Answer:
bolus,chyme and feces
Explanation:
The enzyme in the saliva digests starch to maltose. The tongue rolls the food into small round masses called boluses, then pushes the bolus into the pharynx for swallowing.
The stomach wall is made up of thick circular and longitudinal muscle layers. These muscles contract and relax producing movement that aids in the mixing of the contents of the stomach. This mixing is known as churning and results in the formation of a fluid called chyme.
The remaining semi-solid waste material is then passed to the rectum where it is stored temporarily and eventually eliminated from the body as feces through the anus as the sphincter muscles relax.
C. Aa heterozygous is a capital letter with a lowercase letter
Answer:
Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?
Answer:
A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C
Explanation:
Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).
That automatically eliminates Option B.
I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.
Option D is wrong because it includes no temperatures above body temperature.
Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.
That leaves Option A as the best answer. It includes only one temperature above 40 °C.
