The best biological term to describe a chain of enzyme controlled reactions is metabolic pathways. Metabolic pathways are a series of enzyme-catalysed reactions that convert a substrate into a product. These pathways are essential for the metabolic processes of living organisms, and are usually regulated by a complex network of enzymes and other regulatory proteins. Phosphorylation pathways involve the transfer of phosphate groups from one molecule to another, and enzyme metabolism is a term used to describe the chemical changes caused by enzymes.

Thyrotropin-releasing hormone is released by the hypothalamus, thyroid stimulating hormone is released by the pituitary, and thyroid hormones T3 and T4 are released by the thyroid gland. Individuals with Kallman Syndrome will have a disruption in this endocrine axis.

Kallmann Syndrome is characterized by delayed or absent puberty as well as a poor sense of smell. This condition is a type of  hypogonadotropic hypogonadism, which is caused by a lack of product of certain hormones that regulate sexual development. These hormones are typically produced in the hypothalamus, a region of the brain. Males with hypogonadotropic hypogonadism constantly have a undescended testes( cryptorchidism). Most affected individualities don't develop secondary coitus characteristics during puberty, similar as facial hair growth and voice heightening in males, the launch of yearly ages( period) and bone development in ladies, and a growth spurt in both relations.

Pedigrees with autosomal recessive traits will indicate an equal number of affected males and females, but pedigrees of X-linked recessive traits will reveal that the majority of affected individuals are male.

Pedigree with autosomal recessive trait shows equal frequency of affected males and females, while kindreds with X-linked recessive trait show that most affected individuals are male. All females affected by the X-linked recessive trait have an affected father. Also, a mother with an X-linked trait can have an affected son regardless of the father's genotype, but both parents must be carriers. For example, for X-linked recessive traits, males are affected much more often than females.For autosomal traits, both males and females can be affected equally (usually in equal proportions).

Some protists are able to live in air by possessing various adaptations that allow them to survive in this environment. For example, some protists have a protective coat of mucilage or a thick cell wall that prevents desiccation, or drying out, in the air. Others have developed the ability to move quickly, such as through the use of flagella or cilia, which allows them to move away from adverse conditions. Additionally, some protists are able to form spores, which are resistant structures that can survive in harsh environments, including in the air. These spores can later germinate and develop into new individuals when conditions become more favorable.

Good land and production practices cannot help increase greenhouse gas emissions.

Greenhouse gas emissions are the gases that trap heat in the atmosphere, thereby warming the planet. Greenhouse gas emissions are primarily caused by human activities such as burning fossil fuels, deforestation, and agriculture. Good land and production practices can actually help reduce greenhouse gas emissions.

For example, conservation agriculture practices, agroforestry, and sustainable land management practices can help sequester carbon in the soil, reducing the amount of carbon dioxide in the atmosphere.

Similarly, sustainable livestock management, reducing food waste, and increasing the use of renewable energy sources can also contribute to reducing greenhouse gas emissions.

The r-selected organisms are better suited for environments that frequently experience extreme and unpredictable environmental swings.

The idea of K- and r-selected species had been successfully applied to population research during the second half of the 20th century. The idea applies to a species' habitat, behavior, and reproductive techniques as well.

R-selected species, as opposed to K-selected species, have a lot of little offspring (hence their r designation). In unexpected or dynamic circumstances, this tactic is frequently used. R-selected animals do not provide long-term parental care, and the young are generally developed and self-sufficient upon birth. Marine animals like jellyfish and plants like dandelion are examples of r-selected species. Small dandelion seeds travel great distances in the wind, and several seeds are produced at once to make sure that at least part of them make it to a friendly environment. Given their little energy content, seeds have limited chance of surviving when they fall into hostile settings.

Gram-positive bacteria have a thick peptidoglycan layer in their cell walls. When stained with crystal violet and iodine, the peptidoglycan layer will retain the dye, resulting in a purple color.

Gram-negative bacteria have a thinner peptidoglycan layer and an outer membrane containing lipopolysaccharides. When stained with crystal violet and iodine, the thinner peptidoglycan layer will not retain the dye, and the outer membrane will not be affected. The result is that the cell appears pink or red.

Explanation:

If a consumer loses 70% of the 2000J energy in their food as waste heat, that would be 70/1002000 = 1400 J

And if 20% in their waste products, that would be 20/1002000 = 400 J

So the total amount of energy lost as waste heat and in waste products is 1400 J + 400 J = 1800 J
