<h2>Region between 2 and 3</h2>

Explanation:

Muscles consists of two protein filaments:a thick filament which is made up of protein myosin whereas a thin filament is made up of protein actin

During contraction,thin filaments slide past the thick filament resulting in shortening of sarcomere
Myosin thick filaments grab on to the actin filaments by forming cross bridges
The thick filaments pull the thin filaments past them making the sarcomere shorter
The region between points 2 and 3 includes the area of overlap between thin and thick filaments

What current will an ammeter register if 960C of charge flow through it in 2 minutes?

postnew [5]

Answer:

Explanation:

I= Q/t, where

I= current (A)

Q= charge (C)

t= time (s)

First convert the time from minutes to seconds.

1 minute= 60 seconds

2 minutes= 2×60= 120 seconds

Using the formula,

I= 960÷120

I= 8A

Identify the structural class of each gland described here 1. flask shaped gland unbranched ducts slender, straight gland unbran

posledela

1. flask-shaped gland unbranched ducts=SIMPLE ALVEOLAR GLAND

2. slender, straight gland unbranched ducts = SIMPLE TUBULAR GLAND

3. combination of gland shapes = TUBULAR ALVEOLAR

4.branched ducts=COMPOUND GLAND (salivary glands)

All of them are the exocrine glands (their product is secreted on the epithelial surface).
