Write a paragraph about the rocks used to construct the Great Sphinx and pyramid of the Giza in Egypt.

Answer:

The correct answer is- Family

Explanation:

All the organisms are classified into seven different taxonomic groups and these groups are kingdom, phylum, class, order, family, genus, species. The highest largest taxonomic level is the kingdom and the lowest and smallest is species.

Leo is the species, Panthera is the genus and Felidae is a family of lion. The order of lion is Carnivora, class is Mammalia, phylum is Chordata and kingdom is Animalia. Therefore Felidae is the family of lion at taxonomic level.

Explanation:

When viewing cells through a microscope and noticing that each cell has a different structure, it can be inferred that these cells have different functions or come from different types of organisms or tissues. The variation in cell structure is typically linked to the specific roles each cell performs, as a cell's structure is tailored to its function in accordance to the principle known as 'form follows function' in biology.

Cells are the basic structural and functional units of life, and their structures are intimately linked with their functions. The concept of 'form follows function' suggests that the structure of a biological entity will be shaped by the particular functions it performs. If the cells observed are structurally distinct, it implies that they were designed to carry out different tasks or come from various environments. For example, a neuron in the nervous system has a very different structure compared to a red blood cell, reflecting their unique roles in the body. Similarly, plant cells differ from animal cells in key structural components like cell walls and chloroplasts, which are related to their functions in photosynthesis and maintaining rigidity. Noticing different structures under the microscope implies that there is a diversity of cell types and possibly a range of biological functions being observed.

The answer is B cerebellum

Explanation:

Effective sanitizers are created using 60% to 80% isopropanol or ethanol, with glycerin or ethylene to maintain skin softness.

To make sanitizer effective, it is common to use a combination of isopropanol or ethanol at a concentration of 60% to 80%, with the remainder typically being substances like ethylene or glycerin to keep the skin soft. These alcohols work by denaturing proteins and disrupting cell membranes, leading to cell lysis. For a tool to be effectively sanitized, it should be sprayed or dipped in the sanitizer and allowed to air dry without being wiped off with a sanitizing wipe.

Factors such as concentration, pH, temperature, and exposure time are crucial in determining the effectiveness of a sanitizer. Typically, alcohols are used in about a 70% aqueous solution as they require water to prevent the rapid coagulation of proteins, which could hinder the disinfectant's ability to penetrate cell membranes effectively. It is also important to select a disinfectant that is suitable for the contaminants present, cost-effective, non-toxic, and has a good shelf life.

Explanation:

Predators are considered a biotic limiting factor.

The predators are a part of the natural ecosystem. They control the population growth of the preys by hunting them. Thus they play a key role of bringing a balance within the various trophic levels of the ecosystem. They also drive evolution of preys by exerting a predation pressure on them. The preys that are not able to come up with strategies for survival fall in numbers.

The rusty crayfish is harmful to native species of crayfish because it clear cuts the bottom of waterways leaving native species without a food supply. This statement is True.

Crayfish are defined as freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. They are also known as crayfish, crayids, crabobs, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, bebugs, or yabbies.

More than half of the more than 500 species are found in North America where almost all live in freshwater, although some species are found in brackish or brackish water.

Crayfish are characterized by a fused head and thorax, or segmented body midsection, that is sandy yellow, green, red, or dark brown in color. Some fishes like Rusty crayfish are harmful due to clear cuts the bottom of waterways leaving native species without a food supply.

Thus, the rusty crayfish is harmful to native species of crayfish because it clear cuts the bottom of waterways leaving native species without a food supply. This statement is True.

Answer:

Solar energy, biogas, Electric energy.

Explanation:

Although solar energy and biogas are types of renewable energy that guarantee little impact on nature, the best alternative to generate electricity at home is still electricity. This is because solar energy can only generate electricity when the sun is available, that is, there would be no electricity at night and during winter. In addition, installing solar panels is very expensive. The price would also be a problem in the use of natural gas, since its use is usually very expensive. In that case, the best option would be electricity.

However, we cannot forget to point out that the combined use of the three energies would be great for a home, since it would bring savings and reduce the environmental impact.

Transcription is a process where a copy of mRNA is formed from one of the DNA strand. For this, DNA strand has to open up and complimentary bases are added to make the mRNA copy. But this copy doesn't include the portion which is not part of the genes. This waste portion is called as "intron".

The answer is; detecting stars that are behind nebulae that would normally block out other stars

Radio  waves have large frequencies unlike the other waves of the electromagnetic spectrum. Due to their large wavelength, they are much larger than the size of an atom hence cannot be blocked or deflected by atomic nuclei. This is unlike gamma rays (and other short wavelength electromagnetic radiation) that are smaller than atoms and easily blocked and deflected by atomic nuclei. Such radiations are extremely attenuated when they pass the through nebula cloud. Radio waves hence overcome this challenge.

Answer:

The correct answer is scientific knowledge can be revised with time.

Explanation:

The kingdom classification system is a system of classifying organism based on their similar and distinctive characters.

Linnaeus divided the nature into three kingdoms-animal, plants and mineral kingdom but this kingdom showed no relationship among them.

This classification system has kept on changing with the advancement in science and addition of new information to the science like Ernst Haeckel in 1866 proposed third kingdom of life called Protista which with the development in microscopy got changed again by Copeland as he proposed a fourth kingdom system called Monera. In 1969, Robert Whittaker proposed a fifth kingdom called Fungi which again with the advancement in molecular studies got changed by Carl Woese in 1970 as he divided the prokaryotes in Eubacteria and Archaeobacteria.  

This shows that scientific knowledge expands and  changes with time with the advancement in technology and ideas which lead to the changes in the existing information so has to be revised.

Thus, scientific knowledge can be revised with time is the correct answer.

The energy consumed by a 1.200 kW hair dryer operating for 15 minutes is 0.3 kWh, calculated using the power rating and operation time of the appliance.

To calculate the amount of energy used by a 1.200 kW hair dryer running for 15 minutes, we first need to understand that the power rating (kW) is a measure of energy consumed per unit time. Therefore, the total energy consumed will be the power rating multiplied by the time period. As a point of reference, a 1.000 kW (or 1000 W) appliance will consume 1 kWh of energy if it ran for an hour. However, our hairdryer is 1.200 kW and only runs for 15 minutes.

First, we need to convert 15 minutes to hours, which is 15/60 = 0.25 hours. Then, multiply the power of the hairdryer by the time used in hours, which is 1.200 kW * 0.25 hours = 0.3 kWh. Therefore, the energy consumption for drying hair with this hairdryer is 0.3 kWh.

Answer: see explanation

Explanation:     Fat bodies in frogs store energy and are attached to the ovaries in females and the testes in males. They provide a source of energy during periods of low food availability and support reproduction.

Final answer:

Fat bodies in frogs act as energy reserves for breeding activities and during metamorphosis. Frog eggs are protected by a gel-like substance meanwhile ovaries produce eggs and secrete hormones necessary for reproduction.

Explanation:

The fat bodies attached to the reproductive organs in frogs serve as energy reserves. These reserves are especially important during the breeding season when frogs require extra energy for reproductive activities such as egg-laying and mating. The fat bodies are rich in lipids and can be metabolized to meet the energy demands when food is scarce or not available during the breeding season. Also, during metamorphosis, when a tadpole transitions to an adult frog, these fat bodies provide the necessary energy for this energy-consuming process.

Frog eggs are surrounded by a gelatinous substance, often referred to as "jelly." This jelly provides protection to the eggs by insulating them against physical damage and predation, as well as maintaining a moist environment, which is crucial for the survival of the embryos. Frogs typically lay eggs in communal areas to increase the odds of fertilization, and apart from a few species that exhibit parental care, most amphibians do not tend to the eggs after laying them.

Ovaries in female frogs, as in other animals, are reproductive organs that produce eggs (ova) and secrete hormones such as estrogen. The ovaries are held in place by ligaments and consist of a medulla and cortex, with the cortex containing the eggs surrounded by follicular cells.

Protists are single-celled organisms with a wide range of structures and functions. Therefore, option (3) is correct.

The term "protist" refers to a diverse group of eukaryotic microorganisms that are not classified as either plants, animals, or fungi. Structures ranging from unicellular to colonial to multicellular can be found in them. The vast majority of protists consist of a single cell. Examples of these organisms include amoebas, paramecia, diatoms, and dinoflagellates.

Some protists perform photosynthesis or have specialised features. Protists can be photosynthetic, heterotrophic, or mixotrophic. Protists lack specialised tissues and organs like multicellular creatures. Therefore, option (3) protists are single-celled organisms with a wide range of structures and functions is correct.

The ground tissue in plants is similar to animal organs.

The ground tissue of plants incorporates all tissues that are neither dermal nor vascular. It very well may be isolated into three kinds dependent on the idea of the cell dividers. Parenchyma cells have thin essential dividers and generally stay alive after they end up developing.

Solstice and equinox refer to positions where the Earth's tilt relative to the Sun causes the longest and shortest days, or equal lengths of day and night, respectively, due to the 23.5° tilt of Earth's axis.

The terms solstice and equinox refer to specific positions in Earth's orbit around the Sun. A solstice is a point in the year when the Sun reaches its greatest distance north or south of the equator, leading to the longest or shortest day of the year. The summer solstice occurs around June 21, causing the longest day in the Northern Hemisphere, while the winter solstice occurs around December 22, resulting in the shortest day. Conversely, an equinox occurs when the tilt of Earth's axis is such that the Sun is directly above the equator, leading to equal lengths of day and night across the planet; these occur around March 21 (the vernal equinox) and September 22 (the autumnal equinox). These events are intimately related to the 23.5° tilt of Earth's axis of rotation. The cycle of the seasons is a direct result of this tilt, with the angle between Earth's axis and the Earth-Sun line varying throughout the year.

To find the range of the temperature measurements, subtract the lowest measurement (11°C) from the highest (31°C), resulting in a range of 20°C.

The question asks to find the range for the set of temperature measurements provided. The range of a set of numbers is determined by subtracting the smallest number from the largest number in the set.

First, identify the highest and lowest temperature measurements in the set. In this case, the highest temperature is 31°C, and the lowest temperature is 11°C.

Then, calculate the range by subtracting the lowest temperature from the highest temperature:

Range = Highest temperature - Lowest temperature
= 31°C - 11°C
= 20°C.

Therefore, the temperature range for the provided measurements is 20°C.
