Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space

Question: How is wind speed and direction related to air temperature?

Bad White [126]

Answer:

The wind moves from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses

Explanation:

Relationship between wind speed and direction to air temperature:

wind flows from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses.

A. The land air will heat up more during the day. This is because the land has a lower specific heat capacity than water, hence increases a lot more rapidly in temperature than the sea when the sun comes up.

B. The air packet over the land will cool down more rapidly at night due to the lower specific heat capacity of land when compared to the sea.

Consider a cross between a plant with two flower colors, yellow and red. Yellow (Y) exhibits complete dominance over red (y). It

Aneli [31]

Answer:

1) option a is correct. (260+270)/1545

(Note about this option: In the statement, it is written as (260+270) 1545. Lacks the division symbol, / )

2) From these results one can conclude that the two genes are linked (option a)

Explanation:

To know if two genes are linked, we must observe the progeny distribution. If heterozygous individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, phenotypes appearing in different proportions, we can assume linked genes in the double heterozygote parent.

We might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny. Phenotypes with the highest frequencies represent the parental gametes.

To calculate the recombination frequency, we will use the following formula: P = Recombinant number / Total of individuals.

In the present example:

Parental) YySs x yyss

Gametes) YS parental type ys, ys, ys, ys

ys parental type

Ys recombinant type

yS recombinante type

The total number of individuals in the offspring: 1545

Phenotypic class Number of offspring

500 Y-S- (parental)
515 yyss (parental)
260 Y-ss (recombinant)
270 yyS- (recombinant)

According to this information, the phenotypic frequencies of the progeny differ from the phenotypic ratio 1:1:1:1. We can assume then, that these genes are linked.

The recombination frequency is:

P = Recombinant number / Total of individuals

P = 260 + 270 / 1545

P = 530/1545

P = 0.343

The genetic distance between genes is 0.343 x 100= 34.4 MU.
