DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
Answer:
The five categories of vertebral column are:
- Cervical
- Thoracic
- Lumbar
- sacrum
- coccyx.
Explanation:
The 26 vertebrae of the spine or vertebral column are classified into five categories based on the structural differences between them. The first category is cervical and is made of seven cervical vertebrae. The spines of cervical vertebrae are shorter than that of others and have bifurcations.
The next category is the thoracic and is made of twelve thoracic vertebrae. Thoracic vertebrae are followed by lumbar region made up of 5 lumbar vertebrae. Spines of thoracic vertebrae are longer and are directed downwards while that of the lumbar vertebrae project towards the posterior region. the sacrum is present below the lumbar region and consists of five fused sacral vertebrae. The last category of spine is coccyx. It has four fused coccygeal vertebrae.
Answer:
A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support.

Answer:
A) Vascular cambium
Explanation:
(The vascular cambium is a type of cell found in lateral (not apical) meristems and is involved in secondary (not primary) growth.)
Answer: The DNA repair process was called recombination repair.
Explanation: A sister or homologous chromatide is used to generate recombination and be repaired in this sort of cases.
