Excitation-contraction coupling refers to the series of events that begins with the excitation of the sarcolemma in response to stimulation by a neurotransmitter, and results in the release of calcium ions from the sarcoplasmic reticulum.
Hence, option D is the 1st process that starts the excitation-contraction coupling.
A. Antarctic blue whale
B. Herbivores
C. Inland Taipan
D. “The scientific name Asteroidea was given to starfish by the French zoologist de Blainville in 1830. It is derived from the Greek aster, ἀστήρ (a star) and the Greek eidos, εἶδος (form, likeness, appearance). The class Asteroidea belongs to the phylum Echinodermata.”
E. “First, primates have larger eyes than many other mammals of comparable body size (Ross & Kirk, 2007). Having large eyes ensures that a large image is formed on the retina (Walls, 1942; Land & Nilsson, 2002). This large retinal image may then be sampled by many photoreceptors, improving visual resolution. Primates have flexible shoulder joints and and strong clavicles or collar bones that help them use their arms more effectively than other species of animals. Most primate can hold their bodies erect and some species, including humans, can walk on two legs instead of four.”
Ye because ur looking at a grossly bear very scary and also it can bite u so hard that ur brain is gonna splatter everywhere into tiny bits of chunks
Carrying capacity is the maximum amount of organisms a certain ecosystem can sustain with the resources available in a given ecosystem.
Factors that could either increase or decrease the K, carry capacity, would be: drastic weather causing depletion of resources, decreases in competition, etc.
