Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.
Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

A student created a table to compare animal adaptations. Based on the table, which
animal has a behavioral adaptation, and how does it give the animal an advantage?
Animal Adaptation
Duck Webbed feet
Squirrel Collects and stores food
The duck, because the behavioral adaptation allows it to catch prey.
The duck, because the behavioral adaptation helps it survive the environment.
The squirrel, because the behavioral adaptation provides food during winter.
The squirrel, because the behavioral adaptation to have more offspring.
Answer:
B
Explanation:
Ducks have the webbed feet so, they could swim in the water so they don't drown. That is animal adaptation to the environment.
Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.
What is behavioral adaptation?The behavioral adaptation of collecting and storing food is an important survival strategy for many animals, including squirrels. During times of abundance, such as the fall months, squirrels will collect and store food, such as nuts and seeds, in order to have a food source during times of scarcity, such as the winter months. This allows the squirrel to survive and avoid starvation during times when food is less readily available.
Hence, Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

15. The elements in group_
are the most reactive nonmetals.
16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.
write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers
Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.
Answer:
Above 37 million
Explanation:
Explanation in picture below
Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.
Thus, Bacterial population growth occurs geometrically or exponentially: in each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.
The relationship shows that the average generation time is constant and the growth rate of the bacterial population is proportional to the number of bacteria at any given time.
This relationship is valid only during the period when the population grows exponentially, ie. in the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.
Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Write 5-6 sentences that explains roles of Heredity and probability.
Answer:
Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.

The answer here would be A. The organism is a singular thing, so it should be first. The population comes next - it is all the same type of organism living in one ecosystem. Next is community - this is all the living organisms in the area. Lastly, there is the ecosystem - the organisms, their habitats, and everything else.
