Explain why it is important to monitor environmental parameters when making policies involving resource use.
Answers
Answer:
Environmental parameters indicate whether or not resource use is harming the environment and this way monitoring environmental parameters affect policies regarding resource use.
Explanation:
Answer:
Human activity has an impact on the environment. In order to minimize the impact of human activity it is important to understand factors that affect the environment. It is also important to know how different human activities affect those environmental factors. This knowledge can be obtained by monitoring specific environmental parameters. For resource use, specifically, it is important to monitor changes in the environment to decide the level and frequency of resource use in certain areas.

In January, Earth is closest to the Sun in its orbit. Yet the Northern Hemisphere experiences winter. Which statement explains this phenomenon?
A.
Earth completes one precession cycle in January every year.
B.
The Northern Hemisphere is located at high latitudes.
C.
The Northern Hemisphere is tilted away from the Sun.
D.
The eccentricity of Earth’s orbit is high in January.
E.
The obliquity or tilt of Earth is greater than 23.5° in January.
Answers
Answer:
C. The Northern Hemisphere is tilted away from the sun
In January, Earth is closest to the Sun in its orbit, yet the Northern Hemisphere experiences winter because the Northern Hemisphere is tilted away from the Sun; this is option C.
What is Earth's axis tilt?The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to the plane of its orbit around the Sun. This tilt is the primary reason for the seasons on Earth. As the Earth orbits around the Sun, the orientation of its axis relative to the Sun changes, resulting in different parts of the planet receiving varying amounts of sunlight throughout the year. When the Northern Hemisphere is tilted away from the Sun, as it is in January, the Sun's rays hit the Earth at a lower angle, resulting in less direct and less intense heat and light. This means that the Northern Hemisphere receives less sunlight and experiences colder temperatures, resulting in winter.
Hence, in January, Earth is closest to the Sun in its orbit, yet the Northern Hemisphere experiences winter because the Northern Hemisphere is tilted away from the Sun, which is option C.

I2 - Aa

I1 - AA
I2 - Aa
C
I1 - Aa
I2 - aa
D
I1 - aa
I2 - AA
( please explain, this is a test prep question and I really need help with it. )
Answers
Answer:
C. Aa and aa
Explanation:
The question tell us that shaded symbols represent individuals who express a dominant trait (or phenotype). This means that symbols that are not shaded represent individuals who express a recessive trait (or phenotype).
A dominant allele (A in this case) will always mask a recessive allele (a in this case) when present and be shown in the organism's phenotype. Therefore genotypes AA and Aa, which both contain the dominant allele A, will both result in dominant phenotypes, while the genotype aa will result in a recessive one due to the absence of a dominant A allele.
Looking at the pedigree chart we can see that individual 1 has a dominant phenotype, and individual 2, a recessive phenotype. Since the only way for an organism to have a recessive phenotype is to only have recessive alleles, organism 2 must have genotype aa. Similarly organism 1 must have at least one dominant A allele, therefore C is the correct answer.

ANSWER: A NATURAL SELECTION.
EXPLANATION:
When allele has direct effects on the organism and the environment, it is termed natural selection. It either affects an organism positively by causing more DNA reproduction, leading to the increase in allele’s frequency, or negatively by decreasing it .
However, this shouldn't be mistakened for genetic drift, where allele increase or decrease is established in the random organisms that survived.

Answers
Answer:
y. 2. • CxHy + O2 → x CO2 + y/2 H2O. Combustion Problem. Erythrose is an important mono-saccharide that is used in chemical synthesis. It contains Carbon.
Explanation:
In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction, here Y is the glucose, and this X is carbon dioxide, and this is a reaction of the photosynthesis.
What is photosynthesis?During photosynthesis, the energy from light is used to split water molecules into oxygen and hydrogen ions. The oxygen is released into the atmosphere as a waste product, while the hydrogen ions are used to create a chemical gradient across the thylakoid membrane within the chloroplast. This gradient is then used to power the creation of ATP, the energy currency of cells, as well as to reduce carbon dioxide to form organic molecules, such as glucose. The overall equation for photosynthesis is:
6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂
Hence, In the chemical equation X + H₂O → Y + O₂, Y represents the product of the chemical reaction; here, Y is the glucose.
