Cultures of a bacterial species were incubated on the shelf of a refrigerator (5 C), out on a lab bench top (22 C), on the shelf

Setler79 [48]

D) Psychrotrophs.

Explanation:

Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
Halophiles prefer high salt concentration.
Mesophiles prefer temperatures with a average of 37 degree Celsius.
Anaerobes grow in absence of oxygen.
In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.

If a spinach plant with flat (FF) green (GG) leaves is crossed (pollination and fertilization occur) with another spinach plant

never [62]

Answer:

The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.

Explanation:

This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.

According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.

This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
