The DNA sugar phosphate structure carries an overall negative charge due to the pKa of one of the phosphate groups being much less than physiological pH, and another very close to physiological pH. What overall charge do histones carry on their surface?A. negativeB. positiveC. No answer text provided.
Answer:
B. positive
Explanation:
Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.

Basic fibroblast growth factor binds to glycosaminoglycans in the extracellular matrix. Which amino acids would you expect to be abundant in the protein? A. Glu B. Asp C. His D. Gln E. Arg F. Lys G. Asn
Answer:vggvchbhk
Explanation:
Given the roles of NAD /NADHNAD /NADH in dehydrogenation reactions and NADPH/NADP NADPH/NADP in reductions, would you expect the intracellular ratio of NAD /NADHNAD /NADH to be high or low? what about the ratio of NADP + to NADPH? Explain.
Answer:
The correct answer would be - high intercellular ratio the ratio of NAD/NADH and low intercellular ratio the ratio of [NADP+]/[NADPH]
Explanation:
The role of NAD/NADH in dehydrogenation reactions and NADPH/NADP in reductions explains that to promote or increase the oxidation of substrates the ration of NAD+/NADH should be high:
malate + NAD+ <===-> OAA +NADH + H+.
As NADPH and NADP+ generally help to increase the reduction of substrates, so we expect the ratio of [NADP+]/[NADPH] to low.
What type of protein in cAMP signal transduction would be analogous to the phosphatase of the phosphorylation cascade
Answer:
Phosphodiesterase
Explanation:
Phosphodiesterases are enzymes capable of breaking down phosphodiester bonds. There exist 11 different types (families) of phosphodiesterases that have distinct 3D structures and kinetic properties. Moreover, the cyclic nucleotide phosphodiesterases are a group of enzymes that hydrolyze the phosphodiester bond in nucleotide second messenger molecules such as, for example, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). Thus, cyclic nucleotide phosphodiesterases represent a family of enzymes that modulate the localization and duration of nucleotide second messenger signaling.

Subunits of skeletal muscle fibers that are composed of sarcomeres are called ________. Subunits of skeletal muscle fibers that are composed of sarcomeres are called ________. myofibrils transverse tubules sarcolemmas myofilaments
Answer:
The correct answer is myofibrils
Explanation:
The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.
The proximal tibiofibular joint can be compared to the proximal radioulnar joint. In what ways are these two joints similar, in what ways do they differ?
Answer: A joint is a site of fusion of two or more bones.
Explanation:
The proximal tibiofibular joint is a joint that is formed by the articulation of the tibia and fibula bones, whereas the proximal radioulner joint is the joint that is formed by the articulation of the radius and ulna bone.
The proximal tibiofIbular joint allows very little movement to the bones whereas proximal radioulner joint allows supination and pronation of the forearm bones.
The similarity is that these joints are present in between the long bones.
These joints are connected with that of the bones via fibrous interosseous membrane.

If a trait has no genetic variance in a population but still has phenotypic variance, its narrow-sense and broad- sense heritability are both equal to zero. True False
Answer:
The given statement is false.
Explanation:
Irrespective of being broad sensed or narrow sensed, heritability demonstrates a prediction of variation in the phenotypic trait in the organism's population, which has originated due to genetic variation between the individuals within the population. Apart from determining phenotypic variation because of genetic variation, it also determines the origination of the phenotypic variations because of the elements other than random chance or environment. Heritability holds for the origination of the changes taking place due to non-genetic factors as well.
When one talks about the changes taking place due to additive factors or the factors other than genetic factors it comes under narrow-sense heritability, while the broad sense heritability majorly deals with genetic factors. Thus, based on the given statement, the narrow-sense heritability cannot be considered as zero for the phenotypic variations originating because of other genetic variations.
The genetical variance refers to the concept of natural selection. It states a change in biological fitness is calculated by the variance from the fitness itself.
The phenotype variance usually combines the genotype variance. It has three major parts such as additive, dominance, and epistatic variance. Thus the statement it's a narrow sense and broad heritability are false.Learn more about the variance in a population but still has.

haploid, gametes, gene, pair of homologous chromosomes, meiosis, egg, sperm, fertilizes or fertilization, zygote, diploid
Answer:
The definition including its issue is listed mostly in the clarification subsection below.
Explanation:
Respectively parents cells were indeed diploid as well as comprise possible combinations of chromosomes (homologous). These chromosomes seem to be essentially 2 segments of DNA that encompass a certain genetic sequence, within every parent plant.
Meiosis is formed in these cells, resulting in the development of gamete (haploid). Two very different gametes are undergoing a mutation termed fertilization. Everything leads to the creation of a zygote.Zygote increasingly distinguishes which removes itself from the genetically modified organism.In Punnett square, the female parent's genes are written

what causes surface runoff?
a) evaporated water vapor runs down mountains
b) plants absorb water and then release it to run down hills
c) soil infiltration reached capacity
d) oceans overflow
Answer:
C
Explanation:
Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. ... Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.
The surface runoff is caused by the soil infiltration reaching capacity, which is present in Option C, and the surface runoff means when the water can't be absorbed into the soil and excess water flows away.
What are the harmful effects of the runoff water?Runoff water occurs when water cannot be absorbed into the soil and overflows, causing numerous negative effects on both animals and plants. When water is absorbed by the soil, the groundwater level increases, which can later be used by humans for different purposes. When the water overflows and can't be stored, that causes many harmful effects, such as the flood situation. Climate change and global warming further add to the surface runoff water, and it causes severe harm to the urban areas as there are fewer plants, so the water harms the animals and humans.
Hence, the surface runoff is caused by the soil infiltration reaching capacity, which is present in Option C.

Are you concerned about the threat of zoonotic diseases? Why or why not?
Answer: There should be concern because zoonotic diseases passes from an animal or insect to a human very easily, and although they do not always represent a danger, they can cause serious symptoms and even death.
Explanation:
Zoonotic diseases are caused by microorganisms such as bacteria, virus, parasites and fungi, and they can be transmitted between animals and humans. Some examples of zoonotic diseases are Brucellosis, Anthrax and Rocky Mountain Fever (rickettsiosis)
Sometimes, people with zoonotic infections can get very sick and have symptoms such as fever, diarrhea, muscle pain and others. While in other cases, people may have no symptoms and never get sick, without representing a risk . Besides being important because they can make many people sick, we have to take into account that the way of transmission or propagation can be very simple. Food can be a source of zoonotic infections, for example when farm animals re infected with parasites and these animals are consumed as food. Another example is when people get trichinosis by eating undercooked meat, or consuming fruit without washing it properly, or raw meat from animals infected with the Trichinella parasite. Also, people can get the parasites swimming in a lake if they accidentally swallow water contaminated with the feces of infected animals. Besides, pets can have parasites and pass them on to people, and wild animals can also have infection from parasites that can infect people.
Therefore, we must be concerned about zoonotic diseases, since they can be transmitted very easily from animals to humans, and although they do not always represent a danger, they can cause serious symptoms and even death.
