Explanation:
Answer:
Option 1
Explanation:
without making any other adjustments the _____ can be increased by focusing properly.
Resolution is the ability that a microscope has to distinguish fine details. Without making any other adjustments the RESOLUTION can be increased by focusing properly in a brightfield microscope.
A brightfield microscope (also called compound light microscope) is a light microscope that produces dark images against a bright background.
The brightfield microscope is widely used in cellular biology and microbiological laboratories.
The resolution of the brightfield microscope is limited to 0.2 micrometers (µm).
This maximum value can be reached by changing the objective lens.

Which layer of the
earth has the greatest
density? Why?
Answer: metal inner core
Explanation:
It is made of the densest components & it is under the greatest compression; due to the overlying layers.
The inner core of Earth has the greatest density due to:
- The inner core is made of solid iron and nickel
- The inner core gets consolidated due to pressure exerted by the other top layers.
What are the different layers of the Earth?
Generally the Earth is made of three different layers:
- Crust- The outer layer
- Mantle - The Middle Layer
- Core - The Inner Layer.
Crust:
Outer layer of the Earth and is thin, brittle and cold compared to other layers.
It is majorly made of light elements especially silica, aluminum and oxygen.
The thickness of crust varies for for land and ocean where the former is thicker than latter.
Mantle:
It is around 3000 km thick and is the thickest layer of the Earth. It starts mere at 30 km from the earth's crust.
It is majorly made of Iron, Magnesium and silicon and is dense, hot and semi solid.
The upper part of the mantle is liquid in nature called as Asthenosphere and it is believed that tectonic plates rides upon here and slide across.
Core:
Core is further divided into Outer core and Inner core.
Outer core is made of iron and nickel and is liquid in nature. It is heated largely by the radioactive decay of the elements of the uranium and thorium and this liquid churn huge turbulent current.
Inner core is a solid metal ball having radius of 1220 km. It is extremely dense and is mostly made of iron and nickel.
The temperature of inner core is similar to that of the surface of sun along with high amount of pressure.
Thus this layer has the greatest density amongst all the layers of the Earth.

in the late 1980's scientists discovered a new fossil skeleton that changed their thinking about the events leading to life on land. This new fossil
had legs and feet, but ankles that were too weak to support it's weight on land. It had lungs and gills, but the rib cage was too short to prevent
the chest cavity from collapsing when the animal was on land. These structures suggested that limbs evolved before retrapods moved onto
land. What is the name of this new fossil skeleton?

What is a cell?Cells are the fundamental cornerstones of all life. Gazillions of cells make up the human body.
They support the body's framework, absorb nutrients from food, convert those calories into energy, and perform specialized functions.
The cell, first discovered by Robert Hooke in 1665, has a rich and interesting history that has led to many of today's scientific advances.
Cell theory is a biological theory first proposed in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Thus, the correct option is B.
