One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.

Answers

Answer 1

Answer:

See the answer below

Explanation:

The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.

Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r.  The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:

                RR    x    rr

 F1         Rr    Rr    Rr    Rr  

phenotype ratio = all violet flower color

                 Rr    x    Rr

F2          RR    Rr    Rr    rr

phenotype ratio = 3/4 violet flower color and 1/4 red flower color

97 red flower offspring out of 400 is approximately 1/4.

Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

A well-known cell-survival pathway involves a kinase called _______ that is activated by the _______, leading to a larger chance that the cell will survive a stimulus that would normally lead to its destruction

Answers

Answer:

Protein kinase B (PKB); 3,4,5-triphosphorylated phosphoinositide (PIP3)  

Explanation:

Protein kinase B (PKB) is a kinase protein involved in receptor tyrosine kinase regulatory pathways. This enzyme attaches ATP-phosphate groups to serine/threonine residues in order to alter the activity of target protein substrates. PKB is involved in many cellular processes including transcription, cell proliferation and apoptosis. PKB is activated by the 3,4,5-triphosphorylated phosphoinositide (PIP3) enzyme and then this kinase propagates the signal to Akt (another serine/threonine kinase) by phosphorylation of its catalytic domain. The Akt/PKB signaling pathway is well-known to promote cell survival in response to extracellular signals/stimuli.

what are the causes of antibiotics resistance ?

Answers

Answer:

Over-prescription of antibiotics.

Patients not finishing the entire antibiotic course.

Overuse of antibiotics in livestock and fish farming.

Poor infection control in health care settings.

Poor hygiene and sanitation.

Explanation:

google

Answer: Antibiotic resistance has become a global threat, and with Antibiotic Awareness Week, it is important to understand the series of events that have led the world to this predicament. Originally touted as a miracle discovery, we are seeing that there can be too much of a good thing.

Explanation: The use of antibiotics has saved millions of lives, but its pervasive use to treat any infection, whether serious, minor, or even viral has lead to the increase in antibiotic resistance.  Antibiotics strictly target bacteria, but it is sometimes difficult to differentiate between viral and bacterial infections without costly tests. It is often less time-consuming and more cost effective to proactively prescribe antibiotics, rather than take precautions and prescribe only the correct treatment.

Another issue with antibiotics is the inability to monitor patient intake.  Antibiotic dosages are designed to eradicate entire populations of the pathogens. When antibiotics are not taken for the entire prescribed course, pathogenic bacteria can adapt to the presence of low dose antibiotics, and eventually form a population that is completely resistant to the antibiotic regardless of the dosage.

Antibiotic usage is also not exclusive to humans. Every day, antibiotics are used to treat livestock and fish to prevent infections.  Similar to overuse in humans, uncontrolled use of antibiotics creates a reservoir of bacteria that could become resistant, thus rendering the antibiotic useless.

During the bacterial transformation lab, what was the primary purpose of including Ampicillin in the agar

Answers

Answer:

allows for selection of E. coli mutants that successfully picked up the plasmid

Explanation:

Ampicillin is a penicilin type medicine or antibiotic that can treat the infections caused by bacteria.

In bacterial transformation lab, the ampicillin is added in the agar in order to select the E.coli mutants which picked the plasmid and have gained ampicillin resistance gene. Bu doing so, it causes the production of the enzymes that prevents the activity of the ampicillin as well as the bacteria survive. The ampicillin antibiotics present in the agar kills the bacteria without having the ampicillin resistance gene.

When eating food, what anatomical and functional divisions of the nervous system are involved in the perceptual experience?

Answers

Answer:

Taste afferents reach the geniculate, inferior petrosal, and plexiform ganglia and then proceed to the brain stem to synapse in the solitary tract of the medulla oblongata. Nerve branches branch from here to the lateral hypothalamus, the amygdala, and the thalamus

Explanation:

The taste sensitivity of the tongue is conveyed by three different cranial nerves (VII, IX and X). The taste buds of the anterior two thirds of the tongue are innervated by the chorda tympani nerve, a branch of the facial. The facial nerve also collects the taste sensitivity of the soft palate through another of its branches, the greater superficial petrosal nerve.At the thalamic level, cross relationships are established with the contralateral gustatory nucleus and convergence with other lingual and olfactory afferences of the piriformis cortex. Third-order neurons are sent from the thalamus to the parietal cortex. Somatosthetic fibers have mainly contralateral projections, while taste projections are ipsilateral.

The sensation associated with taste when eating food is primarily sensed by nerves that are located in the peripheral nervous system (PNS) and they are involved in sensory and somatic functions.

A nervous system refers to a neural network that comprises nerve cells and fibers, which are used for the transmission of neural impulses (signals) around the various body parts of a living organism.

In living organisms, the nervous system is made up of two (2) major components and these are;

Central nervous system (CNS)Peripheral nervous system (PNS)

Generally, the peripheral nervous system (PNS) is the anatomical and functional divisions of the nervous system that is responsible for perceptual experience when eating food. Thus, the sensation associated with taste when eating food is primarily sensed by nerves that are located in the peripheral nervous system (PNS).

The PNS nerves that are involved in sensory and somatic functions include:

Cranial nervesPeripheral nervesSpinal nerves

How does petrification link to how the oldest fossils are found in the lowest rock

Answers

Answer:

Explanation:

In geology, petrifaction or petrification is the original material and the filling of the original pore spaces with minerals. Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified. Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone. This generally occurs by filling the pores of the tissue, and inter and intra cellular spaces with minerals, then dissolving the organic matter and replacing it with minerals. Researchers at UCLA and the University of Wisconsin–Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.

Why are seals able to live the coast of Antarctica while frogs snakes, and panthers not?


A. Seals can swim

B.seals are predators

C.seals have fur and blubber

D.seals are warm-blooded animals

Answers

Tbh it’s either c or d because c and d are both correct
The answer is C. My answer is because A and B are irrelevant to the question, so for that it can be eliminated. But between C and D, C makes much sense. Although D, says that seals are warm blooded and is true, however frogs (amphibians) and snakes (reptiles) they are cold blooded. They need sun in order to feel warm or the heat to adjust or accommodate their bodies temperatures, unlike panthers and seals they’re warm blooded they naturally have fur and are able to regulate their bodies temperature. Therefore D is eliminated. The correct answer is C, because seals have fur and blubber it’s much more durable, and are almost as if impenetrable for the freezing water and colder weather to pass through their fur. That is why they are able to live the coast of Antarctica.

C.

Answers

The correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new source of energy.

Explanation

As is mentioned in the statement, the energy from a hydroelectric plant is obtained through the movement of water that makes move some blades which produce energy with it. lLater, this is transformed and transported to the cities. However, to obtain these clean natural renewable resources, it is necessary to take into account what environmental factors may be affected with the implementation of a hydroelectric plant, because the operation of hydroelectric can affect natural processes such as fish migration, patterns of reproduction, feeding, among others that take place in a river, having negative consequences for these species which would cause an imbalance in nature. According to the above, the correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new energy source.
