Two decades after the Emerald River Dam was built, none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.
Which of the following statements, if true, would most strengthen the scientists’ hypothesis?
(A) The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.
(B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish.
(C) The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees, whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.
(D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space.
(E) Five of the fish species native to the Emerald River are not native to any other river in North America.

D) Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains,
Answer:
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains.
Explanation:
took the test and got it correct
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. The correct option is D.
What are Eubacteria?Eubacteria are bacterial counterparts. They go under the name "real bacteria." They lack membrane-bound cell organelles and a genuine nucleus. These are single-celled, tiny creatures.
Contrary to appearances, Eubacteria and Archaebacteria (also known as Archaea) are divided into distinct realms of life based on variations in their genetic make-up, particularly in the sequences of their ribosomal RNA (rRNA).
Together with Eukarya, Eubacteria and Archaebacteria are currently acknowledged as distinct domains of life.
This classification represents the underlying biological differences between the two categories, including variations in cell walls, lipid membranes, and metabolic pathways.
Thus, the correct option is D.

How do buffers play a role in
homeostasis in living things?
Answer:
Buffers are commonly used in living organisms to help maintain a relatively stable pH.
In biological systems, chemical buffers prevent sharp and sudden changes in pH.
In biology, homeostasis refers to stable conditions required for the survival of organisms.The pH is a scale used to determine how acidic/basic water is. The pH range from 0 to 14 ( a pH equal to 7 is neutral).In human blood normal pH is about 7.35 to 7.45. A sudden change in this value alters and negatively affects the homeostasis of the body.The carbonic acid-bicarbonate is the most important chemical buffer which is used for mantaining acid-base balance (homeostasis) in the blood.The blood pH can change due to respiratory acidosis/alkalosis and metabolic acidosis/alkalosis.In conclusion, chemical buffers prevent sharp and sudden changes in pH.

Response
Explanation:
It is response because your pupils are responding to the light flashing in your eyes and therefore they get smaller.
Hope this helps :)
Answer:
Response
Explanation:
We can use process of elimination. Reproduction does not fit in this context--nothing is reproducing. Nothing is growing, either. Development usually refers to when an organism develops, which doesn't fit this context either. Response is the only one that fits--your pupils are responding to the sudden light.
The theory of evolution states: Question 5 options: better adapted organism reproduce at a higher rate organisms change by acquired characteristics organism populations can change physically over long periods of time modifications in an individual is caused by its environment none of the above
Answer:
The theory of evolution was proposed by Charles Darwin and was first formulated in his book, "Origin of Species" in 1859. It focuses on the changes in species and populations over time
A cell pumps hormones out into the bloodstream; a process that requires energy. If 4 ATP were converted to ADP, how much energy was used?
A. 4 kJ
B. 30.5 kJ
C. 122 kJ
D. 1600 kJ
It is 122KJ of energy is used from the conversion of ATP to ADP because hydrolyses of 1 mole of ATP requires 30.5KJ of energy. Therefore, if 4 ATP is hydrolyses, it will be 4× 30.5=122KJ. ... This energy is given out because there is cleavage of high energy phosphate bond in ATP while converting it into ADP.

What is mean by photosynthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Which of the following correctly describes Metaphase?
A. The Cytoplasm splits, forming two daughter cells
B. Centrioles move to opposite sides of the cell, nuclear envelop dissolves, chromosomes form
C. Chromosomes split and move to opposite sides of the cell, the cell elongates
D. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell
Answer:D
Explanation:
. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle.
In the metaphase, mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell. The correct option is D.
What are spindle fiber?Spindle fibers form a protein structure that divides a cell's genetic material. The spindle is required to split the chromosomes in a parental cell evenly into two daughter cells.
During metaphase, these spindle fiber gets attached to centromere of the chromosome and align the chromosome at the equator.
Long protein fibers known as microtubules prolong from the centrioles in all directions, forming a spindle. Some microtubules connect the poles to the chromosomes via protein complexes known as kinetochores.
Spindle fibers from the opposite side of the cell connect to the chromosome's both these sister chromatids.
They connect at the kinetochore, which comprises a disc or protein on each side of the centromere. The chromosomes will be moved by the spindle fibers until they are aligned at the spindle equator.
Thus, the correct option is D.
