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.

13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why
Answer: There are several problems associated with handling of the squid.
Explanation:
Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.
It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.
The maintenance of temperature, and salinity for the squid in aquaculture is difficult.
The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.

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:

What is mid-ocean ridges?The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges.
There is constant propelling of magma, and as the magma cools off quickly it creates new crust.
This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?
Answer:
The correct answer is - as energy lost at every trophic level.
Explanation:
In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.
The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.
As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.
In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.
Thus the response above is right.

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.

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

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.
