Wild orchids and mycorrhizae demonstrate mutualism, with the fungi providing nutrients for seed germination and growth, while the orchids give sugars upon photosynthesis.
The interaction between wild orchids and native mycorrhizae in the soil is a form of mutualism. Orchids produce tiny seeds that lack sufficient nutrients to support their germination and initial growth and therefore depend on a symbiotic relationship with mycorrhizal fungi, usually Basidiomycetes, for essential nutrients and carbohydrates. The fungus receives sugars from the orchid once it can photosynthesize, creating a mutually beneficial relationship. This mutualistic interaction is crucial throughout an orchid's lifecycle.
Which could be a reason viruses are considered nonliving things? Viruses come from cells. Viruses produce cells. Viruses are made of DNA and proteins, but not cells. Viruses attack cells and are dangerous to them.
Answer: Option C
Explanation:
The reasons why the viruses are considered to be non living things are:
They contain DNA and proteins but they are not considered as cells this is because they do not perform any cellular machinery as they they do not have organelles.
They do need host to survive they cannot live independently in nature. They do not grow in size and cannot keep them in steady state.
They cannot perform metabolic reactions and cannot generate energy for the life processes.

Which of the following is an example of a non-falsifiable hypothesis? A. There is a teacup orbiting the Milky Way galaxy. B. There is no life on Mars. C. The human species started in Africa. D. Humans cannot live without the amino acid methionine
The non-falsifiable hypothesis listed above is A. There is a teacup orbiting the Milky Way galaxy.
A non-falsifiable hypothesis is one that cannot be proven to be either right or wrong and there are two main reasons for this:
The hypothesis is based on a subjective premise. For instance, saying football is better than baseball. This is subjective because it depends on the person and so we cannot say for certain which is better or worse.Based on our current technological abilities, it is impossible to prove the hypothesis either wrong or right.We cannot prove that there is a teacup orbiting the Milky Way galaxy because we simply do not have the technological capacity to build a vessel that can go around the Milky Way to research this so it is a non-falsifiable hypothesis.
All the other options can be proven to either be right or wrong because:
we can go to Mars to check if there is any life, we can look at fossils to find out if humans came from Africa and,we can test to see if human cells survive without amino acid methionine.We cannot however, confirm if a teacup is orbiting the Milky Way so this is non-falsifiable.

why would two different species have similar features or behaviors?
A.similar DNA
B.similar mutations
C.similar environmental pressures
B. similar mutations
Final answer:
Species can have similar features or behaviors if they face similar environmental pressures leading to convergent evolution or if they have a common evolutionary history indicated by homologous structures. Analogous structures can also occur when species evolve independently to have similar adaptations.
Explanation:
Two different species may have similar features or behaviors due to the convergence of form in organisms that share similar environments, a concept known as convergent evolution. For example, the arctic fox and ptarmigan both have seasonal white phenotypes to blend with the snow and ice. This occurs not due to a common ancestry, but because of similar environmental pressures that offer advantages such as camouflage from predators.
Another reason for similarities might be due to homologous structures, which are features that are similar in form and genetic makeup and indicate a close evolutionary relationship. An example of homologous structures is the similarity in bone structure of bat and bird wings. However, when similarities occur between species that aren't closely related, due to adapting to similar environmental challenges rather than common ancestry, these are referred to as analogous structures or homoplasy. Insect wings vs. bird and bat wings are an example of such analogous structures.

Chicken pox is a virus that causes an itchy rash but typically does not have any major or lasting effects on an infected person. Before 1995, chicken pox parties were popular. In a chicken pox party, healthy children were brought around children who were sick with chicken pox so that they would be exposed to the virus and their immune system would learn to fight it. A vaccine for chicken pox was developed in 1995, and chicken pox parties are now rare. What best describes how vaccines have advanced science? Vaccines are more effective on ethnicities that are highly susceptible to a disease. Vaccines can determine which genes can cause disease. Vaccines can minimize lifestyle choices that allow for greater exposure to a disease. Vaccines allow for building immunity without harmful exposure because not all viruses are safe to be exposed to
Answer: yes
Explanation: well Chicken pox is a virus that causes an itchy rash but 1995
A vaccine for chicken pox was developed in 1995 Vaccines are more effective on ethnicities that are highly susceptible to a disease.
Which type of unconformity occurs when sedimentary rock overlies igneous rock?
Question 8 options:
disconformity
nonconformity
angular unconformity
conformity
Answer:
nonconformity
Explanation:
There are multiple types of unconformity that occur in nature, all of which are base on the relative position of the types of rocks. The nonconformity is one of the unconformities. This type of unconformity occurs when sedimentary rock overlies igneous or metamorphic rocks that existed there before the sedimentary rocks covered them. The nonconformity can be seen in lots of places around the world, but it is most common on places where there are water bodies like lakes, seas, oceans, ponds, marshes, or on places where there were water bodies of this type in the past.

What's one cause of the heat island effect? A. Pollution of groundwater B. Reduced rainfall in urban areas C. Higher albedo in urban areas D. Lower albedo in urban areas
Answer:
D. Lower albedo in urban areas
Explanation:
The heat island effect is caused by several factors, but one of the most important ones is the low albedo. This is particularly the case in the large urban areas. The large urban areas have low albedo, meaning that the solar radiation is accumulated in greater extent, and less of it is reflected back to the atmosphere. This results in an increase of the surface temperature, and the lowest parts of the atmosphere above it. The reason why this happens is that the urban areas are dominated by materials that have low reflection of the solar radiation, such as the concrete and asphalt. The concrete and asphalt are actually absorbing the solar radiation, so the their temperatures is increasing, and since they are the dominant materials, most of the area has rise in the temperatures. In practice this can easily be noticed by the people, as if the weather is warmer, in larger urban area it feels like we are in an oven, with heat surrounding us from all sides.
Answer:
D. Lower albedo in urban areas

What point in this body of water is most likely to have no plants growing
Answer:
Point D
Explanation:
Point D is the point that is most likely to not have any plants growing in it. The reason why this point of the body of water will not have any plants is because of the lack of light. This part of the body of water is dark, with no light penetrating to it. The plants need light to survive, as it is a vital element in the process of photosynthesis. If there isn't any light, the plants can not perform photosynthesis, thus they can not produce their own food, which in turn means that they will not exist in such a place.

Through which structure do wastes pass into the rectuin?
a. large intestine
b. villus
c. small intestine
d. duodenum
Answer:
A. Large intestine
Explanation:
This is because that's how the body works lol :)
Through large intestine waste is passed into the rectum.
Explanation:
In the digestive system the digested food material present in the stomach travels gradually from the duodenum to the small intestine where it splits into small molecules.
Whereas, absorption of those food material takes place through the small finger like structures present in the small intestine known as villi (singular-villus). After small intestine the food enters into large intestine where it reaches to the rectum to be excreted as waste.
What if biological profiles were created to identify individuals who were most likely to engage in criminal behavior? What would be the possible consequences of identifying believed criminals before they were actually criminal?
Answer:
the possible consequences of identifying believed criminals is by doing a back ground check
Creating biological profiles to identify potential criminals raises ethical issues and overlooks the social and environmental factors leading to crime. Sociologists reject biological explanations, focusing instead on socio-environmental factors for understanding crime patterns.
The student's question concerns the potential consequences of creating biological profiles to preemptively identify individuals who might be more likely to engage in criminal behavior. It is essential to recognize that sociologists generally oppose relying on individual biology or psychology to explain criminal behavior, as these theories fail to account for the social patterning of crime seen across different locations and demographics.
Biological profiles and identifying potential criminals based on genetic predisposition could lead to significant ethical and social issues, including discrimination and violations of individual privacy. Genetic markers cannot reveal the complex interplay of social, environmental, and individual factors that lead to criminal behavior. Moreover, profiling based on biological traits could reinforce existing prejudices and stereotypes associated with gender, race, ethnicity, social class, and more.
It's important to recognize that such biological theories once held sway but today are considered inadequate in explaining criminal behavior. The focus has shifted to socio-environmental factors that contribute to crime, which suggest that targeted interventions and inclusive social policies are more effective in reducing crime than profiling based on biology.
