 Pp, 1/4 pp
