Explanation:
why does water enter the paramecium
please answer asap !!!!
Answers
Answer:
As paramecium lives in fresh water, it has the problem of water being transported into it because of osmosis.
Explanation:
osmosis is the movement of any solvent through a selectively permeable membrane into an area of higher solute concentration, the result of which will be an equalizing of solute concentration on either side of the membrane.
Answer:
. Their cytoplasm contains a greater concentration of solutes than their surroundings and so they absorb water by osmosis
Explanation:
Paramecium and amoeba live in fresh water.The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane.

What is affected by the electrical signal sent by the fourth structure of the reflex arc?(This will be the fifth structure in the arc.)
Answers
Answer:
The effector organ is affected by the fourth structure of the reflex arc.
Explanation:
When talking about the reflex arc, we refer to the sequence of events that occur for the body to react to an external stimulus.
In general terms, the peripheric nervous system receives information from a stimulus coming from the external environment. This information is sent to the central nervous system, where it is processed. From the CNS, another signal is sent as a response to the stimulus. This mechanism is known as the reflex arc.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
There are three types of neurons involved in the mechanism:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
Ascending branchThe stimulus reaches the body and is received by the specialized sensory receptors. Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy. Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.
Descending branchOnce the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response. Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.
Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.
Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.

i think B.
Explanation:
Balancing nutrient intake will have the most positive effect on a person's overall physical performance. So, the correct option is (B).
What are Nutrients?A nutrient is defined as a substance that is used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. These are the chemical compounds in food which are used by the body to function properly and maintain health.
Different types of nutrients are as follows:
CarbohydratesProteinsFatsVitaminsMineralsDietary fibreWaterIt is a substance that the body needs for survival, growth and reproduction. It gives us energy and allows our bodies to perform their essential functions. Every organism on our earth needs nutrients which are essential for life.
Thus, balancing nutrient intake will have the most positive effect on a person's overall physical performance. So, the correct option is (B).

Para un carácter existen tres alelos distintos: dos codominantes entre sí y otro recesivo. ¿Cuántos genotipos distintos existirán para ese carácter?¿Cuántos fenotipos?
Answers
Answer:
6 genotipos y 4 fenotipos
Explanation:
La codominancia es un tipo de interacción alélica donde ninguno de los dos alelos puede enmascarar la expresión del otro alelo, produciendo de este modo un fenotipo diferente en presencia de ambos alelos (es decir en individuos heterocigotas). Un ejemplo de alelos codominantes son los alelos A y B del grupo sanguíneo, los cuales se expresan en individuos heterocigotos. Por otra parte, un alelo recesivo sólo puede expresarse en individuos homocigotas que portan dos copias del mismo alelo recesivo. El caso del grupo sanguíneo es idéntico a la pregunta planteada, ya que en este caso tenemos dos alelos codominantes entre sí (alelos A y B) los cuales son dominantes respecto al alelo O recesivo. En este caso, de la combinación de alelos pueden resultar seis genotipos (IAi; IAIA; IBi; IBIB; ii; AB) y cuatro fenotipos (tipo de sangre A, tipo de sangre B, tipo de sangre AB y tipo de sangre O).

which of the following would astronomers most likely measure in light-years distance between stars distance between the earth and the moon?
Answers
Answer:
Astronomical unit usually refers to that unit which represents the mean distance starting from the center of the earth to the center of the sun. The distance from the sun to all the planets and other astronomical bodies are represented in the astronomical unit. It is denoted by AU. This unit is mainly used by the Planetary scientists and the Astronomers, as it is helpful in understanding the relative distance between two objects in the solar system.
Explanation:
Answer:
distance between stars
Explanation:
The distance between the Earth and the stars is enormous. As a result, larger units like light-years are useful for expressing these distances. When a star is eight light-years away from the Earth, the light from that star takes eight years to reach us. To put it another way, the light that we see today originated from that star eight years ago.
The astronomical unit usually refers to the unit that indicates the average distance between the earth's center and the sun's center. The astronomical unit represents the distance between the sun and all of the planets and other celestial bodies. AU is the abbreviation for it. Planetary scientists and astronomers mostly utilize this unit because it aids in determining the relative distance between two objects in the solar system.

a. The incandescent bulb.
b. The compact fluorescent FL) bulb.
c. The LED bulb
Answers
Answer:
10 watt LED bulb.
Explanation:
The most energy efficient is 10 watt LED bulb because it produces more light by consuming less amount of energy. If a substance is more efficient so it consumes less amount of energy for doing its work while on the other hand, less efficient substances uses high amount of energy for doing its work so that's why we can say that 10 watt LED bulb is more efficient its as compared to incandescent bulb and a 17-watt compact fluorescent bulb which uses high amount of energy.
