Answer:
So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. The combination makes a unique combination of their parents genes. The scientific study of how traits are passed from parents to children is called 'genetics'.
The best explanation of why children often look like their parents are traits or characteristics are passed on to offspring from parents. The correct option is A).
What is heredity?Heredity refers to the genetic legacy passed down to us from our parents. It can also be defined as traits passed down from generation to generation.
Blood type and eye colour are two common examples of these characteristics. Some disorders can even be passed down from parents to children through heredity. These are known as hereditary or genetic disorders. These disorders are typically incurable.
These are hereditary qualities that are determined by genes. A single gene can also have numerous variations. These are known as alleles. Except for genes on sex chromosomes, every gene in our cells has two copies. These two copies can be identified and referred to as homozygous, or they can be different and referred to as heterozygous.
Therefore, the correct option is A) Traits, or characteristics, are passed on to offspring from parents.

Why is osmosis important to the survival of a cell?
Answer:
to stabilize the internal environment of an organism by keeping the water and inter-cellular fluids levels balanced.
Explanation:
The most important function of osmosis is stabilizing the internal environment of an organism by keeping the water and inter-cellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
Answer:
For a cell to survive, ion concentrations inside and outside the cell need to be the same. If extra ions are not pumped out of the cell, water can enter the cell, causing it to swell and burst.

Carbon dioxide (CO2) is a greenhouse gas. It traps the heat in the atmosphere. Humans have used fossil fuels for only the last few hundred years. When burned, fossil fuels release CO2 into the atmosphere. Why do you think our fossil fuel use is a concern for environmental scientists?
Answer:
humans really heavily on fossil fuels, but unfortunately the more humans use it the more CO2 is being released,and the more greenhouse gases being trapped in our atmosphere, one of the reasons that are causing global warming
Explanation:
I think I could have done better but I cant find the right words to use (sorry)
Answer:
Burning fossil fuels increases the amount of CO2 in the atmosphere. A high level of CO2 throws the carbon cycle out of balance. With more CO2 in the atmosphere, the temperature on Earth increases.

(b) Explain why DNA replication cannot proceed to the regions of the chromosome labeled as I in Figure 1B unless topoisomerase binds ahead of each advancing replication fork in region II
Answer:
The explanation is found below
Explanation:
DNA replication is an important phenomenon that must occur prior to any cell division. Before DNA replication can take place, the double-helical structure of the DNA molecule must unwind. This separation into a Y-shaped replication fork at the origin of replication (where replication starts) is carried out by DNA HELICASE.
However, due to the double-helical nature of the DNA, each strand is so tightly wound to each other. To prevent the strands from getting too tightly wound to each other as the DNA is unwinded, an enzyme called TOPOISOMERASE binds at a binding site close to the replication fork.
Hence, in the diagram, replication will not proceed if TOPOISOMERASE does not bind ahead of each advancing replication fork in region II because the DNA molecule will become super coiled and difficult to separate/unwind in order to continue replication.
DNA replication is the process in which DNA makes a copy of itself during cell division. The separation of two single strands of DNA creates a Y-shape fork and various enzymes play a crucial role in DNA replication.
DNA replication is a vital process in which parental genetic information is copied in the daughter cells before cell division.
The double-helical structure of the DNA is opened with the help of the enzyme DNA helicase.
Due to the double-helical structure of the DNA, each strand is tightly wounded. The strands after the replication bind with the enzyme topoisomerase, to close the replication fork.
The diagram shows replication, which will not proceed in region II because the DNA molecule will be super coiled and unwind it before the replication starts.

why the oceanic white tip shark is a good predator
Answer: The oceanic whitetip shark is one of the most widely ranging sharks, common throughout the warm latitudes of all oceans. It lives in the open ocean, where it is a predator at the top of pelagic food webs. ... They are a primary component of shark feeding frenzies caused when mixed groups of predatory species feed together.
Explanation:
The oceanic white tip shark is an effective predator due to its powerful jaws with sharp teeth, advanced sensory organs for detecting prey, and versatile feeding behavior. These attributes collectively make it a highly skilled and adaptable predator in marine ecosystems.
The oceanic white tip shark is a formidable predator for several reasons:
Physical AttributesThe jaws of a shark are equipped with multiple rows of sharp, serrated teeth, making them highly effective at tearing into their prey. Their streamlined bodies allow for strong and agile swimming capabilities, which are crucial for both chasing prey and avoiding threats.
Sensory AbilitiesOceanic white tip sharks possess a network of sensory organs called the ampullae of Lorenzini. This system can detect electrical fields, which helps them locate prey even when it is hidden or camouflaged.
Feeding BehaviorThese sharks are not picky eaters and have been known to feed on a variety of fish and marine animals. Such versatility in diet contributes significantly to their survival as apex predators in the marine ecosystem.
Thus oceanic white tip shark is a good predator.

How are text messages encoded in radio waves?
Text messages are encoded into radio waves through a process called modulation where they are converted into digital data (binary codes), modulated onto a radio wave, then transmitted. This data is then decoded back into the original text message on the receiver's end.
Explanation:Text messages are converted into binary codes, consisting of ones and zeros, which form a digital data. This data can then be modulated onto an electromagnetic wave, essentially a radio wave. The modulation can occur in the amplitude (AM), frequency (FM), or phase of the wave. This is the method of encoding the digital data into the radio wave.
For example, a common technology that operates in the radio-wave portion of the electromagnetic spectrum is 4G cellular signals, which are around 880 MHz. Satellite-transmitted information is typically carried on microwaves, which require a clear line of sight between the transmitter and receiver due to the short wavelengths involved. Once the radio waves reach the recipient's device, they are decoded back into digital data and finally back into the original text message.

в)
Jupiter and the sun have a similar composition.
Jupiter is larger and colder than the sun.
D
Jupiter and the sun are both stars.
Answer: B) Jupiter and the sun have a similar composition.
Explanation:The only significant difference between the sun and Jupiter is in the sizes i.e jupiter is smaller compared to the size of the sun.
However their similarities is in their composition i.e what they are made up (helium and hydrogen).
The core of Jupiter is made up of liquid metallic hydrogen and the sun's core or center is also made up 34% mass plasma of hydrogen.
