The structure that extends posteriorly from each kidney is called a ureter, the temporary reservoir for urine is called the urinary bladder, and the tubular structure that allows urine to flow to the external urethral orifice is called the urethra.
What is the role of kidneys?The kidneys are a pair of bean-shaped organs responsible for producing urine by filtering waste products and excess fluid from the blood. Urine then flows down the ureters that extend from the kidneys to the urinary bladder.
The urinary bladder is a muscular sac responsible for storing urine until it is excreted from the body. When the urinary bladder is full, the urinary bladder gets a contract which allows urine to flow through the urethra.
The urethra is a tubular structure and is longer in males and the urethra is shorter and opens directly into the vulva in females. The urethra is lined with urothelium to accommodate the flow of urine.
Therefore, a structure that extends from each kidney is called a ureter, temporary reservoir for urine is called the urinary bladder, and the tubular structure that allows urine to flow to the external urethral orifice is called the urethra.

In 1-2 sentences, relate the impact of the industrial use of water for (fracking) with the availability and quality of water. hydraulic.fracturing
The industrial use of water for hydraulic fracturing (fracking) can impact the availability and quality of water due to the large volumes of water required and the potential contamination of water sources by chemicals used in the fracking process.
The industrial process of hydraulic fracturing, commonly known as fracking, involves injecting large volumes of water, sand, and chemicals into underground formations to extract natural gas or oil.
This process requires significant amounts of water, which can strain local water supplies, especially in areas already facing water scarcity or drought. The extraction and treatment of this water can also lead to increased water pollution and contamination, as the chemicals used in the fracking fluid can potentially leak into groundwater sources or be released into surface water bodies.
The disposal of wastewater generated from fracking operations can also pose challenges, as it requires proper treatment and management to prevent contamination of water resources.
Overall, the industrial use of water for fracking can have significant implications for both the availability and quality of water in affected regions.

per kcal of food produced, which of the following sources of animal protein requires the most land and water, and generates the largest quantity of greenhouse gases?
The food production industry, especially animal farming, has severe effects on the environment. Animal farming, in particular, requires large amounts of resources, including land, water, and fossil fuels, while also releasing large amounts of greenhouse gases into the environment.
As per the studies and data available, beef production is the most resource-intensive form of animal farming. The production of beef requires more land and water than any other type of animal farming. According to the UN's Food and Agriculture Organization (FAO), 30% of the Earth's land surface is used for beef cattle production. Beef production also requires about 20 times more land and 10 times more water than the production of other animal products, such as dairy, eggs, and chicken.
Thus, beef production is the most resource-intensive form of animal farming, requiring the most land and water and releasing the largest quantity of greenhouse gases. Consequently, researchers have concluded that reducing the consumption of beef could have a significant positive impact on the environment.

the type of receptor that readily adapts to a stimulus is known as a ________ receptor.
The type of receptor that readily adapts to a stimulus is known as a phasic receptor.
"Phasic" refers to a type of response or activity characterized by its transient and rapid nature. In various biological systems, including the nervous system, the term "phasic" is used to describe a dynamic and short-lived response to a stimulus. In the context of sensory perception, phasic receptors are responsible for detecting changes or variations in stimuli over time.
These receptors exhibit a rapid response when initially stimulated, but their activity diminishes quickly if the stimulus is sustained. For example, in the visual system, phasic cells respond strongly to the onset or offset of a visual stimulus but show reduced activity during a constant stimulus. Phasic responses are essential for detecting and attending to salient changes in the environment, while sustained or tonic responses are involved in encoding ongoing or constant stimuli.

A red bloom cell has diameter of 0.008mm. a model of the red blood cell has a diameter of 80mm. What is the scale of the model
Scale of the model: 1:10,000. To find the scale of the model, we need to compare the size of the model to the actual size of the red blood cell. Given that the diameter of the red blood cell is 0.008mm and the diameter of the model is 80mm, we can calculate the scale by dividing the diameter of the model by the diameter of the actual cell.
Scale = Model diameter / Actual cell diameter
Substituting the given values:
Scale = 80mm / 0.008mm
Simplifying the expression:
Scale = 10,000
Therefore, the scale of the model is 1:10,000.
1. Identify the diameter of the red blood cell: 0.008mm.
2. Identify the diameter of the model: 80mm.
3. Use the formula Scale = Model diameter / Actual cell diameter.
4. Substitute the values into the formula: Scale = 80mm / 0.008mm.
5. Simplify the expression to find the scale: Scale = 10,000.
6. The scale of the model is 1:10,000, indicating that the model is 10,000 times larger than the actual red blood cell.

How does changing the environment that the bacteria are in affect their population
Bacteria respond to environmental changes by expressing or suppressing genes. This affects the organism's inner and surface chemistry.
What are the effects of environment on bacteria?Bacteria are common, largely free-living organisms that frequently only have one biological cell. They make up a vast domain of prokaryotic microbes.
When their environment suddenly changes, bacteria respond by expressing or inhibiting the expression of a vast number of genes. This reaction alters the chemistry of the organism's surface as well as its internal features.
Although bacteria can survive at higher and lower temperatures than humans, they thrive in an environment that is warm, wet, protein-rich, and pH neutral or slightly acidic. However, there are several exceptions. While certain bacteria can survive in environments of extreme heat or cold, acidity or salinity, others can.

Which most correctly describes the process of pollination in flowering plants?
The parent plant is dispersing its male offspring to mate with the female offspring of another plant.
The plant is providing pollen as food for insect visitors.
Pollen is the sperm of the parent plant and it is carried by the wind or an insect to the egg of another plant.
Pollen from the anther of one flower is carried by insects to the anther of another flower.
The statement that best describes the process of pollination in flowering plants is: ''pollen from the anther of one flower is carried by insects to the anther of another flower.''
What is pollination?Pollination is a process in which pollen is transferred from the male reproductive organ (anther) of a flower to the female reproductive organ (stigma) of a flower of the same species, resulting in fertilization. Pollination is essential for plant reproduction and is facilitated by a variety of agents, including wind, water, birds, bees, and other animals.
In flowering plants, pollination usually occurs as follows: Pollen is produced in the anthers of the stamen, which are the male reproductive organs of a flower. Pollen grains are transferred from the anthers to the stigma, which is the female reproductive organ of a flower, either by wind, insects, or other animals.
Once the pollen grain reaches the stigma, it germinates, and a pollen tube is formed, which grows down through the style to the ovary of the flower.The pollen tube delivers sperm cells to the ovary, where they fertilize the egg cells, resulting in the formation of seeds. Finally, the ovary develops into a fruit, which contains the seeds, and the cycle begins anew.
