Hope this helps :)
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
The fact is not included, thus the question cannot be answeredZ
Answer:
Ovary
Explanation:
Anthophyta or the angiosperm are the plants which bear reproductive structure in a colorful modified shoot called flower.
The flower contains both male and female reproductive structures. It is the female reproductive structure that develops into the fruits when the female egg cell is fertilized with the sperm.
The female reproductive structure is made of the style, stigma and the ovary. The ovary encloses the egg cell which after fertilization becomes an embryo and the ovule turns into the seed and the ovary turns into the fruits. That is why the fruits bear the seeds.
Thus, the ovary is correct.
Answer:
motor cortex association
Explanation:
The motor cortex is one of the parts of the telencephalon, which in turn is part of the brain. Its main function is to favor movement. Then through it we generate, maintain and finalize the movements.
Thanks to the motor cortex we can make voluntary movements consciously. This brain region is located in the frontal lobe, just in front of Rolando's fissure and somatosensory region.
If the part of the brain where the motor cortex is located is injured, movement of some part of the body may be lost or limited. For this reason, if Marta lost her arm movements after a brain injury caused by an accident, we can conclude that this injury injured the motor cortex.
