Explanation:
The best explanation for the presence of vestigial pelvis and femurs in some snake and whale species is
Answer:
a common ancestor that used these structures to perform one or more specific functions
Explanation:
A vestigial structure is an organ that has no obvious function in an organism, but it has been used by a past ancestor to perform one or more specific functions. Thus, vestigial structures have been retained in the course of evolution, but they lost their ancestral functions. Vestigial structures/organs can be detrimental for the organism because it is required energy to maintain them and they may suffer diseases (e.g., cancer). Some well-known examples of vestigial organs/structures include, among others, the wings of ostriches and cormorants, the human appendix, etc.

The bone cell of a goat contains 60 chromosomes.How many chromosomes will be in each daughter cell after mitosis
The bone cell of a goat contains 60 chromosomes, so there will be 60 chromosomes in each daughter cell after mitosis, as mitosis is the cell division that will produce daughter cells with the same genetic contents.
What exactly is mitotic cell division?The cell divides during mitosis, and the daughter cells formed have the same genetic content as the parents, here, two daughter cells are formed, with the bone cell having genetic content same as original bone cell. Because the duplicated chromosomes are separated equally by the spindle fibers without crossing over or recombination, 60 chromosomes will form that is the same number of chromosomes after mitosis.
Hence, the bone cell of a goat contains 60 chromosomes, so there will be 60 chromosomes in each daughter cell after mitosis, as mitosis is the cell division that will produce daughter cells with the same genetic contents.

Describe the Lysogenic cycle.
No dam links
Answer:
Here ya go
Explanation:
The lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In some interactions between lysogenic phages and bacteria, the lysogenic conversion may occur, which can also be called phage conversion.

What are the five main phases of the cell cycle? What are the main events in each?
Answer:
In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.
Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

Pioneer species such as lichen and moss inhabit an area after a major disturbance such as a volcanic eruption. Over time, other species are found in the disturbed area and the number of pioneer species decreases. Why does the number of pioneer species decrease? The amount of available sunlight is reduced. The pioneer species can no longer thrive. ⊝ The area has more soil to support complex plants. The competition increases between organisms. ⊝ The area is more susceptible to the wind. Seeds are captured in the pioneer plants and germinate at a higher rate. ⊝ The temperature is not as extreme as it was following the disturbance. Fewer of the pioneer species reproduce. ⊝ CLEAR ALL ❮ PREVIOUS ... 3 4 5 6 7 8 9 10 11 12
Answer:
The competition increases between organisms.
Explanation:
Primary succession occurs after a disturbance or disaster that leaves open spaces with no living organisms. These new open areas are the case, for instance, of a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. No previous species inhabiting this area are left.
These scenarios allow new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the ground and making it better with time. Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources. Habitat modification keeps on going while new species establish. They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. This sequence continues until there is not more facilitation, and the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
how do mutations lead to a variation of traits with a population if organisms?
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.
Explain why ecologists think the focus of conservation efforts should be ecosystems, not individual species?
It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.

The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.
Answer:
4
Explanation:
The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection according to Darwin's (and Wallace's) theory of evolution.
Natural selectionNatural selection is the process through which populations of living organisms adapt and change.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation.Thus, we can conclude that The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.
