Answer:
The correct answer is - variables that they didn't control and not enough replicates
Explanation:
In this particular case, Pablo and Johanna using too many variables in their experiment or research, All the variables used, are not controlled and with time these variables can not be replicated again on experiment groups.
They did not select a particular age or weight of dogs, the diets are different and they feed dry kibble to only one dog. There are so many variables and for a better result experiment, all variables should be controlled only the independent variable is permitted to manipulate.

Explanation:
So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...
RR would show the dominant trait of white fur
Rr would show the dominant trait of white fur
rr would show the recessive trait of brown fur

How does artificial selection differ from natural selection? Choose all that apply.
O During artificial selection, the mating pairs are selected by humans, not the organisms.
O The outcomes of artificial selection are predictable.
O Artificial selection requires variety in a population.
O Artificial selection does not help a population adapt to its environment.
Answer:
All answers should be selected.
Explanation:
Artificial selection means humans select the mating pairs which makes the outcomes predictable. Variety is required because it is how humans can "customize" the traits of an organism. However, it does not help a population adapt to its environment because these traits are made for human satisfaction, not the survival of an organism.

Come up with five ethical guidelines for research. Write statements that reflect your own views of
what is right and wrong. If you really love animals, an example of one guideline might be "No
animals may be used in research of any kind." However, when coming up with these guidelines, be
thoughtful about what they really mean. Think of the information you read about earlier. Try to
phrase your guidelines in a way that would allow research that you think would be beneficial to
still be done. You may find that certain circumstances may cause you to rethink your own ethics!
Answer:
No
Explanation:

What is abiotic and biotic? Write examples of each.
The biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
Abiotic factors come in all types and can vary among different ecosystems. For example, abiotic factors found in aquatic systems may be things like water depth, pH, sunlight, turbidity (amount of water cloudiness), salinity (salt concentration), available nutrients (nitrogen, phosphorous, etc.), and dissolved oxygen (amount of oxygen dissolved in the water). Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight

What is metabolism?
Metabolism refers to the chemical processes that occur within a living organism in order to maintain life. These processes include the conversion of food into energy and the use of that energy to power the organism's growth, reproduction, and other functions.
Metabolism can be further divided into two main categories: catabolism and anabolism.
Catabolism is the process by which the body breaks down molecules to release energy. It includes the breakdown of complex molecules such as carbohydrates, fats, and proteins into simpler molecules that can be used by the body's cells for energy. This process produces waste products such as carbon dioxide and water which are eliminated from the body.
Anabolism is the process by which the body uses energy to build molecules. It includes the synthesis of complex molecules such as proteins, nucleic acids, and polysaccharides from simpler molecules. Anabolic reactions consume energy, rather than release it, and they require precursors and enzymes.

what are some non examples of negative feedback?
Answer: (EXAMPLES). Human body temperature - The hypothalamus of a human reacts to temperature fluctuations and responds accordingly. If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.
Human blood pressure - When blood pressure increases, signals are sent to the brain from the blood vessels. Signals are sent to the heart from the brain, and heart rate slows down, thus helping blood pressure to return to normal.
Human metabolism - When a human is hungry, metabolism slows down to conserve energy and allows the human to continue living with less food.
Regulation of blood sugar in humans - When blood sugar rises, insulin sends a signal to the liver, muscles, and other cells to store the excess glucose. Some is stored as body fat, and other glucose is stored as glycogen in the liver and muscles.
Production of human red blood cells (erythropoiesis) - A decrease in oxygen is detected by the kidneys and they secrete erythropoietin. This hormone stimulates the production of red blood cells.
Explanation: Since we all know, A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response
