A.true
It's because all arteries carry oxygenated blood from heart to the tissue,except for arteries pulmonary which carry deoxygenated
Blood.
All veins carry deoxygenated blood from the tissues to the heart except for pulmonary veins which carry oxygenated blood to the heart.
1) Bacteriophage injects its DNA into the host cell
2) The DNA circularises
3) Viral gene activates the host cell's DNA synthetic machinery
4) Rapid reproduction of viral DNA occurs
5) Host makes viral capsomeres, allowing viral assembly to take place
6) Due to the large volume of new bacteriophages inside the host cell, the cell splits (cell lysis), releasing the new bacteriophages
Answer:
The answers are:
- Type 2 (fast twitch) muscle fibers - type A: b. muscle fibers that help with a long sprint or carry a heavy object a short distance
- muscular strength: d. the muscle's capacity to exert force against resistance
- Type 1 (slow twitch) muscle fibers: a. muscle fibers responsible for endurance
- Muscle endurance: c. refers to the ability to perform a specific muscular action for a prolonged amount of time.
- Type 2 (fast twitch) muscle fibers - type B: e. muscle fibers used in short explosive movements such as jumping or lifting a very heavy weight one or two times.
Explanation:
Types of Skeletal Muscles:
Skeletal muscle are divided into two types:
- Slow Twitch (Type 1)
- Fast Twitch (Type 2)
- Slow twitch muscles are the first ones to contract at times of exercise of strenuous physical activity. A compared to fast twitch muscle fibers, they contract slowly but can sustain contraction for a long time.
- Fast twitch muscle fibers are divided into two subtypes: Type 2A and Type 2B.
- Type 2A muscle fibers produce a high amount of force but they fatigue rapidly.
- Type 2B muscle fibers, fire last, produce the most amount of force but wear out very rapidly.
Muscle Characteristics:
- Muscle endurance is the muscle's ability to contract with force against a resistance for a prolonged time period.
- Muscle strength is a measure of the amount of force a muscle can produce against resistance.
The snake population will decrease. If all of the mice in an area die out, some snakes — which feed primarily on mice and other small animals — will starve unless they are able to find another food source.
