How can some large molecules and charged ions get through the cell membrane?
Answer:
In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion.
Some large molecules and charged ions get through the cell membrane as
a result of osmosis, diffusion, facilitated diffusion etc.
Molecules get through the cell membrane through diffusion which is the
movement of substances from a region of higher concentration to a region
of lower concentration.
Facilitated diffusion is the same with diffusion but it makes use of a
substance for transport.

Answer:
I think its C... they change the speed.
Explanation:
"Enzymes are catalyst that speeds up the rate of biochemical reaction in living organism. They are protein in nature and they are involved in every process that take place in living organisms such as breaking down of food to building up of protein. In living organism, enzymes speed up the rate of chemical reaction by lowering the activation energy thereby bringing the reactants close to each other and weaken there chemical bonds which will enable the reactions to be faster".

identify the landmark that is not part of the sphenoid bone.
The landmark that is not part of the sphenoid bone is Olfactory foramina
Sphenoid bone is are bone that can be found at the central of the human skull and they are made up of cranial bones which are bones that help to protect the human brain from injury.
Olfactory foramina is not part of sphenoid bone because they are hollow space that is found in the cribriform plate.
This hollow space made it possible for the sensory nerves to pass through the human nasal cavity which in turn help to transport information from the olfactory receptors to the brain.
Inconclusion the landmark that is not part of the sphenoid bone is Olfactory foramina.

Observe: The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis?
Form hypothesis: Which color of light do you think will maximize the rate of photosynthesis?
Gather data: Set the Light wavelength to 400 nm. (The symbol “nm” stands for nanometers. A nanometer is a billionth of a meter.) Visible light ranges from 400 to 700 nm.
On the TABLE tab, click Record data. Then set the Light wavelength to 420 nm, and repeat. Continue recording data in the Gizmo every 20 nm until the wavelength is 700 nm.
Which colors were absorbed best by the plant?
Which colors were absorbed the worst?
If tested throughout an experiment, one would come to find that the color of light does in fact affect the rate at which photosynthesis takes place, with red and blue light being the most effective at promoting photosynthesis.
Photosynthesis is a series of chemical reactions performed by plants in order to transform light energy, in most cases being light from the sun, into molecular energy in the form of ATP molecules. Experiments have shown that the color of light to which plants are exposed can have positive or negative effects on photosynthesis rates depending on the color used.
Plants appear green to us due to the fact that they absorb all frequencies of light except green light, which is reflected. This reflection of green light serves to explain why plants show the lowest rates of photosynthesis when exposed to green-colored light. At the same time, the highest rates are when exposed to high-frequency blue or red spectrum light.

What is excretion and egestion
Answer:
Explanation: Excretion and Egestion Difference
Excretion is the process where an organism excretes the byproduct of a metabolic process using the different cellular and organ functions. Egestion, on the other hand, is the term associated with the excretion or elimination of undigested food from the digestive system of an animal.
Answer:
Basically egestion is when undigested food becomes waste and comes of out the body through the anus, and excretion is when your body removes toxic and waste material and excess products from organisms.

Think back to the three models of matter in parts A and B. Which model had a definite shape? Explain.
Answer:
C
Explanation:
Its C bc when the atoms are squished together they became a solid so. They become a shape aka definite shape. not like the first pic that a gas because there more room for them can move. Sec pic is a liquid because there's movement but they cant hold like a solid. And the third pic is a solid bc they are smashed together making they hard and giving them the shape.

Which characteristic explains why algae blooms are more likely to grow out of control in lentic ecosystems instead of lotic ecosystems?
O Photosynthetic organisms can grow undisturbed in sunlit, nutrient-rich lentic ecosystems.
O More photosynthetic organisms are found in lentic ecosystems than in lotic ecosystems.
O Lotic ecosystems have lower nutrient and dissolved oxygen levels than lentic ecosystems.
O Lentic ecosystems have higher turbidity, which is preferred by photosynthetic organisms.
Given the characteristics of lentic ecosystems, we can conclude that algae blooms are more likely to grow out of control because photosynthetic organisms can grow undisturbed in sunlit, nutrient-rich lentic ecosystems.
Lentic ecosystems are those whose water is still. This kind of ecosystem includes bodies of water such as:
LakesPondsReservoirs SeepsPoolsand so on. These can be temporary or permanent and are found in a wide range of sizes.
Lentic ecosystems minimize the mixing of the water, allowing the water to absorb more sunlight and become warmer. Warmer water allows organisms such as algae to move easier, allowing them to float to the surface quicker and absorb more sunlight. This creates a chain reaction given that the sunlight absorbed by the algae heat the water even more, thus promoting more algae growth. For these reasons option one is correct.

why is radiation a unique form of thermal energy transfer?
Answer:
The radiation occurs at all temperatures, with the rate of emission increasing with the temperature. Figure 3.1. Heat transfer by thermal radiation between two bodies. Unlike conduction and convection, heat transfer by thermal radiation does not necessarily need a material medium for the energy transfer.
Explanation:
none
Radiation is the electromagnetic transfer of heat energy through space. The majority of the electromagnetic radiation emitted by the sun is invisible to the human eye.
What is radiation?Radiation is energy that travels through space at the speed of light from a source.
This energy is associated with an electric and magnetic field, and it has wave-like properties. Radiation is also known as "electromagnetic waves."
Radiation is a mutagen that can eventually cause cancer. Radiation can either kill cells or damage their DNA, impairing their ability to reproduce and eventually leading to cancer.
High energy particles pass through your body when radiation is present.
Because radiation (primarily electromagnetic waves) can transfer energy even through a vacuum, no mas is required.
Other types of energy transfer involve the transmission of vibrational motion from one matter molecule to the next.
Thus, radiation is a unique form of thermal energy transfer.

Explanation:
The most important difference between primary cells and secondary cells is Select only the best answer: primary cells exhibit a reduction in potential as they run down secondary cells have more than two working electrodes only primary cells have a salt bridge secondary cells are rechargeable primary cells use chemical energy directly, while secondary cells convert energy to work before producing electricity
Hi there! This question is a bit confusing.
Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge.
Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.
Your answer would be "Secondary cells are rechargable"
