The correct option is the first one, "Gases in the atmosphere absorb and trap Earth's heat." Some gases such as CO2 (carbon dioxide) and CH4 (methane) absorb a lot of heat that is reflected from the earth. Thus, they cause major changes in earth's climate as their concentration rises.

Angelman syndrome is characterized by intellectual disability, severe speech impairment, ataxia, seizures, and a happy demeanor. Prader-Willi syndrome involves hypotonia, hyperphagia, obesity, intellectual disability, behavioral problems, and short stature.

Angelman syndrome and Prader-Willi syndrome are two distinct genetic disorders that are often discussed in the context of epigenetic inheritance. Both conditions result from abnormalities in a specific region of chromosome 15, but they have opposite effects due to differential genetic imprinting.

Angelman syndrome is characterized by developmental delays, severe intellectual disabilities, speech impairments, and motor coordination problems.

Individuals with Angelman syndrome often exhibit a happy and excitable demeanor, with frequent episodes of laughter and a fascination with water. They may also experience sleep disturbances, seizures, and a lack of speech development.

On the other hand, Prader-Willi syndrome manifests with distinct symptoms such as hypotonia (poor muscle tone) during infancy, hyperphagia (insatiable appetite) leading to obesity, developmental delays, learning difficulties, and behavioral challenges.

Individuals with Prader-Willi syndrome often have a compulsive need for food and struggle with weight management. They may also experience hormonal imbalances, growth hormone deficiency, and behavioral issues such as temper tantrums and obsessive-compulsive behaviors.

Epigenetic inheritance refers to the transmission of information from one generation to another that affects gene expression without altering the underlying DNA sequence.

In the case of Angelman and Prader-Willi syndromes, these conditions result from epigenetic changes, specifically imprinting, in the chromosomal region involved. Imprinting refers to the process by which certain genes are marked or silenced based on their parental origin.

In Angelman syndrome, the paternal copy of the UBE3A gene is deleted or silenced, leading to a lack of functional UBE3A protein in the brain. In Prader-Willi syndrome, the maternal copy of the same gene is affected. These imprinted genes play critical roles in brain development and function, leading to the distinct symptoms observed in each disorder.

It is important to note that while both Angelman and Prader-Willi syndromes are considered examples of epigenetic inheritance, the underlying mechanisms and specific epigenetic changes involved are complex and continue to be studied.

The best example of gene flow among the following is that the (b) wind blows pollen from one population of plants to another and cross-fertilization occurs.

In higher plants, cross-fertilization occurs when pollen grains from one plant's cones or flowers are transmitted to another plant's cones or flowers that are producing eggs. Cross-pollination can take place via wind, as it does in conifers, or by symbiotic partnerships with various creatures (such as bees, certain birds, and bats) that spread pollen while consuming nectar from one plant to another.

Animals use a wide variety of cross-fertilization techniques. The majority of animals that reproduce in watery situations externally fertilise after both the male and female have lost their sex cells into the water.

The correct option is B ; Translocation of SRY to an autosome of a 46, XX individual , The SRY gene codes for the protein known as the sex-determining region Y protein.

This protein is involved in the formation of male-typical sex, which normally follows a certain pattern based on an individual's chromosomes. Each cell in a person typically contains 46 chromosomes.

The gene SRY (sex determining region of the Y), situated near the distal end of the Y chromosome's short arm, is required for male sex determination in animals. SRY starts the chain of events that leads to the formation of a testis from an undifferentiated gonad.

In animals, the SRY gene (blue band) on the male Y chromosome governs sex determination. The presence of a Y chromosome determines sex in placental animals. Normally, female cells have two X chromosomes, whereas male cells have one.

Answer:

Scientific Theory

Explanation:

The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.

In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.

Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

If the government sets a price ceiling on dog food that is below the equilibrium​ price a shortage of dog food occurs. The correct answer is C.

When the government sets a price ceiling on dog food that is below the equilibrium price, it creates a situation where the maximum price that can be charged for dog food is lower than what would naturally occur in the market. This price ceiling prevents the market from reaching equilibrium, leading to a shortage of dog food.

Due to the lower price ceiling, suppliers are unable to charge the market price that would allow them to cover their costs and make a profit. As a result, some suppliers may choose to reduce their production or exit the industry altogether. This decrease in the quantity supplied leads to a shortage of dog food, as the quantity demanded at the lower price exceeds the quantity supplied.

Consumers, on the other hand, are incentivized by the lower price to demand more dog food. This increased demand exacerbates the shortage, as the quantity demanded exceeds the quantity supplied at the price ceiling. As a result, consumers may face difficulties in finding and purchasing dog food, leading to a shortage in the market. Therefore, the correct answer is C.

The nervous system is the complex network of nerve cells and fibers that transmits signals between different parts of the body. It is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).

The central nervous system (CNS) includes the brain and spinal cord. It is responsible for receiving and interpreting sensory information from the PNS, and for generating motor commands that are sent out to the PNS to control the body's muscles and organs.

The peripheral nervous system (PNS) consists of all the nerves and ganglia outside of the brain and spinal cord. It is further divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and transmits sensory information to the CNS, while the autonomic nervous system controls involuntary functions such as heart rate, digestion, and breathing.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
