Answer:

<em>Kinesis</em>

Explanation:

Innate behaviours are behaviours that occur naturally in animals in response to external stimuli. These reflexes, taxis and kinesis.

Reflex actions are actions that occur involuntarily in response to external stimuli.

Kinesis is a non directional movement of organisms in response to external stimuli.

Taxis is a directional movement of organisms in response to external stimuli. It could be towards the stimuli or away from it.

<em>In this case, the roly-poly bugs move aound in no direction until they find a suitable moist spot. This is certainly a kinesis.</em>

It is known as symbiosis. Symbiosis is a connection between at least two creatures that live firmly together. Advantageous interaction can be required, which implies that either of the symbionts completely relies upon each other for survival, or facultative when they can for the most part live freely.

For fertilization to occur in humans, only one sperm is needed to weaken the barrier that surrounds the egg.
photoshop1234 [79]

Answer:

False

Explanation:

Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg.  They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg.

The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present.

Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it.

postnew [5]

Answer:

There should be 10% thymine

Explanation:

DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.

According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.

If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.

10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%
