____________ a regulatory protein that may bind DNA to inhibit transcription. ____________ a DNA sequence that binds a regulatory protein. ____________a DNA sequence that binds RNA polymerase and regulates transcription. ____________a compound that interacts with another protein or compound to form an active repressor ____________a compound that induces or activates transcription, such as lactose.a. Repressorb. Operator c. Promoterd. Corepressore. Inducer
Answer:
A repressor is a regulatory protein that may bind DNA to inhibit transcription. An operator is a DNA sequence that binds a regulatory protein. A promoter is a DNA sequence that binds RNA polymerase and regulates transcription. A corepressor is a compound that interacts with another protein or compound to form an active repressor. An inducer is a compound that induces or activates transcription, such as lactose.
Explanation:
Repressor proteins bind to DNA and RNA to suppress target gene expression. A DNA repressor blocks transcription by inhibiting the attachment of RNA polymerase to the promoter sequence, while an RNA repressor bind to the mRNA to block translation of the protein. An operator is a DNA sequence required for the attachment of transcription factors. The genes that are transcribed by the binding of a transcription factor to an operator sequence are collectively referred to as an operon. Operons are generally found in prokaryotes but they also can be found in some eukaryotes including Caenorhabditis elegans and Drosophila melanogaster. An inducer is a molecule that activates gene transcription either by binding to repressors/corepressors (thereby inactivating their functions) or by binding activators. For example, the allolactose act as an inducer of the lac operon.

How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA
Answer:
Total ATP molecules produced = 94 molecules of ATP
Explanation:
Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.
Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.
The overall yield of ATP from the various enzymatic steps is shown below:
Acyl-CoA dehydrodenase = 6 FADH₂
β-Hydroxyacyl-CoA dehydrogenase = 6 NADH
Isocitrate dehydrogenase = 7 NADH
α-Ketoglutarate dehydrogenase = 7 NADH
Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)
Succinate dehydrogenase = 7 FADH₂
Malate dehydrogenase = 7 NADH
Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,
Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5
Total NADH molecules = 27 * 2.5 = 67.5
Total ATP molecules produced = 19.5 + 67.5 + 7 = 94
Total ATP molecules produced = 94 molecules of ATP
Transposons need to __________________ in order to limit their negative impact on the genome of the host cell. A. control their nucleotide length B. regulate their copy number C. control their target-site choice D. avoid transposing into their own genome
Answer:
The correct answer is B
Explanation:
Transposons need to regulate their copy number to avoid errors with chromosomal pairing during meiosis and mitosis such as unequal crossover.
A typical example of this error is called the Alu Sequence or Elements. Alu elements contain more than one million copies found everywhere in the genome of human beings.
Many inherited human diseases such as cancer are related to Alu insertions.

b. found in the cytoplasm of eukaryotic cells.
c. a system of tracks used for transport.
d. composed of microtubules and microfilaments.
e. All answers are correct.
Answer: e
Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.
1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.
2. The cytoskeleton provides support and shape to cell.
3. It help in transporting substances through cell.
4. It help in phagocytosis.
5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.
6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
All answers are correct. Therefore, option (E) is correct.
What is cytoskeleton?The cytoskeleton is a complex network of protein filaments that extends throughout the cytoplasm of eukaryotic cells. It plays a number of important roles in the cell, including providing structural support, helping cells maintain their shape, and assisting in the movement of organelles and other cellular components. The cytoskeleton is also involved in the process of cell division, or mitosis, which is the process by which a single cell divides into two daughter cells.
The cytoskeleton is composed of three types of protein filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, thin protein fibers that form a kind of scaffolding within the cell. Microfilaments, which are made of actin proteins, are thinner than microtubules and are involved in muscle contraction and cell movement. Intermediate filaments are thicker than microfilaments and provide structural support to the cell. Together, these three types of protein filaments form a system of tracks that can be used for transport within the cell.

I want to know full answer about ecoregion vs. ecosystem.
Answer:
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point).

A map of North America's bioregions
Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Secondly, ecoregion boundaries rarely form abrupt edges; rather, ecotones and mosaic habitats bound them. Thirdly, most ecoregions contain habitats that differ from their assigned biome. Biogeographic provinces may originate due to various barriers, including physical (plate tectonics, topographic highs), climatic (latitudinal variation, seasonal range) and ocean chemical related (salinity, oxygen levels).

In humans, a type of blindness is due to a dominant allele (B). Normal vision is the result of a
recessive allele (b). Migraine headaches are due to a dominant allele (M), and normal (no migraines)
is recessive (m).
A male who is heterozygous for blindness and does not suffer from migraines marries a woman who
has normal vision and does not suffer from migraines.
Could they produce a child with normal vision who does not suffer from headaches? If yes, can the
probability of such a child be determined?
You must draw a Punnett square within the space provided to receive any credit for your answer!
Answer:
Yes, a child with normal vision who does not suffer from headaches can be produced.
The probability of producing such child from this cross is 1/2 or 50%
Explanation:
This question involves two distinct genes in humans. One coding for blindness and the other for Migraine headaches. The alleles for blindness (B) and Migraine (M) are dominant over the alleles for normal vision (b) and no Migraine (m).
According to the question, a male who is heterozygous for blindness and does not suffer from migraines will have the genotype; Bbmm while a female who
has normal vision and does not suffer from migraines will have genotype; bbmm. If these two parents are crossed, the following genotypes of gametes will be produced by each parent:
Bbmm- Bm, Bm, bm and bm
bbmm- bm, bm, bm, and bm
Using these gametes to construct a punnet square (see attached image), the following offsprings with genotypes; Bbmm and bbmm in the ratio 1:1 will be produced.
Bbmm (8/16) are offsprings with blindness and have no Migraine headache
bbmm (8/16) are offsprings with normal vision and have no migraine headache
Hence, this cross can produce a child with normal vision who does not suffer from headaches (bbmm). Also, the probability of producing such child is 8/16 or 1/2.

g. increases peripheral resistance : 1. Angiotensin II.
h. stimulated by baroreceptors in blood vessels: 2. Sympathetic Nervous System
i. stimulated by low blood pressure or volume: 3. Both
Explanation:
The antidiuretic hormone is one of the hormones released by the hypothalamus (regulator center in the brain) and collected by the posterior hypophysis from where they are then released again to the system. This hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood pressure. The osmotic receptors are located in the hypothalamus, while the pressure receptors are located in the heart, the aorta, and carotids. The amount of hormone secreted depends on these two aspects. Its function is to keep homeostasis and make kidneys conserve or excrete water to regulate its volume. The antidiuretic hormone stimulates water reabsorption when factors such as dehydration or hemorrhages are causing an increase in blood solutes. It might also stimulate water excretion when solutes in the blood are very low or blood pressure is too high.
Aldosterone is another hormone that acts stimulating the sodium ions reabsorption. This hormone production is controlled by a circuit named the renin-angiotensin-aldosterone system. This system is activated by the decrease of blood supply to the kidney, and hence, the decrease in blood pressure and sodium concentration. These factors cause the release of the renin, a proteolytic enzyme that acts on angiotensinogen producing angiotensin I which is converted into angiotensin II. Angiotensin II is a peripheric vasoconstrictor peptide, that can increase the blood pressure when it is circulating in the plasma. It also stimulates the secretion of aldosterone.
