Endoskeleton is an internalised skeleton which is found inside the body of the animals which possess it while exoskeleton is a type of skeleton that is found outside the body.

Monkeys, fish, and gecko are the answers.

What happens before mitosis occurs? A. The cell takes a rest./ B. Cytoplasm from the parent cell becomes two daughter cells./ C. The cell grows and makes a copy of its genetic material./ D. The genetic material of the parent cell multiplies into two sets.

Answers

Just before mitosis occur in a stage known as Interphase the cell grows and makes copies of its genetic material in preparation for the cell's division into two identical cells. Therefore, option (C) is correct.

What is mitosis?

In the study of cell biology, the phase of the cell cycle known as mitosis is the stage at which replicated chromosomes are partitioned into two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.

Conventionally, the process of mitosis is broken down into five stages that are referred to as prophase, prometaphase, metaphase, anaphase, and telophase.

Why do you think that parasitism exists, when one of the organisms is harmed by the relationship?

Answers

Because although one organism is harmed, the other benefits. So the organism that benefits won't stop the action that is harming the other. Hope that makes sense!

How do organisms store and use energy?

Answers


Plants store energy in form of starch usually in the roots and/or stem. When there is need for energy such in respiration, starch is converted to glucose which is then used to fuel the process of cellular respiration.

In animals, energy is stored in form of glycogen in the liver and muscle tissues. When there is demand for energy, glycogen is converted back to glucose, which is taken in by the cells and used to fuel cellular respiration

In both plant and animal cells, the purpose of respiration is production of ATP (or adenosine triphosphate), which is the form of energy that cells use.

 

How you do this and I need help

Answers

Consumers make up the
next trophic level; and must
eat other organisms to obtain
their energy. Consumers, in
turn, occupy different trophic
levels. Trophic levels of
common aquatic organisms
are shown in table 1.
Primary consumers are
herbivores, they eat plants.
In our aquatic ecosystem
example, zooplankton feeding
on phytoplankton occupy the
primary consumer trophic
level. Cattle are primary
consumers in terrestrial
ecosystems.
Secondary consumers,
represented by certain aquatic
insects are carnivores and
feed upon primary consumers,
the zooplankton.
Our example also includes
a tertiary consumer, the
largemouth bass that feeds
upon other carnivores.
