What is double fertilisation

Biology
2 answers:
horsena [70]3 years ago
7 0

Double fertilization is a complex fertilization mechanism of flowering plants. This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes ( It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.

Hope this helps!

What is the pathway of information through a neuron?
garik1379 [7]

Answer:

The pathway of information through the neuron is based in the connection of axons with other neurons, favoring the conduction of information from one place to another of the nervous system. The way in which a neuron communicates with another, with a receptor or an effector is called synapse.

Explanation:

Neurons are the specialized cells that allow the function of the nervous system, given by the transmission of information in the form of nerve impulses. The way in which information is transmitted by neurons depends on the connection that exists between neurons, by their axons and dendrites, or between enurons and specialized structures such as receptors and effectors.

When a stimulus reaches a receptor, it connects with the neuron that carries the information by afferent pathway to the central nervous system. Once the information is processed, a response is elaborated that travels through the neurons by efferent pathway to an effector cell.

Synapses are simply the connection that exists between neurons, through their axons, or from these cells to the receptor or effector structures. Synapses are located between one neuronal axon and another, or between axons and receptors or effectors, and occur through electrical signals or chemical mediators called neurotransmitters.

aliina [53]

Answer:

Which type of selection tends to increase genetic variation? A. Disruptive selection B. Directional selection C. Stabilizing selection

The Answer is option A (Disruptive selection)

Explanation:

Selection can either shift the mean value of a trait, reduce the trait's variation, or increase its variation.

Genetic variation which allows natural selection to increase or decrease frequency of alleles already in the population is a source of phenotypic variation as it refers to differences in all the hereditary information of members of the same species.

Disruptive Selection is important in maintaining variation and initiating speciation as it Increases Variation by favoring alleles corresponding to more extreme phenotypes. But for it to occur, the mean phenotype has to experience the lowest fitness. Disruptive selection affects the frequency distributions of alleles and genotypes within a population.

Disruptive selection is based on the variance of a trait in a population as it increases genetic variance by equalizing the frequencies of existing alleles at polymorphic loci (a genetic loci with two or more alleles). Disruptive selection maintains and may even increase variation in natural populations by favoring extreme phenotypes, individuals with extreme values for a trait have greater reproductive success than individuals with intermediate values.
