can someone calculate the genotypes and phenotypes of this pls

Answers

Say this was about breeds of chicken nuggets, some with and some without these features, then we can say that the genotypes of this nugget must be just that, mostly nugget, but due to certain influences, there will be some part that is not just nugget, so:

More than 80% nugget

Less than 20% non-nugget genotype.

This means that the phenotype, that shows up, is something similar to this: a mostly nugget being.

Phloem delivers the sugar made during photosynthesis to various parts of a
plant. Some food energy is converted into ATP for uses during plant activities such
as phototropism. Which two plant systems are interacting in this scenario?
A:Transport and response.
B:Reproductive and transport.
C:Reproductive and response.
D:No plant systems are interacting.

Answers

The two systems in plants that are interacting when sugars are delivered to different parts and when plants respond to light would be transport and response.

Transportation and tropism in plants

Synthesized foods in the form of carbohydrates are transported from sources to sinks in plants through the phloem. This form parts of the material's transportation system in plants generally.

The transported foods are used to generate ATP during respiration. ATP is spent when plants respond to external stimuli such as water, light, objects, etc. Response to external stimuli in plants is known as tropism.

Why is a series circuit not a good way to wire a house? Question 5 options: Any break in a series circuit, such as a burned-out light bulb, will turn it into a parallel circuit. Any break in a series circuit, such as a burned-out light bulb, will result in overloading all the other light bulbs. Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit. Any break in a series circuit will result in a fire.

Answers

The correct answer is option Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit as it explains the disadvantage.

A downside of collection circuits is if there may be a ruin or fault at any of the home equipment related to the circuit, the last home equipment could be reduced from the supply. Regarding parallel circuits, home equipment may be related and disconnected to the circuit without affecting different components of it.

What will happen if the bulb will burn out?

if one bulb burns out in a sequence circuit, then this could ruin the circuit. This is due to the fact each tool in a sequence circuit needs to paintings well for the circuit to be complete. Unlike in a parallel circuit - in which every mild has its personal circuit - so despite the fact that one bulb burns out, the last bulbs will nevertheless function.

Hence concluded that  Any break in a series circuit, such as a burned-out light bulb, breaks the entire circuit can cause severe damage.
