Answer:
The fastest land animal is the cheetah coming in at 80 miles per hour being the average top speed.
Explanation:
Answer:
Cheetahs are the world's fastest land animal, capable of reaching speeds of up to 70 mph.
Explanation:
At 60–90cm, the muscular tail is half the head and body length. It acts like a counterbalance, aiding high speed manoeuvring. The exceptionally long vertebral column has amazing flexibility, and as it flexes and straightens this boosts stride length.Compared with other cats, all of the leg bones are stretched. The tibia and fibula are also fused to give more stability at speed, though this interferes with climbing.

Explain. How mitotic cell division results in more cells that allow growth of the organism, can differentiate to create different cell types, and replace dead cells to maintain a complex organism.
Answer:
The mitotic cell division results in more cells that allow growth of the organism because of mitosis. Mitosis is when a single cell divides into two identical daughter cells. The major purpose of mitosis is for growth and to replace worn out cells.

The soil which is made up of 25% sand, 25% silt, and 50% clay is known as loamy soil.
What are the characteristics of soil?The characteristics of soil are as follows:
Soil is typically composed of organic matter and small inorganic matter.It is significantly composed of minute rock fragments and is the roughest in texture. It possesses a broad characteristic of texture, structure, porosity, chemistry, and color. It generally consists of air, water, and moisture.According to the context of this question, the loamy soil significantly consists of 25% sand, 25% silt, and 50% clay. This is because it is the only soil that possesses a mixture of sand, clay, and silt.
Apart from this, it also consists of 50% pore spaces and water. The presence of an equal amount of soil particles of various sizes imparts enough pores to loamy soil to facilitate water drainage.
Therefore, the soil which is made up of 25% sand, 25% silt, and 50% clay is known as loamy soil.

What occurs during the latent period of these isometric contractions.
Answer:
The latent period refers to the period of time, in which no force is generated, that elapses between the generation of an action potential and the beginning of muscle contraction. The contraction phase begins at the end of the latent period and ends at the peak of muscle tension.
Explanation:
:)
During the latent period of isometric contractions, there is no visible change in muscle length. It is the time period between the initiation of a stimulus and the actual start of muscle contraction.
Here is a step-by-step explanation of what occurs during the latent period:
1. The stimulus is received by the muscle fiber, either from a motor neuron or an electrical impulse.
2. The stimulus triggers the release of calcium ions from the sarcoplasmic reticulum.
3. Calcium ions bind to troponin, causing a conformational change in the troponin-tropomyosin complex.
4. This conformational change exposes the binding sites on actin for myosin heads.
5. ATP is hydrolyzed by myosin, providing energy for the myosin heads to bind to actin.
6. Cross-bridge formation occurs, where myosin heads attach to actin filaments.
7. However, during the latent period, there is no visible shortening or movement of the muscle fiber.
8. This is because the force generated by the myosin heads is balanced by an opposing force within the muscle, preventing any visible movement.
9. The opposing force is created by the tension in the series elastic elements of the muscle, such as the tendons and connective tissues.
10. This tension allows the muscle to maintain a stable position and prepare for the upcoming contraction.
11. The latent period typically lasts for a few milliseconds, depending on the type of muscle and the intensity of the stimulus.
12. After the latent period, the muscle enters the contraction phase, where the myosin heads continue to bind and detach from actin, causing muscle shortening and generation of force.
In summary, the latent period of isometric contractions is the time between the stimulus and the start of visible muscle contraction. During this period, the muscle prepares for contraction by releasing calcium ions, allowing myosin to bind to actin. However, there is no visible movement because the force generated by the myosin heads is balanced by an opposing force within the muscle.

One recent approach to vaccine development has been production of peptide vaccines. In these vaccines, antigenic peptides are injected instead of whole bacteria or viruses. Peptide vaccines have not been particularly useful against viral pathogens because viral infections require a CD8+ T cell mediated immune response. Why is a peptide vaccine unable to create such a response?
Answer:
Explanation below
Explanation:
Immunization is the process of protecting the body from infections. This can be divided into two, namely
1. Natural immunization
2. Artificial immunization
Natural immunization is the one that is being developed by the body naturally, to protect the body from infections. This is usually known as the white blood cells.
Artificial immunization is being developed through the introduction of atenuated organisms into the body, so that the body can react by producing antibodies against that infectious organisms. This is known as vaccination.
The peptide vaccines have been developed for the body to be able to produce antibodies against some infections.
It should be noted that, owing to the relatively small size of peptides, they are often weakly immunogenic by themselves and therefore require carrier molecules, to add chemical stability and adjuevating for the induction of a robust immune response.

1 pen or pencil
1 ruler
50 small dry beans or other small objects such as buttons
1 small cup
Directions:
1) Use your pen or pencil and ruler to divide the paper into four equal sections.
2) Place the 50 beans into a small cup.
3) Scatter the beans as evenly as possible over the entire paper, making sure to get some of
the beans into each section.
Student Name:
Modeling Population Size
Part Two: Use the Model to Estimate the Size of the Population
In your model, each bean represents a starfish and the paper represents its ocean floor habitat.
1) Within the habitat, choose one of the four sections and count the number of starfish in that
section.
2) Use your ruler to measure the dimensions of the section you chose and calculate the area
that you sampled.
3) Calculate population density based on your sample.
4) Use your ruler to measure the dimensions of the entire habitat and calculate the total
habitat area.
5) Use your calculated population density and total area to estimate total population size.
6) Compare this estimation to your known population size (50). Did you under‐ or
overestimate based on your sample?

Why would the shrimp in the ecosphere die if there was no sunlight?
Answer:
The shrimp would die wthout sunlight because they eat algae and algae live on the water's surface. Algae undergo photosynthesis and for photosynthesis to occur, sunlight is necessary. If there is no sunlight, there is no algae. And without the algae around the shrimp no longer have anything to eat. Therefore, without the sunlight (and algae) the shrimp will not be able to survive.
