Answer:
3-animals with simple body plans have a digestive compartment with one opening, whereas organisms with complex body plans have digestive tubes with two openings.
Explanation:
Here is the complete question
Q1:A main difference between organisms with simple body plans and those with complex body plans is that
1-animals with simple body plans can ingest food while earlier meals are still being digested, whereas animals with complex body plans cannot.
2-animals with simple body plans have digestive tubes with specialized compartments, whereas animals with complex body plans do not.
3-animals with simple body plans have a digestive compartment with one opening, whereas organisms with complex body plans have digestive tubes with two openings.
4-animals with simple body plans eliminate undigested food via an anus, whereas animals with complex body plans eliminate undigested food via a mouth.
5-animals with simple body plans have digestive tubes with two openings, whereas organisms with complex body plans have a digestive compartment with one opening.
Explanation
This because animals with simple body plans like amoeba have one opening for ingesting and egesting food and waste product. Their digestive compartments thus have only one opening. Whereas, animals with complex body plans like man, have a digestive system which has two openings. One at the anterior of the organism which is its mouth and the other at its posterior which is its anus. The mouth is used for ingesting food while, the anus is used for egesting waste food products.
Answer:
One chromatid compares to its sister chromatid because when a chromatid is replicated, a sister chromatid is formed. The sister chromatid will be a genetically identical copy to the chromatid because the cell being replicated will also be genetically identical.
Answer:
because they reduce interspecific competition
Explanation:
Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.
The cell theory includes that D) All living things are made up of cells.
The cell theory states that all living things are made up of cells, that all cells come from previously existing cells, and that the cell is the simplest unit of life and is the foundation on which more complicated levels are built upon.
All living things are made up of cells, and cells are often classified as the simplest unit of life (the least organized level which still constitutes life). All of the other levels are built upon the cell, including tissues, organs, organisms, and even ecosystems.

Correct answer is c - Blood cell are produced in the skeletal system.
Red blood cells are produced on a regular basis in the bone marrow. Bone marrow is a red spongy material found within the cavities of many of the large bones of the body.
Red blood cell start as immature cell in the bone marrow and after about seven days of maturation, they are released into the bloodstream, that is, the circulatory system where they circulate for about 120 days before being replaced with new ones.
