Answer:
The correct answer will be option-They have about the same endurance as skeletal muscle fibers.
Explanation:
Cardiac muscle is one of the three types of muscle which is present in the Heart of the organism.
The muscle fibres of the cardiac muscle possess a high amount of myoglobin- an Oxygen carrying molecule which can store the oxygen for some time.
The cardiac muscles have to pump blood in the body, for which they require a high amount of ATP, so they possess larger mitochondria.
The studies have shown that the cardiac muscles store glycogen carbohydrate which is used during the relaxation phase in stress conditions.
Since the cardiac muscles do not have the same endurance as the skeletal muscles which with physical exercise can be increased therefore the selected option is the correct answer.

Answer:
The correct answer is - XTXt
Explanation:
In the question, it is given that in cats the coat color is an X-linked trait that shows incomplete dominance if present in heterozygous condition.
The allele for yellow allele = XT (it is dominant allele)
The allele for black coat = Xt (it is recessive allele)
The amle cat can not show the heterozygous condition or tortoise coat as they have only one X chromosome so they will be either yellow coat cats or black coat cats.
In female cats the tortoise coat will show when the both allele present together: XTXt due to their incomplete dominance.
The rough endoplasmic reticulum. The rough ER is responsible for protein synthesis, so they should be abundant in cells that secrete a lot of digestive proteins.
Answer:
Plants can be used to make materials.
Explanation:
Plants are important living organisms and they can be used in many ways. Some plants can be used as foods, some plants are used as raw materials for making medicines and other herbal products. Plants, such as cotton are used to make clothing materials and dead and decaying plants serves as fertilizer that add nutrients to the soil.
