First off it would 'attack' the immune system, the virus would attach itself to healthy cells, then continue to move through your body - your bodies first response is always going to be your immune system - it's going to fight the foreign visitor aka the virus. The virus will then move down towards your respiratory system. And given the symptoms that you may experience whilst your body is fighting the virus is how it may work with other systems (these two being the main ones) for example; diarrhea, nausea/vomiting, headaches, sore throat, etc. And it will also depend on the patients history.

B) Euchromatin can be highly expressed
с
none of the answers are false
D
A nucleosome consists of DNA wound around a core of 8 histone
molecules.
E Highly compacted chromatin is generally not expressed at all.
Answers
Answer:
The correct answer is - A. Tight DNA packing tends to promote gene expression.
Explanation:
Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.
DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .
DNA packing decreases its transcription and hence no expression.
Explain incomplete dominance, using snapdragon
flowers as an example.
Answers
Answer:
Dominant allele does not completely conceal recessive allele.
Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.
Explanation:
Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.
For example, in snapdragons:
The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.
However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.
Hope this helped!
Answer:
Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.

Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway. You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal. You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present. When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
Answer the following question in the space give.
A. From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.
Answers
Answer:
The answer is "PK1 activates PK2"
Explanation:
All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.

B group would represent the decomposer organisms. Therefore, the correct option is B.
What are Decomposers?Decomposers are organisms that convert decaying organic matter into more basic components. They are an important component of the nutrition cycle because they convert complex chemical substances, such as nitrogen and carbon, into direct nutrients that can be absorbed by plants and other living things.
Some species of bacteria, fungi and insects are specialized decomposers. These organisms are essential to maintaining healthy soil because they aid in the recycling of nutrients and the breakdown of organic matter, which would otherwise build up and cause nutrient imbalances. Decomposers, which break down dead organisms and aid in the containment of pathogens, may be important in disease prevention.
Therefore, the correct option is B.

Immunization with the childhood DPT (diphtheria, pertussis, and tetanus) vaccine protects against subsequent exposure to tetanus by Group of answer choices generating tetanus-specific memory B cells. producing life-spanning antitetanus IgE antibodies. stimulating quick inflammation upon future exposure. preloading antigen-presenting cells. stopping isotype switching of B cells from IgM to IgA.
Answers
Answer:
generating tetanus-specific memory B cells
Explanation:
Memory B cells are cells of the immune system that produce antibodies against specific antigens present in pathogenic organisms. The B lymphocyte cells produce clonal memory B cells after the first exposure to the antigen, a process known as clonal selection. Subsequently, memory B cells that circulate in the bloodstream trigger a rapid secondary immune response (after a second exposure to the antigen) by producing antibodies against specific antigens that activated their parent B cell. Moreover, the DPT vaccine includes purified tetanus toxins (i.e., target antigens) that induce clonal expansion in specific B cells, thereby generating a population of memory B cells that produce specific antibodies rapidly in secondary immune responses.

a. whale and human or whale and tuna
b. pig and rhesus monkey or pig and chicken
c. tuna and fly or tuna and chicken
Answers
Answer:
a. whale and tuna
b. pig and chicken
c. tuna and fly
Explanation:
Following, you will find characteristics of each species that differ in the contrasting groups. These descriptions reflect the divergence degree between groups.
a. whale and tuna
Whales: Vertebrate and Big-sized marine mammals. They are long-lived and pulmonate animals. They are relatively slow, and only breathe while they are on the surface, opening the blowhole which covers the narines. Despite being mammals, they lack hair, so they have naked soft skin. They have one dorsal fin, two lateral flippers, and a caudal horizontal fin, which they move up and down. They are viviparous, with internal fecundation, and females carry mammal glands to feed their offspring. They feed on krill and other small animals, which they filtrate using their baleens. Whales exhibit the Type I survivorship curve. Mortality often occurs at the end of the cycle. They have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. They are used to swim deep depth or near the surface depending on the reproductive cycle stage. Tuna: Bony marine fish. Fusiform and medium-sized body, fast swimmers. They can live for 15 years. Their body is covered with scams. They have two dorsal fins, two ventral fins, two lateral fins, and a caudal fin which they move from side to side. It swims near the surface and interchange gas using the grills. They have many teeth and feed on anything they can, such as small fishes, zooplankton, crustaceans, and mollusks. They have external fecundation and exhibit the Type III survivorship curve. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.b. pig and chicken
Pigs: Heary Mammal, with thick hairs, called bristles and mammal glands. They are four-legged, have hooves and four fingers. Their snout is long and flexible, with sharp teeth. They have a curly tail and thick and sensitive skin. Naturally, they are herbivorous but became omnivorous in captivity. They can live for ten or fifteen years. Viviparous. Well-developed smell sense and no sudoriparous glands. Territorial, dominant, and highly communicative with partners. They can use more than twenty different sounds. They also exhibit the Type I survivorship curve.Chickens: Birds. They have two legs and two wings however, it has never been successful in flying. Their body is cover by feathers. They have no hair, and they do not have teeth either, but they have a corneous peak instead. They are omnivorous. They show sexual dimorphism, especially in feathers and crests. They exhibit the type II survivorship curve. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.c. tuna and fly
Tuna: Already described aboveFly: Flying and small-sized Insects. Dipterous, with their bodies divided into three regions: Head, thorax, and abdomen. They have six appendixes to walk, one pair of wee-developed wings, one pair of vestigial wings, eyes very sensitive to light. The mouthparts are used to lick, suck or bite. Some species can sting and suck blood from humans. Their body is covered with thin hairs and sensory bristles used to taste, feel, and smell. They are attracted by smelly matter, from which they feed on. In general, flies are associated to matter in decomposition and wastes. They have a short life cycle and can live up to twenty-five days. Ovoviviparous species, laying too many eggs that will turn into larvae and finally to the adult fly stage.Based on Model 3, the pairing of organisms that would have the most divergence in their DNA is: A. whale and human or whale and tuna.
What is genetics?Genetics can be defined as the scientific study of genes, chromosomes, heredity and the similarities or divergence (variations) of traits (DNA) in living organisms such as animals, humans, and plants.
Based on morphology and ecology, whales are aquatic and gigantic vertebrate (mammals) that only live in water. Also, whales are pulmonate and carnivorous animals that feed on other animals.
From Model 3, the number of amino acids differences between whale and human is ten (10) while that of whale and tuna is equal to seventeen (17). Therefore, we can deduce that the pairing of organisms that would have the most divergence in their DNA is whale and human or whale and tuna.
