Answer:
the answer is D. indentifying the father of a child
(type of food), and both the number and percentage of the total food items eaten by each type of bird. Create a bar graph of percent food eaten with 36 bars (a bar for each of the six species in environment 1, env. 2, etc.) using a program like Excel. Label your graph, and color code the bars for emphasis. Include a legend which indicates the color of each species. Try this pre-built Excel table to enter and graph your data...... I hope this gives an idea or all you were looking for. Take care.
The peripheral nervous system receives information from the environment and relays commands from the central nervous system to organs and glands.
<h3>What is the peripheral nervous system?</h3>
The nerves that emerge from the brain and spinal cord make up the peripheral nervous system. The CNS and the body components are connected through a network of nerves. The somatic nervous system and the autonomic nervous system are additional divisions of the peripheral nervous system.
The somatic nervous system and the autonomic nervous system are two subsystems of the peripheral nervous system. With the exception of the optic nerve (cranial nerve II) and the retina, the cranial nerves make up the PNS in the somatic nervous system. The second cranial nerve is a tract of the diencephalon and not a real peripheral nerve. The CNS is where the cranial nerve ganglia were born. The PNS, however, is thought to include the ten remaining cranial nerve axons because they travel outside of the brain. Smooth muscle and glands are subject to involuntary control by the autonomic nervous system. The sympathetic and parasympathetic states of the system are made possible by the relationship between the central nervous system and the organs.

Decomposers are living organisms that breaks down other living and non-living things into smaller parts.
Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals.
Ans.
Gill slits or pharyngeal slits are defined as opening structures to throat, pharynx, or fish gills, by which passage of water from pharynx to exterior takes place in fishes. In primitive chordates, gill slits help in filtration of particles of food from surrounding water. In amphibians and fishes, gills are used for the gaseous exchange. In chordates that live in lands, such as mammals, gill slits found in developing embryos only.
Thus, the correct answer is 'option D). all chordates' as gill slits are present in all chordates at some stages of their development.
