Explain why the cell membrane is the brain of the cell, as opposed to the nucleus.
Answer:
because it holds the information needed to conduct most of the cell's functions.
Cell membrane controls the transport of molecules across the cell and its external environment, Thus, it is called as the brain of the cell.
Why is cell membrane important?Cell membrane regulates most of the cellular activities through the property of selective permeability.
It is responsible for maintaining the cellular equilibrium through influx and efflux of ions and molecules.
There are various receptors present on the cell membrane which regulates the vital biochemical processes taking place in the body.
Cell membrane functions in the cell-cell recognition and cell signalling through various receptors.
Cell membrane is important in regulating body homeostasis. It offers the protective environment to the cell.
Control and regulation of activities is processed through brain.
Therefore, cell membrane is considered as the brain of the cell.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.
Answer:
13,636 seconds = 227.3 minutes = 3.79 hours
Explanation:
The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).

Explain how an abiotic factor (stronger storms, warmer oceans, or lower ocean pH) can affect populations in a coral reef ecosystem
Answer:
Climate change leads to: A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease.
Explanation:
Sea level rise: may lead to increases in sedimentation for reefs located near land-based sources of sediment. Sedimentation runoff can lead to the smothering of coral.

How does cooling of magma affect crystal size?
A) Slow cooling creates small crystals
B) Fast cooling creates both large and small crystals.
C) Slow cooling creates large crystals
D) Fast cooling create large crystals
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Answer:
I learned about this, Uhm...
C is the right answer bc igneous rocks cool and form crystals.
Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.
Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

Ocean currents store energy and help to distribute heat and
Answer:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

How are the smallest ocean waves produced?
Answer:
Ocean waves are usually formed by a distant wind. ... The area which the wind affects the surface is called the fetch. The larger the fetch, the greater the waves produced. the small waves generated by storm winds are often confused and disorganized.
Explanation:
Answer:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

C all cells come from other cells
D all living things are made of cells
Answer:
A
Explanation:
Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.
which of the following does not affect the rate of photosynthesis a) temperature b) light intensity c) soil d ) water intake
Answer:
a) temperature
Explanation:
took test and got right
light intensity does not affect the rate of photosynthesis .
what is photosynthesis ?The process in which plants, algae and certain bacteria use light energy of sunlight, water, carbon dioxide and convert light them into chemical energy and starch. called as photosynthesis.
Photosynthesis occur in special organelles named chloroplast which has its own DNA, genes and hence can synthesize their own proteins.
Chloroplasts have stroma, fluid, and stack of thylakoids known as grana, three types of chlorophyll such as chlorophyll a, chlorophyll b, and carotenoids.
Oxygenic photosynthesis is commonly observed in plants, algae and cyanobacteria where electrons are transferred from water to carbon dioxide by using light energy, to produce energy, oxygen is produced along with carbohydrates.
