Explanation:
Nitrate deficiency
Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
The leafes turns pale yellow when plants have lack of nitrate ions in the plants.
How nitrate defeciency occur in plants?Excessive irrigation and heavy rains cause nitrogen deficiency due to overwatering. A lack of soil moisture tampers with the absorption of water-soluble nutrients by plant roots.
Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant's ability to photosynthesis and grow properly.

Brain-List?
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.

I believe the answer is A.
Natural selection causes mutations
True or false
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
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. This system of classification allows scientists to understand the relationships and diversity of life on Earth.

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.
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.
