The answer is Count. Count is an aggregate method in SQL that returns the number of rows for a specified column that have non-null values.

<h3>What is the Meaning of Null?</h3>

When a field in a database has no values at all, this is known as null and indicates that the field’s value is unknown.

A null value for a number field, text field, or space value is different from a zero value. Null indicates that no value has been recorded in a database field.

A value and a null cannot be compared. The Structured Query Language query cannot be written as SELECT * FROM Customer where email Address=null, for instance, if it is intended to obtain all customers without email addresses from a Customer Addresses table.

Answer: D) desmosomes

Options: A) glycolipids B) transport proteins C) tight junctions D) desmosomes

Explanation:  Desmosome is a structure found in cells and has a strong adhesive force, helping cells to bind to other cells and form a sturdy structure. Because the myocardium goes through significant physical activity, desmosomes are necessary in the tissue cells to provide a powerful network between the cells that can withstand more activity than the cells of some other tissues that are not as prone to wear and tear.  They are also found in the epidermis.

Social Learning Theory

Social Learning Theory is the theory that children, as they grow older, learn gender-linked behaviors through observation and direction of their parents, teachers, and peers.

For example, if a young boy was found crying, and his peers made fun of his for crying by saying that "only girls cry," then he would learn that behavior. In this case, social learning theory explains that he is learning gender-linked behavior through his peers' instruction.

Answer:

C). Can enforce James's pledge on the grounds of promissory estoppel based on a charitable subscription.

Explanation:

A charitable subscription is demonstrated as a promise in which a party promises to make a donation to an educational, charitable, or religious institution.

As per the question, Helping Hands Inc. possesses the ability to 'enforce James's pledge on the grounds of promissory estoppel based on a charitable description'. Conventionally, such promises were not enforceable as they are not backed by appropriate legal consideration. But, the modern view allows adding exceptions in the general rule through application of the doctrine of promissory estoppel. Thus, Helping Hands is now allowed to enforce its promise on the basis of promissory estoppel. Hence, <u>option C</u> is the correct answer.

What did Descartes discover in the 2nd Meditation that he cannot doubt? Explain why he cannot doubt this. What is the latin expr
maksim [4K]

Descartes discovers that the physical world does not exist, but because he can doubt the physicality of the world, he must exist.  

Explanation:

In the second Meditation Descartes discovers that the Physical world is not real, or does not exist as it is believed to exist in its permanence. This would imply that Descartes himself does not exist in himself, as he is part of the physical world too.

<u>This leads him to think about his doubts too. The fact that he is able to doubt this existence means that he can see that his existence cannot be doubted. </u>

His existence is thus different from his physical existence.

Then the Latin phrase was come up with that is 'cogito ergo sum' or meaning 'I think, therefore I am.'
