Answer:

Uncomfortable heat and humidity

Explanation:

After it rains for a long time, the humidity level rises, and most of the time it also brings heat with it. The author was using the metaphor of the broccoli being dropped into a steamer to explain the heat and humidity outside.

Hope this helps :)

Spiders use their silk to build strong webs, to trap bugs, to save themselves from falling, to wrap their eggs safely, and even

Answer:

The missing word is things.

However, the real question is how one material can serve so many purposes? That is what makes it possible for the spiders web to have a high "utility" value?

The answer is in how the spiders make the silk.

Explanation:

So it interesting to note that spiders do not make only one kind of silk. They vary depending on what purpose it's doing serve.

The most common type is Dragline Silk.

Dragline Silk: This contains spidroins. Spidroins fall under a category of a protein called scleroproteins. Because of its composition, a strand or fiber of Dragline has the same tensile strength as steel albeit more flexible. That is if one produced steel the diameter of a spider's silk, and compared both for strength, the silk will be stronger.

The spider produces Dragline silk in its silk glands where they are as viscous as a paste. From here is pulled out or extruded into lines of silk.

Other types of spider silk are:

Capture-spiral silk. Also known as the Flagelliform, they are used for securing lines of the web. They are adhesive, very elastic, and possess high tensile strength.
Tubiliform silk: They are also called Cylindriform. Its main use is for the protection of spider eggs. It is used to make a sac for which protects eggs. This type of silk is the toughest.
Aciniform silk: For preserving fresh prey.
Minor-ampullate silk: This type is used by spiders for creating temporary support while they are spinning a web. Etc.

Yuri [45]

Answer:

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Explanation:

We are looking for a parent cell that gives rise to daughter cells with identical genetic information.

In simpler words, we are looking for something that makes 'clones' of itself.

In this statement (second option), the parent and daughters are all feline skeletal muscle cells.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Other incorrect choices: (All having to do with reproduction).

A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.

This situation has two parents, each with a different trait. The child takes one of the parent's trait. The parents did not make a 'clone' of themselves.

A human sperm fuses with a human egg cell, resulting in the development of a new human.

The parents don't make 'clones' of themselves. The sperm did not make more sperm. The egg did not make more egg cells.

A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.

The offspring plant only took the trait from one of it's parents. Also, whole plants are not individual cells.
