a
Mountain frogs in low-altitude habitats only
b
Mountain frogs in their natural high-altitude habitat
c
Mountain frogs in a lab setting exposed to UV rays from a sun lamp
d
Mountain frogs in a lab setting with no UV ray exposure
Answer:
c
Explanation:
if the scientist was to look close there skin would be tightened up on the frog it is hard to see but if you look close you could see it
Answer:
C or D I think
Explanation:
D, you could compare frogs with no UV ray exposure to the ones with UV ray exposure
C, you can do the same but reverse
Edit: Meaning of control group is "A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results."
So its more likely to be D

Which describes electrons?
A.) Electrons move at very fast speeds inside the nucleus of an atom.
B.) Electrons are stationary outside of the nucleus of an atom.
C.) Electrons are stationary inside the nucleus of an atom.
D.) Electrons move at very fast speeds around the nucleus of an atom.
The answer is D.) Electrons move at very fast speeds around the nucleus of an atom.
The option that best describes electrons is as follows:
Electrons move at very fast speeds around the nucleus of an atom.Thus, the correct option is D.
What is Electron?An Electron may be defined as a negatively charged subatomic particle that is significantly found in all atoms and functions as a primary carrier of electricity mostly in solids.
The electrons are always revolving around the nucleus of an atom, while protons and neutrons are localized in the center of an atom known as the nucleus.
Electrons are negatively charged subatomic particles and due to this, they generate an electric field that exerts an attractive force on a particle with a net positive charge and induces a repulsion force on a particle with the same negative charge.
Therefore, the option that describes the electrons is that they move at very fast speeds around the nucleus of an atom. Thus, the correct option for this question is D.

A 68-year-old woman who presents after a fall reports progressive difficulty climbing stairs for the past 3 months. She also feels a loss balance when rising from a chair. She has a 5-year history of diabetes mellitus for which she takes metformin. Examination demonstrates intact cranial nerve function; normal sensory examination except for mildly decreased touch and vibration in her toes, normal motor function except for 4+/5 deltoid power and 4+/5 hip power bilaterally, and an inability to stand on her toes. Deep tendon reflexes are 2+ but 1+ at the ankles; plantar responses are flexor; cerebellar function is normal except for mild difficulty with heel-knee-shin testing. She has difficulty rising from a chair without pushing up with her hands. These clinical findings are best explained by dysfunction in which of the following regions of the nervous system?A. anterior horn cellB. muscleC. nerve plexusD. peripheral nerveE. spinal cord
Answer:
spinal cord and nerve plexus
Explanation:
Faced with this clinical picture, we would be talking about the affection of the spinal cord and the peripheral nerves that sensually perceive the areas of the epithelium, that is, they give the sense of touch, since the patient is diabetic, it could be deduced that the microangiopathies that this generates Chronic disease over time, can affect the irrigation of certain areas and therefore their inventions, due to lack of supply of oxygen and nutrients.
Diabetics are at risk of affecting both upper and lower limbs, because over time they lose the vascularization and winterization of these areas, thus generating infections or pain imperceptible by the patient.
On the other hand then, it would be ideal to say that the spinal cord with the peripheral nerves that innervate the affected areas, and the cerebellum are affected by the lack of balance or spatial disposition of the patient in relation to their body size.

A solution with a pH of 2 can be increased to a pH above 7 by adding
Answer:
an acid
Explanation:
A solution with a pH of 2 can be increased to a pH above 7 by adding base (e.g. sodium hydroxide, potassium hydroxide).
What is a base?Bases are chemical substances that have a pH higher than 7 and that can neutralize acids. They have properties such as a bitter taste, slippery feel, and the ability to turn red litmus paper blue. Bases are classified as either strong or weak, depending on their ionization in solution. Strong bases have a high degree of ionization and can rapidly neutralize acids, while weak bases ionize to a lesser extent and have a slower effect on the pH of a solution.
Bases are important in many industrial and biological processes, and are used in cleaning agents, fertilizers, and medicines. The most well-known base is probably sodium hydroxide, commonly known as lye, which is used in the manufacture of soaps, detergents, and other products. Understanding the properties and behavior of bases is important in many fields, including chemistry, medicine, and environmental science.

can somebody help me make a claim , evidence and reasoning on “Do you think school days should be made longer?
i need it now please help me
Answer:
i don't think so school days must be shorter and practical session must be longer theory is boring
Answer:
I think school days should not be made longer as this would impact the students mental health. Students attend school for approximately 7 hours a day in which they learn new content, this time being increased would cause stress and burden on students as classes would be longer and time spent at home would be less. Students need enough time to rest and relax their minds, as well as, spend time with their families. If extending school hours, students will have less time for self-care and family time which can lead to depression and loneliness. However, there are benefits of extending school hours such as more time to finish homework. But, a student's health must come first. In conclusions, school days should not be made longer.

Answer:
f = 7.87×10¹⁴ Hz
Explanation:
Given data:
Speed of light = 3×10⁸ m/s
Wavelength of light = 3.81 ×10⁻⁷ m
Frequency of light = ?
Solution:
Formula:
Speed of wave = wavelength × frequency
Now we will put the values in formula.
3×10⁸ m/s = 3.81 ×10⁻⁷ m × f
f = 3×10⁸ m/s / 3.81 ×10⁻⁷ m
f = 0.787 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.787 ×10¹⁵ Hz
f = 7.87×10¹⁴ Hz

Which equation best represents conservation of matter?
A 6H2O + 6CO2 → C6H12O6 + 6O2
B 6H2O + 6CO2 → C3H6O3 + 3O2
C 3H2O + 3CO2 → C6H12O6 + 6O2
D 6H2O + 10CO2 → C6H12O6 + 4O2
Answer:
A 6H2O + 6CO2 → C6H12O6 + 6O2
Explanation:
The law of conservation of matter states that matter can neither be created nor destroyed in a system. In other words, when elemental matter undergoes a reaction, the amount of elements used must be equal the amount produced.
The equations in this question depicts the overall photosynthetic process where CO2 combines with H2O to produce C6H12O6 and O2. In order for this equation to obey the "conservation of matter", each individual element must be equal on both the reactant and the product side i.e. the equation must be balanced.
The equation that fulfills this is:
6H2O + 6CO2 → C6H12O6 + 6O2
Hence, it correctly describes the conservation of matter.

What type of protist is an amoeba and how does it move?
Answer:
Explanation:
An amoeba is a classification of protist (single-celled eukaryotic organism that is neither plant, animal, bacteria, nor fungus) that are amorphous in shape. They move via forming 'feet-like' pseudopodia, which are also used for feeding.
Answer:
Explanation: Amoeba and sarcodines are examples of protists that move by pseudopods. Some animal-like protists move by using cilia. Cilia are hair-like projections that move with a wave-like pattern. The cilia move like tiny oars to sweep food toward the organism or to move the organism through water.
