Coral in the ocean grows by budding, where the new organism grows out of the old one by mitosis. this form of replication is an example of asexual reproduction.
Asexual reproduction is a type of reproduction that does not involve gamete fusion or changes in the number of chromosomes. Progeny resulting from asexual reproduction from unicellular or multicellular organisms inherits the complete set of genes from a single parent.
Asexual reproduction is a type of reproduction in which a single parent gives birth to new offspring. Newly produced individuals are genetically and physically identical. That is, they are clones of their parents. Asexual reproduction is observed in both multicellular and unicellular organisms.

Zebras and other grazers band together when grazing. which type of behavior is this?
The behavior of zebras and other grazers banding together while grazing indicates their social behavior to protect themselves and their group mates from predators.
Grazing: It is a process in which herbivores roam from one place to another in search of grass, small plants, etc which are the main source of food for them. It involves forage search, selection of forage, and eating the selected forage. Different animals differ in the type and method of searching and eating forage. This different grazing behavior makes them different from one another.
Although, one common thing which is observed in these grazing animals is the practice of grazing in bands or groups. This is generally noticed in the area where they have more danger from predators so they practice this banding method as a protective measure because predators find it difficult to attack groups and they get less chance to kill a lone individual.

What describes the relationship between a dominant and recessive allele?
Answer:
Dominant refers to the relationship between two versions of a gene.
Explanation:
Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
In the α helices of transmembrane proteins, the hydrophobic side chains face which direction?
In the α helices of transmembrane proteins, the hydrophobic side chains face the outside of the membrane-spanning helix.
Transmembrane proteins are a type of integral membrane protein that spreads throughout the cell membrane. Many transmembrane proteins act as gates that allow the transport of certain substances across the membrane.
Transmembrane proteins basically act as gates or docking sites that allow or prevent substances from crossing the cell membrane.

How do xenoturbellida relate to hemichordates and nonvertebrate chordates?
The deuterostome group's gene arrangement in the mitochondrial genome of Xenoturbella bocki is remarkably close to that of the chordates and hemichordates and hence to the ancestor deuterostome gene order. Inversion and breakpoint studies particularly point to a similarity to the hemichordates.
Previous morphological investigations imply that Xenoturbella could be classified as a bivalve mollusc, a basal bilaterian, a turbellarian flatworm, a sister group to the echinoderms(nonvertebrate), or a hemichordate. Recent genetic analyses that focus mostly on nuclear genes appear to favour the Ambulacraria (echinoderms + hemichordates). In contrast, a basal deuterostome location is supported by mitochondrial sequences.

The continuous, low-level extinction of species is referred to as ___ extinction.
The continuous, low-level extinction of species is referred to as mass extinction.
A widespread and quick decline in the diversity of life on Earth is known as an extinction event. A sudden shift in the diversity and abundance of multicellular creatures serves as a telltale sign of such an occurrence. It happens when the rate of diversification outpaces the rate of extinction.A mass extinction event occurs when a species disappears far more quickly than it is replaced. This is typically understood as the loss of almost 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.The Cretaceous-Paleogene extinction, sometimes known as the day the dinosaurs died, is the most well-known of all the mass extinction events.

State the shortest number of days it takes an Earth observer to see the same phase of the Moon twice.
Answer:29.5 days
Explanation:
It takes 29.5 days for observers from earth to look at the moon phase twice.
What are the phases of the moon?The fact that the moon orbits the earth every 27.3 days and the phases cycle once every 29.5 days might be perplexing. The rotation of the Earth around the Sun is to blame for this.
Our Moon completes one full orbit of the Earth in 27 days, 7 hours, and 43 minutes. The distance between our Moon and far-off "fixed" stars serves as the basis for measuring what is known as the sidereal month.
However, one cycle of phases on our Moon lasts for around 29.5 days (from the new Moon to the new Moon).

Ineffective Sewage Systems:
Many of the sewer systems that are still in use today date from the immediate post-World War II period. The majority of these systems struggle even without the additional strain of intense rain or storms because their infrastructure is outdated and deteriorated at this time.
Insufficient Drainage:
Less green space is available in metropolitan areas due to rising urbanization and the constant construction of new buildings. Urbanization depletes the natural drainage systems that are supported by vegetation and soil.

Condensation of nucleoside triphosphate with a hexose 1 phosphate to form a sugar nucleotide has a small free energy change and this condensation is irreversible because the reaction releases PPi, which is rapidly hydrolyzed by inorganic pyrophosphatase (highly exergonic).
PPi is kept low, making first step favorable & ensures results favorable energy change (exergonic) therefore formation of sugar nucleotides drives the reaction forward / is metabolically irreversible.

This given statement, as a result of the Ordovician Mass Extinction, that many reef-building organisms went extinct, but reefs recovered in only a few hundred thousand years is false.
What happened in the Ordovician mass extinction?
The Ordovician-Silurian extinction, which occurred 443 million years ago, resulted in the destruction of 85% of all species on Earth. The many marine species living in warm, shallow coastal waters were severely harmed, most likely as a result of global cooling and declining sea levels. There were many different types of animals affected by this extinction, including brachiopods, corals, trilobites, echinoderms, and mollusks. Species that were unique to the eastern United States were particularly vulnerable.
The Late Ordovician glacier, which quickly extended over Gondwana at the beginning of the Hirnantian and changed the Earth's temperature from a greenhouse to an icehouse, is widely blamed for this extinction pulse.

If you suspect your culture of bacteria has 23 x 106 cells per mL, what would you want the final dilution to be in order to end up with 96 colonies of bacteria on a petri dish
The dilution factor in order to end up with 96 colonies of bacteria is 0.23 × [tex]10^6[/tex] .
For calculating the colony forming unit bacteria;
Colony-forming unit (CFU or cfu) is a measurement of live bacterial or fungi cells and is used to calculate the colony-forming unit of bacteria. CFU counts only viable cells as opposed to direct microscopic counts, which count all cells, both living and dead, using a hemocytometer. Colony-forming units per milliliter (CFU/mL) for liquids and colony-forming units per gram (CFU/g) for solids are used to indicate the results for convenience. The miles and Misra method can be used to compute CFU, which is helpful for assessing the microbiological load and severity of illness in blood and other samples.
∴ cfu/ml = (no. of colonies x dilution factor) / volume of culture plate
23 x [tex]10^6[/tex] cells per mL = 96 × dilution factor
Dilution factor = 23 ×[tex]10^6[/tex] / 96
Dilution factor = 0.23 × [tex]10^6[/tex]

The correct molar coefficients will be 1, 3, 3, and 1 respectively.
Balancing chemical equationsA balanced chemical equation is an equation that obeys the law of conservation of atoms.
In other words, the number of atoms of the elements in the reactants must be equal to the number of atoms of the same elements in the products.
Hence in the reaction with the chemical equation: [tex](NH_4)_3PO_4 +HCI --- > NH_4Cl +H_3PO_4[/tex]
The number of atoms of N, H, P, O, and Cl in the reactants must be the same as in the products.
