Chicken bones that are dissolved in vinegar for a week become flexible. This is due to elimination of <u>Ground substance</u> from the bone.

Since bones are living tissues, much like the meat we consume, they are abundant in essential micronutrients for our bodies. Elements, particularly calcium and phosphorus, as well as sodium, magnesium, and other trace minerals, are abundant in bone.

The bright pink candy known as "Chicken Bones," which is made of pulled sugar and has a bittersweet chocolate centre and a cinnamon-flavored coating, is highly regarded in Canadian Christmas customs. It is frequently used as a stocking stuffer and is a mainstay in grandma's candy bowl.

Collagen, a soft substance, and calcium carbonate make up bones. The acid in the vinegar, when the chicken bone was placed in the glass, dissolved the calcium carbonate, leaving only collagen. Our bones need calcium (the mineral in calcium carbonate) to be strong.

ANTONII [103]

Answer:

Amphibians begin their lives as eggs, The few eggs that get fertilized, and survive will hatch in 7-9 days. After the eggs of an Amphibian hatch they are called Tadpoles. Tadpoles breathe through gills like fish. ... Metamorphosis is the final process that changes the amphibian from tadpole to adult.

1)In your own words explain what air pollution is

Anna11 [10]

Explanation:

Question 1

Air pollution is the introduction of harmful gases and substances into the atmosphere that renders it unfit for use for life. Some of these toxic gases and particulates are:

Carbon monoxide
Carbon dioxide
Nitrogen oxides
Smoke
Dust particles
Soot

Question 2

Natural forms are the original nature or outlook of a substance. Examples of natural forms are:

Flowers
Leaves
Animals
Rocks
Shells
Corals

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.
The best way to reduce air pollution is by riding bicycles and walking more.

Some inbred strains of the weedy plant Arabidopsis thaliana flower early in the growing season, but other strains flower at late

RoseWind [281]

Answer:

a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.

b. The genotype of all the four plants are:

1st plant = Ll

2nd plant = ll

3rd plant = LL

4th plant = Ll

c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).

In case if the 2nd plant is self-fertilized, the expected progeny will be only early.

In case if the 3rd plant is self-fertilized, the expected progeny will be only late.

In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).
