Every single one here looks correct except for the last one involving algae, frog, and rabbit considering they are organisms, therefore it should be organism.
Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.
Organisms are classified according to a system of seven ranks:
1. Kingdom
2. Phylum
3. Class
4. Order
5. Family
6. Genus
7. Species
For example, the honey bee (Apis mellifera) would be classified in the following way:
1. Kingdom = Animalia
2. Phylum = Arthropoda
3. Class = Insecta
4. Order = Hymenoptera
5. Family = Apidae
6. Genus = Apis
7. Species = Apis mellifera
Species names are always written including the Genus in either full or abbreviated, for example, Apis mellifera or A. mellifera respectively.
Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
- <em>Negative feedbacks</em>
- <em>Positive feedbacks</em>
Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
Answer:
Tissues in organs are precisely arranged so that they can work in harmony in performing organ functions. This is similar to an orchestra that contains various musical instruments, each of which is located in a precise place and contributes exactly at the right time to create harmony. Like musical instruments that are mixed and matched in various types of musical groups, tissues and cells also are present in several different organs and contribute their part to the function of the organ and the maintenance of homeostasis.
Answer:
Species C is the most common ancestor of species 1 and 4.
