The type of muscle found at the heart is the cardiac muscle tissue. This tissue has the phyical striped characteristic of a skeletal muscle tissue and works like a involuntary muscle because it works without our control
This type of tissue is packed wirh mitochondria which provides it with alot of energy. This is very crucial becaise the heart has to constantly beat

Answer:
Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.
Explanation:
Since the four proteins used p16,  p18,  p21, and  p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.
Hope that answers the question, have a great day!
 
        
             
        
        
        
<span>In
the process of polymerization, a chain of similar smaller molecules
called monomer join together to create very large molecules called
polymer. Through this chemical reaction, water is created as a
by-product. In contrast to hydrolysis or breaking down of polymers, a 
water molecule is used to break the covalent bond that hold the
components of a polymer.</span>
        
             
        
        
        
Baecaise dolphins are aquatic animals, Logan will want to make sure the dolphin's skin stays moist by keeping it in water while transporting
<h3>What are aquatic animals?</h3>
Aquatic animals are animals that live in water.
Aquatic animals may live in either fresh water or marine habitats.
Aquatic animals need to be in water environment in order to keep living.
Dolphins are aquatic animals that live in marine habitats. 
They have the ability to get their oxygen from water.
Therefore, Logan will want to make sure the dolphin's skin stays moist by keeping it in water while transporting
