Answer:
osculum.
Explanation:
The large central opening in the parazoan body is called the osculum. In short, the protozoan body usually has bag-like structures. The inner cavity is called the atrium. In the upper part of the atrium there is an opening, the osculum, which serves to eliminate water with substances unnecessary for protozoan nutrition and with debris resulting from cellular activity.
Let’s simplify step by step
-6x-4x+2
=-6x+-4x+2
Combine Like Terms:
=-6x+-4x+4
=(-6x+-4x)+(2)
=-10x+2=Answer
Factor way answer for factor would be 2(-5x+1)
Hope this helps pls give me BRAINLIEST
A direct observation usually refers to observing a behavior and knowing exactly what is happening. For example, if I see a pigeon peck at some bread, I have observed it pecking. With direct observation, I cannot assume it is eating, that it is hungry, that it has any intention whatsoever. All I know is that it pecks.
Answer:
A,C,F,E,D,B
Explanation:
The is the sequence of action potential transmission at at the neuromuscular junction. Generally the arrival of action potential from the presynptic neuron caused influx of ca+ which causes migration and the release of the the acetycholine to the synaptic cleft.
The acetycholine binds with the receptors on the saccolemma to causes opening of Na+ , its influx to causes depolarizarion of the sacolemma. The depolarization of the latter spreads along the transverse tubules, This depolarization causes increases in the permeability of the sacorplasmic reticulum, with opening of ca+ channels and diffusion of Ca+ out of the S. reticulum.
The Ca+ binds to troponin,and tropomyosin exposed the myosin-binding sites on actin filament . The myosin head forms the cross bridges with the filament, and therefore the sacomere shortens leading causing muscle contraction.
