a circle fence sourrounding a small yard mesure 84 meters in length if you walk from one side from the other through the middle what is the distance across the small yard
Answer: 26.75 meters.
2πr = 84
2 * 3.14 * radius = 84
radius = 84/6.28
r= 13.375
So the diameter will be 13.375 + 13.375 which is 26.75 meters.

Individuals, as well as industry—and automobile manufacturers in particular have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere. Agree or disagree
It is right that individuals, as well as industry—and automobile manufacturers, in particular, have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere.
Carbon dioxide is a greenhouse gas, which means that it traps heat in the atmosphere. This can lead to climate change, which is already having a number of negative effects on the planet, such as rising sea levels, more extreme weather events, and changes in plant and animal life.
Individuals can reduce their carbon dioxide emissions by making changes to their lifestyle, such as driving less, using less energy at home, and eating less meat. Industry can reduce their carbon dioxide emissions by investing in new technologies, such as renewable energy and energy efficiency.
Automobile manufacturers have a special responsibility to reduce carbon dioxide emissions, as cars are a major source of greenhouse gases. They can do this by designing more fuel-efficient cars and by using alternative fuels, such as electric and hybrid cars.
It is important for everyone to do their part to reduce carbon dioxide emissions. By working together, we can help to protect the planet for future generations.

How are seeds produced
Answer:
From other seeds
Explanation:
They grow more seeds form the one seed
Answer:
From plant reproduction.
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.
Which letter on the diagram below shows where M phase would occur?
Answer: D
Explanation:
Which of the following happens during interphase?
Answer:
Interphase is the portion of the cell cycle that is not accompanied by gross changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). ... In interphase, the cell gets itself ready for mitosis or meiosis.

Students were given a list of seven elements and asked to identify the four elements that are most abundant in biomolecules. Which table correctly identifies the four most-abundant elements in biomolecules?.
Answer:
Carbon, hydrogen, nitrogen, oxygen
Explanation:
Not sure what the tables are?
Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.
The four most abundant biomolecules are:
Carbon, Oxygen, Nitrogen and Hydrogen
The biomolecules can be explained as:
The central biomolecules for life activities are these elements that contribute to major processes.The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.

Why a cell spends the majority of its time in interphase.
A cell spends the majority of its time in interphase because during this period the cell grows and synthesizes materials required during and after its division. During interphase, the cell duplicates its genetic material.
The cell cycle can be divided into a long interphase and a short mitotic (M) phase.
The interphase can in turn be divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material, which is sharply controlled by different cellular mechanisms (e.g., checkpoint mechanisms).
During G1 and G2 phases, the cell synthesizes all the proteins required during the M phase and after cell division.

A. gamma rays
B. infrared radiation
C. microwaves
D. x-rays
Given what we know, we can confirm that both gamma rays and x-rays can be used to slow the decay process in foods.
What are gamma rays and x-rays?Both of these are forms of ionizing radiation. Applying these to food is known as food irradiation. What this accomplishes, is that the food that is irradiated will have its chemical bonds altered, slowing the decay process.Therefore, since both gamma rays and x-rays offer ionizing radiation to the food, which affects the chemical bonds and allows the food to have a longer shelf life, we can confirm that they can be used to slow the decay process in foods.
