Answer:
Option A, B, C
Explanation:
The major advantages of multienzyme complex over a metabolic pathway is that it do not require individual pathway for each enzyme activation or inhibition. Instead it responds efficiently to the equilibrium changes of substrate supply and demand as compared to that of enzymes.
It tightly regulates the processes and is also faster than that of the metabolic pathway.
Hence, option A, B and C are correct
In 1929, Edwin Hubble observed the velocity at which galaxies were moving away from the Milky Way. The graph below shows the relationship between this velocity and the distance those galaxies were from the Milky Way.
What conclusion can be drawn from Hubble’s data?
Objects that are closer are moving slower, suggesting that the Universe is shrinking.
Objects that are closer are moving faster, suggesting that the Universe is expanding.

leaves of cactus are modified into thorns
Answer:
To reduce loss of water through transpiration leaves of cactus plants are modified into spines.
Explanation:
Answer:
leaves are reduced to spines in a cactus , so that the water does not get evaporated with the heat of the SUN. 1. They are present in hot deserts which are scarce in water so in order to reduce the loss of water by Transpiration from the surface of the leaves, its leaves are reduced to spines
?Which form of energy is NOT correctly associated with the related example
kinetic energy: fat molecules O
potential energy: water held behind a dam o
kinetic energy: movement of muscles
chemical energy: glucose o
Answer:
kinetic energy: fat molecules
Explanation:
Fats store energy so it would be potential.
Kinetic energy: fat molecules
Kinetic energy is the energy that an object or particle uses during its motion. Potential energy is the stored form of energy already present in the object or particle. Chemical energy is the energy stored in the bonds of chemical substances. Water held behind the dam will have potential energy the water currents store energy within them which can be used to move the turbine in the water dam to produce electrical energy. Movement of muscles during walking, running, or performing any other activity which can be seen in the form of displacement from one region to another is due to kinetic energy. Glucose is a chemical molecule whose bonds when broken releases energy in the form of ATP or adenosine triphosphate which is a chemical energy. Fat molecules store energy in the adipocytes in the form of potential energy not kinetic energy. Hence, option kinetic energy: fat molecule is incorrect.Learn more about kinetic energy:

Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules.
Answer: Ribosomal RNA, Transfer RNA, and Regulatory RNAs.
Explanation: The introns do not code for any protein and are removed from the mRNA before it is made into protein.

O C. It's running out of water.
D. It has enough water to last 6,000 years.
Mark for review (Will be highlighted on the review page)
<< Previous Question
Next Question >>
Answer:
C!!
Explanation:
It's not B because it's located in the great plains. Not D because in 50 years, 70% of the aquifer will be gone. Not A because water use isn't regulated.
Ogallala Aquifer is the rock holding the groundwater in the Great Plains of America. The Ogallala Aquifer is running out of water. Thus, option C is correct.
What is Ogallala Aquifer?Ogallala Aquifer is an underground layer of water that is held by the rocks, pebbles, and gravel that make the water well above the surface. It is not beneath the East Coast but is situated on the Great Plains of the United States.
It has been reported that the water usage of the Ogallala Aquifer is not regulated and hence it does not have enough water to last up to 6,000 years. At approx 70%, the water of the aquifer will be soon gone resulting in the deprivation of the water.
Therefore, option C. the Ogallala Aquifer is running out of water is correct.

There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiply the series of dilutions together to find the final dilution value. If 6 serial dilutions are performed, each with a dilution of 0.1, what is the cumulative dilution
Answer:
cumulative dilution = 0.000001
Explanation:
A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.
The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:
Cumulative dilution = (F)ⁿ
where:
F = dilution factor = 0.1
n = number of serial dilutions = 6
∴ cumulative dilution = (0.1)⁶ = 0.000001

What is the wavelength of an X-ray whose frequency is 2.0 × 1018 Hz? Hint: An X-ray is an electromagnetic wave, so its velocity is equal to the speed of light (3.0 × 108 m/s).
A.
1.5 × 10-10 m
B.
3.0 × 10-8 m
C.
6.0 × 10-9 m
D.
0.6 × 10-11 m
Answer:
A. 1.5 × 10-10 m
Explanation:
Given the following data;
Frequency = 2.0 × 10^18 Hertz.
Speed of light = 3.0 × 10^8 m/s
To find the wavelength;
Wavelength = speed/frequency
Substituting into the equation, we have;
Wavelength = 3.0 × 10^8/2.0 × 10^18
Wavelength = 1.5 × 10-10 meters.

Plants have specialized cells that produce strong odors to attract insects.
Example:- The inflorescence of the titan arum plant attracts specific pollinators by emitting an intense, carrion‑like odor.Why plants attract insects?Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves.Flowers attract insect for pollination too.

How is cellular respiration and photosynthesis linked to specific organelles within the eukaryotic cells?
Answer:
Respiration. The energy collected in the chloroplasts is used during cellular respiration. ... The carbon dioxide and water produced are transferred back to the chloroplast where they are again used for photosynthesis. Cellular respiration takes place in another organelle called the mitochondria.
Explanation:
The mitochondria and cytoplasm is responsible for cellular respiration and the chloroplast is responsible for pjotosynthesis. Scientists theorize that mitochondria were once bateria themselves since they have their own Dna. They incorporated themselves into our cells to help us make energy. The chloroplast uses sunlight to break the hydrogen off the water and use the hydrogen to transfer electrons.
