Why is adequate lighting necessary in a balanced aquarium?

Biology

Answer:

A. Fish need light to see their food

Explanation:

B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.

C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)

D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.

A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

Hope this helped!

Advantages of constant body temperaure

Leya [2.2K]

Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life.

Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm.

The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size.

The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.

When does the nuclear membrane dissolve? When does it reform?

Setler79 [48]

Answer:

prophase

Explanation:

Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.

strojnjashka [21]

Answer:

The question is incomplete, the complete question has been added as an attachment.

THE DGR AN represents deletion mutation

THE RED ANA TRA N represents insertion mutation

THE FOX WTS RED represents substitution mutation

Explanation:

Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.

An insertion mutation is the addition of one or more nucleotide bases to the sequence.

A substitution mutation is the replacement of one or more nucleotide base in a sequence.

The original sentences were:

1. THE RED ANT RAN

2. THE FOX WAS RED

3. THE DOG RAN

The three sentences that mutated/changed are:

1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.

2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.

3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.
