Catheter is a sterile instrument used to empty the urine straight from the bladder. The process of removal of urine from the bladder using catheter is called catheterization.

The type of catheter which is left within the body is called the indwelling catheter.

The given blank can be filled with decreased and decreased.  

Learned helplessness refers to a state in which an individual suffers from a feeling of powerlessness, resulting due to continuous failure to succeed or due to a traumatic event. It is considered to be one of the main causes of depression.  

In the condition, the cortisol levels of an individual get decreased, which eventually results in the reduction of blood pressure.  

Answer :  Velocity is speed with displacement

Explanation :

The speed of an object is defined as the total distance covered divided by total time taken.

The velocity of an object is defined as the total displacement divided by total time taken.

The speed is a scalar quantity because it has only magnitude while the velocity is a vector quantity i.e. having both magnitude and direction.

The relationship between speed and velocity is " velocity is speed with displacement ".  

Hence, the correct option is (b).

tRNA and mRNA differ in their functions in protein synthesis, where tRNA carries specific amino acids to the ribosome and mRNA carries the codon sequence that dictates the order of amino acids. It is the 3D structure of tRNA that allows it to perform its role; both tRNA and mRNA use uracil, not thymine.

The differences between tRNA (transfer RNA) and mRNA (messenger RNA) are significant in the process of protein synthesis. The correct answer to the question is option b. Only tRNA bends into a specific three-dimensional structure that enables it to carry specific amino acids to the ribosome during protein synthesis. mRNA, on the other hand, is a single-stranded transcript of DNA that carries the genetic code for a protein which is read in sets of three bases called codons, where each codon corresponds to one amino acid.

Moreover, tRNA molecules have anticodons that pair with the codons on the mRNA strand, thus ensuring the insertion of the correct amino acid into the growing polypeptide chain. mRNA does not have amino acid-carrying capacity. Unlike mRNA, tRNA is not involved in carrying the genetic instructions directly from DNA; instead, it plays a crucial role in translating mRNA’s codons into the amino acid sequence of proteins.

It is also important to note that both mRNA and tRNA, like all types of RNA, use uracil instead of thymine. Therefore, the statement in option d, which claims that tRNA uses thymine, is incorrect as thymine is found in DNA, not RNA.

Final answer:

Feminism is an ideology that seeks to achieve gender equality and has evolved through several waves in the United States, from the suffrage movement to contemporary feminist activism that addresses a broad spectrum of issues.

Explanation:

What is Feminism?

Feminism is a movement and ideology that advocates for equality between the sexes, aiming to eliminate sexism and promote equal rights in all spheres of life. Originating as féminisme in French, the concept of feminism has significantly evolved over time. It became widespread in the United States throughout the 20th century, aligning with the Women's Movement that fought for suffrage and later expanded to address diverse women's issues.

Evolution of Feminism in the United States

The first wave of feminism was characterized by the women's suffrage movement, with activists like Elizabeth Cady Stanton working towards gaining the right to vote, which was achieved in 1920. The second wave in the 1960s shifted focus to broader issues such as reproductive rights, equal employment, and challenging gender roles. By the 1970s, feminist activism had made inroads into various fields, including the art world, pushing for equality and representation. Despite differences, by the 1980s, advances such as improved employment opportunities and access to health and education were significant feminist achievements.

Modern feminism encompasses a wide range of perspectives, recognizing the diverse experiences of women, including but not limited to women of color, working-class women, disabled women, and those from different sexual orientations and religious backgrounds. This inclusive approach, as argued by feminists like Barbara Smith, seeks to free all women from the constraints of sexism and societal expectations.

Answer: The correct answer for the blank is -

Cell is the basic structural and functional unit of all life forms, all living organisms are composed of basic unit called cells, and each cell arise from a previously existing cell.

Explanation -

The Cell theory was proposed by Schleiden and Schwann in the year 1839, according to which -

1) Cell is considered as the basic structural and functional unit of all life forms.

2) All life forms are made up of cell.

3) Every cell arise from a cell that already existed before.

Answer:

The correct answer is that X is herding and Y is cooperative hunting.

Explanation:

Herding refers to the act of animals that form groups at the time of grazing in the field. It enhances the protection of the individual member of the group by developing confusion in the mind of the predator. Herding can also enhance the occurrences of finding a mate as the animals stick close to each other, thus, there are exhibits a greater chance of reproductive success.  

On the other hand, cooperative hunting refers to the act of hunting animals in packs. It is generally followed by animals like wolves and lions. These carnivores corner the prey to separate them from their herds and hunt them. This enhances the chances of effectively catching the prey.

Answer: C. The melting ice means less habitat for some marine species.

Explanation:

The melting of ice of Artic sea ice will lead to the increase in the water levels which will be suitable for the survival of some of the aquatic species like krills, whales and fishes. But the animals which thrive over the frozen ice of Artic sea like penguines, polar bear will not survive.Hence, the diversity of the region will reduce.

Answer: C. The melting ice means less habitat for some marine species

Explanation:

Collateral ligaments are two strap-like ligaments that act to stabilize the hinge motion of the knee, preventing any lateral or medial movement. It is the structure that connects the knee joint at both sides and prevents its dislocation. There are two types: Tibial (medial) collateral ligament and Fibular (lateral) collateral ligament.

Explanation:

Peanut butter sandwich combination provides an example of protein complementation. Whenever legumes like beans, lentils, or peanuts are combined with grains like corn, wheat, or rice, a complete protein is introduced. Peanut butter on whole wheat is a snack that is pretty high in calories and provides a huge amount of all the essential amino acids and lots of healthy fats to boot

Protein complementation occurs when incomplete proteins from different plant sources are combined to provide all essential amino acids, like rice and beans combining grains and legumes to create a complete protein profile.

Protein complementation is the process of combining incomplete proteins from various plant sources to provide all the essential amino acids that the body cannot produce on its own. A classic example of protein complementation is the combination of grains and legumes, such as rice and beans. This combination is effective because grains typically lack the amino acid lysine, while legumes lack methionine and cysteine. By consuming both throughout the day, even if not at the same meal, the body receives a complete amino acid profile similar to that found in complete proteins from animal sources.
