Answer:
The correct answer is: tissue.
Explanation:
Humans are made of organ systems, organ systems are made of organs, and organs are made of tissues. These <u>tissues are all composed of specific cells that work together in order to carry a particular task that is demanded by the body</u>.
There are four basic types of tissue: epithelial tissue (found in the surface of the skin and in the inner lining of hollow organs), muscular tissue (has the ability to contract), nervous tissue (regulates and controls bodily functions), and connective tissue (connects all of the other organs).
A direct observation usually refers to observing a behavior and knowing exactly what is happening. For example, if I see a pigeon peck at some bread, I have observed it pecking. With direct observation, I cannot assume it is eating, that it is hungry, that it has any intention whatsoever. All I know is that it pecks.
Answer:
They belong to the same species
Explanation:
A karyotype is an image of the chromosomes of a cell usually taken by an atomic microscope in a cell arrested in the prophase stage of mitosis –because the chromatin is well condensed.
It is difficult to discern the difference between individuals of the same species using karyotype unless in exceptions of chromosomal disorders like Klinefelter's syndrome and Turners syndrome, and etcetera.
However different species will most likely differ in the number of chromosomes, the chromosomal sizes and their arms lengths.
Answer:
perform functions that tissues cannot carry out on their own
Explanation:
In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.
A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.
Answer:
ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.
