Answer:
a.
Explanation:
pathogens may enter the body and cause illness.
Immune system is the one that helps to keep away the invading organisms in the body causing disease. A person who has a weakened immune system will not be able to overcome against infection because pathogens may enter the body and cause illness, i.e., option A.
What are pathogens?Pathogens are the organisms or specifically disease-causing organisms that enter the body and alter the functioning of the immune system.
These pathogens can be bacteria, viruses, etc. that can enter through food, water, air, etc.
A weakened immune system can not be able to fight with these invading pathogens and hence leads to diseases.
Thus, the correct answer is A.

Which events are evidence that your brain responds to stimuli in your environment?
Answer:
Answer :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
Step 2 The central nervous system processes information received from the peripheral nervous system.
Step 3 The central nervous system sends out the processed information to the peripheral nervous system.
Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
Explanation:-
There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).
The CNS consists of the brain and the spinal cord .
The PNS consists of all the nerves that lie outside the CNS.
The main function of the PNS is to gather information from the sensory receptors located in our body and convey this information to the central nervous system.
The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action

Answer:
Large groups of the same type of cell, all working together for one purpose.
Explanation:
Human tissues are the group of cells that work together to perform a specific function. In tissues, similar type of cells combine together for performing similar function. The cells in tissue are same type means same size and structure. When a group of tissue combine together, it forms organ. These tissue can be broken down into simpler substances which are the cells that are considered as the basic unit of life.
