The month that is carrying capacity that is most likely to be limited by water is: c. September.

This is due to the graph's apparent abrupt dip in water level around September, which indicates a decrease in the amount of available water resources.

As a result, the low water supply during this month may limit the carrying capacity, which refers to the maximum number of people that an area can support sustainably.

Answer:

A

Explanation:

The discovery of a series of fossils of human-like skulls from throughout the past 4 million years indicates the process of Punctuated equilibrium. Thus, the correct option is A.

Punctuated equilibrium may be defined as a type of speciation in which most of the time species are stable. But every now and then there is a disruptive event that promotes rapid change.

Gradualism may deal with the idea that evolution occurs at a slow but steady pace. Disruptive selection refers to environmental conditions that change in two different directions. Both of these processes do not make any sense here.

Answer:

option B

Explanation:

Gametes are haploid because a sperm and an egg fuse during fertilization to create a new organism with diploid cells. Mutations in somatic cells can affect an individual organism, but they do not affect the offspring since they are not passed on during reproduction.

During cellular respiration, sugars such as glucose are metabolized inside the cells. During this metabolization process, glucose bonds are broken releasing energy that is stored in ATP molecules that the cell can use.

In addition to the breaking of bonds, electrons are released which are then sent to the electron transport chain where they help to generate energy. This is important because these electrons are ultimately used to reduce the oxygen that we breathe, this oxygen is in the form of O2, so that when reduced it becomes H2O. Properly, this is a reduction of molecular oxygen but it could also be considered a bond-breaking since we separate the 2 oxygen atoms. Therefore, the answer is "oxygen".

A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic

A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.

Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.

They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.

The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.

Therefore, prokaryotes lack a distinct nucleus.

Answer:

Explanation:

When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:

1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.

2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.

3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.

4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.

5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.

6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.

Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

The standard deviation of the distribution is given as 17.15

Assuming that the distribution of IQ scores approximates a normal curve with a mean of 100, we can use the information given to find the standard deviation (σ) of the distribution.

First, we know that the IQ scores above 115 are considered superior, which means that the area under the normal curve to the right of 115 is approximately 0.15 (since approximately 15% of the population have IQ scores above 115).

Next, we know that approximately 1% of the population have IQ scores above 140. Since the distribution is assumed to be normal, we can use the properties of the normal distribution to find the z-score corresponding to the 99th percentile (since 99% of the population have IQ scores below 140).

Using a standard normal table or calculator, we find that the z-score corresponding to the 99th percentile is approximately 2.33.

We can then use the formula for z-score:

z = (x - μ) / σ

where z is the z-score, x is the IQ score, μ is the mean IQ score, and σ is the standard deviation of the IQ scores.

Plugging in the values we know, we get:

2.33 = (140 - 100) / σ

Solving for σ, we get:

σ = (140 - 100) / 2.33

σ ≈ 17.15

Therefore, the standard deviation of the IQ scores is approximately 17.15.

When talking about specific heat, it is correct to say that a gas's specific heat may be determined at constant pressure. The correct option is B.

The amount of heat needed to increase a substance's temperature by 1 degree Celsius or Kelvin is known as its specific heat. The specific heat of a gas can be measured at constant pressure.

The specific heat for gases can be calculated at either constant volume or constant pressure. The heat capacity at constant pressure (Cp) and heat capacity at constant volume (Cv) are the terms used to describe the specific heat when measured at constant pressure and constant volume, respectively. For the majority of gases, Cp has a larger value than Cv.

Thus, the ideal selection is option B.

Behavior, biological features, color, form, and size are a few examples of visible traits.

Explanation:

All of an organism's observable traits, or phenotype, are the outcome of the interplay between its genotype (total genetic inheritance) and environment.

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.

When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.
