algol13

Answer:

The preferable option will be - A.

A. similar environments and specific traits increased their chances of survival.

Explanation:

The shark and dolphins have similar body shape and fins. But shark is a fish and dolphin is a mammal.

Both of them are exposed to similar kind of environments. Both of them possess a specific kind of alternative characters and traits.

Surface currents in the Northern Hemisphere rotate in a _______ direction. In the Southern Hemisphere, the surface currents rota

trapecia [35]

Explanation:

Surface currents in the Northern Hemisphere rotate in a Clockwise direction whereas in the Southern Hemisphere, the surface currents rotate in a anticlockwise direction. This happens because of the Coriolis effect, because of this Coriolis effect surface currents are shifted to angle of 45°. Therefore, it deflects the current towards right in northern hemisphere and towards left in southern hemisphere.

Plant hormones act by directly affecting the activities of _____. genes enzymes signal transduction pathways genes and enzymes m

Readme [11.4K]

Answer:

Signal transduction pathways

Explanation:

Plant hormones act by directly affecting the activities of signal transduction pathways.

Signal transduction pathways are involved in the transfer of signals from outside of the cell to the inside of the cell for the regulation of various cellular activities. For this, the extracellular signalling molecules bind to the receptors that are located on the cell membrane. After their binding due to some change in the receptor molecule, a signal is triggered in to the cell and thus information from outside of the cell is transferred to the inside of the cell through these transduction pathways.

Plant hormones affect these pathways and as a result membranes, enzymes, and genes are also influenced by the plant hormones.

Vesna [10]

The correct answer is:

_________________________________________________

→ " commensalism" .

_________________________________________________

<u>Note</u>: "Commensalism" refers to a symbiotic relationship {"symbiosis"} between two (2) organisms — in which one organism benefits and the other organism is neither helped nor harmed.

{ i.e. " +, 0 " ; that is: "plus" sign for "one organism benefits" ;

"zero" sign for "neutral" ;

(in that the other organism is neither helped nor harmed.}.

_________________________________________________

In the example given in the question, the two (2) organisms are:

1) the barnacles; and: 2) the shellfish.

The barnacles benefits by given a place to attach for the purpose of transportation (by using the shellfish to "cling to"}.

The shellfish are neither helped (benefitted in anyways from the attachment from the barnacles— nor are the shellfish harmed in any way.
