During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sent to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario? A. Hormones act as signal molecules between all body systems. B. Exercise is important for the body to function properly. C. Nerves transmit and respond to every major system in the body. D. Increased heart rate and blood flow decrease oxygen supply.

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).

Which is a negative effect of rising ocean temperatures?
the drying out of fertile land and the formation of dust bowls
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

A plant stores 3000 Joules of energy into an apple. If a pig eats the apple, then a human eats the pig, how much of the apple’s energy does the human incorporate into their body? A. 3000 Joules B. 30 Joules C. 750 Joules D. 3 Joules
Answers
According to the 10% law of the ecosystem, human will have 30 Joules of energy out of 3000 joules from apple. Thus option B is correct.
What is the 10% law of the ecosystem?In the food chain, at each trophic level, 90% of the energy from food is used up in metabolism or released as heat while only 10% is transferred to the next trophic level.
So 10% of 3000 joules of energy from an apple will be transferred to the pig which is 300 joules and the pig will give 10% of 300 joules to the human which is 30 Joules. So option B is correct.

Apple maggots are a type of fly native to North America. Prior to the introduction of the apple tree to North America, apple maggots fed from and laid their eggs on hawthorn trees. After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees. Adult apple maggots will only mate on the type of tree on which they were born. What is the most likely consequence of the introduction of apple trees to apple maggots
Answers
Answer:
B
Explanation:
Populations of apple maggots that mate on different trees could become reproductively isolated and eventually speciate.
Answer:
The correct answer is option B
The population of maggots on the apple tree (apple maggot) that will mate on different trees could become reproductively isolated due to different habitat (ecological isolation).
Ecological isolation causes speciation by creating reproductive barriers between populations due to different habitats.The maggot populations will mate on different trees and will eventually speciate over a period of time.

describe how fertility drugs help women to become pregnant
Answers
Answer:
Fertility drugs contain FSH and LH, which stimulate eggs to mature in the ovary. Fertility treatments increase a woman's chance of becoming pregnant, although the treatment may not always work. On the other hand, because the treatment boosts the production of mature eggs, it increases the chance of twins or triplets.

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.

If a plant has a high concentration of minerals inside its root cells, but does not have enough energy for active transport, what could happen to the minerals?
Answers
Answer:
The minerals will not be move or transported to other part of the plants because active transport require energy.
Explanation:
Active transport is a process where molecules and ions are move against a concentration gradient by using energy.
This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.
If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.

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.

Some chefs sometimes wrap meat in papaya leaves and the meat is marinated for five hours before it is cooked. What is the purpose of wrapping with papaya leaves? (in biology terms)
Answers
Answer:
See the explanation below.
Explanation:
Marinades serve two different functions: as a tenderizer and flavor enhancer.
Depending on the cut and type of meat, it may need a little assistance to bring it to a palatable range of tenderness. Certain plant and fungi enzymes and acids can break down muscle and connective proteins in meats.
As far back as pre-Columbian Mexico, cooks found that wrapping meats in papaya leaves before cooking made for more tender results. The active enzyme in the papaya leaves is papain, now refined from papayas and commercially available. The connective tissue that comes in direct contact with the protein-digesting enzymes gets broken down. These tenderizing enzymes also reduce the capability of the meat to hold its juices, resulting in greater fluid loss and thus drier meat.
