Which process involves wind moving loose sediment?

(c) Based on the data in Table 1, describe why the dominant alleles for body color and wing shape are the alleles that produce a

Brrunno [24]

Answer:

Check the explanation

Explanation:

Consider the below table of F2 data of phenotypic flies: we can reconstruct the table as seen in the second attached image below:

From the above observations it is clear the Gray body long wings and Ebony body vestigial wings are the parental combinations and that the Gray body vestigial wings and Ebony body long wings are the recombinants.

Also the ratio indicates that Gray body is dominant over ebony body and that long wings is dominant over vestigial wings.

here the genes for the two characters have shown independent assortment which means that the genes are unlinked if located on the same chromosome or are located on different chromosomes.

Now F1 hybrid= GgLl (G for Grey and L for Long)

Cross between F1 hybrid and true breeding Gray vestigial (GGll)

GgLl x GG ll

Gametes-----------> GL Gl gL gl Gl

GL Gl gL gl

Gl GGLl GGll GgLl Ggll

(Gray long) (Gray vestigial) (gray Long) (Gray vestigial)

Therefore the probability of getting the flies with gray body vestigial wings= 2/4= 50%

b) The reason why the students obtained the above given F2 results involving a cross between true breeding Gray body and long wings with true breeding Ebony body and vestigial wings is that the genes for the two charcters asssort independently in F2 generation and that the genes are not linked as:

Parents------------------> GGLL x ggll

Gametes -----------------> GL gl

F1---------------------> GgLl (Gray long but in heterozous condition)

Now GgLl x GgLl

Gametes GL Gl gL gl GL Gl gL gl

Here gametes assorted independently and hence in F2 generation we got the above results (U can show the results in the form of punnett square.

Why do lipophilic hormones require carrier proteins while being transported in the blood?

valina [46]

Lipophilic hormones, intuitive as the name suggests, tend to dissolve well in lipids/fats than they do in water. Therefore lipophilic hormone does not dissolve well in blood plasma which would affect their diffusion. The carrier proteins are mainly the serum albumins.

one of the most important rain forest predators, attacking a wide range of different primates, is the monkey-eating eagle. we know this because all forest primates have an identical alarm call that means, essentially, "Eagle!"

<h3>What are primates?</h3>

Primates are those forest animals that has highly developed brain and backbone.

Some of them are predators while others are source of food for predators known as preys.

Example of such predators are the monkey eating eagles which are capable of hunting monkeys as their preys.

List four methods that can be used to separate mixturea and give an example of each method

Evgesh-ka [11]

Distillation, Filtration, evaporation, and Chromatography

The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air.

Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points..

Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates

Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components
