Effectus [21]3 years ago
5 0

Answer:

Acid deposition represents the mix of air pollutants that deposit from the atmosphere leading to acidification of soils and freshwaters. ... Rainfall that is acidic, possesses elevated H+ ion concentrations, and has been commonly known as 'acid rain'.

Answer questions about aspects of Watson-Crick model of DNA structure
tino4ka555 [31]

Answer:

a. The directionality of the complementary strand is antiparallel. The double-stranded DNA is antiparallel comprising two strands, which run alongside each other, however, point in reverse directions. In a double-stranded molecule of DNA, the 5 prime ends of one strand align with the 3 prime ends of the other strand, and vice versa.  

b. The mediation of base pairing is done by non-covalent hydrogen bonds. It is reversible, that is, the strands can separate and can come combined again without any chemical modification.  

The specificity of base pairing is illustrated by hydrogen bonds that is, the first strand produces hydrogen bonds only with a particular base in the second strand, and these two bases produce a base-pair.  

c. The interaction or association of non-covalent type, that is, hydrophobic interaction and hydrogen bonding. Collectively, they both are strong. In the process, one base associate with the other base on the complementary strand.  

d. The phosphate backbone possesses the tendency to associate with water on the outside of the molecule, and this is favorable chemically as both the strands are held together by hydrogen bond and hydrophobic interaction.  

The polar molecules of sugar can produce hydrogen bonds with the surrounding molecules of water. The negatively charged phosphate group associate with the positively charged ions. The nonpolar nitrogen bases are found within the molecule and associate favorably through stacking interactions.

Which point in this graph shows the beginning of a period of exponential
IgorLugansk [536]

Answer:

C. Point B

Explanation:  

The exposed curve represents a logistic growth model. Population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.

Referring to population size as N, when

  • N<K, the population can still grow.
  • N approximates to K, the population´s growth speed decreases.
  • N=K the population reaches equilibrium,
  • N>K, the population must decrease in size because there are not enough resources to maintain that size.  

The sigmoid curve represents the logistic growth model.

  • Point A: During this period, the population size is relatively stable. Little growth is expressed.
  • Point B: At the beginning of this period, population growth increases softly. The more individuals are in the population, the more that reaches sexual maturity and get to reproduce, leaving fertile offspring. This fertile offspring also get to reproduce and leave more fertile individuals. At the end of the period, the curve shows a sharp slope, reflecting the significant increase in the population reproductive rate.  
  • Point C: At the beginning of this period, the population keeps on growing exponentially. But at the end of the period, the curve tends to stabilize, meaning that the population stops growing in size so fast. The population slow and gradually reaches the equilibrium point, K.
  • Point D: The population got to stabilize.
