A breeder wanted to create a new variety of potatoes that produces more of the vitamins found in the roots of carrots than in typical potatoes. What method of selective breeding would the breeder most likely use?a. inbreeding
b. hybridization
c. hand pollination
d. genetic engineering

Answers

Answer 1
Answer: I believe the correct answer is D. genetic engineering. So this person wants to have the best qualities of both potatoes and carrots. In order to have that, he needs to take the genetic material of potatoes and that of carrots, mix them, and create something new that will have the characteristics of both of these vegetables. This means that he would be genetically engineering both plants.
Answer 2
Answer:

on ed2020, the answer is D.(genetic engineering)

A new highly nutritious crop is going to be planted in an area where it has never been planted before. Which is the most likely outcome of such an event?

Answers

When a highly nutritious crop is newly planted in an area where it has not been planted before, the effect is positive which can change the local biodiversity. This is because a nutritious crop cannot do any harm towards the area and the good thing is the area with no crop of this kind in the past can have new kinds after planting this.

It leaves form Plymouth Harbor, toured around theMadeira and Canary islands and made a landfall at the Cape of Verde islands. Theexpedition was originally planned to end in two years. It got delayed andturned into five years due to Darwin spending most of his time exploring onland. the answer is D.

. Alpha Particles a. What is the mass number of an alpha particle? b. What is the identity of an alpha particle? c. What kind of charge does an alpha particle have?

Answers

Answer:

Alpha particles are usually produced by alpha decay which consisted of two protons and two neutrons.

They are identical to the nucleus of helium-4.

The alpha particle is represented as α or α²⁺. In addition, as it is identical to nucleus of helium, it is also represented as He²⁺.

As it only posses two protons and two neutrons but no electrons, the overall charge of alpha particle is +2.

The mass number of an element refers to the total number of neutrons and protons in the nucleus. Hence, the mass number of alpha particle would be 4
hope it helps you 
an alpha particle is basically a helium nucleus...so it contains 2 protons and 2 neutrons. So atomic mass number is 4..I.e. 2 protons + 2 neutrons
