name the part of alimentary canal that grinds lumps of food up and mixes it with saliva (without explanation)
Answer: Mouth or oral cavity
Explanation:
The alimentary canal is the long passage through which the food passes. It includes components like mouth, esophagus, stomach, intestines, and anus. It is supplied by digestive juices and secretions by other organs like liver, and pancreas which are not the part of the alimentary canal. Mouth or oral cavity or buccal cavity is the first component of the alimentary canal from where the food enters in the body. It is grinded and masticated by the teeth and mixed with the saliva so that it is converted into liquid form easily swallowed through the gut. The saliva is produced by the salivary amylase enzyme present in the mouth.

What do decomposers leave behind after getting their energy?
А
chlorophyll and vitamins
B
carbon dioxide and water molecules
с
elements like carbon, nitrogen and phosphorus
D
energy-rich carbohydrates
Answer:
C: elements like carbon, nitrogen, and phosphorus
Explanation:
Choice C is the correct answer.
Decomposers leave elements like carbon, nitrogen, and phosphorus behind after getting their energy. Therefore, option C is correct.
What are decomposers?Decomposers are creatures that transform dead plants and animals into humus, a material with a deep brown color. Any ecosystem needs decomposers to function properly. Plants won't obtain vital nutrients if they aren't present in the ecosystem, and they will accumulate decaying objects.
Each contributes to the food recycling process in a different way. To transform dead plants or animals into simple substances, fungi release compounds. Some of these elements are absorbed by them for growth, while others go into the soil. As they ingest dirt, earthworms break down decaying plant and animal debris.
They leave elements such as carbon, nitrogen, and phosphorus after the decomposition of matter. Therefore, option C is correct.

Q4: Manual chewing of food is not enough in order to break down food, enzymes in the saliva and other parts of the body do what? * 10 points Used to lower the activation energy needed for a chemical process They speed up the rate of chemical reactions allowing more productivity They help break down various sugars that can then be absorbed All of the above
Answer:
All of the above
Explanation:
Digestion or breakdown of food in our body can either be physical/mechanical or chemical/enzymatic. As rightly stated in this question, the manual breakdown of food by the teeth is not enough, chemical digestion must occur via the aid of proteinous substances called ENZYMES. Enzymes, which are secreted by certain organs in the body, do the following:
- They speed up the rate of chemical reactions by lowering the activation energy needed for the chemical process, allowing more productivity.
- Enzymes help break down various sugars that can then be absorbed e.g amylase helps break down starch, proteases break down proteins, lipases break down lipids etc.

If each mark on the circle in the model above stands for approximately one day, in about how many days will the moon be in its last quarter phase?
Answer:
7 days.
Explanation:
In 7 days the moon will be in its last quarter phase. In the last quarter phase, the half part of the moon is illuminated and the other half is hide in darkness. The illumination of the sides of the moon provide information about the dates of the month. Last quarter phase is also called third phase of the moon. In this phase, the Moon is in quadrature and has the elongation of 270 degree. It is also the indication that the half cycle of the moon is completed and the other half is started.

What is protein translation?After the process of transcription of DNA to RNA in the cell's nucleus, ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The entire process is referred to as gene expression.
The translation of ribosome of mRNA molecule occurs in three stages: initiation, elongation, and termination. The small ribosomal subunit binds to the beginning of the mRNA sequence during initiation.
The t RNA plays a role in protein synthesis by decoding an mRNA codon and using its anticodon to transfer a specific amino acid to the end of a chain in the ribosome.
Transfer RNA connects the messenger RNA (mRNA) molecule to the growing chain of amino acids that makes up a protein.
Thus, the correct option is B.
