Which is a disadvantage of using DNA technology?edible vaccines
phytoremediation
herbicide tolerance
gene transfer to nontarget species

Answers

Answer 1

Answer:

Answer:

The answer is D. Gene transfer to non-target species.

Explanation:

Using DNA technology we have made several genetically modified crops called GM crops. But sometimes the transgenic trait or gene may effect the non-target species. For example Bt-crops were found damaging the soil health. These pest resistant Bt-crops release Bt toxin near the soil root zones. High levels of Bt toxin can affect the health of soil as well as the soil insects. Hence GM crops must be monitored for the effects on non-target species.

Answer 2

Answer:

Answer:

The correct answer is: Gene transfer to non-target species. It is believed within the scientific field that these risks directly affect environmental impacts and need to be assessed on a case by case basis and recommended post-release ecological monitoring.

Explanation:

Transgenic crops could possibly entail positive or negative indirect environmental effects through changes in agricultural practices such as pesticide and herbicide use and cropping patterns. Agriculture affects the environment it does not matter which type we are talking about. Then it is normal to conclude that the use of new genetic techniques in agriculture will also affect the environment.

The main difference between the nebular and condensation theories is that the condensation theory stresses the importance of _____ to the formation of planets. a nebular cloud interstellar dust a flattened disk plane nuclear fusion

Answers

The main difference between the nebular and condensation theories is that the condensation theory stresses the importance of interstellar dust to the formation of planets.

Interstellar dust is a significant component of the galaxy. It is produced in many various locations in the universe such as in the cooler outer layers of red giant stars where it is eventually blown off by the solar winds and it can also be produced in the expanding shell of gas residue from a supernova remnant. The central part of the interstellar dust is enclosed by ice and it is made up of either silicates or metals or at times a little of both.

Asexually, fungi can reproduce by fission, fragmentation, budding, or _____. producing spores mitosis meiosis

Answers

Answer : The correct answer for the blank is -

Producing spores.

Fungi is a separate kingdom of multicellular eukaryotic organisms that are different from plants and animals.

By asexual reproduction, they produce large number of genetically identical, haploid reproductive cells, called spores.

Spores are spread through wind and under favourable conditions, they germinate to form new fungi.

Thus, producing spores is the right answer.

The answer is: Producing spores.

The diagram below shows a helium atom.The particles labeled A are called (2 points)

A) Electrons

B) Protons

C) neutrons

D) nucleus

Answers

Particular A shown in the image is called protons, as option B shows.

What are Atoms?

It is the basic unit of matter.
It is a particle composed of electrons, protons, neutrons, nucleus and electrosphere.

An atom of any element is made up of a nucleus and an electron shell. In the electrosphere, there are small particles with a negative charge. These particles are called electrons.

In contrast, the nucleus has two types of particles, protons that have a positive charge and neutrons that have no charge.

Therefore, when we observe the image shown in the image above, we can see that there are particles with a positive sign, inside the nucleus of the atom. These particles are protons.
