There are 5 essential amino acids that are needed to make a complete protein. True of False
Aliun [14]
False. There are actually 9 essential amino acids that are needed to make a complete protein that is necessary for the dietary needs of a person. These amino acids includes Tryptophan, Isoleucine, Threonine, Lysine, Leucine, Valine, Methionine+Cystine, Phenylalanine+Tyrosine and Histidine. Generally, a complete protein can be gained from animal foods such as fish, poultry, animal meats and eggs, but it can also gain from selected plant foods as well.

Describe the need of conservation of biodiversity​
Rufina [12.5K]

Answer:

Biodiversity conservation protects the plant, animal, microbial and genetic resources for food production, agriculture, and ecosystem functions such as fertilizing the soil, recycling nutrients, regulating pests and disease, controlling erosion, and pollinating crops and trees.

Plants and animals depend on each other in order to survive, therefore the destruction of one would affect the life of the other. Hence, we should conserve biodiversity to prevent these species to become extinct and to maintain a balance in nature.

The aerobic exercise helps to increase:__________
g100num [7]

Answer:

b) Cardio respiratory

Explanation:

Just as exercise strengthens other muscles in your body, it helps your heart muscle become more efficient and better able to pump blood throughout your body. This means that the heart pushes out more blood with each beat, allowing it to beat slower and keep your blood pressure under control. Aerobic exercise boosts your good cholesterol (HDL), and lowers your bad cholesterol (LDL).

Hope this helps ya! Best of luck <3
