which practices in agriculture and animal domestication demonstrate a rudimentary understanding of heredity and genetics? when foraging for edible plants, gatherers avoided plants that produced poisonous berries. to prevent injury to other livestock, ranchers removed the horns from bulls after birth. nomads selected the fastest horses for breeding. primitive societies were more likely to kill wolves that were too aggressive and keep the less aggressive ones as pets and hunting companions. farmers planted seeds from trees that produced the largest, sweetest fruits and not from trees that produced the smallest or inedible fruits.

6CO² + 6H2O = C6H12O6 + 6O2

Important note: Do NOT write an equal sign whenever you write it, make sure it's an arrow, otherwise the answer will be wrong. And if you use and equal sign in an exam, then you will get 0 marks. The reason I used an equal sign was because I couldn't find an arrow on my keyboard.

If solution A is isotonic when compared with solution B, it means that the concentration of solutes in both solutions is the same. Therefore, solution B is also isotonic.

Hypertonic and hypotonic solutions:

If solution B had a higher concentration of solutes, it would be hypertonic, and if it had a lower concentration of solutes, it would be hypotonic. The cell membrane plays an important role in maintaining the balance of solutes between the cell and its environment. If the solution outside the cell is hypertonic, water will move out of the cell through exosmosis, causing the cell to shrink and undergo plasmolysis.

Plasmolysis is a process in which cells lose water in a hypertonic solution, causing the cell membrane to shrink away from the cell wall. Electrolytes also play a crucial role in regulating the concentration of solutes in the body. In this case, since solution A and solution B have the same concentration of solutes, they are both isotonic solutions. An isotonic solution is a solution with the same concentration of solutes as another solution.

Explanation:

C) Reduction of temperature and pressure is likely to cause the precipitation of lime out of a water solution.

To precipitate limestone add the lime to water to form calcium hydroxide to from hydrated lime or slake. Remove additional impurities from the slaked lime. Combine the solution with carbon dioxide and slaked lime.

In general ,When limestone is heated, calcium oxide and carbon dioxide gas are formed. When carbon dioxide gas is passed through freshly prepared lime water, the solution turns milky due to the formation of calcium carbonate, that is not soluble in water.

Hence, C is the correct option

The correct sequence for making a common transcription factor in the RNA polymerase II promoter, then the correct answer is option B, TFIID, TFIIA, TFIIB, TFIIF, TFIIH.

General transcription factors are a group of proteins that are required for the transcription of protein-coding genes in eukaryotes. They assemble at the promoter region of a gene, which is the sequence of DNA that signals the start of transcription. The assembly of general transcription factors at the promoter is a step-by-step process that is essential for the initiation of transcription.

The first general transcription factor to bind to the promoter is TFIID, which recognizes and binds to the TATA box, a sequence of DNA found in many promoters. Next, TFIIA and TFIIB bind to the promoter, followed by TFIIF and RNA polymerase II. Finally, TFIIH binds to the complex, completing the assembly of general transcription factors at the promoter.

Therefore, the correct order of general transcription factor assembly at an RNA polymerase II promoter is TFIID, TFIIA, TFIIB, TFIIF, TFIIH.

The chromosome number of the below-illustrated diploid cell is 2n=4.

The diploid cell is a cell with a pair of homologous chromosomes that have the same genes, and therefore, is also referred to as 2n (two haploid sets of chromosomes). These cells are present in organisms that reproduce sexually and are called somatic cells.

The haploid cell, in contrast, has only one set of chromosomes, and therefore, is referred to as n. In human, the haploid number is 23, and the diploid number is 46. The chromosome number of the below-illustrated diploid cell is 2n=4.

Explanation:

Dogwood and oak trees are two kinds of plants found in a forest. These trees and other forest plants get the energy they need for making food from Sun that is the solar energy which the plants use to produce sugar. Sun is the basic source that is used for photosynthesis.

Glucose is the end product of photosynthesis which is the ultimate source of energy for plants.

Photosynthesis usually takes place in 4 steps where the first step is the absorption of light where the light from sun is absorbed by stomata and the various reactions that take place in the light are called as the light reactions.

Transfer of light helps to electrons to excite and the excitation of electrons helps to make new products various phosophorylation reactions that is the production of ATP is taking place or the lysis of the product is taking place as well.

The first method, conservative replication, had the DNA strand completely conserved. Two old DNA strands stuck together, and two new DNA strands were synthesized and stuck together. The old and new DNA did not bind to one another. Another method, dispersive replication, did have old and new DNA binding to each other.

The conservation of genetic information during DNA replication is important, as DNA replication is the process by which cells make copies of their genetic material that pass on to the next generation.

The conservation of genetic information during DNA replication is important for maintaining the stability of the genome, preventing the accumulation of harmful mutations, and allowing evolution to occur. The genetic information must be accurately passed down from generation to generation and is also useful adapt to changing environmental conditions.

DNA replication is considered semi-conservative d. the new double helix has one strand of original DNA and one new strand.

DNA replication is the process of doubling the DNA chain before cell division occurs. By the mechanism of synthesizing a new DNA strand by adding complementary nucleotides to the template strand.

Semiconservative replication is a biologically significant model of DNA replication proposed by Watson and Crick. The semiconservative theory, which states that the double helix strands split into a single helix, then form a new pair of complementary strands. During semiconservative replication, one old DNA strand serves as a template to form a new strand. DNA replication is called semi-analysis because DNA produces a new strand after synthesizing the old strand.

Blood doping frequently results in an increase in the level of hemoglobin in the blood. An oxygen-carrying protein found in blood is called hemoglobin. The red blood cells of an athlete who uses blood doping should absorb more oxygen and will get less.

Blood doping is a type of doping in which more red blood cells are added to the bloodstream to improve sports performance.

An athlete's aerobic capacity (VO2 max) and endurance can be enhanced by having more of these blood cells, since they transport oxygen from the lungs to the muscles.

Athletes in a range of endurance sports, such as swimming, cycling, and skiing, use blood doping.

Some people view the use of plasma injections by athletes in other sports as a sort of blood doping because they help them recover physically faster between competitions.

True. The facial bones play a critical role in protecting the delicate internal structures of the face, including the eyes and the upper respiratory tract.

The bones of the face are specially designed to provide a strong and stable framework that can withstand external forces and protect the underlying soft tissues.

The orbital bones, for example, form the protective bony socket that houses and protects the eyes. These bones are shaped in a way that helps to prevent injury to the eyes from impacts or sudden movements. Similarly, the bones of the nose and mouth form a protective barrier around the nasal and oral cavities, which are essential for breathing, eating, and speaking.

The facial bones also provide attachment points for muscles that are involved in facial expression, chewing, and other important functions. Without the structural support provided by these bones, the face would be much more vulnerable to injury and damage from external forces.

Overall, the facial bones are a crucial part of the body's overall defense against injury and illness. By providing a strong and stable framework for the face, these bones help to protect the vital internal structures of the eyes, nose, mouth, and upper respiratory tract, ensuring that these organs can function properly and remain healthy over time.
