Most cacti have extensive, but shallow root systems that allow them to soak up any rainfall that may come their way. specialized stems allow cacti to store water for a long time since rainfall is often sporadic in the desserts.

Answer: Thymus gland

Explanation:

The thymus gland is an endocrine gland that is located in the upper part of the human chest. It is responsible for producing white blood cells. This gland is located near the airway. The enlargement of the thymus gland can suppress the nearby structures. This may result in shortness of breath, and cough along with sputum. The thymus gland produces several endocrine hormones like thymopoietin and thymulin.

The given condition is indicative of the mass of the thymus gland.

Which is identical in all living organisms?

ira [324]

Living things are based on a universal genetic code. All organisms store the complex information they need to live, grow, and reproduce in a genetic code written in a molecule called DNA. That information is copied and passed from parent to offspring and is ALMOST identical in every organism on Earth.

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%.
