Striated muscles are so-called because of a repeating pattern of light and dark bands. One repeating unit of the banding pattern is called a sarcomere. sarcofibril. myomere. crossbridge. myofilament.
Answers
The term "striated muscles" is used to describe muscles that exhibit a distinctive pattern of alternating light and dark bands. These bands consist of repeating units known as sarcomeres. Hence the first option is correct.
Striated muscles: Striated muscles, also known as skeletal muscles, are a kind of muscle that is accountable for the voluntary movement of the human body's bones. They are also involved in maintaining and maintaining body posture.
The striations in skeletal muscles are caused by the precise alignment of contractile myofilaments within sarcomeres. These myofilaments are made up of the proteins actin and myosin and are responsible for muscle contraction.
Sarcomere: A sarcomere is the smallest functional unit of a muscle fiber. It is responsible for producing muscle contraction by shortening in response to an action potential, resulting in muscle contraction. A sarcomere is defined by two Z-discs, which are composed of proteins that anchor thin actin filaments.
The area between two Z-discs is called a sarcomere and is the basic unit of contraction in skeletal muscles. As a result of the overlapping arrangement of the actin and myosin filaments, the sarcomere appears striated.

Explanation for the difference between measures of human body and Vitruvius ‘ predicted values
Answers
The dimensions of the human body according to Vitruvius') were produced by Italian polymath Leonardo da Vinci about 1490.
Differences ;Leonardo da Vinci created a now-famous depiction of what he thought the perfectly proportioned human form more than five centuries ago: the "Vitruvian Man."
The drawing was inspired by Vitruvius, a first-century A.D. Roman architect who pondered the perfect human form.
Now, research conducted by American experts using high-tech scans of the bodies of nearly 64,000 fit young men (and some women) reveals that Leonardo's measures were remarkably close to those acquired today.
"Despite the diverse samples and techniques of calculation," a team lead by Diana Thomas, a mathematician at the United States Military Academy in West Point, New York, reported.
Leonardo's 1490 picture "Vitruvian Man" depicts an adult male standing, legs together and then apart, inside a circle and square whose borders finish at his head, outstretched hands and feet. It is intended to represent the ideal adult male body. Thomas and her colleagues conducted high-tech 3D body scanning on hundreds of highly fit U.S. Air Force training recruits ages 17 to 21 to ascertain average measurementsA supplementary sample of nearly 1,400 female recruits was also scanned for good measure; nonetheless, the artist did not design a "Vitruvian Woman."The proportional discrepancies between men measured by the body scanner and "Vitruvian Man" were within 10% of one another, the West Point researchers reported, with the exception of arm span and thigh length. "The disparity in thigh height was 29% more than "Vitruvian Man," while the difference in arm breadth was 20% greater."In other words, the fingers and toes of the modern "ideal" man are somewhat larger than the borders of Leonardo's flawless circle and square.However, Thomas' group was willing to give the Renaissance genius some leeway, pointing out that population averages could not have been calculated scientifically in the 15th century and that Tuscan men's measures might have been different from those of young American men today.To know more about Vitruvian man please click here : https://brainly.com/question/27046318

What are the four reasons why Mendel choose garden pea for his experiment?
Answers
Mendel chose garden pea for his experiment because they have shorter life span, are bise-xual, self pollinating and have visible physical characteristics.
Mendel conducted a lot of experiments during his study in genetics. He considered garden pea ideal for his experiments for a number of reasons. The first reason being that garden pea has a short life span and because of this they are able to grow very quickly and are easy to maintain. The second reason is that they have visible physical characteristics which makes them easy to observe and study.
The other two reasons being that garden peas have bise-xual flowers and because of this, these garden peas are self-pollinating. They do not need another plant for pollination and can also easily cross pollinate.

d. an input of energy to attach a third phosphate group.
Answers
In the initial stages of photosynthesis, a process known as photophosphorylation uses solar energy to convert ADP to ATP.
How is adenosine diphosphate ADP different from ATP in terms of structure?ADP will include two phosphate groups (thus the diphosphate), whereas ATP will still contain all three phosphates. This is the primary structural difference between adenosine diphosphate (ADP) and adenosine triphosphate (ATP) (hence the triphosphate). When ATP's one phosphate group is hydrolyzed, ADP is produced.
Does ATP undergo oxidation or reduction to become ADP?The phosphate group, which has available electrons, transfers electrons during the conversion of ATP to ADP. An oxidation reaction occurs when a phosphate group in ATP is removed; this process also removes electrons.

under what conditions does one expect a 9:3:3:1 ratio?
Answers
A 9:3:3:1 ratio is expected in the F2 generation of a dihybrid cross involving two heterozygous parents.
This ratio represents the phenotypic outcome of the offspring, with:
9 showing the dominant phenotype for both traits, 3 showing the dominant phenotype for one trait and the recessive phenotype for the other, 3 showing the recessive phenotype for one trait and the dominant phenotype for the other1 showing the recessive phenotype for both traits.This ratio is derived from the Punnett square, where the possible gametes of each parent are listed along the top and side, and the possible offspring genotypes are listed in the squares.
The 9:3:3:1 ratio is a result of the independent assortment of alleles during meiosis, where the alleles for each trait separate independently of one another.
In summary, a 9:3:3:1 ratio is expected under the following conditions:
- Dihybrid cross involving two traits
- Both parents are heterozygous for both traits
- Independent assortment of alleles during meiosis

The moth population is an evolutionary example of directional color change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-colored moths increased around this time, an example of industrial melanism.
What is the function of the moth?Lepidoptera, a group to which butterflies and moths belong, are important elements in nature. They serve as food for a multitude of animals, control populations of invasive plants and, especially, promote plant pollination.
What is the difference between moths and butterflies?Butterflies leave their wings together in an upright position when they are at rest. But moths leave their wings open, extended horizontally over the body. Finally, we can also differentiate them by their antennas. Butterflies have clavate antennae, that is, thin with a dilated tip.

Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. Suppose a spitting cobra rears up to a height of 0.420 m above the ground and launches venom at 3.70 m/s, directed 55.0
∘
above the horizon. Neglecting air resistance, find the horizontal distance (in m ) traveled by the venom before it hits the ground. cm
Answers
The horizontal distance traveled by the venom before it hits the ground is approximately 2.71 meters.
How far does the venom travel horizontally before reaching the ground?To calculate the horizontal distance traveled by the venom, we need to analyze the projectile motion of the venom's trajectory.
By considering the initial height, launch velocity, and launch angle, we can determine the horizontal distance covered.
When the spitting cobra launches venom, we can treat it as a projectile motion problem in the absence of air resistance.
The initial height of 0.420 m and launch angle of 55.0 degrees above the horizon are given.
By using the equations of projectile motion, we can calculate the time of flight and the horizontal distance traveled by the venom.
Using the equation for horizontal distance:
Range = (launch velocity) × (time of flight) × cos(launch angle)
By substituting the given values, we can calculate the horizontal distance covered by the venom.
Neglecting air resistance simplifies the calculation, as the venom's motion is only influenced by gravity.
Therefore, the horizontal distance traveled by the venom before hitting the ground is approximately 2.71 meters.

pongids: a. are incapable of walking bipedally b. can walk bipedally only by holding on to branches with their arms c. are capable of bipedal locomotion, but inefficiently d. are, in fact, habitually bipedal
Answers
One of the earliest adaptations made by hominids was bipedalism, and there are several theories as to how the human ancestors acquired it. One of them claims that after a group of our ancestors started living in Savannah habitats, bipedalism emerged (open areas covered with grasses). The Savannah lineages didn't have many trees to climb, so the upright posture let them see predators in the distance. Other lineages remained in the forests, where they could use the treetops and branches for protection and to collect food.
The second theory links the use of tools to the evolution of human bipedalism. The two forelimbs are free to explore the environment, aid in the use of tools, and even gather food while moving because a species does not move on all four limbs.
With this knowledge, we can conclude that bipedalism gave the human race a free arm to build technology and allowed them to move more slowly while walking, among other benefits.

Answers
Option A is correct - The pakicetus species lacks tail flukes. Due to distinctive inner ear characteristics that are unique to cetaceans, Pakicetus was categorized as an early cetacean.
The amphibious cetacean genus Pakicetus, which is extinct, was endemic to Pakistan during the Eocene, roughly 50 million years ago. It belonged to the family Pakicetidae.
It was a wolf-like creature that ranged in length from 1 meter (3 ft 3 in) to 2 m (6 ft 7 in), lived near water, and fed on fish and other small animals. Most paleontologists think of it as the most primitive whale, standing in for a stage between land mammals and whales.

which is not involved with an inflammatory Response
A. Fever - increased temperature
B. Slowed blood flow
C. White blood cells move to the area of infected
D. inflammation in area
Answers
Reasoning: a fever is caused by the body trying to kill off any unwanted pathogens with the heat. This is an inflammatory response to the body being infected.
White blood cells move to the infected area in an attempt to kill any pathogens. Since white blood cells are mainly meant to help kill pathogens, it is an inflammatory response to send white blood cells to kill the pathogen.
Lastly, inflammation is caused by the body trying to rid the infected area of the pathogens. Similar to the name “inflammatory”, the body will often cause inflammation in an attempt to get rid of any unwanted pathogens in the body.
This is an inflammatory reaction to an infection in the body. Option D is correct.
What is the inflammatory response?When tissues are harmed by toxins, germs, trauma, heat, or any other cause, the inflammatory response (inflammation) ensues. A fever is induced by the body's attempt to destroy any infections with heat.
Histamine, bradykinin, and prostaglandins are among the substances released by injured cells. Because of these substances, blood vessels leak fluid into the tissues, producing swelling.
White blood cells migrate to the affected location to destroy any germs. Because white blood cells are primarily intended to aid in the killing of infections, sending white blood cells to destroy the pathogen is an inflammatory reaction.
Finally, inflammation results from the body's attempt to cleanse the contaminated region of microorganisms. Similar to the label “inflammatory,” the body will frequently create inflammation in an attempt to cleanse the body of any undesirable infections.
Therefore, option D is correct.
