The practice that does the most to decrease the amount of water needed to farm is (A) drip irrigation.

Drip irrigation is a type of irrigation system that delivers water directly to the roots of plants, drop by drop, through a network of tubes and emitters.

This system uses water much more efficiently than traditional methods of irrigation, such as flood irrigation or sprinkler systems, because it delivers water precisely where it is needed and minimizes evaporation and runoff.

Crop rotation, cash crops, and no-till farming are also practices that can help to conserve water in agriculture, but they do not have as significant an impact on water use as drip irrigation.

Crop rotation involves planting different crops in a specific sequence to help maintain soil health and fertility, while cash crops are crops that are grown primarily for sale rather than for subsistence. No-till farming involves leaving the soil undisturbed between crops to help reduce erosion and conserve soil moisture.

Overall, while each of these practices can contribute to water conservation in agriculture, drip irrigation is the most effective in reducing the amount of water needed to farm.

Answer:

The answer is....

Explanation:

An organism's habitat and ability to reproduce determine its niche.

An organism's niche is determined by several factors, primarily its competition for resources, the features of its physical and geographic environment, and its unique nutritional and reproductive strategies.

An organism's niche in an ecosystem is determined by several factors tied to both its unique characteristics and the properties of the environment. These factors range from the resources it consumes, to its interactions with other species, to the physical features of its habitat.

Firstly, competition for resources such as food, water, sunlight, and mineral nutrients plays a significant role in determining an organism's niche, due to the restrictions imposed by the principle of Competitive Exclusion. This principle asserts that two species cannot occupy the same niche in a habitat, implying that they can't compete for all the same resources and still coexist in the same community.

Moreover, the components of an organism's physical and geographic environment, such as the habitat's climate, topography, and available species, are also essential determinants of its niche. This is because they significantly impact which organisms can exist within a specific area.

Lastly, an organism's nutritional and reproductive strategies add to the determination of its niche. These strategies depend upon the type of organism, its nutritional requirements, and the type of habitat it inhabits.

Answer: dna transcripted into rna

Explanation: dna is double stranded and rna in single and transcribed has to do with rna while translated is with ribosomes

This process is called transcription and it involves the conversion of DNA into RNA using the enzyme RNA polymerase. Transcription happens in three steps: initiation, elongation, and termination.

The process mentioned in the question, where a double-stranded molecule of nucleic acid gives rise to a single-stranded molecule of nucleic acid, is best described as: DNA is transcribed into RNA. In this biological process, known as transcription, the DNA serves as the template for synthesizing RNA. This happens in three steps: initiation, elongation, and termination. During initiation, the enzyme RNA polymerase binds to the DNA strand. In elongation, RNA polymerase moves along the DNA template strand, building the RNA molecule. Finally, in termination, the RNA polymerase reaches a sequence of DNA called the termination sequence, signaling the end of RNA synthesis.

Explanation:

A cell is the basic unit of life. However, there are many different types of specialized cells. This means they are modified by size, shape, or function according to their purpose. Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up our bodies.

Answer:

The correct answer will be- myofilamants-actin and myosin.

Explanation:

The skeletal muscle is made up of the muscle fibers which are cylindrical cells enclosed by layers. The muscle cell is divided into smaller units, the smallest of which is myofilaments.

The myofilaments are composed of the thin filaments called actin and thick filaments called myosin which together forms the functional unit of a muscle known as the sarcomere. The muscle contraction takes place due to the sliding of these actin and myosin over each other as a result of the signals arrived from the CNS.

Thus, myofilaments-actin and myosin is the correct answer.

Answer:

The correct answer is CLEAR CUTTING THE RAIN FOREST

Explanation:

The factors that affect the survival of living organisms can be divided into two major groups, which are density dependent and density independent factors. Density dependent factors refers to those factors that their impacts depend on the size of the population. Example of such factors are food availability, predation, migration and diseases.

Density independent factors on the other hand refers to those factors that affect population size regardless of their sizes. Examples of such factors are temperature, natural disasters, human activities, etc.

In the question given here, the clear cutting of the rain forest is brought about by human activity and is an example of density independent factor.

The answer is A. Clear cutting the rain forest because it is a human activity and that does not depend on the population size of a place.

Methamphetamine use can increase blood pressure and pose risks to the cardiovascular system. It can also lead to addiction, psychosis, and changes in brain structure and function.

Explanation:

Methamphetamine use poses several risks to the health of an individual. One of the risks associated with taking this drug is an increase in blood pressure. Methamphetamine is a stimulant that can cause vasoconstriction, which narrows the blood vessels and leads to an increase in blood pressure. This can put strain on the cardiovascular system and increase the risk of heart-related issues, including stroke. It is important to note that methamphetamine use can also lead to other adverse effects such as addiction, psychosis, and changes in brain structure and function.

The location of the fossil in Earth's layers helps scientists determine the order in which a species evolved.

The correct answer is Location of the fossil in Earth's layers. The study of fossils and their position in the rock layers, known as stratigraphy, can help scientists determine the relative age of different fossils and the order in which species evolved. By examining the layers of rock, scientists can identify the sequence of fossil species, with older fossils found in lower layers and more recent fossils found in higher layers.

The option that best helps scientists determine the order in which a species evolved is the location of the fossil in Earth's layers. This method is central to the field of stratigraphy, which studies the layers of sedimentary rock to establish a timeline for events. The principle of superposition is key in this field; it states that in undisturbed layers of rock, the oldest layers are at the bottom, and each subsequent layer is younger than the one beneath it. So, fossils found in deeper layers are typically older than those found in layers closer to the surface.

Explanation:

The number of bacteria in an experiment can be represented by an exponential function

[tex]f(x)=4^x[/tex]

where, x represents the number of hours.

We need to find the value of x when f(x)=64.

Substitute f(x)=64 in the given function.

[tex]64=4^x[/tex]

It can be rewritten as

[tex]4^3=4^x[/tex]

On comparing both sides by get

[tex]3=x[/tex]

The value of x is 3.

Since f(3)=64 it means the population of bacteria is 64 in 3rd hour.

Therefore the correct option is A.

A five carbon sugar is a monosaccharide that contains five carbon atoms and is found in nucleic acids. Examples include ribose and deoxyribose.

A five carbon sugar is a monosaccharide that contains five carbon atoms in its structure. Two examples of five carbon sugars found in nucleic acids are ribose and deoxyribose. Both have a cyclic form with a hydroxyl group at the anomeric position.  Five-carbon sugars, or pentoses, are crucial components of nucleic acids like DNA and RNA. Ribose and deoxyribose are common examples.

Their distinctive features include a five-carbon backbone, where each carbon is attached to a hydroxyl group. In RNA, the 2' carbon of ribose contains a hydroxyl group, distinguishing it from deoxyribose in DNA. The arrangement of these carbons and hydroxyl groups contributes to the unique structure and function of these essential building blocks in genetic materials.
