is the mass of wood charcoal and oxygen the same before and after the fire ?
Answers
Answer:
Here u go I even looked it up for u ;)
The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. ... For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant

Answers
Answer:
Negative adaptations will become more common in a population
Explanation:
that's the one that is NOT a principle
Negative adaptations will become more common in a population is NOT a principle of evolution.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.
when individuals in local populations spread between other local populations called as metapopulation.

Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a
Answers
Answer:
keystone species
Explanation:
The sea otter is an example of a keystone species in the scenario.
A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.
In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.

Where is the albedo effect the greatest?
a. Africa
b. Australia
c. Europe
d. Antarctica
Answers
A. Africa
Step-by-step explanation:
Here on Earth, the albedo effect has a significant impact on our climate. The lower the albedo, the more radiation from the Sun that gets absorbed by the planet, and temperatures will rise. If the albedo is higher, and the Earth is more reflective, more of the radiation is returned to space, and the planet cools.
An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answers
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N

Note:

Answer:
(i) Because they share the same genera, Vespula.
(ii) Because Morphologically, insects 1 and 2 are more alike than insect 3.
Explanation:
(i) Explain how the binomial names indicate that insects 1 and 2 are more closely related.
In taxonomy, many categories are used to aggregate organisms according to their evolutive relationship. These are Domain, Kindom, Clase, Order, Family, Genera, Species, Subspecies. All species might be recognized by their common name and their scientific name, which is more reliable. The binomial names of living beings indicate the scientific name by which the organisms can be recognized. A species scientific name is composed of two parts:
- Generic name or genera: correspond to many species that share common characteristics. In the example, Vespula is the genera
- Specific epithet: useful to identify each species in particular and differentiate organisms that are included in the same superior taxes. In the example, flavopilosa and rufa are the epithets that differentiate one species from the other.
According to this, we might assume that species 1 and 2 are more closely related because they share the same genera: Vespula. This suggests that they share more characteristics in common with each other than with Callicera.
(ii) Explain how the appearance of the three insects suggests that insects 1 and 2 are more closely related.
Morphologically, insects 1 and 2 are more alike than insect 3. Traits such as body shape, pigmentation pattern, antenna, wings, total body size, among others, are very similar in species 1 and 2. On contrary, species 3 is smaller, with a thinner antenna, different pigmentation patterns, different wings size and shape.
