Answer:

Depend on how much water there is

Explanation:

Answer:

The lighter liquid floats on the heavier liquid, which sinks to the bottom. Water's density varies with temperature; when heated it will expand and therefore increase in volume. This means its mass per volume will decrease and it becomes less dense. Warm water, thus, is generally less dense than cold water.

Trees and other plants take up mineral and non-mineral nutrients from the soil through their roots. These nutrients are stored in the leaves, flowers and other parts of plants. The nutrients are either transferred to animals when animals eat the plants or they are transferred back into the soil.

No.

Explanation:

I think they are harmless.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:

Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.

You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.

Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.

Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.

These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Answer: San Andreas Fault

Explanation: took a test

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

QUESTION - 3 ---->   Revise & Repeat

A --->How did the  Gas Levels Change:

ANSWER ----> O2 = Went Lower, (Decreases)

ANSWER ----> CO2 = Went Higher (Increases)

B ---> The total of  O2 & CO2:

O2 =   5.0  

CO2 = 7.0

5.0 + 7.0 = 12

ANSWER ------>  So, Total Of  O2 & CO2  =  12

C ---->  Why do the gas levels stop changing in this case:

ANSWER ----> It is because there is no Exchange of Gases, However, the snails died and the gas levels did not change!

QUESTION - 4 ----> Challenge:

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Scientists are continuously studying data everywhere were if they were to be examining 2 million light-years away or something so discrete, you need a magnifying glass.  Scientists are always, measuring things qualitatively and that means by their quality and not the quantity and that is how most scientific questions are answered. Now if scientists studied by there quantity, which means to use for how much there is instead of how good something is built or studied or measured scientists data would be much different.

Answer:

Explanation:

Genetically engineered foods are inherently unstable. Each genetic insertion creates the added possibility that formerly nontoxic elements in the food could become toxic.

Genetic engineering can also alter the nutritional value of food.

Another hidden risk of GE foods is that they could make disease-causing bacteria resistant to current antibiotics, resulting in a significant increase in the spread of infections and diseases in the human population. 

Answer:

Many people believe that GMOs are bad for their health – even poisonous – and that they damage the environment.

Explanation:

Moreover, most GM crops are either bred to withstand chemical pesticides or developed to generate insecticides themselves. When herbicides are applied on resistant crops, the weeds acquire resistance over time, necessitating the use of even more chemicals. Crops genetically modified to generate pesticides, on the other hand, create poisons that are toxic not just to pests but also to other insects such as butterflies, moths, and insect pollinators.
