Think back about your experience in this lab using a dichotomous key. What might make it hard for someone to use a dichotomous key? Make a list of possible reasons.
Answer: why it is hard to use dichotomous key in the lab are;
If the organisms you want to use it for are similar.
If you can't see the little characteristics posses by the organisms you are using it for.
If all the pictures does not reveal all the important features of the organisms.
It is very difficult to use it to determine the anatomical structure.
Explanation:
Dichotomous key is an important method that is use in biology to identify organisms by separating or dividing the organisms into two groups. It is a tool created by scientists to help them identify organisms or objects. Once the organisms are group into two, more information is revealed more individually.
Answer:
The person who commented before me was correct. They should get brainliest. Below is the same thing they wrote just in paragraph form.

THIS IS DUE TOMORROW - Why is it important to reduce your ecological footprint? What services do ecosystems provide for us/future generations?
Answer:
The ecological footprint (EF) estimates the biologically productive land and sea area needed to provide the renewable resources that a population consumes and to absorb the wastes it generates—using prevailing technology and resource-management practices—rather than trying to determine how many people a given land area
Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provisioning, regulating, and cultural services that directly affect people, and supporting services needed to maintain the other services.

Answer:
B
Explanation:
Answer:
C. Stay calm, watch the child's actions, and try to imagine what the child is feeling
Explanation:
Infants and toddlers are not able to communicate their feelings and emotions effectively. Caregivers need to observe the child's actions and body language to understand what the child is feeling. By staying calm and observant, caregivers can provide the right amount of support to help the child manage stress.

Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. Which of the following would make the best project?
Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
a video that shows a large river that has penguin populations on both sidesa video that shows penguin species that have different mating dancesa video that shows a penguin that is laying eggsa video that shows penguins in a tidal pool and an open oceanAnswer:
a video that shows penguin species that have different mating dances
The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.
The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.
In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.
Thus, the selected option is correct.
A video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.
What is Population?A population is defined as the complete set of individuals, whether that group includes a nation or a group of people with a common characteristic which is the pool of individuals from which a statistical sample is drawn for a study. .
It is described as a unit of biological community made up of a permanent group of an interbreeding individual of a species found in a space or geographic region at a particular time. Population are of three types of population pyramids created from age-sex distributions-- expansive, constrictive and stationary.
Thus, a video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. An example of evolution is how cell phones have changed over time.
HOPE IT HELPS : D
Explanation:
Evolution is a very important phenomenon, which is the change in the characteristics of species of organisms over the course of life for the purpose of better survival.
What is evolution?The term “evolution” is best described as the process of gradual and continuous change in the inherited characteristics of a species over many generations.
This change is driven by mechanisms such as natural selection, mutation, and genetic drift, which lead to variation in traits within a population over time.
The theory of evolution by natural selection is widely accepted among scientists as the best explanation for the diversity of life on Earth. In addition to its importance in understanding the development of life on Earth, the concept of evolution has far-reaching implications for many areas of study, including medicine, agriculture, and conservation biology.

A medical test indicates that a patient has a defective protein. This
condition is most likely due to a change in the directions coded in the:
number of phosphate molecules
sequence of subunits in DNA
number of nitrogen bases
sequence of sugar molecules
Answer:
number of nitrogen bases
Explanation:
The correct answer would be the number of nitrogen bases.
A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.
Mutation can occur in a variety of ways including:
1. Deletion of nucleotide base sequence in the DNA
2. Addition (insertion) of nucleotide base sequence in the DNA
3. Duplication of nucleotide sequence in the DNA
A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.
Hence, the correct option is number of nitrogen bases.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

Respond to the following based on your reading.
Colonization is largely blamed for bringing smallpox to the Americas. Why was this disease so devastating to Native Americans? Why can we now travel to different parts of the world and avoid contracting analogous diseases?
Answer:
Killing pathogens and then using them to provide the body with active immunity is called IMMUNIZATION . This is often done in young children.
When the immune system treats otherwise harmless substances, such as pollen, as if they were invaders, a/n ALLERGY can occur.
HIV is a virus that attacks WHITE BLOOD CELLS in the body, weakening the immune system.
Polio used to be fairly common and devastating. Thanks to widespread vaccination against polio, the disease is now considered ABSENT, no longer infecting nearly as many people as it once did.
Arthritis is an example of a/n AUTOIMMUNE DISORDER where part of a person’s body is identified as foreign and attacked by the person’s immune system.
Immunization helps involves the injection of dead pathogens into the bloodstream. This helps in the release of antibodies which helps in protecting the body against further attacks in the future.
Allergy happens as a result of the body system treating and attacking harmless substances.
This is because the ships which brought immigrants into the country had someone who had small pox on board which spread and many got infected and killed due to lack of vaccine and treatment.
Immunization helps people to travel without having to worry about diseases.
Answer:
vaccination
allergic reaction
t-cells

autoimmune disease
Europeans had been exposed to the virus that causes smallpox for many generations, allowing them to acquire immunity to the virus. Native Americans were not exposed to smallpox or similar viruses before, so they had no immunity to the virus. In modern times, before traveling abroad, a person often receives vaccinations or other medications to avoid contracting the diseases specific to that region of the world.
