Which point in this graph shows the beginning of a period of exponential

Biology

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.

3. How is carbon added to the atmosphere?
vova2212 [387]

Answer:

Explanation:

Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement

The information from messenger RNA is used to create polypeptide sequences during what process?
sergiy2304 [10]
<h2>Answer</h2>

The translation process activates to create polypeptide sequences.

<h2>Explanation</h2>

When the messenger RNA gets information (codon) from the DNA, it comes toward the ribosomes where transfer RNA also attached. At the ribosomes, the transfer RNA decodes the information of messenger RNA as match its anticodons with codons of messenger RNA. (Nucleotides as A with U and C with G). This process of decoding at the ribosomes with the help of transfer RNA called the translation process which ultimately leads the process toward releasing of long chain peptide.

Which of the following is the most likely flow of energy in an aquatic ecosystem? a. Phytoplankton → mammal → zooplankton → fish
VladimirAG [237]

In this question, the correct order of flow of energy in an aquatic ecosystem is Phytoplankton → zooplankton → fish → mammal.

<h3>What do you mean by an Ecosystem?</h3>

An environment may be defined as the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival.

The flow of energy in an aquatic ecosystem depends on the phytoplankton which are known as the producers of an aquatic ecosystem.

Therefore, the correct order of flow of energy in an aquatic ecosystem is described above. Hence, the correct option is B.
