What statement about enzymes and pH is true?
A Most enzymes require a very acidic environment to function well.
B Most enzymes require a very basic environment to function well.
C Enzymes are unaffected by changes in pH levels.
D Enzymes require a specific range of pH values to function.
Answer:
D. Enzymes require a specific range of pH values to function.
Explanation:
Enzymes function the best in a neutral pH, rather than in very acidic or basic environments.
Enzymes are very affected by changes in pH levels because they perform much better in neutral environments.
Why Kiwi(Bird in NZ) doesn't fly?
Answer:
Their wings are vestigial, as the kiwi birds are descended from flying ancestors.
Explanation:
Their pectoral muscles are not anchored to the breast bone in a way that enables them to fly, and their wings are very small and underdeveloped meaning they wouldnt be able to gain lift with them.

Which of the following bonds is an attraction between atoms of different molecules?
Answer:
pretty sure its covalent bond
Explanation:
stion 6/48which would be the best evidence that a cell is using active transport to move a substance across its cell
membrane?
A) Substances are moving rapidly across the cell membrane.
B) ATP is being rapidly consumed near the cellular membrane.
C) Substances are moving from high to low concentrations.
D) Substances are moving through channels in the cell membrane.
Answer:
B) ATP is being rapidly consumed near the cellular membrane.
Explanation:
Active transport is a form of transport used by living systems in which substances/molecules move across a membrane from a region where they are less concentrated to a region where they are highly concentrated. This movement occurs against the concentration gradient, hence it requires energy in form of ATP in order to occur. The transport is said to be "ACTIVE" if it is energy consuming.
Hence, based on the explanation above, the best evidence to showcase the occurrence of active transport in a cell is the rapid consumption of ATP near the cellular membrane. ATP will be used to pump needed substances into the cell via the cell membrane, serving as the semi-permeable membrane.

This area is shows Minnesota to Lake Michigan, which is the largest body of water shown. The upper right red circle is the closest circle to Lake Michigan. As weather is deeply linked to weather systems, the area closest to a large body of water will experience the most devastating effects.
Which feature is not the result of a glacier carving out rock as it moves?
A. Cirque
B. Terminal moraine
C. Fjord
D. Horn peak
Answer:
B. Terminal moraine
Explanation:
Terminal moraine forms at the end of a glacier due to contact abrasive action of the rocks. The glacier carving out rock as it moves doesn’t occur in the terminal moraine.
The Cirque, Horn peak and Fjord are all processes characterized by the glaciers carving out rocks as they are moved by elements such as wind and water.
The cytoskeleton in a cell is responsible for which?
Answer:
C the specific shapes of bacteria
Explanation:
It is responsible for sustaining a cell's shape, for the locomotion of a cell, and for the movement of the various organelles within the cell itself. Besides the intracellular movement of organelles, the cytoskeleton is responsible for chromosome movement during cell division and for cytokinesis.

An object of the same mass has three different weights at different times. Which statement is possible? The object gains matter and then loses it. The object started on Earth, was transported to space, and was deposited on the moon. The object started at the bottom of a hill, then moved to the top of the hill, and then moved back down to the bottom of the hill. The object changes shape, which changes its weight.
Explanation:
Hey, there!!
The possible reason is option no. b.
Because
for the first option its absolutely wrong. For the second option there is variation of gravity in different places so, the weight differes. (as w= m.g)For the third option, the weight changes when the object is kept at top at once and low at once but for the third time again the object is replaced at same place. so, it only gives two different weights.4th option is incorrect.so, i think the answer is option B.

What kingdoms of life can have either sexual or asexual reproduction
Answer:
Protista, Fungi, and Plantae.
Explanation:
PROTISTA - asexually with binary fission , and sexually; two individuals join and exchange genetic material in the nucleus.
FUNGI - Reproduce sexually and asexually.
PLANTAE - Sexual reproduction involves the male pollen grains traveling to the stigma of a flower , and asexual reproduction involves the production of a new plant without the use of flowers.

After getting the slide and microscope ready, Stella is eager to see the microscopic pond
water specimen! She crouches around her microscope and aligns her eye with the
microscope's eyepiece. But she's only able to see a bright white light.
At this point, no specimens or cells are visible on Stella's pond water slide. After taking a
moment to collect her thoughts, Stella realizes she can't see any lifeforms because
Answer:
the microscope is not in focus
Explanation:
Stella was only able to see white light through the eyepiece because the microscope is not in focus. She is supposed to bring the microscope into focus by using the coarse adjustment knob in conjunction with the fine adjustment knob. Both knobs are adjusted till the specimens or cells in the pond water present on the slide become visible through the microscope's eyepiece.

Does anyone know this this animal is. my Francis is a praying mantis but I’m not sure
You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes
Answer:
C. Phenotypes
Explanation:
Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.
Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.
So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.
Hence, the correct option is "C. phenotypes".

After winning power, the Jacobins sought strong leadership to face overwhelming challenges by deciding to form the Committee of Public Safety.
What is the Committee of Public Safety?It should be developed by the National Convention in the year 1793 for defending the nation that should be against the foreign and the domestic enemies.
Also, it oversees the new functions of the executive government.
Therefore, we can say that it helped to decide to create the Committee of Public Safety.

Explanation:lo que dice ahi neta que si
Answer:
Taxonomy
Explanation:
Prior to being able to sequence DNA, organisms were described and categorized solely by their distinct morphologies (physical characteristics) and ecological roles. The ability to sequence DNA has revealed a great deal more about where an organism belongs taxonomically and helps pinpoint new species. DNA is now used alongside morphology and ecology to substantiate an organism’s distinctiveness in the biological world.
