Hershey and Chase crossed bacteria that contained marked DNA and marked proteins. What did they observe in the offspring bacteria?

Answers

Answer 1

They observed in the offspring bacteria that there was the presence of marked DNA after crossing.

What is DNA?

This is referred to as deoxyribonucleic acid and contains the genetic instruction in organisms.

Hershey and Chase experiment involved using bacteriophages to infect a bacteria in which the DNA entered with little or no protein. The presence of marked DNA in the bacteria means it is the biomolecule involved in reproduction.

Friction can absolutely causes a moving object to stop (stationary). So, the answer is True.

What is Friction?

It is a type of force that tries to slow down or stop the movement of a moving object when the two surfaces are touching each other.

To stop the object, surfaces also play an important role. For example, Rough surfaces produce more friction otherwise things would be just rolling.

companies that conduct a great deal of research to learn how they can successfully put the marketing concept into practice most likely have a blank orientation.

Answers

Companies that conduct a great deal of research to learn how they can successfully put the marketing concept into practice most likely have a market orientation.

An approach to business known as a "market orientation" concentrates on using research and development to satisfy the requirements and wants of customers rather than on internal production capabilities or the launch of new products.

A business that is market-oriented prioritizes its customers, continuously assessing their needs and preferences in order to create new goods and services that more effectively address those needs.

A business that is focused on the market will use market research to better understand its consumers, rivals, and industry trends in order to customise its marketing initiatives to appeal to its target market.

snapping division, seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell.

Answers

While the two daughter cells were inherited from the same parent cell, binary fission is indeed an asexual mode of reproduction and the main means for reproduction in bacteria.

In mitosis, what's a parent cell?

The parent cell is indeed the unit that divides during cell division to produce two daughter cells. The two offspring cells produced during mitosis share the same genetic makeup as the mother cell. In mitosis, the daughter cells contain half as many chromosomes as the parent cell and a distinct genetic makeup.

Parent cells where are they?

In mitosis, a parent cell serves as the initiating cell for cell division. The reason why parent cells are thus termed is just because they give rise to new cells, which are the progeny cells.

However, pet owners have released large numbers of unwanted turtles into warm natural waters of the Gulf of Mexico.

Answers

Two possible consequences of the release of these turtles into Gulf waters, including the effect on native turtle species are

Competition with native turtle speciesAlteration of ecosystem dynamics

What are possible consequences of the release of these turtles into Gulf waters?

An invasive turtle species poses direct competition with native turtles within Gulf of Mexico, resulting in possible shrinkage in population sizes for the latter group. Resource scarcity driven primarily by competition over access to nests, habitats and food sources can render natives less effective at these activities compared to their new rivals.

Furthermore, identifying underlying consequences triggered by invasive species' potential alteration of ecosystem dynamics (eg: substantial loss or balanced gain) remains crucial for further consideration. The issue of climate change represents an imminent danger that threatens the well-being of our planet. Swift action from all corners of society is required, including private citizens, companies, and governing bodies across national borders.

Here law of independent dominance, works

Which of these Punnett squares shows a cross that predicts green peas (y) in half of the offspring?

Answers

In the following Punnett squares showing crosses that predict green peas (yy) in half of the offspring are (y, Yy) and (Yy, yy).

The Punnett squares is a diagram designed by Reginald Punnett, hence the name. It is widely used in biology to find out all the probabilities or combinations that can be generated in a gamete and to find out more information about the offspring.

In a Punnett square, all possible combinations will be observed between the dominant allele (which will be written in capital letters) and the recessive allele (which will be written in lowercase). In this way, the probable genotype but not the phenotype will be known. In other words, we can say that it is about knowing one of the basic principles of genetics. That is, examining the genes that are passed on and the chances that children have of getting them.

In terms of the prediction of green beans (yy), half of the offspring are (y, Yy) and (Yy, yy) which are combinations of dominant alleles and recessive alleles.

Answers

The prompt is culled from "HonerScience" Gizmo. The objective is the compare the Planetary motion of Pluto's Orbital Radius, against the period of it's Orbit as depicted in the Gizmo. It is to be noted that Pluto's Orbital Radius is 39.529 AU while it's period of Orbit is 249 years.

What is Orbital Radius?

For roughly circular orbits, the orbital radius is the distance between an item in space and the body it is circling. When an object circles a body in space, it spins around it, forming a circle or an ellipse depending on the orbit.

If the mass of the orbiting star is known, Kepler's Third Law may be used to calculate the planet's orbital radius (R3=T2Mstar/Msun, the radius is in AU, and the period is in earth years).

The earth's radius and the radius of its orbit around the sun are 6371 km and 149x109 km, respectively.

Why are these "rules of thumb" sometimes unreliable?​

Answers

Answer:

Rules of thumb are not scientific and do not take into account the individual circumstances and needs of a person, so they may not be applicable to your particular situation.

"Rules of thumb" are general guidelines or heuristics that people use to make quick decisions or judgments. While they can be helpful in many situations, they are sometimes unreliable for several reasons, such as limited or outdated information.

What are the rules of thumb?

One of the reasons why rules of thumb can be unreliable is that they may be based on limited or outdated information. For example, a rule of thumb about the stock market that was popular in the 1980s may no longer apply due to changes in the market or economic conditions. Another reason why rules of thumb can be unreliable is that they may oversimplify complex situations. For instance, a rule of thumb about how to succeed in business that focuses solely on working hard may not take into account the importance of networking.

Hence, they are sometimes unreliable for several reasons, such as limited or outdated information.
