Answer:
Operons can be used to coordinate the expression of multiple proteins in combination in the prokaryotes. An operon is a fundamental unit of DNA that transcribes, translates, or splices an array of genes under the guidance of a single operator and promoter.
The expression of genes can take place in combination or not at all. The regulation of operon can either be positive or negative due to repression or induction.
Answer:
The correct terms or tissues are :
mesenchyme
chondrocytes
fibrocartilage
stratified epithelia
reticular connective tissue
Explanation:
1. Mesenchyme is comprised of loose cells embedded in a mesh of proteins and fluid that makes the middle portion of the unspecialized mesoderm from which cartilage, bone, and blood develop.
2. The mature cells that live in cartilage and maintain the matrix around them are chondrocytes.
3. Fibrocartilage is a type of cartilage with a net of collagen fibers to help resist compression and tension.
4. Any tissues that exist in layers and form linings or coverings fall into the category of stratified epithelia.
5.. Reticular connective tissue is the type of connective tissue that is a supportive structural network fibre to support other cells.
Answer: B) The experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Explanation:
The most logical third step in Connell's experimental procedure, permitting him to either accept or reject his hypothesis of competitive exclusion is the experimental group tests to see if the presence of Balanus in some manner prevents Chthamalus from growing.
Balanus is a species of crustacean, as know as sea acorns, whereas Chthamalus is a species of barnacles that can easily be found in the northern hemisphere's coasts.
The dog gets warm from the fire when heat energy is transferred by radiation.
Light waves are the energy that is created when burning wood. Different light waves of various energies combine to form flames. The energy of light is converted into heat when these light waves are absorbed by the dog's body, warming it.
Hence, radiation waves are the result of moving energy.
Therefore, radiation is the right response.
