Answer:
A living organism's position in the flow of energy through an ecosystem.
<span>There is an EE possibility, 2 Ee's and 1 ee. For the earlobes to be not detached, it would have to be ee, as attached earlobes are recessive. and 1 out of 4 options is ee, so 3 out of 4 options would lead to detached earlobes

Answer:
It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)
Explanation:
The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.
The right answer is Scientists should conduct long-term studies of DNA technology to determine the consequences.
DDT is a potent insecticide: it kills by opening the sodium channels of insect neurons, destroying them instantly, leading to spasms and then death. Some genetic mutations acting on the sodium channels can make some insects resistant to DDT and other insecticides working on the same principle.
The US Environmental Protection Agency has categorized DDT into the B2 class, that is, potential carcinogen for humans. This supports the fact that the insecticide acts on human DNA.
Low molecular weight heparin is associated with less thrombocytopenia than the normal heparin. Low molecular heparin also prevent unnecessary bleeding since it is not as strong as the normal heparin. Low molecular weight heparin are derived from smaller polysaccharide chain and their effect is more predictable than the normally unfractionated heparin. It also help treat deep venous thrombosis, which is commonly associated with prolonged sitting and standing. It is also used to treat pulmonary embolism especially the more massive one. However, care must be observe in using it since some patients elicit allergic responses to it.
