Answer:
C. Mendel hypothesized that the traits of pea plant offspring are inherited.
Explanation:
A. After years of research, Mendel identified the genes for flower colors. False. During Mendel's research, genes were not yet discovered.
B. Mendel bred various dog breeds to discover the science of genetics. False. Mendel worked with pea plants, not dogs.
C. Mendel hypothesized that the traits of pea plant offspring are inherited. True. Mendel uncovered the main principles of the inheritance of simple traits.
D. Using Punnett squares, Mendel developed the principles of genetics. False. The Punnett square was invented by Reginald C. Punnett,
Explanation:
The half life is the time taken for a half of a radioactive material or substance to decay to half.
After the passing of the half-life, only half of the original material will remain. Now, let us follow the half-life sequence of this decay;
One half-life
Original: 1000cm
one half life = 500cm
Two half-lifes
Original: 500:
half-life = 250cm
Three half-lifes
Original : 250cm
Half life = 125cm
Four half-lifes
Original: 125cm
Half life = 62.5cm
Five half-lifes
Original: 62.5cm
Half-life = 31.25cm
Six half-lifes
Original: 31.25cm
Half-life = 15.625

It begins with the unzipping of the double helix by
helicases. Unzipping forms y-shaped replication forks
exposing promoter regions (TATA regions) where the initiator proteins and factor bind to
the regions of DNA. A primer also
attaches to the region. DNA polymerase then
binds to the regions and begins adding DNA nucleotides
to the 3’ end of the primer based on the nucleotides on the template strand. Topoisomerase continues to unwind the DNA as the
polymerase progresses to the end of
replication.
<u>Answer</u>: Aerial roots allow the orchid to attach itself to trees.
<u>Explanation</u>:
- The roots of the plant that grow above the ground are known as aerial roots.
- These aerial roots are found in orchids to attach to the tree.
- The plant may or may not retain its terrestrial root.
- Examples of the orchids with aerial roots are climbing orchids and epiphytic orchids.
- These roots help the plant to firmly stay on the branches of the trees and compete with others for sunlight .
