Answer:NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. ... An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water.

What type of contraction, concentric or eccentric, would cause more fatigue to occur in a muscle? Why?
Answer:
concentric
Explanation:
Eccentric contractions are lengthening movements of your muscles. During this muscle movement, your muscle fibers are stretched under tension from a force greater than the muscle generates. Unlike a concentric contraction, eccentric movements do not pull a joint in the direction of a muscle contraction.
Answer:
Eccentric contractions have recently shown to be caused greater low- frequency fatigue than concentric. This is because size of fall in the force from eccentric contractions carry out on fresh muscle is signifgantly larger. Explanation:

. Which waves cause the most movement of the rocks during an earthquake?
A. surface waves
B. S-waves
C. P-waves
Answer:
A
Explanation:
There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
why does the respiratory system require two organ systems
Answer:
The lungs expel the carbon dioxide and bring in new oxygen-containing air. Only when both systems are working together can oxygen and carbon dioxide be successfully exchanged between cells and environment. There are many other examples of this cooperation in your body. :)

if 40 carabaos live in a 4 sq. meter area,what is their population density per sq. km.?
Explanation:
Given parameters:
Number of carabaos = 40
Area of the place = 4m²
Unknown:
Population density = ?
Solution:
The population density of the place is the number of organisms per square km.
Mathematically;
Population density = [tex]\frac{number of Carabao}{Area}[/tex]
Population density = [tex]\frac{40}{4}[/tex] = 10carabaos/m²

If a cell was not able to produce enzymes, it could not do which of the following?
a) Raise the activation energy of vital chemical reactions, causing them to proceed too quickly
b) Lower the activation energy of vital chemical reactions, causing them to proceed too quickly
c) Raise the activation energy of vital chemical reactions, causing them to proceed too slowly
d) Lower the activation energy of vital chemical reactions, causing them to proceed too slowly
Answer:
Answer is D
Explanation:
Explanation:if your cell doesn’t produce enough enzymes it wouldn’t be available to speed up reactions throughout your body, and they would also not be available to make the many organelles made with proteins.

How are food webs different to food chains? Explain why foodwebs are more useful
Answer:
Explanation:
A food chain is different because it shows what organisms eat in a straight line, in a chain. For example, a bird of prey can eat a snake that previously had eaten a frog and the frog ate a grasshopper and so on. But this tells us very little. A foodweb will tell us how all those animals are connected and what they eat in a web, not just a line.
What dose the arrow mean in a food chain
Answer:
What eat next or what will turn into something next
Explanation:
Answer:
Arrow are used to show relationship between the organisms, things etc.

Which of the following is one of the ways that cellular respiration and photosynthesis are opposite processes?
A.)Photosynthesis releases energy, and cellular respiration stores energy
B.)Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
c.)Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it back,
d.) Photosynthesis consumes glucose, and cellular respiration produces glucose.
Answer:
B.)Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Explanation:
One of the ways in which photosynthesis differs from respiration is that photosynthesis removes carbon dioxide from the atmosphere and cellular respiration puts it back.
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight using carbon dioxide and water. The product is usually glucose and oxygen. Respiration breaks down energy rich compounds into ATP, carbon dioxide and water.State the Two stages of photosynthesis
Answer:
Light and Dark Reactions

what type of wave must have a medium to transfer energy
Answer:
Mechanical waves
Explanation:
Mechanical waves are waves that must have a medium to transfer energy. Without a medium, mechanical waves cannot be propagated in space.
Electromagnetic waves on the other hand do not require a material medium for their propagation. They can move energy through a vacuum. Examples of mechanical waves are sound waves, water waves, seismic waves etcExamples of electromagnetic waves are x-ray, infrared, light waves.Which two parts of the Earth make up the lithosphere? inner core and mantle? inner core and outer core? mantle and outer core? crust and outer part of the mantle?
