Science can only explain logical questions and provide answers to things that only can be scientifically proven. Things that are asked in society like religion can not be further explained. The reason why we have religion is because we have always believed in something in history. Either is was made up or concocted out of no where, humans have always believed in something. But what science can't explain is the miracles and things that have happened. Like Jesus, they can't prove that he performed miracles or was the Son of God. They can't prove he and his body ascended into heaven. Science can't explain that God is real. Yet the only thing you can do is believe in it, and trust the Bible accounts are accurately true.
In cardiac muscle
a. an action potential spreads throughout the Z discs.
b. intercalated discs connect the muscle fibers together.
c. calcium enters the cell from storage chambers called intercalated discs.
d. potassium is released from the sarcoplasmic reticulum
Answer:
b. intercalated discs connect the muscle fibers together.
Explanation:
Intercalated discs are components of the muscles found in the heart(cardiac muscles).
Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.
Intercalated discs are made of up desmosomes and gap junctions.
Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
Answer:
Birds will eat different foods based on their environments, and other physical factors.
Explanation:
Birds will eat different things depending on what is the most available in the environment. If there is a lot of fruit, they'll prefer that over bugs and worms. If there is a lot of bugs, they probably will go for those instead of the one or two pieces of fruit.
Physical factors weigh in as well. Birds' beaks can change over many generations to better suit the consumption of certain types of food. HUmmingbirds have long thin beaks so they can get nectar inside of flowers, and they might have a hard time eating a large fruit. Similiarly, other kinds of birds are better adapted to eating certain kinds of food too.
