The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.
Answer:
Grass - grasshopper- man - bacteria.
Grass - rabbit- man - maggot.
Grass - cow - man - bacteria.
Explanation:
In these food chains, grass is the producer that provides food to primary consumer or herbivores such as grasshopper, cow and rabbit. These primary consumers are the food of secondary consumer such as human while when human die, it become the food of worms and decomposers such as maggot, bacteria etc. the nutrients releases by decomposers are used by producers for the production of food for themselves.
The answer to this question would be: (4)carnivoresFood made by autotrophs which makes them placed first in food webs as they produce food. After that, the herbivore can digest the food made by autotroph, makes them places as the first consumer. Carnivores is the organism that eats meat, makes them the last consumer.

Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
