Biology

kari74 [83]3 years ago
3 0

Answer:

Ratio = 9 : 2

Explanation:

We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.

First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:

Resistance (Equivalent) = R₁ + R₂ = 6 ohms

When these are connected in parallel, equivalent resistance becomes:

1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4

1 / Resistance (Equivalent) = 3/4

Resistance (Equivalent) = 4/3

Ratio = R(Series)/ R(Parallel)

Ratio = 6 : 4/3

Ratio = 18 : 4

Ratio = 9:2

A natural phenomenon that typically influences climate over a period of one to two years is _______.
Andrews [41]

A natural phenomenon that typically influences climate over a period of one to two years is sulfur-rich violent volcanic eruption.

Without any doubt, the most plentiful volcanic gas from a volcanic eruption is water vapor, which is non-dangerous.

Nevertheless, notable volumes of carbon dioxide, sulfur dioxide, hydrogen sulfide as well as hydrogen halides can also be released from volcanic eruptions. This natural phenomenon generally influences climate over a period of one to two years.

The sulfuric acid creates a mist of minute droplets in the stratosphere that reflects the incoming solar radiation, an thus is responsible for cooling of the Earth's surface.

These droplets can stay in the stratosphere for about three years, circulating all over through winds and resulting in consequential cooling all over the world.

Discuss the effects of binary fission and short generation time on the accumulation of mutations in a bacterial population over
scZoUnD [109]

Due to the <u>mutation </u>accumulation, the <u>binary fission</u> in bacterial population will decrease due to in ability to divide (Due to inactive replicating enzymes). In the similar way, the <u>generation time</u> will also decrease.

Binary Fission- Binary fission, also known as asexual body division into two new bodies, When an organism divides into two halves (cytokinesis) by binary fission, it doubles its genetic material, or DNA, with each new creature acquiring one copy of the latter.

Generation Time- The amount of time it takes for a colony of bacteria to double in size is known as the generation time. The generation period for various bacteria ranges from a few minutes to many hours. Bacteria multiply by geometric progression because of binary fission.
