Answer:
c. Plants continually add energy to an ecosystem using photosynthesis, which converts the sun's energy into usable energy.
Explanation:
The first thermodynamic law states that energy does not create or destroy, it transforms. The total energy in an isolated system keeps invariable, but the quality of the energy (exergy) might vary. The second thermodynamic law stated that if there is any process in a system there, the energy quality (exergy) must degrade. Any real process might only proceed in one direction that conducts to an increase in entropy. Entropy: Thermodynamic magnitude that indicates the degree of the molecular disorder in a system.Exergy: Measure of the maximum capacity of an energy system to produce useful work from a certain energy amount, as it balances with its environment.Ecosystems are the biotic, physical, and chemical components of nature, acting together as disipative processes out of balance. According to the second thermodynamic low, ecosystem development should increase the degradation of energy.
Vegetable growth helps to capture solar energy and dissipate useful gradients. Many times, plants of many species are arranged in such a way that they increase together the foliar surface to optimize capture and energy degradation. Most of the plants´ energy is destined to evapotranspiration, which is the main dissipative pathway in terrestrial ecosystems
The geographical distribution of species richness is highly correlated to the annual evapotranspiration potential. This relationship between species and exergy suggests a close link between biodiversity and dissipative processes. The more exergy is available among species, the more available energy degrading paths will be. Trophic levels and food chains are based on fixed photosynthetic material and the subsequent dissipation of those gradients. There will be a higher species´diversity in places where there is more available exergy.

Can earthquakes and volcanoes lead to landslides?
Answer:
Yes
Explanation:
The force and vibration from an earthquake or volcano can cause a landslide. An earthquake can shake the ground vigorously and cause rocks and dirt on mountains to break apart and start to fall down, causing the landslide.
What is the purpose of statistical analysis?
Answer:
Explanation: Statistical analysis is the process of generating statistics from stored data and analyzing the results to deduce or infer meaning about the underlying dataset or the reality that it attempts to describe.
Josh the postmen has eleven red rubber bands. He gives Sunita three bands. Sunita now has twice the number of bands Josh has left. How many bands did Sunita have at the beginning?
Answer:
13
Explanation:
We know that Josh starts with 11 rubber bands and gives away 3. This means that he now has 8 left (11-3=8). Sunita now has the extra 3 which means she now has twice the amount Josh has left. Since we know Josh has 8 left, we can work out that Sunita now has 16 (8x2=16). However this is not how many she had at the beginning as she recieved 3 from Josh. Therefore we can subtract 3 from her current number (16) to find here original number:
16-3= 13
Sunita had 13 rubber bands at the beginning.
Hope this helped!

What are biomolecules?The nearly 30 trillion cells that make up the human body work together to carry out each of the vital processes of life. Numerous chemical compounds found inside the cells enable them to carry out these vital functions. Biomolecules are the name given to these chemical compounds.
Biomolecules come in a broad variety of shapes and sizes and are engaged in a huge variety of biological processes. They are made up of more than 25 naturally occurring elements, with carbon, hydrogen, oxygen, phosphorus, and sulfur serving as the main ones.
Biomolecule production involves carbon compounds significantly. They combine covalently to create a number of different chemicals. When functional groups like alcohols, amines, aldehydes, ketones, and carboxylic groups are used to replace hydrogen atoms in hydrocarbons, certain biomolecules are referred to be derivatives of hydrocarbons.
Therefore the correct options are 1) A, B, and C; 2) C; 3) B; 4) B.

Can someone write a paragraph explaining Etiolation. PLEASEEEE
Etioliation means that you water plants that are planted in an area with little to no sunlight. This results in weak stems, smaller leaves, yellow color, etc. The seedlings that are grown in the dark are known as "skotomorphogenesis." Etiolation comes from something called "Auxin's" and Auxin's are moved from the top of the plant to the bottom which creates lateral buds. Typically, etiliation results in the chances being raised for the plant to receive sunlight but causes underiable symptoms.
Best of Luck!

All of the following occur during exercise in order to maintain blood glucose levels, except ______?a. Sympathetic stimulation causes an increase in insulin secretionb. Sympathetic stimulation causes the release of epinephrine and glucagonc. Epinephrine causes the breakdown of glycogen in muscle cells to glucosed. Epinephrine and sympathetic stimulation increase the breakdown of lipids
Answer:
a. Sympathetic stimulation causes an increase in insulin secretion
Explanation:
During exercise glucose is used up by the body especially muscle cells. This leads to the feeling of tiredness normally experienced.
Sympathetic stimulation causing an increase in insulin secretion doesn’t take place as insulin is used for metabolism of food substances and exercise doesn’t require food intake.
Sympathetic stimulation causes the release of epinephrine and glucagon I order to stimulate more glucose production during exercises.
Epinephrine causes the breakdown of glycogen in muscle cells to glucose is also true.
Epinephrine and sympathetic stimulation increase the breakdown of lipids. The breakdown of lipids aids in the production of energy needed by the body cells.
What happens when pyruvate is converted to lactate?
Answer:
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+
Explanation:
Pyruvate is converted to lactate by the enzyme lactate dehydrogenase under anaerobic condition.
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+ . This is because every glucose molecule that will be converted into pyruvate, two NADH molecules are produced and there is need for the NADH molecules to be oxidised back to NAD+ to ensure the continuity and maintenance of glycolysis.

Test tubes: This is a narrow tube container that is used to contain the sample, for heating and reaction.$ 4000 in a mutual fund earns 12% every year. How much will the fund be worth in 20 years?
solve with exponential function
Answer:
44092.705
Explanation:
Initial amount = 4000
Rate of increase = 12%
Time or period = 20 years
Using the exponential function with the relation :
A = Po * e^rt
Where ; A = final amount ; r = rate ; t = period ; Po = Initial amount
A = 4000 × e^(0.12*20)
A = 4000 * e^(2.4)
A = 4000*11.023176
A = 44092.705

Anyone know the answer
A new species was discovered in the deep jungles of Venezuela. In order to properly name the newly discovered organism, scientists needed to correctly classify it based on certain characteristics that they observed. This organism is capable of movement, performing photosynthesis with chloroplasts, and it also has ribosomes. Using these features, justify your choice of kingdom and why it is not the other kingdoms
Answer:
Kingdom Plantae
Explanation:
According to this question, a new species which possess characteristics including; ability to move, ability to photosynthesize via chloroplast, possession of ribosomes etc, was discovered in the deep jungles of Venezuela. This organism will likely belong to the KINGDOM PLANTAE because of its unique ability to photosynthesize and move.
-This organism cannot be a FUNGI because all fungi are heterotrophic
- This organism cannot be a BACTERIA because bacteria do not possess chloroplast, which is an eukaryotic organelle.
- This organism cannot be an ANIMAL because animals cannot photosynthesize.
- This organism cannot be an ARCHAEBACTERIA because archeans are prokaryotic, hence cannot possess chloroplast

Explanation:
The main body systems that would be involved in muscular dystrophy disease will be A. nervous, muscular, and respiratory.
Muscular dystrophy refers to the neuromuscular disease that weakens a person's muscles. This disease brings about weakness and the loss of muscle mass.It should be noted that when a person has muscular dystrophy, there'll be abnormal genes that'll interfere with how the body system works which makes the person unhealthy.It should be noted that when the muscles are weaker, the person affected will need a wheelchair or might have difficulties breathing. The disease affects the nervous, muscular, and respiratory systems.In conclusion, surgery is needed to treat the person affected.
