Answer: A. Carbon footprint

Carbon footprint can be defined as the amount of carbon released as a gas in the atmosphere by particular human activity. The carbon dioxide and carbon monoxide are gases in the atmosphere, which are causing the increase in the temperature of the global climate. Human activities like deforestation, burning of fossil fuels and green house effect has led to the increase in the carbon gases in the atmosphere, resulting in global warming. Hence, carbon footprint should be considered for resolving the problem of global warming in the world.

9966 [12]
<span>The graph portrays predation. The relationship shows that an increase in the population of zebra results in a subsequent increase in the lion population, and vice versa. This, therefore, means that the lion population is dependent on the zebra population due to an interaction (predation).  The lion population will always be lower than that of the zebra because of the inefficiencies of energy transfer up the trophic levels (exhibited by a typical energy pyramid).  </span>

A template dna strand contains the sequence 3'-atgctgac-5'. the corresponding sequence in the rna transcript is:
V125BC [204]
The corresponding sequence in the RNA transcript is 5'-UACGACUG-3' . One of the differences between DNA and RNA is the fact that the RNA contains the base uracil instead of thyamine. The base pairing occurs between A and T, and G and C. DNA undergoes the process of transcription in the nucleus to generate RNA, which then undergoes translation (for mRNA) in the cytoplasm to yield proteins.

A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (
Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Chi Square test

See the attached file

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97
