Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.
Answer:
The correct answer is -
1) point mutation
2) deletion
3) inversion
4) frameshift mutation.
Explanation:
Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.
Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.
When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.
If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.

Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenate into a pellet in the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen.

This pellet most likely contains
1. peroxisomes
2. mitochondria
3. lysosome
4. Golgi complex
5. endoplasmic reticulum
Answer:
2. Mitochondria
Explanation:
Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.
The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.
Mitochondria are more grouped in areas or tissues with higher energetical requirements.
As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.
By considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.
Cellular respiration is a series of reactions by which aerobic cells consume oxygen and nutrients (e.g. glucose) to produce ATP and carbon dioxide.
Cellular respiration has three sequential steps: glycolysis, the Krebs cycle and oxidative phosphorylation.
Mitochondria are the energy center of the eukaryotic cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria, while glycolysis occurs in the cytoplasm.
The Krebs cycle produces a four-carbon molecule known as succinate.
Adenosine triphosphate (ATP), the energy coin of the cell, is produced from ADP and phosphate (Pi) in the three stages of cellular respiration.
Finally, oxygen is consumed during oxidative phosphorylation.
In conclusion, by considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

Explanation:
Antibiotics are added to the animal feed or drinking water of cattle, hogs, poultry and other food-producing animals to help them gain weight faster or use less food to gain weight.
Because all uses of antimicrobial drugs, animals contribute to the development of antimicrobial resistance, it is important to use these drugs only when medically necessary.
the production (e.g. growth enhancement) purposes as well as for the treatment, control or prevention of animal diseases. Even today, it is not entirely understood how these drugs make animals grow faster. The drugs are primarily added to feed, although they are sometimes added to the animals’ drinking water.

7 difference between Arteries, vain and capillaries
Answer: Hope this helps answer in explanation.
Explanation:
1) These are responsible for the transportation of blood from the heart to all parts of the body. These vessels collect blood through capillaries and transport it towards the heart. These vessels connect arteries and veins.
2. All arteries carry oxygenated blood except pulmonary arteries which carry deoxygenated blood. All veins carry deoxygenated blood except pulmonary veins which carry oxygenated blood. These carry mixed oxygenated and deoxygenated blood.
3. Arteries have no valves in them except at the base of the pulmonary trunk and aorta. Valves are present in veins. These valves prevent the backflow of blood. There are no valves in them.
4. Arteries have high blood pressure. Veins have low blood pressure. There is falling pressure in them.
5. In arteries, waves of blood pressure or pulse due to heartbeat can be detected. There is no pulse. There is no pulse.
6. Blood flows rapidly between 400-500mm per second in the aorta and decreasing in arteries and arterioles. The rate of blood flow increases from smaller to larger veins. Blood flow is slowest which is less than 1mm per second.
7. Arteries have a smaller bore and thick walls. Veins have a larger bore and thin walls. Capillaries have a larger bore and the wall is of one cell in thickness.
8. There are thick muscle layers and elastic fibers present. The elasticity helps to change the pulsating flow of blood. There are thin muscle layer and less elastic fibers present in veins. So, they are less elastic. No muscles or elastic fibers are present.
9. There is no exchange of materials. There is no exchange of materials. These are responsible for the exchange of gases and nutrients.
As mercury moves up the trophic levels in food chains, its concentration
Stays the same
Increases
Decreases
Is eliminated
Answer:
Increases
Explanation:
The concentration of mercury will increases as it moves up the food chain because of biomagnification. For example, a school of small fish consumes a minute amount of mercury each, but then a larger fish eats five of the smaller fish. After this the larger fish has more mercury in its system than one small fish because it ate five small fish (along with the mercury in each of the small fish). Now a seal eats multiple large fish. Overall, the seal has the highest mercury concentration out of all the animals mentioned.
Biomagnification is "the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed."

A
Organism-B
Answer: Click or tap here to enter text.
Answer:
The new modification in Organism B is the tail.
Explanation:
This might indicate that the organism has to sprint in order to catch prey or to get away from predators. The organism is most likely not a prey, since it has sharp teeth, making it a carnivore. The tail helps in stabilizing the animal while running. The animal might have new threats that have developed over the years (like humans).

Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary tube as the temperature rises. Suppose a mercury thermometer contains 3.380g of mercury and has a capillary that is 0.200mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0 0C to 25.0 0C
Answer:
3.5 cm
Explanation:
Mass of mercury = 3.380
Diameter = 0.200
At t = 0 and 25 degrees we have 13.596 and 13.543 as density
At 0 degree = v = 3.380/13.596 = 0.2485
At 25 degrees = 3.380/13.534 = 0.2497
We use volume of cylinder to get height
At 0⁰ height = 7.91
At 25⁰ = 7.944
The difference in height = 0.035
Multiply by 100 = 0.35 x100
= 3.5cm
