Answer:
SA:V ratio
Explanation:
When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio. When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.

What type of telescope gathers information in almost any weather during any time of the day. The choices are infrared, optical, radio, and x ray telescopes.
Optical should be your best bet.
The telescope that gathers information in almost any weather during any time of the day is optical telescope.
What is an optical telescope used for?An optical telescope gathers and focuses light mainly from the visible part of the electromagnetic spectrum.
Optical telescopes increase the apparent angular size of distant objects as well as their apparent brightness.
Thus, optical telescope is the correct answer.

Greek philosophers such as Democritus and Aristotle had ideas about the composition of matter. For example, Democritus believed matter was made of tiny, solid spheres that he called atomos, and Aristotle thought matter was made of earth, water, fire, and air. Aristotle's idea of matter was the accepted idea for over 2,000 years until John Dalton came up with a new theory about matter based on his experimental data. Which of the following best explains why Dalton’s theory became more widely-accepted over Aristotle's theory?
Aristotle’s theory did not have enough direct evidence due to poor observational tools.
Dalton’s theory had repeated observations which were supported by extensive evidence.
Dalton’s theory was more complete because more respected scientists found the ideas possible.
Aristotle’s theory became the law of conservation of mass when he documented phase changes of matter.
Answer:
The correct answer based on what you provided would be B, or the second answer.
Explanation:
There is evidence in the text to support the answer, and people tend to believe conclusive results over just believing in something, and Dalton's theory was based on results.

It is generally acknowledged that as human beings age, it becomes more difficult for them to lose weight, or even maintain their current weight. People find they have to eat less and/or exercise more to maintain a healthy weight.
Which is the most likely explanation of why weight loss/maintenance becomes more difficult as people age?
a). As humans age, they becomes less active and use their muscles less; therefore, less chemical energy is converted to thermal energy.
b). As humans age, the process of extracting energy from the food becomes less efficient, so more food is needed to provide the same amount of energy.
c). As humans age, they become injured more often and need to increase the amount of food they eat to make repairs to body tissue.
d). As humans age, the body does not convert chemical to thermal energy, so they do no burn off any calories when exercising.

What do osmosis and diffusion have in common?
A.) Both permit molecules of any kind, whether solute or solvent, to cross the bilayer membrane.
B.) Both require the additional energy provided by an energy carrying molecule, like ATP, to allow molecules to pass through the membrane.
C.) Both processes occur through a semipermeable membrane called a concentration gradient.
D.) Both are the net movement of randomly moving molecules that makes concentration nearly equal on both sides of a bilayer membrane.
Answer:
C.) Both processes occur through a semipermeable membrane called a concentration gradient
Explanation:
A. They only let certain things in and out of the membrane
B. They are passive transportors, meaning they do not use ATP or energy
D. They do not randomly move molecules. The concentrations are not equal. It should be from a high concentration to a low concentration.

Which group of plants lacks true roots, stems, and leaves?
A seedless vascular plants
B nonvascular plants
C nonflowering seed plants
D flowering plants
This quetion is from edgenutiy
The nonvascular plants are the group of plants that lacks true roots, stems, and leaves. The correct option is B.
What are non-vascular plants?Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants.
They may instead have more basic tissues with tailored capabilities for the internal transfer of water.
Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.
Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.
The primary distinction between vascular and nonvascular plants is that the former have a vascular system for the transportation of food and water, whilst the latter lack circulatory tissues.
The majority of liverworts are quite rare in the park and need to be close to water to survive. Mosses and liverworts are tiny, non-vascular, primitive plants.
Thus, the correct option is B.
