How many amino acids must be obtained in the diet because they cannot be made by the body?
2
5
10
20
Please help!!
Answer:
10
Explanation:
Your body can't produce the ten necessary amino acids and must acquire them from your diet.
The body does not manufacture essential amino acids and must be supplied by food. They don't need to take one meal at a time. The equilibrium is more significant during the day.
The body produces nonessential amino acids from essential amino acids or from the natural degradation of proteins.

What is the difference between small, controlled lab experiments versus an ecosystem-scale experiment?
Answer: the number of variables
Explanation:
The difference between small, controlled lab experiments versus an ecosystem-scale experiment is the number of variables.
What is an experiment?A technique used in science to create a discovery, test a hypothesis or prove a known fact.
Lab experiments are done in the lab with a limited amount of variables as there is limited space available.
The ecosystem-scale experiment is performed on large scale and with many variables.
Thus, the difference is the number of variables.

Which of the following observations best supports the cell theory?
Cells come in a variety of shapes and sizes.

How can a material at a certain temperature have all of its molecules at the same energy?
Answer:
A material at a certain temperature does not have all of its particles at the same energy. ... Just because we can assign a single number to the temperature of an object that is in thermal equilibrium does not mean that every atom of the material is moving with the same energy because of the nature of averaging. hope this helps

Before the widespread use of antibiotics, there were very low levels of antibacterial resistance. As antibiotic use has grown, so has the number of antibiotic resistant bacteria. WHY do you think this has occurred?
Answer:
This is because antibiotic resistance can be caused by bacteria getting the ability to be unaffected by the antibiotics Also, people not taking their medication for the entire duration exposes the bacteria to the antibiotic and makes it stronger. Also, when people overuse antibiotics and mutations occur, the bacteria becomes antibiotic resistant.

Explanation:
why do you think are the reasons why only few seeds germinate
Answer:
The germination of a seed can eventually be affected by temperature, humidity and oxygen. Generally, the seeds remain viable longer at low temperatures, a humidity range of 3% to 20% and an environment with low partial pressure of oxygen. If some of these factors are not met, the seed can age or eventually germinate.
Explanation:
Seeds are the main reproductive organ of the vast majority of higher terrestrial and aquatic plants. They play a key role in the renewal, persistence and dispersal of plant populations, the regeneration of forests and ecological succession. In nature the seed is a staple food source for many animals. Seed germination often takes place on the surface of the soil, so the balance between the gain of soil moisture and its loss by transpiration to the atmosphere determines when the seed becomes saturated with moisture and begins to germinate.
The reasons why only few seeds germinate are as a result of some factors such as temperature, availability of water, depth of plant, presence of plant hormone (Gibberellin) in the seed. etc
Seed Germination is a process after seed dormancy where seeds sprout and develop into a new young plant. The reason why some seeds germinate and others do not are some of the following:
Temperature: For the germination of seed to occurs, seed needs to undergo a moderate amount of soil temperature. The cotyledon of the seedling gets destroyed when the seeds are being exposed to an extreme soil temperature. This is why most seed doesn't thrive in the deserts.
Availability of water: The soil in which seeds need to be planted must be moist and contain have a moderate amount of water holding capacity for the survival of the seed plant. The moderate amount of water holding capacity can be seen in humus soil.
Presence of plant hormone: The presence of Gibberellin in seeds helps the activation of the cotyledon to begin the germination process after the seed has absorbed water from the soil. In seeds where the enzymes are absent, such seeds do not germinate.

Which three organs are part of the digestive tract?
A) salivary glands, gall bladder, appendix
B)teeth, tongue, mouth
C)esophagus, stomach, small intestine
D)esophagus, liver, pancreas
Answer:
C
Explanation:
Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso
Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.
The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.
The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.
The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.
The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.
Therefore option C esophagus, stomach, small intestine is correct.
