Answer:DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
Explanation:
Answer:
1) 5 kingdom system of classification is a type of classification in which all the living organisms are classified into 5 kingdoms i. e. protista, monera, fungi, plantae and animalia.
2) Plants are autotrophic organisms while animals are heterotrophic. Plants have cell wall while cell wall is absent in animal. Plants are fixed while animals move from place to place.
3) Both plants and animals are made of cell. Both plants and animals are multicellular organisms. Both plants and animals reproduce.
4) Plants make their own food while fungi are unable to make their own food. Plant cell wall is made of cellulose while fungi cell wall is made of chitin.
I believe the answer is C but I’m not completely sure
Answer: Pulmonary artery
Explanation:
All arteries carry blood away from the heart while all veins carry blood to the heart. With the exception of pulmonary artery, all arteries contain oxygenated blood while all veins except pulmonary vein contain deoxygenated blood.
Thus, pulmonary artery is the answer

Explanation:
Hi there!
We are given the hair types of two cats
The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair
The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt
Please see below for the Punnett Square
Hope this helps! :)
