Monera
Explanation:
Modern taxonomy classified living things into five different categories:
- Plants
- Animals
- Fungi
- Protists
- Monera
- Monera is a kingdom of life that is made up of unicellular prokaryotic organisms.
- They are made up of organisms with no true nuclear membrane.
- They are made up of bacteria and Archea
- Organisms of the Monera kingdom are beneficial to man and also causes diseases.
- They are ubiquitous and nearly found every where.

If a p53 gene is defective it may cause cell cycle to stop functioning normally. Without this cell cycle check, cells will divide continuosly creating many chromosomal damage.
Answer:
Watching a baby hummingbird grow up can be a very rewarding experience. Knowing what to look for will help you understand what the hummingbirds are doing and why they are doing it.
Costa's Hummingbird, Calypte Costae, Nest with Eggs, California, USA
Baby hummingbirds are hatched out of hummingbird eggs. When a mother hummingbird is laying an egg, she can be seen sitting on her nest and shaking alternated by wiggling every few seconds. Mother hummingbirds will usually have two eggs laid on different days. The little eggs will be about the size of a pea or small jellybean. Even though the eggs will be laid on different days, both the eggs will usually hatch on the same day. The mother hummingbird can do this by not completely starting the incubation process until the second egg is laid.
The female hummingbird is the only one who will care for these little eggs. A male hummingbird does not assist with any of the childcare. In fact, if a male hummingbird comes around, the female hummingbird will consider his brightly colored feathers a threat that will attract predators and will chase him away.
The hummingbird eggs will remain in the nest incubating for approximately 16-18 days before they hatch. If the weather is cooler it may cause them to hatch a few days later. While the eggs are incubating in the nest, the mother hummingbird will sit on eggs to keep them at a constant temperature of 96 degrees.
Explanation:
Gamma rays
Explanation:
In a nuclear reaction product that has the least mass is gamma rays.
There are three types of ionizing radiation produced in nuclear reactions. They are:
- Alpha particles
- Beta particles
- Gamma rays
Alpha particles are heaviest followed by beta particles. Gamma rays have no mass.
- A gamma ray is a form of electromagnetic radiation
- It has no charge and mass

Answer:
The correct answer is D. The cytochromes
Explanation:
Cytochromes are proteins which contain tightly bound heme metal which easily undergoes oxidation and reduction and are responsible for accepting and donating the electron. They play an important role in the electron transport chain and helps in formation of ATP during oxidative phosphorylation.
The metal ion provides the capability to the cytochrome to gain and loss the electron. a, b, and c are the three classes of cytochrome out of which cytochrome c is the most abundant and stable.
Therefore the redox carrier of ETC that have bounded metal atom are cytochromes.
