What are keystone species ?The presence of the species whether plant or animal in an ecosystem largely influence on a given environment called as keystone species.
It affect the habitat of all living organisms, so that the ecosystem would become functionless in absence of keystone species.
On of the best example is prey-predator relationship.
Some important environmental influence of keystone species are, it affect organism's physical appearance.
There is an impact of parasites, diseases on prey and host population, act as a mutualist, absence of key stone species leads to domino effect.
For example in absence of carnivore, number of herbivores increased, hence the environment cannot support the infinite number of herbivore population.

What is the process of nitrification?
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Fungi convert nitrogen in dead plants into ammonium, which converts proteins into ammonia.
Nitrogen is converted into a useable form through lightning fixation.
Plant enzymes reduce nitrogen compounds into amino acids.
Answer:
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.

A taxon ending in ophyta:
O indicates the organism is a plant
O could be plant or animal
O represents a family
O is lower than a class
(NEEDS TO BE RIGHT)
(Will try and mark brainliest if correct)
Answer:
indicates organism is a plant
Explanation:
Honestly I had trouble figuring this one out, but this should be the answer if not then its definitely "could be a plant or an animal"
A taxon ending in -ophyta: indicates the organism is a plant. (Option A). The suffix "-ophyta" is commonly used in the naming of various plant divisions or phyla, such as "Bryophyta" (mosses), "Pteridophyta" (ferns), and "Chlorophyta" (green algae).
The classification of organisms involves grouping them into various taxonomic ranks based on their evolutionary relationships and shared characteristics. The suffix "-ophyta" is commonly used in botanical nomenclature to indicate a division or phylum of plant organisms. Each taxonomic rank represents a specific level of classification, from broader categories like kingdom and division to more specific categories like genus and species.
In the case of the suffix "-ophyta," it is used to name various groups of plant organisms. For example:
Bryophyta: This division includes non-vascular plants like mosses, liverworts, and hornworts. These plants do not have true roots, stems, or leaves and are often found in damp environments.Pteridophyta: This division includes vascular plants like ferns, horsetails, and club mosses. These plants have true roots, stems, and leaves and reproduce by spores.Chlorophyta: This division includes various green algae, which are photosynthetic aquatic organisms that are closely related to plants.By using the suffix "-ophyta" in the naming of these divisions, scientists indicate that these groups of organisms are indeed plants or plant-like in nature. This naming convention helps organize and classify the vast diversity of plant species based on their shared characteristics and evolutionary history.

An Allele is best described as:
A. A version of a gene
B. A recessive gene
C. A dominant phenotype
D. A test cross
An allele is best described as a version of a gene. Option A is correct answer.
Genes are segments of DNA that contain instructions for the development and functioning of living organisms. Each gene can exist in different forms, called alleles.
For example, let's consider a gene that determines eye color. This gene can have different alleles, such as brown allele, blue allele, and green allele. Each allele represents a different version or variant of the gene.
The different alleles of a gene can lead to variations in traits or characteristics. In the case of eye color, individuals with two copies of the brown allele will have brown eyes, individuals with two copies of the blue allele will have blue eyes, and individuals with one copy of the brown allele and one copy of the blue allele will have a mix of brown and blue eyes.
So, the correct answer is A. A version of a gene. An allele represents different versions of a gene that can result in variations in traits or characteristics.
Option A is correct answer

Behind your house, there's a gorgeous pond filled with frogs. You notice that the frogs behind Mr. Archer's house often have three legs. You start wondering if the fertilizer that Mr. Archer uses for his lawn is causing the deformities in the frogs. You collect 10 frogs and put the special fertilizer in their container (Group A). You put another 10 frogs and place them in a different container with just water (Group B). A week later, 7 out of 10 of the frogs in group A grew only three legs. The frogs in group B grew four legs.
What is the independent variable?
I need to write my hypothesis based on this question
Do plants need sunlight to grow
My independent variable is the amount of sunlight each plant gets
Dependant variable is the growth of the plant
Everything else are controlled same
Answer:
If a plant gets more sunlight, then it will grow more because sunlight is beneficial and necessary for plant growth.
Explanation:
*This is only one way to write the hypothesis if you believe something else will happen you should reword it. The hypothesis should be based on your own educated guess.
Hypotheses should be written in the if-then-because format. This means to begin your hypothesis with the word if and explain your independent variable. Next, use the word then and explain what you believe will happen. Finally, write because and explain why you believe this phenomenon will occur. Hypotheses do not need to be 100% correct; it is common for scientists to be incorrect before an experiment. Hypotheses are just guesses based on research. If you are incorrect at the end of an experiment, simply explain that and what actually happened in your conclusion.

Pump jacks use upward force and pressure to slowly move oil up a drill shaft. Which statement best describes an environmental consequence of this process?
O Soil is removed by the force and pressure of the drilling process.
High salinity of wastewater reduces soil fertility and growth of vegetation.
Wastewater is contaminated with oil and becomes sludge in landfills.
O Heavy metals are released into surrounding soil, poisoning local vegetation.
The main consequence of this process is that the soil is removed by the force and pressure of the drilling.
For the extraction of oil from the land, the vegetation is removed that destroys the habitat of many organisms as well as the degradation of soil occurs due to the force and pressure of the drilling machines.
In water, the aquatic organisms including plants and animals are adversely affected due to this process of extraction so we can learn that there are many consequences of extracting oil from the soil to the surrounding environment..

Sugars are particularly important fuel molecules, and they are oxidized in small steps to carbon dioxide and water.In this section we trace the major steps in the breakdown, or catabolism, of sugars and show how they produce ATP, NADH, and other activated carrier molecules in animal cells. We concentrate on glucose breakdown, since it dominates energy production in most animal cells. A very similar pathway also operates in plants, fungi, and many bacteria. Other molecules, such as fatty acids and proteins, can also serve as energy sources when they are funneled through appropriate enzymatic pathways.
