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.

Answer 1
Answer:

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.
Answer 2
Answer: i believe the answer is c because there are 3 domains: Archaea, Bacteria, and eukraya.

Plants get their food by _____. absorbing it through their roots conducting photosynthesis absorbing it through their leaves none of the above

Answers

Answer: The correct answer for the blank is -

Photosynthesis.

Photosynthesis is a process of formation of food (glucose) by utilizing carbon dioxide and water (as reactants) in the presence of sunlight in green plants and algae.

During this process, a green colored pigment called chlorophyll, first absorbs energy from sunlight (light dependent phase) and converts it into chemical energy in the form ATP and NADPH.

This energy is then utilised in the next phase (light independent phase) for the formation of carbohydrate.

Final answer:

Plants get their food by conductingphotosynthesis.

Explanation:

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose (a form of sugar) and oxygen. This process takes place in the chloroplasts, which are specialized organelles found in plant cells. Through photosynthesis, plants are able to convert sunlight energy into chemical energy, which they use as their source of food.

Thus, is a vital biological process in which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. This energy-capturing mechanism occurs in chloroplasts and sustains life on Earth by producing oxygen and providing a source of organic compounds for organisms in the food chain.

a population ecologist determines the number of a oak trees per square unit in a forest. what is he trying to infer by doing so?

Answers

The population ecologist is trying to determine the density of the oak trees in a forest. It is a part of the job of a ecologist. By detecting the density of the oak trees, an ecologist can easily determine whether the density of the oak trees are decreasing or increasing with time and what are the steps that need to be taken to keep the balance.

Two advantages for plants to grow on the branches of trees

Answers

The two main advantages for plants to grow on the branches of trees are better access to sunlight and protection from predators.

Better access to sunlight: Trees grow tall, so the plants that grow on their branches have better access to sunlight. This is especially important for plants that need a lot of sunlight, such as epiphytes.

Protection from predators: The branches of trees provide a safe haven for plants from predators. This is especially important for small plants that are easily eaten by insects or animals.

a cat paw and a bat wing are examples of choose one: a. artificially selected structures. b. embryonic structures. c. homologous structures. d. vestigial structures.

Answers

Answer:

Homologous structures

Explanation:

Homologous structures are anatomical features that are similar in structure and origin but may have different functions.

In the case of a cat's paw and a bat's wing, they both have a common underlying structure (similar bone arrangement), but they serve different purposes.

This similarity suggests a shared evolutionary ancestry, as these structures have been modified over time to suit the needs of different species (cats and bats).
