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).

Consider the following food chain: Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes. In the short term, what will happen to the other members of the food chain if the mice were removed?
a.
the number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease
b.
the number of plants will decrease, the number of grasshoppers will decrease, the number of snakes will decrease
c.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will decrease
d.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will increase
Answer:
The answer is A
Explanation:
The number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease.
What is Food chain?Everything that is alive, from microscopic algae to enormous blue whales, depends on food to thrive. Each food web represents a possible route for nutrients and energy to travel through the ecosystem.
As an illustration, grass makes its own sustenance from sunshine. A bunny consumes some grass. Eaten by a fox, the rabbit. When a fox dies, microbes decompose its remains and return it to the soil, where it feeds grass-like plants.
Grass is consumed by a wide variety of animals, and rabbits can also consume other plants besides grass. Foxes can consume a wide variety of animals and plants. These living organisms can all be found in different food chains.
Therefore, The number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease.

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
Answer:
Color variations were already present in living moths.
Explanation:
Trust (hopefully)
Some species of hares are brown most of the year, but change color to white in the winter. This allows them to blend in
through the seasons.

how does a tape worm feed
Answer:
The tapeworm feeds off the food that the host is digesting.
Explanation:
Tapeworms get into the body when a person eats or drinks something that's infected with a worm or its eggs. Once inside the body, the tapeworm head attaches to the inner wall of the intestines.
Answer:
Tapeworms do not have a digestive tract. Instead, they absorb their nutrients from the gut contents of the host directly through their outside surface, tegument. New proglottids are constantly formed in the neck of the worm and along the length of the tapeworm they mature.

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.[
Explain in your own words why a fulcrum is necessary for a lever to work.
Answer:
The lever has two important parts. The lever itself and the fulcrum. The placement of the fulcrum determines how far the levered object will move, and how much force is required to move it. If a weight was resting on a lever a person could lift the weight by pressing on the lever on the other side.
