Frog temperature. Frogs are ectotherms, this means they gettheir heat from external sources. They are sometimes called 'cold blooded', but in fact they do not have cold blood, it is justregulated by their environment. In comparison, humans are endotherms and can maintain their body temperature at about 37°C.

Amphibians are ectothermic or cold-blooded. This means that they do not maintain a constant body temperature like endotherms (like humans) do. The amphibian’s body temperature is controlled by the surrounding environment and nearly matches that temperature. Amphibians behaviorally will move or do activities to adjust their body temperature. For example, if they are too hot they will move to the shade and if they are too cold they will move to a sunny area. Some frogs secrete fluids to help maintain their moisture and temperature in extreme environments or conditions.

In some species of Drosophila, there are genes on the Y chromosome that are not on the X chromosome. Imagine that a new allele a

mr_godi [17]

Answer:

True

Explanation:

The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.

However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.

Thus, true is the correct answer.

the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.

Mitosis & Meiosis: Thinking Scientifically

REY [17]

Answer:

65536 cells

Explanation:

starting from 1 cell at zero minutes there will be 1 (2^0) cell; 2^0 = 1

after 15 minutes there will be 2 (2^1) cells

after another 15 minutes ( 30 min) there will be 4 ( 2²) cells

after another 15 minutes ( 45 min) there will be 8 (2³) cells

after n number of 15 minutes there will be (2^n) cells

calculate number of 15 minutes in 4 hours

4 hours = 4 × 60 minutes

number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16

using the formula above and substitute 16 for n in the formula

Number of cells = 2 ^n = 2^16 = 65536 cells
