Answer:
Tt Rr WW
Explanation:
Given:
1. tall (T) is dominant to short (t)
2. red flowers (R) is dominant to white flowers (r)
3. wide leaves (W) is dominant to narrow leaves (w)
4. Also, a tall, red, wide-leaved plant is crossed to a short, white, narrow-leaved plant
To find: genotype (with correct arrangement of alleles) of a tall, red, wide-leaved parent
Solution:
Genotype (with correct arrangement of alleles) of a tall, red, wide-leaved parent is Tt Rr WW
Answer: One thing that is NOT true that concerns conifers is <u>they have motile sperm. </u>
Explanation:
Conifers are a seed plant. They are usually trees that bear cones and they have vascular tissues. They are classified as gymnosperms. The living confers are all woody plants.
The trees that are conifers are;
- Junipers
- Cedars
- Cypresses
- Firs
- Kauris
- Redwoods
- Spruces
- Yews
The colors of these conifers vary and include colors such as rainbow, bronze, yellow, blue, and red.
Answer: Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers. When small organic molecules are joined together, they can form giant molecules or polymers. These giant molecules are also called macromolecules. Natural polymers are used to build tissue and other components in living organisms.
Generally speaking, all macromolecules are produced from a small set of about 50 monomers. Different macromolecules vary because of the arrangement of these monomers. By varying the sequence, an incredibly large variety of macromolecules can be produced. While polymers are responsible for the molecular "uniqueness" of an organism, the common monomers are nearly universal.
The variation in the form of macromolecules is largely responsible for molecular diversity. Much of the variation that occurs both within an organism and among organisms can ultimately be traced to differences in macromolecules. Macromolecules can vary from cell to cell in the same organism, as well as from one species to the next.
Explanation:
For him they were just discrete physical units of inheritance. Johanson coined the term "gene" and people started calling them genes. Today for us these factors are parts of DNA, the base sequences that carry the biological information to determine a trait. Mendel factors are alleles of genes.
Answer:
MNP stands for the most probable number which is used for finding out the concentration of viable bacteria in a sample. It is commonly used to check the quality of water and its safety. Usually, the presence of fecal coliform bacteria is checked in this test.
Principle of MNP: The sample which is to be tested is diluted serially and then inoculated into a broth medium containing lactose. If coliforms are present in the tube than it will consume lactose and release acid and gas.
Color change represents acid production and gas trapped in the Durham tube represents the gas production by bacteria. Then the number of tubes at each dilution that showed positive results are compared with standards to determine the most probable number of the bacteria.
