Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
Explanation:
A histogram is a graphical representation of a variable using bars. In such a bar, its area is proportional to the frequency of the values represented. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest. On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented. Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).
Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.
The population can be given as the number of people living in a specific area. The histogram represents the population, with frequency as the function of the area.
What is a histogram?A histogram is the graphical representation of the data in the form of bars. The population is given as the number of people in an area.
The population in the area is termed as frequency. The bar graph represents the frequency of population as the function of the area and thereby helps in the determination of the population.

Succulents and cacti often have short, thick leaves with a waxy coat. What function does this structure serve?
A) retains water
B) the plant uses less energy to grow these short leaves and conserves energy
C) prevents water from evaporating off leaves
D)all of the above
Answer:
C) prevents water from evaporating off leaves
Explanation:
Succulents and cacti are a group of plants known as XEROPHYTES. These are plants that grow and survive in areas or conditions where there is lack of water e.g deserts.
However, these plants need to adapt to the low or no water condition and one of the ways they do this is by possessing short, thick leaves with a waxy coat. This enables them to preserve water that would have been lost via transpiration from the leaves.
Answer:
(c) prevent water from evaporating off leaves

1. Sebaceous
2. Ceruminous
Answer:
A. Ceruminous
B. Sebaceous
C. Ceruminous
D. Ceruminous
E. Sebaceous
F. Sebaceous
Explanation:
Ceruminous glands are modified sweat glands located subcutaneously in the cartilaginous two-thirds of the external auditory canal. Ceruminous glands produce together with sebaceous glands the cerumen (i.e. earwax), which protects the ear canal against physical damage and/or microbial infections. On the other hand, sebaceous glands are glands in the skin that secrete sebum, an oily, waxy substance that lubricates the hair and skin of mammals. These glands (sebaceous) are affected by sex hormones like testosterone that enlarges the glands due to the increased cell proliferation rate and estradiol, which reduces the size of the glands due to the accelerated cell breakdown. Sebaceous glands are holocrine glands in which secretions are produced in the cytoplasm of the cells and then they are released by the rupture of the plasma membrane, while ceruminous glands are apocrine glands where the accumulated secretion is pinched off with a portion of the cell.

Compare and contrast the advantages and disadvantages of wind power and geothermal power
Answer:
An Overview of Geothermal Pros and Cons:
Pros Cons
This energy source is more environmentally friendly than conventional fuel sources. The largest single disadvantage of geothermal energy is that it is location specific.
A source of renewable energy. Gases are released into the atmosphere during digging.
The number of exploitable geothermal resources will increase with ongoing research and development in the industry. Geothermal energy runs the risk of triggering earthquakes.
A sustainable source of energy as its always available unlike wind and solar. Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.
A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy. Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.
No fuel is required.
Increase in exploration meaning that new technologies are being created to improve the energy process.
Pollution levels are much lower compared to fossil fuels.

How does human population growth and resource use impact biodiversity?
As human populations increase, the demand for resources such as food, water, and energy also increases.
What is biodiversity?Biodiversity refers to the variety of life on Earth, including the variety of species, ecosystems, and genetic diversity within species.
Human population growth and resource use have a significant impact on biodiversity. This leads to habitat destruction, pollution, and climate change, all of which have negative impacts on biodiversity.
Habitat destruction: As human populations grow, they need more land for agriculture, settlements, and infrastructure development. Pollution: Human activities such as industrialization and transportation produce pollutants that can harm biodiversity. Climate change: Human activities such as burning fossil fuels for energy production lead to the emission of greenhouse gases, which contribute to climate change.Thus, human population growth and resource use impact biodiversity by causing habitat destruction, pollution, and climate change.

How does structure of a cell suggest it's function?
Answer:
The structure of the cellular membrane suggests that it may be a barrier; its function as a selectively permeable membrane/barrier proves this to be true. The structure of the nucleus in a cell suggests that one of its chief purposes is to house and pass on DNA; its function helps to confirm this.

In Wakanda, in a population in Hardy-Weinberg equilibrium, the frequency of the single recessive allele controlling vibranium assimilation, which affects superhuman abilities, is 0.2. What is the percentage of the population that is heterozygous for this allele
Answer:
32%
Explanation:
Hardy–Weinberg equilibrium is also known as Hardy–Weinberg law. The idea of Hardy–Weinberg equilibrium is about the frequency of alleles in a population. The frequency of an allele in the population will always remain the same in a population if that population is not influenced by any evolutionary consequences.
Hardy–Weinberg equilibrium binomial expression formula is p2+2pq+q2=1. Suppose the frequency of recessive allele = q.
and another normal allele is = p
Here Q = 0.2 so P will be 1- Q or 0.8
By Hardy–Weinberg equation p2+2pq+q2=1, Here 2pq denotes the frequency of recessive allele, so 2pq = 2 × 0.2 × 0.8 = 0.32, if converted into percentage it will be 32%.

Which of the following is a disadvantage of planting a variety of crops rather than a monoculture?
A.) It is more likely to lead to crop failure.
B.) It can decrease farming efficiency and profit.
C.) It can promote biodiversity in ecosystems.
D.) It can lead to an increased risk of parasite infection.
Answer:
D.) It can lead to an increased risk of parasite infection.
Explanation:
Monoculture is a system of farming or cropping whereby a single crop is planted on a given area of land. The opposite of this system of farming is known as multiple cropping, where a variety of crops are cultivated.
One disadvantage of planting a variety of crops over a single crop in monoculture is that it increases the risk of parasite/pest attack on the crops. Parasites and pest can easily shift to the variety of crops planted in the farm.
