Answer:
1: R selection
2: K selection
3: K selection
4: R selection
5: K selection.
Explanation:
K-selection species exhibit large body size, slow development, and long life span. They produce few offspring during life time and provide post natal care. The R- selection species have small body size and exhibit rapid development. They have short life span and produce large number of progeny.
Among the given options, production of large number of eggs by American green tree frog, short life span and rapid reproduction in fruit fly makes then R-selection species. Long gestation period, post natal care and production of few offspring make the rest as K selection species.
Answer:
The correct answer is D) requires phosphorylase activity.
Explanation:
Signals transmitted with the use of phosphorylation requires the presence and activity of an enzyme phosphorylase (also called Kinase) that can add phosphorus groups to proteins or other molecules in order for them to become messengers in the signaling pathway.
The question is incomplete as it does not have the tiles which has been presented in the attachment.
Explanation:
Natural selection is the mechanism by which the species evolve. The species evolve under the influence of the natural pressure due to which the species try to hit and trial method of the adaptive trait. The trait which increases the fitness of a species is passed on to the next generation and the trait becomes established in a population.
This can be observed in the following scenario
1. The hawks predate on the rabbit species with white fur easily as they can be seen from the sky easily.
2. This acts as a pressure on the white rabbits as a result of which the white rabbits to hide themselves mutate and change the colour of the fur from white to brown or tan.
3. The founder effect will eliminate the white fur population from the whole population
4. The population with brown fur will increase with time and the trait will become a permanent trait.
This rock can be classified as:
an igneous rock.
Igneous rocks are made up of
randomly arranged interlocking crystals and the important minerals that can be
found in igneous rocks are feldspars, quartz, olivines, pyroxenes, amphiboles,
and mafic minerals. All of these minerals are important in the formation of
almost all igneous rocks, and they are basic to their classification.
