which non-native species reached plague proportions but were finally brought under control in australia after the purposeful introduction of a disease affecting only that species
The non-native species that reached plague proportions but were finally brought under control in Australia after the purposeful introduction of a disease affecting only that species are rabbits.
Non-native species are plant and animal species that do not normally occur in a particular region or country but are introduced through human activities. Non-native species, often known as invasive species, can pose significant problems to ecosystems, native species, and humans.
They might also spread diseases that are harmful to native species and humans, disturb natural habitats, and cause problems in the food chain. They can be introduced to new regions by a variety of methods, including unintentionally or intentionally, by transportation, and by trade.
Here are the measures to control invasive species:
Mechanical control measures: It involves physically removing invasive species from an ecosystem.
Chemical control measures: Chemicals can be used to kill invasive species, and this method has been demonstrated to be very successful in certain circumstances.
Biological control measures: Biological control methods use predators, parasites, and diseases that are native to the invaded ecosystem to manage invasive species.
As a result, in the 20th century, the myxoma virus was purposefully released into the rabbit population, resulting in a significant decline in the rabbit population.
In Australia, rabbits were introduced as game animals in the 19th century. After they established, they grew out of control and caused significant harm to native wildlife and ecosystems.

a genotype resulting from the inheritance of the same alleles from your parents is called___
Answer:

Explanation:
collection of codons of mrna, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis called____
The collection of codons of mRNA, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis, is called the genetic code.
The genetic code is essentially a set of rules that specifies how the information encoded in DNA is translated into proteins. The code consists of 64 possible codons, each of which codes for one of the 20 amino acids used to make proteins.
The genetic code is highly conserved, meaning that it is virtually the same in all living organisms, from bacteria to humans. This universality of the genetic code is what allows scientists to transfer genetic material between different species and even kingdoms of life.
The genetic code is read by the ribosome, a complex molecular machine that translates the mRNA sequence into a specific sequence of amino acids that make up the protein. The process of protein synthesis is highly regulated and controlled, and any errors in the genetic code can result in serious consequences, such as genetic disorders or diseases.

there is some evidence that pharyngeal slits occur in certain species of echinoderms that appear early in the fossil record. if confirmed, what do these data suggest?
a. Echinoderms are chordates b. Some lineages of echinoderms are more closely related to chordates than others C.Pharyngeal slits should not be used as a tralt in phylogenetics d. Pharyngeal slits were present in the earliest echinoderms and lost later
If confirmed, the data suggest that Pharyngeal slits were present in the earliest echinoderms and lost later that is option D.
Deuterostomes have filter-feeding structures called pharyngeal slits. Pharyngeal slits are repeated openings that appear along the pharynx caudal to the mouth. They may transfer water in the mouth and out the pharyngeal slits while in this posture.
It is suggested that this is how pharyngeal slits originally assisted in filter-feeding, then subsequently, with the inclusion of gills along their walls, aided in breathing of aquatic chordates. These repetitive segments are governed by comparable developmental principles. Some hemichordate species have up to 200 gill slits. At the embryonic stages of tetrapod development, pharyngeal clefts that resemble gill slits are present.
The presence of pharyngeal arches and clefts in the growing human embryo's neck prompted Ernst Haeckel to suggest that "ontogeny recapitulates phylogeny"; while erroneous, this idea includes aspects of reality, as investigated by Stephen Jay Gould in Ontogeny and Phylogeny.

why is it necessary for chromosomes to duplicate before mitosis
Chromosome duplication before mitosis ensures that each daughter cell receives a full complement of genetic material, which is essential for proper cell function and division.
Before mitosis, chromosomes must duplicate in order to make sure that each daughter cell has the entire complement of genetic material. The duplicated chromosomes of the cell are split into two identical sets during mitosis, and each set is subsequently packaged into a brand-new nucleus in one of the daughter cells. In the absence of chromosome duplication before mitosis, the daughter cells would only get half of the genetic material required for optimal function.
Prior to mitosis, in the S phase of the cell cycle, chromosome duplication takes place. The DNA double helix unwinds during this stage, and the complementary strands are then employed as templates to create new DNA strands. This produces sister chromatids, which are two identical copies of each chromosome joined together by a unique structure known as the centromere.

Regarding the triplet code of DNA, which of the following sentences is true? 1 pike each DNA base codes for three amino acids there are three genes that code for a protein, each amino acid is coded for by three DNA bases each triplet codes for several amino acids
Answer:
The following sentence is true regarding the triplet code of DNA: Each amino acid is coded for by three DNA bases.
Explanation:
The genetic code is a set of rules that specify the correspondence between the three-letter codons in DNA and the twenty standard amino acids used to build proteins. Each codon codes for a single amino acid, except for three "stop" codons that signal the end of the protein sequence. Therefore, a sequence of three DNA bases (a triplet) corresponds to a specific amino acid, and the order of the triplets determines the order of amino acids in the protein sequence.
suppose that the regulators that control cyclin production are no longer produced. hypothesize two possible outcomes.
The regulators that control cyclin production are no longer produced. the two possible outcomes are Uncontrolled Cell Division and Cell Cycle Arrest
If regulators controlling cyclin production are no longer produced, two possible outcomes can be hypothesized:
1. Uncontrolled Cell Division: Cyclins are proteins that regulate the cell cycle by activating cyclin-dependent kinases (CDKs). Without proper regulation, cyclin levels may remain high, leading to continuous activation of CDKs. This could result in uncontrolled cell division, which may eventually lead to the formation of tumors and potentially cancer.
2. Cell Cycle Arrest: On the other hand, if cyclin levels are insufficient due to a lack of regulation, the cell cycle may become arrested at a specific phase. This could result in a decreased rate of cell division or even cell death, as the cell is unable to progress through the necessary stages for division.
In both scenarios, the disruption of cyclin regulation leads to significant consequences for cell growth and division, highlighting the importance of these regulators in maintaining proper cell cycle control.

However, the statement "have several vents" is not always true for shield volcanoes. While some shield volcanoes may have multiple vents, others may only have one central vent. Shield volcanoes are a type of volcano that have a broad, gently sloping shape resembling a shield or a flattened dome. They are formed from low-viscosity basaltic lava flows that spread out and accumulate over time, gradually building up the volcano's shape. Unlike other types of volcanoes, such as stratovolcanoes, shield volcanoes typically have non-explosive eruptions.

Answer:
Explanation:
To calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest, we need to use the following formula:
exercising - resting = increased blood flow
Substituting the given values, we get:
exercising - resting = increased blood flow
exercising - 1,200 cm³/minute = 4.CC
To solve for exercising, we need to isolate the variable on one side of the equation. Adding 1,200 cm³/minute to both sides, we get:
exercising - 1,200 cm³/minute + 1,200 cm³/minute = 4.CC + 1,200 cm³/minute
exercising = 4.CC + 1,200 cm³/minute
Therefore, the equation to calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest is:
exercising = 4.CC + 1,200 cm³/minute
