Describe how the life cycles of the grunion and the horseshoe crab are timed to the rhythm of the tides?

Answers

Answer:

Grunion (Leuresthes tenuis): life begins at high tide. During summer and spring, thousands of these fish swim up onto sandy beaches (carried in by high tide). This is called a grunion run, and it occurs ta night during the new moon and full moon when the tide is highest. The females wiggle into the sand and lay thousands of eggs as the males deposit sperm around them. Afterward, they are swept back into the sea. The spawning is timed so exactly that it occurs only on the second, third, and fourth days that follow a new or full moon. After the grunion eggs are fertilized, they incubate for two weeks until the next new or full moon occurs.

Horseshoe Crab (Limulus polyphemus): during late May and early June, vast numbers of horseshoe crabs come together in shallow bays, marshes, and inlets along the Atlantic and Gulf coasts, waiting to come up on the beaches to spawn. The signal to begin is provided by the moon. During the new and full moons, when tide is highest, the crabs come ashore. The female produces a cluster of tiny eggs on her abdomen, and the eggs are fertilized by the male's sperm, and then deposited out in the sand by the female. The next two weeks, the eggs incubate until they hatch during the next full or new moon. When the high water reaches the eggs, they hatch and go out into the ocean.

What kind of information can scientist get from soft body parts that they cannot get from hard body parts?

Answers

Answer:

Function and working mechanism.

Explanation:

Information such as function and working mechanism etc can a scientist get from soft body parts that they cannot get from hard body parts because these soft body parts perform their work continuously and we can study it through a number of ways and methods. The working mechanisms of hard body parts can't be study because they are not visible to any instrument and occurs inside their structure so that's why function and working mechanism are the information given by the soft body parts.

When working with eye shadow, a color is generally a medium shade that is close to the client skin tone

Answers

Answer:

When working with eye shadow, a base color is generally a medium shade that is close to the client skin tone

Explanation:

A color base is used to generate uniformity and smoothness on a surface that will be painted. This technique is used both in artistic paintings and in make-up, as the question above shows, showing that a color base is used on the eyes before the eye shadow is applied. This is because the color base, by standardizing the color of the eyelid, allows the colors of the eye shadow to stand out and appear more pigmented, in addition to allowing the eye shadow to last longer in the customer's eyes.

Write the CODON that corresponds with each amino acid. There may be more than one. The full names are written, but the codon chart only shows the first three letters. proline ______________________ glycine ______________________ valine ______________________ phenylalanine ______________________ histidine ______________________ arginine _________________

Answers

Answer:

In protein synthesis, different mRNA codons produce different amino acids by the translation process with the help of ribosomes and tRNA. These mRNA sequences are read in sets of three which are termed as triplet codons. Specific amino acids are produced by different codons, however, more than one codons code for one amino acid. The given amino acids correspond with the following codons:

Proline: it corresponds with four codons

1. CCT  

2. CCC  

3. CCA  

4. CCG

Glycine: it corresponds with four codons

What is the N sample?

The N sample refers to the number of objects and/or persons tested during an experimental procedure.

The N sample is fundamental for eliminating the source of variation that may lead to errors.

These errors are a consequence of faulty testing of a suitable number (N) sample.

In conclusion, the statement 'she did not collect data from enough people' is a source of error in an experiment (Option A).
