1. Fallopian tube
2. Uterus cavity
3. Bladder
4. Urethra
5. Ovary
6. Ovary
7. Uterus
8. Vagina
Explanation:
The vagina is a muscular tube-shaped connection that extends from the vaginal opening to the uterus. Vagina walls are very muscular, which allows contraction and expansion movements. It is located just between the urethra/bladder and the rectus. Menstruation, copulation, and birth occur through the vagina.
The uterus is a muscular and hollow organ, also located between the bladder and the rectus. The uterus wall is formed of three layers: perimetrium, mesometrium, and endometrium. This organ is separated into two parts: the uterus body and the cervix, which protrudes to the superior area of the vagina. Here is located the uterine opening that communicates the vagina with the uterus cavity. The final rounded portion is called "uterus fundus", and each of the two extremes is called "uterus horn". These horns are united to the Fallopian tubes.
Fallopian tubes are ducts that communicate each of the ovaries with each of the uterus horns. These tubes receive the oocytes that are getting out of the ovaries and carry them to the uterus. In their way, they might meet a spermatozoid and be fertilized.
Both ovaries have an oval shape, of approximately 3 cm in length each and 1 cm in width. They are located at each side of the uterus and are in charge of the production of the feminine gametes (the whole ovulation process).

Question: Innate immunity:
a) is based on recognition of antigens that are specific to a pathogen.
b) is the first and most general, mechanism of protection against pathogens
c) is found only in vertebrates
d) depends on an infected animal's previous exposure to a pathogen
Answer:
b) is the first and most general, mechanism of protection against pathogens
Explanation:
Innate immunity is the nonspecific immune response that provides immediate and the most general protection against all types of pathogens, parasites, toxins and cancer cells. Innate immune responses serve to prevent the pathogens from entering the body. The components of innate immunity also rapidly destroy those pathogens that have entered the body.
Some of the components of innate immunity are the first line of defense such as the physical and chemical barriers of the skin and mucous membranes. The components of the second line of defense such as natural killer cells, phagocytes and inflammatory response are also involved in innate immune responses.
For example, cuticle or skin serves as a physical barrier to pathogens that come in contact with an animal’s body. Phagocytosis kills the bacteria that invade the body.
Answer:
Seaweed (producer) → Shrimp (primary consumer)→ Crab (secondary consumer) → Octopus (tertiary consumer)
Explanation:
In a food chain, there are organisms of different trophic levels present. Food chain, the chain or linear network or representation of a line of the food web that always starts with a producer as sea-weed in the given food chain and ends with a predator or third or highest consumer which is Octopus here and in between the different level of consumers from the primary consumer that depends on the producers and secondary consumer depends on primary and so on.
Seaweed (producer) → Shrimp (primary consumer)→ Crab (secondary consumer) → Octopus (tertiary consumer)
