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
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.
Thus, the correct option is C. In the alveoli.

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.
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.
explain why traits that aren’t present in either parent could show up in the offspring or in future generations of the offspring.
It can show because it can be a recessive trait that can be showed up in ones genes. Recessive traits can be less present in parent parents but if both parents have similar recessive traits it can be able to show up in offspring and future offspring. Also it can show in offsprings because of earlier generations. The parents might not have these traits but grandparents are great grandparents might have the traits.
Which phrase best describes how scientists use the data they collect
The method used to collect data depends on the desired data.
The collection of data is the most essential step in the process of research. The value, authenticity, and evaluation of a research or project will most importantly depend on the qualitative as well as quantitative methods of data collection that we have used.
While collecting data, the scientist has to keep in mind the purpose of his/her research, the most appropriate and reliable methods for data collection as well as the advantages and limitations of a certain method. Hence, the data collection method for any type of data depends on our purpose behind that research and is designed according to it.

What is the purpose of an antibody? Group of answer choices to stick to an antigen, alerting your body of the presence of a foreign substance to send chemical messages to and from the brain and body to clot blood when the body has a cut our wound to carry oxygen to body cells and tissues
Answer: Antibodies are proteins that are found in the body on the surface of red blood cells and in the blood plasma ,they are very sensitive to foreign bodies and bad viruses and bacteria,when they notice the presence of anything that poses harm or a threat to the body system,they track it down and fight/destroy it.
Antibodies also play crucial role in hemostasis(stoppage of bleeding) in the sense that when the body is wounded or when someone gets a cut antibodies that are found in the plasma and some substances found in the platelets are released to play a role in sending signal to the blood clotting factors in the blood to be released to arrest the bleeding and prevent the person from bleeding out their entire blood.

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
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).

How could a scientist use the scientific method to learn more about the Cretaceous era?
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.Learn more in https://brainly.com/question/19496416
