Cape Town, South Africa has a significant water shortage. The amount of water available is not sufficient to support the current human population of the city.
Which three factors most likely contributed to the growing water shortage?
- Strict water management policies.
- Naturally-occurring drought conditions.
- Underdeveloped alternative and supplemental water sources.
- Migrations of residents out of the city and into surrounding areas.
- Higher demand for water than natural reservoirs accumulate each year.
Explanation:
The city's water supply shortage seems to be the result of a combination of physical, social, and political factors. Well below-average rainfall patterns, the increasing unpredictability of weather conditions due to anthropogenic climate change impacts, population growth, and government mismanagement have produced one of the worst urban water crises in recent memory.
here is the reason your explanation from the water shortage now just figure out what the factors are in your answers I would say it's naturally occurring drought conditions because it says on here well below average rainfall patterns and climate change
Water shortage can occur as a result of mismanagement practices by humans or as a result of natural occurrences such as droughts.
What is water shortage?Water shortage refers to a situation in which there is not enough water to meet the daily water needs of the human, animal and plant population in a particular area.
The water shortage issue in Cape Town, South Africa could have been as a result of:

A.Ubiquitous use of catalysts by living systems
B.Near universality of the genetic code
C.Structure of the nucleus
D.The flow of genetic information from DNA to RNA to protein
E. The directionality of protein synthesis
Answer:d
Explanation:
The organism is made of genetic material that it inherits from the parent cell. The universality of the genetic code provides evidence of the common ancestry of all life. Thus, option B is correct.
What is a genetic code?A genetic code is a triplet of nucleotides that are also defined as codons that characterizes a specific amino acid produced through the process of translation. It consists of the DNA or RNA as the base that forms the codons.
The codons have been unambiguous for a type of amino acid it codes, universal for all living organisms irrespective of the kingdom, and redundant. They are crucial evidence that supports the common originality theory of organisms.
Therefore, option B. the universality of the genetic code is evidence that supports the theory of common ancestry.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer, 75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant over brown (w). During the summer, the field where they live experiences a drought. The summer drought lasts for two years, through many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the drought?
Answer:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
Explanation:
hope this helps!
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
Thus, the rabbit population will consist of 35% white rabbits and 65% brown rabbits.

Our ability to be conscious of some aspects of our environment while
ignoring others is called:
A. the conscious mind.
B. the two-track mind.
C. selective attention.
O D. preconscious attention.
SUBMIT
Selective attention is our ability to be conscious of some aspects of our environment while ignoring others. Therefore, the correct statement is option C.
What is selective attention?
Selective attention is the ability of our mind to be conscious of some aspects while ignoring others. In selective attention, our mind focuses on a certain aspect of the environment and filters out the rest of the aspects. Selective attention is useful as it allows one to focus only on the useful information and responds to an important stimulus in an environment.
Selective attention can be affected by various factors such as our dedication to particular interests and goals. For example, while we are driving in heavy traffic, we will only focus on the potential hazards and ignores all the other information, such as education, career, etc.
Selective attention involves top-down and bottom-up processing. Top-down processing involves the use of information, such as knowledge, goals, etc. to retain our attention, while bottom-up processing involves the use of sensory information to capture our attention.
Therefore, selective attention is our ability to focus on only certain aspects of the environment.

Which of the following is NOT a function attributed to Glia?
~They prevent toxic substances from reaching the brain.
~They process information going into the neuron
~They eliminate foreign substances inside neurons.
~They provide insulation for axons.
Answer:
~They process information going into the neuron
Explanation:
This is because Glia or neuroglia cells are cells found in the central nervous system that is brain and spinal cord and they did not transmit electrical impulses. Glia cells don't carry information because they don't carry electrical impulses. The cells include epipdymal cells,Schwann cells e.t.c.
They perform four major function and they include; They provide support and supply nutrients and oxygen to the cells,it prevent toxic or foreign substances from entering the neurons,they provide insulation for axons.

Explanation:
Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).
(numbers have been slightly modified for the purposes of this worksheet).
Field Data Summary
Collecting Site Substrate Color Number of Mice Phenotype
Light Dark
1 Dark 22 3 19
2 Light 80 74 6
3 Light 22 19 3
4 Dark 28 3 25
5 Light 58 25 33
6 Dark 65 9 56
1. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on light-colored substrates.
2. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on dark-colored substrates.
3.Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the light, rocky, granite substrate.
4. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the dark, rocky lava substrate.
5. Which fur color seems to have the greatest overall selective advantage?
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13frequencies of dark-colored mice ≅ 0.873)
q² = 0.74p² = 0.02 2pq = 0.244)
q² = 0.13p² = 0.42pq = 0.465)
The dark-colored fur seems to have the greatest overall selective advantage
6)
Dark lava, that changed the color of the substrate, from light to dark.
7)
Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.
8)
To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.
