Group of answer choices.
A. Only since humans appeared.
B. Repeatedly, rapidly and rarely.
C. Slowly, over billions of years.
D. Very little since Earth began.
Answer:
C. Slowly, over billions of years.
Explanation:
Environmental science can be defined as an interdisciplinary field of science that comprises of chemistry, economics, engineering, zoology, geography, geology, biology, ecology, physics, etc., used for the study and understanding of various environmental factors, issues in relation to human life.
Our understanding of both biology and geology is based on the idea that living things and environments have changed slowly, over billions of years.
This understanding is made possible through the study of the relationship between living organisms and their environment, as well with other forms of life found in the ecosystem.
An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Basically, scientist have been able to study the remains of various living organisms (fossils) from billions of years ago and discovered that the change between the living organisms and the environment occured slowly.

The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, ________.
Answer: The oxygen content of the water decreases
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.
The temperature and the salt content of a body of water determines how much oxygen it can hold.
The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.
Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.
Therefore, a warmer and saltier water will contain a less amount of oxygen.

The cellular mechanism that determines the independent assortment of maternal and paternal chromosomes is: Please choose the correct answer from the following choices, and then select the submit answer button. determined by their dominant or recessive inheritance pattern. separation of sister chromatids at anaphase II of meiosis. separation of sister chromatids at anaphase I of meiosis. separation of homologous pairs at anaphase II of meiosis. separation of homologous pairs at anaphase I of meiosis.
Answer:
separation of homologous pairs at anaphase I of meiosis.
Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend or influence the allele of another gene in the same gamete. This random distribution can only be applied to independent genes. These genes segregate independently after crossing over because they are located far away from each other.
When cell division is going on by meiosis, it involves the random and independent segregation of the alleles. During anaphase I (meiosis), the pairs of homologous chromosomes separate independently of each other. Each integrant of the homologous pair migrates to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. The process is as follows.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. During anaphase I, each of the homologous chromosomes migrate to the corresponding pole. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

Answer:
The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate.
Explanation:
A combination of conditions (factors) that caused these changes in the habitat are:
Hot summersHarsh wintersCold springs What is a habitat?A habitat refers to a combination of resources and geographical area that defines where the particular species of a living organism such as a rabbit, generally lives and thrives.
In this scenario, a combination of conditions (factors) that caused these changes in the habitat are:
