Answer:
a) x4 b) Eyepiece x10 Objective x40
Explanation:
a) x4 magnification
The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.
b)
Eyepiece Lens: the lens at the top of the microscope that you look through. The eyepiece is usually 5x, 10x or 15x power.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers.
To get 400 we need to use a combination that, multiplied together, will give us 400.
If the eyepiece lens is 10x then 400/10 = 40
So if we use the 10x Eyepiece lens with the 40x Objective Lens we will get a total magnification of x400.

What is the mass of an atom with seven protons seven neutrons and eight electrons
Answer:
The atom is a nitrogen atom and the mass of the atom is 14.0067 u.
An atom with seven protons, seven neutrons, and eight electrons has a mass of 14 g.
What is an atom?Atoms are made up of protons, neutrons, and electrons. Each element has an atomic number that corresponds to the number of protons in its nucleus.
Given that,
Number of protons is 7.Number of neutrons is 7.Number of electrons is 8.The mass number of an atom is the sum of its atomic number and neutron number.
Mass number = number of neutron + atomic number
As the atomic number of an element will be equal to the number of protons of such elements, so in this case,
Mass number = 7 + 7Mass number = 14 gThus, the mass of an atom with seven protons, seven neutrons, and eight electrons is 14 g

During a rainstorm, when atoms absorbed by soil from weathered sedimentary rock are washed into a nearby lake, some of the atoms come in contact with similar atoms from fertilizers and
detergents. An algal bloom results. Which cycle is described by this sequence of events?
Hydrologic cycle
Carbon cycle
Phosphorus cycle
Nitrogen cycle
Answer:
Phosphorus cycle
Explanation:
During the time of rainstorm, the atoms are absorbed by the soil for the sedimentary rocks and they are washed down towards a lake and when they come into contact with the similar atoms like those of the detergents and fertilizers they result in an algae bloom which describes the sequence of the phosphorus cycle.Simple carbohydrates are called ___________________.

Organisms are buried under sediment.
Organisms' shapes are preserved in rock.
Answer:
Organisms are buried under the sediment.
Explanation:
Organisms are buried under sediment is the first step in the process during the formation of molded fossils.
What do you mean by molded fossils?
Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold.
Moreover, cast and mold are a type of fossilization where the physical characteristics of organisms are impressed onto rocks, especially coarse porous rocks such as sandstones.
A mold fossil is a complete replica of the shell, formed from when the shell was filled in and surrounded by sediment.

Please mark Brainliest! :)
Height, Steepness and Type of Lava classify a volcano. So, the correct options are (A), (B) and (D).
What are Volcanoes?A volcano is an opening or rupture in the earth's surface which allows magma (hot liquid and semi-liquid rock), volcanic ash and gases to come out from there. When the tectonic plates come together or separate, they will occur. It can also occur in the middle of plates due to volcanic hotspots.
There are three types of Volcanoes-
Cinder Cone VolcanoesComposite Volcanoes (Stratovolcanoes)Shield Volcanoes1. Cinder Cone Volcanoes are the simplest type of volcano which occur when particles and blobs of lava are ejected from a volcanic vent.
2. Composite Volcanoes (Stratovolcanoes) have conduit system inside which channels magma from deep within the Earth to the surface.
3. Shield Volcanoes pours out of shield volcanoes is thin and it can travel for great distances down the shallow slopes of the volcano.
Thus, height, Steepness and Type of Lava classify a volcano. So, the correct options are (A), (B) and (D).

What are the three forms of active transport?
Endocytosis, exocytosis, and cell membrane, are three forms of active transport.
What are the 3 key features of active transport?Active transport calls for a specialized carrier molecule, a protein, and cellular energy expenditure; transfer throughout membranes can therefore arise towards an attention gradient.
What are examples of active transport?Examples of energetic delivery include the transportation of sodium out of the cell and potassium into the mobile through the sodium-potassium pump. Active transport regularly takes area within the inner lining of the small intestine.
