On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.
Answer:
In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.
However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.
The thyroid gland will be mostly affected in this case. The element Iodine is
the major precursor which is involved in the formation of two hormones.
Thyroid hormonesTriiodothyronine (T3)Thyroxine (T4).When an individual is exposed to radioactive iodine , it alters the production
of the hormones which leads to series of effects such as:

Answer:
Personalized genomic medicine
Explanation:
Personalized genomic medicine is a field that uses genomics data to develop personalized technologies and therapies for clinical care. All people share a sequence homology level higher than 99%; however a very small fraction of the genome (lesser than 1%) contains genetic polymorphisms among individuals, and this variation is associated with the likelihood of suffering diseases, either by increasing or by reducing disease susceptibility. Personalized genomic medicine first identifies genetic variations and then develops new strategies and personalized drugs to treat genetic disorders.
Draw a cross section of a peach, and label the structures. What parts of the flower give rise to these structures
Answer:
exocarpo is synonymous with exocarp
endocarpo is synonymous with endocarp
mesocarpo is synonymous with mesocarp
semilla is synonymous with seed
Explanation:
In phase one, the plant's ovary begins to grow abruptly, this is where the embryo and endosperm affect their size, but if this ovarian growth is interrupted by an external factor, it determines the size of the future.
Then, the embryo and the endosperm could grow and undergo a process called sclerification, which is the hardening of the interior of the fruit, that is to say, the future formation of the seed or vulgarly called "pit". .
After this, the mesocarp, which is what is called the fleshy body or subglobose edible drupe, begins to grow.
The growth of the mesocarp is what gives the volume, weight and body to the fruit, so that after maturation it exceeds the strength of the branch and it falls from the tree.
why cells are sometimes called the building block of life?

Most physical characteristics are inherited. Scientists have discovered several genes that contribute to human fatness, particularly genes that regulate the production of specific ____________ , such as ____________ , which stimulates hunger, and ____________ , which reduces hunger.
Answer:
hormones; ghrelin; leptin.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific physical characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
A gene can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Over the years, scientists have discovered several genes that are known to contribute to human fatness (body weight), especially genes that are saddled with the responsibility of regulating the production of specific hormones, such as ghrelin, which stimulates hunger, and leptin, which reduces hunger.

B. Pillar cells, lamellae, gills, respiratory system, fish
C. Pillar cells, lamellae, gills, respiratory system, cat
D. Lamellae, gills, respiratory system, fish, pillar cells
Answer:
B
Explanation:
Cats Dont have gills so rule out C. The body has to be the end so it would be B starting from Pillar cells to fish
Biological structures are arranged based on the level of the organization. The order of organization from smallest to largest is pillar cells, lamellae, gills, respiratory system, and fish. Thus, option B is correct.
What is the level of organization?
The level of organization is the arrangement of the structures based on the level of complexity. It starts from the most simple to the most complex structures. It starts with an atom and ends in an ecosystem.
Pillar cells are the simplest level that comprises the fundamental unit made of molecules. They together make the tissues or the lamellae in the fish. The tissues or the lamellae group together to make the organ and gills.
The gills combines with the other organs to make the organ system like the respiratory system, which together with various organ system makes the fish the makes a complete organism.
Therefore, the order of the organization starts with pillar cells and ends at fish.

fur color in mice is affected by a single gene the gene for fur color has two alleles: b that causes dark brown fur and b that causes light brown fur. What is or could be the genotyes of a mouse with dark brown fur
Answer:
(BB) or (Bb)
Explanation:
Given that (B) allele , is responsible for fur that is dark brown, and (b) allele is responsible for fur color that is light brown, the dominant allele is (B) allele for dark brown fur. Dark brown fur allele would always express itself over the recessive allele, (b).
For a mouse that has dark brown fur, the possible genotype it could have is either (BB) => 2 dominant allele, or (Bb) => 1 dominant allele and a recessive allele. The dominant allele would always express itself even in the presence of the recessive allele.

Which enzyme is used in gluconeogenesis, but NOT in glycolysis? Group of answer choices PEP carboxykinase enolase (interconverts 2-phosphoglycerate and phosphoenolpyruvate)
Answer:
PEP carboxykinase
Explanation:
PEP carboxykinase is also known as Phosphoenolpyruvate carboxykinase. It is an enzyme which is used for the production of glucose from non-carbohydrate carbon substrates. This enzyme is used only in gluconeogenesis not in glycolysis because this enzyme helps in the production of glucose while glycolysis is a process in which the glucose break down into pyruvate and ATP molecules.

What are the phagocytes cell in the skin
Answer: The mononuclear phagocyte system (MPS), which includes macrophages and dendritic cells, has also been implicated in the regulation of skin salt homeostasis and blood pressure [35]
Explanation:
Answer:
The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.
When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.

Both plants are pure-breeding. All the offspring have pink flowers. What allele relationship does this display? codominance multiple alleles incomplete dominance pleiotropy
C. Incomplete dominance.
Explanation:
Incomplete dominance is the blending of alleles. If a plant with red flowers and a plant with white flowers produce offspring, then the flowers will be pink. Red and white mixed together will be pink, the alleles blended.
Codominance is where both traits are present, no blending occurs. If a plant with red flowers and a plant with white flowers produce offspring, the flowers will be both white and red. The flower may be white with red spots, or vice versa. Both alleles are present in the flower.
In this case, it is incomplete dominance, as the offspring is a mix of the parents. The alleles blend and the offspring is pink.
