The hydrogen ion concentration of the following pH samples is as follows:
7 (a neutral solution) = 0.8455.6 (unpolluted rainwater) = 0.7483.7 (first acid rain sample in North America) = 0.568How to calculate hydrogen ion concentration (H+)?The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.
The mathematical relationship between pH and H+ concentration ([H+]) is as follows:
pH = –log [H+]
This means that the hydrogen ion concentration (H+) of the following pH values can be calculated thus:
log 7 (a neutral solution) = 0.845log 5.6 (unpolluted rainwater) = 0.748log 3.7 (first acid rain sample in North America) = 0.568Learn more about pH at: https://brainly.com/question/15289741

Anita thinks that she has heterozygous alleles for red hair. if she is correct, which of these diagrams best illustrates anita’s alleles for red hair? 2 chromosomes are labeled upper r and upper r. 2 chromosomes are labeled upper r and r. one chromosome is labeled upper r and another is unlabeled. 2 chromosomes are labeled r and r.
Answer:
R r One uppercase R and one lowercase r
Explanation:
Heterozygous means having two different alleles. Since R is the dominant it means she has red hair and is still heterozygous.
Answer:
2 chromosomes are labeled R and r
Heterozygous means different, so you need two different traits.
One way in which photosynthesis would be affected if all the air spaces in the leaf were filled with cells
Carbon dioxide must flow from the air spaces into the leaf for photosynthesis to take place. By diffusing via tiny pores called stomata, it achieves this.
How gaseous exchange is affected if cells are filled in the air spaces.
Cells called stomata are found on the epidermis, or skin, of an above-ground plant. These cells allow water and oxygen to enter the plant while also allowing carbon dioxide to depart. The process through which plants absorb carbon dioxide and exhale oxygen as waste is known as photosynthesis. Intake of carbon dioxide reacts with water in the presence of sunlight to produce glucose and other molecules that are high in energy.If, air spaces are filled with the cells no exchange of gases takes place which does not allow plants to produce energy-rich compound glucose.To learn more about the photosynthesis, you can refer to-

O=P OT O This functional group consists of phosphorous bonded to three oxygens and double - bonded to one oxygen . Which functional group is shown in this image ? O = P OT O
The biomolecule which consists a functional group in which phosphorous bonded to three oxygens and double-bonded to one oxygen is Adenylic acid.
Adenylic acid is a nucleotide.
A nucleotide has three chemically distinct components.
One is a heterocyclic compound, the second is a monosaccharide and the third a phosphoric acid or phosphate unit.
It is a building block for a nucleic acid.
the heterocyclic compounds in nucleic acids are the nitrogenous bases named adenine, guanine, uracil, cytosine, and thymine. Adenine and Guanine are substituted purines while the rest are substituted pyrimidines. The skeletal heterocyclic ring is called as purine and pyrimidine respectively. The sugar found in polynucleotides is either ribose (a monosaccharide pentose) or 2' deoxyribose. A nucleic acid containing deoxyribose is called deoxyribonucleic acid (DNA) while that which contains ribose is called ribonucleic acid (RNA).

How is the law of conservation of mass applied to ecology?
Answer:
The laws of conservation of mass applies to ecology because the transfer of nutrients from organisms to the ground results in excess energy not disappearing
Answer: The law of conservation of mass states that the total amount of mass remains constant in a system. In ecology, this means that when an organism is eaten, its mass is conserved. Some of the organism’s mass is used to make new proteins, and some of it is passed as waste in the form of urine or feces. The rest is converted directly into energy. This energy helps the consumer to move and grow, and it helps it to build and repair new tissue.

2. Predict how your refined mining techniques could affect the social and environmental stability of the region.
Mining is the birth of minerals and other geological accouterments of profitable value from deposits on the Earth.
Mining negatively affects the terrain by converting loss of biodiversity, soil corrosion, and impurity of face water, groundwater, and soil. Mining can also spark the conformation of holes. The leakage of chemicals from mining spots can also have mischievous goods on the health of the population living at or around the mining point.In some countries, hidden-trapping companies are anticipated to cleave to recuperation and environmental canons to ensure that the area hidden-trapped is ultimately converted back into its original state. still, violations of similar rules are relatively common.Loss Of Biodiversity
frequently, the worst goods of mining conditioning are observed after the mining process has desisted. The destruction or drastic revision of the pre-mined geography can have a disastrous impact on the biodiversity of that area. Mining leads to a massive niche loss for a diversity of foliage and fauna ranging from soil microorganisms to large mammals. Aboriginal species are most oppressively affected since indeed the fewest dislocations in their niche can affect extermination or put them at high threat of being wiped out. poisons released through mining can wipe out entire populations of sensitive species.legislation related to mining-
There are different kinds of legislation. The legislation that needs land to be restored after mining tends to make mining to be veritably precious as it does so through the duty of some rules and regulations for the hidden-trapping companies.Through this, it handles the responsibility of their land declination and takes back the land to its original form. This process is known to contribute to the fiscal counteraccusations of a company.Why is it important to take land after mining?
Mining is known to be an act that disturbs the land. A lot of mines now are been known to reclaim the face in the course and after mining is completed, and therefore they return the land for useful purposes.
