Answer:

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water

Explanation:

please give brainliest

Answer:

Water covers about 71% of the earth's surface.

326 million cubic miles of water on the planet

97% of the earth's water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling).

320 million cubic miles of water in the oceans

3% of the earth's water is fresh.

2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.

0.5% of the earth's water is available fresh water.

If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon).

In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.

This supply is continually collected, purified, and distributed in the natural hydrologic (water) cycle.

Answer:

A

Explanation:

Deforestation is the cutting of trees. Trees like plants use photosynthesis for energy. Products of photosynthesis include carbon dioxide. When carbon dioxide is made the tree does not release it but when trees are cut down where does all of that carbon dioxide go? It gets released in to the atmosphere therefore the answer is A.

Answer:

Can be negative, neutral or positive change.

Explanation:

A negative change can result in diseases such as sickle cell anemia. This is because the amino acid that codon will code for changes.

A neutral change can result if the codon codes for the same amino acid as the original one.

A positive change can result if the new codon can express a beneficial phenotipic change. Something like having the body surviving on decreased amount of water or increased amounts of sodium is beneficial for organisms living near the equator.

Answer:

As context, there are two sides of a mountain range:

A) The windward side

B) The leeward side

As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.

In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.

This is why you see mountain ranges near deserts.

Answer:Extracting fossil fuels. There are two main methods for removing fossil fuels from the ground: mining and drilling. Mining is used to extract solid fossil fuels, such as coal, by digging, scraping, or otherwise exposing buried resources.

Explanation:

Answer:

Both have different gene expression due to produce from different sources.

Explanation:

Gene expression is different between human fibroblasts and induced pluripotent stem cells because both cells are formed from different sources. Human fibroblasts is produced from ''mesenchyme'' a type of connective tissue whereas induced pluripotent are the stem cells which can be produced from adult cells so we can say that both have different gene expression.

Both have different gene expression due to produce from different sources.

Answer:

The climate zone that Margo identified belongs to the Tropical zone

Explanation:

There are three specific types of climate zones. From the equator to the poles, we can find the tropical zone, the temperate zone, and the polar zone.

The tropical zone spans from 0º (Equator) to approximately 23.5º latitude to each hemisphere, limited by Cancer and Capricorn tropics. This strip includes the area that Margo pointed in orange.

Tropical zones characterize by having humid and warm weather most of the year, the medium temperature that ranges 18-30ºC, abundant precipitation, variable dry seasons, perennial and evergreen vegetation near the equator, and decidual vegetation farther the equator, species richness. These are general characteristics that might vary depending on the region.

PROTIST, FUNGI, PLANTS

Explanation:

The Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi. Characteristics of Protists: mostly unicellular, few multicellular, eukaryotic, can be heterotrophic or autotrophic. Ex: algae, Paramecium, kelp (multicellular).

The three types of organism that would be classified as eukaryotic multicellular and heterotroic should be protist, fungi, and plants.

It should treated as the unicellular organisms that contains the attributes,  similar kind of the plants, animals, or fungi.

The attribute of protists involved the unicellular, less multicellular, eukaryotic, heterotrophic or even autotrophic.

These organisms are classified together since they are made up of eukaryotic cells.

Therefore, the above should be considered as the protist, fungi, and plants.

C. The distribution of alleles does not change from one generation to the next.

Answer:

C

Explanation:

Minerals, fresh water, and biosphere resources are distributed unevenly around the planet as a result of past geologic processes. ... Mineral, fresh water, ocean, biosphere, and atmosphere resources are limited, and many are not renewable or replaceable over human lifetimes.

The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.

Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.

Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.

Explanation: Im just that smart

Hummingbird responds to winter with migration, whereas Chipmunks responds to winter with hibernation.

Hibernation is the state that occurs in animals in which they enter a deep sleep in order to endure the freezing winter months and the lack of food. For example, Polar beer loses its activity throughout the cold months. The movement of birds from one location to another, either in search of food or as a response to changes in the weather, is referred to as migration.

When an animal is unable to migrate, it will either hibernate or employ some other method in order to secure food and shelter for itself. The state of hibernation is analogous to that of an extremely deep slumber. The animal's body temperature will begin to drop, and it will also experience a slowdown in both its heart rate and its breathing rate. This assists the animal in conserving its energy so that it can endure the winter.

Biotic and abiotic factors interact with each other to form the ecosystem. Abiotic factors are the non-living things whereas biotic factors are the living things.

An ecosystem is made up of biotic and abiotic factors which interact with each other. Biotic factors include those organisms or things which are living and belong to a trophic level in a food cycle. The abiotic factors are those which are non-living but affect the survival of the biotic factors of the ecosystem.

Abiotic factors includes clock, water, paper, glass, aluminum, wooden ruler, sand, clouds, corpse, steak, pork chops, salad, bread, pipe, cotton fabric, wool, gold, plastic, grapes, air, etc.

Answer and Explanation:

The answer is A. These are examples of competition because the organisms are fighting for resources.

This is because both pairs of species are fighting for the same thing in order to live.

It is NOT:

B. because the passage was NOT saying that woodpeckers and squirrels are eaten by lions and cheetahs. They mention both of them, but they are mentioning the competition that each pair face.

C. Predation isn't taking each other's foods and homes, it is eating one another, and that isn't what is happening in the given situations.

D. This is incorrect because the species that doesn't get what they need are harmed because they don't have shelter or food to live, while the other helps itself to the food/shelter.
