Biology
1 answer:
PilotLPTM [1.2K]3 years ago
5 0
When an acetate fiber is cut and is seen under a microscope, the cross section is crenulated shaped. Crenulated shaped cross section is a resultant effect when the external part of the cellular solution solidifies first than the interior of the acetate fiber when taken out rapidly out the acid bath.

Which end of actin filaments within sarcomeres is associated with (attached to) Z discs?a) The plus end for all actin filamentsb
aliina [53]

Answer:

The plus end for all actin filaments.(Ans. A)

Explanation:

All three types of muscles (cardiac, smooth, and skeletal) utilize actin filaments to generate force which leads to cell contraction. Actin filaments is organized into sarcomeres which function as the fundamental unit of contraction.

Sarcomeres are approx 2.4 micro meter in length, and they are bounded at both end with the help of Z-disks. Plus end of the Z-disks are oriented with actin filaments and their minus ends to the direction of center of the sarcomeres. Z-disk consist an actin capping protein, which is known as cap-Z. Cap-Z helps to bind plus end of the actin filaments.

The diagram shows the thermohaline circulation, also know as the ocean's conveyor belt.
DanielleElmas [232]

Answer:

The statement that is true about red currents in the thermohaline circulation is that  water in the red currents contain less salt (option A).

Explanation:

Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.

On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:

  • <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
  • <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>

The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.
