Answer:
Stabilizing selection is occurring because the average is favored.
Explanation:
There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
Balancing selection, also called Stabilizing selection, eliminates individual with extreme traits and favors individual that exhibit medium-range characteristics, that gets to survive.
In the exposed example, babies with very low or very high birth weight have fewer possibilities to survive. Stabilizing selection eliminates individuals with extreme weight and favors individuals that exhibit medium weight, which are the ones that get to survive.

what is the center of the DNA strand?
Answer:
It exhibits traits and metabolic instructions of the cell.
Explanation:
A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.

Fruits vegetables and grains should be washed thoroughly
“It is not always possible to find or buy organic fruits and vegetables in today's conditions. In order to purify pesticide residues in foods, the first thing that is usually done at home is to put these foods in vinegar water. However, vinegar water is not effective in reducing pesticide residues, but in reducing the microorganism burden. Studies have done that vinegar water increases the effectiveness of pesticide residues even more. The main purpose of adding vinegar to the washing water is to create an acidic washing environment and to remove the potentially harmful biological factors that can be found on the food in case of inadequate washing. However, many of the pesticides commonly used today cannot be removed from the food due to insufficient washing and are taken into thBe body. This causes pesticides to continue their harmful effects for long periods of time.
Answer:
Fruits, Vegetables and grains should be washed thoroughly to wash off any germs on them. It is really important to wash them to remove any harmful bacteria off them. These bacteria can be really dangerous for our stomach and can cause different diseases. Peeling them is also a way to remove bacteria.

all plants give out oxygen during day and carbon dioxide during 9 to you agree with this statement give reason
Answer:
Yes, I agree with the given statement.
Explanation:
Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.

Mid-ocean ridges mark locations.
Answer:
its b i took the test
Explanation:
Subduction describes convergent boundaries.
What is convergent boundaries?Lithospheric plate borders that are convergent are those where the plates are moving in the same direction. These regions' plate clashes have the potential to cause earthquakes, volcanic eruptions, and crustal deformation.
The thicker, less dense continental plate pushes aside the thinner, more dense oceanic plate when the two plates contact. Subduction is the process by which the oceanic plate is pressed into the mantle.
The oceanic plate is pushed into regions with increasing temperatures as it falls. Materials in the subducting plate start to approach their melting temperatures and partial melting starts to take place at a depth of around 100 miles (160 km).
Therefore, Subduction describes convergent boundaries.
