euglena

Answers

Answer 1

Answer:

Answer:

paramecium is the correct answer.

Explanation:

A common protozoan that moves by cilia is the paramecium.

paramecia are the single-celled organism, they live in the aquatic habitats.

The whole body of the protozoan is covered by cilia.

Cilia is hair-like organelles that help the paramecium to swim in the water as they have streamlined structure.

The function of cilia in the life cycle of a protozoan is it help in locomotion and in food ingestion.

What is the main function of the circulatory system in multicellular organisms?A.
to bring oxygen into the lung

B.
to put carbon dioxide into all blood vessels

C.
to expel waste products from the body

D.
to transport materials throughout the body

Answers

The answer here is D because it covers the other options namely A and C while B is not really true.
Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and metabolic waste taken away in a continuous, never ending process.
A mechanism is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this bill splendidly. It is a specialized organ system which allows blood and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs to be expelled from the body.

Choose all the answers that apply.Which of the following increases erosion?
clearing forests
leaving fields unplanted
careless farming
contour plowing
crop rotation
--

Contour plowing occurs when:
farmers plow fields in horizontal rows
farmers stop plowing fields
farmers plow fields around hills
farmers plow fields around brooks and steams

Answers

Answer:

clearing forests

careless farming

2:farmers plow fields around hills

Explanation:

Erosion is caused by the debilitation of the soil, and one of the most common reasons for erosion is clearing forests, also called deforestation, plants and their roots help keep the soil in their place and use the water that runs through the soil helping avoiding erosion, Plowing fields are fields that take advantage of the elevation in the soil and plant in different levels of elevation, helping with this to prevent erosion in the soil.

careless farming and the second one is farmers plow fields in horizontal rows^-^
