Phoebe is taking samples from a lake to determine how the populations of aquatic life change during the summer. Each week for a month she takes samples from different areas of the lake. Over the course of a month, she finds the marine life listed in the chart below. What should Phoebe change about her methodology to better address her question?
Answers
Answer:
This question is incomplete
Explanation:
However, the main thing she needs to "change" in her methodology is to take samples from different lakes instead of taking samples from the same lake. This is because it is possible there are other factors affecting the population growth in that lake which might not be affected by the summer season.
Another thing Phoebe might want to look at is the possibility of conducting this experiment during other seasons (like winter or spring), to be sure what she is experiencing is actually as a result of the season.
Answer: Take samples from the same location each time.
*(IF)* this is in refrence to this chart (I will link it) then it would be (B) Take samples from the same location each time.
Explanation:
I took the test

In a population of deer in one year, six deer were born, five deer emigrated, three deer were killed by predators, and one deer immigrated. What can be determined from this information? Population growth is decreasing. Population growth is increasing. Population growth stays the same. Population reaches the carrying capacity.
Answers
Answer:
The correct answer is - Population growth is decreasing.
Explanation:
In the given question, the number of deers increases in the deer population is:
born: 6
Immigrated: 1
Total 7
7 deers are increased in the population this year. While the deers leave the population is:
Killed: 3
emigrated: 5
Total 8
So the population growth is: increase - decrease in population
= 7-8
= - 1
The value is negative that suggests that there is a decrease in population growth of the deer in a given year.
Answer:
The answer is A) Population growth is decreasing

1.) The manual is a gene.
2.) The manual is a chromosome.
3.) Each set of instructions is a protein
4.)Each structure is a gene.

Answer:
I'm guessing it's A
Explanation:
The correct answer is option 2. As the interlocking structure is a chromosome.
The chromosomes are the building blocks of the genetic code. a manual has instructions regarding how to build blocks and is also used to make models.
What are genetic instruction manuals?At the functional level genes, DNA is all instruction manuals that describe cells information. these genes are transferred during fertilization ad passed on to the offspring.

Worldwide, about twice as many people eat a plant-based diet as eat a meat-based diet. A plant-based diet requires fewer resources to produce. It takes 28 calories of fossil-fuel energy to produce 1 calorie of protein from meat. In contrast, it takes only 3.3 calories of fossil-fuel energy to produce 1 calorie of protein from grain. With the population continuing to increase, some people believe it may be necessary to give up meat-based diets to ensure that there are enough resources to produce food for all people.
Do you think that a plant-based or a meat-based diet is more nutritious, or are they both equally nutritious? Why does a plant-based diet require fewer resources to produce? Do you think people should eat less meat? Why or why not?
Answers
Answer:
I think that a plant diets and meat diets are equally nutritious. A plant-based diet requires fewer resources because if it was an animal the animal would need food and water every day, a plant needs water every couple days. I don't think people should eat less meat, because meat is good for you, meat helps you gain muscle mass, gives you stronger bones and hepls you gain protein.

What is the purpose of such a procedure?
to increase accuracy

to decrease bias
to decrease patient safety
Answer:
The correct answer is:
to decrease bias
Explanation:
This kind of experimental setup where a group of participant is given a non-medical treatment is known as a double-blinded placebo experiment. The principle of the use of a placebo is to reduce biases. Biases are influences that may affect the result of an experiment that does not arise from the effect of the treatment itself, but from some external factor. The researcher and the subject do not know which treatment is a 'sham', and which treatment is the real treatment, it helps to make approach neutral and rules out any effect of manipulations that may affect the result as a result of such knowledge.

Answers
Answer:
See the answer below
Explanation:
All living things have certain characteristics. The genetic code carries the directions for inheritance, and offspring usually resemble their parents. With asexual reproduction, offspring have the same traits as their parents. With sexual reproduction, offspring differ from their parents in some ways. Living organisms use energy and materials to grow, develop, and reproduce. These life processes involve a set of chemical reactions called metabolic reactions. Organisms have means of detecting a change in their environment and responding to this stimuli. Most organisms require that their internal environments remain in a fairly constant range, and so they maintain homeostasis. The ability of a group of organisms to change, or evolve, over time is necessary for survival in an ever-changing environment.
Sexual reproduction involves crossing over of genetic materials between non-homologous chromosomes during gamete formation unlike in asexual reproduction. Hence, offspring from sexual reproduction differ from their parents to an extent while those from asexual reproduction are clones of their parents genetically.
Life is generally sustained by chemical processes known as metabolic reactions. Substances are constantly being formed (anabolic) and being broken down (catabolic) within the body of living organisms.
Organisms respond to stimuli in their environment. They are equipped with means to detect changes and act accordingly. Most living organisms are required to maintain a relatively constant internal environment. The process of doing this is known as homeostasis. Organisms need to constantly evolve in order to keep up with ever-changing environment.
Which two activities provide the reactants for cellular respiration?
releasing air and exercising
breathing in air and exercising
releasing air and eating food
breathing in air and eating food
Answers
Answer:
Breathing in and eating food
Explanation:
To sum it up easily is the reactants for cellular resperation is glucose (sugar) and Oxygen. First we get oxygen from breathing (Obviously). Second we get glucose from eating foods.
The pharynx is where the air and food channels intersect. Air may enter the pharynx via breathing, which always occurs through the mouth or nose. The transition from an airway to a food channel occurs during swallowing. Thus, option D is correct.
What is the importance of cellular respiration in eating food?The oxygen you breathe is used by your body cells to convert the food you consume into energy. It is known as cellular respiration.
The cell uses oxygen during cellular respiration to metabolize sugar. The energy your body need is created when sugar is broken down.
That implies that you must use more effort to breathe in enough of it when eating. Your lungs and diaphragm are crammed by the food in your stomach, which makes it tougher for them to do their jobs.
Therefore, breathing in air and eating food activities provide the reactants for cellular respiration.

Answer:
This question is incomplete
Explanation:
However, it should be noted that the original cell theory is also referred to as the classical cell theory which has the following basic points
1) All living organisms are made up of cells.
2) Cells are the structural and functional units of life
3) All cells can only come from pre-existing cells or cells can only be cultured from pre-existing cells
However, the modern cell theory has some new points that the classical cell theory does not have. These include
1) Cells have and pass hereditary information during cellular division
2) All cells are made up of relatively the same amount of chemical composition and undertake the same metabolic activities.
These points should assist in answering the completed question
