Answer:
1. Terrestrial ecosystem, 2. Aquatic ecosystem.
Explanation:
A terrestrial ecosystem is an ecosystem that exists on land. An aquatic ecosystem id an ecosystem that exists within a niche.
Answer:
Weight and skin color.
You can be born with a different skin color and it can change according to the place you live in. Suppose you were born in Alaska and moved to Mexico, your skin color would become darker as you will receive more vitamin D. You body structure to will also be based on your parents. If your parents are fat but you exercise and eat healthy your body structure will change.
Answer:
b) Systematics
Explanation:
Darwin presented the theory of evolution and explained that the process of evolution occured because of natural selection which further explains that offsprings are produced from organisms and these organisms are able to survive in their environment.
As systematics is the branch of biology, which basically deals with evolutionary relationships of the organisms .Thus the darwin theory of evolution will be considered in the field of systematics.
Hence the option B) Systematics is the right option.
I'd say A. Because the only data we have is that at a 5.4 pH level, flies are not welcome.
Hope it helped!
Answer:
The statement supported by the description of the process of protein synthesis determined by DNA and its packaging and sorted by the Golgi apparatus is that various organelles within a cell interact with each other to carry out life processes (option D).
Explanation:
From the transcription of RNA from DNA to protein synthesis and its packaging and distribution, the participation of organelles is observed:
- <em>Cell nucleus</em><em>: contains the DNA and is where the transcription into mRNA occurs.
</em>
- <em>Ribosomes</em><em>: where the mRNA is coupled to produce translation and protein synthesis.
</em>
- <em>Rough endoplasmic reticulum</em><em>: contains ribosomes and participates in the process of membrane protein synthesis, also contributing to their conjugation, glycosylation or sulfonation.
</em>
- <em>Golgi apparatus</em><em>: it is in charge of receiving synthesized proteins, packaging and distributing them to be sent to the extracellular space or other cells.
</em>
In this way, the coordination of the functions of various organelles is useful and necessary to fulfill vital functions. The statement that varoius organelles within the cell interact with each other to carry out life processes is, therefore, correct.
<em>The options for this question are:</em>
<em> A. Organelles within a cell act independently of each other at all times
</em>
<em> B. Some organelles are more important than other organelles within a cell.
</em>
<em> C. Only up to three organelles may interact with each other at any given moment in time.
</em>
<em> D. </em><u><em>Various organelles within a cell interact with each other to carry out life processes.</em></u>
