Answer:

The correct answer is D.) the curved surface of Earth.

Explanation:

The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.

Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

10. Chloroplast is the molecule that is involved in the process of photosynthesis other than water, C02 and light.

Light reaction is light dependent process in which light absorption, hydrolysis of water molecule, release of oxygen and formation of ATP  & NAPDH occurs in the Chloroplast.

In dark reaction, which not dependent on the presence of light directly is also called as carbon fixing stage. In this stage the products of light reactions are used to form the carbohydrates.

The molecule required for both the reaction is chlorophyll.

12. Glucose is the primary source of energy for most of the cells and hence is required by all the cells.

We get the energy by breaking down the glucose molecule into pyruvate in the process of glycolysis which is further processed to release ATP that is used as the energy currency in our cells.

Facilitated diffusion is a process of passive transport that requires carrier proteins or channels to facilitate the movement of specific molecules across a cell membrane.

Facilitated diffusion is a type of passive transport that allows specific molecules to move across a cell membrane from an area of higher concentration to an area of lower concentration. Unlike simple diffusion, which relies on the concentration gradient and the physical properties of molecules, facilitated diffusion requires the assistance of carrier proteins or channels.

Enzymes are one type of carrier protein involved in facilitated diffusion. They can bind to specific molecules and undergo a conformational change to transport them across the membrane. Enzymes are often involved in the transport of small molecules, such as ions or sugars.

Carrier proteins are another important component of facilitated diffusion. These proteins have specific binding sites for particular molecules. When the molecule binds to the carrier protein, it undergoes a change in shape, allowing it to pass through the membrane and be released on the other side. Carrier proteins are involved in transporting larger molecules, such as amino acids or larger sugars.

In addition to carrier proteins, facilitated diffusion can also utilize lipid or carbohydrate carriers. Lipid carriers, such as lipoproteins, can transport lipid-soluble molecules across the membrane. Carbohydrate carriers, on the other hand, are specialized proteins that transport carbohydrates, such as glucose, across the membrane.

1. c. Haplotype Recombinant.

2. c. trisomy 21 > Robertsonian translocation > PKU syndrome.

1. The term that does not involve multiple loci is c. Haplotype Recombinant. Haplotype refers to a set of genetic variations on a single chromosome, while recombinant refers to the reshuffling of genetic material during meiosis. It does not inherently involve multiple loci, but rather the arrangement of alleles at a single locus.

2. The correct order of DNA alterations, in large to small scales, that cause the phenotypes mentioned is c. trisomy 21 > Robertsonian translocation > PKU syndrome. Trisomy 21 refers to the presence of an extra copy of chromosome 21, resulting in Down syndrome, which is a large-scale alteration involving a whole chromosome. Robertsonian translocation involves the fusion of two acrocentric chromosomes, often resulting in rearrangements and genetic disorders. Phenylketonuria (PKU) syndrome, on the other hand, is caused by alterations in a single gene, resulting in the inability to metabolize phenylalanine. Therefore, the order from large-scale to small-scale DNA alterations is trisomy 21, Robertsonian translocation, and PKU syndrome.

Mitochondria and lysosomes carry out specific functions for the cell and are collectively called Organelles.

Inside cells, organelles are specialized structures that carry out a variety of tasks. Literally, the phrase refers to "tiny organs." Organelles provide specialized duties to keep a cell alive, just like organs like the heart, liver, stomach, and kidneys serve specific roles to keep an individual alive.

The mitochondrion, a large organelle also present in eukaryotic cells, is in charge of producing ATP, a substance used by living things as a source of energy. Many cells have hundreds of mitochondria.

These mitochondria feature an inner membrane that folds over several times to form a multi-layered structure known as cristae and an exterior membrane that encloses the organelle. The matrix, a substance that contains proteins and mitochondrial DNA, is the fluid that fills the mitochondria.

Other organelles like lysosomes are responsible for digesting and recycling toxic substances and waste. They are embedded with proteins called enzymes, which break down macromolecules, including amino acids, carbohydrates, and phospholipids.

Lysosomes are produced by a larger organelle called the Golgi complex, which manufactures other cellular machinery as well. Whenever a cell dies, it self-destructs using its own lysosomes.

............................ In this case, the statement that people who exercise for an hoour may have lower cholesterol level is HYPOTHESIS. ....................... The cholesterol level would be the DEPENDENT VARIABLE.

An hypothesis refer to a proposed statement based on prior knowledge, which is used as a starting point in scientific experimentation.

In scientific experiments, there are always two variables, independent and the dependent variable. The independent variable is the variable that is changed or controlled in a scientific experiment in order to determine its effects on the dependent variable.

The statement "Biological effects should govern the required standards of radiological protection" is true because the primary aim of radiological protection is to prevent harmful effects of ionizing radiation on living organisms, including humans.

The biological effects of radiation depend on several factors, including the type of radiation, the dose, and the sensitivity of the exposed organism. The effects may be acute, such as radiation sickness, or long-term, such as an increased risk of cancer.

Therefore, the radiation protection standards should be based on the latest scientific evidence on the biological effects of radiation, including the effects of low-level exposures and radiation doses received over a long period. The standards should also consider the potential risks associated with occupational exposure, medical radiation procedures, and environmental exposure, the statement is true.

Sure, I can help you with your question! To determine if you have bought enough dozens of eggs for all the contestants who have registered for the race in Python, you can use the following code:```pythoneggs_needed = dozens_needed = eggs_needed // 12if eggs_needed % 12 != 0:  

dozens_needed += 1print("You need to buy at least", dozens_needed, "dozen eggs.")```

Here's how the code works:

1. The `input()` function is used to ask the user how many eggs are needed for the race. The value entered is converted to an integer using the `int()` function and stored in the `eggs_needed` variable.

2. The number of dozens of eggs needed is calculated by dividing the number of eggs needed by 12 using the `//` operator, which performs integer division (i.e., it returns the quotient without the remainder). The result is stored in the `dozens_needed` variable.

3. If the number of eggs needed is not a multiple of 12 (i.e., there is a remainder), then one extra dozen of eggs is needed to make up for the remaining eggs. This is accounted for by adding 1 to the `dozens_needed` variable.4. Finally, the result is printed out using the `print()` function, which displays a message telling the user how many dozens of eggs they need to buy.
