Answer:
Urea is an organic nitrogen compound which is a waste product from the breakdown of proteins through nitrogen metabolism. It is excreted in dissolved form with the urine. It is used as a highly concentrated nitrogen fertilizer, and for making skin cosmetics.
Urea is found naturally in the urine of all mammals. When the body breaks down amino acids, its nitrogen is converted to the toxic substance ammonia, which in turn is converted to urea in the urea cycle. The amino acids are derived from degraded proteins.

Describe the relationship among cells,tissues,organs,and organ systems in the human body .HELP
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
Explanation:
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems.
Explanation:
The cell is a fundamental component of all organisms. A group of cells that have the same structure and function make up a tissue. There are four types of tissues in our body: muscular, connective, nerve, and epithelial. Several types of tissue connect into an organ. The organs collectivley make an organ system. The 12 systems in the body are nervous, digestive, cardiovascular, muscular, skeletal, endocrine, urinary, immune, integumentary, respiratory, excretory, and reproductive.

The following genotypes of two independently assorting autosomal genes determine coat color in rats:
A—B—(gray); A—bb (yellow); aaB—(black); aabb (cream)
A third gene pair on a separate autosome determines whether or not any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genotype results in albino rats regardless of the A and B alleles present. Determine the F1 phenotypic ratio of the following crosses:
a. AAbbCC x aaBBcc

Answer:
Energy and Work Energy is the capacity to do work or to produce heat. Internal energy is the sum of kinetic energy and the potential energydescribe matter and elements
Answer:
The term matter refers to something that consumes space and has mass, the "stuff" of which the universe is made, in other words. All matter consists of substances called atoms, which have different chemical and physical properties and can not be broken down by ordinary chemical reactions into other substances.

Answer:
1 and 4
Explanation:
Streams and small rivers flow together to create river systems. As the weather gets warmer, the snow and ice from the winter melts, which makes the water flow down the stream and into the larger river system. ... This can result in flooding due to more water draining in than being lost to evaporation.
Answer:
The flow of water in the streams increases.

How do changes in the environment affect an ecosystem ?
(5-7 sentences)
Answer:
There are many ways the environment changes an ecosystem. First, temperature can completely affect an ecosystem. This is important because if an ecosystem gets too warm or cold, the organisms living in there can die off since they aren't made to live in severe conditions. Secondly, weather can also affect an ecosystem by raining, wind, or natural disasters. This is important to an ecosystem because if it rains too much in an ecosystem that needs to stay dry, than the organisms could die. Finally, migration could also affect an ecosystem. Even though this seems odd, it surprisingly changes a whole ecosystem. If predators migrate to the ecosystem, than the organisms are at risk because they are prey and could be eaten. Clearly, an ecosystem can be affected by many things.

Answer:
brainliest plzzzzzzz
Explanation:
Carbon Dioxide is a chemical compound composed of one carbon and two oxygen atoms. It is often referred to by its formula CO2. It is present in the Earth's atmosphere at a low concentration and acts as a greenhouse gas. In its solid state, it is called dry ice.
A compound of carbon, hydrogen, and oxygen, the latter two usually in the proportions of water (CH2O)n. They are classified into mono-, di-, tri-, poly-, and heterosaccharides. Carbohydrates in food are an important and immediate source of energy for the body; 1 g of carbohydrate yields 4 calories.
