The lizard population on the chart shows it steadily increasing in numbers. This might be because there are less predators and they have more prey to feed on so that their population will thrive.

typical human karyotype has 23 types of chromosomes arranged from largest to
smallest. In males and females 22 of these chromosomes look exactly the same
and they are called autosomes. The 23rd pair of chromosomes is the sex
chromosome which differentiates males from females. Females have 2 copies of
the x chromosome. Males have a copy of both x and y chromosome to make the 23rd
pair. <span>
<span>Chromosomes can also have abnormalities that
result to different conditions and identifiable traits. A most common
chromosomal abnormality is the condition called Down Syndrome, where chromosome
21 has a third copy because of an abnormal cell division.</span></span></span>

Explanation:
Deborah usually have a couple of glasses of wine before beginning to speak in front of large groups. This "medicinal" use of alcohol can be explained MOST easily: By operant conditioning.

Answer:
a. halophilic
Explanation:
Halophilic microorganisms have an absolute requirement for high salt concentration (NaCl concentration). These microbes grow well under the conditions of higher salt concentration but do not survive the lower salt concentrations. For example, the halobacteria are the archaeans that depend on high NaCl concentrations for growth and do not survive at a concentration below about 1.5 M NaCl.
According to the observations, the bacterium could not grow in the tube having a NaCl concentration of 0.5% but exhibits maximum growth under higher NaCl concentrations (15%). This means that the observed bacterium is a halophile or halophilic microbe.
