The correct answer is The cell is prokaryotic because it does not have any membrane-bound organelles.
Explanation:
Prokaryotic cells are different from eukaryotic cells because prokaryotic cells do not have organelles surrounded by a membrane, while eukaryotic cells do. These organelles include a nucleus, ribosome, among others. On the opposite, the DNA material is located inside the cell forming an undefined structure and the cell is protected by the cell wall and the cell membrane. In this context, the cell of the image is prokaryotic because there are no defined organelles inside it.

2. During which phase would the cell undergo anaphase? *
A. Phase A
B. Phase B
C Phase C
D. Phase D
Answers
Anaphase occurs during the M phase (mitosis) of the cell cycle and is not represented by any of the provided options (A, B, C, or D).
Anaphase is a critical stage in cell division, specifically in mitosis or meiosis. It occurs after metaphase and before telophase. During anaphase, the sister chromatids, which are replicated chromosomes held together by a centromere, separate and move towards opposite ends of the cell.In the context of the cell cycle, anaphase takes place during mitosis. The cell cycle consists of four phases: G1 (gap 1), S (synthesis), G2 (gap 2), and M (mitosis). Mitosis is the M phase, which further consists of four stages: prophase, metaphase, anaphase, and telophase.Therefore, the correct answer is not provided in the given options. Anaphase occurs during the M phase or mitosis and is not associated with any specific phase (A, B, C, or D) mentioned in the question.

Testosterone is the hormone Indicated by the small hexagon in the red circle.
What is testosterone?Testosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Testosterone is the male sex hormone that is made in the testicles. Testosterone hormone levels are important to normal male sexual development and functions. During puberty (in the teen years), testosterone helps boys develop male features like body and facial hair, deeper voice, and muscle strength.
Testosterone is a sex hormone that plays important roles in the body. In men, bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating testosterone is converted to estradiol, a form of estrogen.

C.Industrial uses,such as manufacturing
D.Agricultural uses such as watering crops
Answers
The main use of freshwater worldwide is the agricultural uses such as watering crops. Thus, the correct option is D.
What is freshwater?Freshwater is the water which contains only minimal quantities of dissolved salts and minerals, thus distinguishing it from that of sea water or brackish water. All the freshwater ultimately comes from precipitation of atmospheric water vapor, reaching the inland lakes, rivers, and groundwater bodies directly, or after the melting of snow or ice.
Healthy freshwater environments are the main water supply for drinking, growing crops, manufacturing, energy, and transport purpose. They also help to prevent erosion, dispose of waste material and provide natural protection against flooding.

Answers
The trend that is evident is: Initially, there seems to be support for Mel's hypothesis, but the gold data is not consistent with the predicted trend.
Option C is correct.
How do we calculate?The data for zinc, nickel, copper, and silver shows that as the density increases, the melting point tends to increase.
From the data we can see , the data for gold does not follow this trend, as its density is lower than silver but its melting point is higher.
Therefore, while there is some initial support for Mel's hypothesis, the inconsistency with gold indicates that the relationship between density and melting point is not solely determined by density.

water boiling
sugars digested by saliva

Answers
Explanation:
An enzyme called salivary amylase helps in the breakdown of sugar into small particles. This enzyme affects the sugar for a small period of time in the mouth.
Once, salivary amylase reaches the stomach it becomes inactive because of the acid present in stomach. Further, this acid breaks the sugar molecules and these molecules are sent to the intestine for further reaction.
Thus, we can conclude that sugars digested by saliva is a chemical change.

Answers
The evolution of cuticles presented land plants with the challenge of preventing water loss from leaves and preventing the entry of CO2 required for photosynthesis, while stomata allow CO2 to diffuse and can close to prevent water loss.
1. Cuticle prevents water loss from leaves and prevents entry of CO2 required for photosynthesis.
2. Stomata allow CO2 to diffuse and can close to prevent water loss.
The waxy cuticle on the surface of leaves helps prevent water loss, but it also creates a barrier that prevents gases from entering and leaving the plant. This presents a problem for photosynthesis, which requires the uptake of carbon dioxide (CO2) and the release of oxygen (O2).
Stomata, have tiny pores on the leaf surface, allowing CO2 to diffuse into the leaf and O2 to diffuse out. Additionally, they can close to prevent excessive water loss through transpiration. The evolution of stomata allowed plants to thrive on land by overcoming the challenge of gas exchange while minimizing water loss.

D: Reaction of saliva, stomach acid, bile, and pancreatic juices with food
Answers
The example that includes only chemical changes that occur in the digestive process is the reaction of saliva, stomach acid, bile, and pancreatic juices with food. Option D.
What are chemical changes?Chemical changes refer to changes to the chemical properties of substances. In biological reactions, these substances are referred to as reactants.
Chemical changes are different from physical changes. In physical changes, only the physical properties of substances are altered while their chemical properties remain intact.
When a substance changes chemically, its physical properties most often change along. However, this is not in all cases.
Thus, looking at the examples given, their classification into either physical or chemical changes is as follows:
Absorption of nutrients by villi in the small intestines: physical changeChewing and swallowing food: physical changeRecycling of water from dissolved food back into the body: physical changeThe reaction of saliva, stomach acid, bile, and pancreatic juices with food.When saliva, stomach acid, bile, and pancreatic juices react with food, the chemical properties of food change because the enzymes convert different components of food from one form to another as part of the process of digestion.

Describe the tendency of population movement in South Africa over
the same 50-year period.
3.1.3 What influence does this population shift have on agriculture?
Answers
Overall, the population shift in South Africa has had a negative impact on agriculture, leading to a decline in the sector and decreased food security for rural communities.
What is population?Population refers to the total number of individuals of a particular species or group living in a specific area or region. In the context of human populations, it refers to the number of people living in a particular geographic area or country. Population can also refer to subgroups within a larger population, such as age groups, ethnic or racial groups, or socioeconomic groups. Population can be measured and analyzed in various ways, including through demographic data such as birth and death rates, migration patterns, and population density.
Here,
Over the past 50 years, there has been a significant population shift in South Africa, with many people moving from rural areas to urban areas in search of better economic opportunities, education, and healthcare. This trend is known as urbanization and is a common phenomenon in many developing countries.
As people move from rural areas to urban areas, the population density in urban areas increases, while rural areas become less populated. This population shift has had a significant impact on agriculture in South Africa. As more people move to cities, there is less demand for agricultural products, leading to a decline in the agricultural sector. This has resulted in the loss of agricultural land, reduced productivity, and decreased food security for rural communities.
In addition, the population shift has also led to changes in land use. As urban areas expand, they often encroach on agricultural land, leading to land fragmentation and reduced agricultural productivity. This can also lead to conflicts between urban and rural communities over land use and resource allocation.
