Add 2 electrons to carbide atom make it neutral because there are two unpaired electrons present in the carbide atom and it has -2 charge. So the carbide required two electrons for pairing and make the carbide atom neutral. for adding two electrons its all unpaired electrons paired to other two electrons which complete its valency and make it a stable atom.

ICE Princess25 [194]

Post flyers around the city - would be best way to promote the use of solar power as a sustainable energy source for the businesses in the city.

Explanation:

Spreading awareness is the best way to promote the use of solar power as a sustainable energy source for the businesses in the city.

The solar flyers would give all the necessary basic details that anyone would want to know about it. Various business enterprises in the city can look into the basic details and inquire the correct person to be contacted for expert solutions. The flyers will provide basic instructions about how to get the solar power connections in a shortened version detailing its benefits like the basic tax cuts for upgrading to solar power, any rebates for installation charges etc.

This would be the first step that Alan can do as a council member to promote solar power in his city. Further he can also conduct various surveys and workshops and offer tax incentives to implement solar power successfully in his city.

Not all plants are vascular, for example mosses. They don't have specialized system for transport of water and solutes. Therefore, Option 1 is false.

Only bacteria, protista and yeast are unicellular. Rest all the organisms are multicellular. Thus option 2 is true.

Only bacteria are prokaryotic, rest all organisms are eukaryotic, including all the plants. Option 3 is true.

Plants are the only organisms which are autotrophic. Although apart from this mode of nutrition, plants can be parasitic or carnivorous as well. But primarily they all are autotrophic. Option 4 is true

Not all plants need sunlight, some get energy from the chemical substances from their surroundings. Option 5 is False.

In which situation could a mutation be passed on to the offspring in an organism?

Goryan [66]

Answer:

A mutation could be passed on to an offspring by inheritance.

Explanation:

These 4 scenarios that can occur are autosomal dominant, autosomal recessive, x-linked dominant and x-linked recessive. Autosomal dominant is when both parents have the disorder and pass it on to one of their children but not the other. This means that both parents are heterozygous. Heterozygous is a when a gene has one dominant allele and one recessive allele. Autosomal recessive is when both parents don’t have the disorder but one of their offspring do. This also means that both parents are heterozygous. Next is X-Linked dominant. This can occur when one of your grandparents has the disorder and passes it on to your dad and as a result all of his daughters are affected. Lastly, X-Linked Recessive is similar but it’s the mother that gets the disorder and passes it on to her sons. This process can really help determine whether or not your child has a disorder and is completely healthy.
