The DNA code for normal hemoglobin contains the following segment:
TGC-GGA-CTC-CTC
Which of these is the m-RNA code for this segment of DNA?
A) UGC-GGA-CUC-CUC
B) ACG-CCU-GAG-GAG
ACG-CCT-GGA-GAA
D) TCC-GGT-CTC-CTC
The messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).
What is mRNA?The messenger RNA (mRNA) is a template created during transcription, which is used to generate a protein.
A specific fragment of DNA is used to create this template (mRNA) by transcription.In RNA, Thymine nucleotide bases are replaced by Uracil nucleotide bases.In conclusion, the messenger RNA (mRNA) code for this segment of the hemoglobin DNA gene is ACG-CCU-GAG-GAG (Option B is correct).

The peppered moth is a classic example of natural selection in the
environment. The peppered moth has three color patterns: light, medium,
and dark. Prior to the industrial revolution, the light moth, which could
better blend with the tree bark, was the most prevalent. After
industrialization, the darker moth population quickly increased since the
tree bark became darker. Which of the following BEST describes why the
change in population occurred so quickly?*
Mutations took place in DNA.
O Different species of moths interbred.
Industrialization took place in a short period of time.
O Color variations were already present in living moths

why do you think diversity is important for the survival of a species?
Answer:
Genetic diversity refers to the amount of genetic variation within a species. Diversity is important for species survival as it provides a way for populations to adapt to changing environments with more variation. More individuals within a population will possess allele variations that are suited to the environment and they will survive more effectively.

How are the smallest ocean waves produced?
A.Weak winds that blow for short periods of time over great distances.
B.Weak winds that blow for long periods of time over small distances.
C.Weak winds that blow for short periods of time over small distances
D.Weak winds that blow for a long time over a great distance.
Answer: the answer is C
Explanation:
Answer:
c!
Explanation:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

A)unaltered preservation
B)carbonization
C)casting
D)perimineralization
Answer:
D. Perimineralization
Explanation:
After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.

what is the smallest biological unit called
Answer:
A cell
Explanation:
Answer:
cell
Explanation:
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
In base pairing for the translation of DNA to mRNA, which nitrogen base complements Adenine?
Answer:
Adenine and thymine form base pairs that are held together by two bonds, while cytosine and guanine form base pairs that are held together by three bonds. Bases that bond together are known as complementary. During transcription, DNA is converted to messenger RNA (mRNA) by an enzyme called RNA polymerase.

Write 5-6 sentences about snakes. (This is for an informational paper, make if formal!) Please don't put links/files to download because I can't download on this computer since it is the family computer. THANK YOU!
Answer:
Hi, I can help you!
Explanation:
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[
Compared to a rounded particle with low density, a HIGH density,
rounded particle of the same size will sink through water
•more slowly
•at the same rate
•more rapidly
Answer:
more rapidly
Explanation:
Density of a substance refers to the mass of that substance in relation to one unit of its volume. The density of a substance is the basis of whether such substance will float or sink in a liquid. This means that if the density of an object is higher than that of a liquid medium e.g water, the object will SINK while if the density of the object is lower in relation to the liquid medium, the object will FLOAT.
According to this question involving a rounded particle. If the rounded particle is of low density than water, it will float. However, if the rounded particle of the same size is of HIGH density than water, it will SINK MORE RAPIDLY.

Explanation:
An open circulation the blood is not blood vessels, it instead is pumped into a cavity called Hemocoel.
A closed circulatory system, the blood is pumped through vessels SEPARATE from the interstitial fluid of the body.
How is a phylogenetic tree similar to a dichotomous key?

C) Both convey common ancestry from an originating organism.
D) Both map evolutionary processes from similar organisms.
A phylogenetic tree is similar to a dichotomous key because B. Both were founded by Carl Linneaus.
A phylogenetic tree is also called the phylogeny. It's a diagram that shows the evolutionary relationships that can be found in various organisms.
A dichotomous key refers to a scientific tool that's used in the identification of different organisms based on the observable traits that can be found in the organism.
