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!

Analyze the effects of DNA mutations
on the
of an organism.
Answer:
DNA mutations or Chromosomal mutations are also called chromosomal aberrations, chromosomal abnormality, or chromosomal disorders, all indicating a possible alteration in the morphology and structure of the chromosome.
DNA mutations lead to abnormalities in the function of the cell and organism, as chromosomal or DNA mutations can result in abnormal gene numbers or positions.
These are known to cause different genetic diseases that can be hereditary and are transferred from one generation to another.
These mutations, however, do not always affect the functioning of the cell as some mutations might affect regions of chromosomes that do not make up the genetic makeup of the organism.
Even though gene mutations are usually more severe than chromosomal mutations, some chromosomal mutations might result in gene mutations.

They change the color of the water and reduce aquatic photosynthesis.
A) They cause algae to reproduce rapidly causing algae blooms.

that a carrier mom and a black-eyed dad will have (hint: you must use X's and Y's):
a. a red eye male as their next offspring?
b. a black eye female as their next offspring?
2.
3
4.
5 6 7 8 9 10
Answer:
The correct answer is -
a. a red-eye male as their next offspring? = 25%
b. a black eye female as their next offspring? = 25%
Explanation:
The given question says that in flies the red eye color is a sex-linked recessive trait which means it will only appear in the presence of two copies of the recessive allele in females and one copy of recessive allele in male as there is only one copy of X chromosome is present in males the other chromosome is Y.
So, the genotype of carrier mom would be XaXA and normal black eye male would be XAY, then cross between these flies:
XA Y
Xa XaXA XaY
XA XAXA XAY
On the basis of red eye male would be XaY = 1/4 = 25%
and the black eye female would be XAXA = 1/4 = 25%

How does acid rain (deposition) form and travel to effect the environment?
Answer:
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes
Explanation:
DNA is wrapped around
and condensed into chromosomes.
• Genes are used as a set of instructions to produce proteins.
Proteins affect the
and function of organisms.
Chromosome
Answer:
- DNA is wrapped around nucleosomes and condensed into chromosomes.
- Proteins affect the traits and function of organisms.
Explanation:
Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.

6. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide. The enzyme increases the rate of reaction, so it is 700 times faster. If the enzyme reaction took 1.9s how long would the reaction take if there was no enzyme? Convert the answer to minutes. Give your answer to 4sf.
Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.
