The correct answers are:
Trematodes are acoelomates that have effective defenses against attack by their hosts' immune system.
Trematodes are flatworms, internal parasites known as flukes. Their life cycle is complex: they sexually reproduce in vertebrates and asexual reproduce in mollusks (mostly snail). The body of flukes is covered with tough tegument that defends them form digestive enzymes of host’s intestine.
Cnidarians are diploblasts that produce complex, capsule-like organelles.
Cnidaria are water organisms with simple structure: two layers of epithelium and a jelly substance between them. The cells of Cnidaria-cnidocytes contain capsule with venom substance in it with protective role.
Answer:
light energy, water, carbon dioxide and chlorophyll
Two questions have been asked, and responded to
Answer:
For question 1: The statement is true
For question 2: Yes, the two wild roses are of the same population
Explanation:
Population is simply the total number of organisms of the same species LIVING and BREEDING together in a given area.
I) To be considered part of the same population, two of more organisms MUST BE able to mate i.e produce gametes that are viable enough to fuse together and create new offsprings.
2) Yes! Two wild roses separated by a wide road belong to the SAME POPULATION because
- it is still a given area or habitat
- transfer of pollen grains by agents such as wind or insects is possible, thus breeding still occurs.
Answer: Animals undergoing examination should be restrained with just enough force to calm them and keep them still so that the veterinarian can provide proper veterinary care. Each animal's restraint needs will be different and dependent on their behaviors and anatomies.
Answer:
Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
