Hey there Amber!
Question #1
<span>Which of the following is NOT a characteristic of all life?
</span>
Your correct answer would be the "ability to move". Not all thing's in life can move. Just think of some other living thing's that does not have this.
Question #2
<span>Which of the following is the function of the Endoplasmic Reticulum?
</span>
Based on my information, the function of this would be of that it produces proteins
Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
Answer:
A
Explanation:
Succession is natural process resulting in the existence of a new species from a parent species, differing in some characterisrics native to the parents (mostly enhanced differences). It often defines a natural selective process, in that such enhancements of characteristics maybe elude some members(geni) of the species in question or distributed randomly among the species.
Answer:
Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.
Explanation:
Since the four proteins used p16, p18, p21, and p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.
Hope that answers the question, have a great day!
A reflex is a built in operation that performs without orders from your mind.
A habit is something you as a person forms and we can train our minds to stop the habit.
