Answer:

The cholodny-went model was proposed in 1927. This model explains the capability of the shoots to grow in the direction of the sunlight whereas the capability of the roots to grow downwards. The hypothesis suggested that both these directional growth occurred due to the asymmetrical distribution of the plant hormone, auxin. This model has been modified a number of times by other scientists but its general concept is accepted by most of the researchers.

alexira [117]

Answer:

gross anatomy, an anatomical region

Explanation:

Anatomy can be grouped into gross anatomy and superficial anatomy. Gross anatomy is the study of structures that are visible to the human eye i.e. without the aid of a microscope. The anatomical regions are those regions in the body that are easily seen by the unaided eye.

In this case, Luna is trying to study the name and locations of the lumbar, or lower back, area of the body. The lumbar is the vertebrae found at the lower back of the body. Hence, it is an easily visible internal structure when dissected, making it's study a form of GROSS ANATOMY.

Answer:

Plant-like:

presence of flagella

shows the absence of cell wall, though chloroplast may be present

Animal-like:

absence of cell wall, as well as chloroplast

Fungus-like:

feeds on decaying matter

enclosed by a membrane called a pellicle

slime mold belongs in this category

Explanation:

The protists can be classified into three groups (plant-like, animal-like, fungus-like) based on the method of nutrition, movement, and mode of reproduction.

Plant-like protists have chloroplasts and trapped sunlight to form food ad energy (photosynthesis). They also have flagella used for the movement.

Example: Algae

Animal-like protists are heterotrophs that cannot make their food. They do not have chloroplast and cell wall outside the cell membrane.

Example: Protozoa

Fungus-like protists are single-cell eukaryotes that have a protective layer outside the cell membrane called pellicle. They feed on decaying organic matter.

Example: Slime mold and water mold
