Lamarck's ideas about evolution include the concept that differences among the traits of
organisms arise as a result of
O continual increases in population size.
the actions of organisms as they use or fail to use body structures.
an unchanging local environment.
the natural variations already present within the population of organisms.
According to Lamark's theory of evolution, differences among the traits of
organisms arise as a result of the actions of organisms as they use or fail to use body structures.
The theories of evolution try to explain the changes that occur in living things as new species replace existing ones. There have been two main theories that seek to explain the evolution of organisms'
Darwin's theoryLamark's theoryThe theory of Lamark deals with use and disuse of body parts. Body parts that are not used begin to degenerate and only appear as relics in new species. A typical example of this is the appendix in humans. Hence, according to Lamark, differences among the traits of organisms arise as a result of the actions of organisms as they use or fail to use body structures.

The letters that make up the genetic code of DNA
Answer:A, C, G, and T are the "letters" of the DNA code; they stand for the chemicals adenine (A), cytosine (C), guanine (G), and thymine (T), respectively, that make up the nucleotide bases of DNA.

Transcribe this sequence of DNA to RNA: ATTGAC
Answer:
your can write fast summary about it if you have test or smth
First, think about which base pairs arise in complementary strands of DNA:
DNA → DNA
adenine → thymine (A → T)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.
So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.
DNA → RNA
adenine → uracil (A → U)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
Giving us the corresponding sequence:
UAGGCUAA

How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.

.What might happen to cells with DNA that has been damaged by an environmental influence such as UV light from the sun or a tanning bed?
Answer:
It can lead to melanoma or a time of skin cancer.
Explanation:
This is because UV radiation in sunlight can destroy the DNA by destroying the base pairing. UV light will cause two Thymine that are very closer to each other to join together to produce dimer. After which, The melanin-assisted process form lesions that is popularly called cylobutane pyrimidine dimers in DNA, which can result in mutations that cause melanoma which is a form of skin cancer

What is the complementary sequence of DNA to this DNA strand?
Original DNA Strand: TGACGGTA
C matches with G and A matches with T, so:
TGACGGTA
matches with
ACTGCCAT
Answer:
ACTGCCAT
Explanation:
complementary means you can form a double- stranded structure by matching base pairs.
In this case we have TGACGGTA and the matching pairs are ACTGCCAT.
If a widow’s peak (W) is controlled by a dominant allele and a straight hairline (w) is controlled by a recessive allele, how would you describe a person whose genotype is Ww?
Answer:
The correct answer is - a heterozygous individual with widow's peak.
Explanation:
In the given case, the dominant character is the widow's peak that is represented by the allele W and the straight hairline is a recessive character represented by the allele w. So, if an individual has both dominant alleles WW it means this individual has widows peek as W is the dominant allele and if this individual has ww allele it means the straight is expressed as no dominant allele to mask the effect of recessive allele w.
In the case of heterozygous that means one copy of dominant and one copy of recessive allele is present that is Ww then this individual have a widow's peak due to the fact that dominant allele will mask the effect of recessive allele.

Answer:
A.glassy sweeper and squirrelfish
Explanation:
I took this test already and got that question correct
Glassy sweeper and squirrelfish are two fishes that have eyes located on either side of their head and are not spotted. Hence, option A is correct.
What is the dichotomous key to identifying fish?Making use of a dichotomous key is one method of fish identification. These keys use a sequence of paired (two) choices based on an organism's physical traits to exclude potential candidates for the organism's identity.
The shape of fish's heads, the location of their mouths, the type and location of their fins, and their average adult size are some traits that set them apart.
When combined with other characteristics like geographic range, color patterns like vertical stripes or fin patches may also aid in differentiating fish. Hence, option A is correct.
