What is the temperature and name of the surface ocean current that affects the climate of location E (see map above)?
(1) warm Alaska Current
(2) warm Gulf Stream Current
(3) cool Peru Current
(4) cool California Current
Answer:
it is 4 the cool California Current
Explanation:
The temperature and name of the surface ocean current which affects the climate of the location E is the Cool California Current. Thus, the correct option is 4.
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.
Therefore, the correct option is 4.

Stimulus:
Tropism:
Response:
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.
Positive tropism ⇒ the plant moves forward to the stimuli sourceNegative tropism ⇒ The plant moves away from the stimuli source

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.
