Answer:
THERMOSPHERE
Explanation:
The layer of the atmosphere that contains the ionosphere is the thermosphere.
The thermosphere is the uppermost layer of the Earth's atmosphere, located above the mesosphere and below the exosphere. It extends from an altitude of about 80 kilometers (50 miles) and extends upward into space.
The thermosphere is known for its extremely high temperatures, reaching up to thousands of degrees Celsius, despite having very low air density. The ionosphere is a region within the thermosphere where the molecules and atoms are ionized due to high-energy solar radiation.

As glucose and other biomolecules are broken down by aerobic respiration, the cell’s chemical reactions capture as much energy as possible into a few molecules of ATP and many molecules of 2 electron energy carrier molecules called what?
Answer:
NAD - nicotinamide adenine dinucleotide
FAD - flavin adenine dinucleotide
Basically, NAD and FAD carry electrons to the electron transport chain in the inner mitochondrial membrane. These electrons are deposited near the beginning of the electron chain, and then these electrons are passed on from one protein to the next.
As these electrons move through the electron chain, they release energy, and some of this energy is captured in the form of an electrochemical gradient and used to make ATP.
Energy contained in the bonds of glucose is released in small bursts, and some of it can be captured in the form of ATP, a small molecule that is used to power reactions in the cell.
ATP = adenosine triphosphate
Answer:
I think it might be nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD).
Hello! What are some differences and similarities in Gymnosperms and angiosperms?
Answer:
there both seed bearing plants there from the kingdom plantae ,and there vascular plants
Explanation:
Answer:
Similarities:
- They share a main plant body: diploid sporophyte.
- The sporophyte, in both groups, is separated into the root, stem, and leaves.
- They are both two major Seed Plant groups
- Vascular bundles, the strand of vessels in a plants stem or leaves, are conjoined, open, and collateral.
Differences:
- Gymno are mostly trees and they do not produce flowers, while Angio can be herbs or shrubs, and produce flowers as well.
- Gymno plants are evergreens and Angios are seasonal
- The leaves of a Gymno are thick and need like while Angio leaves are flat
- The wood of a Gymno is soft-like while an Angio has hard wood.

The total amount of kinetic energy molecules in the environment in a given area decides the hotness and coldness of the temperature. The correct option is C.
What is kinetic energy ?The energy possessed by the moving molecules is called as kinetic energy and the energy which possesses the motion of a body is the kinetic energy.
Temperature is the factor where the total measurements of the environmental factors are decided as well.
The amount of air mass that is present in the area whether they will form rain, clouds or precipitation is decided on the basis of the environmental factors and the energy possessed by the molecules.
Therefore, The measurement of the energy in molecules of air in a given area is given by temperature.

Unlike the other big moons like Ganymede, Titan, Europa, Callisto and Triton, our Moon lacks any real atmosphere and isn't covered in ice. Sure, it is a lot closer to the Sun, so maybe it lost much of its ice (there is some), but it is a much more desolate locale compared to the icy moons of the solar system

Which statement correctly describes energy transfer in ecological pyramids?
A: 90% of energy available go to the next level B: hundred% of the energy will go to the next level. C: 50% of the energy available will go to the next level. D: 10% of the energy available go to the next level
Answer:
4
Explanation:
The statement that correctly describes energy transfer in ecological pyramids is 10% of the energy available go to the next level.
How is energy transferred in ecosystem?In an ecosystem, living organisms feed on one another to derive energy needed for their metabolism.
However, only 10% of the energy is transferred to the next trophic level as 90% of this energy is used for the metabolic activities of the organism.
Therefore, the statement that correctly describes energy transfer in ecological pyramids is 10% of the energy available go to the next level.

How can PCR and gel electrophoresis be used to identify people?
Answer: answer
Explanation: Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
PCR can be used to amplify short fragments of DNA, while gel electrophoresis can be used to determine how large these DNA fragments in a given sample are.
The Polymerase chain reaction (PCR) is a widely used methodology in molecular biology in order to amplify short fragments of DNA (about 1000 base pairs) from a given sample.
The order of nucleotides in the DNA molecule is specific to each individual, thereby the amplification of regions showing sequence polymorphisms can result very useful in order to identify individuals, populations, species, etc.
The DNA regions showing polymorphisms between nucleotide sequences are known as molecular markers.
For example, microsatellites are specific nucleotide sequences (i.e. loci) that serve as molecular markers because they exhibit differences in length among individuals.
In consequence, PCR amplification and subsequent separation in an electrophoresis gel enable the identification of individuals by comparing DNA samples.
In conclusion, PCR can be used to amplify short fragments of DNA, while gel electrophoresis can be used to determine how large these DNA fragments in a given sample are.

1) A. Grasses ---> Flowering Plants ---> Shrubs ---> Native trees
2) A. Ecological succession helps maintain equilibrium in an ecosystem
3) B. Primary succession
4. B. There are more pioneer species in secondary succession.
The sequence of ecological succession.
The ecological succession is a process by which the mix of species in the habitat or the area changes as per time. The sources get evolved and others die out. The mature forest reaches its climax and hence gets destroyed by the factors of the environment and many other stages.
Thus the answer is grasses→ flowering plants → shrubs → native trees, succession helps maintain equilibrium, primary succession, more pioneer.
As per the question, the sequences of the ecological succession that takes place in an abandoned wheat field are that of Grasses to Flowering Plants to Shrubs and to the Native trees.The relation is between the ecological succession and equilibrium of species is that of helper that maintains the ecosystem.,The Primary succession appears on the small plants that rapidly develop on new lands. The secondary succession is faster than the first as more pioneer species are in the succession.Hence option A, A, B, and B is correct.
