Answer:

Creationists believe that a god created everything in the universe, including all life. Typically they don't believe in evolution; they believe that their deity created every species exactly how it's supposed to be and they don't need to change. They believe that everything in nature happens for a planned reason.

Naturalists believe that everything in the universe happens by chance. They believe in theories like the Big Bang Theory, which states that the universe itself was created by chance. They also believe in evolution - that every species adapts to its surroundings and evolves more desirable traits. Naturalists believe that the first life happened due to the correct conditions coming together by chance to create unicellular organisms, which eventually reproduced, mutated, and evolved into the millions of specialized species that exist on earth now.

Answer:

Letter C is the correct answer Good luck study love your eyes

Answer:

Dolphins are mammals, not fish. Unlike fish, who breathe through gills, dolphins breathe air using lungs.

They don't have gills, so they can't breathe underwater like fish. They breathe through a set of nostrils on top of their heads known as a blowhole. While swimming or resting under the water, they can take breathes by exposing only the tops of their heads to the air.

Like all mammals, dolphins have lungs and breathe air. They are the organ of the respiratory system which process the air inhaled through the spiracle.

In both erosional and depositional plains, there is the movement of soil from one point to another.

An erosional plain is formed when rock moves unto a higher area. It is different from depositional plains in which debris move away.

Hence, in both erosional and depositional plains, there is the movement of soil from one point to another.

Answer:

It would lower the pH of the oceans.

Explanation:

When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact.

CO2 emissions are also making the ocean more acidic, making many marine species and ecosystems increasingly vulnerable. Ocean acidification reduces the ability of marine organisms, such as corals, plankton and shellfish, to build their shells and skeletal structures.

Answer:

They are co-dominance and incomplete dominance.

Explanation:

Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.

Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.

The Trace Materials Unit uses methods and techniques to predict items of evidence. Instrumental methods are considered faster in providing results as compared to traditional chemical analysis.

Instrumental analysis is a field of analytical chemistry that helps to investigate analytes using some sort of scientific instrument.

Many of the instrumental methods can be done for both qualitative and quantitative analysis.

The major categories of instrumental methods are as follows:

Instrumental methods are considered much faster at producing results as compared to traditional chemical analysis. This factor is often important during a crime investigation.

Thus, the instrumental method is considered better as compared to chemical analysis.

The Nucleus is the cell structure that contains chromosomes which hold the genetic information of the individual.

DNA stands for Deoxyribonucleic acid. It is one of the most common types of genetic material in most organisms. It is found in both forms single-stranded or double-stranded.

Chromosomes are made up of tightly coiled DNA and consist of proteins known as histone proteins and provide all the master instructions to the cells.

Therefore, the chromosome inside the nucleus is the cell structure made of DNA that gives all of the master instructions for the cell.

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.

Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.

Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.
