Answer:

look at explanation

Explanation:

Antibotics don't work against viruses because they only work on bacterial infections. These bacterial infections are very much difgferent than viruses, like c o v i d, the flu, or the common cold.

I am a multicellular organism. I am heterotrophic and rely on oxygen to metabolize my food. I belong to Kingdom

Fynjy0 [20]

Answer:

Kingdom Animalia

Explanation:

Kingdom Animalia is one of the seven kingdoms living organisms are classified into. The Kingdom contains organisms called ANIMALS. They are eukaryotic i.e. possess a membrane-bound nucleus. Animals are heterotrophic i.e. they rely on other organisms for their source of energy (food).

In order to break down this food via metabolism, animals need oxygen to do so. This process is called respiration, and it yields energy in form of ATP, which is used by their cells to carry out cellular functions. Therefore, a heterotrophic multicellular organism that relies on oxygen to metabolize its food belongs to KINGDOM ANIMALIA

g a true breeding pea plant with round and green seeds was crossed to a true-breeding pea plant with wrinkled and yellow seeds.

Sveta_85 [38]

Answer:

The probability of producing a round and green plant from this cross is 3/16

Explanation:

This question involves two distinct genes coding for seed shape and seed colour. In the seed shape gene, allele for round seeds (R) is dominant over allele for wrinked seeds (r), while in the seed colour gene, allele for yellow seed (Y) is dominant over allele for green seeds (y).

A truebreeding plant means that the plant possesses homozygous genotype. Hence, a truebreeding pea plant with round and green seeds will have genotype: RRyy while true-breeding pea plant with wrinkled and yellow seeds will have genotype: rrYY. These two parents will produce F1 offsprings with genotype: RrYy (heterozygous).

When the F1 offsprings are self-crossed (RrYy × RrYy), the following allelic combinations of gametes will be produced by each F1 parent: RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible F2 offsprings with a phenotypic ratio 9:3:3:1 will be produced

9- Round yellow offsprings (R_Y_)

3- Round green offsprings (R_yy)

3- Wrinkled yellow offsprings (rrY_)

1- Wrinkled green offsprings (rryy)
