Which of the following best explains why animals that inhabit warmer regions tend to have smaller body sizes?
A higher surface-area-to-volume ratio facilitates heat loss.
Animals in warmer climates need to move more quickly to catch prey.
More species inhabit warm climates, and smaller size enables a greater number to live in the same ecosystem.
Smaller body size enables faster reproduction and repopulation to maintain a niche in overpopulated warmer climates.
Answer:
I believe it may be a higher surface area to volume ratio facilitates heat loss
Explanation:
Out of the options it makes the most sense being that larger animals keep heat in...

Why is the question what is an plane so difficult to answer
Answer:
Look below - A plane is math related.
Explanation:
a flat surface on which a straight line joining any two points on it would wholly lie.
"the horizontal plane"
synonyms:
flat surface · level surface · the flat · horizontal
Hope this Helps!
Answer:
I Don't Know what your asking but if your trying to figure out what a plane is this might help
1. a flat surface on which a straight line joining any two points on it would wholly lie.
2. a level of existence, thought, or development.
3. completely level or flat.
4. (of a bird or an airborne object) soar without moving the wings; glide.
Also I don't know why this would be biology related.

Question 12 When cells get energy from glucose without oxygen it is called fermentation, cytoplasm, photosynthesis, phosporolation
Answer:
fermentation
Explanation:
Glycolysis is an ancient, major ATP-producing pathway that occurs in almost all cells, eukaryotes and prokaryotes alike. This process, which is also known as fermentation, takes place in the cytoplasm and does not require oxygen.
What evidence is there that the 15 species of finch all evolved from one common ancestor?
All of them evolved from one rooted species, which colonized the islands only a few million years ago. This process, whereby species evolve rapidly to exploit empty eco-space, is known as adaptive radiation.
What is evidence of common ancestry and how do they explain evolution?Homologous structures provide proof for a common origin, while analogous structures show that similar selective pressures can produce similar adaptations. Alikenesses and differences among biological molecules can be used to determine species' relatedness.
Thus, adaptive radiation is one of the reasons.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.

PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.
Answer:
Autotroph
Explanation:
An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.
According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

Genetic mutations introduce new gene forms in a population. For instance, the mutation that affects
hemoglobin alters the shape of the red blood cell and makes it sickle-shaped. Which statement
below would explain why the sickle-cell mutation has spread through the gene pool?
A. There is a selective advantage to having Sickle Cell Anemia.
B. This kind of mutation demonstrates a common ancestor.
C. The sickle cell mutation has no benefit.
D. Sickle cell anemia increases the risk of death.
Answer:
B- this kind of mutation demonstrates a common ancestor.
Explanation:
in order to have sickle cell anemia you need to have both recessive alleles from both parents, this recessive allele has to be continuous passed down from generation to generation on both sides, which shows a common ancestor from long ago
Please help to solve this question.
Answer:
a. Glycolysis
b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration
c. Heart tissue!
Explanation:
a. Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.
b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.
c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.
