B. Flowering seed plants
C. Ferns and fern allies
D. Echinoderm
What organisms are insects closely related to?
A. Crustaceans
B. Mollusks
C. Segmented worms
D. Chelicerates
Answer of Q.1. is:
C] Ferns
While, Answer of Q.2 is ;
B] Mollusks
B. Prokaryotic
C. Nucleus
Prokaryotic cell don't have any membrane bound organelles but they do have a nucleus. Thus, the correct option is B.
Prokaryotic cells are defined as the cell which single-celled, non bound organelle microorganisms known to be the earliest on earth. Prokaryotes comprises bacteria and archaea.
The photosynthetic prokaryotes comprises cyanobacteria that perform photosynthesis. A prokaryotic cell comprises of a single membrane and hence, all the reactions occur within the cytoplasm. The below diagram shows a prokaryotic cell.

Little Bear's porridge in the Goldilocks tale, abiotic elements must be just right for life to grow.
Thus, Many creatures also need a certain collection of abiotic elements in order to flourish. a snake residing in the arid region of Arizona. It can move through sand and loose soil by twisting its body, therefore it is at home in that dry environment.
Additionally, it can escape the heat by slipping under rocks.
Some snakes are also nocturnal, meaning they spend the most of the day sleeping and doing their activities at night when the sun is not out. a person picking up one of these snakes with desert adaptations and setting it atop a snow-capped Himalayan summit.

The scientists A(Francis Crick) C(James Watson) concluded that DNA is a three-dimensional molecule.
Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
Therefore, DNA is made up of a chain of molecules called Nucleotides. Each nucleotide contains a nitrogen base, a sugar group and a phosphate group. Four possible nitrogen bases can be present in DNA; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). Human DNA contains billions of DNA bases.
