Calculate the rate of photosynthesis(mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 5 min and, when measuring cellular respiration it took 20 minutes for the water level to move down 1mm.
63mm/hr
57mm/hr
67mm/hr
61mm/hr
52mm/hr
Answer:
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

Which soil horizon has the least nutrients? why?
Answer: Subsoil
Explanations: This layer has normally less organic matter than the A horizon, so its colour is mainly derived from iron oxides. Iron oxides and clay minerals accumulate as a result of weathering.:
The____
gland controls water balance, growth, and blood pressure
pituitary
Thymus
thyroid
pancreas
Answer:
The pituitary gland controls water balance, growth and blood pressure.
Explanation:
The pituitary gland is also called hypophysis, and is a small gland located in the skull that is responsible for secreting hormones and coordinating the activity of other glands.
Hypophysis is usually divided into two portions, adenohypophysis or anterior lobe and neurohypophysis in posterior lobe. Among other functions, the pituitary gland is in charge of
Water balance and blood pressure, through the antidiuretic hormone or ADH secreted by the neuro-pituitary. Growth, through the secretion of growth hormone or GH, secreted by the somatotropic cells of the adenohypophysis.This gland is also responsible for the secretion of oxytocin and other hormones in charge of regulating endocrine glandular activity.
Regarding the other options:
Thymus is a gland present in children and related to immune function. Thyroid is responsible for secreting hormones that control basal metabolism. Pancreas has exocrine and endocrine function, producing digestive enzymes and insulin and glucagon, respectively.Answer:

What do you mean by emotive language?Emotive language is the use of descriptive words, often adjectives, that can show the reader how an author or character feels about something, evoke an emotional response from the reader, and persuade the reader of something.
Emotive language refers to language designed to target an emotion – positive, negative, sometimes deliberately neutral – and to make the audience respond on an emotional level to the idea or issue being presented.
Emotive language is an extremely important technique in creating audience engagement with a text. Also called 'loaded language', emotive language occurs when authors choose words extremely carefully to evoke specific emotional responses in a reader.

do oxygen atoms become more stable or less stable when oxygen forms compounds. Explain.
Answer:
Do oxygen atoms become more stable or less stable when oxygen forms compounds? They become more stable because they gain or share valence electrons giving each oxygen atom a set of 8 valence electrons. They change because the number of valence electrons changes in a pattern that repeats in each period.
The air pressure at City A is 1,018 mb, and the air pressure at City B is 980 mb. What will most likely occur due to the pressure gradient present between City A and City B?
Answer:
There are three main causes of change in population: births, deaths and imigration flow. The Coronavirus has affected two of these three factors. The death rate has increased substantially since the pandemic hit. In under 6 months, more than 200,000 people have died. This drastic number of deaths in such a short amount of time is bound to decrease the population of the United States by a considerable margin. Immigration flow has also halted since the beginning of the pandemic. Travel bans and the close monitoring of borders has ensured that the number of immigrants entering the United States has decresed greatly.
Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.
A force exerted on a surface by the air above it as gravity pulls it to Earth is called air pressure or atmospheric pressure. Atmospheric pressure is commonly measured with a barometer.
it determines wind and weather patterns across the globewinds move from high air pressure to low air pressureIt leads directly to wind and influences the speed and direction of that wind.Pressure differences or gradients also affect larger weather systems like storms.Thus, Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.

Explain why there would be more of these organelles.
Answer:
Chloroplasts
Explanation:
You would find more of these in the leaves because they have more surface area. More surface area helps them go through photosynthesis. The leaves also get more light so the chloroplasts are mostly on the leaves so the light can reach them

Both lipids and carbohydrates are important in animal cells because both_____
A. form cell walls
B. provide insulation
C. store energy
D. contain nitrogen
Answer:
Explanation:
C the lipids makes your energy from running out soo soon
Carbohydrates and lipids are essential biomolecules for living. They both helps to store energy. Hence, option C is correct.
What is carbohydrate?Carbohydrates are macromolecules formed from the monomeric units sugars such as glucose, fructose, galactose etc. These monomer molecules polymerise to form carbohydrates such as starch, cellulose, glycogen etc.
Lipids are formed by fat and triglycerols and they they store energy in skin cells. Lipids are important biomolecules because they have significant role in the cell wall formation in plants and cell membrane formation in animals as well as aids for the transport of ions through cells.
Carbohydrates are the main source of energy in animals and plants. It is stored in the form of ATP formed by glycolysis. Hence, both lipids and carbohydrates stores energy.

Insulin lowers the blood-sugar levels in the body.
What are the functions of insulin?Insulin is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the INS gene. It is considered to be the main anabolic hormone of the body.
After you eat, carbohydrates break down into glucose, a sugar that is the body's primary source of energy. Glucose then enters the bloodstream. The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy.
Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism.

A)Revolutions B)Phases C)Rotations D)Eclipses
Answer:
B. phases
Explanation:
The changing shape of the moon in the sky is called phases.
The moon seems to change shape from day to day in a cycle that lasts about a month as it goes through Phases.
How does the Moon's shape seem to alter?
The Moon seems to change shape because we notice distinct amounts of the lit portion as the Moon orbits Earth.
When the Moon is between Earth and the Sun, the lit flank is obscured from us.
As it moves around Earth, the lit flank comes into view. Then it commences and vanishes again.
Thus, The moon seems to change shape from day to day in a cycle that lasts about a month as it goes through Phases.

When does species richness increase at the fastest rate? Why is this possible?
Explanation:
As temperature increases, species richness tends to increase up to a maximum, beyond which water deficits then begin to depress richness
As temperature of the waterbody increases, the species richness tends to increase up to a maximum level, beyond this value water deficits which begins to depress the species richness.
What is Species Richness?Species richness is the number of different species present within a defined region. Species richness is commonly described by an index known as the Shannon's index 'H'.
Temperature has an important influence on the distribution of organisms in an area because it determines the physical state of the water body. Most organisms cannot live in conditions when the temperature remains below 0°C or above 45°C. The organisms cannot adapt to these extreme temperature ranges.
Temperature has been shown to increase the species interactions by increasing attack rate on species.
