Study the cladogram. Which two organisms have dry skin? gorilla and shark shark and lizard lizard and tiger tiger and lamprey.
Answer:
It's C.
Explanation:
I chose B but I got it wrong. Since lizards obviously have dry skin, the other option with lizards is C. And you can also see in the cladogram that above "dry skin" is lizards and tigers.
So it's C.
The relationship between the two organisms is represented by a cladogram. Here, dry skin is seen in lizard and tiger. Thus, option c is correct.
What is a cladogram?Cladogram is based on the evolutionary relationship between the organisms and how closely they are related to each other. It is expressed in the form of branching diagram.
In cladograms, the morphological features are included. However, advanced cladograms can be constructed using DNA or RNA sequencing.
Cladograms are useful tools for studying evolution as they are represented through simple diagram. The advantage of using cladogram is that it includes only the pure characters. No derived characters are taken into account.
Thus, cladograms are important in determining the evolutionary relations amongst the taxonomic groups.

Why is it difficult to male level 4 organs in a lab?
Answer:
By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.

Assuming that the population was in hardy-weinberg equilibrium for the g locus, what percentage of moths in the natural population was white in 1962 ?.
The percentage of moths in the natural population that was white in 1962 is : 4%
What is Hardy-weinberg equilibrium ?Hardy-weinberg equilibrium states that the sum total of all the genes of an individual in a population is constant when the disturbing factors such as genetic drift does not occur
p² + q² + 2pq = 1
Determine the percentage of moths in 1962Applying the equation below
p² + q² + 2pq = 1
p = frequency of dominant allele
q = frequency of recessive allele
q² = frequency of h0m0zygous recessive genotype
p² = frequency of h0m0zygous dominant genotype
From the graph
Frequency of G allele ( i.e p ) = 0.8
percentage of white moths = q²
Note : p + q = 1 ---- ( 1 )
Insert value into equation ( 1 )
0.8 + q = 1
therefore ; q = 0.2
Hence the percentage of white moths = ( 0.2 )² = 0.04
= 4%
Hence we can conclude that The percentage of moths in the natural population that was white in 1962 is : 4%

Hydrotropism is the root motion toward the water source. In the example, Stimulus: Water. Tropism: Hydrotropism. Response: Roots growth toward the water leak.
What is Tropism?In botanic tropism refers to the biological response of the plant during its development to an external stimulus. These responses are usually noticed as plant motion, forward to or away from the stimulus source.
Stimuli can be good or bad for the plant, and depending on this, the plant will try to get closer or farther. According to this, Tropism can be either positive or negative.

What is the Cool California Current?The California Current is called as an eastern boundary current. The strong current systems which flow along the east side or the boundary of all of the Earth's major ocean basins. These tend to move the water towards the equator, and they are prone to strong upwellings.
The temperature and salinity of the waters of the California current vary with the seasonal variations in the upwelling, insolation, and flow of the water. The maximum range in the temperature and salinity from its northern to its southern end are 48° to 79° F or 9° to 26° C and 32.5 to 34.5 parts per thousand, respectively.
