Imagine walking through a tropical rainforest. You notice that there are different types of trees, birds, insects, and other org

anisms. A few weeks later you are taking a walk through the desert and notice that the trees, birds, insects, and other organisms are different than those you saw in the rainforest. Which of the following statements best explains the differences between each of these ecological systems?
A. Organisms in each ecological system have short dispersal distances and are confined to the area where they mate.
B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.
C. Organisms in each ecological system haven't had enough time to evolve the adaptations for the other ecosystem; with enough time they will evolve into the other ecological system.
D. Organisms in each ecological system are there by chance and their presence in different ecological systems does not have a biological explanation.

Answer:

B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

Explanation:

According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.

Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.

Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.

The correct option is B.

Answer:

B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

Explanation:

Every organism lives in a habitat, within which it lives in an ecosystem best suited for its need. An organism needs food, water and a favorable weather to live. For an organism to survive in an ecosystem, it needs to adapt to the conditions in that ecosystem, else it dies. Therefore, different types of organisms in different systems will have varying characteristics.

This is linked to Charles Darwin’s theory of evolution which implies that all organism in an ecological system evolve heritable traits suited for their environment.

Desmosomes form channels that allow each cardiocyte to electrically stimulate its neighbors. True False
dimulka [17.4K]

Answer:

False

Explanation:

The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.

The correct answer is: 2.metaphase.

Mitosis is a process of cell division and it is separatd into phases.

• Interphase-DNA replication (two identical full sets of chromosomes),

• Prophase-chromosomes composed of two sister chromatids with identical genetic information,

• Metaphase- chromosomes line up along the centre of the cell,

• Anaphase- chromatids are pulled apart by the mitotic spindle (one chromatid to one pole and the other chromatid to the opposite pole),

• Telophase- a full set of chromosomes at each pole of the cell.
