Answer:

There are only four parts of skill related fitness in the options; they are:

Speed

Agility

Balance

Coordination

Explanation:

Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.

However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:

- Speed: This refers to the ability to run a distance in a short time frame.

- Agility: This is the ability to move easily and quickly in different directions

- Balance: The ability to maintain an upright body position during training or physical activity

- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.

Note that, Aerobic Endurance and Muscular strength are health-related components of fitness

Final answer:

The five components of skill-related fitness are Speed, Coordination, Agility, Balance, and Muscular Strength. Each plays a different role in physical activities and sports.

Explanation:

The five parts of skill-related fitness are; Speed, Coordination, Agility, Balance, and Muscular Strength.

• Speed: It is the ability to move quickly. It is crucial in many sports such as sprinting, swimming, and soccer.
• Coordination: This refers to the ability to use different parts of the body smoothly and efficiently together. For example, dribbling a basketball while running.
• Agility: It is the ability to change the direction of the body quickly and effectively while maintaining control. Gymnasts, soccer players, and basketball players display good agility.
• Balance: It involves maintaining body equilibrium to prevent falling. It's used in activities like yoga, gymnastics and ice-skating.
• Muscular Strength: Not to be confused with muscular endurance, muscular strength is the amount of force that a muscle can produce in a single effort. It’s used in activities such as weightlifting and shot put.

The eustachian tube help a frog survive they are used to equalize pressure within the internal ear whilst the frog is swimming. A slender tube that connects the tympanic hollow space with the nasal part of the pharynx and serves to equalize air strain on both aspects of the eardrum. The Eustachian tube helps the frog to bring in sound and to listen. The Eustachian tube of a frog equalizes the strain of the internal ear by using beginning and final, which aids with sound and listening. They help to stabilize the frog. The Eustachian tubes additionally cause the eardrums. Or as a substitute so it's simpler to consider the most important function of the frog's Eustachian tube is that it became especially used for equalizing stress inside the internal ear while the frog is swimming. It equalizes the pressure of the frog's inner ear even as it is swimming. Used to equalize strain inside the internal ear while the frog is swimming. It gives blood to Equalize stress between the inside and outside ear.

How do you clean block the Eustachian tube?

Valsalva maneuver, Pinch your nostrils closed with your arms. try to preserve your cheeks neutral or pulled in as opposed to puffing out. next, blow air gently thru your nostrils. This generates stress inside the back of the nostril, which may additionally assist open the eustachian tube.

A commonplace direction of remedy for Eustachian tube dysfunction is using decongestants or antihistamines. In some instances, this treatment may additionally make the situation worse. If decongestants or antihistamines no longer provide a remedy, touch your medical doctor. you could want to peer an ear, nostril, and throat specialist for treatment.

Hypersensitive reactions and infections (like the common bloodless and the flu) are the maximum common reasons for eustachian tube dysfunction. Those conditions can cause infection and mucus buildup, leading to blockage. GERD, or continual acid reflux disorder, also can be purpose ETD.

They are used to equalize pressure in the inner ear while the frog is swimming. A slender tube that connects the tympanic cavity with the nasal part of the pharynx and serves to equalize air pressure on either side of the eardrum. The Eustachian tube helps the frog to bring in sound and to hear. The Eustachian tube of a frog equalizes the pressure of the inner ear by opening and closing, which aids with sound and hearing. They help to balance the frog. The Eustachian tubes also lead to the eardrums. Or.... instead so its simpler to remember the most important function of the frogs Eustachian tube is that...It was mainly used for equalizing pressure in the inner ear while the frog is swimming.It equalizes the pressure of the frog's inner ear while it's swimming.Used to equalize pressure in the inner ear while the frog is swimming.it gives blood Equalize pressure between inside and outside ear. We as individuals can equalize many things but i tell u this daythe frog has no tube or ear.

'Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands.' best describes the role of helicase and DNA polymerase in DNA replication. The correct option is d.

Helicase is essential for DNA replication because it "unzips" the double-stranded DNA molecule. In order to separate the two strands and create a replication fork this process involves severing hydrogen bonds between the base pairs. On the other hand, DNA polymerase is charged with the vital task of creating new DNA strands.

It does this by incorporating complementary nucleotides into the template strands already present. This maintains genetic fidelity by ensuring that the newly formed strands mirror the original ones. The precise duplication of genetic information which is necessary for cell division and inheritance, depends on the interaction between the unwinding action of the helicase and the strand-building activity of DNA polymerase.

Answer:

It would look like this:

Explanation:

DNA is the buiding block of life

No one can live without it

Along side its sister, rNA that harlet

(idk if you need to include the replication part but here you go)

Replicating with any old DNA sequence

Everyone agrees however, that

People need her for living

Little old rNA sticks around another day

Initiating protien synthesis with DNA after DNA

Carrying information and storing code

A virus may invade a cell

To infect it with its kin

In the end it may prevail

Or perhaps be fended off and killed

No matter what, rna will be there, doing its thang.
