Antibiotic used to cure bacterial infections that is obtained from fungi of the Penicillium genus .

Scientist Fleming discovered by accident that there was a fungus capable of killing some bacteria. In this way, he had some culture plates (small plates of glass or plastic in which the microorganisms can grow) that remainded forgotten and contaminated with mold, and around the growth zones of the fungus, he could see that there were no bacteria. Intrigued, he began to study that phenomenon.

The five-kingdom system of classification reflects the idea that all organisms can be separated into two main groups: prokaryotes and eukaryotes. The new six-kingdom system recognizes three broader groups that include six kingdoms. How do the three basic groups of the six-kingdom system differ from those of the 5-kingdom system? A) The six-kingdom system has three domains in order to includes a new kingdom for viruses. B) The six-kingdom recognizes the vast differences in protists and divides them into two kingdoms. C) The six-kingdom system has three domains: two domains separate all prokaryotic organisms into two new groups. D) The six-kingdom system adds a broader classification of domain to divide all living things into three groups: microorganisms, plants, and animals.

Answers

Answer;

C. The six-kingdom system has three domains: two domains separate all prokaryotic organisms into two new groups.

Explanation;

The six-kingdom system has three domains: two domains separate all prokaryotic organisms into two new groups.
Organisms are classified into three Domains and into one of six Kingdoms of life. The three-domain system has Archaea, Bacteria, and Eukarya, while the Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.
All eukaryotic organisms are in the domain Eukarya. Prokaryotes are divided into two kingdoms and two domains, Archaea and Bacteria.

i believe the answer is c because there are 3 domains: Archaea, Bacteria, and eukraya.

Which discovery could provide evidence against the theory of evolution? A. primate and trilobite fossil in the same rock layer
B. human gene in birds, fish, insects and plants
C. a living whale with a basic hip bone structure
D. bat fossil with a different limb structure than modern bats

Answers

Answer:

The correct answer is A. primate and trilobite fossil in the same rock layer

Explanation:

Trilobita is a class of marine arachnomorph arthropods that become extinct at the end of the Permian mass extinction about 250 million years ago. They were one of the most successful animals on earth and lived around 300 million years even more that dinosaur.

The fossil of early primates are nearly 55 million years old and the trilobite become extinct at least 250 year ago, therefore, this discovery provides evidence against the theory of evolution because the fossil of animals who extinct earlier should be found in lower region of soil than the fossil of animals who extinct later. Therefore the correct answer is A.

B. because first of all those animals evolved before humans, and also from very different species than did humans. If humans have plants as their descendants/ ancestors that would make us question everything we know about our existence.

What role does cellular respiration play in the carbon cycle

Answers

Answer:

Cellular respiration is a cellular process by which the organism in the presence of oxygen breakdown glucose and release energy that is stored in the form of ATP.

The by product of this process is carbon dioxide and water. This carbon dioxide is used by plants for the process of photosynthesis.

This is one of way by which carbon dioxide is provided to relay the carbon cycle.

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
