They are less likely to be separated during crossing over.
A is prophase
B is prometaphase
C is metaphase
D is anaphase
Answer:
*Sensory adaptation* is the common adaptation in all three sense. Sensory adaptation is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. All senses are believed to experience sensory adaptation.
Explanation:
This adaptation is shared as well as used differently as explained below.
1) Hearing+balance :In terms of hearing, our ears adapt to loud sound as it hits the small bones located in the inner ear. The loud sound leads the inner ear bone/s to contract. This contraction causes the reduction or delay of transmission of sound vibrations to the inner ear. Detection of the vibrations follows. However, this process of auditory adaptation usually does not work very well with loud sounds that are sudden or instantaneous. Examples of these sounds are gun shots or explosions
2)Smell :Low concentrations of several chemicals present in the air can be detected by the sensory receptors in the nose. These chemicals that we quickly detect include those in perfumes or air fresheners
Answer:
Explanation:
An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.
Answer:
These bands represent different confirmation of DNA
Explanation:
pGLO DNA is a plasmid DNA that is used as a vector for genetic engineering. Plasmid DNA is found in supercoiled confirmation in vivo. The double helix forms extra twists to easily fit inside the cells. During isolation of plasmid from the cell, nicks can be introduced in the DNA due to harsh isolating methods or contamination by nuclease. As a result the supercoiled confirmation is changed into circular confirmation. It is bulkier than the supercoiled form and travels more slowly. When both DNA stands get cut at the same place, the DNA gets liner confirmation. In the end, supercoiled DNA runs the fastest on gel followed by linear DNA and then the circular DNA.
