Fertilization between the haploid gametes forms a diploid zygote. The zygote will undergo many rounds of mitosis and give rise to a diploid multicellular plant called a sporophyte. ... The spores will then develop into the multicellular gametophytes.

SPINDLE FIBERS
In Mitosis, Spindle Fibres form at opposite poles of the cell and meet at the equator. Collectively, they form a spindle-shaped structure which attach to Centromeres.
CENTROSOMES
The organelle located near the nucleus in the cytoplasm,
composed of 2 centrioles that divides during S Phase
Centrioles are surrounded by a mass of proteins (Pericentriolar Material (PCM))
Migrates to opposite poles of the cell during mitosis
Involved in the creation of spindle fibres
CHROMOSOMES
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Centromeres
The constricted region joining the two sister chromatids that make up an X-shaped chromosome. It also serves as the point of attachment for spindle fibers when the spindle fibers are pulling the chromosomes toward the centrioles (situated on opposite poles in a cell) prior to cytokinesis.
Answer: low rate
Explanation:
Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.
Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.:
Answer:
Lack of predators
Explanation:
The carrying capacity is the amount of organisms that the habitat is able to support. Invasive species compete with native species for limited resources including food, niche, etc. This phenomenon may have important negative effects on the survival of native species, even it may lead to the extinction if the invasive species is successful
Answer:
The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.
Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.
