Distinguish between natural selection and artificial selection.
Answer: Natural selection is based on the adaptive characteristics of animals. Artificial selection is based on the desirable characters selected by humans. Only beneficial or favorable traits are inherited over the successive generations by natural selection. Natural selection is performed on all the types organisms; Artificial selection is processed on some selective organisms of humans desires. ... Natural selection results in the transformation of the entire population of a species; Artificial selection brings out the new variety of that species.
Explanation:
Answer:
answer in explanation
Explanation:
Natural selection occurs over a long period of time and happens naturally. artificial selection happens relatively fast and occurs when humans choose a certain trait they like and help the animal with that trait reproduce.
explain why the blood of an insect does not contain respiratory pigments
Answer:
Explanation: Respiratory pigments like haemoglobin, haemocyani, are needed for transport of respiratory gasses. In insects there is no such pigment in blood, because oxygen is directly delivered to cells by trachea!

As the lock for the door opens you enter another room. This one has plain cement walls with huge silver and copper pipes running from floor to ceiling. The room reminds you of a basement mechanical room even though you have just gone upstairs. Everywhere there are old wooden crates and piles of gears of all sizes, springs, gages and the hands of old clocks. As you gaze around the door you just entered closes and will not open. (and even if it would you are not sure of what has happened to the Antique Dealer and maybe there is some danger that way.) Someone in the group checks their phone but there'is no signal. Maybe all this cement and metal is blocking your signal. Next to another door is an interesting framed collage made of miscellaneous gears and pieces.
A safe room can be the difference between life and death during a home invasion. While a home security system is extremely important for immediately contacting law enforcement, a safe place for anyone inside to wait for the police is necessary. It can always be a great place to store valuables that you do not regularly use, like having
What is the period of a wave if the wavelength is 100 m and the speed is 200 m/s?
O 0.5 s
o 25
100 s
200.000 s
Answer: 0.5 s
Explanation: speed = wavelength · frequency and period T = 1/ frequency.
Frequency = speed / wavelength = 200 m/s : 100 m = 2 s^-1 and T = 0.5 s

name the living matter of the cell.
Cellular respiration begins with Glycolysis, in which an investment of 2 ATPs are needed in order to break a carbon-carbon bond in 1 glucose molecule. When the bond is broken, high energy electrons are released and carried by ___________ to go to the Electron Transport Chain. The resulting carbon compound, pyruvate, will enter the Krebs Cycle. A net gain of 2 ATP are created. However, if oxygen is not readily available to the cell (and the mitochondria), ____________ and pyruvate will enter Lactic Acid Fermentation to free up the ____________ so it can continue accepting high energy electrons from the breakdown of glucose in Glycolysis. This will, in turn, continue to create a small, but steady supply of ATP energy.
Answer:
1. NADH
2. NADH
3. NADH
Explanation:
Cellular respiration begins with Glycolysis, in which an investment of 2 ATPs are needed in order to break a carbon-carbon bond in 1 glucose molecule. When the bond is broken, high energy electrons are released and carried by NADH to go to the Electron Transport Chain. The resulting carbon compound, pyruvate, will enter the Krebs Cycle (to produce GTP/ATP as well as NADH and FADH₂ which carries electrons to the electron tranport chain). A net gain of 2 ATP are created. However, if oxygen is not readily available to the cell (and the mitochondria), NADH and pyruvate will enter Lactic Acid Fermentation to free up the NADH so it can continue accepting high energy electrons from the breakdown of glucose in Glycolysis. This will, in turn, continue to create a small, but steady supply of ATP energy which is the 2 ATP generated in the payoff phase of glycolsis.

which statement best describes a cause and its effect during the process or muscle contraction?
Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.

Name and give examples of 2 major types of mutations. What do they have in common? How are they different?
Answer:
The correct answer would be - Two major types of mutations are deletions and substitutions.
Explanation:
The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.
The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.
Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.
Compare marshes, swamps, and bogs.
Answer:
Marshes: Have extremely good ability to support grasses, reeds, flowers, and insects due to their high nutrient soil. They usually are around lakes/rivers/and other bodies of water. They are frequently covered in water however not always covered in water.
Swamps: Have extremely good ability to support wood like plants, trees. They are also permanently covered/submerged in water all year around.
Bogs: Basically they are a gravesite of a dead plant life. When a lake fails to support itself it turns into a bog, its plant life dies off and will start rising to the top creating almost a film. However even though the plant life dies the insects, reptiles, and Amphibians thrive.

Explanation:
Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
Answer:
The type of mutation that causes this translation error is called deletion. Deletion occurs when a section of a DNA is deleted or lost. In cystic fibrosis, three nucleotides are deleted that results in the lost of phenylalanine

why is it important to classify the millions of species on earth
There are millions of species that exist on Earth. This helps in organizing each specie according to the characteristics, and traits. The classification is done to show the hierarchy and focuses on the relationships that the organisms possess with other organisms about evolution.
Because stress is a force, it... A) takes energy out of rock B) adds energy to rock C) adds volume to rock. D) makes rock harder.
Answer:
it adds energy to the rock
Explanation:
Because stress is a force, it adds energy to the rock. This stress/force is being applied to the rock. Whether the rock moves or not you are applying a force to the rock and it has potential energy. If the rock moves, you are adding energy to it and creating kinetic energy as the rock moves. Other forces such as gravity and friction can push against your force and prevent the rock from moving. Therefore, there are many forces at play in such a scenario.

Answer: 5188965.565
Explanation:
Forensic scientists have been called by police to come to a home. There is a dead body in the living room, which has been found by the victim's dog walker when she entered the home through the back door. The front door was shut and locked, and there is no sign of other forced entry. The dog walker states that a vase is missing from the living room. What would be the best question for the forensic scientists to ask in this situation?
Where is the missing vase?
How did the victim die?
How did the robber get in the house?
Did the dog walker steal the vase?
Answer:
I think it might be how did the victim die because they might have died of a heart attack or something normal. Then they can start asking where the vase went.
