Why do most living thing not leave fossils behind
Answer:
Explanation:
I believe why most living things do not leave fossils behind is most likely because they are decomposed before the fossils are covered by grouts and a predator might've eat them. The fossils are created when a plant or animal dies in a liquid environment and is covered by dirt.
How does mutation lead to evolution?
Answer: Mutation plays an important role in evolution. ... Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

1.) What are some of the forms of evidence used to support the theory of Pangaea?
2.) Why aren't the planet's continents in the same formation as they may have once been during the time of Pangaea?
3.) Why is it important to study the theory of plate tectonics and continental drift?
Answer:
1) Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

40 POINTS AND BRAINLIEST PLS HELP After hearing about an oil spill, Natalia decides to investigate how oil may affect birds in aquatic ecosystems. She gets some bird feathers. She takes the mass of one, dips it in oil, then takes its mass again. The images show the bird's feather before and after being dipped in oil.
dry feather and feather-covered in oil
The table gives the mass of the feather before and after being dipped in oil.
Before Oil After Oil
Mass 1.1 g 4.5 g
Describe how the mass and the appearance of the feather changed because of the oil. Can Natalia clean off the feather using water? Predict what will happen if Natalia dips feathers covered in oil in either cold water or in hot water.
Answer:
the increase in mass might make itself unable to fly due to the weight of the oil . the oil also exposes it's sensitive skin. they become extremely soggy when dipped in water. the water takes over the oil and restricts movement of its feather
Explanation:
pls giv me brainliest
When the feather is covered with oil, it causes an increase in the mass and makes them unable to fly. Yes, Natalia can clean off the feather using water. As she will dip the feather in water it can clean the feather but also remove the natural waterproofing.
What is an oil spill?Accidentally pouring a large amount of oil onto the large water body surface is referred to as an oil spill.
As due to this, the bird feather will get into the oil and increases its mass and the appearance as it cause them to become mat and separate.
Natalia can clean the feather using water.
When she will put the feathers covered with oil in either cold or hot water will cause the removal of natural waterproofing of the feather.
Thus, these were the consequences according to the given scenario.

Scientists predict that ocean acidity could double (increase 100%) by 2100. What are the effects of ocean acidification on ocean plant and animal life give (2 examples) and on humans (give 2 examples)?
Thank you!
Answer:
Reduce amount of carbonate and dissolve calcium carbonate.
Explanation:
Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. ... Animals that produce calcium carbonate structures have to spend extra energy either repairing their damaged shells or thickening them to survive.
Ocean acidification will affect humans too! It will affect the food we eat since most of our shellfish requires calcium carbonate to form or to fortify their shells. Many of the fish we eat are also dependent on shelled animals for their food source, so the entire food chain is in jeopardy

In Canada the incident of sickle cell anemia has been increasing in the population. ----- contradicts the hypothesis.
Explanation:
In areas of Africa where malaria is widespread the number of sickle cell cases remains consistent generation after generation while on the other hand, In Canada the incident of sickle cell anemia are lower in the population because of environmental condition is not good for increase in malarial disease. In Africa, the environment is suitable for the mosquitoes that causes malaria so there is high increase of sickle cell anemia in the population.

In which of the following ways are bacteria similar to birds? (2 points)
(Ch. 27.4) Many people are allergic to substances in the environment, such as ragweed pollen, as well as foods, such as peanuts. Which of these statements BEST describes an allergic reaction to one of these substances? (1 point) A. The substance is similar or identical to human antigens, and so it triggers an immune system response. B. The substance invades the body and causes damage to tissues, which triggers an immune system response. C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response. D. The substance invades the body and triggers a response from the respiratory system or digestive system, but not the immune system.
Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.

Give three ways in which plants use the glucose made in photosynthesis.
Thanks
Answer: Energy source. Glucose can used as a substrate and broken down in plant cells by the process of respiration.
Plant energy storage. Thousands of glucose molecules can be linked together to form the complex carbohydrate starch.
Plant building material.
Explanation:
The three ways in which plants use the glucose made in photosynthesis are as follows:
Energy storage.Plant building material.Energy source.What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some algae synthesize their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.
Starch is stored in the plants that is a derivative of glucose. It can provide energy to the plants when environmental conditions are unfavorable to synthesize glucose.
Cellulose is another derivative of glucose which utilize in the building of plant cell walls to protect plants from the external environment.
Glucose directly provides energy to the plant cell for the fulfillment of metabolic activities like respiration, protein synthesis, cell division, etc.
Therefore, it is well described above.
