Answer:
TT * Tt
Tt, Tt, TT, TT
Explanation:
Given -
Patrick is homozygous for tall head
Patricia is heterozygous for her tall head
The little baby Patty has a short head
Let us assume that the traits for short head is represented by "T" and trait for tall head is represented by "t"
Genotype of Patrick is "TT"
and genotype of Patricia is "Tt"
On crossing Patrick and Patricia, following offspring are produced -
TT * Tt
Tt, Tt, TT, TT
Out of four two are heterozygous tall headed and two are homozygous short headed.
Answer: The correct answer for the fill in the blank is- May be placed in the Plantae kingdom.
An organism that produces food by photosynthesis can belong to three kingdoms that are Monera ( example- cynobacteria) , Protista ( example- algae) and Plantae ( example- green plants).
Thus, it is not necessary that the organism must be placed in Plantae kingdom as it may belong to any of these three.
Organisms belonging to Animalia kingdom do not perform photosynthesis.
Thus, second option is the right answer.
Answer:
A.) NO₃⁻
Explanation:
NO₃⁻ = nitrate
NO₂⁻ = nitrite
NH₃ = ammonia
N₂ = nitrogen (nitrogen naturally exists as a diatomic molecule)
Sinkholes one major environmental risk of underground mining because, Underground mines may collapse after mining is complete, which causes sinkholes.
<u>Explanation:</u>
The movement that occurs on the surface of the ground is known as mine subsidence. This is mainly caused due to the collapse that happens in the cola or any clay mining works that occurs in the underground surface. When anything is extracted form the underground surface, some holes are made in the underground surface which are sinkholes.
The damages that are caused as a result of this can be claimed by Mine Subsidence Insurance Policy. This type of underground mining is very dangerous as it give rise to the formation of sinkholes. This is forms when there is collapsing of the surfaces in the underground occurs after the completion of the mining work.
I believe it is A beacuse nucleotides come from the word nucleus.
