Why is acid precipitation such a problem all around the world?

Biology

Acid rain is linked to both natural and man-made sources. Nitrogen oxides are formed through the extreme heating of air when a thunderstorm produces lightning. Also, sulfurous gases are discharged from erupted volcanoes and rotting vegetation. ... For this reason, acid rain is considered a global problem.

Acid rain can be very problematic, because many environments can’t handle the change to their ph levels. Wildlife such as forests and ponds have been greatly devastated by these means, which forces many animals out of their habitats. Acid precipitation can also have an effect on buildings and man-made structures, because of the materials they are built with. As an example, many medieval sculptures made out of sandstone have been detrimentally damaged from acidic rain. Not only can it hurt the environment, but also thwarts the acquisition of historical knowledge. Hope this helps!!

Schach [20]

The red blood corpuscles have a pigment called hemoglobin that binds to the oxygen and carries it to the whole body in both the conditions, when the body is at rest or when the body is exercising. The oxygenated blood from the heart is carried to the various parts of the body and the de-oxygenated blood from various parts of the body is carried to the lungs where the exchange of gases takes place.

A decrease in the resting membrane potential is __________ whereas, __________ is an increase in the membrane potential.
nexus9112 [7]

Answer: depolarization; hyperpolarization

Explanation:

At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.

However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.

An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.

4. Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If t
lisov135 [29]

Answer:

The correct answer would be:

  • Genotype ratio: 1 (PP) : 2 (Pp) : 1 (pp)
  • Phenotypic ratio: 3 (polka-dot tails) : solid colored tail

The genotype of both parents is Pp (heterozygous).

Thus, both the parent would produce two types of gametes which are P and p.

The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.

Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.

Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).

How humans have contributed to the extinction of plant or animal species?
VashaNatasha [74]

Answer: The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.
