Readme [11.4K]

Answer: When the food is not going thru a factory or GMOs are added.

Explanation: Usually any food that is from a farm like butter and so are went thru in a factory which can affect our health because it is bad to have artificial flavors added instead of keeping it non-artificial and even worse when GMOs are added that effects the earth. it hurts the plants and wildlife.

Hope this helps :).

How can people preserve genetic variety in plants grown by grafting or splicing?

dolphi86 [110]

There are many reasons are specific to the plant and our needs but remember this, without us modifying plants we would have been extinct thousands of years ago, everything you eat today does not exist in nature and if it does exist is either inedible, toxic, or too small to provide important nutrition.

<h3>What is grafting?</h3>

When the tissues of plants are joined together to let them continue their growth together as one, then such a practice is known as grafting.

Grafting is commonly practised in horticulture and agriculture for the growth of commercially important plants in an asexual manner.

In the process of grafting, the upper part of the combined plant is known as the scion and the lower part is known as the stock.

Thus, this could be the answer.

Compare and contrast the way in which moons and ring systems form

Stella [2.4K]

Answer:

In addition to their moons, all four of the giant planets have rings, with each ring system consisting of billions of small particles or “moonlets” orbiting close to their planet. Each of these rings displays a complicated structure that is related to interactions between the ring particles and the larger moons.

The allele (AA, Aa, or aa) combinations are achieved through what process?

Ipatiy [6.2K]

Answer 1-

<u>Mendelian </u>

The different allelic combinations are made by the process of mendelian inheritance. This happens before cell division.

Answer 2-

<u>25% </u>

In a monohybrid cross, there are four boxes, and thus each box denotes 25% share.

Answer 3-

<u>75% </u>

The cross between Pp and Pp will look like the image shared below. Here, PP and Pp will show dominant trait. Since, it is 3 out of 4 boxes, it will be 75%.

Answer 4-

<u>100 </u>

The punnett square for this cross RR and WW is shown below. Since all the offsprings are RW, therefore it is 100% pink flowers.

Answer 5-

<u>Tt </u>

Since it is a case of dihybrid cross, the gametes formed from TtHh would contain both the alleles. The possible gametes would be TH, Th, tH and th.

Answer 6-

<u>aabb </u>

In any dihybrid cross with dominant alleles, the probability of getting aabb would be the least.

Answer 7-

<u>56% </u>

In a cross AaBb and AaBb, the probability of getting both dominant traits- round and yellow, would be 56%
