If an infant reaches for a toy hidden under a cloth, what does this suggest?
adelina 88 [10]
The correct answer is b.
The child is reaching for a toy which is not visible to him (hidden under a cloth), therefore, the child has a mental representation of the object in his/her mind. This action means that the child acknowledges that the objects continue to exist even when he/she can not hear or see them. This thought process is called object permanence and it is an ability acquired between the 4th and 7th month of a child's development.

4. Which of the following statements best describes how the traits of an organism are determined
butalik [34]

Answer Choices:

DNA provides the energy needed for an organism to grow and function

DNA is copied into mRNA, which controls cellular functions

DNA codes for proteins, which allow an organism to grow and function

DNA unzips and each strand codes for a different amino acid

Answer:

DNA codes for proteins, which allow an organism to grow and function

Explanation:

DNA provides the energy needed for an organism to grow and function  - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.

DNA is copied into mRNA, which controls cellular functions  - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.

DNA codes for proteins, which allow an organism to grow and function  - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>

DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid

Ulleksa [173]

Answer:

I think it might be the last response, since it takes about what some say, 550 million years...

It might be wrong... But take it into consideration that it might be the right answer.

Which of the following shows an unsaturated fatty Acid? Out of those two
SVETLANKA909090 [29]

Answer:

None of these two

Explanation:

An unsaturated fatty acid must contain a double bond in the poly carbon chain other than the double bond in the functional group. In these two, images there exists a double bond in the carboxylic group i.e –COOH.  

Since none of them have double bond in long poly carbon chain, therefore these two fatty acids cannot  be considered as unsaturated fatty acid.
