The palisade cells are the main site of photosynthesis, as they have many more chloroplasts than spongy mesophyll, and also have several adaptations to maximizes photosynthesis efficiency. Large Vacuole restricts chloroplasts to a later near outside of the cell where they can be reached by light more easily.
Answer:
1. genetic drift; 2. natural selection; 3. gene flow; 4. natural selection
Explanation:
<u>1. A fish net captures twenty fish, all who happened to have large spots:
</u>
The mechanism of evolution that is playing out in this situation is most likely <u>genetic drift.</u> Genetic drift occurs when a random change occurs, resulting in the selection of a number of individuals by chance, rather than based on their level of fitness. The fish with large spots allele were selected against by chance, not necessarily because the fish with the small spot alleles were better fitted.
<u>2. Small spotted fish escape from predators better:</u>
The situation here is <u>natural selection</u>. The small spotted fish possess a greater fitness as they become well adapted to escaping from predators better than the large spotted fish, which gives confers on them a greater fitness to be selected for against the large spotted fish.
<u>3. 15 large spotted fish move into this population:</u>
The movement or introduction of new individuals i<u>
</u>nto a population is what is referred to as <u>gene flow</u> in evolution, which is another mechanism of evolution that changes the allele frequency of the original population.
<u>4. Fish-eating birds catch large spotted fish more easily:</u>
This is another example of natural selection. The small spotted fish possess a greater fitness which makes them not easily preyed upon by Fish-eating bird easily, compared to large spotted fish. <u>Natural selection</u> favors the fish with small spotted alleles against the large spotted fish, and as a result, more small spotted fish would survive and reproduce more offspring with the small spotted alleles compared to those with large spotted alleles.
Answer:
the network of hydrogen bonding present between water molecules
Explanation:
a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
It’s dangerous for babies to be born early because not all of the baby’s organs and bones may have not developed fully yet. Premature babies could also develop a bunch of different health problems such as asthma or feeding problems.
