Jeremiah is on a school trip to a forest preserve. According to the urban heat island effect, as Jeremiah leaves the city and heads toward the nature preserve, the temperature should (first drop-down) . That's because large cities (second drop-down) more heat than rural areas. When Jeremiah arrives at the preserve, he immediately notices the effects of solar radiation. The blacktop in the parking lot feels (third drop-down) the green grass where his class will eat their picnic lunch. →First drop -down options 1. Remain the same 2. decrease 3. increase Second drop-down options 1. absorb 2. transmit 3. reflect third drop-down options 1. hotter than 2. cooler than 3. same temperature as←

Answers

Answer:

2. decrease

3. reflect

1. hotter than

Explanation:

As Jeremiah will move towards nature preserve the temperature will decrease because heat once absorbed as energy is reflected by a temperature rise and large cities reflect more heat than rural areas. It is so because large cities have buildings and other structures that absorb fore heat and reflect more heat.

The blacktop will be hotter than the green grass because blacktop reflects more heat in comparison to green grass.

Hence, the correct answer is:

2. decrease

3. reflect

1. hotter than

Answer:

decrease

reflect

hotter than

Answers

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.

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.

Answers

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.

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.

You cross a plant with red flowers with a plant with white flowers. Both plants are pure-breeding. All the offspring have pink flowers. What allele relationship does this display? codominance multiple alleles incomplete dominance pleiotropy

Answers

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.

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

Answers

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.

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.

Answers

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.

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.
