Explanation:
The difference between a pH of 5 and a pH of 8 is
Group of answer choices
A) 3x
B) 30x
C) 100x
D) 1,000x
Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the H+ concentration in acidity/basicity. The more H + ions found in solution, the more acidic the substance is as acids donate H + ions.
You can calculate the concentration of H + from the pH and the equation
p H = − log [ H + ]
arrange again
[ H + ] = 10 − p H
So for a pH of 8, we get [ H + ] = 10 ^− 8
For a pH of 5, we get [ H + ] = 10^ − 5
10 ^−5 /10 ^− 8= 10 ^3
= 1000
identifying earths four spheres
match each of earths spheres
Answer:
cryosphere → glaciers, ice caps, ice bergs
atmosphere → air surrounding earth
biosphere → all of Earth's living things
geosphere → Earth's interior, rocks, minerals, and landforms
hydrosphere → oceans, lakes, rivers, streams, and groundwater
Explanation:
The above are properly matched.
Cryosphere is known as part of the earth were water is in solid form. This has to do with glaciers, ice, ice bergs, etc.
Atmosphere has to do with the part of the earth that is gaseous. This has to do with the air found on earth.
Biosphere is the living part of the earth. All things are found in the biosphere.
Geosphere is known to be earth itself which is made up of the landforms, rocks, minerals, earth's interior, etc.
Hydrosphere has to do with the liquid part of the earth. It has to do with the water bodies.

__describes non-seasonal changed in the structure or composition of an ecological community over time
Ecological succession
Community ecology
Ecosystem dynamics
Answer:
Ecological succession
Explanation:
In ecology, ecological succession is described as a series of change in the structure or composition of an ecological community over a period of time. There are two types of ecological succession namely: primary succession and secondary succession.
Primary succession occurs on a barren land with no prior growth while secondary succession occurs in an area that has been colonized before but disturbed by an environmental hazard.
What is the answer with explaining
Answer:
Man (dimples and freckles) - FfDd
Woman (no dimples and no freckles) - ffdd
Child (no dimples and no freckles) - ffdd
Explanation:
According to this question, the possession of freckles (F) and dimples (D) are the dominant traits. The union of a man with dimples and freckles and a woman with no dimples and freckles (ffdd) gave rise to a child that has no dimples or freckles (ffdd).
Since the child has a recessive 'ffdd' genotype, it means that the father will likely have a heterozygous genotype (FfDd). Therefore, the genotypes of the three persons involved are;
- Man (dimples and freckles) - FfDd
- Woman (no dimples and no freckles) - ffdd
- Child (no dimples and no freckles) - ffdd

They expel carbon dioxide and inspire oxygen into our bodies, a process known as inspiration or inhalation (called expiration, or exhalation). The process of breathing involves the exchange of oxygen and carbon dioxide.Which of the following performs the function of respiration?The network of organs in the human respiratory system is in charge of absorbing oxygen and exhaling carbon dioxide. The lungs, which perform this gas exchange as we breathe, are its main organs. All of the body's cells are supplied with oxygen-rich blood by the circulatory system and the lungs.Learn more about respiration here:

Mass of the moon is 7.4x10^22 kg and its radius is 1740km, Calculate the value of acceleration due to gravity on the surface of the moon. *
Answer:
The gravitational acceleration in the surface of the moon is 1.63 m/s^2
Explanation:
The gravitational acceleration at a distance R of an object of mass M, is given by:
g = G*M/R^2
Where:
G is the gravitational constant.
G = 6.67*10^(-11) m^3/(kg*s^2)
We could think that all the mass of the moon is at its center, then at the surface of the moon, the distance will be equal to the radius of the moon, thus:
R = 1740km
But we want to work with meters, so remember that:
1km = 1000m
then:
1740km = (1740)*1000m = 1740000m
R = 1740000m
And the mass is just:
M = 7.4x10^22 kg
If we input all that in the gravitational acceleration equation, we get:
g = (6.67*10^(-11) m^3/(kg*s^2))*(7.4x10^22 kg)/( 1740000m)^2
g = 1.63 m/s^2
The gravitational acceleration in the surface of the moon is 1.63 m/s^2

Plants as well as brown, green, and red algae show a basic life cycle which involves the alternation of generations between a(n) egg and a sperm. seed and a cone. spore and pollen. megaspore and a microspore. sporophyte and a gametophyte.
Answer:
The correct answer is ''sporophyte and a gametophyte''
Explanation:
Plants have a diplohaplon life cycle: a haploid adult plant, called a gametophyte, and a diploid adult plant, called a sporophyte. In green algae, the two generations, sporophyte and gametophyte, are independent and generally the same size. This type of life cycle is found not only in many multicellular green algae, but also in brown algae and red algae. In vascular seedless plants, including ferns, gametophytes, although still independent, are smaller in size than sporophytes. In seed plants, the gametophytic generation is further reduced and is totally dependent on the sporophyte.

Complete tetanus occurs when the muscle is stimulated repeatedly at a high rate, eliminating a relaxation phase, the amount of tension gradually increases to a steady maximum tension.
What is Complete tetanus?A tetanic contraction is also called as tetanized state, tetanus, or the physiologic tetanus, the latter is used to differentiate from the disease called tetanus, which is a sustained muscle contraction that is evoked when the motor nerve which innervates a skeletal muscle emits action potentials at a very high rate than usual action potential production rate.
Complete tetanus is also called fused tetanus. It occurs when the frequency of stimuli increases still further than normal. In this case, the individual muscle contractions completely fuse to produce one large enough muscle contraction in the body.

What is the fate of pyruvate in the cytoplasm when oxygen is absent
Answer:
Pyruvate is turned to lactate via a process called fermentation
Explanation:
Pyruvate is the product of the initial stage of cellular respiration called GLYCOLYSIS. Pyruvate is produced in the cytoplasm where glycolysis occurs. The fate of pyruvate i.e. what will eventually happen to pyruvate, is determined by the presence or absence of oxygen.
In the absence of oxygen i.e. anaerobic condition, pyruvate is converted into lactate in a process called FERMENTATION. The NADH produced during glycolysis is reoxidized to form NAD+ in the process.

The enzyme lactate dehydrogenase is responsible for fermentation of pyruvate to form lactate. This process occurs in red blood cells and in muscle cells during intense exercise. Why is fermentation a necessary process for these cells to meet their energy needs
Answer:
Fermentation is a process that happens in the absence of oxygen and it involves the conversion of Pyruvate to lactate.
Cells in the body need constant energy supply to cater for the various demands of our everyday activities and to ensure that they function optimally.
Oxygen supply is an important factor in ATP generation and in cases where there is a lack of it the body system adjusts itself to produce the energy anaerobically. This usually involves the conversion of pyruvate to lactate which aids the breakdown of glucose thereby supplying it to cells of the body.
