Answer:
Illumination results auxin moving to the dark side of stem tips. As this auxin diffuses down the dark side of the stem, the cells respond by enlarging. This causes the plant to bend toward the light.
what are the three molecular components of cellular membranes?
Answer:
Lipids (50%)
Proteins (50%)
Carbohydrate portions of glycolipids and glycoproteins (10%)
Explanation:
Hope this helps :)
There are basically three major classes of membrane lipid molecules, which are: phospholipids, cholesterol, and glycolipids.
What is cellular membrane?The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
Lipids (phospholipids and cholesterol), proteins, and carbohydrate groups attached to some of the lipids and proteins are the primary components of the plasma membrane.
Membrane lipid molecules are classified into three types: phospholipids, cholesterol, and glycolipids.
Glycerol is a three-carbon molecule that serves as the membrane lipids' backbone.
Thus, these are the three molecular components of cell membranes.

determines the symbiotic relation-
ship between a sloth, which is a
slow-moving mammal, and a species
of green algae that lives in the
sloth's fur.
Explanation: this experiment is long term which means patience is compulsory. you need to have a wild sloth and a domesticated sloth adopted right at their birth (he should be in a controlled environment that mimics the wild). your domesticated sloth shouldn't have the algae. at their middle age, you should compare them with them from every aspect.

a nucleus, the endoplasmic reticulum, and lysosomes.
b. nucleus, the endoplasmic reticulum, and chloroplasts.
c. nucleus and mitochondria.
d. endoplasmic reticulum and the Golgi apparatus.
Answer:
C
Explanation:
The nucleus contains most of the dna and the mitochondria contains a small amount
Mitochondria and nucleus are organelles that are surrounded by two membranes and contain DNA. Therefore, option (C) is correct.
What are cell organelles ?
Cell organelles are specialized structures who's function is to perform various jobs inside the cell. These can be found in either prokaryotic or eukaryotic cells.
Eukaryotes are two membrane bound structure i.e. have cell wall and cell membrane. They contain organelles who are also double membraned in nature for e.g. mitochondria and nucleus.
Apart from these mitochondria and nucleus can undergo DNA replication independently due to presence of DNA . Mitochondria generate most of the chemical energy required to power the cell's biochemical reactions. And nucleus contain genetic information along with instructions required for cellular processes.

Why do you think there are more organisms and energy available for life in the producer level?
Answer:
Producers which means plants have the most energy in a food chain or web besides the sun and they give an organism more energy than a primary consumer or secondary consumer would. Plants absorb about 1% of the sunlight that strikes them. The rest is reflected into space or transmitted through objects.

What drives surface currents?
differences in air temperature
differences in climate
differences in water density
differences in water salinity
Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

American apple cells contain an enzyme that turns the tissues brown when an apple is peeled and left for a time. Boiled apple does not go brown. Explain why the boiled apple behaves differently.
Answer:
I think I got it from recipetips.com
When cooking apples it is not as much of a concern because once they are cooked, the browning will stop. When fresh apples are peeled or cut open, the apple's cells are exposed and react with the oxygen in the air. The reaction that occurs, which is called oxidation, is what turns the apple brown.
Explanation:
Enzymes are proteins. As such they are very specific. When the apple is boiled, the enzyme becomes denatured and as such doesn't turn the apple brown.
