The given statement is true.

A bulbourethral gland, also known as Cowper's gland, is one of the two small exocrine glands found in the male mammal's reproductive system. At the time of sexual arousal, the glands generate a mucus-like fluid known as pre-ejaculate.

The pre-ejaculate fluid is a clear, viscous, and salty liquid, which counterbalances any of the residual acidity in the urethra. The neutralized urethra offers a friendlier surrounding for the entry of the sperm.

How are energy inputs and outputs related to chemical reactions
GREYUIT [131]

The large number of areas covered by the chemical energetics can be explained by the different forms in which chemical energy can be released: heat and combustion work, electrical energy in electrochemistry, radiant energy in chemiluminescent systems.

The chemical energy provided by a reaction reflects the energy balance associated with the electronic modifications suffered by the species involved.

From an energy point of view, a chemical reaction between molecules can be schematized in two stages. The first requires a supply of energy and corresponds to the rupture of the bonds of the reactant molecules with release of the atoms which constitute them.

The second releases energy and concerns the creation, by recombination of these atoms, of new bonds entering the structure of the reaction molecules.

As a general rule, the energy released in the second stage is greater than the first. We are talking about exothermic reaction. The difference between these two energies (reaction enthalpy) measures the amount of chemical energy transferred to the external environment.

It is conceivable that this quantity translates, not only the number, but also the strength of the connections involved.

in one to three sentences describe what happens during the carbon fixation stage of the calvin cycle.
BaLLatris [955]

Answer:

In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively.

When 10,000 molecules of ATP are hydrolyzed to ADP and i in a test tube, about half as much heat is liberated as when a cell hyd
Korolek [52]

Answer:

C. Reactant and product concentrations in the test tube are different from those in the cell.

Explanation:

Cells convert some of the energy from ATP hydrolysis in to different forms of energy other than heat. ATP energy does not always generate more heat.  Many times, energy is used for different purposes.

Match the name of the greenhouse gas with one of the human activities that produces it.
Svet_ta [14]

Answer:

carbon dioxide- burning of fossil fuels

fluorinated gases- industrial processes

methane- production and transport of oil and natural

gas

nitrous oxide- agricultural and industrial activities

Explanation:

Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.

Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.

Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.

Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.

Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.

A muscle cell contracts or expands when
yanalaym [24]

Answer:

Walking

Explanation:

A muscle cell usually contracts or expands simultaneously when one is working or doing some activities like running, exercises, house chores e.t.c

Muscles are flexible fibers that are very essential appendages for locomotion in human beings.

For muscle cells to contract, they are pulled together thereby causing tension in the muscle. When they are relaxed, they move away from one another.
