Describe the relationships among amino acids, chromosomes, proteins, and genes in the cells of a jackalberry plant. Make sure to include how gene expression is related to protein synthesis.
Answer:
The jackalberry plant is a multicellular organism whose cells contain chromosomes. The chromosomes contain genes that are transcribed to produce messenger RNAs, which are then translated into proteins
Explanation:
The Jackalberry tree is a plant, i.e., a multicellular organism. Multicellular organisms have chromosomes in the nucleus of each cell. A chromosome is a long DNA molecule that contains part (or even all) of the genetic information of a particular organism. Genes are specific segments of the chromosomes, which are expressed in a process called 'transcription' where a gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, these mRNAs are used to synthesize proteins by a process called 'translation'. In an mRNA molecule, each specific triplet of nucleotides is known as a codon and corresponds with a specific amino acid during protein synthesis. Thus, the mRNA sequence dictates the correct order of amino acids (i.e., the building blocks of proteins) in the polypeptide chain.
what is the importance of ATP and NADPH?
Answer:
The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
These electrons are used to produce NADPH as well as ATP in a series of reactions called the light reactions because they require light. NADPH and ATP formed by the action of light then reduce carbon dioxide and convert it into 3-phosphoglycerate by a series of reactions called the Calvin cycle or the dark reactions.

Suresh and Gail are students in a lab working on mice with defects in the function of the HOX3A gene. In the special mouse line they are working on, no sequence changes are present in the genomic DNA of HOX3A, but the gene is not expressed properly and a mutant phenotype results. In one mouse line, an mRNA is produced in normal amounts, but no HOX3A protein can be detected.
Suresh thinks the absence of protein results from a change in RNA processing that prevents the inclusion of an exon in the final mRNA. Gail thinks the absence of protein results from some second gene that produces a protein that binds to the 3'UTR. Which of the two could be correct?
A) Only Suresh could be correct.
B) Only Gail could be correct.
C) Both Suresh and Gail could be correct.
Answer:
C) Both Suresh and Gail could be correct.
Explanation:
The pre-messenger RNA (pre-mRNA) transcript obtained after transcription of eukaryotic genes must undergo several processing events, including a process known as intron splicing, where introns (i.e., the non-coding sections of an RNA transcript) are removed and exons (coding regions) are joined to form a mature mRNA molecule. The three prime untranslated (3′-UTR) region of this mRNA can also bind to regulatory non-coding RNAs such as, for example, miRNAs which inhibit gene expression by inhibiting translation and/or by triggering its degradation. Moreover, the 3′-UTR region may also contain silencer sequences that bind to repressors in order to inhibit gene expression. On the other hand, translation refers to the process by which an ordered polypeptide chain (i.e., a protein) is synthesized by using the information contained in an mRNA molecule. In consequence, in the case under consideration, the mutation in the second gene could affect both RNA processing and the regulation of translation, thereby equally affecting HOX3A protein synthesis.

Answer:
In areas of Africa where malaria is prevalent the number of sickle cell cases remains consistent generation after generation. ---- support the hypothesis.
In Canada the incident of sickle cell anemia has been increasing in the population. ----- contradicts the hypothesis.
Explanation:
In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.

what are the names of the three domains
A.bacteria,archaea,eukaryotic
B.bacteria,archaea,animalia
C.archaea,plantista,animalia
D. Life,animals,plants
Answer:
A. bacteria, archaea, and eukaryotic.
Explanation:
Bacteria, archaea, and eukaryotic are the three domains of life.
The three domains system was globally implied. The three domains were Archae, Bacteria and Eukarya. The correct answer is option A.
The three domains of Carl Woese's categorization system are archaea, bacteria, and eukaryotes. The six kingdoms are archaebacteria (ancient bacteria), eubacteria (actual bacteria), protozoa, fungi, plants, and animals.
This classification system divides life into several groups based on differences in the 16S ribosomal RNA (rRNA) structure, the lipid composition of the cell membrane, and antibiotic sensitivity. The main distinction from earlier classification schemes is the division of Kingdom Monera into Archaea and Bacteria.
Therefore, the names of three domains given by Carl Woese were Archae, Bacteria and Eukarya i.e. option A.

How is gravitational lensing related to dark matter?
A.Dark matter emits lens-shaped rings of light.
B.The gravity of dark matter distorts light from distant sources.
C.The gravity of dark matter absorbs light from distant sources.
D.Dark matter uses gravitational lensing to create dark energy.
Answer: B) The gravity of dark matters distorts light from distant sources.
Explanation: In spite of the fact that stargazers can't see the dull matter, they can recognize its impact by seeing how the gravity of enormous world bunches, which contain dim matter, twists, and misshapes the light of more-far off systems situated behind the group. This marvel is called gravitational lensing.
The gravity of dark matter distorts light from distant sources.
What is gravitational lensing?Hubble's is perfectly adapted for examining the fascinating visual phenomena that gravity may produce when taken to its limit. The general theory of relativity developed by Albert Einstein describes how mass concentrations warp the universe around them.
When a massive mass of matter, such as a group of galaxies, produces a gravitational field that bends and magnifies light from distant galaxies that are in front of it but in the same line of sight, the result can be a gravitational lens.
Therefore, The gravity of dark matter distorts light from distant sources.

What happens when gases, like carbon dioxide, get trapped in the atmosphere?
Answer: Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse.
Explanation: These heat-trapping gases are called greenhouse gases. During the day, the sun shines through the atmosphere.
Gases like carbon dioxide is a green house gas. It can trap the temperature radiated from the earth surface and return back the heat in the surface. Therefore, if the carbon dioxide gas is trapped in the atmosphere, the atmospheric temperature increases.
What is green house effect ?The heat energy from sun is radiated to the earth surface make the planet warmer. However, some fractions of the heat is radiating back from the atmosphere.
Gases like carbon dioxide, methane etc. are capable of absorbing the temperature intensely and make the atmosphere warmer. These gases are called green house gases and the effect is known as green house effect.
Green house effect leads to rise in global warming. Hence, if the gases like carbon dioxide is trapped in the atmosphere, the temperature increases.

Answer:
The correct answer is edema.
Explanation:
When the capillaries or the tiny blood vessels within the body leak fluid, the condition known as edema takes place. This fluid accumulates in the tissues surrounding it, resulting in inflammation. Edema generally takes place due to mild conditions like consuming more salt, staying or sitting in one position for a long duration, and others.
However, in some situations, edema can also be a sign of an extreme medical condition like kidney disease. During kidney disease, the sodium and additional fluid within the circulation may result in edema. The edema related to kidney disease generally takes place around the eyes and in the legs.
