Answer:
reduction in potential medicines
reduced food supply
Explanation:
The direct consequences of a decrease in angiosperm's biodiversity is a reduction in potential medicines and food supply.
Angiosperm biodiversity (the flowering plants) act as a source of food to several living organisms, including human. This is evident in the practice of farming by humans. Different categories of consumers in the ecosystem depends largely on flowering plants for their food either directly or indirectly.
They also serve as a source of medicine. For example, chloroquine which use to be the major drug against the treatment of malaria was extracted from a flowering plant known as <em>Chinchona pubescens.</em>
<em>Several species of flowering plants remains in the wild whose usefulness are yet to be researched. They represent a source of future food and medicine for man and animals.</em>
<em>Hence, if the diversity of flowering plants is reduced, it is going to have direct consequence of reduction in potential foods and medicine.</em>
Answer:
the reporter gene can randomly insert near to an enhancer sequence which can induce its expression
Explanation
Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.
Answer:
a. DNA polymerase proofreading: consequence of its absence is the DNA mutation
b. Mismatch repair enzymes
: consequence of its absence impedes homologous recombination resulting in the final mutation
c. Nucleotide excision repair enzymes
: the absence of nucleotide cleavage repair enzymes would impede the functioning of damaged DNA repair mechanisms
Explanation:
a. DNA polymerases are the enzymes that form the DNA in cells. During DNA replication (copying), most DNA polymerases can "check their work" with each base they add. This process is called review. If the polymerase detects that you have added a wrong nucleotide (incorrectly paired), remove it and replace it immediately, before continuing with DNA synthesis
b. In homologous recombination, the information from the homologous chromosome that matches that of the damaged one (or from a sister chromatid if the DNA has been copied) is used to repair the fragmentation. In this process the two homologous chromosomes are approached and the undamaged region of the homologue or the chromatide is used as a template to replace the damaged region of the broken chromosome. Homologous recombination is "cleaner" than the union of non-homologous ends and does not usually cause 11 mutations
c. Excision repair: damage to one or a few DNA bases is usually fixed by removing (excising) and replacing the damaged region. In repair by base cleavage, only the damaged base is removed. In nucleotide excision repair, as in the mating repair we saw earlier, a nucleotide section is removed
Answer:
What is the relationship between increased carbon in the ocean and increased carbon in the soil?
How else might carbon be transferred to soil? Direct because as you increase 1 you increase the other due to the terrestrial plant and oceanic plankton requirements of water, nutrients and CO2.

Hope this <em><u>Helped!</u></em> :D
Taphonomists would probably conclude that hominins had scavenged meat from an animal carcass, they did not kill if fossil animal bones; did not contain stone cut marks, which are easily distinguishable from tooth marks.
Some characteristics that have distinguished hominins from other primates, living and extinct are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use, and in some cases communication through language.<span />
