A. metamorphis
B. pupae stage
C)simple life cycle
Question 2
A)breathes through lungs
B. forms a pupa
C. lives completely underwater
The correct answers are A A.
Explanation:
Salamander go through process of metamorphosis that reproductive changes. They have a larvae stage that breathe through gills because the larvae are inform of a fish and gave gills for respiration while the adults breaths through lungs. The larvae stage develops 30 days after hatching and can possibly change into an adult like 60 after hatching.
Answer:
metamorphosis
Breathes through its lungs

Explain how cellular respiration is important for the production of ATP build on aerobic vs anaerobic
Answer and Explanation:
ATP is the energy molecule of the organism, being necessary for all cellular processes. It is produced in both aerobic and anaerobic respiration, but the processes are different.
Aerobic respiration, ATP is produced by breaking down the glucose molecule found in the food we consume. This process occurs in all organisms that need the presence of oxygen to survive. However, this is a complex process that occurs with the help of several enzymes and co-enzymes that perform various oxidation reactions on the glucose molecule, transforming it into carbon dioxide, water and ATP.
Anaerobic respiration is also known as fermentation and occurs in all organisms that cannot survive in the presence of oxygen. This process also occurs with the help of enzymes and coezimas, where the glucose molecule is degraded until it becomes two molecules of pyruvate. During the pyruvate degradation reactions, an ADP molecule is released, which will later be added to a phosphate molecule that is free in the cytosol, becoming ATP.
Cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. Only list the phenotypic ratio at the end.
Answer:
The phenotypic ratio is 9:3:3:1
9/16 individuals with axial flowers and rounded fruits, R-A-3/16 individuals with terminal flowers and rounded seeds, R-aa3/16 individuals with axial flowers and wrinkled seeds, rrA-1/16 individuals with terminal flowers and wrinkled seeds, rraaExplanation:
We need to cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. When referring to a hybrid plant for a trait, we are meaning that the plant is heterozygous for that trait.
Let us assume that round is the dominant trait, codified by a diallelic gene, so
R is the dominant alleler is the recessive alleleLet us also assume that axial is the dominant trait, so
A is the dominant allelea is the recessive alleleCross:
Parentals) RrAa x RrAa
Gametes) RA, Ra, rA, ra

Why do cells need to undergo meiosis
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins following one round of DNA replication in cells in the male or female sex organs.

How is a warm front different from a cold front?
Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather.
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.
Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.
Answer:
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Explanation:
i'm pretty sure
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather. So, the correct option is B.
What are Warm and cold fronts?A warm front forms when a mass of warm air enters a space that previously held cold air. As warm air passes over cooler air, it rises and cools, which can result in the formation of clouds and precipitation. Unlike a cold front, a warm front often brings with it lighter and more widespread precipitation. Warm fronts often bring warm temperatures and high humidity levels.
When a mass of cold air approaches an area that was previously surrounded by warm air, a cold front is formed. When cold air flows into warm air, the warm air is forced to rise rapidly, which can result in thunderstorms and heavy rainfall. More extreme weather changes, such as a sharp drop in temperature and drop in humidity, are often brought about by cold fronts.
So, the correct option is B.

If the carrot population increased, the rabbit population would:
NO LINK ANSWERS
A. increase
B. decrease
C. remain the same
Answer:
The rabbit population would remain the same as the increase in number of carrots doesn't determine / effect the population of rabbits.
Hope my answer helps !
Answer:
i believe the answer is c) remain the same
Explanation:
i say this because food availability wouldn't necessarily cause the population to grow (there would need to be an environmental change for this to happen.)
and the population wouldn't decrease because there would be an abundance of food and since starvation is one of the main causes of population decrease (along with over-crowding.)
good luck :)

Why might scientists be interested in using algae for biofuel production?
Answer:
Algae actively absorb carbon dioxide, and therefore reduce the greenhouse effect. Fuel from microalgae is called third-generation biofuel, and development for its production is currently underway. With sufficient information on the composition of biofuels, researchers can significantly improve production processes.

Shawn explains that many studies have shown that directly spraying bees with fungicides doesn't harm them. Are those results consistent with what Shawn has discovered? Explain your answer in a few sentences.
Answer:
Yes.
Explanation:
Yes, the results will be consistent of spraying bees with fungicides because the fungicides affect the growth of fungus not the bees. fungicides are the chemicals kills fungal growth while on the other hand, insecticides will kill the insects such as ants, bees etc. If the Shawn apply insecticide on the bees, it will kill the bees due to its effectiveness so that's why the results of the directly spraying bees with fungicides will always be consistent due to its ineffectiveness.

Why are organisms in lower parts of the food chain not affected but organisms at the top of the food chain are?
Answer:
the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.
Explanation:
Answer:
The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!
