Answer: B. 5
Explanation:
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.
how are things transported through the membrane
Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.
Write any four effects of climate change.
Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

why were darker moths able to survive & white ones were not?
Answer:
with a record of 98% in 1895. The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. ... This selective survival was due to birds which easily caught dark moths on clean trees, and white moths on trees darkened with soot.
How are kinetic and potential energy are considered to be mechanical energy?
Answer:
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). ... A moving car possesses mechanical energy due to its motion (kinetic energy).
What is the Gestalt Principle?
Answer:
The Gestalt Principles are a set of laws arising from 1920s’ psychology, describing how humans typically see objects by grouping similar elements, recognizing patterns and simplifying complex images. Designers use these to engage users via powerful -yet natural- “tricks” of perspective and best practice design standards.

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.
Thus, option B is correct.

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.
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.
