Answer:

Recessive disease mutations are much more common than those that are harmful even in a single copy, because such "dominant" mutations are more easily eliminated by natural selection.

Answer:

(a) stabilizing selection

Explanation:

Sickle-cell anaemia is a recessive disorder caused by the presence of two recessive alleles "s", so the genotype is "ss". This disorder is characterized by sickle haemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle haemoglobin. But pathogen that causes malaria affects only normal haemoglobin, so heterozygous individuals will have half of the haemoglobin resistant to the pathogen and those individuals are resistant to malaria.

Stabilizing selection favours heterozygotes Ss,  disruptive selection favours dominant (SS) and recessive (ss) homozygotes, while directional selection favours dominant (SS) or recessive (ss) homozygotes. Since in this example, people with genotype Ss (heterozygotes) are at an advantage, then this is an example of stabilizing selection.

Answer: If you take high doses of Adderall for a long time, your brain may become dependent on the drug and eventually produce less dopamine.

Explanation: Adderall as we know it today owes its origins to accident. In the late 1920s, an American chemist named Gordon Alles, searching for a treatment for asthma, synthesized a substance related to adrenaline, which was known to aid bronchial relaxation.

Intricate molecules make up proteins.

The way a protein folds up determines the distinct three-dimensional form that it has. It cannot do its task in the cell if it does not fold up into the proper shape. Amino acid linkages, which are dispersed along the protein molecule, are what give a protein its shape. The bond cannot form if the incorrect amino acid is present, preventing the protein from adopting the proper shape and performing its function. For instance, the illness sickle cell anemia is brought on by a single fatal error in the amino acid sequence of the hemoglobin molecule!

Proteins are made from chemical 'constructing blocks' called amino acids. Your body uses amino acids to construct and repair muscle mass and bones and to make hormones and enzymes.

They also can be used as an power source. you can without problems meet your day by day protein needs via following the Australian nutritional recommendations.

Proteins are big biomolecules and macromolecules that contain one or extra lengthy chains of amino acid residues.

As the skateboarder moves, several energy transformations take place within their body. Some of the energy transformations include:

1. Chemical energy to kinetic energy: When the skateboarder pushes off the ground, the energy stored in the chemical bonds of their muscles is converted into kinetic energy, which is responsible for their motion.

2. Kinetic energy to gravitational potential energy: As the skateboarder moves up a ramp, their kinetic energy is converted into gravitational potential energy.

3. Gravitational potential energy to kinetic energy: When the skateboarder moves down the ramp, the gravitational potential energy is converted back into kinetic energy.

4. Kinetic energy to thermal energy: As the skateboarder moves, they also experience frictional forces which convert some of their kinetic energy into thermal energy.

5. Chemical energy to thermal energy: The continuous movement of the skateboarder requires the energy stored in their muscles to be converted into thermal energy, which is released as heat.

I hope that the assistance I provided was helpful.

The motion of the skateboarder is powered by energy transformations that occur within their body. As the skateboarder moves, their body converts stored chemical energy (from food) into kinetic energy, which is the energy of motion. This conversion happens through a series of complex biochemical processes that occur within the skateboarder's muscles.

When the skateboarder pushes off the ground, their leg muscles contract, converting chemical energy stored in the form of ATP (adenosine triphosphate) into kinetic energy as the legs move and the skateboarder accelerates. As the skateboarder continues to move, the muscles in their body work together to maintain balance and control, converting chemical energy into kinetic energy and potential energy as the skateboarder jumps, turns, and performs tricks.

Additionally, the skateboarder's body also experiences other forms of energy transformation during this process. For example, as the skateboarder moves, their body generates heat through metabolic processes, which is a form of thermal energy. The skateboarder also loses energy through friction with the ground and air resistance, which is converted into heat and sound energy.

In summary, the motion of the skateboarder is powered by a series of complex energy transformations that occur within their body. These transformations involve the conversion of stored chemical energy into kinetic and potential energy, as well as the generation of heat and sound energy through friction and air resistance.

City planners faced with the question of balancing concerns regarding mosquitoes in wetland restoration projects need to consider both the potential benefits and risks involved. On one hand, mosquitoes can serve as a food source for birds and contribute to the biodiversity and ecological balance of the wetland ecosystem.

They play a role in supporting the bird population and enhancing the natural beauty of the park. These aspects can be important factors in promoting environmental sustainability and attracting visitors to the area. On the other hand, there are legitimate concerns about the potential risks associated with mosquitoes, particularly in terms of disease transmission. While malaria is not typically a concern in the United States, other mosquito-borne diseases such as West Nile virus and Zika virus may pose risks to public health. As migration patterns change and more people move from regions where these diseases are prevalent, the potential for transmission could increase.

To strike a balance, city planners should consider implementing measures to mitigate the risks associated with mosquitoes while maximizing the benefits of wetland restoration. This can include implementing mosquito control strategies such as monitoring and targeted insecticide use, creating habitats for natural predators of mosquitoes, and providing education and awareness programs for the public. By adopting a comprehensive approach that addresses both ecological and public health considerations, city planners can create a wetland restoration project that balances the promotion of biodiversity and natural beauty with the protection of public health.

Osteoclasts are responsible for aged bone resorption and osteoblasts are responsible for new bone formation.

Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity.

The primary role of osteoblasts is to lay down new bone during skeletal development and remodelling. Throughout this process osteoblasts directly interact with other cell types within bone, including osteocytes and haematopoietic stem cells.

The area of the osteoclast next to bone forms a “ruffled border” consisting of multiple infoldings of the osteoclast cell membrane. It secretes acid and proteases across the ruffled border.
