what surfaces or objects on earth would reflect infrared light well?
Answer:
Infrared, sometimes called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye.
Aside from water vapor, bodies of water on the surface of the Earth also absorb IR wavelengths well. Glass, wood, brick, stone, asphalt and paper all absorb IR radiation. While regular silver-backed mirrors reflect visible light waves, allowing you to see your reflection, they absorb infrared radiation.

This type of energy is not always predictable.
Answer:
Wind energy.
Explanation:
In this way, the biggest shortcoming of wind energy, which is that it is not always stable and predictable, is solved by the new technology. It goes without saying that this impressive and innovative combination of wind as a renewable energy source and the power of water as storage energy has a lot to offer in the energy production field.

which statement correctly describes greenhouse gases in the atmosphere?
Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.
What are stem cells? How are embryonic stem cells different from adult stem cells?
Answer:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated.
Embryonic stem cells are derived during early development at the blastocyst stage and are pluripotent, meaning that they can differentiate into any cell type. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

Which of the following correctly defines one of the four parts of natural selection?
a
variation: the difference in the heritable traits of an individual from those of other individuals in the same species or population
b
extinction: the state in which all of the members of a species have died
c
overproduction: the process by which each generation produces more offspring than the previous generation produced
d
adaptation: an acquired trait that lets an organism better survive in its environment
Answer:
a- variation
Explanation:
Answer:
A
Explanation:
correct option A- variation
Which explanation describes how natural selection produces changes in organisms?
Natural selection enables a trait of an individual to be expressed.
Natural selection occurs when a favorable phenotype allows for differential reproductive success in a population of organisms.
Natural selection occurs when individuals that develop disease die.
Natural selection occurs when neutral phenotypes become common in a population in
Answer: B. Natural selection occurs when a favorable phenotype allows for differential reproductive success in a population of organisms.

HELP WILL GIVE BRAINLY!! The dominant allele is not completely expressed when the recessive allele is present.
A.Complete Dominance
B. Codominance
C. Incomplete dominance
D. Polygenenic
Answer:
I will give you an explanation, and try to figure it out!!
Explanation:
Incomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. This results in a phenotype that is different from both the dominant and recessive alleles, and appears to be a mixture of both.

which laboratory tools are useful when looking at internal organs of an earthworm
Answer:
An earthworm's internal organs can be viewed through a dissecting microscope. This type of microscope allows enhanced observation of objects that are too large for a compound microscope. Because the magnification is low, this microscope cannot be used to examine cells.

Answer:
pa heart follow back follow me brainliest me please
Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.
