Answer: d. exoskeletons are external to the soft tissues, and endoskeletons are internal
Explanation:
The skeleton can be define as the body part of the living beings which act as a supporting structure which maintains the posture and provides the supporting framework to the body. The exoskeleton is the skeletal structure that protects the body from outside. It encloses within it the soft tissues and organs of the body. It is the characteristic feature of the invertebrates. It is the external feature of the body. It also provides protection against the predator. The endoskeleton is the skeletal structure which serves as a attachment point for the muscles. It is the internal feature of the body.
Answer:
The algae can release harmful chemicals known as "bio-toxins" that can contaminate the water and kill the organisms living in the ecosystem
Explanation:
Answer: number 1 is zygote
Answer:
Both perform photosynthesis.
Explanation:
Both perform photosynthesis led researchers to propose that Chloroplast evolved from Cyanobacteria.
Chloroplast is a organelle that contain the green pigment called chlorophyii which perform photosynthesis. This is found in both plant cell and algae cell. This trap light energy from sunlight and uses carbondioxide with water to produce sugar.
Cyanobacteria are known to be the ancestor of chloroplast and they are also refer to as blue green algae because they contain chlorophyii which is a photosynthetic pigment. The Cyanobacteria are able to perform photosynthesis because of chlorophyii which trap light energy from sunlight and uses carbondioxide and water to produce energy.
