Explanation:
The pH value is a unit of measure which describes the degree of acidity or alkalinity of an aqueous solution. In other words, pH demonstrates the quantitative information of the activity of an acid or base based on hydrogen ion concentration.
The mathematically formal definition of pH is the negative logarithm of hydrogen ion concentration:
[tex]pH \ \ = \ \ -\log_{10}\left[H^{+}\right][/tex].
Hence, if the concentration of [tex]\text{H}^{+}[/tex] ions in a solution is [tex]1.0 \ \times \ {10}^{-7} \ \text{M}[/tex],
[tex]pH \ = \ -\log_{10}\displaystyle{\left(1 \ \times \ {10}^{-7}\right)} \\ \\ pH \ = \ -\log_{10}\displaystyle{\left(1\right) \ - \ \log_{10}\left({10}^{-7}\right)} \\ \\ pH \ = \ 0 \ - \ \left(-7\right) \\ \\ pH \ = \ 7[/tex].

a. True
b. False
Answers
Hormones are chemicals made in the soil that affect parts of plants. The statement is false.
How are gibberellins able to affect other parts of the plant?Gibberellins stimulate the growth of shoots which increase the biomass and vegetative growth of plants. If vegetative growth increases, the root biomass is also increases.
So we can conclude that other parts of the plant are also affected due to gibberellin because it stimulates the growth of shoots which is the upper portion of the plant.

Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of C. adaptive radiation.
What is common ancestry?Common ancestry refers to blood relationships. Thus, two species may have common ancestry if they are related by blood.
According to Charles Darwin, common ancestry explains the similarities between different species.
However, a rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity results from adaptive radiation.

Inner Canyon North Rim
average elevation 2,100 feet 8,000 feet

average temperature in January 56°F 37°F
Why is there such a vast climate difference in these two areas of the Grand Canyon?
Answers
The average temperature in July 107°F 77°F. Thus, the correct option is C.
What is the average high temperature in the inner Grand Canyon?With a 34°F minimum and a 62°F maximum temperature. Phantom Ranch's inner-canyon temperatures typically vary from a low of 55°F to a high of 82°F. Summer (June–August) temperatures range from a little over 100°F (38°C) at the Grand Canyon's bottom to 80+°F (plus or minus) at the South Rim.
Around 1,500 feet higher than the South Rim, the North Rim is perched above the Kaibab Plateau at an altitude of between 8,000 and 9,000 feet.
On February 1st, 1985, the North Rim had a record-low temperature of -22 °F. At Phantom Ranch, the temperature reached 120°F on a number of occasions during the summer. Rough topography and deep gorges have a significant impact on solar heating and air movement. As a result, the canyon contains numerous unique microclimates.

Provide an environment (bowl or container) filled with 100 of each "prey" type (Consider beans, uncooked pasta, or cotton balls). Give yourself a minute to "catch" the "prey" with each "predator" separately (total of 3 minutes). Place each "prey" that is caught into a cup. Count your results after each "predator" simulation.
Which prey was the best adapted? What data do you have to support this?
In what ways does this activity demonstrate the process of natural selection and its consequences?
Answers
The activity demonstrated natural selection as the beans will most likely survive since they are better suited to their environment .
What is natural selection?Natural selection is the process which organisms which are better adapted to their environment survive and reproduce while those not adapted die.
In the simulation, the "prey" are beans, uncooked pasta, and cotton balls. The predators are fork, knife, and a spoon.
Using the predators to pick up the prey, the beans were more adapted as they escaped being caught the most, as they had the least number picked up.
Therefore, the beans will most likely survive, demonstrating natural selection which states that organisms better suited to their environment survive the most.

GENES are the fundamental unit of heredity that transmit albinism from one generation to the next. Thus, the correct option is A.
What is DNA?Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce.
Because they contain unique sets of instructions to encode certain proteins, which are passed down across generations, genes are regarded as the fundamental functional and structural components of heredity (i.e., they are inherited).
When a gene is expressed, certain DNA fragments (i.e., genes) are used as templates to produce messenger RNAs (mRNAs), which are complementary RNA sequences.
