What is a likely consequence of continued human population growth? A. More cropland B. Less erosion C. Less pollution D. More ra
omeli [17]

Answer:

The correct answer is option A More cropland

Explanation:

As the human population will increase, their demand for resources will also increase specifically for the three essentials namely  air, water and food. In order to cater the need of increased food demand, more food is needed to be produced and thus more land is required. Apart from agricultural produce, even dairy farms, aquaculture or any other  method of production of non vegetarian/other food sources,  also require large amount of pasture land or crop land.

Gene X always produces the same mRNA (one splice form) and the same protein in all cells in which it is expressed. The same amou
AysviL [449]

There are two explanations for this phenomenon: phosphorylation of the protein X in the heart activates its function (Option C) or phosphorylation of the protein X in the kidney and the brain deactivates its function (Option D). Therefore, both Option C and Option D are correct.

  • Phosphorylation is a posttranslational protein modification that is capable of activating or deactivating protein function.

  • Phosphorylation alters the three-dimensional structure of a protein, thereby modifying its function (i.e., activate or deactivate the target protein).

  • Phosphorylation occurs at specific amino acids (e.g., serine and threonine residues) of the target protein.

  • Moreover, mRNA splicing (RNA processing) occurs before the protein state, it is a transcriptional process. This process consists in removing the non-coding regions or 'introns' from pre-mRNA and subsequent joining protein-coding regions or 'exons' to enable the translation of the mRNA into a protein.

  • In consequence, in this case, it is possible that 1-phosphorylation of the protein X in the heart activates its function, or 2-phosphorylation of the protein X in the kidney and the brain deactivates its function. Therefore, both Option C and Option D are correct.

1. What is an invasive species?
NARA [144]
1. Am invasive species is not apart/native to a specific area and could potentially cause damage to the environment and in some cases human health.
2.Invasive species can be found anywhere, considering that they are not native to an area.
3. Many invasive species form interactions with pollinators, DIRECTLY, and even though this isn’t necessary to the invader, pollinators are the direct role because they play a part in plant invasion, basically meaning they could damage the plant greatly. More direct consequences could be competition.
4. An example of INDIRECT consequences would be via a multi species. Like for example, effecting a certain species just to get to another species, diversely.
5. There are many ways that an invasive species could be introduced mostly by people however.


Part a- A vector is a specific organism that by itself couldn’t spread a certain disease, but by pathogens
Part b- A pathways is different from a vector however because it is along with molecules. These molecules could lead to change in a cell or potentially damage.


Hope this helps! :)
