Human reproductive system

The human reproductive system is probably the most sensitive part of your body. this is bow you are bought in this world an the way the this happened is a vary big cycle with a lot to learn about this particular subject this is a new open world of pure science.well then lets start with the basic stuff the male cells.” sperm” cells are a genetic information carrier the carry all the info that is needed to make the baby. Did you know that a baby might contain genetic information from possibly your assessors! For example if you have blue eyes and your partner ha green Moby your baby will have black eyes! now we move on to the female cell the egg cell which the sperm has to penetrate it but before any of that happens there is a huge cycle. the female cell also contains genetic information.

Air

well Air is every where and not only that we don’t see it and feel it we just know of it.

Air is what keeps us alieve the be more specific it’s what’s inside it is what keeps us alieve. Air contains gasses like oxygen helium carbon dioxide and more. Let’s look at this…

 

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere

 

The rock cycle

The rock cycle involves changes to rocks both inside and outside the earth .

the rock sucked involves the three type of rocks(igneous,sedimentary and metamorphic).

the weather brakes down rocks into smaller bits there are few different ways this can happen like the the onion skin when day by day the rock will expand and contract then eventually it will turn into bits and peaces intel it will erode away

erosion is when the rock wears out by rain

transportation is when the the eroded rock travels around the world by a natural mode of transportation.

Photosynthesis

photosinthasis is how plants make their own food by sunlight. how photosinthasis works is simply using sunlight,co2,water and nutrition to make glucose for biomas(to grow).

well now we will talk about the leaf which has a lot of features like… the stomata is mostly at the bottom of the leaf to inhale and exhale.

 

Inhale      Exhale

Co2       Oxygen

so they breath what we exhale and we breath what they exhale.

Also in the leaf there is the xylem and Phloem which do the following…

xylem=to transfer food around the leaf

phloem=To transfer water around the body

Back to the plant it self the equation to photosinthasis is…

 

Co2+water>sunlight&oxygen gluecos+oxygen

Also at the very top of the plant there is the chloroplast and the chlorophyll to absorb all the sunlight it can get just like solar panels so they will go to no use if they were at the bottom.

heart

The human heart

an heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes

The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes.

Gas exchange system

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick)

Group One Metals

Group one metals are very reactive metals, they can react with the tiniest water molecules in air. That’s reason why they have to be stored under oil. Also they bare the vertical column on the left hand side of the periodic table. The following metals are in group one:

lithium=Li

sodium=Na

potassium=k

robidium=Rb

cisium=cs

francium=Fr

when lithium reacts with water it flows and fizzes until it becomes smaller and disapers.

lithium +water=lithium hydroxide+hydrogen

Atoms and Elements

An atom is the smallest thing discovered it contains electrons (which has a negative charge) neutrons (which has no charge) and protons (which has a positive charge).

An element is a substance which only contains one atom e.g gold only contains one atom which is gold atom. But all elements have different properties like copper is a soft beady metal and oxygen is a colour-less gas. All the elements on the left hand side of the periodic table are metals while elements on the right side of the  periodic table are none metals.

Mendeleev created the periodic table. The vertical columns are are called groups and the horizontal rows are called periods, all groups have different proprieties like group 1. has all shiny metals that react with water.

Drugs

A drug is a substance that changes the way that your body works. there  are two types of drugs legal and illegal drugs

legal                                           illegal

calpol                                          weed

Aspirin                                       cocaine

Alcohol is a type of drug that is found in beers, wines and spirits some can be legal and some can be illegal in some countries. alcohol decreases the activity of the brain, that is  why you can not be drunk driving because it slows down your reaction time and affect your judgement. Also it is a recreational drug.

Illegal drugs are addictive,  dangerous and life wrecking.

LSD and Ecstasy are hallucinogens that make you hyper/high and gives you lots of energy

space

 

space is surrounding the earth. High above the atmosphere of the earth, there is an entire new world to explore such as planets,stars,solar systems and even galaxies. They all make up what we call the universe  which remains unexplored until this second. All of this started with a theory called the big bang. Although space is largely empty even though it contains planets, stars and galaxies.

A planet is an object that orbits

#around a star.Among our solar system there is a planet called  earth, it has a inner core, outer core, mantle and the crust. The Earth came from a cloud in space which was made from a large amount of dust and gas. Earth was formed over billions of years ago, this dust whizzed around the sun and joined together to form lumps of rocks which then crashed into each other to form planets of like planet earth.                                               Image result for big bang explosion

The sun is part of a huge family of stars called the milky way which is our galaxy. Billions of stars combine together to make a galaxy. there are different forms of galaxies eliptical,spiral with a bar across the middle, spiral and irregular.
