Answer:

$\boxed{\bold{Abiotic \ Factor(s)}}$

Explanation:

Nonliving part of the environment are abiotic factor(s)

Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Some examples of abiotic factors are wind, sun, soil, rain, water, rocks and minerals. These abiotic factors affect biotic factors because the biotic factors need to survive with these things. Water, sunlight and soil might not be living, but they help other organisms live.

Seed packets give a recommended planting depth for the enclosed seeds. The most likely reason some seeds are to be covered with

dusya [7]

Answer:

The most likely reason some seeds are to be covered with only 1/4 inch of soil is that the seeds require light to germinate.

Explanation:

This seed packets does not say anyhing about temperature so we can rule out higher temperature. It is really rare to plant with seeds does not have any cotyledons and also we can't really know it from the question. Etiolation response can also be found in seedlings also from this question we can't know this for sure.

Only thing that is changes if you cover the seeds with only 1/4 inch of soil is light. If you completely cover this seed with soil it wouldn't grow.

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.
