Answer:

In my opinion time is something which does not exist, actually everyone in this world has time differently, for them it all depends on relativity.

Time travel may be possible one day but we are very far from it.

you Could fix any problem that happened but what would would happen if that solution became a problem so you wouldn’t fix the first problem so it’s still a problem so for every problem you would have it would keep repeat

Some inbred strains of the weedy plant Arabidopsis thaliana flower early in the growing season, but other strains flower at late

RoseWind [281]

Answer:

a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.

b. The genotype of all the four plants are:

1st plant = Ll

2nd plant = ll

3rd plant = LL

4th plant = Ll

c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).

In case if the 2nd plant is self-fertilized, the expected progeny will be only early.

In case if the 3rd plant is self-fertilized, the expected progeny will be only late.

In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).

What are some seasonal variations and climate changes that can change an ecosystem?

o-na [289]

Seasonal variations of climate impact the state of an ecosystem. In areas that experience a cold season, some elements of the ecosystem change their residence or even hibernate to survive. Succession can be considered a higher state of development of the ecosystem.

Good luck!

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by

bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

--------------------------

Available data:

Population size, N = 100 tigers
Number of Tigers with horizontal stripes = 30
Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.

Monosaccharides from polymers through the formation of ———— bonds

Alex_Xolod [135]

Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
