What are the two phases in the m phase

Suppose that the plasma membrane around a eukaryotic flagellum is opened to reveal the axoneme inside. the radial spokes connect

mash [69]

The flagella of the eukaryotes is composed of the doublet microtubules. The central bundle of these microtubules is known as the anoxeme. In an axoneme, a single pair of the singlet micortubules is surrounded by the nine doublet microtubules. When the plasma membrane of the flagellum is opened to expose the axoneme, and the radial spokes are broken, it will lead to the elongation of the axoneme,

Question 3

Anthropogenic cause of pollution are human causes of pollution. Some of these are:

Combustion of fossil fuels in internal combustion engines release harmful and toxic gases into the atmosphere and causes hair pollution.
Improper disposal of waste can produce effluent that reaches the ground water system and other fresh water sources.
Noise pollution from airports is very harmful to ear.
Mining activities degrades soil and removes rich fertile soils that should be used for agriculture.
Mining wastes can lead to contamination of water bodies around.

Question 4

Fossil fuels are fuel types that forms from natural process in which organisms are decomposed anaerobically to preserve their energy components. Some of these fuels are:

Coal
Crude oil
Natural gas

Question 5

Heart diseases ; ischaemic heart diseases can lead to failure of the heart when it does not receive enough oxygen from the environment. Air pollution contaminates available oxygen in the atmosphere and this is very dangerous to life.
Lung cancer: poor air quality can lead to the development of cancerous tumor in the lungs.
Asthma: air pollution is one of the leading cause of asthma.

Other notable mentions are bronchitis, pulmonary diseases, stroke

Question 6

_7 million____ people die each year from air pollution according to the world health organization

Question 7

Air Quality Index(AQI) is an indicator used to express the quality of air in particular area. The AQI can tell the present air quality condition. It can also be used to forecast future air quality in years to come.

It shows how clean and polluted the air is.

Question 8

The air quality index uses different colors to alert people about the quality of air. Each color represents different health implication of air quality:

Attached image shows the different colors used to alert people of about the air quality.

Question 9

About 7 million people die annually as a result of air pollution
Beijing cough is new disease that emanates from the rising air pollution in Beijing
Asia has the fastest rising cases of air pollution problems.

Jose and Fran MUST follow specific safety procedures when heating water with a Bunsen burner. The safety procedures include

8_murik_8 [283]

The following are some common procedures that we should take action of when using a bunsen burner to ensure our safety:

1. Wear safety goggles. Tie up long hair and school ties if needed. This can lower the risk of catching on fire. Put a heatproof mat underneath the Bunsen burner, put a tripod and the beaker of water for heating on top of the burner.

2. Close the air hole. Before we start up the burner, the air hole must be closed or green flame (striking back) may occur

3. light up a match or a lighter. Put it over the chimney.

4. Turn on the gas tap, you should be able to see a yellow flame now. Remove the lighter or match and open the air hole. We should have a blue flame by now.

5. the water should start to heat up. Never touch the hot beaker with bare hands.

6. When the water is heated up to the temperature they wanted to, it's time to close the air hole and turn off the gas tap.

7. If they need to move the hot beaker, use heat protection gloves

These should be the correct procedures that they should follow in order to heat the water safely.

Hope it helps!

Rainforest deforestation is contributing to _______.

Nana76 [90]

The correct answer is letter A.

Rainforest deforestation is contributing to a decline in global biodiversity. Irresponsible logging causes the major destruction of many habitats. As a result, many living organisms that are thriving within these forests are displaced or are killed because they no longer have any place where they can thrive and live in peace with their respective species. Deforestation accounts for most of the major catastrophic natural events that we are experiencing at present.
