Carbon ______________ are processes that add carbon to the atmosphere. Carbon ______________ are processes that absorb carbon
Answers
Answer:
Carbon sources
Carbon sequestration
Explanation:
Carbon sources are regions that produces atmospheric carbon dioxide. This carbon dioxide is naturally added to the atmosphere when organisms respire, decompose, rocks with carbonate are weathered and volcanoes erupt.
Carbon sequestration is the process of taken and storing atmospheric carbon dioxide. The method helps in reducing the amount of carbon dioxide in the atmosphere which in turn reduces global climate change.

Albinism results from mutations in an individual's DNA. Explain how that ultimately results in an non-functional protein. Use all of the terms from your flowchart above in your explanation. Also include locations and any enzymes involved. **TERMS USED: "transcription, translation, amino acid(s), protein, gene, mRNA, tRNA, trait "
Answers
Answer:
Please find the explanation below
Explanation:
Albinism which is a condition characterized by the lack of skin pigment is caused by a mutation in the nucleotide sequence that encodes the melanin protein. However, this mutated gene undergoes TRANSCRIPTION into a mutated mRNA sequence, and subsequently undergoes TRANSLATION into a mutated amino acid sequence.
The amino acid sequence results in a non-functional protein as the nucleotide sequence of the original DNA has been altered. This non-functionality of the mutated protein results in ALBINISM TRAIT.

Previous studies have shown th gene X is never expressed in nerve cells. Based on the diagram, which of the following most likely contributes to the specific expression pattern of gene X?
A.Expression of gene X produces large amounts of tRNA but undetectable amounts of mRNA.
B The general transcription factors inhibit the activation of gene X in liver cells by blocking the activator from binding to RNA polymerase II.
С The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues.
D The enhancer is a unique DNA segment that is added to the nuclear DNA of some cells of an organism during the process of mitotic cell division but not other cells.

What is gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Because a particular protein can only be made when its gene is turned on, gene expression is significant.
However, there are several steps involved in translating a gene into a protein, and one of these steps—the creation of proteins—is crucial in the gene expression pathway that can be changed in cancer.
According to the diagram, the activator is a DNA-binding protein that only binds to certain sequences in select tissues.
Thus, the correct option is C.

Answers
Answer:
Chemical and mechanical digestive systems.
Explanation:
Chemical and mechanical digestions are the two systems that are involved in the digestion of food. Some parts of digestive system broken down food with mechanical force such as mouth whereas some food is broken down into smaller substances with the help of chemicals such as juices of pancreas, liver, and intestine. Both systems are very important for the complete digestion of food particles into simpler substances in order to absorb by the cells to produce ATP.

Which organisms were the least numerous? Why? (In a forest environment!)
Answers
Because top consumers have less energy than producers, there is only enough food for a few top level consumers, but there is plenty of food for herbivores lower down the food chain.
What is forest ecosystem?Forest ecology is the scientific study of forest patterns, processes, flora, fauna, and ecosystems. Forest management includes forestry, silviculture, and forest management.
The existence of all species in the forest in a well-balanced and environmentally friendly manner is the function of the forest ecosystem.
Forest ecosystems are classified as boreal, temperate, or tropical rainforest ecosystems.
The transfer of energy from one trophic level to the next, up the food chain, is shaped like a pyramid, with the base being wider and the top being narrower.
Because of this inefficiency, there is only enough food for a few top-tier consumers, but plenty for herbivores lower down the food chain.
Thus, top consumers were the least numerous.

1A) There are 2 ways:-
• Anaerobic Respiration.
The anaerobic respiration process takes place in the absence of oxygen.
• Aerobic Respiration.
In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.
2A) Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.

Answers
Answer:
By reversing the concentration gradients for sodium and potassium ions.
Explanation:
Axons are long thread like nerve cells which impulses are conducted from the cells of the body to the other cells. Actions potential moves along with axons by reversing the concentration gradients. Most of the neurons in human brains are interneurons. The axons are presents in these nerve cells which connect with axon hillocks.

Answers
Answers: examples of host defence mechanism include: Innate anatomical and physiological barriers, Innate cellular and chemical defenses.
Explanation:
The capability of the human body to resist almost all types of organisms or toxins that tend to damage the tissues and organs is known as IMMUNITY. This host defence mechanism can be classified into INNATE or adaptive immunity.
The immunity that results from general processes, rather than from processes directed at specific disease organisms is called the INNATE IMMUNITY. The anatomical and physiological barriers of the innate immunity provides the first line of defence against pathogens. Examples of these barriers of the innate immunity includes:
--> Destruction of swallowed organisms by the low stomach pH and digestive enzymes
--> The vigorous mucociliary clearance mechanisms of the respiratory airways and lungs.
--> Resistance of the skin to invasion by organisms
While examples of innate cellular and chemical defenses include:
--> Phagocytosis of bacteria and other invaders by white blood cells and cells of the tissue macrophage System
--> lysozymes, a mucolytic polysaccharide that attacks bacteria and cause them to dissolute.
--> basic polypeptides which react and inactivate certain types of gram- positive bacteria
-->natural killer lymphocytes that can recognize and destroy foreign and tumor cells.
students are modeling mRNA during the process of protein synthesis. which answer choice correctly describes the model of mRNA strand being transcribed
Answers
Answer:
This question lacks options, the options are:
A. the mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine
B. the mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine
C. the mRNA strand is an exact copy of the DNA template strand; however uracil instead of adenine is paired with thymine
D. the mRNA strand is an exact copy of the DNA template strand; however, uracil instead of thymine is paired with adenine
The answer is B
Explanation:
Protein synthesis which encompasses how gene is used to synthesize proteins consists of two processes namely; transcription and translation.
- Transcription is the process whereby the sequence of a DNA template is used to synthesize a mRNA strand. The mRNA sequence is synthesized using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine base (A) will always hydrogen pair with Thymine (T) while Guanine (G) will always pair with Cytosine (C).
This means that the mRNA strand produced is complementary to the DNA template strand that was transcribed. However, Uracil base (U) replaces thymine (T) in the mRNA molecule because Thymine is not found in RNA. Hence, Uracil instead of Thymine pairs with Adenine in the mRNA.
That is;
A - U, T - A, G - C.
