Describe the force of Earth’s gravity.

Answers

Answer 1

Answer

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

What might happen to the Earth if human increase the amount of greenhouse gasses?

Explain your answer.''

Answers

Answer:

Global warming will occur

Explanation:

Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.

Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.

which of the following is an example of a complementary base pair in DNA?
a. A-G
b. T-C
c. A-U
d. C-G

Answers

Answer: d. C-G

Explanation:

DNA or deoxyribonucleic acid is a structure which is common in every living organism. The two strands of the DNA are held together by base complementarity between the nitrogenous bases these bases are held by hydrogen bonding. Adenine always pairs with thymine by a triple hydrogen bonding and cytosine is always forms a pair with that of guanine by a double hydrogen bonding. So, in this given situation cytosine or C will show complementarity with that of guanine or G in a DNA structure helping in linking the two strands of DNA to form a single integrated double helical structure.

Where does ocean salt come from?
a. macrofungi
b. sporophere
c. roomology
d. mycology​

Answers

Ocean salt primarily comes from the evaporation of seawater, leaving behind the dissolved minerals and salts. It is not derived from macrofungi, sporophere, roomology, or mycology.

Ocean water contains dissolved salts and minerals, which are primarily derived from various sources such as weathering of rocks on land, volcanic activity, and underwater vents.

When the sun's energy heats the surface of the ocean, it causes the water to evaporate. Evaporation is the process by which water molecules escape into the atmosphere as water vapor.As the water vapor rises, it leaves behind the dissolved salts and minerals, which become concentrated in the remaining seawater.Over time, with continued evaporation, the concentration of salts and minerals in the remaining water increases.Eventually, the remaining water becomes supersaturated with salts, leading to the formation of salt crystals. These crystals can take the form of various salt compounds, such as sodium chloride (common table salt) and others.These salt crystals may precipitate and settle at the bottom of the ocean or accumulate in saltwater bodies, such as salt flats or salt pans.

Therefore, ocean salt is primarily a result of the evaporation of seawater, concentrating and leaving behind dissolved salts and minerals. It is not derived from macrofungi, sporophere, roomology, or mycology.

Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH is his real belts appear in the table below​

Answers

Answer:

B. Enzymes have particular pH's at which they function best

Explanation:

The table in this question describes the reaction rate of two enzymes (enzyme 1 and 2) measured in mmol/min. According to the question, Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH.

At pH 7-9, the reaction rate of enzyme 1 was more than that of enzyme 2 while from pH 9.5-11, the reverse was the case. This portrays that the reactivity of an enzyme is in response to the pH they are placed in. In other words, different enzymes have particular pH's at which they function best.

What type of conservation will result in the greatest reduction in the burning of fossil fuels?

Answers

Answer:

Conservation of air.

Explanation:

Conservation of air will result due to greatest decrease in the burning of fossil fuels because fossil fuels greatly damage the air. The burning of fossil fuels produces carbondioxide gas in large amount that can be released in the atmosphere. This increase in carbondioxide gas in the air causes pollution that leads to global warming as well as health problems in humans. So we can conclude that decrease the use of fossil fuel leads to conservation of air.

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels. This is so organs like the brain that use primarily glucose as their carbon source to produce energy via ATP have a steady supply of glucose. It also ensures that the levels of glucose in the blood stream do not get too high. Using the plots from problem 6, discuss why it makes sense that glucokinase in liver would behave differently than the hexokinase in other cells.

Answers

Answer:

Due to difference in function.

Explanation:

Glucokinase in liver behave differently than the hexokinase in other cells because glucokinase performs different function in the body. Glucokinase is an enzyme that is responsible for sensing the glucose level in the blood and also plays a key role in the storing of glucose as glycogen while on the other hand, this storing ability is absent in hexokinase so that's why the glucokinase in liver behave differently than the hexokinase in other cells.

Explanation:

As compared to old people, young people carry heavy burdens in terms of stress exposure. The daily activities such as house hold works, grocery shopping etc become a burden for young ones while the old age people are primarily affected by interpersonal conflicts, physical pain etc. Exposure of such daily hassles causes deterioration of health of both the young and old ones.

3. If muscle contraction were an athletic game, calcium would be the most valuable player. Describe,
using some depth, the roles calcium is serving both inside the muscle fiber and outside at the NMJ.

Answers

Answer:

Explanation:

At the NMJ, calcium is responsible for "unlocking" the ligand gated channels, allowing AcH to be released into the synaptic cleft. When AcH binds and the AP moves down the sarcolemma and into the t-tubule, calcium is then released from the sarcoplasmic reticulum into the sarcoplasm. It then binds to the calcium subunit of troponin, causing a confirmational change in tropomyosin, exposing the active sites on actin. This allows the myosin heads to bind, causing muscle contraction.
