The larynx is an nicknamed the "voice box" because it holds the vocal cords inside. It helps change the pitch and volume of our voices as we speak. It is the only part of the body capable of doing this job, so we don't ever want it removed. Our voices would be much more monotone sounding. The larynx connects the pharynx to the trachea in the neck. It is also capable of allowing air through for us to breathe, but does not let anything (food or drink) block the airway. This is obviously a daily function since we eat and drink numerous times daily and usually have no problems breathing while eating and drinking. This is thanks to the larynx.
Hope this helps! :)
Answer:
B
Explanation:
I learned this 2 years ago
Answer:
Trophic level
Consumer
Producer
Explanation:
All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.
A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.
Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.
In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.
Most of the mutations have no effects whatsoever on the organisms but some can be dangerous. There are two types of mutations that cause harm to the organism's ability to survive:teratogen muations are the mutations that form inside the uterus when the fetus is still developing and can even kill it or cause severe malformations that lead to death in the early life. Carcinogen mutations are the ones that lead to the formation of neoplasms(masses of cells that divide uncontrollably, basicly cancer).
Answer: (A) a membrane‑bound organelle with stacks of thylakoid discs called grana.
(E) the main site of photosynthesis in a plant cell.
Explanation:
The plant chloroplast is a large organelle, it is bounded by a double membrane like structure that is chloroplast envelop.
The chloroplast consists of chlorophyll pigment which traps the light energy from sun and converts it into chemical energy in the form of ATP. Thus the chloroplast is the main site for photosynthesis. Including the inner and outer membrane structure it also posses the third internal membrane structure which is called as the thylakoid membrane. The thylakoid membrane forms the network of flat discs which are called as thylakoids, the thylakoids are arranged in stacks which are called as grana.
The thylakoid membrane is the center point for the synthesis of ATP through a chemiosmotic process.
