Name and give examples of 2 major types of mutations. What do they have in common? How are they different?
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.
Which of these is not a human cause of extinction of species?
Choose the correct answer.
A) Clearing of an area for farmland.
B) A dam built in a river for city water usage.
C) Competition for food resources with another native species.
D) The introduction of a new predatory species to an island by boat.
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.
What is species?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.

Explain why it is important to study ocean microbes with regard to the biosphere.
Answer:
Studying marine microbes is very important because it controls the major biogeochemical cycles that balance the Earth's biosphere.
Explanation:
Answer:
They are also major pillars of the biosphere. Their unique metabolisms allow marine microbes to carry out many steps of the biogeochemical cycles that other organisms are unable to complete. The smooth functioning of these cycles is necessary for life to continue on earth.
Explanation:
reasons for seasons
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.

Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
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.

5 5. Normally, the temperature inside the scrotum is slightly lower than normal body temperature. What do you predict would happen if the temperature inside the scrotum were a few degrees higher than normal body temperature instead? A. Sperm would not be able to travel through the vas deferens. B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,
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.
What is the function of "sc-rotum"?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.

which of the following is least likely to be an example of a transference situation?
Transference is a psychoanalytic term that refers to the phenomenon in which an individual's feelings and emotions are unconsciously transferred from one person to another.
Transference occurs when people project onto others the emotions and attitudes that they once held towards significant figures in their past lives such as their parents, teachers, and early caregivers.
The following is the least likely example of a transference situation: An individual who dislikes his therapist for the first few sessions due to the therapist's personal habits (such as tapping his pen on the desk) but eventually comes to realize that the source of the negative emotions was the individual's own unresolved feelings about his father who used to make a similar noise.
The other options are more likely examples of a transference situation: An individual becomes romantically interested in his therapist, projecting onto the therapist the love and affection he once felt for his mother. A client who is unconsciously angry with her father is hostile towards her therapist, transferring her anger to the therapist, whom she unconsciously associates with her father.
An individual who feels insecure and inferior in social situations responds to his therapist with fear and trepidation, projecting onto the therapist the feelings he had towards his early caregivers.

okazaki fragments are associated with the_____strand that demonstrates discontinuous nucleotide synthesis. these fragments are synthesized in the_____direction.
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.

what is the most serious drawback to using library screening to study genetics?
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.
What is Library screening?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.
What are the other disadvantages of library screening?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.
