The correct answer is -
1. capture
2. the giant impact hypothesis
3. electromagnetic spectrum
4. cold
5. 14
Explanation:
Capture hypothesis is presented by the Urey and was dominant up to the 60s which states that the Moon was an asteroid-like wandering structure that formed somewhere far in the solar system and was captured by Earth's gravity while it was wandering.
The most dominant and popular theory for the origin of the moon is the giant impact hypothesis says that it is formed from the debris left after the collision of the earth and Theia a Mars-sized body.
Telescopes are tools engineered for collecting light from any part of the electromagnetic spectrum.
Scientists estimated that the age of the whole universe to be nearly 14 billion years with the help of Hubble's pictures and pictures from the Probe of Wilkinson

6. The moon's mass is much lower than the earth's; therefore, its gravity isn't strong enough to hold an atmosphere. This lack of an atmosphere and the moon's small size allowed it to become cool enough to the point at which it completely solidified. Thus, the moon doesn't have any plate tectonic activity.
The basic process of disease transmission involves:_________
a. a source, a mode of transmission, and a susceptible host.
b. a highly virulent pathogen and a breakdown in infection control techniques.
c. a source, a weakened host immune system, and delayed recognition of the infection.
d. poor hand washing, a susceptible host, and inappropriate antibiotic us
Answer:
The basic process of disease transmission involves:_________
a. a source, a mode of transmission, and a susceptible host.
Explanation:
The sources of a disease include individuals, animals, and the environment. Transmission occurs when there is a transfer of the pathogen from one individual or source to another. Disease transmission cannot be complete without the host. As always, a successful transmission happens when the host becomes susceptible to the disease, which will weaken its immune system.
If you are told that the average GPA of students in 2015 at a public university was 3.27. A survey of students in this university that included 203 participants in the Spring semester of 2017 yielded an an average GPA of 3.35. From these information you discern that:______.
Answer:
Sample mean = 3.35
Population mean = 3.27
Explanation:
Given that:
Average GPA of students in university for the year 2015 = 3.27
Average GPA of 207 student of the same University in 2017 = 3.35
Using the data given above, the average GPA obtained in 2015 as the characteristic of being a PARAMETER. As it made use of all observations in other to arrive at the mean value of 3.27
The 2017 average GPA determined made use of only a subset of all students. In statistics, statistical values obtained from only a subset of the population observation is called STATISTIC.
Hence, it could be discerned that:
Sample mean = 3.35
Population mean = 3.27

Introduction: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The results of this program are shown in the following table.
1. Describe what happened to the deer and wolf populations between 1971 and 1980. How did the number of wolves affect the number of deer?
2.What do you think would have happened to the deer on the island had wolves NOT been introduced? How do you predict this would affect the ecosystem?
3. Look at the number of deer in “predation” and “starvation” columns. What conclusions can you draw about the introduction of the wolves on these values?
1. Between 1971 and 1980, the deer population initially decreased significantly after the introduction of wolves. In 1971, there were 2000 deer, but by 1974, the population had dropped to 450.
This decline in deer population can be attributed to predation by the introduced wolves. As the number of wolves increased over the years (from 10 in 1971 to 50 in 1980), the deer population continued to fluctuate but remained relatively stable, ranging from 100 to 200 individuals.
2. If wolves had not been introduced, it is likely that the deer population would have experienced overgrazing and potential mass starvation. With limited food supply on the island, the deer population would have continued to grow and surpass the carrying capacity of the ecosystem.
This would have led to increased competition for resources, depletion of food sources, and eventual population decline due to starvation. Additionally, the absence of natural predators would have allowed weaker members of the deer herd to survive and reproduce, potentially leading to a decrease in overall deer quality and health.
3. Looking at the number of deer in the "predation" and "starvation" columns, it can be inferred that the introduction of wolves had a significant impact on reducing the number of deer deaths due to starvation.
As the number of wolves increased, the number of deer deaths from starvation decreased. This indicates that the predation by wolves helped control the deer population and prevented overgrazing, leading to a more balanced ecosystem with a sustainable deer population size.
The presence of wolves acted as a natural regulatory mechanism, eliminating weaker deer individuals and maintaining a healthier deer population overall.

What are the three steps of the translation process?
Answer:
What are the three stages of translation?
Translation of an mRNA molecule occurs in three stages: initiation, elongation, and termination.
Initiation: The ribosome assembles around the target mRNA and the start codon 5’ AUG is recognized.
Elongation: The tRNA transfers an amino acid to the tRNA bound to the next codon, forming a peptide bond between the two amino acids. The ribosome then translocates to the next codon to continue the process, creating an amino acid chain in the direction from the N terminal to the C terminal.
Termination: When a stop codon is recognized, the elongation of amino acid chain terminates. The ribosome then folds the polypeptide into its final structure.

The air in the thermosphere becomes thinner and thinner until it fades into space. true or false
Answer: hope this helps
Explanation: The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.
The air in the atmosphere becomes thinner and thinner until it fades into the space because thermosphere has less air pressure and gases.
What happens in thermosphere ?A layer (or layers) of gases that surround a planet and are held in place by the gravity of the planetary body is known as an atmosphere.
The air at the bottom of the atmosphere is under much more weight than the air nearer the top, like the acrobat at the bottom of a stack of acrobats. It follows that the air closer to the Earth's surface is compressed by the air above it and is subsequently denser. The air gets thinner as you go higher in the atmosphere.
Therefore, as we go further into the space the thermosphere becomes thinner and thinner until it fades into space.

Hello help plz :)!!!!!!!!
This increase in the plant cell as water moves in keeping the plant erect but prevents it from bursting. A. Exocytosis
B. Gradients C. Turgid pressure D. Diffusion
Answer:
The change is caused by C. Turgid pressure
Explanation:
Turgor pressure, is exerted internally by the plants own cells. The water in the plant moves from areas of high concentration to areas of low concentration along a concentration gradient.
The cells contain large organelles called vacuoles, which are filled with water, salts and other substances contained in cell sap. The large vacuole takes up most of the cell, and pushes against the cell walls. This exerted pressure keeps the cell's shape, and ensure that the tissues stay upright.

The oceanic water is salty as they have salts mixed in it.
The correct option is C.
70% of the earth is made up of water and most of the water is salty due to the leaching process of salt during the formation of the earth.
In that time rain pours on earth for millions of years which digested the rock and dissolves its nutrient.
Hence, the correct option is C that is warm water with high salt content. The salt concentration remains the same throughout the water.

Why couldn’t the amoeba taste PTC paper?
Many species of bacteria grow in the mouths of animals and can form biofilms on teeth (plaque). Within plaque, the outer layers contain high levels of oxygen and the layers closest to the tooth contain low levels of oxygen. The surface of the tooth is covered in a hard layer of enamel, which can be dissolved under acidic conditions. When the enamel breaks down, the bacteria in plaque can extract nutrients from the tooth and cause cavities. Certain types of bacteria (e.g., Streptococcus mutans) thrive in the innermost anaerobic layers of the plaque and are associated with cavities. Other types of bacteria (Streptococcus sanguinis) compete with S. mutans but are unable to thrive in acidic environments. Identify the biochemical pathway mutans uses for metabolizing sugar and describe how the pathway contributes to the low pH in the inner layers of plaque. Normal tooth brushing effectively removes much of the plaque from the flat surfaces of teeth but cannot reach the surfaces between teeth. Many commercial toothpastes contain alkaline components, which raise the pH of the mouth. Predict how the population sizes of mutans AND S. sanguinis in the bacterial community on the plaque between the teeth are likely to change when these toothpastes are used.
Answer:
-->The biochemical pathway is fermentation.
--> The population of Streptococcus sanguinis will increase while the population of Streptococcus mutans will decrease.
Explanation:
Biofilms are aggregated microorganism communities which are found attached to dental surfaces. Many species of bacteria such as the Streptococcus mutans and streptococcus sanguinis grow in the mouth of animals and form biofilms, also called dental plaque.
The S. mutans thrive in the Innermost anaerobic layer of the plaque due to their ability to metabolize sugar through the process of FERMENTATION. Because there is absence of oxygen in the Innermost layer of the plaque, glucose is transformed to lactic acid which lowers the pH of the inner layer of the plaque.
The use of commercial toothpaste can help remove or reduce plaques for the flat surfaces of the teeth. When alkaline toothpaste are used, the population of S. sanguinis will increase since they are able to survive in alkaline ( high pH) environment. The population of S. mutans will decrease since they can't survive in alkaline environment
