A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimated population of 11,500 individuals on a wildlife preserve of 115 hectares. (One hectare is equal to 2.47 acres of land.) The scientist calculates the carrying capacity at 14,600 individuals.
Part A
Factoring a death rate from natural causes and predation, the beetle population increases approximately 5% each year. Use the Table button to create a table showing the estimated population for each year, starting with the current population and stopping when you’ve reached or exceeded the carrying capacity.
Answer/Explanation:
Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:
Year Calculation Est. Population
1st yr (current yr) 11,500
2nd yr 11,500*105% 12,075
3rd yr 12,075*105% 12,679
4th yr 12,679*105% 13,313
5th yr 13,313*105% 13,979
6th yr 13,979*105% 14,678
The above is how the table would like showing the estimated population for each year.
Answer:
To find the population of beetles each year, we multiply the previous year’s population by 105% (100% + 5%).
Year Population
1 11,500
2 12,075
3 12,679
4 13,313
5 13,978
6 14,677

Populations depend on and _____________________ with each other.
Answer:
The correct answer is "compete".
Explanation:
The missing options of this question are:
compete
fight
work
The correct answer is "compete".
Populations are defined as groups of living beings that live in a certain location. Usually, the term population is used to describe groups of persons, but it applies for groups of animals and plants as well. Populations depend on an compete with each other, either for resources, new lands or because they are natural enemies. Populations are constantly competing, which is the base of natural selection.
Answer:
Populations depend on and compete with each other.
Explanation:
The competition between organisms and species is an interaction where both parties are harmed either by an external factor such as territory, water, food ...
Studies show that competition regulates demographic rates between species in an ecosystem.
And according to evolutionary theory, this competition for an external or internal factor is important for natural selection.
Consequently, competition requires species to adapt to change to survive or they will be in danger of disappearing.

What would happen to the cell or organism if the protein is changed as a result of the mRNA being produced incorrectly?
A. The cell or organism will definitely have changes
B.The cell or organism may or may not have any noticeable changes
C.The cell or organisms life expectancy will drastically decrease
D.The cell or organism will not have any changes
Answer:
B. The cell or organism may or may not have any noticeable changes.
Explanation:
Some mutations can cause small changes, if any, such as different colored hair, or they can cause massive changes such as uncontrollable cell division, AKA cancer. Mutations are random so nothing is definite.
The mutation is the alteration in the nucleotide sequence or the proteins. If mRNA is incorrectly produced and alters the protein then there may be or may not be any noticeable changes. Thus, option B is correct.
What is mutation?The mutation is the state in which the bases or the amino acids coding the proteins during the mRNA translation are altered due to mutagens, genetic error, etc.
The mutation in the protein may or may not cause any change as some changes are not noticeable and very small, while some alterations may be big and dangerous.
Therefore, the mutation in the proteins may or may not be noticeable.

What is the definition of photosynthesis
Answer:the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

How does a scientist come up with the theory?
Answer: By reviewing extensive amounts of evidence that support a scientific explanation of phenomena. For example, Darwin's Theory of Evolution is supported because of the evidence and research of the finches in the galapagos islands that make sense in a scientific world that evolution does indeed exist.
Explanation:
what did scientists like Darwin use to group species before DNA? two sentences, please!
They used to group organisms by watching their physical characteristics. For example animals with spines are grouped into vertibrates and organisms without spine are grouped into invertebrates . They also group organisms based on habitatats ( where the organisms live) . For example marine animals live in water and terrestrial organisms live in land. They grouped organisms based on their feeding behaviour. For example producers produce their own food.

According to an answer from another and a bit of my own research;
A decomposer is exactly what it sounds like, an organism that decomposes something and feeds off of it. You can eliminate the answers "Owl" and "Hawk" from a first glance as they are both consumers. Looking at it again, an "Ant" is not a decomposer, but rather, a consumer just like your other two options. This leaves "Fungus", something that decomposes it's food.

Which of the following is a valid benefit of flattening an image in Photoshop?
A. Flattened images are smaller
B.Flattened images allow for copyright protection
C. Flattened images have a higher resolution
D.Flattened images are printer compatible
Answer:
A.
I hope this helps!
Flattening an image in Photoshop has multiple benefits, including smaller file sizes, increased apparent resolution, and printer compatibility.
Explanation:A valid benefit of flattening an image in Photoshop is that flattened images are smaller. When you flatten an image, it combines all the layers into a single layer, which reduces the file size. This is especially useful when sharing or uploading images online. However, it's important to note that flattening an image also removes the ability to edit individual layers.
While flattened images do not directly increase resolution, they can appear to have a higher resolution because of the way the pixels are consolidated. Finally, flattened images are generally printer compatible because they eliminate any transparency or layer effects that may not translate well to print.

The average temperature of an area can give a rough estimate of time since death, but other factors need to be considered for an accurate calculation. Consulting a forensic expert is essential.
Explanation:The average temperature of a given area can provide some insights into the time of death of a person. However, it is important to note that estimating the postmortem interval (time since death) based solely on temperature can be challenging due to many factors. In this case, the average temperature of 70°F in the area can give a rough estimate, but it would be necessary to consider other factors such as body temperature at the time of death, insulation, clothing, body composition, and external factors like shade or direct sunlight.

greater than 39m
Answer:
53%
Explanation:
The correct answer would be 53%
Considering the Indo-Pacific Ocean alone, the total percentage of coral species that can grow at a depth greater than 39 m starts from 40 - 59 bar till the last bar. The respective percentage in each bar is calculated below;
40 - 59 = 40
60 - 79 = 7
80 - 99 = 4
100 - 119 = 1
120+ = 1
Hence, the percentage of coral species in the Indo-Pacific Ocean that can grow at a depth greater than 39 m = 40 + 7+ 4 + 1 + 1 = 53%
The Diagram shows part of a prairie food web. Which species in the food web would be subject to the greatest bio-magnification of pesticides applied to the grasses?
A.) Deer
B.) Grasses
C.)Hawks
In a food web, bio-magnification of pesticides happens at each successive level of the food chain. In the given prairie food web, the Hawks would be subject to the greatest bio-magnification as they are the top-level predators feeding on deer, which feed on pesticide-applied grasses.
Explanation:In this food web, the species which would be subject to the greatest bio-magnification of pesticides applied on the grasses would be the Hawks (option C). This is because of a process known as bio-magnification, which is the increase in concentration of a substance, such as pesticides, in an organism at each successive level in the food chain.
Here, the pesticides are first taken up by the grasses. They are then transferred to the Deer when the Deer feed on the grasses. When Hawks subsequently feed on the Deer, the concentration of pesticides further increases. This is why Hawks, being apex predators in this web, accumulate the highest concentration of pesticides.
