B. only carpel is involved
C .both stamens and carpel are involved
D. only stamen is involved
Answers
Answer:
Two parents are involvede
Explanation:
This is because vegetative propagation is a form of asexual reproduction that involve a single parent where new plant is formed from the fragment of parts of the reproductive part. Plants reproduce from stems, roots, branches,leaves. This can be achieve through layering, cuttings, graftings e.t.c. Two parents are involved because a part of a plants can be cut and grafted into another plants to get desired characteristics.

O Only plant cells use cellular respiration. Only plant cells have a nucleus containing DNA. Unlike plant cells, animal cells cannot make their own food. Only animal cells have a cell wall.
Answers
During prophase, the parent cell will have 48 chromatids. This is because during interphase, the DNA replicates, resulting in each chromosome consisting of two sister chromatids.
Therefore, if the parent cell has 24 chromosomes, it will have a total of 48 chromatids during prophase.
Regarding the major difference between plant cells and animal cells, the most accurate statement is: "Only plant cells have a cell wall." Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection to the cell. Animal cells, on the other hand, do not have a cell wall. Hence option D is correct.

what has “sprung up” all over phoenix and why is this a problem?
Answers
Drought has “sprung up” all over Phoenix.
How Drought has become a problem in Phoenix?About 40 million people in the southwest depend on the Colorado River for their water supply, but it is currently experiencing catastrophically dry conditions. It has been the driest two decades in 1,200 years. Phoenix is one of at least six Arizona cities that have officially declared water shortages. This desert area gets less than 8 inches of rain a year.As Phoenix and its neighbors continue their relentless development — Arizona's population has more than quadrupled in the past 50 years, from 1.8 million in 1970 to 7.2 million today — it has long been debatable how to supply enough water to sustain a city this size in the desert. The potential effects of drought on their daily life, are an increase in wildfires, a decrease in local food, and a decrease in leisure activities because of low lake water levels.How is Phoenix coping up with dry conditions?Phoenix has activated its drought management plan and is asking residents to use less water. The City of Phoenix issued a stage 1 water alert this year. With the alert, individuals are being advised to use less water in ways that won't significantly affect their daily life. One of the simplest and most efficient methods to preserve water, according to the city, is to water landscapes appropriately. The city concentrates on consumer outreach and education about the drought conditions rather than enforcement because the water reductions are voluntary.Phoenix has weathered every drought without having to impose forced water use restrictions or prohibitions thanks to long-term planning, investments in alternate water supply options, and a track record of success with water conservation.To learn more about Phoenix visit:

Initially. most weight loss from a low carbohydrate diet can be attributed to fat loss. True False Enzymes are protein molecules that are needed to break down macronutrients. True False
Answers
The statements that are given are:
- Initially most weight loss from a low carbohydrate diet can be attributed to fat loss: True
- Enzymes are protein molecules that are needed to break down macronutrients: True
Initially most weight loss from a low carbohydrate diet can be attributed to fat loss: True
Initially, most weight loss from a low carbohydrate diet can be attributed to fat loss. This is because, in the absence of carbohydrates, the body shifts to using fat for energy. Fat is the body's main fuel source, so the more you burn, the more weight you lose.
Enzymes are protein molecules that are needed to break down macronutrients: True
Enzymes are protein molecules that are needed to break down macronutrients. Each enzyme is specific to a particular macronutrient. For example, amylase breaks down carbohydrates, protease breaks down protein, and lipase breaks down fat. Without enzymes, macronutrients would not be absorbed and utilized by the body.

What situations can occur in the population that may cause the MK number to change yearly?
Answers
The MK number is a measure of the migration of a population, specifically the number of net migrants per 1,000 people in a population. There are several situations that can occur in a population that may cause the MK number to change yearly.
One of the main factors that can influence the MK number is economic conditions. When economic conditions are favorable in a particular region, it can attract a large number of people to migrate to that region. For example, if there is a surge in job opportunities or an increase in wages in a particular region, it may lead to an increase in the number of people migrating to that region, resulting in a higher MK number.Similarly, political factors can also play a crucial role in influencing the MK number. If there are political upheavals, wars, or conflicts in a particular region, it can lead to a large number of people migrating to other areas for safety and security reasons. This can lead to a decrease in the MK number of the region affected by the conflict and an increase in the MK number of the regions where the migrants move to.Natural disasters such as earthquakes, floods, and hurricanes can also significantly impact the MK number. In the aftermath of such disasters, people may be forced to migrate to other areas to seek shelter, food, and other basic needs. This can lead to an increase in the MK number of the regions where the migrants move to.

Viruses and bacteria are two types of microorganisms that can cause disease in humans and other animals. While they share some similarities, they also have many differences in terms of their structure, replication, and the ways in which they cause disease.
Bacteria are single-celled organisms that come in many different shapes and sizes. They can be either beneficial or harmful to humans, depending on the species and the circumstances. Some bacteria live in the human gut and help to digest food, while others can cause infections such as strep throat, pneumonia, and meningitis. Bacteria have a cell wall that provides structural support and protection, and they reproduce through a process called binary fission, in which one cell divides into two identical cells.
Viruses, on the other hand, are not technically alive, as they cannot replicate or carry out metabolic processes on their own. Instead, they rely on host cells to reproduce and spread. Viruses are made up of a core of genetic material (either DNA or RNA) surrounded by a protein coat called a capsid. Some viruses also have an outer envelope made up of lipids. Viruses attach themselves to host cells and inject their genetic material into the cell, which then takes over the host's machinery to produce more virus particles.
While bacteria can cause disease by invading and damaging host tissues, viruses typically cause disease by hijacking host cells and using them to produce more virus particles. Some common viral infections in humans include the common cold, flu, and HIV.
Both bacteria and viruses can be treated with antibiotics or antiviral medications, but these treatments can be less effective or even ineffective if the microorganism has developed resistance to the medication. Prevention measures such as vaccinations and good hygiene practices are often the best way to control the spread of these microorganisms.
In summary, bacteria and viruses are two distinct types of microorganisms that can cause disease in humans and animals. Bacteria are single-celled organisms with a cell wall that can reproduce through binary fission, while viruses are not technically alive and rely on host cells to replicate. Understanding the differences between these microorganisms is essential for preventing and treating infectious diseases.

Esther was on the YMCA diving team. She was on the 30 meter platform preparing to do a dive. If Esther's mass was 50 kg and she hit the water with a force of 980 N, what was her acceleration?
Answers
The acceleration of Esther on the YMCA was found to be about 19.6 m/s^2
What are the three acceleration laws?
Unless pushed upon by a force, every item travels in a straight line. An object's acceleration is directly proportional to the net force applied and inversely proportional to the object's mass. There is an equal and opposite reaction to every action.
In basic terms, what is acceleration?
Acceleration is the rate at which velocity varies over time, both in terms of speed and direction. A point or object travelling in a straight path is accelerated if it accelerates or decelerates. Even if the speed is constant, motion on a circle is accelerated because the direction is constantly changing.
as per the formula F=ma
then this formula was rewritten as a=F/m
where m= mass = 50Kg
F= force exerted =980N
acceleration (a) = 980/50
a =19.6 m/s^2

over time.
Answers
The speed of the particles while the water undergoes a change of state remains the same.
The average speed of the particles of a substance also changes when it changes state, such as from solid to liquid or from liquid to gas. This is due to the fact that the force of attraction between particles in different states of matter is different. A solid expands when heated and eventually melts because the particles inside it absorb thermal energy and vibrate more rapidly around their fixed positions. During this process the average speed of the particles gradually increases.
Therefore, the correct option is D.

C
Replication will occur via RNA polymerase
D
Replication will require a DNA template from another source.
Answers
In E. coli, a mutation in a gene called dna B that alters the helicase that typically acts at the origin would result in B) No replication fork will be formed.
DNA helicase is an enzyme that separates DNA strands during DNA replication. It catalyzes the unwinding of the parental double helix, allowing each strand to act as a template for the synthesis of a new complementary strand by DNA polymerase.
DNA helicase separates the DNA strands at a replication fork by using ATP hydrolysis to travel along the DNA molecule in a 5' to 3' direction. ATP hydrolysis unwinds the double helix by breaking the hydrogen bonds between complementary bases in the two strands.
During DNA replication, the replication fork is the site where the parental DNA double strand separates, and the new daughter DNA strands are synthesized by DNA polymerase.
It is a Y-shaped structure that forms when the DNA double helix separates into two strands at the origin of replication, and each strand acts as a template for DNA synthesis. The replication fork moves along the DNA molecule as DNA synthesis continues, and replication is complete when the two forks meet at the termination site.
