Inbreeding and assortative mating are both examples of non-random mating in populations. Non-random mating occurs when individuals choose to mate with certain individuals based on specific traits, such as genetic relatedness or similarity in physical characteristics.
Inbreeding is the process of breeding closely related individuals, which can result in the expression of harmful recessive traits due to the increased likelihood of two copies of a harmful allele being inherited. This can lead to decreased genetic diversity and can be harmful to the overall fitness of a population.
Assortative mating, on the other hand, is the tendency for individuals to mate with others who are similar to themselves in certain characteristics, such as height, weight, or even behavioral traits. This can lead to an increase in homozygosity for certain traits and can have both positive and negative effects on the genetic diversity and fitness of a population.
Both inbreeding and assortative mating are examples of non-random mating and can have significant effects on the genetic makeup and fitness of a population. It is important for researchers and conservationists to understand these processes in order to make informed decisions about managing and conserving populations.

Answer:
A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map.
Explanation:
Each contour line can be defined as a closed line joining relief points at equal height above sea level. It is usually drawn on the same horizontal scale as the map, but the use of an exaggerated vertical scale is advisable to underline the elements of the relief. This can vary according to the slope and amplitude of the terrestrial relief, but is usually three to five times the horizontal scale.
antibiotic are not useful for treating the common cold because
Antibiotics are not useful for treating the common cold because the common cold is primarily caused by viral infections, not bacterial infections.
Antibiotics are medications that are specifically designed to kill or inhibit the growth of bacteria. They are not effective against viruses. The common cold is typically caused by different strains of viruses, such as rhinoviruses. Antibiotics do not have any impact on these viral infections and cannot cure or alleviate the symptoms of the common cold.
Using antibiotics unnecessarily for viral infections can have negative consequences. It can contribute to the development of antibiotic resistance, where bacteria become resistant to the effects of antibiotics, making them less effective for treating bacterial infections in the future. Therefore, it is important to reserve the use of antibiotics for bacterial infections where they are actually needed.
Instead of antibiotics, the common cold is typically managed with supportive measures to relieve symptoms. These may include rest, staying hydrated, over-the-counter medications for symptom relief (such as pain relievers or decongestants), and home remedies like warm fluids and saltwater gargles.

2 Natures of Insular Biotas?
The two natures of insular biotas refer to their isolation and unique ecological characteristics. Insular biotas are typically isolated from mainland ecosystems and have evolved in distinct ways due to their insularity.
Two natures of insular biotas are:
1. Isolation: Insular biotas, being located on islands or isolated areas, experience limited interaction with other ecosystems. This results in unique species compositions and adaptations due to the absence of certain external influences.
2. Endemism: Insular biotas often have high levels of endemism, meaning many species found in these ecosystems are unique to that specific location. This is a result of the isolation, which allows species to evolve independently from their mainland counterparts.
This isolation has led to the development of unique species and communities, as well as increased vulnerability to threats such as invasive species and habitat loss.
The insular nature of biotas also means they are often more sensitive to environmental changes, making conservation efforts crucial for their survival.

The effect of covalent modification of a protein with a phosphate group depends on the protein and the specific site of phosphorylation.
Phosphorylation of a protein can alter its function in various ways, including changing its conformation, creating new binding sites, or inhibiting its activity. Phosphorylation can induce conformational changes that affect the protein's ability to interact with other molecules. For example, phosphorylation of some enzymes can either activate or inhibit their activity by inducing a conformational change that affects their active site. Phosphorylation can also create new binding sites for other molecules, such as proteins or enzymes. On the other hand, phosphorylation can also inhibit the activity of some proteins by masking their active site or inducing a conformational change that renders them inactive. Therefore, there is no general 'rule' describing the absolute effect of phosphorylation on the function of the protein, and the effects of phosphorylation can vary depending on the protein and the site of modification.

Organisms that can make their own food using energy of the sun are called what ?
Answer:
Explanation:
organism that can make their own food using energy of sun are called autotroph and producers
Organisms that can make their own food using the energy of the sun are called autotrophs.
Autotrophs are capable of converting inorganic substances, such as carbon dioxide and water, into organic compounds, typically through the process of photosynthesis. They utilize the energy from sunlight to drive the synthesis of glucose or other energy-rich molecules, which serve as their source of nutrition.
Plants are the most well-known examples of autotrophs, as they possess specialized structures, such as chloroplasts containing chlorophyll, which enable them to capture sunlight and carry out photosynthesis. During photosynthesis, plants convert light energy into chemical energy, storing it in the form of carbohydrates, which can be used for growth, metabolism, and reproduction.
In addition to plants, certain types of bacteria, algae, and some protists are also capable of photosynthesis and are considered autotrophs. Autotrophs play a crucial role in ecosystems as they form the basis of food chains, serving as a source of energy for heterotrophic organisms that cannot produce their own food.

A 1500 iu (300 µg) dose of rhig can suppress immunization to 30ml ml of d-positive whole blood
About 30 mL of D-positive whole blood can prevent immunization with 300 g of RhIg (15 mL of packed rbc). If the gestational age is less than 12 weeks, a dose of 600 IU (120 g) can be adequate. The recommended dosages change from nation to country and even within countries depending on the foetus' development.
In North America, it is accepted that 300 g of RhIg can prevent the immunisation of about 30 mL of whole blood that has tested positive for D. For example, FMH larger than 30 mL of whole blood (for 300 g dosages) and FMH above 12 mL of RBC (for 100 g doses) both call for testing to identify larger foetal bleeds.
