What is an exothermic reaction?When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.
The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.
Therefore, the correct option is C.

The different forms of the beef cattle color gene are called_
The different forms of the beef cattle color gene are called "alleles"
What are alleles?Alleles are alternative versions of a gene that arise from mutations and are located at the same position on a chromosome.
In the case of beef cattle, the color of the animal is determined by the interaction of multiple genes, including the color gene. The color gene can have different alleles that influence the color of the animal's coat. For example, one allele may result in a black coat color, while another allele may result in a red coat color.
The combination of alleles that an animal inherits from its parents determines its genotype, which in turn determines its phenotype or observed traits. Therefore, the different alleles of the beef cattle color gene can result in different coat colors, patterns, and markings in the cattle population.

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

which type of specialized cells would be found in an animal’s neuvous system?
The type of specialized cells would be found in an animal’s nervous system are the cells that transmit signals around the body. The correct option is D.
What is the nervous system?The nervous system is the part of an animal's body that controls behavior and sends messages to other parts of the body. It is divided into two components in vertebrates: the central nervous system (CNS) and the peripheral nervous system. The CNS houses the brain and the spinal cord.
Neurons are specialized cells found in animals. These cells are classified as sensory neurons, interneurons, or motor neurons based on their function. They transmit signals from the body to the brain and from the brain to the body parts.
Therefore, the correct option is D. Cells that can transmit signals around the body.

Tropical rainforests have the greatest biodiversity of any type of land ecosystem how does biodiversity contribute to the sustainability of an ecosystem
Biodiversity contributes to the sustainability of an ecosystem in ways such as biodiversity, ecosystem stability, ecosystem resilience, nutrient cycling, pollination, and medicinal properties.
Biodiversity is crucial for the sustainability of an ecosystem as it plays a significant role in maintaining the functioning of ecosystems and providing a range of ecological services. In tropical rainforests, which have the highest biodiversity, the presence of numerous species of plants, animals, fungi, and microorganisms contributes to the sustainability of the ecosystem in the following ways:
Ecosystem Stability: Biodiversity helps to maintain the stability of an ecosystem by providing a balance between predator and prey populations, nutrient cycling, and decomposition.
Ecosystem Resilience: The greater the biodiversity of an ecosystem, the more resilient it is to disturbances such as climate change, natural disasters, and human activities.
Nutrient Cycling: Biodiversity helps in the efficient cycling of nutrients in the ecosystem. Different species of plants and microorganisms play a role in decomposing organic matter, recycling nutrients, and maintaining soil fertility.
In summary, biodiversity is essential for the sustainability of ecosystems. It provides ecological services that are critical for maintaining the functioning of the ecosystem and contributing to human well-being.
