calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown
Answer:
Kinetic energy of dodgeball = 16 kg-m/s
Explanation:
Given:
Mass of dodgeball = 2 kg
Velocity of dodgeball = 4 m/s
Find:
Kinetic energy of dodgeball
Computation:
Kinetic energy = (1/2)(m)(v²)
Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)
Kinetic energy of dodgeball = (1/2)(2)(4²)
Kinetic energy of dodgeball = (1/2)(2)(16)
Kinetic energy of dodgeball = (32/2)
Kinetic energy of dodgeball = 16 kg-m/s

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

Anoles are a family of IIzards found throughout the Americas. Green anoles, Anolis carolinensis, are native to i specific area of Florida. In this
area, the primary territory of green anoles was once along the ground and in low-level branches. However, the Introduction of brown anoles,
Anolis sagrei, from Cuba forced green anoles to shift o their territory to the tops of trees. The branches at the treetops are smoother and thinner
than those close to the ground. Over time, the toe pads of the green anoles have become larger and stickler.
What is the best explanation for the change In green anoles' toe pads?
Some individuals In the green anole population had mutations that helped them survive and reproduce In the new conditions,
so thelr genes were passed on to the next generation.
O B. Gene flow between the green and brown anoles provided the green anoles with traits that helped them survive and
reproduce, and those tralts were passed on to the next generation.
The feet of the green anoles became larger and stickler as they used them, which helped the green anoles to better survive,
reproduce, and pass the tralt on to the next generation.
O D. The change in conditions caused mutations In green anoles that gave them beneficial tralts for survival and reproduction, and
those mutations were passed on to the next generation.

D. develop technology and resources capable of sending the general population into space on a regular basis
Answer:
D
Explanation:
Develop technology and resources capable of sending the general population into space on a regular basis.
What is Developmental Technology?L. Mumford presented an intriguing theory regarding the origin of technology, contending that biotechnology gave rise to both machine and gun technology.
Technique is derived from the characteristics of how people behave and, in its earliest forms, is directly tied to the origin of man. It was first and foremost life-focused, and only afterwards was it work-focused.
According to L. Mumford, technique with a focus on power and output developed much later. He held that the impersonal aspects of human adaptability to the outside world are what give origin to technology.
Therefore, Develop technology and resources capable of sending the general population into space on a regular basis.

What are evolutionary relationships?
Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:
Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.
The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.
Therefore the correct option is B.

What are the 6 regions of the
human body from which hair can
be derived?
Answer:
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. ... Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life, if that answers your question.
Explanation:
The six (6) regions of the human body from which hair can be derived are:
1. Head.
2. Eyebrow.
3. Beard.
4. Pubic area.
5. Body.
6. Armpit (underarm).
Hair can be defined as a threadlike, keratinous filament that typically grows out of the epidermis. Also, an epidermis is the outer layer of the skin.
Basically, the hair comprises two main parts and these are:
The follicle.The hair shaft.Some of the macroscopic and microscopic properties of hair include:
Hair length.Hair color.Pigmentation of the cortex.Types of scales on the cuticle.Hair curliness.Pattern of the medulla.Generally, hair can be found or grow in different regions of the human body and these include the following:
