In which of the following situations does the cell use active transport?
Answer: The correct option is B. Sodium ions move into the cell from areas of lower concentrations.
Explanation:
Active transport can be described as a process in which molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Energy is required for the process of active transport to occur.In the option B, sodium ions are moving into the cell from areas which have a low concentration of sodium i.e against the concentration gradient. Hence, option B tells that the sodium ions will move inside the cell by the process of active transport.

This functional group consists
of three hydrogen atoms
bonded to one carbon atom. HaC-
Which functional group is
shown in this image?
A. an amino group
B. a methyl group
C. a phosphate group
D. a carbonyl group
Answer:
B.) a methyl group
Explanation:
A.) is incorrect because an amino group has a central nitrogen atom bonded to two hydrogen atoms.
B.) is correct because methyl groups consist of one central carbon bonded to three hydrogen atoms.
C.) is incorrect because a phosphate group contains a phosphorus central atom and four surrounding oxygen atoms. It should be noted that one of the oxygens is double bonded to the phosphorus, while the other three oxygens are single bonded to the phosphorus.
D.) is incorrect because carbonyl groups consist of a central carbon atom double bonded to an oxygen atoms. The carbon is also bonded to two R groups (normally some type of carbon chain).

give two effects of photolysis of water during light-dependant reaction
Spliting of water and production of oxygen are the two effects of photolysis of water during light-dependant reaction.
What are the effects of photolysis of water during light-dependant reaction?Photolysis refers to the use of light energy in order to split water molecules and produce oxygen. In the light-dependent reactions, light energy is absorbed by chlorophyll and transferred to the reaction center of photosystem II.
So we can conclude that Spliting of water and production of oxygen are the two effects of photolysis of water during light-dependant reaction

Habituation is defined as a decrement in response as a result of repeated stimulation not due to peripheral processes like receptor adaptation or muscular fatigue. It is a process occurring within the nervous system (in animals with nervous systems).
An investigation involving osmosis and plant cells was performed by a group of students. Sweet potatoes were used as
the source of plant cells in the experiment. A sweet potato was diced into evenly sized andshaped cubes and placed
in beakers containing various glucose concentrations. The experimental setup is shown in the table here.
Which statements accurately predict the beaker in which water will enter the cells at a greater rate, causing an
Increase in mass for the sweet potato cells?
A)
Beaker 1
B)
Beaker 3
C) beaker 4
Answer:
A
Explanation:
Water will enter and leave the cells at the same rate via osmosis
The correct option is (A) Beaker 1 in which water will enter the cells at a greater rate, causing an increase in mass for the sweet potato cells.
What is Osmosis?Osmosis refers to a process in which the water or solvent diffuse across a semipermeable membrane (here cell membrane) from the area of high solute (here glucose) concentration to low solute concentration. The concentration of glucose in the water of beaker 1 is 1.5M which is highest as compared to other beakers.
The concentration of glucose solution in beaker 1 is hypertonic to the concentration of glucose in the cell which makes the water to move inside the cell via osmosis. Movement of water inside the cell results in increase in mass for the (sweet potato) cells.
Thus, the water will enter the cells at a greater rate in the beaker 1 because the glucose concentration is highest in the beaker 1 corresponding to its cell glucose concentration.

Expalin the physiological concepts associated with muscular tissue at a microscopic level
Answer:
Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity. Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity.
Explanation:
Muscle tissue has four distinct properties: excitability, contractility, extensibility, and elasticity.
What are muscles?The human body contains approximately 600 muscles. Skeletal, smooth, and cardiac muscles are the three primary types of muscle.
The neuromuscular system is the collaboration of the brain, nerves, and skeletal muscles to end up causing mobility.
Muscle fibers are highly specialized cells that make up the muscular system. Their main function is contractility.
Movement is governed by muscles, which are attached to bones or vital organs and blood vessels. Muscle contraction causes nearly all movement in the body.
Muscle tissue is distinguished by characteristics that enable movement. Muscle cells are excitable, meaning they respond to stimuli.
They are contractile, which means they can simplify and produce a pulling force. When muscles are attached between two movable objects, such as two bones, they contract.
Thus, these are the three physiological concepts associated with muscular tissues.

Images shows a lake labeled carbonates in water, a cow labeled animal respiration, a tree labeled photosynthesis, a factory labeled factory emissions, the sun labeled sunlight, a cloud labeled carbon dioxide in atmosphere, another tree labeled plant respiration, an arrow from organic carbon to dead organism, and fossils and fossil fuels. Arrows are labeled as follows: A from the sunlight to photosynthesis, B from carbon dioxide in atmosphere to photosynthesis, C from factory emissions to carbon dioxide in atmosphere, D from carbon dioxide in atmosphere to carbonates in water, E from dead organisms to fossils and fossil fuels, and F from plant respiration to the sky.
Using the diagram above, answer the following questions:
6. True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
7. True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
8. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
9. Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
From factory emissions to carbon dioxide in the atmosphere (C)
The process occurring can be called Combustion. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because the carbon in organic matter is oxidized to form CO2.
from dead organisms to fossils and fossil fuels (E)
The process explained in the question can be stated as Fossilisation. In this process, dead remains of plants and animals are transformed into fossils under pressure. The organic matter is preserved according to the shape of the organism.
from factory emissions to carbon dioxide in the atmosphere (C) & from carbon dioxide in the atmosphere to photosynthesis (B)
Two reactions represent the conversation of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure
