Cell differentiation is an essential process for the overall development, growth, reproduction and longevity of the complex multicellular organisms.

Cell differentiation is the process in which the stem cells become more specialized into different cells. Cell differentiation is an essential process because it creates diversity in life on the planet Earth. It creates diversity within the cells of the body of an organism and allows the cells to create unique structures which fit their individualized functions in that organism.

Cell differentiation is an essential process for the development, growth, reproduction, and longevity of all the complex multicellular organism as it is responsible for the formation and maintenance of different organ systems in an organism.

Answer:

Endosymbiotic theory explains that at a certain point of evolution both mitochondria and chloroplast (cyano bacteria) existed independently as prokaryotic organisms. Which were "engulfed" by eukaryotic cells but instead of being consumed a symbiotic association was developed between the cells, which over various stages of evolution became components / organelles of the eukaryotic cell due to migration of some prokaryotic genes to the eukaryotic nucleus. However, they retained their capacity of duplication due to presence of circular DNA

So, the correct answer is'The mitochondria and chloroplast have their own DNA'

Correct option E - The mouth develops from the blastopore Protostome development involves

The mouth forms from the blastopore in protostomes. The longitudinal pouches of the archenteron give rise to its coelom. They are hence called enterococcus. The embryonic mesoderm is divided to create their coelom.

Protostome translates as "first mouth." The blastopore opens its mouth. The second aperture will develop into the anus.

We estimated that chordates split from echinoderms around 600 million years ago and that arthropods, annelids, and mollusks diverged from deuterostomes (echinoderms and chordates) about 670 million years ago based on the analysis of 18 protein-coding gene loci.

Sight, hearing, smell, taste, and touch are the five senses that make up the human body.

Humans use their sensory organs to experience their five senses. These sensory organs include the tongue and nose for taste, the eyes for sight, the ears for sound, the nose for scent, and the skin for touch. Each sense serves to aid human perception of the outside world so that we can decide what is happening and what is required at the time.

There are certain persons who are less able than others to detect their surroundings. Despite having a condition like blindness or deafness, people can still have rich, fulfilling lives.

The article read by Yuki

Explanation:

The article read by Yuki is more likely to have been peer-reviewed out of the two articles illustrated in the scenarios.

This is because magazine articles are usually written by staff writers or freelance journalists as opposed to professionals that are responsible for writing professional journals. Moreover, magazine articles are intended for general public reading and as such, are written in general, non-technical languages while professional articles are written in technical languages intended for scholarly use.

Articles in magazines are usually unstructured and hardly report scientific results unlike those in professional journals that require well-structured formats.

Consequently, articles in the Professional Journal of Medicine read by Yuki is more likely to be peer-reviewed than the article read by Carmen in Tasty Food magazine.

Answer:

Explanation:

A hypothesis is like a guess you make before you do any research, and a theory is like a conclusion you draw after you see the data. A hypothesis can be right or wrong, but a theory is more likely to be right because it has evidence to back it up. A hypothesis can change if you find new data that contradicts it, but a theory is stable and consistent. For instance, the Cell Theory is a theory that tells us how living things work based on what we see under a microscope and in a lab, while a hypothesis might be an idea about why some animals have different kinds of skin, like fur or scales.

Sometimes, something can be both a theory and a hypothesis, depending on how much evidence it has and how many things it can explain. A theory is a hypothesis that has passed many tests and can explain a lot of things, and a hypothesis is a theory that has not done that yet. For example, the string theory is a hypothesis that tries to tell us what everything is made of, but we don't have any data to prove it. The cell theory, however, is a theory that tells us what living things are made of, and we have lots of data to prove it.

Answer:

Answer:

can be tested by many independent researchers - both

based on observations of natural phenomena - both

makes predictions about future events - both

a tentative statement used to guide scientific investigations - hypothesis

a well-established, highly reliable explanation - theory

Explanation:

While we don't know exactly how many cells are contained within the average dog, we can make a rough approximation. As some sources give a rough estimation of about fifty trillion cells contained within a human body, we can apply this estimate to dogs, being in the ten's of trillions. We must keep in mind that dogs vary greatly in size.

I characterized the theory as a well-supported clarification and the hypothesis as a proposed clarification for testing. I emphasized rehashed experimentation and gave a case of the cell hypothesis.

Based on the given alternatives, the data included in my answer include:

I gave the definitions of hypothesis and theory, clarifying that a hypothesis could be a well-substantiated explanation for a marvel whereas a theory may be a proposed clarification to be tried. I said the importance of rehashed experimentation in approving or negating theories.

I too insinuated the method of testing the hypothesis. Furthermore, I advertised the case of the cell theory as a logical hypothesis. In conclusion, I associated the definitions of hypothesis and theory, highlighting their relationship within the logical strategy where hypotheses are proposed and tried to back or challenge existing hypotheses.

The path of the river will become curvier as the process of erosion and deposition continues over time. Hence, option B is correct.

The removal of soil, rock, or dissolved material from one area on the Earth's crust and subsequent transport to another region for deposition is known as the erosion process.

Rainfall, runoff, melting snow or ice, irrigation, and soil detachment and movement are the main contributors to water erosion. The production of agricultural and forestry products may be threatened by excessive erosion. In addition to having an effect on these structures, erosion can also pollute land surfaces.
