Answer:

0.7

Explanation:

Given that in statistics, the Relative Frequency is the Frequency of the class divided by Total.

Hence, in this case, the Relative Frequency of black hair is the Frequency of black hair divided by the Total.

Hence, we have 70 ÷ 100

=> 0.7

Therefore, the correct answer is 0.7 Relative frequency.

The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.

In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.

But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.

Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

Answer:

D. 4 times as great

Explanation:

The inertia of an object is the resistance offered by the object to change in its motion or position.

Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.

This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.

From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma

Where m is mass of object, a = acceleration of the object.

Objects on the earth's surface experience a constant acceleration, g.

Thus for a 1 kg mass, Inertia = 1 × g

For a 4 kg mass, inertia = 4 × g

The inertia of a 4 kg mass is four times as great as a 1 kg mass.

The inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great

Inertia is the property of matter that resists changes in motion. Mass is the quantitative matter of motion.

Thus, the inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great.

Okazaki fragments are associated with the lagging strand that demonstrates discontinuous nucleotide synthesis. These fragments are synthesized in the 5' to 3' direction.

During DNA replication, the lagging strand is synthesized in short, discontinuous fragments known as Okazaki fragments. This is because DNA polymerase can only synthesize DNA in the 5' to 3' direction. On the lagging strand, synthesis occurs in the opposite direction of the replication fork movement, resulting in the need for Okazaki fragments. These fragments are initiated by RNA primers that provide a starting point for DNA synthesis. DNA polymerase then elongates the fragments in the 5' to 3' direction, away from the replication fork. The fragments are eventually joined together by DNA ligase to form a continuous strand.

Answer:

Both realized niche and fundamental niche are similar in size.

Explanation:

If Chthamalus’ and Balanus’ respective niches were a result of niche differentiation so we can say that Chthamalus’ realized niche is not smaller than its fundamental niche. It will be of the same size because of no interspecific competition with Balanus. The whole fundamental niche is considered the niche of the Chthamalus' alone due to no competition with Balanus' for resources present in the ecosystem.

Answer:

The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.

Explanation:

Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.

Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:

--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.

--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.

--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.

Therefore, these structures helps the plant survive in its present environment.

Answer:

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth's axis, we wouldn't have seasons.

Answer:

The correct answer would be - Two major types of mutations are deletions and substitutions.

Explanation:

The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.

The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new  DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.

Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.

Answer:

C. Sperm would not be able to develop properly.

Explanation:

There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.

If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.

A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.

Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.

Thus, the correct answer is option C.

The most serious drawback to using library screening to study genetics is that it can result in the identification of gene fragments that are not in the correct orientation or order.

Library screening is a procedure that allows researchers to isolate clones that express a specific protein or contain a specific gene. A genomic library or a cDNA library may be used for this technique.

The other disadvantages of library screening are given below: Library screening, when compared to PCR, is a relatively time-consuming and labour-intensive process. Library screening's capacity to recover a specific gene is highly dependent on the library's quality, complexity, and redundancy. A library may lack certain sequences that are required to discover the gene of interest.

There may be errors or ambiguities in the data collected by the researchers. In a library, the sequences discovered may not necessarily be the most significant for research purposes.
