Explanation:
carbon dioxide is emitted during cement production by fossil fuel combustion .
Answer:
The correct answer is option c. "old layers of xylem and phloem".
Explanation:
Wood is one important good used for construction obtained from the main substance of the outer layer of the trunk or branches of a tree. Biologically, the outer layer of the trunk of a tree is comprised of the old layers of xylem and phloem, which are dead cells that were part of the heartwood or the centre of the tree. These old layers of xylem and phloem form the outer bark structure of the tree.
Answer:
What is the difference between the terms Matter and Element?
- Anything that occupies space and has mass is called matter. It can be solid, liquid or gas.
- Element is smallest classification of matter, which cannot be sub-divided into simpler components by chemical means.
What is an atom?
- An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
What are the 4 most common atoms to the human body?
- The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
What are molecules?
- A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.
What is a chemical reaction?
- A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.
According to the Rules of Atoms, will the carbon in carbon dioxide be around in a million years? How likely is it the carbon dioxide molecule will be around? What is your reasoning?
I don't know, this one you can answer yourself
Explanation:
Answer:
Position 2
Explanation:
Since it is on the Tropic of Capricorn, for it to be exactly on top of Africa, it must be in position 2. The Tropic of Capricorn is special because the sun is directly on top of it when the south part of the Earth is facing the sun, like position 2. Position 1 and 3 are directly at the Equator because neither part is tilted towards or away from the sun. Position 4 is directly above Tropic of Cancer. The Tropic of Cancer, like the Tropic of Capricorn, has the sun directly on top of it when the north part of the Earth is tilted towards the Sun.
I hope this helps!!! :)
Answer:
Arp2/3 and formins differ in their mechanisms of actin polymerization
Explanation:
The actin cytoskeleton plays key roles in diverse cellular processes including, among others, morphogenesis and endocytosis. The Arp2/3 complex and formin family proteins are two different types of actin-binding proteins capable of modulating the dynamics of actin filaments. The Arp2/3 complex is well known to have a key role in spine morphogenesis by promoting the branching of existing actin filaments. On the other hand, formin proteins induce the formation of plasma membrane protrusions by promoting the formation of unbranched filaments.
