How is average global temperature calculated?

Answers

Answer 1

Answer:

GISTEMP uses air temperature recorded with thermometers slightly above the ground or sea, while AIRS uses infrared sensing to measure the temperature right at the Earth's surface (or “skin temperature”) from space.

In a food chain that includes, in order, plants, markhors, and snow leopards, the role of markhors is to eat the plants. Thus, the correct option is A.

What is a food chain?

A food chain is the linear network of how energy and other nutrients move through an ecosystem. At the very basic level, there are plants which produce energy, then it moves up to higher-level organisms like the herbivores. After that, when carnivores eat the herbivores, energy is further transferred from one to the other higher carnivore and finally to the decomposers.

Markhors are the organisms which eat plants. The plants produce their own energy through the sun. These markhors are eaten by the snow leopards. Markhors are large grazer species that eat a wide variety of grasses and other plant species. They also serve as prey species which is a source of energy for the large predators, such as the snow leopard.

Therefore, the correct option is A.

Natural selection causes mutations
True or false

Answers

False because it’s natural meaning from the outside. Hope this helped

The statement 'natural selection causes mutations' is FALSE.

Natural selection, also called survival of the fittest, is the main mechanism by which evolution acts.

Naural selection refers to the mechanism of differential survival and reproduction of individuals better adapted to the environment in which they live.

Mutations, i.e., alterations in the nucleotide (DNA) sequence of an organism, provide the raw material to generate genetic variability (diversity), which is a prerequisite for evolution to occur.

Populations and species evolve (change) by accumulating beneficial mutations that occur over time.

In conclusion, the statement 'natural selection causes mutations' is FALSE.

description of shrubland biome​

Answers

Answer:

The shrubland is a biome dominated by shrubs, with distinct seasons where one tends to be longer and drier while the other one tends to be shorter and wetter.

Explanation:

The shrubland is a biome that is mostly found as a transitional biome between the tropical and temperate biomes. This biome has a clear distinction between seasons. The summers are very hot and dry, experiencing prolonged drought, while the winters are mild to cool, and it is when most of the precipitation falls. This biome is exclusively terrestrial, thus it can only be found on land.

The landscape is dominated by shrubs. The shrubs tend to have needles and sharp leaves, and they are very well adapted to withstand high temperatures and prolonged drought. The animals too are well adapted to survive in dry conditions. Because this biome is suspectable to wildfires, the vast majorty of the animals use be it because of the manner in which they live or as a shelter.

What are taxonomic levels?

Taxonomic levels are a hierarchical system of classification used to categorize and study the diversity of life based on shared characteristics and evolutionary history.

The taxonomic levels, in order from the most specific to the most general, are species, genus, family, order, class, phylum, kingdom, and domain. Each level represents a group of organisms that share a certain set of characteristics and a common ancestry.

Which of the following statements is NOT true of photosynthesis?
Photosynthesis stores the energy from the Sun in molecules of sugar.
Photosynthesis captures and stores energy from the Sun.
Photosynthesis requires carbon dioxide and water.
Photosynthesis captures and uses energy from the Sun for daily activities.

Answers

Answer:

A

Explanation:

The statement 'photosynthesis requires carbon dioxide and water' IS NOT true.

Photosynthesis is a series of reactions by which plants and algae can produce sugars  (e.g., glucose) by using the energy from the sun, oxygen and water.

The photosynthetic reactions release carbon dioxide (CO2) as a byproduct, thereby CO2 is a product instead of a reactant.

Photosynthesis has two main types of reactions: light-dependent reactions and light-independent reactions (i.e., the Calvin cycle).

In conclusion, the statement 'photosynthesis requires carbon dioxide and water' IS NOT true.

Answer:

Explanation:

Xylem is a vascular plants tube-like structures that move water.

What are the functions of xylem?

Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage.

The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem consists of dead cells. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube.

Xylem cells constitute the major part of a mature woody stem or root. They are stacked end to end in the center of the plant, forming a vertical column that conducts water and minerals absorbed by the roots upward through the stem to the leaves.

Evolution occurs when there is selection pressure for some heritable trait over a period of time.

True
False

Answers

Answer:

True

Explanation

Everything is always evolving over an amount of time, for example say we had two types of rabbits, one had white fur and the other has brown. If the one that has white fur tries to live in the same habitat as the one with brown fur they will be able to be spotted easier. So the brown rabbits they have the “desirable trait” or “heretable trait” because they can hide from being hunted. Even then the brown rabbit will adapt over time, evolution is always competing, so if the brown rabbit needs to hop higher then over time the rabbits that have the strongest trait will become the new normal.
