Answer:

grafting

Explanation:

The grafting is a horticultural technique that enables us to place a stem of a desired plant into another, more adequate already developed root system. This is done by cutting a branch from the already established plant, on the place of the precisely made cut we joint the desired stem, and then joint them together, be it with wax, mud, or a sellotape. The stem that has been placed on the established plant will be able to get the nutrients from it in this manner and become part of it, but it will produce different fruits from the established plant, it will produce its own fruits. This technique of course works only on plants that are more closely related and belong to the same family.

Andrei [34K]

Answer:

The correct answer would be 2 in 4.

According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.

Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.

Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.

The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.

The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.

Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.

Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.

What do plants and other producers do? How do producers and consumers use it?

Scrat [10]

Answer:

Plants and other producers generate their own energy, which allows them to grow, reproduce, and live. They are the only living organisms on the planet that can produce their own supply of food energy, which makes them unique. They, of course, require sunlight, water, and air to survive.

One group is given a larger dosage than is typically prescribed.
A second group is given a smaller dosage than is typically prescribed
Then results of the groups are compared to each other.

The thing that is missing in this experimental design is a third group who are tested with the typical dosage.
