Answer:
false
Explanation:
Bacteria are all the same and do not have variations within the species, which is a false statement as the bacteria can undergo asexual reproduction and can show variation within a species.
What is the significance of variation among bacterial species?Variation is common in bacterial species because it benefits them in many ways, such as it affects bacterial virulence, which may make some bacteria more lethal and affect animals and plants than others. The variation can cause the bacteria to become antibacterial-resistant and adapt to a new environment, allowing them to thrive and grow.
Hence, bacteria are all the same and do not have variations within the species, which is a false statement as the bacteria can undergo asexual reproduction and can show variation within a species.

Many years ago, scientists working with cells developed what is now known as the cell theory. The cell theory states: – All living things are composed of one or more cells. – Cells are the basic units of structure and function in an organism. – Cells come only from the reproduction of existing cells. Which of the following observations best supports the cell theory?
Cells come in a variety of shapes and sizes.
Cells have different names for different structures.
Cells can live a very short time.

Explanation:
a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity
Answer:
force
Explanation:
Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.
The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.

How do cells obtain energy?
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
This process is called 'cellular respiration'.
The process is happens in all the cells in our body.
Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

Explanation:
A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.
What is Dichotomous key?More details regarding the unique characteristics of a given organism are disclosed with each successive division. Once the organism no longer exhibits all of the chosen traits in concert with any other organism, it has been recognized.
In order to identify specimens with a dichotomous key, it is recommended to employ immutable traits (i.e. features that do not change). Size, coloration, and behavioral habits can all change across people and over the course of a lifetime.
Better traits are produced by physical features (like the number of limbs) and biological processes (like the mode of reproduction). Typically, dichotomous keys are displayed in one of two ways.
Therefore, A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.

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.

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.
