What best describes the scientific process?

Answer:

The body has two lines of natural defense to protect against infection. The first are physical barriers, such as the skin, body secretions and mucous membranes. The second line of defense is the immune system. Specialized immune cells coordinate and execute attacks to kill germs that make it past the body's physical barriers.

Answer:

Plants fibers are obtained from cotton plants and jute plants.

Explanation:

In 1964, Bell Labs scientists Arno Penzias and Robert A. Wilson were conducting experiments with the Holmdel Horn Antenna, an extremely sensitive device originally used to detect radio waves that were bounced off Echo balloon satellites, and later Telstar, the first active communications satellite. These radio waves were so weak, that it became critical to eliminate all possible interference in order to detect them.

Despite taking all conceivable steps to eliminate interference, they continually detected a strange, buzzing noise that was coming from all parts of the sky at all times of day and night. They did a range of additional testing on the equipment, and even removed some pigeons that were nesting in the antenna and their associate detritus. Still, the sound persisted. They ultimately determined that the noise was coming from outside of our galaxy

Almost by chance, they later learned that researchers and astrophysicists Robert H. Dicke, Jim Peebles and David Wilkinson at nearby Princeton University were looking for a way to detect residual radiation that they believed would have resulted from the Big Bang. As it turned out, the radiation detected by Penzias and Wilson was a perfect match for what the Princeton researchers had predicted, and hence made history.

Arno Penzias (left), Robert Wilson (center) and Keith Jefferts (right) look through a model of the universe to the constellation Orion where, for the first time, they discovered carbon monoxide in outer space.

From the archives

An audio recording of the CMBR noise was captured and narrated by Robert A. Wilson. This discovery in 1964 by Penzias and Wilson, announced in a Bell Labs press release, earned the researchers a Nobel Prize in Physics and provided the basis for future astronomical discoveries.

B. Pancreas; Digestive, Endocrine

The pancreas is an organ directly associated with the digestive and Endocrine systems.

A intricate system of glands and organs makes up the endocrine system. Your body's metabolism, energy level, reproduction, growth and development, and response to injury, stress, and mood are all regulated and coordinated by hormones.

The endocrine system is made up of the following components:

The optic chiasm, where the optic nerves behind each eye intersect, and the hypothalamus are both found at the base of the brain. In the center of the brain, beneath the corpus callosum, is where you'll find the pineal body.

Therefore, The pancreas is an organ directly associated with the digestive and Endocrine systems.

The virus lacks strcutures to replicate genetic material.

Explanation:

They can replicate it, but don't have structures to do it without the help of a cell. They USE the cell to replicate it but cannot do it themself.

Virus lacks genetic matrial? It has DNA.

When microscopes were first used hundreds of years ago, scientists discovered that a single drop of water contains many particles that the human eye is unable to detect on its own. This statement best describes the use of microscopes over the last several hundred years. Thus, option A is correct.

The statement that best describes the development of the theories that has been connected microscopic as well as macroscopic phenomena has took several hundred years for the scientists just to develop current theories, as well as they are still being revised to this same process.

Most of the scientific theories has been involving the microscopic and the macroscopic phenomenon which have been taken several years to be developed atlast however, this theories are still under revision till date. The microscopes used today are much more powerful and have allowed scientists to make discoveries about smaller living things.

Therefore, This statement best describes the use of microscopes over the last several hundred years. Thus, option A is correct.

Answer:

The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.

Explanation:

During the main sequence stage of the life cycle of a star, it cycles, appearing brighter and dimmer in turns.

The life cycle of a star is a cycle which describes the time from the birth or formation of the star, through its growth and expansion, and then finally the death of the star.

The life cycle of a star occurs in seven stages and occurs over billions of years.

One of the stages is the main sequence stage.

During the main sequence stage of a star's life, it cycles, appearing brighter and dimmer in turns.

Therefore, the life cycle of a star is a cycle from the birth to death of the star.

Answer:

Observations; control.

Explanation:

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an  observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

On the other hand, a control experiment  can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same  situation by the scientist without involving or using the suspected condition.

Hence, science rejects any hypothesis not supported by observations and the results of control experiments.

This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

Answer:

Hello. You did not put the options, but we can say that the execution of mitosis is what makes it important that the proportion between the colume and the cell surface area is not small.

Explanation:

The ratio between the surface area of ​​a cell and the volume is very large and this is essential for mitosis to occur and for all cells in the same tissue to have the same content and the same drum.

If a cell increases ten times its surface area, it will increase its volume a thousand times. This shows that the cell volume has a much larger proportion than the surface. This makes the cell have a fast metabolic rate and needs to absorb many nutrients, in addition to making a strong exchange of gases with the external environment. This absorption of nutrients so intense, is essential for the cell to enter mitosis and generate two equal cells. This is because during the growth phase the cell will increase in volume until the growth limit of its surface area, once this limit is reached, the cell will have to undergo mitosis and will have enough nutrients for the entire process.

Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.

Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.

Answer:

The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell 's activities, while RNA converts that code into proteins to carry out cellular functions.

Explanation:

RNA:

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

DNA:

The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
