How could a scientist use the scientific method to learn more about the Cretaceous era?

Answers

First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.

After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.

After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.

After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".

At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.

The Cretaceous period was a prehistoric period that took place between about 140 and 60 million years ago. If a scientist wanted to use the scientific method to learn more about this time, he should implement the following steps:

Identify an unresolved issue or problem that you would like to address. Make a hypothesis that raises answers to these questions or problems. Carry out a series of investigations and experiments dedicated to verifying the hypotheses raised. Finally, having verified the hypotheses, propose a law or rule for the investigated questions.

Explanation:

The macromolecule which provides instructions for growth is nucleic acids. The correct answer is option B.

Macromolecules are large molecules made up of smaller subunits called monomers. There are four main types of macromolecules found in living organisms:

carbohydrateslipidsnucleic acidsproteins.

Nucleic acids are macromolecules that store and transmit genetic information. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are the two main types of nucleic acids. DNA contains the genetic instructions for the development and function of all living organisms, while RNA plays a key role in the process of protein synthesis. When cells divide and grow, they must replicate their DNA so that each new cell receives a complete set of genetic instructions.

Therefore, nucleic acids provide instructions for growth. Option B is the correct answer.

Systems encountered in nature at Earth's surface, such as a forest, are open systems in terms of energy and matter. Thus, option B is correct.

What is system in nature?

Systems encountered in nature at Earth's surface, such as a forest, are both open systems in terms of energy and matter. The outermost region of the atmosphere, based on composition, is the system.

It should be noted that the forest simply means the large area of land that's covered with trees and undergrowth. In this case, it should be noted that a forest is an open system in terms of energy and that a forest is an open system.

In terms of matter and resources, the Earth is essentially a closed system, because matter and resources are fixed.In terms of energy, the Earth is an open system, because there is a balanced transfer of energy.

Therefore, Systems encountered in nature at Earth's surface, such as a forest, are open systems in terms of energy and matter. Thus, option B is correct.

o the flooding of low-lying coastal areas
O the faster evaporation of water in the soil
O the decreased frequency of major storms

Answers

The branch of biology which deals with the study of oceanic water is called oceanology.

The correct answer is B.

The level of the ocean is rising every day due to increases in earth temperature due to excess emissions of carbon dioxide.

The rise of carbon dioxide will lead to increases in temperature that melt the ice. The melting of ice increases the sea level which is dangerous to the coastal or those areas that live near the ocean and might get sunk.

Hence, the correct answer is B  that is the flooding of low-lying coastal areas

Which of the following statements correctly state(s) the location or function of the cells in the epidermis and dermis? Select all that apply. Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis.

Answers

Answer:

Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.

Explanation:

Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.

Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.

Where does oxygen move from the respiratory system to the circulatory
system?
A. In the pulmonary artery
B. In the vena cava
C. In the alveoli
D. In the liver

Answers

Answer: Alveoli

Explanation: Alveoli of lungs are surrounded by extensive blood capillaries. The partial pressure of oxygen in the alveoli is higher than the blood entering the pulmonary capillaries, hence oxygen moves into the blood. Carbon dioxide in the lungs simultaneously diffuse out of the blood into the alveolar space.

Oxygen moves from the respiratory system to the circulatory system in the alveoli. The correct option is C.

What are alveoli?

Alveoli are tiny round sac-like structures present at the end of the bronchioles. Bronchioles are branch structures present in the lung, they are the main site of exchange of oxygen and carbon dioxide.

The transfer of oxygen from the respiratory system to the circulatory system is done by alveoli.

Red-green color blindness is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree. A pedigree is shown. Sam, Bella, Joshua, and Tim have filled-in shapes. Lisa and Monica have half-filled shapes. Which individuals in the pedigree are identified and labeled carriers for red-green color blindness? Lisa and Monica Sam, Tim, Bella, and Joshua Ben, Jenny, Mike, Carol, Katie, and Chris Ben and Lisa

Answers

Answer:

Lisa and Monica

Explanation:

The correct answer would be Lisa and Monica.

For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.

In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.

Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).
