Why doesn't a spider get stuck in its own web?

One hypothesis, that spiders simply skip over the sticky threads, has been more or less discredited. In fact, orb-weavers sweep their hind legs across the goo hundreds or thousands of times as they make their webs. They also brush their bodies against the drops while they're subduing prey.

spiders don't come into contact with their webs all at once. Instead, they move nimbly along the strands of their webs with only the hairs on the tips of their legs making contact with the sticky threads.

<u>Renaissance women had less freedom than men</u> ↔ Low class women were expected to be housewives and take care of everything to do with the house. Working-class women were expected to help their husbands run their business. They were denied all political rights and considered legally subject to their husbands.

<u>The plague nearly destroyed Italy's economy</u> ↔ It became harder and harder to find people to plow fields, harvest crops, and produce other goods because of the amount of people dying. Peasants also began to demand higher wages. Lasted from 1629 to 1631 and killed more than 45,000 people in Venice alone. It wiped out over half the population.

In garden peas a pure line that is tall with purple flowers is crossed to another pure line that is short with white flowers. Th
defon

Answer:

See the explanation

Explanation:

Answer 1.

As given that in F1 all are short and white then it can be said according to Mendel's law that short and white are dominant over tall and purple.  

Let S for short s for tall and W for white and w for purple allele.

So the genotype of short purple will be Ssww or SSww. So In first case Ssww self crossed then resultant offsprings will be,

................ Sw .................... sw

Sw ........ SSww ............. Ssww

sw ........ Ssww .............. ssww (tall and purple)

So from this 1/4 will be tall and purple while 3/4 will be short and purple.

In second case SSww only short purple progeny will appear.

Answer 2.

2. a) The female progeny will not show any trait because there are two X chromosome in females , so female offspring can be carrier but not show any trait in case of X- linked trait.

2. b) Half of male offsprings show trait because X is inherited from mother. So the chance of having X-linked recessive allele is 1/2.

2. c) The chance of having X linked affect allele in daughter is 1/2. So the chance of inheriting that X to son will be 1/2 so in total there is chance of 1/4 that son will be affected.

2. d) the chance of first child show this trait will be 1/4 in case of male offspring while 0 in case of female offspring.

Hope this helps!

Which is a purpose for which a pedigree chart might be prepared? to determine the gender of a fetus to determine if a fetus has
Anarel [89]
The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait.
This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
