Answer:
When a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron, an ionic bond is formed.
Explanation:
The bonds which are produced between a metal ion and a non-metal ion are termed as ionic bonds. Sodium is metal while chlorine is a non-metallic element, ionic bonds are formed in between them.
Sodium has one electron in its outer most shell whereas a chlorine atom has seven electrons in its outermost shell. To become stable, sodium donates its electron to the chlorine atom and hence ionic bond is formed between them.

17. To produce the same intensity and color of light, you can choose from a 60-watt incandescent bulb, a 17-watt compact fluorescent bulb, or a 10 watt LED bulbWhich is the most energy efficient?
a. The incandescent bulb.
b. The compact fluorescent FL) bulb.
c. The LED bulb
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.

why does water enter the paramecium
please answer asap !!!!
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.

B.
Photosynthesis doesn’t produce any ATP, and cellular respiration produces ATP.
C.
Photosynthesis occurs during the day, and cellular respiration occurs at night.
D.
Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
E.
Photosynthesis is an anabolic reaction, and cellular respiration is a catabolic reaction.
Answer:
The answer is E.
Explanation:
An anabolic reaction is one that involves the building of complex substances from simple ones and it uses up energy. Photosynthesis is an anabolic reaction because It requires energy.
A catabolic reaction is one that involves the breakdown of complex substances into simpler ones and in the process energy is released. Cellular respiration is catabolic because energy is released during this process.

Para un carácter existen tres alelos distintos: dos codominantes entre sí y otro recesivo. ¿Cuántos genotipos distintos existirán para ese carácter?¿Cuántos fenotipos?
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).

What Is Dark Matter?
Dark matter is a form of matter thought to account for approximately 85% of the matter in the world. Dark matter consists of particles that do not absorb, reflect or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be directly seen. We know dark matter exists because it affects objects we can directly observe.

Which organisms store some of the molecules from food in their bodies 15 points
to use later as a source of chemical energy and building materials?
animals
plants
both plants and animals
none of the above is correct
Not sure but i think its plants
Both plants and animals store some of the molecules from food in their bodies to use later as a source of chemical energy and building materials.
One of the important characteristics of living organisms is metabolism. Living organisms are able to obtain food which is stored as various chemical substances in the body.
This food materials that are stored as chemical substances are later broken down to produce the energy required by the organism to carry out its activities. Both plants and animals store some of the molecules from food in their bodies to use later as a source of chemical energy and building materials.

Which type of growth can occur only when a population has unlimited resources?
limited
logistic
exponential
negative
Answer:
c. on edge
Explanation:
When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. The correct answer is c) exponential.
What is the exponential growth curve?Exponential growth curves and logarithmic growth curves are the two different forms of growth curves. In an exponential growth curve, the slope increases steadily over time. A logarithmic growth curve has a steeply increasing slope that gradually flattens out over time.
The exponential growth curve, which has a J-shape, shows a period of time where the results develop rapidly and steadily. It is the reverse of gradual progress. This curve initially climbs gradually before accelerating, which represents multiplied growth.
With exponential growth, a population's growth rate per capita (per person) remains constant regardless of population size, causing the population to expand exponentially as it grows larger. In nature, populations may expand exponentially for a while, but ultimately, their growth will be constrained by the availability of resources.
Exponential expansion happens when resources are unrestricted. Due to the favorable conditions, there are a lot more births as a result of the food excess.
Therefore, the correct answer is c).
