If an acorn falls off a tree, is it living or non-living??
Answer: living
Acorns are still alive even off the tree and eventually grow into plants in the right conditions.
Answer:
Acorns are alive. Acorns live and breathe. Since they have no teeth and claws, acorns defend themselves with have chemicals called tannins. Because acorns decompose slowly, some gardeners compost them separately from other materials that break down more rapidly. Others grind them before composting them, as this speeds up decomposition.
therefore they are still living

1. Describe the first hypothesis that scientists have about blindness in the Mexican tetra. Be sure to discuss pleiotropy in your answer.\
2. One effect of the Hedgehog gene is to make cave tetras go blind. What is another effect it might have?
Answer:
these are odd questions....
Explanation:
1. they are curious about how they get blind
2. the quills
Answer:
1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."
2. Another effect it might have is to improve cave tetras' sense of smell.

C. When the arm extends (straightens), which muscle contracts?
Explanation:
When your biceps muscle in your upper arm contracts, it pulls your lower arm in towards your shoulder. However, when it relaxes, your biceps cannot push your arm back out. To do this, your triceps muscle, on the underside of your upper arm, contracts and straightens your arm out.
Answer:
When your biceps muscle in your higher arm contracts, it pulls your lower arm in to your shoulder. when it relaxes, your biceps cant push your arm back out. and straightens your arm out.

Examples of how humans negatively affect local ecosystems are
A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads
B. Planting trees and other plants to attract native species
C. Creating laws to prohibit fishing from local streams
D. Removing non-native species from the environment.
Answer:
A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.
Explanation:
Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).
Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.
Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.
This leaves A as the answer.
Hope that helps you!
Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories
Answer:
D. 367
Explanation:
If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.
What is food energy?Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.
The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
To find the total calories, multiply the given biomolecules grams with their calorie count.
= 42 × 4 + 7 × 9 + 34 × 4
= 168 + 63 + 136
= 367 calories
Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

how are the new strands of DNA lengthened
Explanation:
New strands of DNA are lengthened by adding new nucleotides at the replication fork.
These methods primarily involve DNA synthesis techniques, such as polymerase chain reaction (PCR) and DNA sequencing methods. However, it's important to note that scientific advancements may have occurred since my knowledge cutoff, and there could be new techniques or technologies available.
PCR is a widely used technique that allows for the amplification of specific DNA sequences. It involves a series of heating and cooling cycles, which enable the DNA to denature (separate into single strands) and then be replicated using a DNA polymerase enzyme. By repeating this process, multiple copies of the DNA sequence of interest can be generated.
DNA synthesis involves the chemical synthesis of custom DNA sequences in the laboratory. This process typically employs a method called phosphoramidite chemistry. It starts with a DNA template strand and adds nucleotides one by one, using chemical reactions to build the new DNA strand. This method allows for the controlled synthesis of long DNA strands with specific sequences.
Modern DNA sequencing technologies, such as next-generation sequencing (NGS), can indirectly contribute to DNA lengthening. During the sequencing process, DNA strands are often amplified and replicated to generate sufficient material for analysis. This amplification step can result in the lengthening of DNA strands.

Write a 200-word report on your research, using proper grammar, correct spelling, and appropriate punctuation. Make sure you include:
A definition of overgrazing
A discussion on the damage overgrazing can cause
The advantages and disadvantages of each type of grazing
A discussion on the type of grazing you select to use, which includes your justification of why you selected the grazing strategy
Answer:
answer is in explanation before
Explanation:
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. Overgrazing combined with overstocking has the most damaging outcomes to the world’s natural environment. The scarcity of water resources, water pollution, degeneration of coral reefs, and eutrophication are all connected to overgrazing. The chief polluting elements include farm chemicals and animal wastes.
Types of grazing systems 1. Types of grazing systems Grazing animals (such as cattle, sheep and goats) feed on the leaves and shoots of grass... 2. Zerograzing In this type of grazing system, the animals are not allowed to go out into the pastureto graze.
Overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
What is overgrazing?There are three types of grazing systems: continuous grazing, rotational grazing, and intensive grazing. Continuous grazing involves leaving livestock on a particular area of land throughout the year. Rotational grazing involves rotating livestock to different areas of land to prevent overgrazing. Intensive grazing involves keeping livestock in smaller paddocks and rotating them frequently.
Hence, overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
