Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.
Answers
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

Three potted plants were kept in a dark cupboard for two days before being used for an experiment. Each plant was then put under a bell jar under different conditions for six hours . Bell jar D contains a potted plant with a small cup of sodium hydroxide solution with light pointed towards it Bell jar E contains a potted plant with light pointed towards it Bell jar F contains a potted plant with aluminium foil on top of the bell jar with light pointed towards it a)explain why their was no starch in the leaves at the end of the two days in the cupboard b)what is the purpose of sodium hydroxide put under bell jar in D?
Answers
Answer:
a. There were starch in the leaves at the end of two days in the cupboard because there was no sunlight to provide the energy for photosynthesis in the dark cupboard. Also, any previously synthesized starch in the plant leaves were used by the plant for its own metabolic requirements during the period the plant was in the cupboard. Therefore, staying in the cupboard for two days destarched the leaves.
b. The purpose of sodium hydroxide put under bell jar in D is to remove any carbon dioxide that may be present under the bell jar. This is to demonstrate that even in the presence of sunlight, carbon dioxide is required for photosynthesis to occur in plants.
Explanation:
Photosythesis is the process by which green plants manufacture their food (carbohydrates which are stored as starch) in the presence of sunlight. The site of photosynthesis in plants is the leaves.
The experimental design is to study the conditions necessary for photosynthesis to occur. For photosynthesis to occur, there must be presence of sunlight, carbon dioxide and water. Carbon dioxide and water serve as the raw materials for photosynthesis while the energy required is provided by sunlight.
The answers to the observations from the experiment are given below :
a. There were starch in the leaves at the end of two days in the cupboard because there was no sunlight to provide the energy for photosynthesis in the dark cupboard. Also, any previously synthesized starch in the plant leaves were used by the plant for its own metabolic requirements during the period the plant was in the cupboard. Therefore, staying in the cupboard for two days destarched the leaves.

Answers
Answer:
C. El sistema respiratorio.
Explicación:
El sistema respiratorio es un tipo de sistema en el que los animales toman del medio ambiente los materiales necesarios para sus actividades vitales. Los pulmones son el órgano principal del sistema respiratorio en el que el gas de oxígeno entra al cuerpo y se almacena en los pulmones a través de la inhalación. La hemoglobina que extrae el gas de dióxido de carbono de la célula lo desecha en los pulmones y carga el oxígeno necesario para el proceso de respiración. El dióxido de carbono se elimina de los pulmones mediante la exhalación.

Answers
Complete question:
Which of the following statements is NOT correct about the flatworms?
A. There are three complete tissue layers.
B. Flatworms may be either free-living or parasitic.
C. Flatworms have a sac body plan, with only a mouth and no anus.
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
E. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Answer:
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
Explanation:
Flatworms are inferior organisms, meaning that they do not have nerves concentrated in a brain. Their nervous system is, in general, composed of nerve cords forming a net. The arrangement depends on each of the groups. They have one or more pairs of primitive eyes, which function is to find the light. These eyes cup-shaped and are composed of pigmentary cells.
Flatworms have bilateral symmetry. Their body is plane dorsoventrally and can be divided into two specular halves by the sagittal plane. This plane crosses through the body from the anterior extreme to the posterior extreme. The frontal plane divides the body into two different halves, the ventral one with the mouth and the dorsal one.
These organisms only have one opening in their bodies directed to the digestive system, which is the mouth.
Flatworms are aquatic and, most of them are marine animals, although there can be a few groups that inhabit freshwater. Some species might even be terrestrial. Most of them are free-living organisms, but there are also some parasitic forms.
