When there is no pattern to a
population's growth, it is known as
A. irregular
B. stable
C. irruptive
D. cyclical
When there is no pattern to a population's growth, it is known as stable. The correct option is B.
What is population growth?The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.
The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.
When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.
Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.
Thus, the correct option is B.

Explain the process of when a wave occurs.
Science PLZ HELP
Answer:
energy passing through the water, causing it to move in a circular motion. When a wave encounters a surface object, the object appears to lurch forward and upward with the wave, but then falls down and back in an orbital rotation as the wave continues by, ending up in the same position as before the wave came by.
Explanation:
Answer:
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. The gravitational pull of the sun and moon on the earth also causes waves.
In the human body, organ-systems interact with each other to maintain homeostasis. Using the diagram below, explain how this system interacts with another in the body to maintain homeostasis?
Answer:
D
Explanation:
Im pretty sure tell me if im right
Homeostasis is a regulating process of the body in response to external environments, digestive system provides glucose for cellular respiration.
How do organ systems interact to maintain homeostasis?Organ systems in our body are regulated with each other and these interactions maintain homeostasis.
The respiratory system interacts with the circulatory system for gaseous exchange and the excretory system depends on the circulatory system for blood filtration, and the nervous system regulates the system through the brain.
Homeostasis is necessary because the external environment can change anytime, and the digestive system maintains food conditions according to the body's needs.
Therefore digestive system maintains homeostasis by providing glucose for cellular respiration.

A teacher asks students to make a model of a transform plate boundary. The students use blocks to represent tectonic plates and slide the blocks past each other in the directions of the arrows as shown.
Answer:
The model is right.
Explanation:
The model made by the students about transform plate boundary is right because in the transform plate boundary, the tectonic plates moves horizontally by rubbing each other. As the tectonic plates rub against each other, huge stresses are created that can cause breaking the portions of the rock that results in earthquakes in that region. The area or regions where these breaking of rocks occur is known as faults. San Andreas Fault in California is the example of transform plate boundary.

What structures allow each protist to move?
Amoeba:
Euglena:
Paramecium:
Amoeba moves using pseudopodia.
Euglena moves using flagellum.
Paramecium moves using cilia.
What are the structures that allow the movement in different protists?
Pseudopodia, or protruding portions, are used by amoebas to move. Its meaning is "false feet." These are membrane elongations of the cell. With its pseudopod, an amoeba can reach out and grab a surface, using it to propel itself forward.Flagellums (plural flagella), a long whip-like structure that functions as a little motor, help euglena move. On the anterior (front) end, the flagellum spins in order to propel the cell through the water.Cilia have the ability to move in unison to advance a Paramecium. When a barrier is reached, the cilia travel in the opposite direction, somewhat reversing the Paramecium's forward motion.

The four main forces that drive evolution are mutation, natural selection, genetic drift, and gene flow. All of these forces can cause a change in what?
Answer:
Allele frequencies
Explanation:
The only component that is transmitted from generation to generation is the genetic material (genes), the fact that an individual leaves more descendants implies that their genetic variants (alleles) will be more represented in the next generation. The frequencies of the different alleles will change from one generation to another, and this change will be irreversible when the set of genes in the population is considered, since it is highly unlikely that a previous configuration will be returned in all gene variants. Hence, from a population point of view, evolution is ultimately a cumulative and irreversible change in the proportions of different gene variants in populations. The agents that change the allele (or gene) frequencies of populations, that is, factors of evolution, are mutation, genetic drift, migration, and natural selection. Mutation is a factor that increases genetic diversity. Natural selection is the process by which the gene frequencies involved with certain traits vary from generation to generation, since some variants of the trait have a greater capacity than others to survive and produce offspring. The mutation rate of a gene or DNA sequence is the frequency at which new mutations occur in that gene or sequence in each generation. In each generation there is a gene raffle during the transmission of gametes from parents to children which is known as genetic drift. In the absence of gene flow, gene drift will also lead to local differences in allele frequencies.

Why does DNA need to be replicated
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Answer:
DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
Explanation:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes.
DNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

A moth's color is controlled by two alleles, G and g, at a single locus. G (gray) is dominant to g (white). A large population of moths was studied, and the frequency of the G allele in the population over time was documented, as shown in the figure below. In 1980 a random sample of 2,000 pupae was collected and moths were allowed to emerge. Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what percentage of the gray moths that emerged in 1980 was heterozygous? (The Answer is 67%, can you please explain why it's 67%? thank you!!)
Answer:
67%
Explanation:
When taking random samples from a population, the observed numbers are not always as the expected ones. The difference is by chance, instead of 50% heter0zyg0us, the sample included 67%.
--------------------------
Available data:
- Moths' color ⇒ diallelic gene
G allele → dominant → Codes for greyg allele → recessive → Codes for white- f(G) 1960 = 0.8
- f(G) 1965 = 0.7
- f(G) 1970 = 0.6
- f(G) 1975 and 1980 = 0.5
- 1980 ⇒ N = 2000 pupae
- Population in H-W equilibrium
Hardy-Weinberr equilibrium,
Assuming a diallelic gene, p and q are the allelic frequencies in a locus and represent the allelic d0minant or recessive forms. The gen0typic frequencies after one generation are p² (H0m0zyg0us d0minant), 2pq (Heter0zyg0us), q² (H0m0zyg0us recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation.When adding the allelic frequencies of a population in H-W equilibrium, the result should be 1, this is p + q = 1.In the same way, when adding the genotypic frequencies, the result should also equal 1, this is p²+ 2pq + q² = 1In this problem we assume that the population is under H-W equilibrium, and we know that p = 0.5.
Considering that p + q = 1, then by clearing the equation, we get the value of q = 0.5
Finally, we know that the genotypic frequency of the heter0zygous genotype is 2pq, so,
F(Gg) = 2pq = 2 x 0.5 x 0.5 = 0.5 = 50%
Now, among the options in the problem, there is not 50% but others. One of them, and the closest to 50%, is 67%.
The chart reflects that through the years, the moth's populations stabilized. Both alleles were favored, and their frequencies got to be equal to each other -0.5-. So there is a high probability of getting heter0zyg0us individuals in the population -50%-, more than any of the h0mzyg0us ones -25%-.
However, in a natural population, the amount of h0m0zyg0us and heter0zygous individuals observed is not always the same as the expected ones. This fact happens especially when there are random samples.
In this experiment, the researcher took 2000 pupae, but they did not know their genotype. They just took them randomly. Even though the population is in H-W equilibrium, when sampling, the researcher took more heter0zyg0us individuals than the expected ones. It does not mean that the population is not under H-W equilibrium. It just means that by chance, more heter0zyg0us were selected.
So what you need to do in these situations, is to analyze your problem and the provided information, and think about the most feasible answer.
In this case, the expected number is 50% heter0zyg0us. The closest option is 67% and the most feasible. So that would be the answer.
