Life would end if every speck of carbon were turned into biomass.
It is because there wouldn't be enough carbon in the atmosphere for plants to carry out life processes. The carbon is substitute of all biomolecules. These biomolecules carries out all vital function.
Alternative energy sources to fossil fuels like coal, petroleum, and natural gas include biomass and the biofuels derived from it. Carbon dioxide (CO₂), a greenhouse gas, is released during the burning of either fossil fuels or biomass. However, the plants that provide the energy-producing biomass collect nearly as much CO₂ through photosynthesis as is produced when the biomass is burned, making biomass a carbon-neutral energy source.
Hence, carbon should be balanced between abiotic and biotic component

If one ounce is approximately equal to 28 grams, then one pound is approximately equal to
a. 250 grams
b. 350 grams
c. 450 grams
d. 550 grams
e. 650 grams
One pound will be approximately equal to = Option c) 450 grams
An ounce is considered the value for calculating mass in the imperial method of measurement
The value of one ounce is approximately equal to = 28.3495 grams
Same as in the case of pounds,
1 pound = 16 ounces
As we have seen that the value of an ounce is approximately 28 grams so calculating one pound in grams
= 16 x 28.3495
= 453.592 grams

explain how the following processes are impacted by the insulin/glucagon system glucose transport all tissues g
When blood sugar is too low the pancreas releases glucagon. Glucagon directs the liver to release stored glucose increasing blood sugar levels in the body.
Like a lock on a lock, insulin binds to cell surface receptors and directs GLUT4 molecules to the cell surface. As the name suggests, glucose transport proteins act as vehicles for the uptake of glucose into cells. The two hormones counterbalance each other to stabilize blood glucose.
Insulin inhibits gluconeogenesis and glycogenolysis stimulates glycolysis and gluconeogenesis and transfers amino acids Stimulates uptake and uptake inhibits proteolysis stimulates lipogenesis and inhibits lipolysis. Glucagon keeps blood sugar from getting too low while insulin is produced to keep blood sugar from getting too high.

During the 1950s, a scientist named Lysenko tried to solve the food shortages in the Soviet Union by breeding wheat that could grow in Siberia. He theorized that if individual wheat plants were exposed to cold, they would develop additional cold tolerance and pass it to their offspring. Based on the ideas of artificial and natural selection, do you think this project worked as planned?
No, because there was no process of selection based on inherited traits. Lysenko assumed that exposure could induce a plant to develop additional cold tolerance and that this tolerance would be passed to the plant's offspring.
Based on the ideas of artificial and natural selection, this project didn't work as planned C. because there was no process of selection based on inherited traits.
Trofim Lysenko was a biologist in the Soviet Union at the time who was opposed to the fundamental principles of science. Humans developed selective breeding as a means of achieving desired outcomes by altering specific species' characteristics. This is based on the idea that genes in living things contain traits that can be passed down from one generation to the next.
Lysenko refuted this assertion. He was more of a firm believer that animals and plants can quickly adapt to their surroundings and develop traits that they can then pass on to their offspring. When he exposed wheat plants to cold, he used this theory to predict that they would become cold-tolerant. Millions of people in the Soviet Union perished as a result of severe starvation and this woefully failed.

He theorized that if individual wheat plants were exposed to cold, they would develop additional cold tolerance and pass it to their offspring. Based on the ideas of artificial and natural selection, do you think this project worked as planned?A. Yes; the wheat probably evolved better cold tolerance over time through inheritance of acquired characteristics.
B. No, because Lysenko took his wheat seeds straight to Siberia instead of exposing them incrementally to cold.

In concentrated (hypertonic) solutions, water _____ the cells
In concentrated (hypertonic) solutions, water moves out of the cells. There is a net flow of water out of the cell and cell loses its volume.
What is a hypertonic solution?
A hypotonic solution is a solution which has lower osmotic pressure than the solution outside to which it is compared. It may also mean a solution which contains a lower amount of solute concentration as compared with the solute concentration in the other solution which is present across a semipermeable membrane.
In a hypertonic solution, there is a net movement of water out of the cell body and into the solution in which the cell is placed. A cell placed into a hypertonic solution will shrink and die by a process known as plasmolysis which results into reduction of cell volume.

4. A car of mass 800 kg accelerates from 5m / s to 25m / s in 10 s. a) Calculate the acceleration. b) Calculate the resultant force exerted.
Answer: To calculate the acceleration of the car, we can use the equation:
acceleration = (final velocity - initial velocity) / time
Plugging in the values given in the question, we get:
acceleration = (25 m/s - 5 m/s) / 10 s = 2 m/s^2
To calculate the resultant force exerted on the car, we can use the equation:
resultant force = mass * acceleration
Plugging in the values given in the question, we get:
resultant force = 800 kg * 2 m/s^2 = 1600 N
This is the force that must be exerted on the car to accelerate it from 5 m/s to 25 m/s in 10 s.
A) As, the accelerarion equation is V - U/t
so its 25-5/10 so its 2m/s^2
B) With the above answer in A) we can calculate the force with the equation f = m * a
so , 800*2 = 1600N

What is an approximate interval?If you know the exact distribution of the test statistic, and use that distribution's quantiles to make confidence intervals, that interval is exact. If you approximate the distribution of the test statistic, then the interval is approximate.The Empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated belowThe Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
68% of data falls within the first standard deviation from the mean.95% fall within two standard deviations.99.7% fall within three standard deviations.From the information given, the mean is $150 and the standard deviation is $20.2 standard deviations = 2 × 20 = 40
150 - 40 = $110
150 + 40 = 190

Mean = 150
Standard deviation = 20
95% of the monthly food expenditures are between what two amounts:By the Empirical Rule, within 2 standard deviations of the mean150 - 2*20 = $110

In mammals, antidiuretic hormone (ADH) is essential for maintaining homeostasis. In response to high tissue osmolarity, the hypothalamus releases ADH. The collecting duct and distal tubule in the kidney become more permeable to water in response to ADH, increasing water reabsorption into the capillaries.
Antidiuretic hormone is a brain chemical that causes the kidneys to release less water, reducing the amount of urine produced. When the ADH level is high, the body produces less urine. A low level causes more urine production. Desmopressin is a synthetic form of vasopressin, an antidiuretic hormone.

Option c is the appropriate response. With respiratory compensation, acid-base conditions caused by starvation would result in metabolic acidosis.
Respiration and metabolism are interdependent. Metabolic compensation and respiratory acidosis or alkalosis go hand in hand. Similar to metabolic alkalosis, respiratory compensation is related to metabolic acidosis. Within cells, a process known as cellular respiration uses enzymatic pathways (such as glycolysis and the Krebs cycle) to break down glucose, releasing water, carbon dioxide, and ATP in the process. Direct responses to metabolic demands are made through respiration. The lungs carry out a number of metabolic processes, such as gas exchange, the inactivation of vasoactive chemicals, the conversion of angiotensin I to angiotensin II by the angiotensin-converting enzyme (ACE), and protein synthesis.
