The ability to do a task with little to no waste, effort, or energy is referred to as efficiency. Being effective is using the resources you have as effectively as possible to attain your goals. Simply put, if there is no wastage and all procedures are optimizer, something is efficient.

When employees complete the proper jobs in the proper manner with the least amount of time and effort wasted, they are being efficient. Ultimately, increasing workplace productivity involves assisting workers in doing more with less.

Solution:-

Ronald applied 640 joules of energy to the inclined plane.

How to calculate the energy input

Efficiency, as we all know, is the ability to complete a task with little to no waste. In mathematics, it can be written as

Efficiency is defined as (output / input) 100.

The input energy can be found using the formula above as follows:

224 joules equal output work

35% efficiency

Work entered =?

Efficiency is defined as (output / input) 100.

35% = 224 / input

0.35 = 224 / input

multiply by cross

0.35 × input = 224

Add 0.35 to both sides.

Work input = 224 / 0.35

Work input = 640 joules

The energy input is 640 joules as a result.

False. Cytoplasm is not randomly distributed to haploid cells.

Haploid cells refer to cells that have a single set of chromosomes, as opposed to diploid cells that have two sets. The process of cell division, called mitosis, is responsible for the distribution of cytoplasm and chromosomes to the new cells. The cytoplasm and chromosomes are divided equally between the two daughter cells. The process is highly regulated and orchestrated to ensure that the cells have the correct amount of cytoplasm and chromosomes to function properly. It's important to note that, in some cases, in some organisms, such as fungi, there is a process called plasmogamy, where cells fuse, but their nuclei do not, resulting in a cell with multiple nuclei but a single cytoplasm.

The purpose of estuaries are being used for agriculture.

In order to provide cleaner waters for people and marine life, estuaries filter out silt and impurities from streams and lakes before they run into the ocean.

Estuaries serve as free-standing filters. Runoff from the land can carry sediments, fertilisers, and pollutants into estuaries, where a natural filtration mechanism can help keep some of them from entering the water supply.

Estuaries are valuable from a business standpoint, and the resources they provide are profitable for the tourist, catching fish, and recreational industries.

The number of protons in an atom is also referred to as the atomic number, so an atom of iron has 26 protons in its nucleus. The mass number of an atom is the sum of the number of protons and neutrons in the nucleus. So, to find the number of neutrons in the atom, we can subtract the number of protons (26) from the mass number (56):

56 - 26 = 30 neutrons.

So, the number of protons plus neutrons in the nucleus is:

26 protons + 30 neutrons = 56.

Tropism can be defined as the movement of plants in response to an external stimuli.

Tropism is a term which is used to describe how a particular plant responds to an external stimuli by growing, turning or moving towards or away from it. When the movement of plant is towards the stimulus, it is known as positive tropism and when the movement is away from the stimulus it is known as negative tropism.

For example, phototropism is the movement of a part of the plant in response to light. When the movement of plant occurs towards the light, it is known as positive phototropism and when it occurs away from it, it is known as negative phototropism.

what is photosynthesis ?

Photosynthesis is a process that plants and other organisms utilise to transform light energy into chemical energy that may then be released to power the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are created from carbon dioxide and water - thus the name photosynthesis, from the Greek "putting together". Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for creating and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

Explanation:

Option d is Correct. Darwin introduced the concept of natural selection (survival of the fittest). This hypothesis contends that more people are created with each passing generation, and they fight for survival.

Phenotypic variation exists among individuals and the variation is heritable; those individuals with heritable traits that are better suited to the environment will survive and reproduce. Those individuals that can inherit the adaptations according to the change in the environment will survive, and the rest will die.

Differential reproduction is what is done in this situation. At the time of reproductive isolation, new species (evolution) will develop. Natural selection is demonstrated by the industrial revolution in the black peppered moth.

These characteristics of R-selected species perfectly:

r-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O. Wilson; K-selected species—that is, species whose population sizes fluctuate at or near their carrying capacity (K)—make up the second strategy.

The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans. Unlike K-selected species, members of this group are capable of reproduction at a relatively young age; however, many offspring die before they reach reproductive age.
