A plant growing toward a light source is an example of an organism..
A: attracting a mate
B: destroying infectious germs
C: responding to external stimuli
D: obtaining moisture from the air
Answer:c
Explanation: The plant is responding to external stimuli by growing toward light like our eyes adjusting to the light in the dark......................
The correct answer is option c i.e. responding to external stimuli (phototropism).
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.
what is phototropism?
Phototropism is one of the many plant tropisms or movements which respond to external stimuli.
Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.
Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light.
Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower—switch to reproductive mode—only at certain times of the year.
hence , a plant growing towards a light source is an example of phototropism.

conduction of water by root pressure and suction pressure
Answer:
Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground.

A biology teacher gives each pair of students in her class a group of 30 newly sprouted bean plants. She tells the class to design and carry out an experiment with these plants. After one month, the students compile the data shown below.
Answer: I think It's D
The conclusion that can be made from the experiment is that the difference in growth between group 1 and group 5 seedlings shows that light impacts plants' growth.
Group 1 plants were exposed to 12 hours of light per day while group 5 plants were not exposed to light at all.
At the end of the experiment, group 1 plants produced a significantly higher number of leaves (8) and grow far taller (13 cm) than group 5 plants who were only able to produce a single leaf and grew 4 cm tall.
Also, the majority of group 1 plants were alive after 30 days of the experiment while the majority of group 5 plants had died.

Determine if each picture is a high or low tide.
Note: only ONE picture can be a high tide and only ONE picture can be a low tide!
Answer: the first picture is low tide
Explanation: on the first picture the boat in the center isn't in the water and on the second picture the waves are more agressive which happens with a higher tide
Answer:
The first picture with the boat is low tide. You would not park your boat so shallow so it would be low tide. The second picture with the waves is high tide. Big waves tend to bring in the high tide.

What best explains why a person can become sunburned by spending too much time at the beach?
Sunlight is an electromagnetic wave that gains energy as it travels through air to reach the person.
Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin.
O Sunlight is a mechanical wave that vibrates the skin particles to produce heat.
O Sunlight is a mechanical wave, and its frequency matches the natural frequency of skin to make heat.
Answer:
Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin.
Explanation:
A person can become sunburned as
B. Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin.
Sunlight as an Electromagnetic wave:Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.
Sunlight is an electromagnetic wave that gains energy as it travels through the air to reach the person.

how cellular transport is beneficial to cells, and how it play a role in homeostasis and why is transportation across the cell membrane (active, and passive) is important to maintaining homeostasis, and cellular activities.
Answer:
Explanation:
Cell transport refers to the movement of substances across the cell membrane. Probably the most important feature of a cell's phospholipid membranes is that they are selectively permeable. A membrane that is selectively permeable, or semipermeable, has control over what molecules or ions can enter or leave the cell, as shown in Figure below. This feature allows a cell to control the transport of materials, as dictated by the cell's function. The permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy.

Answer:
Yes, if you need any help ask :D
Explanation:
------> A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.

Estas de acuerdo con la aplicación del principio de la física en ecología:¨la energía no desaparece ni se destruye, solo se transforma de una forma en esta otra¨ argumenta tu respuesta
Answer:
Esta afirmación es correcta ya que la ley de conservación de la energía es también aplicable a sistemas vivos
Explanation:
La ley de la conservación de la energía (la cual es la primera ley de la termodinámica) indica que la energía no se puede crear ni se puede destruir, solamente se transforma, de un tipo a otro. La ley de la conservación de la energía es de vital importancia para entender la existencia del mundo natural. En ecología, la energía fluye de un nivel trófico a otro en forma de biomasa, es decir, dentro de la cadena alimentaria. Esta energía no se puede crear ni destruir sino que es almacenada en los organismos, los cuales representan sistemas abiertos que intercambian materia y energía con el medio. Una vez dentro del organismo, una parte de esta energía es transformada (en plantas, por ejemplo, la energía es convertida en enlaces químicos durante la síntesis de carbohidratos), mientras que otra parte de la energía se elimina al exterior (por ejemplo, se disipa en forma de calor), pero la energía no se crea ni se destruye.
