I would say the answer is c or d
Answer: Genetic variability is beneficial for the survival and adaptation. But a flaw in DNA Replication Control or check may leads to the death of cell or may contribute in the disease or cancer.
Explanation:
Almost every species comes with the diversified collection of genes (genome). And some of the diversity comes from the spontaneous mutation but it occurs on a very low frequency. The genes either express constitutively or occasionally for an important task like genes responsible in the generation of ATP by glycolysis, tricarboxylic acid cycle, electron transport chain etc. While some of the genes are inducible that is only activated in a response to an external stimuli. Genetic variations in inducible genes might account for the adaptability or negligible change in a species genetic expression but genetic variation in constitutive or house keeping genes leads to cancer cell formation or even cell death. like mutation occur in p53 genes dysregulate the cell cycle or mutation occur in DNA polymerase enzyme that is responsible for the incorporation of NTPs (nucleotide tri-phosphates) according to wobble base pairing rule in order to make a complementary new strand from the old or parent strand, will eventually leads to cause mutations ultimately results in cell death or cancerous cell formation.
What’s the smallest muscle in the human body?
The stapedius, in your middle ear, measures about 1mm in size (or
1/26 of an inch). Connected to the stapes bone, it contracts to pull
back the stapes and help protect your inner ear from loud noises. The
stapedius also contracts to keep your own voice from sounding too loud
in your head.
What’s the smallest bone in the human body?
Conveniently, that would be the stapes. It is one of three tiny bones
in the middle ear that convey sound from the outer ear to the inner
ear. Collectively called the ossicles, these bones are individually
known as the malleus, incus, and stapes. Those are Latin words for the
shapes the bones resemble: a hammer, anvil, and stirrup.
What’s the smallest organ in the human body?
You’ll find the pineal gland near the center of the brain, in a
groove between the hemispheres. It’s not an organ like those in the
abdominal cavity. It’s the human body’s smallest endocrine gland, and it
produces melatonin, a hormone (derived from serotonin) that affects how
we sleep, wake up, and react to seasonal changes. It’s called pineal
because it’s shaped like a little pinecone.
What’s the smallest blood vessel in the human body?
<span>Capillaries, the smallest, thinnest-walled blood vessels in the body,
connect veins and arteries. They can be as small as 5-10 micrometers
wide — or 50 times thinner than a baby’s hair. Each of us contains about
10 billion of them, with the average adult body containing about 25,000
miles of capillaries.</span>

Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.
