Answer:
Two dominant alleles aren't required for it to be expressed as the phenotype. however, two recessive alleles are necessary for the characteristic to be expressed as the phenotype
Answer:
Glucose
Explanation:
The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.
Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.
Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.
The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.
Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.
Answer:
The correct answer will be option-A
Explanation:
Biodiversity refers to the diversity of the biological entities present in an ecosystem. Biodiversity has a wide spectrum which not only includes the number of the diversity of the organism but also the interaction between them.
The biodiversity is assessed to study the changes that are taking place in an ecosystem, to study the causes and how the changes affect the human well being.
The assessment decisions ignore the personal interests and the biasness as the aim of the approach is not fulfil the personal needs but to maintain sustainable management of the ecosystem.
Thus, option-A is the correct answer.
Neurons in the hypothalamus regulate the activity of secretory cells in the anterior pituitary gland by releasing hormones. Pituitary gland basically store the hormones which is produce by the hypothalamus.
Hypothalamus connect the nervous and endocrine systems by way of the pituitary gland. Both are connected directly to the pituitary gland by a thin stalk which is called infundibulum.
Its main function is to secrete releasing hormones and inhibiting hormones that stimulate the production of hormones in the anterior pituitary. FSH and LH both are produce and secret gonadotropins which regulated by the hypothalami releasing hormone, GnRH. These are the releasing hormones which control the release of another hormone.
