Yes I believe that is true
The body's nonspecific defiance against invading pathogens is known as innate immunity and includes the following:
mechanical barriers and surface secretions
1. The intact skin and mucous membranes of the body. These provide a high degree of protection against pathogens.
2. The sebaceous secretions and sweat of the skin contain bactericidal and fungicidal fatty acids that can kill bacteria and fungi.
3. Normal bacterial flora of the skin may produce various antimicrobial substances such as bacteriocines and acids.
Humoral defence mechanisms
1. Lysozyme. This is an enzyme found in most tissue fluids apart from cerebrospinal fluid, urine, and sweat. It can kill bacteria.
2. Interferon. Inhibits viruses from replicating
3. Complement. This is a heat labile serum that can destroy gram-negative bacteria.
Body temperature control is an example of negative feedback, a process by which the body responds to a stimulus by correcting the change and bringing the body back to the original setting.
What is stimulus ?
A stimulus is a noticeable change in the internal or external environment of an organism's physical or chemical composition. Sensitivity is the capability of an organism or organ to perceive external stimuli and to respond appropriately to them.
The hypothalamus controls your body temperature in a manner similar to how a thermostat controls the temperature in your home. It does this by responding to both internal and external stimuli and making adjustments to keep your body's temperature within one or two degrees of 98.6 degrees.

Explanation:
Cas it goes from very low to high so there not on the same path
Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human
B. putting more red blood cells into circulation when atmospheric oxygen levels decline.
<h3>What are stomata?</h3>
The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.
