Answer:
Natural selection or "survival of the fittest"
Explanation:
Creatures that adapt to survive changes will live to reproduce, while the creatures that do not adapt will die out.
Darwin states that evolution happens to natural selection, which is the concept that creatures tend to adapt to their environment.

DNA sequencing by the chain-termination method utilizes DNA polymerase I to make a complementary copy of the target or template DNA molecule. A reaction with a 20 bp template and dideoxyadenosine nucleotides as terminators results in the production of a 5 bp fragment. Based on this result, we can conclude that the template contains A) a cytosine at position 5. B) a thymine at position 5. C) a cytosine at position 16. D) a thymine at position 16
Answer:
D) a thymine at position 16
Explanation:
The chain termination method (Sanger sequencing), is a sequencing technique used to determine the nucleotide sequence of a specific fragment of DNA. The classical method has three steps: 1- the target DNA fragment to be sequenced is used as a template for chain-termination PCR technique where modified deoxyribonucleotides (ddNTPs) are added to the PCR reactions to be incorporated by the DNA polymerase during in vitro DNA replication, 2-the DNA fragments of different sizes are separated by electrophoresis, and 3-determination of the DNA sequence by observing the identity of the terminal ddNTP in each band of the electrophoresis gel. For example, if the bottom band in the electrophoresis gel colocalizes in the column with ddATP as terminator, then this fragment finishes with ddATP, which means that the last nucleotide from the 5' end is Adenine.

A gardener plants 200 flowering plants of the same species. 98 plants have white (v) flowers and the remaining have violet (V) flowers. What must be the allelic frequency of each type of flower? ( p + q = 1, p2 + 2pq + q2 = 1)
A.
violet flowers = 0.55, white flowers = 0.45
B.
violet flowers = 0.62, white flowers = 0.38
C.
violet flowers = 0.3, white flowers = 0.7
D.
violet flowers = 0.49, white flowers = 0.61
The allelic frequency of each type of flower is violet flowers = 0.3, white flowers = 0.7, option C.
What is allelic frequency?The incidence of a gene variant in a population is represented by the allele frequency. The number of times the allele of interest is observed in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to calculate the allele frequency and can be expressed as a decimal, a percentage, or a fraction.
To find the allele frequency:
Frequency = 98/200 = p = 0.49 for white (v) flowers
VV - dominant homozygote with violet flowers and with frequency p²
Vv - heterozygote with violet flowers and with frequency 2pq
vv - recessive homozygote with white flowers and with frequency q²
q² = 0.49 = √q² = √0.49 = 0.7
Therefore q in the formula p + q = 1, = p + 0.7 = 1
p = 1 - 0.7 = 0.3
The frequency for violet flowers, p is 0.3 and white flowers, q is 0.7 with substitution method of the "p + q = 1, p2 + 2pq + q2 = 1" formula.

PLEASE ILL LITERALLY DO ANYTHING You have learned that the human body is made of different systems. These systems work together to help the body function. In this project, you will research how different body systems interact. OBJECTIVES Describe the interaction between human body systems. Directions Use online resources or a reference of your choosing to research two body systems from the list below. Write a 400 word essay describing each system and how they interact. Be sure to include the major organs and structures of each system. Also identify the functions and responsibilities of each system. Describe how each system depends upon the other. circulatory system respiratory system digestive system excretory system nervous system
Answer:
The Circulatory system has two organs the heart, and blood vessels. The heart pumps blood and the blood is carried away and back through blood vessels like capillaries, veins, and arteries. The Circulatory system works with the Respiratory system by carrying the oxygen that is brings in, and takes away the carbon dioxide to the Excretory system. The Circulatory system helps the Excretory system by bringing waste, and carbon dioxide to kidneys, and liver I believe it might be a different organ but I know the kidneys for sure.
The Nervous system consists of three organs the spinal cord, brain, and nerves. The two systems are the Central Nervous system is made up of the the brain, and spinal cord. The Peripheral system is made up of the nerves, which branch off from the spinal cord to all parts of the body. The Central Nervous system sends a jolt of electricity from the brain through the spinal cord to the nerves that branch of it to all parts of the body so that we can move. The Nervous system helps the Digestive system by sending electricity to the nerves so that we can swallow our food and so that we can digest our food. The Nervous system helps the Excretory system by detecting any changes in the salt levels in the blood through the urine in the Excretory system. By providing the brain with a constant supply of oxygen rich blood the Circulatory system helps the Nervous system, so the Nervous system regulates the heart rate and blood pressure. So that the Nervous system can regulate the Respiratory rate, and monitor the blood gas levels the Respiratory system supplies oxygen, and removes carbon dioxide.
The Excretory system consists of five organs the Large Intestine, Liver, Lungs, Kidneys, Skin. The Excretory system helps the Digestive system by getting rid of the waste it produces. The circulatory system helps the Excretory system by giving the kidneys, and the other organs in the Excretory system blood, and carry carbon dioxide from cells to the kidneys.
The Respiratory consists of five organs Lungs, Larynx, Trachea, Pharynx, and Bronchi. The Respiratory system provides the body with oxygen, and allows us to breath.
The Digestive System consists of nine organs, the Mouth, Esophagus, Stomach, Pancreas, Liver, Gallbladder, Small Intestine, Large Intestine, and the Anus. The Digestive system dissolves food and turns them into nutrients for cells, to give them energy, use for growth, and cell repair.

the three laws of motion
Answer:
The Newton's three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion.
Explanation:
Answer: Hope This Helps!
Explanation:
Newton's First Law of Motion:
Newton's First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it. Similarly, if the object is at rest, it will remain at rest unless an unbalanced force acts upon it. Newton's First Law of Motion is also known as the Law of Inertia.
Basically, what Newton's First Law is saying is that objects behave predictably. If a ball is sitting on your table, it isn't going to start rolling or fall off the table unless a force acts upon it to cause it to do so. Moving objects don't change their direction unless a force causes them to move from their path.
As you know, if you slide a block across a table, it eventually stops rather than continuing on forever. This is because the frictional force opposes the continued movement. If you threw a ball out in space, there is much less resistance, so the ball would continue onward for a much greater distance.
Newton's Second Law of Motion:
Newton's Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will need to be to cause it to accelerate. This Law may be written as force = mass x acceleration or:
F = m * a
Another way to state the Second Law is to say it takes more force to move a heavy object than it does to move a light object. Simple, right? The law also explains deceleration or slowing down. You can think of deceleration as acceleration with a negative sign on it. For example, a ball rolling down a hill moves faster or accelerates as gravity acts on it in the same direction as the motion (acceleration is positive). If a ball is rolled up a hill, the force of gravity acts on it in the opposite direction of the motion (acceleration is negative or the ball decelerates).
Newton's Third Law of Motion:
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.
What this means is that pushing on an object causes that object to push back against you, the exact same amount, but in the opposite direction. For example, when you are standing on the ground, you are pushing down on the Earth with the same magnitude of force that it is pushing back up at you.

GRB2 is the protein that links RTK signaling to integrins and focal adhesions. More precisely, focal adhesions sequester GRB2, removing it from the cytoplasm, and thus preventing it from transducing the signal from the RTK to Ras. Based on this information, say something meaningful about focal adhesions, namely something about the domain structure of one of the proteins within them.
Answer:
It transmit mechanical force and signals.
Explanation:
Focal adhesions are large macromolecular which is responsible for the transmission of mechanical force and regulatory signals between the extracellular matrix and an interacting cell. Focal adhesions act as the mechanical linkages to the ECM, and serves as a biochemical signaling hub to direct numerous signaling proteins at sites of integrin binding and clustering. 68-kD protein also known as paxillin is a type of protein which is part of cytoskeletal component that localizes to the focal adhesions.

Next week produces a heat wave in Prince George's County. Most scientists would say:
A. Global warming is the cause
B. Human activity is the cause
C. Local temperatures over one week tell us more about weather than climate
D. Our climate is getting warmer
Answer:
A. Global warming is the cause
Explanation:
Our climate is getting warmer due to production of heat wave because the heat wave has high temperature which increases the temperature of the surrounding environment. Researchers found that as global temperatures increase, heat waves will become more frequent and the time between them will become shorter and we know that global temperature increase due to global warming so we can say that global warming is the cause of more heat wave.

Clouds are formed when water vapor in the air condenses to form liquid water or ice. So, the correct option is D.
What are Clouds?Tiny water droplets or ice crystals in the Earth's atmosphere can be seen as visible collections in the form of clouds. They form when moist, warm air rises and cools, causing water vapor in the air to condense into tiny droplets of water or ice. Clouds are formed when water vapor in the air condenses to form liquid water or ice.
As warm, moist air rises and cools, water vapor in the air condenses around fine particles such as dust or salt to form droplets or ice crystals. The ice crystals or droplets then group together to form clouds. The water cycle, which works to move water and energy across Earth's atmosphere and surface, is crucial to the process of cloud formation.
Therefore, the correct option is D.

Explanation:
Suppose we have a disease phenotype that is determined by a single gene with two alleles. Further suppose it follows a autosomal recessive mode of inheritance with reduced penetrance. We have an individual who is unaffected (does not have the disease phenotype) and whose genotype is unknown. We cross this individual with a true-breeding affected individual. How many possible genotypes can this unaffected individual have at the disease locus
Answer:
three (3)
Explanation:
Penetrance can be defined as the proportion of individuals that have mutations associated with a genetic disorder and exhibit symptoms of having that genetic disorder. Moreover, reduced penetrance, also known as incomplete penetrance, indicates that an individual who carries mutations for a disorder but may never develop this disorder. Incomplete penetrance is frequent in some types of cancer, where individuals carry mutations (for example, mutations in the BRCA1 gene which is associated with an increased risk of ovarian cancer), but they may do not develop this condition during their lifetime. Incomplete penetrance may be a result of the interaction between genetic and environmental factors.
