Explanation:
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:

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.

Low-carbohydrate diets became popular in the late 1990s and were quickly proclaimed to be a fast and easy method of weight loss. The effectiveness and safety of these diets are dependent on the activity and overall health of the individual as well as the total nutritional content of the diet. However, it is true that in some cases, these diets have been effective. What metabolic effects caused by eating a low-carbohydrate diet can be linked directly to a decrease in fatty acid synthesis and an increase in fatty acid oxidation?
a. release of insulin from pancreatic's cells
b. dephosphorylation of AMPK
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK
Answer:
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK
Explanation:
Low-carbohydrate diets (LCDs) stimulate the secretion of glucagon by a decrease in the blood glucose concentration. Glucagon is a key hormone secreted by pancreatic cells in the same way as insulin but in an opposite way. This hormone (glucagon) prevents glucose accumulation as hepatic glycogen, while insulin helps to the accumulation of glucose in the liver as glycogen, thereby acting to reduce hepatic glucose output. Moreover, the AMP-activated protein kinase (AMPK) is a kinase protein that mediates the phosphorylation and inhibition of acetyl-CoA carboxylase (ACC) in order to reduce the synthesis of malonyl-CoA, a key molecule that regulates myocardial fatty acid oxidation.
What if cellular respiration did not occur
Answer:
cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.
Explanation:
THE ANSWER IS FERMENTATION!!!!
Answer:
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

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).

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.

List and explain the characteristics of living things
Answer:
Life process
Movement
Respiration
Sensitivity
Growth
Reproduction
reason:
Life process
Explanation
Earthworms
Movement
All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun.
Earthworms use circular and longitudinal muscles to move through soil or along surfaces.
Respiration
Respiration is a chemical reaction that happens within cells to release energy from food.
The food that earthworms eat supplies their body with energy-rich molecules such as glucose. On entering the cells of their body, these molecules are broken down in a series of steps to release energy to be used by the body, producing carbon dioxide and water as waste products.
Sensitivity
The ability to detect changes in the surrounding environment.
Earthworms have light-sensitive cells scattered in their outer skin. Their skin cells are also sensitive to touch and chemicals.
Growth
All living things grow.
Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.
Reproduction
The ability to reproduce and pass genetic information onto their offspring.
Earthworms have both sperm and eggs within their bodies (they are hermaphrodites) but they cannot self-fertilise and need to mate with another individual. After mating, a cocoon containing the fertilised eggs is deposited in the soil.
Excretion
Getting rid of waste.
Earthworms excrete waste from their anus – the last segment of their body.
Nutrition
The intake and use of nutrients. This occurs in very different ways in different kinds of living things.
Earthworm nutrition comes from a variety of sources, depending on their species. Food types include manure, compost, plant material, fungi, microorganisms and decaying animals. They take in food through their mouths.

~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.
