Hope this helped :)

This type of blood cell is not a type of white blood cell is C. 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.

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.

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.

Only 10 calories did the bird actually absorb when there is a total of 1000 calories were stored in a plant chamber.

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.

Answer:

the flat horizontal lines indicate phase change

Explanation:

As the substance changes phase from solid to liquid and liquid to gas, the temperature remains contant due to latent heat energy.

Energy is being used to break the intermolecular bonds during phase change, therefore there is no change in temperature.

The main difference between the independent and dependent variables in an experiment is that the dependent variable is what the investigator controls, and the independent variable is what happens as a result of this. Thus, the correct option is C.

A variable is any factor, trait, or any condition which can exist in differing amounts or types in the experimental setup. There are different types of variables which include independent variables, dependent variables, categorical and continuous variables.

The dependent and independent variables are the most important variables in an experiment. The main difference between these two variables is that the dependent variable is what the investigator controls while the independent variable is what happens as a result of this.

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.

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.

b) The nucleus

Explanation:

The DNA in the nucleus gives instructions which is used to create proteins. Hence, the option (b) is correct answer.

The instructions used to create proteins originate in the nucleus. Therefore, option B is correct.

According to genomics, a cell's membrane-enclosed organelle called a nucleus houses the chromosomes. Three main things are the nuclear envelope, nucleolus, and chromatin body.

The nucleus functions as the cell's control center and genetic information store by containing the genome. Only the final phase of gene expression (translation), which takes place in the cytoplasm, is associated with the cytoplasm. DNA replication, transcription, and RNA processing all occur within the nucleus.

The number of atoms that remains at the said time is 3.76 * 10^11 atoms of Cl-36 and 2.62 * 10^12 atoms of Ar-36.

The term half life is used to explain the time taken for only half the number of radioactive atoms to remain.

Given that;

No = 3 * 10^12 atoms

t1/2 = 3.01 8 10^5 years

t = 9.03 * 10^5 years

Thus;

k = 0.693/3.01 * 10^5

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.

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.

Therefore, it is well described above.
