How would life on earth change if there was no clean water or air?
Answer:
With no water supply, all vegetation would soon die out and the world would resemble a brownish dot, rather than a green and blue one. Clouds would cease to formulate and precipitation would stop as a necessary consequence, meaning that the weather would be dictated almost entirely by wind patterns.
are food will die then the animals will die then we would die and the earth wouldn't be green no more it will be brown and bry there will be no clouds ether or grass

trap ozone at Earth’s surface
keep Earth cool
absorb heat from the sun
Answer:
absorb heat from the sun
Explanation:
Greenhouse gases are specific type of gases that possess the ability to trap and emit heat/thermal energy in the atmosphere. They are able to do this because of their structure. Examples of greenhouse gases are carbon dioxide (CO2), methane (CH4), chlorofluorocarbon (CFC) etc and are mostly produced via anthropogenic activities.
Greenhouse gases are therefore, produced both artificially (by burning fossil fuels) and naturally and functions to absorb heat from the atmospheric surroundings.
Answer:
absorb heat from the sun

Explain how the nervous and endocrine systems work together to control the body and maintain homeostasis in a paragraph.
Answer:
Explanation:
The nervous system controls virtually all body activities, and the endocrine system secretes hormones that regulate these activities. Functioning together, the organ systems supply body cells with all the substances they need and eliminate their wastes. The glands of the endocrine system secrete hormones into the bloodstream to maintain homeostasis and regulate metabolism. The hypothalamus and the pituitary gland are the command and control centers, directing hormones to other glands and throughout the body.
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.

Where does The energy come from to heat the oceans
Answer:
the sun
Explanation:
which heats up faster
Water or air
Answer:
Air
Explanation:
Air.
Why? Because air has a much lower specific heat capacity (Heat capacity - Wikipedia) per unit mass than water. Also, air is dispersed as a gas so that in any given volume the mass of air that would fill it is only a fraction of the mass of water that would fill the same volume. Take these two factors into consideration and you see that the amount of energy it takes to raise the temperature of a volume of air by one degree is minuscule compared to the amount of energy it takes to heat the same volume of water by one degree.
The one thing that is more challenging about air is actually getting the energy into it. Water is densely packed, whereas air molecules are much more widely separated, so that presents a heat conductivity challenge. However, if we’re talking about equipment specialized for heating air (i.e. a fan forcing air over heated coils) versus equipment specialized for heating water (flat plate, coils, pumps or no pumps, whatever), energy added at the same rate to each will heat an equivalent volume of air to a greater extent (i.e. raising temperature more quickly) that it will water.

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.
In corgis, a breed of dog, short tails are completely dominant to long tails. If two long-tailed corgis have puppies, what is the percent chance of having a puppy with a short tail?
Answer:
0%
Explanation:
This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).
According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:
All ss (long-tailed) offsprings/puppies.
Based on the question asked, 0% or none of the puppies produced will have a short tail.

What is central nervous system?The central nervous system (CNS) includes the brain and the spinal cord responsible for processing information received from peripheral nervous system (PNS) to generate appropriate responses. The brain is the most complex organ of the CNS, carries various functions, including sensation, perception, movement, etc.
Sensory nerves transmit information from sensory receptors, such as those in the skin, muscles, etc. to central nervous system (CNS) and sensory nerves are activated by various types of stimuli.
Motor nerves transmit signals from the CNS to muscles, and other effectors throughout the body. These signals are responsible for activation of muscle contractions, produce movements, and other responses.
Therefore, sensory and motor nerves both work together to perform physiological functions where sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS.

Select the statement that describes the major site where antiviral action is blocked by the protease inhibitors. Select one: a. The protease inhibitors block the ability of the human immunodeficiency virus from attaching and entering the cell membrane. b. The protease inhibitors block the uncoating process of the human immunodeficiency virus by binding to protease. c. The protease inhibitors block the nucleic acid synthesis of the human immunodeficiency virus. d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Answer:
d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Explanation:
Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.

What is the molecule called that all living things use for immediate
useable energy?
ATP, Sugar,fat, All of these
Hello there!
I think ATP would be the answer in this instance. See, ATP is the pure form of energy that cells prefer to use. Sugars and fats are good for energy, too - but sugars and fats must be converted into energy before use. So ATP is the only energy source listed that doesn't need to be metabolized before the cell can use the energy.
