Microbes and Bacteria can be killed more easily and so they cant hide in the little pores.
Explanation:
How does gene flow directly contribute to evolution?
Answer:
Evolution can also occur as a result of genes being transferred from one population to another. This gene flow occurs when there is migration. The loss or addition of people can easily change gene pool frequencies even if there are no other evolutionary mechanisms operating.

1. Effect: Radiogenic heat released- Cause: convection currents cycle through magma.
2. Effect: Earth has a powerful magnetic field- Cause: Iron in earths outer core swirls due to convection currents.
3. Effect: Tectonic plates move- Cause: unstable isotopes in earth release energy.
What is Convection current?Convection currents are defined as the result of differential heating where lighter, less dense, warmer materials rise while heavier, more dense, cooler materials sink. This is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the Earth's mantle.
Convection currents arise from differences in fluid density that arise due to a temperature gradient, resulting from the continuous replacement of the hot fluid in the region of the heat source with the nearby cold fluid which is known as the natural convection currents.
Thus, Radiogenic heat released- Cause: convection currents cycle through magma.

Suppose an individual giraffe could not reach high leaves on a tree
its neck was too short. Lamarck's theory would suggest that the giraffe could
undergo physical changes that would lengthen its neck simply by stretching
to reach the branches. What experimental result would disprove this?
E The necks of giraffes today are shorter than the necks of early giraffes.
G. Giraffes with longer necks prefer to eat leaves from higher branches.
H. Neck lengtı does not change when giraffes are fed branches at different
heights.
1. Giraffes with longer necks frequently produce offspring that also have
longer necks.

In the past, pacific sea otters were hunted to near extinction.
Without the otters, kelp forests along the coast started to die
because sea urchins, the otter's favourite food, were able to
overgraze them. Once otters became protected, the kelp
forests began to recover as the urchins were back in check.
In this kelp forest ecosystem, sea otters are a ________

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.
Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
It decreases cost of production on the crop as well as increase production.
Explanation:
It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.
Answer:
One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.
