Recognition of poisonous plants is very important since it is part of livestock managements especially grazing animals such as cows and horses. Plant identification and avoidance to such is the key solution to poisoning.
Here are five plant species that are poisonous to grazing animals:
1. Brackenfern- <span>(Pteridium acquilinum)
2. Butterfly Milkweed (</span><span>Asclepias tuberosa)
3. Chokecherry (</span><span>(Prunus virginiana)
4. Cocklebur (</span>Xanthium strumarium)<span>
5. Hoary Alyssum </span><span>(Berteroa incana)</span>
We all know what we mean when we say a moving car has<span> energy or the .Work is done when a force is applied on a </span>object<span> through a given distance. This energy is not lost, rather is stored in the box as </span>gravitational potential energy<span> A bucket of water with </span>mass<span> 10 </span>kg<span> is raised at constant speed to the top of a 10 meter</span>
There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).
- Evolutionary biologists believe that the "fight or flight" response was crucial for the survival of many species throughout Geologic Time.
- Both the sympathetic and parasympathetic nervous systems are vital to our health and survival.
- The neural system of all animals is composed of highly specialised cells called neurons which can detect, receive and transmit different kinds of stimuli.
- When the "fight or flight" response has been activated of the autonomic nervous system called the sympathetic division controls this response.
What is human nervous system?
- The human nervous system is divided into two parts,
1. The Central Neural System(CNS)
2. The Peripheral Neural System(PNS)
- The CNS includes the brain and the spinal cord and is the site of
- information processing and control.
- The PNS comprises of all the nerves of the body associated with the CNS i.e., brain and spinal cord.
- The nerve fibres of the PNS are of two types :
1. Afferent fibres
2. Efferent fibres
- The PNS is divided into two divisions called;
a. Somatic neural system
b. Autonomic neural system
- The somatic neural system relays impulses from the CNS to skeletal muscles while the autonomic neural system transmits impulses from the CNS to the involuntary organs and smooth muscles of the body. The autonomic neural system is further classified as;
(i) Sympathetic neural system
(ii) Parasympathetic neural system
