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

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.

Consider two genes that are independent, the A gene and the B gene. Each gene has two alleles (A gene: A1 and A2, B gene: B1 and B2). The frequency of A1 allele at the A gene is 0.85 and the frequency of the B2 allele at the B gene is 0.24. What is the probability of an individual in a randomly mating population of having A1B2|A2B1 as their genotype

Which organisms do you think might be more closely related to each other: a dog and a turtle or a dog and a silkworm
Answer:
Most likely a dog and a turtle.
Explanation:
A Dog and a Turtle organisms do you think might be more closely related to each other, So, the correct option is A.
What is an organism?An organism is defined as any living system which functions as an individual unit where all living things are made up of cells. The concept of organism is based on the concept of the minimum functional unit of life.
Biological organisms are defined as living things capable of responding to stimuli, reproduction, development and homeostasis which are classified by taxonomy into specified groups such as multicellular animals, plants and fungi; or unicellular microorganisms such as protists, bacteria and archaea.
A Dog and a Turtle organisms do you think might be more closely related to each other as both have four legs and belongs to Phylum Chordata.
So, the correct option is A.

how are two identical DNA molecules formed
Answer:
Explanation:
DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands. This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

true or false the typical X shaped chromosomes is the result of DNA replication
Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.
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.
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

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.

species.

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).
