Oksana_A [137]

Answer:

D. Psychrophile

Explanation:

Psychrophiles or cryophiles are a type of extremophiles i.e. they live in extreme environment. They grow well in low temperatures ranging from -20 to +10 degree Celsius.

Here, the bacteria was incubated at different temperatures. It did not show growth at standard incubation temperature of 37°C which indicates that it might be an extremophile preferring either very hot or very cold environment. But it also did not show growth at 50°C which means that it does not survive well at high temperature.

Lab bench top has generally colder surface compared to the surrounding environment and a little growth was observed there which indicates that this bacteria might require cold temperature for growth. The result was finally confirmed with abundant growth observed inside refrigerator which is only possible if it is a psychrophile.

A heterozygous woman for both traits (RrFf) marries with a man with no freckles (ff) who can't roll his tongue (rr).

The cross is: RrFf X rrff.

The woman can produce the gametes <em>RF, Rf, rF </em>and <em>rf</em>

The man can only produce <em>rf </em>gametes.

<u>The possible offspring that can arise from the combination of those gametes is:</u>

  • 1/4 RrFf Freckled, tongue-rolling
  • 1/4 Rrff Freckled, unable to roll tongue
  • 1/4 rrFf Not freckled, tongue-rolling

Julli [10]

<em>Fragmentation of forest involves breaking of large continuous forests into smaller, ecologically less diverse units</em>. This often happen as a result of human factors such as road construction, agriculture, building construction, and so on.

Forest fragmentation has several effects including, reduction in forest's health, degradation of habitats loss of biodiversity, among others.

Hence, the best mode of action is for the urban planner to build the homes clustered together on one side of the forest to avoid fragmenting the forest.
