LAMARCK's THEORY
Jean Baptiste Lamarck (1744-1829) proposed a theory which was published in "<em>Philosophie Zoologique"</em> (1809). This theory is simply known as Lamarckism. It has two main postulates:
1. Use and disuse of organs
2. Inheritance of acquired characters.
Example
He explained his theory by giving the examples:
1. Neck length of Girrafes
2. Webbed toes of water birds, and
3. Wings of penguins
Explanation
Lamarck explained that water birds use toe for swimming, with the passage of time webbed were developed in their toes. these features were then transferred to their offspring.
Drawback
Lamarck theory was based on natural observation. It did not explain the genetic basis of such characteristics.
Answer:
producers that make their own organic matter from inorganic molecules
Explanation:
Phosynthetic organisms are those that capture solar energy and can be used in the production of organic compounds. Through this process they are able to make their own food based on something as simple as sunlight, the organisms that are in this group are: higher plants, algae, some bacteria, which can convert carbon dioxide into organic compounds and of these compounds reduce them into carbohydrates.
The energy necessary for this process to occur, is generated through the light of the same sun, which promotes the activity of these organisms for the preparation of organic compounds and their carbohydrates, which are used by cells as a source of Energy.
It is important to note that most of the foods that are consumed throughout the day and the fossil fuel that is found in nature, are a product of this process called photosynthesis. Photosynthetic organisms are considered to be the largest primary producers within the same trophic chain itself, since among them are those that produce oxygen, which are green plants, algae and some bacteria. But there are also organisms that produce photosynthesis and do not produce oxygen, among these are purple sulfur bacteria and green sulfur bacteria.
Answer:
The Answer is
D. Fewer Hydrogen ions will be pumped into the thylakoid
Answer: The mass number is 13
Explanation:
Mass number = Protrons + neutrons;
While Atomic number = Number of neutrons
Therefore, if the atomic number of nitrogen is given as 7, then its Protrons = 7
So, mass number = 7 + 6 = 13
