Answer:
Option b=> hearing.
Explanation:
When information are getting to individual without the person using his or sense organs such as the eyes(vision), ears(audio/hearing), skin(feeling), tongue (tasting) and nose(perceiving smell) then we say that the individual has '' psychic powers'' or the sixth sense.
extrasensory power.
If you look at the meaning of option (a), that is clairvoyance, it is more of seeing the future which can never be seen with our normal eyes, therefore, it is an extrasensory power
Option (b), can be done with our normal ears, hence, it is not an extrasensory power.
Option (c) and (d) that is precognition(knowing what is coming without seeing with norm human eyes) and telepathy(being able to read People's mind) respectively are both extrasensory powers.
B:Fever increases body temperature and speeds up the body's reaction to pathogens.
C:Phagocytes identify cells invaded by pathogens and mark them for destruction.
D:Mucus traps pathogens and destroys them before they can enter the body.
Hey there! I took the test, and I can confirm that A. Cytotoxic T cells are activated and destroy cells that pathogens have invaded. is the correct answer
God bless ❤️

Answer:
The correct option is;
The number of adenine bases will be equal to the number of thymine bases
Explanation:
The four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism
The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;
Adenine (A) pairing with thymine (T)
Cytosine (C) pairing with Guanine (G)
Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.
Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.
According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.
Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.

Bacteria and archaea differ in their cell walls makeup.
Further Explanation:
Archaea is considered to arise many years ago and is also considered to be the most primitive form of life. Earlier they were classified as bacteria but as they possessed certain difference features when compared with bacteria, it was now termed as archaea. Some of the characteristics of archaea resembles eukaryotes while other resembles with prokaryotes.
Archaea are single celled organism and they can thrive in harsh conditions like marshy area and hot springs. Some of the example of archaea are, Thermococcus litoralis, Methanopyrus kandleri, Cenarchaeum symbiosum etc.
The features of archaea which are similar to bacteria are:
1. Lack of nuclear envelop.
2. Lack of membrane bound envelop.
3. Presence of circular chromosomes.
The features of archaea which are similar to eukaryotes are:
1. Methionine is the initiator amino acid for protein synthesis.
2. Lack of peptidoglycan in their cell wall.
3. Association of histones with DNA.
