[50 points... Will give brainliest] Explain how natural selection is impacted by genetic differences, variation, and survival.​

Answer:

This simply explain the concept of osmosis. A solution of 0.8% is lower in conc. (hypotonic)compare to that of 0..2%(hypertonic)Therefore, the inner cells layer would lose water to higher hypertonic concentrated medium.

      water flows from .8% to salt solution of 0.2%

This follows the concept of osmosis which is the movement of water molecule from the region of higher water potential(.08) to region of lower water potential(0.2) but high solute potential, through  a semiportable ,membrane, the plasma membrane.

Answer:

Walk to places as much as possible to reduce co2 emissions from cars.

Explanation:

The levels of carbon dioxide is higher in the atmosphere than it was before because of the human activities, which is eventually leading to global warming. Carbon dioxide being one of the most important greenhouse gases is present in abundant concentrations in the atmosphere and there is a need to reduce the levels to have some relief from global warming.  

Some of the ways of reducing the levels of carbon dioxide in the atmosphere are:  

• Planting more trees as trees are mainly good at storing carbon by the process of photosynthesis.

• Another way to use photosynthesis to fight against climate change is the use of bio-energy with carbon capture and storage technique. It is the process of utilizing biomass as the source of energy in the power sector.  

• Another way to capture carbon dioxide directly from the air is by chemically scrubbing carbon dioxide directly from the ambient air, and then storing it either in the long-lived products or underground.  

Thus, there are some techniques, which can be implemented to reduce the concentration of carbon dioxide from the atmosphere.

Answer:

In the dehydration synthesis reaction (attached) , two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose (macromolecule)

Explanation:

Macromolecules are formed from glucose by condensation polymerization.

Macromolecules are formed by the agglomeration of small molecules called monomers. These monomers are simple molecules that can be joined together to form a larger molecule.

Glucose can serve as a monomer that is joined together to yield macromolecules such as polysaccharides. These larger molecules are formed by the process of condensation polymerization in which a water molecule is lost.

The highest trophic levels are of hawks and that is because they will be subjected to the greatest biomagnification.

Biomagnification is an accumulation of substances for example like toxins or pesticides that are found intolerant organisms. It is increasing as the trophic levels of a food chain increase.

Answer:

The correct answer is - must be honest and without bias or later change.

Explanation:

In an experiment to get the reliable and desired result, one should get collect the data from all possible sources and note it down for reference. This data should not be bias or not influenced by any external factor and solely based on the experiment or associated with the experiment.

Data that is calculated should not be change or edit to support the result or if not getting the desired result. Data should remain unchanged for an honest and unbiased experiment or investigation.

Answer:

I-1 genotype = AA or Aa

I-2 genotype = aa

Explanation:

The trait in question is autosomal and dominant. Let us assume that the trait is represented by the allele A, the alternative form would be a.

I-1 individual is affected for the disease, hence he is either true-breeding AA or heterozygous Aa.

I-2 individual is not affected for the disease, hence, she can only be aa. For an autosomal dominant trait, an individual is either affected or free from the trait. There is no chance of being a carrier. Heterozygous individuals are affected for the disease.

Therefore;

I-1 genotype = AA or Aa

I-2 genotype = aa

Answer:

Unequal heating of the earth's surface causes temperature differences which cause pressure differences. Lower temperatures  cause higher air pressure. Wind direction is described as where the wind is coming from. For example a northerly wind blows from the north to the south. Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.
