Identify the type of mutation that occurred in the sequence above and evaluate the significance of these changes. (Will it have any problems in protein synthesis?)
Hint: 1st determine if it was copied to mRNA correctly. When you find the error, that is the mutation. 2nd use the chart if a different amino acid is created, this will determine if it will affect protein synthesis.
Answer:
See the answer below.
Explanation:
The correct mRNA sequence from the DNA according to the base pairing rule should be:
AAU GCG UUG ACC GAU UAA
Instead of:
AAU GCG UGA CCG AUU AAC
This thus means that some of the nucleotide bases have been wrongly substituted.
The most important change is the codon 'UUG' becoming 'UGA', while the former codes for the amino acid leucine, the latter represents a stop codon. A stop codon will result in a non-functional or defective protein.
Hence, the type of mutation is nonsense mutation which results in a sudden cessation of protein synthesis as a result of a codon being prematurely changed to a stop codon.
The significance of this kind of mutation is that a defective on non-functional protein will result which will have a serious phenotypic implication in organisms.

What are chromosomes?
Answer:
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Chromosomes are structures formed by a DNA molecule associated with protein molecules. In prokaryotic cells, we observe a circular chromosome; in eukaryotes, chromosomes are linear and located inside the nucleus.

What is circulatory system ?A circulatory system is defined as a system in the body that consists heart, blood vessels, arteries, veins and blood that all combined together to supply blood to all parts of body and takes up waste material from it.
Circulatory system have four major components and these are heart, veins, arteries, and blood. These are the four components that combined and form cardiovascular system.
Pulse rate or heart rate is the speed of heart beat measured number of contraction of the heart per minute. The heart rate can vary according to physical needs of human beings. If a person done a physical activity then it's need more blood circulation then pulse rate increases.
The normal pulse rate or heart rate is 60-100 bpm, but when a person is sleeping their pulse rate became 40-60 bpm.

A. An experience or period in the author’s life.
Explanation:
A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.
Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.
Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.

sedimentation
Which of the following can be determined based on this model?
A.
The atmosphere is the only reservoir on Earth that can store carbon in any form.
B.
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration.
C.
Dead organisms and waste products do not play any role within the carbon cycle.
Factories do not emit any amount of carbon dioxide into the atmosphere.
Answer: The answer would be B
Explanation: All plants and animals release at least some amount of co2 into the atmosphere during cellular respiration
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration can be determined based on the Carbon cycle model. So, the correct option is B.
What is Carbon cycle?The exchange and recycling of carbon in the Earth's biosphere, lithosphere, hydrosphere and atmosphere is known as the carbon cycle. All living things contain the element carbon, which is also an important component of many important compounds such as proteins, lipids, and carbohydrates.
Photosynthesis, respiration, combustion and weathering are just a few of the different processes that make up the carbon cycle. Plants use photosynthesis to take up atmospheric carbon dioxide and convert it into organic molecules. Plants and other organisms then use these molecules as a source of energy.
Therefore, the correct option is B.

Describe step by step, with your own words, the process of replication of a double strand of DNA.
Answer:
replication. DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

which is not an example of inorganic fertilizer? A.nitrogen fertilizer B.phosphorus fertilizer C. Livestock waste
Answer:
Livestock waste
Explanation:
Fertilizers supplement the soil with macronutrients needed in large amounts: nitrogen, phosphorous and potassium. However, organic and inorganic fertilizers do so via different materials. Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost.
Inorganic fertilizer, also referred to as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals. For example, synthetic nitrogen fertilizers are typically made from petroleum or natural gas. Phosphorus, potassium and other trace elements in inorganic fertilizers are often mined from the earth. Balanced inorganic fertilizers, high in all three macronutrients, commonly include products like ammonium nitrate, ammonium sulfate, potassium chloride (potash), triple superphosphate, and magnesium sulfate (Epsom salts).

f. improved air quality in urban areas
thanks!
Answer:
a. more stable weather conditions --- NE
b. more wheat and less canola grown as crops ---E
c. greater threat to forests from insect pests ----E
d. greater biodiversity of wetland species ----E
e. better agricultural conditions in northern Alberta ----E
f. improved air quality in urban areas-----NE
Explanation:
The climate of Alberto change with the increase in temperature which disturb the weather condition of the region. This increase in temperature decreases the production of wheat crop so more wheat crop is cultivated for fulfilling the needs. This increase in temperature make the environment more suitable for different organisms. The climate is cold during winter so increase in temperature causes condition suitable for agriculture in northern Alberta. Improved air quality in urban areas is not possible due to more production of carbondioxide gas which leads to increase in temperature.

why are there no small organisms in the bathyal zone?
I will give 50 extra points if you are correct!!
Answer:
There are no known organisms because of the lack of sunlight necessary for photosynthesis to produce these organisms
Explanation:
The bathyal zone is less densely populated. Sunlight does not reach this zone, meaning primary production, if any, is almost nonexistent
