Help MEEEE PLEASEE........​

Answer: One major clue is that we humans are, quite simply, stronger than we realise. Our movements are controlled by the contraction of muscles through signals relayed by nerves. When going about our daily lives, our bodies tend to use whatever the least amount is of muscle-and-nerve "motor units" to perform an action.

Hope this helps... Stay safe and have a great day/night!!! :D

Answer:

it is necessary for cells to remain small in size because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients and exchanging materials between the inside and outside of cells.

Cells are small so they can have an efficient surface area to volume ratio. This is going to allow the cell to easily excrete waste product.

That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is.

Answer:

Granites and rhyolites consist predominantly of quartz and potash feldspar; gabbros and basalts, predominantly of pyroxene and plagioclase feldspar. Other rock types have intermediate mineral compositions.

Explanation:

It is made up of sodium feldspar, potassium feldspar, and coarse quartz grains (10–50%). More than 80% of the rock is composed of these minerals.

Granite is a pale-colored plutonic rock that is mostly found in mountainous regions of the continental crust.

Quartz and potash feldspar make up the majority of granites and rhyolites, whereas pyroxene and plagioclase feldspar make up the majority of gabbros and basalts. Other types of rocks contain mineral compositions that are in between.

Magma, which is a molten substance that flows and hardens underground while slowly cooling, is the source of intrusive rocks.

Therefore, the majority of the continental crust is composed of granite, the most common kind of igneous rock, intrusive igneous rock is granite.

Answer:

The H.M.S. Challenger embarked from Portsmouth, England on December 21, 1872 and changed the course of scientific history. Physicists, chemists, and biologists collaborated with expert navigators to map the sea. This interdisciplinary spirit has continued to the present day. During the 4 year journey, the voyages circumnavigated the globe, sounded the ocean bottom to a depth of 26,850 feet, found many new species, and provided collections for scores of biologists.

C. Wyville Thomson led the expedition but died of exhaustion from the journey, which ended on May 24, 1876. The Challenger had zig-zagged around the globe and had visited every continent, including Antarctica.

The reports of the Challenger expedition were supervised by Sir John Murray, whose biological conclusions were of great importance to the later development of marine biology. He concluded, for example, that the deep-sea fauna was not "ancient," in that it did not resemble the faunas found in ancient fossil deposits.

The H.M.S. Challenger changed the course of scientific history. The expeditions circumnavigated the world, sounded the ocean floor to a depth of 26,850 feet. Itdiscovered numerous new species, and supplied collections for hundreds of researchers over their four-year adventure. The Challenger was a corvette, a military ship that went by sail but had auxiliary steam power to help steady the ship during sampling. The expedition was commanded by C. Wyville Thomson, who died of fatigue on May 24, 1876, at the end of the voyage. The Challenger has zig-zagged its way around the world, stopping at every continent except Antarctica. Sir John Murray oversaw the Challenger expedition's reports, and his biological results were crucial to the eventual development of marine biology. For example, he decided that the deep-sea fauna was not "old" since it did not reflect faunas found in ancient fossil beds.

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, there is a distinct relationship between the endoplasmic reticulum and the plasma membrane. The endoplasmic reticulum are responsible for protein synthesis which are used by the remaining organelles (including the membrane) to function. The endoplasmic reticulum is also involved in lipid synthesis and has a network of tubules (which are used for carrying materials throughout the cell) that can deliver lipids into the cell membrane. These lipids are responsible for the semi-permeability function of the cell/plasma membrane.

climate, salt water, tidal fluctuation and soil type

Explanation:

Climate, salt water, tidal fluctuation and soil type are the limiting factors for the mangrove wetland community. mangrove plants only present on wetland regions where the climate is humid. It also grow on the land where saline soil is found but excess saline conditions reduces its normal growth and development. For better growth of mangrove plants, soils made up of sand, silt and clay which are rich in organic matter.

Complete dominance occurs when the dominant allele completely masks the recessive allele in heter0zyg0us individuals. 1) 100% / 2) no chance / 3) 50% / 4) no chance / 5) 1:2:1.

------------------------------------------------------------

Available data:

→ Six diallelic genes code for six different traits.

→ All genes express complete dominance, meaning that the dominant allele hides the expression of the recessive one.

→ Beyonce ⇒ ee ww Dd Hh cc Bb

→ Bruno Mars ⇒ ee ww dd Hh CC Bb

→ Cross:  Beyonce x Bruno Mars

Answer:

C. Most mammals are secondary consumers. Most invertebrates are primary consumers.

Explanation:

Net production efficiency (NPE) refers to how efficient an organism at one trophic level is in utilizing and transferring energy to the next trophic level. Consumer organisms obtain energy (from biomass) when they feed on other organisms. They then use this energy for their metabolic activities and transfer the rest when eaten or fed on.

The net production efficiency decreases with increasing trophic level because higher organisms use more energy than lower ones. In this case, invertebrates use energy they obtained lesser or more efficiently than mammals, hence, making them have a HIGHER net production efficiency than mammals. Therefore, invertebrates are mostly primary consumers and utilize energy lesser than mammals which are mostly SECONDARY CONSUMERS.

A population is a number of organisms of the same species living together in an area at the same time.

A community is an interacting group of various species in a common location. The common location here is a pond.

A food chain shows the flow of energy and material being transferred from one organism to the next. The example given could be a food chain, but what disqualifies it from being a food chain is the perch it does not provide energy to any of the organisms listed in your example.

OH LOL I DID THIS IN 7TH GRADE

Explanation:

so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived

MY SENTENCE

It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.

Answer:

The endocrine system is responsible for being the chemical messenger of the body and controlling metabolism and respiration.

Answer:

Increases reaction rate by lowring its activation energy.

Explanation:

i.e If the chemical reaction completes in 5 hours it means that reaction's activation energy is very high.This factor causes decrease in rate of reaction so to increase reaction rate and to decrease activation energy enzymes or catalyst are added so now reaction will be completed in half hour.This is the importance of enzymes/catalysts.Enzyme and catalyst cann't start reaction but they increase rate of reaction and decrease time to reach equillibrium.
