Answer:

Explanation:

For number 4, it tells you that purple body color is dominant to blue.

When an allele is dominant over another allele (alleles are different forms of genes, represented using letters) that means only one dominant allele needs to be present to express the dominant phenotype (phenotype is the physical appearance determined by genotype). Since purple is dominant, we use a capital "P" to represent it. Since blue is not dominant, it is called recessive, so we use a lower-case "p" to represent it.

The first genotype they give you, it is "PP", and since at least one big P is there, the phenotype is purple.

The second genotype they give you is "Pp", and since there is at least one capital P, the phenotype is also purple. It does not matter that the second allele is a lower-case, because as long as there is a capital P present, it will masks the presence of the lower-case (recessive) allele.

The third genotype is "pp", both are lower-case, so there is not dominant allele to mask the recessive ones. So, the phenotype is blue. The recessive phenotype will only be phenotypically present if the genotype is homozygous recessive.

Homozygous - having both of the same alleles (PP or pp)

In which PP is known as homozygous dominant, because it is made from the dominant allele. And pp is known as homozygous recessive, because it is made from the recessive allele.

Heterozygous - having one dominant and one recessive allele (Pp)

Note: It does that really matter what letter you use, the importance is whether it is a capital or not because that tells you if it is dominant or recessive.

The same for square shape. It says that square is dominant over round, so a capital letter is used to represent square (S), and a lower-case to represent round (s).

Therefore, the phenotype would be:

Square, Square, round, respectively.

Number 5 is asking you to go from the phenotype (physical look) to the genotype.

Tall head is (T) and dominant to short (t).

Tall = could be PP or Pp (homozygous dominant or heterozygous). It could be both since in both genotypes at least one dominant allele is present, so it will result in a dominant phenotype.

Short = tt. It is "tt" because it is recessive, and the only way to physically show the recessive phenotype is to have a homozygous recessive genotype.

Green is dominant over blue, so again.

Green body - the genotypes could be GG or Gg. At long as there is one capital (dominant) allele.

Yellow body - gg (it is recessive, so it cannot have a capital "G", or that would masks the recessive g).

Hope this helps.

iris [78.8K]

Answer:

Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system changes to relieve the stress.

Explanation:

This principle shows that when we change a system in equilibrium, it will seek to acquire a new state that nullifies this disturbance. Thus, there is a displacement of equilibrium, that is, a search for a new equilibrium situation, favoring one of the senses of the reaction. If it favors the direct reaction, with formation of more product, we say that the equilibrium has shifted to the right. However, it is said that it shifted to the left if the reverse reaction was favored, with formation of reagents.

Keith_Richards [23]

Answer:

lost-update program

Explanation:

Based on the information provided within the question it can be said that this is an example of the database problem known as lost-update program. This term refers to when more than one individual is attempting to update a database entry within the same column and same row, at the same time. This causes the first entry that was saved by the system to be completely overwritten and lost. Such as what happened to Irene's report since it was saved first and then overwritten by Charle's report.

Describe an experiment to investigate the effect of training on subjects ability to run faster without respire get anaerobically
Zinaida [17]
A runner HAS to use the anaerobic respiration process,first we need to know the difference between anaerobic respiration and aeorobic respiration 

<span>Anaerobic respiration is done by burning glucose directly without the presence of oxygen giving out lactic acid and energy </span>
<span>Aerobic respiration is done by burning glucose and oxygen giving out water + engergy + Co2 </span>

<span>1.) Take a stop-watch </span>
<span>2.) Take TWO or more runners </span>
<span>3.) Unlike Olympic race match ask ONE of the runners to run their fastes and the others to GRADUALLY speed up </span>
<span>4.) make the runners breath hard for air </span>
<span>5.) after finish line </span>
<span>6.) do a test of Lactic through urin test or use Lactometer (don't ask me how to use it 'cause I don't know lol) </span>
<span>7.) check the concerntration </span>
<span>8.) whoever has the LOWEST concerntration,take that runner time for running and meter to find speed you'll be able to spot out who has used aerobic respiration during the race</span>

What geological theory explains how llamas and camels, close relatives, might be found on different sides of the world?
Pavlova-9 [17]
The answer is continental drift. 
Continental drift is the geological theory that explains how continents move through Earth's surface. All continents were once connected as one supercontinent Pangea. On that supercontinent, many related species, such as llamas and camels, lived together on one location. But after continents spread apart, related species were separated on different continents and adapted to different conditions
