Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.

Question 1
Explain why your model demonstrates how crossing over is important to genetic variation in a species.
Question 2
Look at the offspring you created in your model. Have any of the offspring inherited a more beneficial genetic combination than the others? How could this affect their survival? Explain your reasoning.
Question 3
Why is it impossible to predict the phenotype of the offspring by observing only the phenotype of the two parents?
Answer:
the last one is:
In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.
Explanation:
Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.
What do you mean by crossing over process?Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.

quickly moves their hand away. Which body systems have worked
together to move the hand away from the sharp object? *
A-The immune system senses pathogens from the sharp object and sends a message
to the nervous system to move the hand away.
B-The nervous system senses pain from the sharp object and sends a message to the
skeletal system to move the hand away.
C-The nervous system senses pain from the sharp object and sends a message to the
muscular system to move the hand away.
D-The immune system senses pathogens from the sharp object and sends a message
to the muscular system to move the hand away.
Answer: the answer is obviously C
Explanation: the nervous system is the main system to deal with pain so that narows it down to B or C so then you see that b talks about sending signals to the skeletal system, well, thats not posible without the muscular system, which literally leads you to C

what did Miescher contribute to the discovery of DNA? When was this discovery made?
Answer:
Explanation:
In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.

How would you describe the solvent front?
Answer:
In chromatography, the solvent front is the position on the TLC plate indicating the furthest distance travelled by the developing solvent (or eluent) Once a TLC place is developed in a TLC chamber, the plate is removed from the chamber and a pencil is used to quickly mark the furthest point travelled by the solvent
4. A woman pushes a stroller with a force of 8.2 N and performs 28.7 J of work on the stroller. Over what distance was the
Force applied?
Answer:
3.5m
Explanation:
Given parameters:
Force applied = 8.2N
Work done = 28.7J
Unknown:
Distance through which the force was applied = ?
Solution:
Work done is the force applied on body to move it through a particular distance.
Work done = Force x distance
Now insert the parameters and solve;
28.7 = 8.2 x distance
distance = 3.5m
You notice that a group of students went on a hiking trip to Cockscomb basin. They are asked to climb a hill, by the time they reach the top of the hill some of them are almost out of breath, while others don't even make it to the top of the hill. Only a few seem not to be affected much by the climb. Plan and design an experiment in which you offer a possible explanation for the differences in breathing rate.
Answer:
It depends on the stamina of the individual.
Explanation:
The possible explanation for the differences in breathing rate is related to the daily activities of the individuals. For example, if the daily activities of the people are hard so it has big stamina and experience no difficulty in the climbing of a hill while those people who has little hard daily activities have low stamina and their breathing rates increases while climbing a hill. Where as those people who perform no daily activities have no stamina and will be unable to climb on the hill.

The diagram below represents the distribution of some molecules inside and outside of an artificial cell over a period of time .
Which statement is best supported by the diagram?
1. Oxygen molecules entered the cell over time by active transport.
2. Water molecules are too large to enter or leave the cell, so they remained where they were at the start of the investigation.
3. Protein molecule are kept inside of the cell because the cell needs them.
4. The protein molecules are too large to diffuse out the cell.
Answer:it’s B
Explanation:
No explanation needed
The given diagram describes that 2. Water molecules are too large to enter or leave the cell, so they remained where they were at the start of the investigation.
A cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.

Provide at least three reasons why friction is needed.
Answer:
Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses.
Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding. In those cases, there is an advantage of having friction.
Quite often uses of frction can be seen from how things would be without friction. Without friction, you would not be able to walk, drive a car, or hold objects. Pens and pencils would not work.
Explanation:
Answer:
Friction allows people and objects to move. It provides traction for an object to start moving or change direction. It can also give people a better grip on objects. Finally, friction keeps objects in place when they are set down.

Weather satellites show where weather fronts are moving, what they look like from space, and how much water is in the atmosphere.
What are weather satellites?A weather satellite, also known as a meteorological satellite, is a type of Earth monitoring satellite that is predominantly used to monitor the Earth's weather and climate.
Satellites can be polar orbiting (covering the entire Earth asynchronously) or geostationary (covering the entire Earth synchronously) (hovering over the same spot on the equator).
Heat energy in the infrared spectrum is detected by the weather satellite (infrared energy is invisible to human eye). The satellite image displays objects based on their temperature (whether they are clouds, water, or land surfaces).
Observing the Earth from space with environmental satellites is one of the most important tools for forecasting weather, analyzing climate, and monitoring hazards around the world.
