Which is a function of the cell membrane?
Performs photosynthesis
Controls what enters and leaves the cell
Produces proteins
Provides energy to the cell
Answer: I believe it is B.
Explanation:
The cell membrane protects the cell's interior, provides support and maintains the cell's shape. It also controls what enters and leaves the cell. I hope this helps!! :)
The cell membrane separates the intracellular space from the extracellular space. It controls what enters and leaves the cell. The correct answer is option B.
The term "plasma membrane" also refers to the cell membrane. It is the cell's outermost layer in animals. It is a membrane made of lipids and proteins that is semi-permeable. Between the outside environment and living systems, there is a plasma membrane. The plasma membrane regulates the movement of solutes and solvents between the cell and its surroundings. A plasma membrane's permeability properties include semi-permeability, impermeability, permeability, and selective permeability.
Therefore, the main function of the cell membrane is to control the entry and exit of materials in the cell. The correct answer is option B.

indicate structural adaptations of Mitochondria for its function
Mitochondria(Mt) are the cell's "power stations" because the energy currency for the metabolic processes in the cell is synthesised inside this organelle via aerobic respiration. This process is known as oxidative phosphorylation. Mt is a double membraned, semi-autonomous organelle.
The mitochondrion's structure is specially tailored to the function it performs:
The outer membrane contains carrier proteins that allow pyruvate produced during glycolysis to be transported from the cytoplasm.The electron transport chain(a series of protein complexes) and ATP synthase are located in the inner membrane to transfer electrons and ATP production respectively.The inner membrane is folded into numerous pockets called cristae, which raises the surface area: volume ratio.When proton accumulation occurs, the small intermembrane space between two membranes increases the hydrogen gradient.Matrix is the core chamber containing the necessary enzymes and pH for the Krebs cycle(oxidation of acetyl-CoA derived from pyruvate) to take place.To learn more, refer:

The mechanisms by which restrictive lung diseases reduce lung function is increasing shortness of breath, chronic cough, weight loss, and fatigue.
How does the breathing process work?
Pulmonary ventilation consists of the flow of air into and out of the lungs with each cycle, which is composed of inspiration and expiration; it is a what they run on is the process of running the resources.
The respiratory pattern of individuals with restrictive diseases is a higher respiratory rate and lower tidal volume. of the airways, that is, they have a smaller radius. The faster the flow, the greater the friction of the molecules with the airways, further increasing the resistance.

Explain how a species can evolve through natural selection. What is natural selection in your own words?
Answer:
Natural selection is process that allow organism that has suitable attributes with its environment, to thrive (grow in population), to survive, and to pass its genetic information to the next generation (children, grand children).
Explanation:
For example: in an island, a male giraffe, and a female giraffe produce giraffe children with various attributes. Some giraffe children have short neck, and some have long neck.
Giraffe eats the leaves of Acacia tree, and Mimosa tree. Many acacia tree and tall mimosa tree in that island, are tall trees, so a giraffe that has long neck can reach that tall tree, eat the leaves, survive, and grow to adult stage.
A giraffe that has short neck, can only eat small quantity of leaves, then it suffers, can not grow, becomes skinny, and unable to compete with other giraffe finding its mate. It can't pass its genetic information to the next generation, and becomes extinct.
That's how natural selection, in above case, an island with a lot of tall acacia trees and mimosa trees selects giraffe with long neck to survive.
The next interesting follow up question would be how a male giraffe and a female giraffe produce various kind of giraffe children? The answer is a pair of chromosome become a single chromosome in giraffe sperm, and in a giraffe eggs. But that question and its answer are beyond the scope of the original question.

Choose TWO locations below (A, B, C) and provide a two-sentence weather forecast for that location. Your forecast must include Wind direction, general wind speed (high, moderate, low) general temperatures (cold, cool, mild, warm, hot), and sky conditions(precipitation/stormy, sunny cloudy).
Climatic maps use isobars to read the barometric pressure and to determine climatic patterns in different areas. Points B and C are described below.
How to interpret a weather map?
Meteorology is determined mainly by barometric pressure, which is the pressure exerted by atmospheric air on the Earth's surface. It is measured in millibars, Mb.
Barometric pressure systems are closely associated with weather patterns, which is why it is used to create climatic maps.
⇒ Pressure:
An average pressure system at sea level ⇒ 1013 Mb.A high-pressure system ⇒ air descends ⇒ Good weather and few clouds ⇒ 1030 Mb.A low-pressure system ⇒ air ascends ⇒ Hot ascending air condense and forms clouds. Bad weather, storm probabilities ⇒ 1000 Mb.⇒ Isobars:
Used to read barometric pressures in climatic mapsThese are curve lines that indicate the areas with the same barometric pressures.They are arranged in concentric figures, one inside the other one. The smallest one indicates the pressure center.- High-pressure center is indicated with an H
- Low-pressure center is indicated with an L
Isobars are significant when determining wind speed and direction.
⇒ Wind direction:
In High-pressure center is indicated with clockwise arrows in the northern hemisphere
In Low-pressure center is indicated with counterclockwise arrows in the northern hemisphere
Winds tend to move from high pressure areas to low pressure areas.
⇒ Wind speed:
The closer isobars are between each other, the stronger and faster the wind is.
⇒ Front types:
Cold front ⇒ represented by blue lines with blue triangles pointing in the direction of the front movement. When a cold front passes by, there are high probabilities of strong winds and severe precipitations. Hot front ⇒ represented by red lines with red semi-circles pointing in the direction of the front movement. There is an increase in temperature as the front approximates. There might be precipitations. Occluded front ⇒ represented by purple lines with red semi-circles and blue triangles pointing in the direction of the front movement. It forms when a cold front overtakes a warm front. There might be storms.
Point C
Near a Low Pressure system Isobars: close to each otherMass of light, warm and wet air. Since the air is light, it tends to ascend, creating clouds and rains.Air pressure: low -around 1000 Mb-Weather conditions: cloudy, rainy, stormy.Wind direction: counterclockwise in the northern hemisphere.Wind speed: high to moderateTemperature: warm or hotA hot front is approximatingPoint B
Probably near a High Pressure system Isobars: separated from each otherMass of dense, cold/cool and dry air. Since the air is dense it tends to descend.Air pressure: high - around 1030 Mb-Weather conditions: clear, cloudlessWind direction: clockwise in the northern hemisphere.Wind speed: moderate to lowTemperature: cold or coolA cold front has passedYou can learn more about weather maps at

What can be concluded from the fossils of various organisms is that the organisms evolved to adapt to the environmental conditions of their contexts. Additionally, its morphology changed radically.
What is a fossil?Fossils is a term to refer to the remains of past organisms preserved in sedimentary rocks. The science that deals with the study of fossils is paleontology.
Within paleontology are paleobiology, which studies the organisms of the past (paleobiological entities, which we know only from their fossil remains).
This science is the one that can study fossils in detail and draw conclusions such as the shape of organisms changing as a way of adapting to the environment in which they lived.
