Answer 1:
The corret option is that they have same properties.
Reason:
According to Dalton atomic theory an element is made from identical atoms having same chemical properties but different physical properties.

Answer:
The correct option is that boronhas a larger radius and the proton in carbon exert a greater pull
Reason:
According to trends in periodic table if move from left to right of periodic table along rows, nuclera charges increse as a result atomic radius decreases. Boron is present in group 3rd A while carbon is present in group 4th A. Thats why boron has has a larger atomic radius and carbon has smaller atomic radius due to greater nuclear charges.

The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square
Fudgin [204]

Answer:

A Punnett square is shown. The columns are labeled Upper D and d. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, d d, d d, Upper D d.

Explanation:

Punnett square is used to depict the cross between two organisms. Progeny genotypes can be determined by punnett square. Columns and rows are labelled according to the alleles present in the genotype of respective parents, in this case the mom and the dad.

It has been given that the mom is heterozygous for dimples trait. Since, heterozygous genotype has two different alleles together, mom's genotype must be Dd. Dad is homozygous for no dimples so he can either be DD or dd depending on the dominance nature of the trait. Out of the given options, only the selected option has one heterozygous genotype (Dd) and one homozygous genotype (dd) together hence it is the correct option.

Could ash be harmful to an environment?
weeeeeb [17]
Ash can be harmful to an environment. It mostly depends on how much ash there is though. If a volcano erupted such as Mt. St. Helen's then yes that can harm an environment. Ash can cover the sky and block out the sun for days before disappearing and that will affect the life of plants
