On Isle Royale, wolves are the main predators of moose. The graph shows the changing wolf and moose populations on the island over a 50-year time span.
The graph plots the populations of moose and wolves in separate lines from 1955 to 2005. The two populations appear to follow opposite trends: when one population is higher, the other population is lower.
Which statement provides the strongest explanation for the trends in the two populations?
A. The populations of predators and prey are limited by abiotic factors only.
B. Predation acts a density-dependent limiting factor on prey, but not on predators.
C. Predation acts as a density-independent limiting factor on predators, but not on prey.
D. Predator-prey relationships act as density-dependent limiting factors on both predators and prey.
Answer:
D
Explanation:
The statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.
What is predator?Predator is defined as an organism that mostly hunts and consumes other organisms for food. The term "predator" refers to a species that hunts and eats specific other organisms. The animals that predators consume are referred to as prey.
Predator-prey interactions and prey-predator interactions are both crucial density-dependent population controls. The other population's size determines how each population changes in size. When the population density reaches a particular point, a density-dependent limiting factor takes effect. Competition, parasitism, and disease are other instances of density-dependent limiting variables.
Thus, the statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

A sample of a meteorite has a density of 23 g/ml. It takes up a volume of 147 ml.
What is the mass of this unknown sample?
Answer:
3,381 grams
Explanation:
The problem can be solved by using the formula for "Density." The formula for density is: Density (ρ) = [tex]\frac{mass}{Volume}[/tex]
Now that we know the formula, we can get the formula for the "mass."
mass = ρ x VolumeThe given density above is 23 g/mL while the given volume is 147 mL. We have the values of the density and volume, thus, it is easy to solve the problem.
Let's solve.
mass = 23 g/mL x 147 mLmass = 3,381 gramsThe mass of the meteorite is 3,381 grams.

What did scientists believe was contributing to the depletion of the ozone layer and why?
CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

why do the other planets take longer to orbit the Sun than the inner planets do
Answer:
Outer planets take longer to orbit than inner planets because of the greater distance they need to cover. They also are further from the sun weakening the power of the suns gravitational pull which causes then to orbit slower.

How much ATP is produced in 5 molecules of glucose in the presence of oxygen in an obligate aerobe?
Answer:
190 ATP molecules
Explanation:
Cellular respiration is the process whereby energy (ATP) is obtained in the cells of living organisms by breaking down glucose molecules. Cellular respiration can either be aerobic or anaerobic depending on whether oxygen is present or not.
In the presence of oxygen, aerobic respiration, which consists of three stages namely: glycolysis, Krebs cycle and oxidative phosphorylation, is employed. Per glucose molecule;
- Glycolysis produces 2 ATP molecules,
- Krebs cycle produces 2 ATP molecules
- Oxidative phosphorylation produces 34 ATP molecules
Hence, in total, 38 ATP molecules is produced per glucose molecule in aerobic respiration. According to the question, 5 molecules of glucose will yield 5 × 38 = 190 molecules of ATP.
Explain how the biogeochemical cycle are essential for life.
Because Earth has limited materials and room for deceased creatures, biogeochemical cycles are vital to life and ecosystems. Biogeochemical cycles transport and store these chemicals for living creatures.
What are biogeochemical cycle?Because there is a finite quantity of stuff on earth and a certain amount of room for dead species as well, biogeochemical cycles are crucial for life and significant to ecosystems. Additionally, biogeochemical cycles are crucial because they move and store these chemicals so that living things may use them.
The flow of nutrients and other elements between biotic and abiotic forces is referred to as "biogeochemical cycles" in most cases. The words "bio" and "geo," which refer to the biosphere, "geo" and "chemical," which refer to the elements that flow through a cycle, are the roots of the phrase "biogeochemical."

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why? mitochondria, because they rely on the ER as an energy source ribosomes, because they receive proteins made by the ER Golgi apparatus, because it packages proteins received from the ER cytoplasm, because it relies on the ER for structural support
Answer:
Golgi apparatus, because it packages proteins received from the ER
Explanation:
The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.
The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.
If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.

Answer:
d. Pluripotency markers
Explanation:
Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.
A student is investigating how substrate concentration affects the rate of anenzyme-catalyzed reaction. Which threevariables should be kept constant in the setup of thestudent’s investigation? Select all three variablesA. temperature of the reactionB. amount of enzymeC. amount of substrateD. amount of productE. pH of the reaction
Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
Temperature should be kept constant because enzymes operate at different activity rates depending on the temperature. The same goes for the pH as well with different enzymes having different optimal pH levels.
The amount of enzyme should be kept constant as well because different concentrations of enzymes can determine how fast the reaction will occur.
Essentially anything that could affect enzyme activity apart from substrate concentration should be kept constant.
