The dry sand feels hot due to its low thermal conductivity and low specific heat, causing it to rapidly warm on the surface. The wet sand feels cooler due to the higher specific heat and thermal conductivity of water, in addition to evaporative cooling. The lemonade warms up due to thermal equilibrium, reaching the temperature of the surrounding air.
Understanding Thermal Phenomena at the Beach:
Dry sand feels hot to Kristen's feet because sand has a low thermal conductivity, which means it does not distribute heat well. The heat from the sun stays at the surface, causing the top layer to become much hotter than the lower layers. This is also impacted by the sand's low specific heat, causing it to heat up quickly when exposed to sunlight.
Wet sand feels cool because water has a higher specific heat and a better thermal conductivity than sand. As a result, the heat is absorbed more uniformly throughout the wet sand and water, and the energy from the sun is partly used to evaporate water, which has a cooling effect due to the energy required for the state change from liquid to gas.
Kristen's can of lemonade becomes warm due to thermal equilibrium. The can's temperature adjusts to match the surrounding air temperature under the umbrella, which is warmer than when she initially took the drink out of the ice chest.
An example of thermal equilibrium in this scenario is the warm can of lemonade which has reached the same temperature as the surrounding air under the umbrella after being left out for an hour.
List the 6 levels of ecological organization – starting with
the term used for an individual living thing, and ending
with the term that represents what the Earth is. How is the
organism you chose in the last lesson a part of each of the
levels? Example: LION- one lion is an individual; A group
of LIONS are a population, etc. (6 pts)
Answer:
organism, population, communities, ecosystem, and biome; excluding biosphere from the list.....or population, community, ecosystem, and biosphere.
Explanation:
brainliest???
The six levels of ecological organization include organism, population, community, ecosystem, biome, and biosphere. These represent levels from an individual living thing to the broadest scope of all ecosystems on Earth. Any organism you choose will fit into these levels in a similar manner.
Explanation:The six levels of ecological organization, starting from the smallest unit to the largest, are:
Organism: This is an individual living thing, such as a lion. Population: This refers to a group of the same species that lives in the same area, like a pride of lions in the same savannah. Community: This includes all the different species that live together in a habitat, like lions, zebras, and elephants in the savannah. Ecosystem: This constitutes both the living (biotic) and non-living (abiotic) factors of a particular environment. For instance, a savannah ecosystem would include all its animals, plants, weather, and so forth. Biome: This is a major ecological community spread over a large area, for instance the Savannah biome, which has similar weather, animal, and plant life across multiple continents.Biosphere: This is the part of the earth where life exists, including all biomes and ecosystems. Thus, our lion from the earlier example is part of our global biosphere.
The organism you chose in the previous lesson would fit into these levels in a very similar manner to our lion example.

Incomplete dominance can be observed in snapdragons. Snapdragon flowers
that have two RR alleles have a red phenotype. Snapdragon flowers with arr
have a white phenotype. Snapdragon flowers that are Rr are pink.
11. Fill in the two Punnett squares in diagram at right.
12. This is a non-Mendelian trait, but how could this be different if the trait
was Mendelian?
Incomplete dominance is observed in snapdragons, where the phenotype of the flower is determined by the combination of alleles. The Punnett squares show the possible genotypes and phenotypes of the offspring. If the trait were Mendelian, there would be distinct phenotypic differences between the homozygous genotypes.
Explanation:Incomplete dominance is observed in snapdragons, where the phenotype of the flower is determined by the combination of alleles. In this case, snapdragons with two RR alleles have a red phenotype, those with aa alleles have a white phenotype, and those with Rr alleles have a pink phenotype.
The Punnett squares can be filled out by crossing a RR individual with an rr individual or crossing two Rr individuals. In the first case, all offspring will be Rr (pink phenotype). In the second case, there will be a 1:2:1 ratio of RR:red, Rr:pink, and rr:white offspring.
If the trait were Mendelian, the dominant allele would completely mask the recessive allele, resulting in a clear-cut phenotypic difference between the two homozygous genotypes RR and rr, without any intermediate phenotype.

Key Concepts:
Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.

c. Oil is burned to heat water into steam in order to turn turbines that generate electricity.
d. The electronic signs along the highway are run by solar power.
PLEASE HELP
Answer:
c
Explanation:
the answer is c because oil is a non renewable resource due to the time it takes to make
Natural gas is unquestionably a much cleaner non-renewable energy source than coal, but it still contributes to almost a third of the nation's greenhouse gas emissions. Thus, option C is correct.
What is the significance of non-renewable resource?A resource is nonrenewable if it is consumed more quickly than it can replenish. A nonrenewable resource's supply is limited, which means it is difficult to refill. The Earth itself is used to harvest non-renewable resources.
Nuclear power, natural gas, coal, and oil are examples of nonrenewable energy sources. The fact that we now rely on these resources to provide the majority of our energy needs makes the fact that they cannot be replenished after they are depleted a serious issue for humanity.
Therefore, oil is burned to heat water into steam in order to turn turbines that generate electricity, best describes the use of a non-renewable resource.

which of the following is not generally considered a threat to endangered species
Answer:
B.) Competition for mates
Explanation:
Generally, species become endangered in the first place has to do with humans. If you analyze the other options, they each typically are caused by humans.
Poaching is illegal hunting or capturing of animals (endangered or not)
Clear-cutting is the same as deforestation, and causes habitat loss
Introduction of non-native species is typically caused by people who bring pets from other countries back to their native countries.
A competition for mates isn't normally something that causes a species to go endangered or extinct. The other options are much more threatening to this!

1. scientists had identified a pattern in the moths that they thought was important. What was the pattern?
2. The classified identified several factors that could affect populations. One of those factors was abiotic. What are some abiotic factors that you think would be affecting the moth population.
Answer:
1. They had predators both at night and through the day, and that they tried to hide and rest on trees but were not very hidden.
2. The chemicals released by the female moths to mate and lay eggs is an important abiotic factor in which affected the population. The more the chemical was released, the more it led to eggs being laid and reproducing.
Explanation:
The moth symbolizes rebirth, change, transformation, resurrection, and the power of regeneration in Native American mythology. In fact, butterflies and moths both hold a significant position in the Native American culture.
How did moths evolve?
Scientists have long attributed these insects' rich variety to their close connections with other organisms. Butterflies, they hypothesized, evolved in tandem with the plants they fed on, and moths developed sophisticated defense mechanisms in response to bats, their main predators.
What is the cycle of a moth?There are four stages of the moth life cycle: eggs, larvae, pupa/cocoon, and adult. Each stage represents a significant step in a moth's lifespan.
What was causing the change in the moths?Genetic ChangesMoths passed their color to the next generation. Eggs from light moths developed into light moths and dark moth eggs turned to dark adults. The dark color was caused by a mutation in the DNA of a single moth, and the mutated gene had been passed to all its offspring.
How abiotic factors affect moth populations?Environmental factors that influence populations are divided into two categories – abiotic and biotic factors. Abiotic factors refer to the non-living physical and chemical elements found in an ecosystem such as rainfall, temperature, pH, sunlight, shelter and day length.

Chomozygous
D brown
Answer:
homozygous
Explanation:
when an individual both copies of a given gene have the same allele
In genetics, an individual who receives one dominant allele and one recessive allele is said to be heterozygous for that gene.
Explanation:In genetics, an individual who receives one dominant allele and one recessive allele is said to be heterozygous for that gene. The dominant allele is represented by an uppercase letter, and the recessive allele is represented by a lowercase letter. In this case, since Mark received one dominant allele for brown hair from his father and another dominant allele from his mother, his genotype can be described as heterozygous.
