Question 4 (3 points)

Simple diffusion and facilitated diffusion are related in that both require protein carriers A. depend on a concentration gradie

vodomira [7]

Answer:

A. depend on a concentration gradient

Explanation:

Simple and facilitated diffusion are the two methods of transport of substances down their concentration gradient. In both processes, substances are moved from the region of their higher concentration to that of their lower concentration. Since simple diffusion and facilitated diffusion are passive processes, there is no requirement of energy input to drive them. Both are driven by the concentration gradient of the substances only.

Which of the following is correct concerning the Km of an enzyme?

blsea [12.9K]

Correct answer is
D.it is the substrate concentration at which the velocity of the reaction is equal to 1/2 Vmax

What are some characteristics of the marine biome? Please help!

grigory [225]

Answer:

marine biome abiotic and biotic features. The abiotic features in the marine biome is the sunlight the water/ocean ,salinity, acidity, oxygen, light levels, depth, and temperature because its not living. some fects about the marine biome, Reef fish and coral off Eniwetok atoll in central Pacific.

Properties of Ocean Water. Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity.

Explanation:

marine biome-The marine biome is an environment characterized by the presence of salt water. The marine biome is found in all of Earth's oceans and is the largest biome in the world. The marine biome is home to an amazing array of living organisms, from the enormous blue whale to microscopic cyanobacteria.

Here are just a few of the animals that you will find in the marine biome:

Fish - Sharks, swordfish, tuna, clown fish, grouper, stingray, flatfish, eels, rockfish, seahorse, sunfish mola, and gars.

Marine mammals - Blue whales, seals, walruses, dolphins, manatees, and otters.

Which is the least number of seismograph stations needed to locate the epicenter of a earthquake

Hunter-Best [27]

At least three seismograph stations are needed to locate the epicenter of a earthquake.

Further Explanation:

An earthquake occurs when two region of the earth slip past each other. Fault plane is the area where the slip occurs. Hypocenter is the region below the earth’s surface where earthquake starts while the epicenter is the region above it.

The earth consists of four major layer:

1. Inner core

2. Outer core

3. Mantle

4. Crust

Seismographs is an instrument used to record the earthquake. The recording done by this instrument is called as the seismograms.

The seismograph comprises of:

1. A base: is fixed tightly in the ground

2. Heavy weight: hangs freely

When the earthquake occurs, the ground shakes and in turn the seismograph also shakes while the hanging weight does not shakes. During the earthquake, the difference in the location between the shaking piece and the motionless piece is recorded. Magnitude of the earthquake is recorded as one for each earthquake. The magnitude of earthquake is measured by the Richter scale but is more commonly measured through moment magnitude scale.
