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.

In your own words Describe how autotrophs and heterotrophs obtain energy. please this answer must be at least 150 words any one
blsea [12.9K]

The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.

Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers.  They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.

Some are photo-hetrotrophs,  who use light as energy but cannot use carbon  dioxide as the carbon source since they cannot fix the carbon like autotrophs.
