Answer:
New species can appear gradually through small changes in an ancestral species.
Explanation:
The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.
The purpose of meiosis<span> is to reduce the normal diploid cells to haploid cells, called gametes.

Conventional in vitro fertilization refers to the development of embryos in the laboratory conditions, intracytoplasmic sperm injection refers to the add of sperm cytoplasm to the egg cell, laser-assisted hatching helps the egg cell to reach the zona pellucida while artificial insemination helps to development of a zygote by artificial fertilization.
<h3>What does assisted reproductive technology mean?</h3>
The medical term assisted reproductive technology makes reference to all methods and strategies aimed at enhancing or helping the development of the zygote or embryo after fertilization, which may be in vitro fertilization (laboratory conditions) or in vivo conditions into the reproductive system.
Therefore, with this data, we can see that assisted reproductive technologies refer to a broad differential category of strategies and methods aimed at helping with the development of zygotes and embryos in the reproductive system of a woman or in the lab conditions.

Answer:
C!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
3, 5, 1, 4, 2.
Explanation:
Neurons are the structural and the functional unit of the nervous system. Two main types of neurons on the basis of their function are sensory neurons and motor neurons.
The motor control in order body occurs in a sequential step. The motor program is selected by the pre motor cortex. This neuron is further stimulated by basal nuclei of the thalamus. This further stimulate the lower motor neuron. This causes the contraction in the skeletal muscle. This information is further move to cerebellum if movement is required.
Thus, the correct order is 3, 5, 1, 4, 2.
