Does the high concentration of the morrison formation mean that more organisms lived here 150 mya compared to other other parts of the country
Answer:
Jurassic Fact: The Morrison Formation is named after the town of Morrison, Colorado.
Explanation:
The Morrison Formation is a rock unit from the Late Jurassic (155 million years ago-148 million years ago). It extends throughout the Western United States and often contains fossils of dinosaurs such as Camarasaurus, Diplodocus, Apatosaurus, Stegosaurus, Allosaurus, and others. Although the Morrison was deposited in a wide variety of environments, it is the river channels that are most likely to contain dinosaur bones. Quiet water lake and pond deposits are best for preservation of the small delicate skeletons of salamanders, frogs, lizards, and others. In order for a fossil to form, the body must be buried quickly before weather conditions and scavengers have a chance to scatter or otherwise destroy the bone. In the park you will also see "Rainbow Beds" of the Morrison, which are mostly crumbly grey and maroon mudstones. They are pretty to look at, but do not often contain dinosaur fossils.
The high concentration of the Morrison formation means that more organisms have lived here 150 mya compared to the other parts of the country. The given statement is true.
What is Morrison Formation?The Morrison Formation is famous for its dinosaur fossils, which have been collected for more than a century ago on this planet. This has began with a find near the town of Morrison, Colorado, in 1877. Through radiometric dating it was found that the Morrison Formation has taken place between 148 to 155 million years old on the planet.
The Morrison Formation is a rock unit from the Late Jurassic period. It extends throughout the regions of Western United States and contains the fossils of dinosaurs such as Camarasaurus, Diplodocus, Apatosaurus, Stegosaurus, Allosaurus, and others.

Spicules is the skeletal structures which occur in most sponges. They provide structural support, as well as determent against predators. Large spicules, visible to the bare eye are called as megascleres, while smaller, microscopic ones are called as microscleres. Spicule cell - reproduction is the incorrect option.
amoeboid cell - digestion
What is amoeboid cell?Amoeboid cells are the that have capacity to change shape due to the parts of the skeleton of the cell called cytoskeleton and plasma-gel which changes the consistency of the cell's cytoplasm. Amoeboid cells use a pseudopodia, or false foot, to move forward. They carry-out phagocytosis, which is to eat or ingest other cells.
collar cell - water current
The collar cells serve two functions. Firstly, they beat their flagella back and forth to force water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide. Second, the sticky collars of the collar cells pick up tiny bits of food brought in with the water.

A calorie is a measure of energy. Assume that there are 1000 calories of plants in a chamber. If grasshoppers (a plant eating insect) eat all of the plants and a bird eats all of the grasshoppers, how many calories did the bird actually absorb if only 10% of the energy is transferred between each level.
Only 10 calories did the bird actually absorb when there is a total of 1000 calories were stored in a plant chamber.
What is Calorie?A calorie may be defined as a unit of energy that we get from food products and burn during a physical workout.
According to the 10% law given by Lindeman, if a plant chamber consists of 1000 cal., the amount of energy transferred to herbivores is 10% of 1000 which is 100 calories.
Similarly, the 10% of 100 cal., gets transferred to the next trophic level which is carnivores or secondary consumers. The 10% of 100 is 10 calories.
Therefore, only 10 calories did the bird actually absorb when there is a total of 1000 calories were stored in a plant chamber.

The sentences describe situations that are the result of problems in the urine formation process. For the nephron shown below, match each situation to the step in the urine formation process where the problem lies.
The matching of each situation to the step in the urine formation process where the problem lies are as follows:
Step 1: Stella's urine contains protein due to inadequate filtration.Step 2: High toxin levels in the blood are due to Secretion. Step 3: Increased Metabolic wastes are due to inadequate Reabsorption. Step 4: The presence of vital Vitamins in urine is due to inadequate Reabsorption.Thus, Step 1 belongs to filtration, Step 2 belongs to secretion, and Steps 3 and 4 belong to reabsorption.
What is the important function of Nephron?The important function of the nephron may include the removal of all waste products through urine, secretion of numerous substances, excess water from the blood, etc.

a. split into smaller molecules
c. Changed its shape
b. combined with another molecule d. been diluted
Answer: B. combined with another molecule
Explanation:
i just took the test
Proteins are macromolecules composed of amino acid chains joined through peptide bonds. A denatured protein molecule has changed its shape. Thus, option c is correct.
What is protein denaturation?Protein denaturation is a process where the proteins under unfavorable conditions like temperature, chemicals, and pressure result in an alteration in their functions.
The basic structural organization of the proteins contains primary, secondary, and tertiary formation that gets altered at high temperatures resulting in the breaking of the covalent bonds and disruption of the amino acid chain.
This results in the protein breaking and forming the primary structure that leads to alteration of the shape and conformation. This change results in loss of the function and activity of the protein.
Therefore, option c. the denatured proteins result in alteration in shape.

ou are a molecule of nitrogen. Choose a starting point in the nitrogen cycle and describe the process you would go through to move through the entire cycle.
The initial point of the nitrogen cycle is fixation which is carried up by the bacteria. Some bacteria perform nitrification that makes the nitrogen usable for the plant species.
What do you mean by the Nitrogen cycle?The nitrogen cycle may be defined as the cyclic passage of nitrogen and its compounds throughout the environment and living organisms like microorganisms, plants, and animals.
The inorganic form of the nitrogen gets assimilated into the roots of the plants that absorb it by vascular tissues.
When this plant is eaten by animals, the nitrogen is transported into its body and synthesizes proteins. After the death of that animal, its excretion, and other waste the nitrogen is again returned to the soil which is then decomposed by bacterial species.

This type of blood cell is not a type of white blood cell is C. Platelet.
What is a platelet?Platelets are not a type of white blood cell. They are actually small, colorless cell fragments that are involved in the clotting process of blood. White blood cells, on the other hand, include various types such as lymphocytes, neutrophils, and macrophages, which play important roles in the immune response and defense against infections.
Platelets, also known as thrombocytes, are small cell fragments that circulate in the blood. They are formed in the bone marrow along with other blood cells. Platelets play a crucial role in hemostasis, which is the process of blood clotting to prevent excessive bleeding.
When there is an injury or damage to blood vessels, platelets are activated and aggregate at the site of injury. They form a plug to seal the damaged blood vessel and initiate the clotting cascade, which leads to the formation of a blood clot.
The correct answer is C. Platelet.
