Answer:
The given blank can be filed with stasis.
Explanation:
There are various kinds of species that have been discovered in the world and had remained unmodified, that is, right from the start. This has been supported by their fossil records that in the geological strata they were witnessed unchanged. This phenomenon is termed as stasis, in which the species do not exhibit any kind of directional change. The starfish, lungfish, and the tribolates belong to this category, that is, their current time appearance is identical to the fossil records.
The metric system is based on 10.
I would say the answer is A. Seafloor is spreading. Arrows in the map show the tectonic plates moving away from each other.
I hope this helps!
1. A plant cell has chloroplasts
2. A plant cell has a cell wall
3. A plant cell has vacuoles
An animal cell has none of these features.
Answer:
Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.
Explanation:
Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.
- Performing the experiment on yeast would give good results for singular-celled organisms, like <em>protozoa</em>.
- Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like <em>spiders</em>.
- Performing the experiment on zebrafish would give good results for all fish in general.
