The botanist wanted to produce a generation of snapdragons that all had pink flowers.

State the phenotypes of the parent plants that the botanist would need to cross.
Explain your answer.​

Answers

Answer 1

Answer:

He would need to cross one homzygous red (RR) and homzygous white (rr)

Explanation:

Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.

According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.

What do you mean by Natural selection?

Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.

The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.

Answer:

c

Explanation:

It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

What was  Hershey-Chase experiment?

The Hershey-Chase experiment, also known as the "Blender Experiment," was a classic experiment in molecular biology that was conducted in 1952 by Alfred Hershey and Martha Chase. It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

In the experiment, components of the bacteriophage were labeled with radioactive isotopes of sulfur and phosphorus. The labeled phages were then used to infect bacterial cells, and the cells were subjected to various treatments to separate the viral components from the bacterial components.

The results of the experiment showed that the genetic material of the bacteriophage was made of DNA, not protein. This was determined by the fact that the labeled DNA, but not the labeled protein, was able to enter the bacterial cells and infect them. This experiment provided strong evidence for the "central dogma" of molecular biology, which states that genetic information flows from DNA to protein, but not the other way around.

1. A cinder cone is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or cinder that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.

FORMS : Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.

2. Lava flows are streams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains.

FORMS : Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot.

3. A shield volcano is a type of volcano usually composed almost entirely of fluid lava flows. It is named for its low profile, resembling a warrior's shield lying on the ground.

Lavas, particularly basaltic ones, come in two primary types: pahoehoe (pronounced 'paw-hoey-hoey") and aa (pronounced "ah-ah"). Both names, like a number of volcanological terms, are of Hawaiian origin. A third type, pillow lava, forms during submarine eruptions.
Answer
Volcano A - Cinder Cone Volcano
Volcano B - Composite Volcano
Volcano C - Shield Volcano

4. Cinder cones are known for their very violent, explosive, exciting eruptions. (A)

Composite volcanoes are explosive, towering giants. (B)

Shield volcanoes quietly produce broad, massive structures through lava flows. (C)

5. Composite volcanoes have very sticky and thick lava, which can make them very explosive when they erupt: gas bubbles that are trapped in the magma chamber find it hard to escape through the viscous rock. They can also spurt lots of hot ash and rocks into the air, making them extremely dangerous.

Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year.

The model of the carbon cycle determines the amount of earth's carbon is constant. Thus, option A is correct.

Carbon is the element that is responsible for the major life forms on earth. The conversion of carbon in varying life forms and the reservoir is given by the carbon cycle.

What is the effect of the carbon cycle on the amount of carbon?

The carbon cycle is operated for the analysis of the conversion of the carbon in different states and life forms in the earth.

The conversion results in the change in the state of the carbon and its concentration in different constituents.

Yes.

Yes, amino acid can not be factor or broken down because it is the smallest unit of proteins. Proteins are made up of about 20 small amino acids. Proteins can be factor into amino acids but amino acids can't be factor into proteins because proteins are made up of amino acids but the amino acids does not formed from proteins so that's why Tim does not factor his amino acid  into total protein.

2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?

Answers

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

GranulationRecrystallizationMetasomatismMassiveFoliation

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.

If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

What is a foliation?

Foliation on a rock means continuous multi layering on a metamorphic rock.

These layers can be thin as a sheet of paper.

Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.

Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

Fungus is a eukaryotic organism. They grew in soils and wood and moist and dark places. Fungi break down the material. While consuming the nutrients in the decaying matter, they produce enzymes that break down the material.

The biomass would be overrun with the dead matter without the majority of fungi, which is why they are helpful. Bacteria and actinomycetes are some additional decomposers. They act as nature's recycling machine by consuming animal carcasses, bones, dead plants, and various minerals thanks to their enzymes.

In order to survive, bacteria can create mechanisms known as resistance against antibiotics and antifungals. The germ's resistance mechanisms are determined by the specific proteins that DNA instructs the germ to produce. Many different forms of resistance genes can be found in bacteria and fungi.

Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.

What oftenest offends me at the houses of married persons where I visit, is an error of quite a different description;it is that they are too loving.Not too loving neither: that does not explain my meaning. Besides, why should that offend me? The very act of separating themselves from the rest of the world, to have the fuller enjoyment of each others society, implies that they prefer one another to all the world.But what I complain of is, that they carry this preference so undisguisedly, they perk it up in the faces of us single people so shamelessly, you cannot be in their company a moment without being made to feel, by some indirect hint or open avowal, that you are not the object of this preference. Now there are some things which give no offence, while implied or taken for granted merely; but expressed, there is much offence in them. If a man were to accost the first homely-featured or plain-dressed young woman of his acquaintance, and tell her bluntly, that she was not handsome or rich enough for him, and he could not marry her, he would deserve to be kicked for his ill manners; yet no less is implied in the fact, that having access and opportunity of putting the question to her, he has never yet thought fit to do it. The young woman understands this as clearly as if it were put into words; but no reasonable young woman would think of making this the ground of a quarrel. Just as little right have a married couple to tell me by speeches, and looks that are scarce less plain than speeches, that I am not the happy man,the ladys choice. It is enough that I know I am not: I do not want this perpetual reminding.The display of superior knowledge or riches may be made sufficiently mortifying; but these admit of a palliative. The knowledge which is brought out to insult me, may accidentally improve me; and in the rich mans houses and pictures,his parks and gardens, I have a temporary usufruct at least. But the display of married happiness has none of these palliatives: it is throughout pure, unrecompensed, unqualified insult.Marriage by its best title is a monopoly, and not of the least invidious sort. It is the cunning of most possessors of any exclusive privilege to keep their advantage as much out of sight as possible, that their less favoured neighbours, seeing little of the benefit, may the less be disposed to question the right. But these married monopolists thrust the most obnoxious part of their patent into ourfaces.Nothing is to me more distasteful than that entire complacency and satisfaction which beam in the countenances of a new-married couple, in that of the lady particularly: it tells you, that her lot is disposed of in this world: that you can have no hopes of her. It is true, I have none; nor wishes either, perhaps: but this is one of those truths which ought, as I said before, to be taken for granted, not expressed. The excessive airs which those people give themselves, founded on the ignorance of us unmarried people, would be more offensive if they were less irrational. We will allow them to understand the mysteries belonging to their own craft better than we who have not had the happiness to be made free of the company: but their arrogance is not content within these limits. If a single person presume to offer his opinion in their presence, though upon the most indifferent subject, he is immediately silenced as an incompetent person. Nay, a young married lady of my acquaintance, who, the best of the jest was, had not changed her condition above a fortnight before, in a question on which I had the misfortune to differ from her, respecting the properest mode of breeding oysters for the London market, had the assurance to ask with a sneer, how such an old Bachelor as I could pretend to know any thing about such matters.All the following are mocked in the passage EXCEPTA.intelligence gained as a result of marriageB.undisguised preference of married couples for their spouseC.condescension of married females to bachelorsD.married individuals presumptive knowledgeE.overt cruelty of married couples to unattractive unmarried femalesPlease select the best answer from the choices providedABCDE What cell part supports the structure of the system plant cell Anyone please i need a free write it doesn't have to be long just a paragraph 8th grade performance level
