Answer:
B. The city park contains fewer natural predators of the red squirrel than the nature reserve.
Explanation:
When compared to a nature reserve a city park really doesn't have any predators apart from some cats or birds. There really isn't much that can challenge the squirrel in order for their numbers to go down. There is no threat from food shortages and no threat from being eaten by larger animals that could live there.
Answer:
the number of trees in the city park may be limited by humans
the nature reserve may be much larger in area than the city park.
increasing human activity in the city park may disrupt mating opportunities.
Explanation:
The carrying capacity of an ecosystem is usually determined by a combination of factors. Examples of such factors include the boundaries of the ecosystem, the climate, the type and amount of resources available, competition for those resources, and predation.
The researcher's experiment showed that, with respect to the red squirrel, the carrying capacity of the city park is much lower than that of the nature reserve. The possible explanations for this difference are numerous but might include statements like
the nature reserve may be much larger in area than the city park,
the number of trees in the city park may be limited by humans, or
increased human activity in the city park may disrupt mating opportunities.
Any or all of these factors may be responsible for the different carrying capacities of the two ecosystems.

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy
Answer:
the other 60% of energy is stored away for further use in the cell
Explanation:
i hope im right
In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.
How does ATP form from glucose?Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.
Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.
To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain. The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .
Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP.

How is chromatin structurally different from chromosomes?
Answer:
The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix
which sparrow would have the advantage if all fod sources were to disappear on the hypothetical island, leaving only marbles? if the marble remained the only food source, which kind of beak would the sparrow population have in the several years
Answer:
The spikes would be pointed and long, strong, to be able to break the surface of the marble and the particles.
Explanation:
The adaptation of the beaks is the selection of the fittest, in nature the species that best adapts and evolves according to the changes in the environment that surrounds it survives.
This was mentioned by Charles Darwin.
An advantage of using cell models when studying cells is that the cell models-
Answer:
The answer is H
Explanation:
The correct answer is that the cell model E. show cell shape and tiny organelles found in the cell that helps in the identification of the cell and their organelles.
Cell models are models that represent biological cells as discrete entities. These models help in representing the cell shape and components of the cells.
These are used in various biological fields such as computational biology, cellular biology and are also used in studying the cell and comparing them to identify the cell and its organelles.
By the shape and its tiny organelles, one can identify and find the cell, as prokaryotic cells lack various cell organelles, similarly, animal cells and plant cells have distinct shapes, and some cell organelles.
Thus, the correct answer is option E. show cell shape and tiny organelles found in the cell

Based on the thin layer of sediment on his flooded farm,
James Hutton concluded that strata:
A Are made of large rocks
B
Settle in vertical layers
C
Are formed by catastrophes like floods and earthquakes
D
Take many thousands of years to form
Answer:
D. Take many thousands of years to form
Explanation:
James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.
This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.

What are the main differences between asexual reproduction and sexual reproduction?
1. Asexual reproduction requires two parents and produces non-identical offspring, while sexual reproduction requires only one parent and produces identical offspring.
2. Asexual reproduction requires two parents and produces identical offspring, while sexual reproduction requires only one parent and produces non-identical offspring.
3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.
4. Asexual reproduction requires only one parent and produces non-identical offspring, while sexual reproduction requires two parents and produces identical offspring.
Answer:
3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.
Explanation:
Asexual - one parent only. Offsprings looks identical
You could see that in plants and flowers where each offspring looks the same
Sexual - two parents. Offsprings do not look identical
Ex : Animals and humans. We need a male and a female/ egg + sperm. The offsprings produced are non identical as genes from both parents are included
Answer:
3
Explanation:
asexual requires only one parent (think Jurrasic park lost worlds with the girl and the velociraptor they both are products of asexual reproduction)
sexual requires two parents to make the baby

Answer:
Great strides have been made in the early detection of cancer in humans through the process of electrophoresis and genetics, which analyzes protein signatures.
Explanation:
The protein misfolds, or the malformations that are seen in immunofluorescence or electrophoresis help us detect malignant neoplasms in early stages, although the best way is to check if the 4 genetic mutations necessary to be able to determine and it is a cancerized field or cells were met. cancer with malignant potential, this is determined by means of genetic analysis where the promoter, inhibitor, regulatory genes and the oncogene are checked.
