What are the differences between the endocrine and nervous systems?
son4ous [18]

Answer:

Explanation:

The endocrine system is a complex of glands that secrete <u>hormones</u> as a chemical messenger. These hormones carry information and instructions throughout the bloodstream from one part of the body to another. These hormones control many body functions such as respiration, sensory perception, metabolisms, growth, reproduction, the mood among others.

On the other hand, the nervous system is made up of neurons that communicate with each other to extend a message (from our own body or the outside) to the brain, for analysis and further decision of what to do with that information. A group of neurons, sensory neurons, respond to several stimuli such as touch, light, and sound to let the brain know about the surrounding environment. Another group of neurons, motor neurons, work inside the body and carry signals to active muscle or glands.

Sea weeds come under polyphyletic group of the phylogeny.

What is phylogeny?

Phylogeny is the study of a species' or group's evolutionary history, particularly as it relates to relationships and lines of descent among large groups of animals.

The idea that distinct species of plants or animals descended from a single ancestor is fundamental to phylogeny and is widely recognized in the scientific community. Since the majority of animals that have ever existed are extinct and only a small portion of their fossilized remnants have been preserved in the fossil record, the evidence for these relationships is almost always insufficient. Therefore, the majority of phylogenies are based on inferential data and are hypotheses. Commonly, different phylogenies can be inferred from the same evidence.

Food chains always start with which kind of organism? Question 3 options: Decomposer Consumer Carnivore Producer
Valentin [98]

Answer:

Producers!

Explanation:

Autotrophs are the foundation of every ecosystem on the planet. That may sound dramatic, but it's no exaggeration! Autotrophs form the base of food chains and food webs, and the energy they capture from light or chemicals sustains all the other organisms in the community. When we're talking about their role in food chains, we can call autotrophs producers.
