Where are the instructions that control a
cell's activities found?
Answer:
In the nucleus
Explanation:
The location depends on the type of the cell (whether animal or plant).
If it is an animal cell it is located in the center. And if a plant cell it is located around the edge pf the cell
The nucleus is a sub-cellular structure that controls all activities done within the cell.
Answer:
The instructions that control a cell's activities found in the nucleus.
Explanation:
Each of your cells has a boss, too and that is the nucleus.

How does this image compare to the white blood cells you saw using Stella’s compound microscope? What are the pros and cons of using electron and compound microscopes? In your response consider cost and ease of use.
Answer:
The Resolution and Magnify power are the major differences between the electron microscope compare to compound microscope. This is due to the source of power for the operation,Light rays of (400-700nm) are used by the compound microscopes,while short frequencies beam of electrons of( 1 nm)are used by the Electron Microscope.
The compound microscope consists of objective lens with short focal length.They are therefore used for magnification of tiny objects.While the E. microscope makes use of beam of electrons(compare to light rays in the compound microscope) with higher resolutions.The beam of electrons are focused by magnetic lenses to give images.
Electron microscope is cumbersome to use,it is expensive, requires a lot of expertise, and occupies large space.
Compound are less expensive with low maintenance,it does not requires expertise;very easy to operate, and can easily be moved about.
There is low risk of radiation with compound,lower magnification,both dead and living creatures can be used.
E.microscope,has high radiation risk,higher magnification, with only dead materials.
Explanation:
White blood cells are the immune cells that protect the body. They are also known as leukocytes or leucocytes.
The compound microscope magnifies objects lesser than the electron microscope. We can see higher magnified things in the electron microscope.
Pros and cons of electron and compound microscopeCompound microscopes are easier to move and set up because they are small and light.Electron microscopes are heavy and higher. They are harder to set up and move.Electron microscopes use electromagnet glasses, whereas compound microscopes use glass lenses.Compound microscopes are cheaper than electron microscopes.Thus, these are the pros and cons of Compound microscopes and Electron microscopes.

Most of Earth's volume is contained in the
O lithosphere
O crust
O asthenosphere
O mantle
Answer:
mantle
Explanation:
The mantle takes up most of the Earth's volume. The mantle makes up 84% of the Earth's total volume.
Answer:
Mantle
Explanation:
The mantle is the mostly-solid bulk of Earth's interior. (1802 miles) thick, and makes up a whopping 84% of Earth's total volume. That allows the crust to “float” on the sometimes more malleable mantle.

Which specialized carbohydrate is used in shrimp exoskeletons?
Answer:
A specialized carbohydrate that is used for structure in shrimp is called chitin. Not only it is found in the shrimp cells, but also on other crustaceans such as crabs and lobsters. Chitin is a derivative of glucose and a characteristic element in the exoskeletons of crustaceans, cell walls of fungi, internal shells of squids and octopuses, and scales of fish.
Explanation:
The specialized carbohydrate that is used in shrimp exoskeletons is chitin.
An exoskeleton refers to an external skeleton that protects and supports the body of an animal. The specialized carbohydrate that is used in shrimp exoskeletons is chitin.
Chitin is a fibrous substance that's made up of polysaccharides. It's the major constituent in the exoskeleton of arthropods. Chitin can also be found in crustaceans. It is a derivative of glucose.

Match the hydrologic term to its definition.
Answer:
1st term- groundwater discharge
2nd term- subsurface runoff
3rd term- surface runoff
4th term- groundwater runoff
Explanation:
I hope this helps:)
Surface runoff: falling rainwater that flows over the ground.
Subsurface runoff: the water that infiltrates in the vadose zone; an example is falling rainwater that gets absorbed into the soil
Groundwater runoff: describes water pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer.
Groundwater discharge: this describes the movement of groundwater from the subsurface to the surface i.e. groundwater returns back to land.
How do you explain surface runoff?Runoff is nothing more than water "running off" the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
What is a runoff in groundwater?Runoff is the water that is pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream, or watershed.

What could happen if a person doesn’t get the proper amount of protein in his or her diet? The impact of a diet lacking in protein would be of little consequence. Stored proteins would assist in creating new amino acids that the body needs. The body would break down existing muscle to get the amino acids it needs.
Answer:
The body would break down existing muscle to get the amino acids it needs.
Explanation:
If a person doesn’t get the proper amount of protein in his or her diet, then the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
What is the function of proteins?Proteins are made up of building blocks called amino acids; some of these amino acids can be produced by the body, while others must be obtained through the diet, so if a person does not consume enough dietary protein, their body may not have access to enough essential amino acids to build and repair tissues or produce enzymes. As a result, the body may break down muscle tissue in order to obtain the amino acids it requires, resulting in muscle wasting; the immune system may not function optimally; and so on.
Hence, the body would break down existing muscle to get the amino acids it needs, which are present in the last option.

There share some common features with eukaryotes and extremophilic and obligate anaerobe in nature as they can survive under extreme condition and grow in absence of oxygen.
So they under go in the process of methanogenesis and called as methanogens.
Their cell membrane is made up of lipids and cell wall is composed of Pseudomurein, which provide protection them against adverse effect.

(604 (1) 0 + 111e13) và (O2 + CK Og
Where is the energy shown in the equation transferred as a result of photosynthesis?
into water
into the air
into sugars
into the ground
Answer:
The chemical equation of Photosynthesis in the question is not clear but the energy goes into water.
The answer is "Into Water"
Explanation:
Photosynthesis is a metabolic reaction which involves the synthesis of sugars (Glucose) in plants using carbondioxide and water input in the presence of sunlight. Photosynthesis, which occurs in the Chloroplast of plant cells, occurs in two stages viz: light dependent stage and light-independent stage.
The light dependent stage involves the production of ATP and NADPH molecules, which will be used in the light-independent stage. The chemical equation of photosynthesis is as follows:
6CO2 + 6H2O ---light energy--> C6H12O6 + 6O2
The light energy input in this reaction (from sunlight) is used in the light-dependent stage to break down water molecules, a process called PHOTOLYSIS OF WATER. The photolysis of water releases electrons and protons used to build a proton pump for the synthesis of ATP.
Therefore, the energy input from photosynthetic process goes into water.
