Answer:

According to what is observed in point A of the graph, referring to the population of beetles, there is no competition for resources.

Explanation:

The graph shows that a controlled population of beetles, where other individuals do not enter or leave, experiences progressive growth over time. This is because the population has sufficient resources to guarantee their development, the birth rate exceeds that of mortality and there is no competition for these resources.

The adequate amount of resources allows that, at point A, the carrying capacity has not been reached, a consequence of no competition among members of the same species, which ensures that the net population growth rate is maintained or even increase.

Increasing temperatures in the atmosphere have caused the temperature of the oceans to _______, leading to more powerful tropica

Serjik [45]

Answer No 1)

Increasing temperatures in the atmosphere have caused the temperature of the oceans to increase leading to more powerful tropical storms.

Approximately 25 percent of carbon dioxide emitted into the atmosphere is absorbed in the oceans.

Waste water treatment is critical to removing pollutants from contaminated water by using physical, chemical, or biological processes.

Water pollution can come from the decomposition of dead organic matter or animal waste in waterways.

Water pollution increases the salinity and slows down major ocean currents that are responsible for regulating Earth's climate.

Explanation:

The devastating effects of global warming effects both the land and the aquatic biomes.

The excess carbon dioxide produced as a result of global warming is absorbed by the oceans. This imposes a serious threat on the biodiversity of the aquatic life. The dead organism also produce pollution when they degrade in the oceans.

It is essential that before ocean water is used for any kind of consumption, the water be effectively treated to remove all kinds of toxicity from it.

Answer 2)

Water quality can be improved through conservation by :

a) using less amount of water for house-hold purposes: In our daily lives, humans use extra amounts of water fro house- hold activities such as while washing clothes or washing dishes. It should be ensured that we use a reasonable amount of water for every house-hold activity.

b) Fix the leakages: Majority of the houses in a society will not be concerned about a minor water leakage from taps, pipes etc. But it is essential to conserve every drop of water and these leakages need to be fixed. The more water we conserve, the more improved quality water will be available.

An RNA sequence includes 12 nitrogenous bases, AUGGUGCAUGUC. What is the maximum number of amino acids for which this sequence c

GREYUIT [131]

Answer:

In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).

Explanation:

Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.

From the sequence:

AUGGUGCAUGUC

Four codons are obtained, each of which encodes a different amino acid:

Codons: AUG-GUG-CAU-GUC

Amino acids: Met - Val - His - Val

Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.

Are plant cells and animal cells exactly the Same? Explain and give examples.

ale4655 [162]

Answer:

Explanation:

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. ... Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
