Answer:
There are many different kinds of microscopes. A magnifying glass is a simple microscope. The term microscope commonly refers to a compound microscope. These Microsoft are called compound because they are made of several glass lenses in a tube. The total magnifying power of a microscope is the product of the magnifying power of the lens is in the ips and the magnifying power of the lens in the objective.. Most compound microscopes can magnify a specimen up to 400 times as real size. Microscope allow you to see fine details. Space is between objects that are closer together than 0.1 mm can be seen. The ability of a microscope to separate small distances is called resolving power. If the resolving power is not good the image will be blurred. When you look into the eye piece of microscope the circular area you see is the field of view when a ruler is placed across the opening of the stage the field of view can be measured in millimeters. Sharpening an image under high magnification used the Find adjustment knobs. The part of the microscope that holds the Microscope slide is called the stage.

Where, in terms of an ellipse, is the Sun located with respect to the orbit of each planet? Which
one of Kepler's Laws does your answer support?
Answers
Answer:
focus
The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit. Kepler's Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits.
Complete this sentence. Excess ____________ from human activities can cause harmful algal blooms (HABs), such as red tide, that produce toxic effects on aquatic species, marine mammals, and birds, as well as on the humans who eat them.
Nitrogen
Carbon
Salt
Heat
Answers
Answer: Nitrogen
Explanation:
Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. Harmful algal blooms are mainly the result of a type of algae called cyanobacteria, also known as blue-green algae.
The answer is nitrogen, nitrogen helps algae grow and when it grows in excess it takes away the dissolved oxygen from the water which kills off fish, which puts more nitrogen in the water making algae grow even more until it snowballs and destroys the aforementioned ecosystem.

Explanation:
What is the metabolic process that breaks down organic molecules to release energy to be used by cells?
A. cellular respiration
B. light dependent cycle
C. light independent cycle
D. photosynthesis
Answers
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises. Thus, option A is correct.
What importance of cellular respiration in an organism?As oxygen tension dropped, so did breathing rate, which eventually reached nil at low oxygen tensions.
Cell density had no bearing on this outcome. We provide a model to explain the observed impact of oxygen tension on cellular oxygen uptake.
As a result, increased cellular respiration is often associated with warmer temperatures.
Carbon dioxide concentration: The rate of respiration is inversely correlated with carbon dioxide concentration.
Increased carbon dioxide levels and a lack of oxygen have a negative impact on aerobic respiration rate.
Therefore, cellular respiration is the metabolic process that breaks down organic molecules to release energy to be used by cells.

Answers
The scientific community disagrees about the rate of global climate change (Option A). The occurrence of global warming is widely accepted by the scientific community.
Global climate change refers to the fluctuations in temperatures worldwide.
Global climate change is caused by the use of fossil fuels such as oil, coal and natural gas, which are known to be associated with the increasing concentration of greenhouse gases in the atmosphere.
The greenhouse gases include, among others, carbon dioxide (CO2) and methane (CH4).

Which of the following best describes an antigen?
Answers
B. A recognition molecule on the surface of the cells.
What is antigen?An antigen is a substance that is capable of triggering an immune response in the body. It is typically a foreign substance, such as a pathogen (e.g. a virus or bacterium), a toxin, or a non-infectious particle (e.g. pollen or dust), that is recognized by the immune system as being foreign and potentially harmful.
When an antigen enters the body, it is recognized by immune cells called B cells and T cells, which produce proteins called antibodies to help neutralize and remove the antigen. The antigen-antibody interaction is a key part of the body's immune response and helps to protect us against infectious diseases.
Antigens can also be present on the surface of our own cells, such as cancer cells or transplanted organs, and can trigger an immune response if they are recognized as foreign by the immune system.
Overall, antigens are important components of the body's immune system and play a critical role in protecting us against infectious diseases and other threats.

Answer:
Where are the answers?
Explanation:
Answer: Earths orbit around the sun, solar energy, and volcanic eruptions
Explanation:
Earths orbit: At other times, the ellipse is more pronounced, so that the Earth moves closer and further away from the Sun in its orbit. When the Earth is closer to the Sun, our climate is warmer and this cycle also affects the length of the seasons.
Solar energy: Solar produces less life-cycle GHG emissions than conventional fossil fuel energy sources.
Volcanic eruptions: Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.

in phantom limb syndrome, which sensory pathway is responsible for conveying the sensory neuron activities?
Answers
The experience of the phantom limb syndrome involves the subjective sensation of the patient, the processes involved in this sensation are: both sensitive activity and the motor pathway.
The somatic nervous system is made up of mixed nerves (mixtures of sensory and motor axons) that emerge from the central nervous system, innervate the somatic effectors (skeletal muscles).Somatic motor pathways begin in the motor areas of the cerebral cortex, the projection neurons in that cortex emit axons that descend through the brain stem until they reach the spinal cord.Patients with this syndrome experience the sensation that the amputated limb is still attached to their body, since the brain continues to receive messages from the nerves that originally carried the impulses from the lost limb.Therefore, we can conclude that Phantom Limb Syndrome is the perception of sensations, which include pain of an amputated limb, where both sensory activity and the motor pathway have an action on said sensations.

D. Design a device that can throw an object at least 15 meters.
Explanation:
First of all, the object shown as you may be able to tell, look like a catapult. It also shows the top end of it holding a ball, getting ready to launch it. It then shows a line of the ball traveling after being launched. The balls land of the ground at 15 meters. From this iformation you look at the options:
A. Design an object that is 10 meters tall.
No, because 10 meter is just the highest point of the ball being launched.
B. Design a vehicle that can travel across a 10-meter feild.
No, because it is the ball that is traveling, not the catapult.
C is about a vehicle traveling again, so eliminate that too.
D. Design a device that can throw an object at least 15 meters.
