Answer:
Ions, sugars, amino acids, and sometimes water
Explanation:
Those substances are unable to diffuse across the membrane, so they use an ATP-powered ion pump, channels, and transporters to be transported across the membrane.
Shabbir added an unknown substance to a bottle of water and shook the bottle until the two substances were combined. Then he set the bottle aside for 30 minutes. When he came back, the unknown substance had settled on the bottom of the bottle, and the water had risen to the top. Based on Shabbir’s experiment, what can you tell about the unknown substance? A It is hydrophilic. B It is a type of oil. C It is hydrophobic. D It is a homogeneous solution.
Answer:

How the Law of Conservation of Matter and Energy is conserved during these processes based on the numbers of molecules of the reactants and products?
Explanation:
The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant.
The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
How can recycling impact the environment? A) It uses less energy to make something from recycled materials than from new materials. B) It increases the amount of landfill space needed. C) It uses more natural resources than new materials do. D) It increases the need for mining, creating jobs.
Answer:
A) It uses less energy to make something from recycled materials than from new materials.
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.
Hence, the correct answer is "A)"

Which describes the two ways that energy is measured?
in convection and in temperature
in temperature and in radiation
in radiation and in convection
in wavelength and in temperature
Answer:
The answer is D. In wavelength and temperature
Explanation:
can I have brainiest Please
Energy is the ability to do work, and it is measured in two ways: in temperature and in wavelength. Temperature is a measure of the average kinetic energy of the molecules in a substance, and is typically measured in degrees Celsius or Kelvin.
What is Wavelength?Wavelength, which is commonly expressed in nanometers (nm), is a measurement of the separation between two adjacent points in a wave pattern.
The average kinetic energy of the molecules in a substance is measured by thermometers to determine temperature. This is accomplished by measuring a material's thermal expansion during heating or contraction during cooling.
The molecules have more kinetic energy at higher temperatures. Temperature is an important factor in convection, which is the transfer of heat energy from one place to another through the movement of fluids or gases. Wavelength is measured with spectroscopy, which is the study of the interaction of light with matter.
Spectroscopy is used to measure the wavelength of light, which is the distance between two successive points in a wave pattern. Wavelength is an important factor in radiation, which is the emission of energy in the form of electromagnetic waves. Radiation is the main way that energy is transferred from one place to another in space.

What will be the results in the F2 generation after a monohybrid cross?
all recessive traits
3/4 dominant and 1/4 recessive
all dominate traits
1/3 dominant and 2/3 recessive
Answer: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
Explanation:
Mendel's monohybrid cross is definied as
a genetic combination of two homogeneous genotypes.One is dominant(TT) to other (tt-recessive).Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)
Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)
[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]
The results in the F2 generation after a monohybrid cross: [tex]\dfrac34[/tex] dominants and [tex]\dfrac14[/tex] recessive.
If 10 glucose molecules enter the Krebs Cycle, how many possible molecules of ATP can be produced?
Answer:
20 molecules of ATP
Explanation:
Krebs cycle or also known as Tricarboxylic acid cycle (TCA) is the second stage of aerobic cellular respiration which occurs in the mitochondria. In the kreb cycle, pyruvate, which was synthesized in the first stage of cellular respiration (glycolysis) is broken down into carbon dioxide (CO2).
However, in the krebs cycle, two (2) ATP molecules is produced per glucose molecule that enters cellular respiration. Hence, according to this question, If 10 glucose molecules enter the Krebs cycle, (2 × 10) = 20ATP molecules will be possibly produced.
Answer:
20 molecules of ATP

The cover of high-elevation clouds in 2002 was
closest to which of the following?
A. 5.5 okta
B. 4.0 okta
C. 3.0 okta
D. 2.5 okta
Answer:
B. 4.0 Okta
Explanation:
Okta is a measurement of cloud elevation in metrology. NASA used this metric to identify the cloud elevation. The cloud elevation reached to 4.0 okta during the year 2002. High elevation ecosystem is vulnerable. The change in okta does not produces new substance and the elevation of cloud is changed.
High elevations clouds are located at a height of 20,000 feet. They are high above where the temperature is very low and are composed of ice crystals and appears white.
The correct answer is:
Option B. 4.0 Okta
This can be explained as:
A unit of measurement of cloud extension is called okta. The amount of cloud cover at a given place in meteorology can be defined by okta.This is widely used by the meteorology department of NASA.During 2002, the elevation of clouds reached 4.0 okta.This high value of okta can make the ecosystem vulnerable.The elevation in okta value does not affect the production of any new substance.Therefore, the value was 4.0 okta in 2002.

As the moon revolves around Earth, it appears to change shape. The moon goes through phases during a period that lasts about one month. Describe what causes the moon to change shape as it goes from a full moon to a last-quarter moon.
Answer:
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
Explanation:
The moon appears to change its shape during the revolving around the earth. This change in the shape of the moon takes place due to the fact that the moon does not have its own light and it reflects light from back to us on the earth.
The moon changes its shape on the basis of how much-reflected light or moon we can see and how much of the moon is facing the sun.
The correct answer is - the reflected light of sunlight changes as it moves around the earth.
A scientist performs an experiment to see how plants respond to acid rain. He places the water plants in water of varying pH measurements. The pH levels are 2.5, 6.0, 7.0, and 9.0. Each day, he measures the health of the plants by counting the number of leaves on the plant. The plants used in this experiment typically grow in water at a neutral pH.
Why was only one variable tested in this experiment?
The scientist tested one variable to determine what caused the number of leaves to change.
It just happened that way; you can test as many variables as you want.
The scientist ran out of materials so he tested only one variable.
The scientist tested two variables.
Answer:
The scientist tested one variable to determine what caused the number of leaves to change.
