Here,
Force = 420N
Gravity = 9.8m/s^2
Mass = ?
Now,
Force = Mass * Gravity
420 = Mass * 9.8
420/9.8 = Mass
Mass = 42.85Kg

Which definition is the best for “semipermeable membrane
Answer: A semi-permeable membrane is that which only allows certain
substances to pass through.
Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.

The equation shows reactants to a neutralization reaction.
Ca2+ + OH– + H+ + NO
Which describes what will happen to the H+ when these reactants form products?
H+ binds with NO to make a salt.
H+ binds with Ca2+ to make an acid.
H+ binds with OH– to make water.
H+ binds with Ca2+ to make a base.
Answer:
Ca²⁺ + OH⁻ + H⁺ + NO₃⁻
Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O
Ca²⁺ + 2OH⁻ + 2H⁺ + 2NO₃⁻ → Ca²⁺ + 2NO₃⁻ + 2H₂O
OH⁻ + H⁺ → H₂O
H⁺ binds with OH⁻ to make water

What environmental condition contributed to the heat wave experienced in Europe and the thousands of deaths in France? a. polluted water b. sewage c. air pollution d. a and b
Answer: c. Air pollution
Explanation:
There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.
Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.

how does secondary succession differ from primary succession? it begins on bare rock or land, it begins where no plants have grown, lichens and mosses form soil first, soil nutrients are already in place
in georgia or in the crib
Answer:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

What are the waste products of alcoholic fermentation?
A. Ethanol and carbon dioxide
B. Lactate and oxygen
C. Glucose and water
D. Carbon dioxide and oxygen
(40 points!!!) (will mark brainliest if its right)
Answer:
ethanol and carbon dioxide :)
Explanation:
The correct option is A. Ethanol and carbon dioxide are the waste products of alcoholic fermentation.
What is alcoholic fermentation?A biological process called alcoholic fermentation, often known as ethanol fermentation, turns sugar into alcohol and carbon dioxide. Alcoholic fermentation is an anaerobic process since yeasts carry out this function and oxygen is not required.
The fermentation process produces heat, carbon dioxide, water, and alcohol as byproducts. In this instance, our attention is on the latter.
A biological process called alcoholic fermentation, often known as ethanol fermentation, turns sugar into alcohol and carbon dioxide. Alcoholic fermentation is an anaerobic process since yeasts carry out this function and oxygen is not required.
