which image is formed when the real image is projected up through the microscope to the plane of the eyepiece?

Answers

Answer 1

Answer:

Answer: flows through wires of flashlight.

Explanation: When the flashlight is turned on, the chemical energy stored in batteries is converted into electrical energy that flows through wires of flof the flashlightshlight. This electrical energy is then transformed first into heat energy and then light energy.

1.How Can You Classify Single-Celled Organisms?Some of the oldest and most common organisms on Earth consist of only one cell. These single-celled, or unicellular, organisms display all of the characteristics of living things. You might think that all unicellular organisms are very similar, but this is not the case. These fascinating creatures are extremely diverse.What characteristics do you think could be used to classify different kinds of single-celled organisms?

True or False, DNA is not always available in a hair sample.

Answers

False, DNA is always available in a hair sample. In forensic analysis of DNA from hair samples is used for identification. Hair is not interchangeably used to describe DNA. However, hair is a source for DNA. Hope this answers the question. Have a nice day.

Answer: The given statement is True.

Nuclear DNA is present in the nucleus of eukaryotic cells. When working with the DNA samples, the best source of nuclear DNA is hair root that anchors the whole shaft of hair. Hair root possesses cells that are called as keratinocytes. These cells are ideal for the extraction of nuclear DNA.

But, DNA is not always available in a hair sample as it can not be extracted from shaft of hair ( since it undergoes cornification that destroys the genetic material of the cells).

Thus, given statement is True.

why is it more important for dna replication to be exact than for transcription or translation to be exact

Answers

Because DNA replication contains essentially all the genetic materials that will be needed in transcription and translation processes. And DNA replication is first step to ensure correct protein synthesis and others as well. But translation and transcription are both important to be exact, actually as incorrect transcription or translation could lead to useless proteins or etc.

in apex the answer is : an error in dna replication would affect many generations of cells

Which statement represents a fact about the rock cycle?A. All the processes involved in the rock cycle occur beneath the surface of Earth.

B. Fossils, skeletal remains, and living organisms do not play a role in the rock cycle.

C. The rock cycle is driven by energy from the Sun as well as from the interior of Earth.

D. Every transformation between states happens as a result of heat from magma.

E. Nearly all rocks transition from one form to another on a human timescale.

Answers

The answer is : The rock cycle is driven by energy from the Sun as well as from the interior of Earth. The sun provides energy for surface processes such as weathering, erosion, and transport. This is the one of the major source of energy for the rock cycle. Weathering happens when there is a interaction with the air, water and organism which cause the rock to break down, and the pieces of rock are carried away by wind, moving water, etc. through erosion.

Explain why multicellular organisms require a ventilation system?? include reasons on
surface area to volume ratio
cells depp within the body
and number of cells

Answers

Ventilation maintains a steep concentration gradient, blood at the exchange surface usually has lower O2 and higher CO2 content than the air (of for fish, the water) at the exchange surface. This is what allows for diffusion of O2 into the blood and CO2 out of the blood. Multicellular organisms have a greater number of cells so will have a higher energy demand than single cellular organisms, this demand can only be met by allowing the cells to respire, a ventilation system brings oxygen molecules which are a raw product of respiration into the hemoglobin of the blood to be transported to tissues. As surface area : volume ratio is very low so if there was no ventilation system and the organism instead relied on exchange of materials through the exposed skin it would be very difficult to met the high energy demand as less O2 and CO2 would be able to be exchanged.

In multicellular organisms, the division of labor provided by these bodies grouped into specialized devices imposes a number of constraints.

One of the constraints is that it is necessary for all cells in the body to be well supplied with both nutrients and oxygen. The transition to multicellularity requires the establishment of a circulatory system and a respiratory system for the supply and purification systems for the disposal of waste.

The amount of oxygen required to breathe depends on:

Ratio surface / volume plus it is small and the intake by the respiratory system must be important.

The depth of the cells, which evolves proportionally with the oxygen supply required.

The number of cells that also evolves proportionally with the oxygen supply required.

Which of the following statements accurately describes the process of dating Earth's history?a. Scientists use radiometric dating to determine the relative age of a new fossil.
b. Scientists use relative dating to determine the absolute age of a new fossil.
c. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
d. Scientists use index fossils to determine the specific years of age of a new fossil.

Answers

Radiometric dating and radioactive dating are two different names for the same method.

This method serves to determine the absolute age of a fossil: the correct answer is C.

Relative dating and index fossil both serve to determine the relative age of the fossils.
