Francesco Redi was a scientist that performed an experiment to determine whether maggots formed from rotting meat. Versions of his experiments are described below.
Meat was placed in two beakers. One of the beakers was left open to the air. The other beaker was covered with a fabric that only allowed air to get in. As the meat rotted, flies landed on the meat in the open beaker but were unable to get to the meat with the fabric over it. After a few days, maggots appeared on the meat in the open beaker, but not in the closed beaker.
In the next experiment, rotting meat was placed in two beakers. Dead flies were placed in one beaker, and live flies were placed in the other beaker. Both beakers were sealed, allowing no air in. Maggots appeared in the beaker with live flies, but not in the beaker with dead flies.
Explain how the surface area and volume of cells affect the rate of exchange of materials in and out of cells in multicellular organisms.
In order to test the spontaneous generation of maggots, an Italian scientist named Francesco Redi created an experiment in 1668 that involved putting fresh meat in two distinct jars. One jar was left open, while the other had a cloth covering it.
Redi came to the conclusion that the meat in the open jar had maggots because the flies had deposited eggs on it. No maggots were created because the flies were unable to lay their eggs on the meat in the covered container. Redi therefore shown that meat in decay does not breed maggots.
However, one of van Helmont's contemporaries, Italian physician Francesco Redi (1626-1697), conducted an experiment in 1668 that was among the first to disprove the notion that maggots (fly larvae) spontaneously develop on meat left out in the open.

How does canada benefit from taking part in the global community?
Answer:
Canada believes that inclusive growth requires the full and equal participation of women in the economy. In most countries, gender inequalities are greater among the poor. Canada has identified inclusive growth as an area for action because it is central to poverty reduction. Inclusive growth, development and sustainable peace are not possible unless women and girls are valued and empowered.
Canada’s international assistance will help build a more inclusive and prosperous world. Such a world will achieve gender equality, with women and girls equally contributing to and benefiting from economic opportunities.
Canada will support inclusive economic growth that helps the poorest, most vulnerable and marginalized generate, participate and benefit from economic activity. This includes support for sustainable agriculture, entrepreneurship, producer associations and cooperatives. It also means support to develop micro-, small and medium-sized enterprises and to provide access to decent work, particularly for women.
Inclusive growth: expanding the benefits
Over the past three decades, the world has made impressive gains in reducing poverty. Economic growth has helped lift more than one billion people out of extreme poverty in the developing world. In many countries, economic growth has resulted in increased incomes, better access to goods and services, and improved living standards. The private sector, which creates nine out of 10 jobs in developing and emerging countries, is essential to this growth.
At the same time, millions of people around the world continue to face poverty and inequality. An estimated 10.7% of the world’s population (766 million people) still lives in extreme poverty, on less than US$1.90 a day on average. The benefits of economic growth have not reached everyone equally, especially women.
Many countries now agree that a new approach to economic growth and development is required for poverty reduction. This would help achieve Goal 8 of the United Nations’ 2030 Agenda for Sustainable Development regarding decent work and economic growth. There should be better income distribution and improved access to, and management of, human, financial and natural resources.
Empowering women and youth economically offers a real way of making sure growth reaches the poorest and most vulnerable. It will also address the gender gaps that hold back growth and perpetuate poverty.
Promoting women’s economic empowerment and rights
Gender inequalities are usually greater among the poor, particularly in the areas of education, health and economic opportunities. Women shoulder more unpaid work and have less access to resources and financial services than men. This undermines the ability of women to undertake paid economic activities. In developing countries, women’s work is concentrated in the agricultural sector, and in low-paying and gender-segregated jobs with few social protections.
Yet women have the ability to transform their countries' economies and societies, as well as their own households. Women can do this if provided with equal access to resources and education, and if men do unpaid care work equally. Investing in women and girls is the right thing to do to fully realize gender equality. It is also the smart way to reduce poverty and inequality. Gender equality ensures that women and girls have opportunities to contribute to, and benefit equally from, economic growth.
To advance women’s economic empowerment and rights, Canada will:
support the full participation of women in economic decision-making and leadership;
help improve economic opportunities for rural women, focusing on improved incomes and productivity through sustainable agriculture
support technical and vocational training and entrepreneurship for women, including access to value chains
promote financial inclusion for women and equal access to capital, markets, digital technology and business development services
help increase access to decent and higher-value work for women, in line with international standards
promote labour, land, inheritance and property rights for women
help address unpaid work and care by supporting policy reforms and improved social protection
Improving our effectiveness: leveraging investment
Developing countries can become Canada’s future trading partners, creating opportunities for our own economy and middle class. The Government of Canada is developing a progressive trade agenda that will help ensure gender equality is fully considered in trade negotiations.

Systolic pressure is the pressure in the arteries at the peak of ventricular contraction, while diastolic pressure is the pressure in the arteries during ventricular relaxation.
Systolic pressure is the measure of the highest pressure in the arteries during a heartbeat. It represents the force exerted by the blood against the walls of the arteries as the heart pumps it out. The measurement is taken when the ventricles of the heart contract, pushing blood through the arteries. A high systolic pressure, also known as hypertension, increases the risk of heart disease, stroke, and kidney damage. A normal systolic pressure is considered to be between 90-120 mmHg. However, optimal systolic pressure is considered to be around 115mmHg. A systolic pressure that is consistently above 130 mmHg is considered high and may require treatment.
