7. A hen's egg with the shell dissolved is placed in a 10% salt solution. Relative

The links between the energy that carnivores get from eating to the energy captured by photosynthesis.

Reptile [31]

Between every food chain from one animal to another there is 90% energy loss so if a herbivore eats a plant, it will only get 10 joules of energy. and if a carnivore eats the herbivore then it will only get 1 joules of energy. so in every food eaten, there is 90% energy loss.

1. Which aspects of soil do you think are easiest to change? Which are more difficult

Serggg [28]

Difficult to change - nutrients! crops won’t grow on soil that has had all of the nutrients used up. example: after growing corn in the same place for 50 years, corn will not grow anymore because all of the nutrients it needs to grow will no longer be in the soil

In most animals, the ______ state of the life cycle is much larger than the ______ state.

frozen [14]

In most animals, the diploid state of the life cycle is much larger than the haploid state.

The multicellular diploid stage is the most evident life stage in a diploid-dominant life cycle, and the only haploid cells are the gametes. Most animals, including humans, have this kind of life cycle. It is much larger than the haploid life cycle because of the complexity due to diploid stages.

The multicellular (or occasionally unicellular) haploid stage is the most visible life stage and is frequently multicellular in a haploid-dominant life cycle. The only diploid cell in this kind of life cycle is the single-celled zygote. This kind of life cycle is found in some algae and fungi.

Meiosis, which produces haploid cells from diploid ones in all sexually reproducing species, and fertilisation are two examples of fundamental life cycle characteristics that all sexually reproducing species share (the fusion of haploid gametes to form a diploid cell called the zygote).

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.
