I would say the last one. Yes, the coral reef in the south is being threaten but, it’s not the only one. Many other reefs are being threatened. Why? To find the problem to this reef you need to find the problems of other reefs and compare the data. Which ever the most problem cause you get rid of that first.
Answer:Proteins have many different functions, while DNA has limited functions.
Explanation:
Chemicals that make up the living organisms consists of more protein than DNA. This is because proteins have different functions while the function of DNA are limited. Excluding water and fat, the human body is made up almost entirely of protein. Most of the structural framework of the body such as bones, muscle, organs, skin and nails are made up of protein.
Protein are responsible to do most of the work in cells by acting as enzymes, hormones and carriers. Proteins are largely required for the structure, function, and regulation of the body's tissues and organs.
The producers at the beginning of the Earth's food chain are plants.
Answer/Explanation:
In humans, we breathe in oxygen via the respiratory system. The oxygen enters the lungs. The air sacs in the lungs - the alveoli - are the site of gas exchange in the lungs and are where the circulatory and respiratory systems interact.
The alveoli take in the oxygen, where it diffuses into the capillaries (circulatory system). Blood, which passes through the capillaries takes this oxygen to all the cells in the body. Oxygen binds to haemoglobin in red blood cells, which transport it around the body.
Additionally, blood also transports carbon dioxide back to the alveoli of the lungs, where it diffuses into the lungs and is expelled when we breathe out
- The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
- Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
- A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
- Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
- Active transportation comes in two flavors:
- Primary active transport
- Secondary active transport.
