How have human activities increased atmospheric carbon dioxide levels?

Biology
1 answer:
marissa [1.9K]3 years ago
8 0

Answer:

Human various activities like burning fossils and huge land cover changes contribute to increasing the carbon dioxide of atmosphere.

Explanation:

  • Carbon dioxide level in atmosphere is increasing naturally by organism respiration, decay, volcanoes erupt and carbonated rocks are weathered.
  • Human activities like, urbanization, deforestation, vegetation pattern changes results in changes to reflectivity of earth surface and emmision through burning fossils fuels/forest and cement production are causining an increase in atmospheric carbon di oxide level. When fossils fuel burn the carbon combine with oxygen to form CO2.
  • All these processes ultimately contribute to global warming.

Wild‑type E. coli cells can synthesize all 20 common amino acids, but some mutants, called amino acid auxotrophs, are unable to
monitta

Answer:

Complete questions include: Answer Bank: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides.

Explanation:

Glycine Auxotroph: Guanine nucleotides and adenine nucleotides (Purine nucleotides)

Glutamine auxotroph: Guanine nucleotides and adenine nucleotides (purine nucleotides)

Aspartate auxotroph: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides Both purine and pyrimidine nucleotides)

The amino acids glutamine, glycine, and aspartate provide all the nitrogen atoms of purines in a two ring-closure steps to form the purine nucleus. Pyrimidines are synthesized from carbamoyl phosphate and aspartate.

Base your answer(s) to the following question(s) on the diagram below and on
Kryger [21]

Answer:

The correct option is <em>Both Cell A&D.</em>

Explanation:

The diagram in the picture shows how a cell (A) undergoes the process of replication and produces a cell (B) containing one full set of double chromosomes.

Then, the cell undergoes the process of mitosis to produce two daughter cells (C & D).

Mitosis can be described as a method of asexual reproduction in which the daughter cells produced are identical to the parent cells and are also identical to each other. Hence, the genetic content of the cell C will be the same as the genetic content of cells A & D.

A student wants to know what effect temperature will have on the germination rate of radish seeds.  To test this, she obtains 3
kondaur [170]

Answer:

Hypothesis: IF the temperature is high, THEN the germination rate of radish seeds will increase.

Experimental Group: 20 Seeds in petri-dishes placed in the freezer and incubator each

Control Group: 20 seeds stored at room temperature

Manipulated Variable (IV): TEMPERATURE

Responding Variable (DV): GERMINATION RATE

Constants: Amount of water, same amount of time (2 weeks)

Explanation:

- The hypothesis is a testable explanation given to an observed problem. A possible hypothesis is IF the temperature is high, THEN the germination rate of radish seeds will increase.

- Independent or manipulated variable is the variable that is changed or manipulated variable in an experiment. The TEMPERATURE is the independent variable in this case.

- Dependent or responding variable is the variable that is measured in an experiment. In this case, the dependent variable is the GERMINATION RATE

- The experimental group is the group that receives the experimental treatment. In this case, the experimental group is the 20 Seeds in petri-dishes placed in the freezer and incubator each.

- The control group is the group that does not receive the experimental group. In this case, the control group is the 20 seeds stored or placed at room temperature.

- Constants are the variables that are kept unchanged throughout the experiment. In this case, the constants are Amount of water, same amount of time (2 weeks)
