How would plant populations be affected if the populations of decomposers,
such as earthworms, decreased dramatically?
O A. Plant populations would flourish because they would no longer be
preyed upon by earthworms.
O B. Plant populations would suffer because the soil would have fewer
available nutrients.
O C. Plant populations would be unaffected by changes in the
earthworm population.
D. Plant populations would flourish because they would not need to
compete with the worms for nutrients.
pleaseee helppppp
Answer: B. plant population would suffer because the soil would have fewer available nutrients.
Explanation:
Earthworms are called a farmer's best friend as they make the soil more fertile. When earthworms purify the soil it makes it easier for the plants to grow as the soil is mineral rich. Decrease in the population of earthworms would make it difficult for the plants to grow because of the less fertile soil.

During a new moon, why can't we see the moon from Earth???
pls explain this in ur own words!!
Answer:

Sedimentary rocks leads to the transformation of igneous rock into sedimentary rock by moving it has been exposing it to energy from sediments as uplift, upward, the Sun and subduction, downward, Earth's Interior.
What is the sedimentary rocks?Sedimentary rocks are near the surface so the only one that works for that is sedimentary rocks are formed with water too, it weathers away at the rocks to form little sediments and metamorphic rocks are in the earths interior and sedimentary are at the exterior, metamorphic rocks are formed through extreme heat and pressure meaning its near the earths interior.
Igneous rocks has been called the magmatic, are all rocks that are formed by the solidification of magma. However, igneous rocks are classified into two groups. First are the plutonic or intrusive igneous rocks that are the result of the solidification of magma within the lithosphere. Secondly, there are the volcanic or extrusive igneous rocks that are the result of the cooling of magma that occurs at the surface or a shallow depth.
Therefore, Sedimentary rocks leads to the transformation of igneous rock into sedimentary rock by moving it has been exposing it to energy from sediments as uplift, upward, the Sun and subduction, downward, Earth's Interior.

Answer:
Which best describes Earth's south magnetic pole?
D - Moving
The south magnetic pole is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed vertically upwards. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.
Best describes Earth's south magnetic pole D. Moving
What is the difference between the geographic North Pole and magnetic north pole?Geographic north (also called "true north") is the direction towards the fixed point we call the North Pole. Magnetic north is the direction towards the north magnetic pole, which is a wandering point where the Earth's magnetic field goes vertically down into the planet.

Question 8 (1 point)
The scientific method utilizes which of these 4 strategies?
A) Hypothesis, Descriptive, Analysis, Publication
B) Hypothesis, Design, Analysis, Appllication
C) Hypothesis, Design, Analysis, Publication
D) Hypothesis, Research, Analysis, Replication
Answer:
D) Hypothesis, Research, Analysis, Replication
Explanation:
The scientific method is a research method used to produce knowledge. It consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility (the capability of reproducing the experiment in any other place by any researcher) and refutability (susceptibility to be refused).
There are different steps to follow in a scientific method:
Definition and problem statement. The question for which there is not an answer yet.Hypothesis formulation. A hypothesis is a scientific conjecture, not verified that requires corroboration. Data collection and analysis. This step involves testing the observations.ResultsVerification of hypothesis. This step involves the deriving of the working hypothesis.Conclusions and Discussion.These steps also include previous knowledge about the study object. A question the investigator wants to answer. The goal, which is what the investigator wants to know. The hypothesis that the investigator makes in order to predict what is going to happen. The experiment is performed to answer the question. Conclusions where the hypothesis is rejected or accepted.
This scientific method needs to be replicable. Replication refers to the need of repeating a research study, under different situations, different subjects, and with different researchers, to determine the safety of the original findings and their possibility of generalizing them to other situations and participants.

Alcoholic fermentation
1. Forms fewer ATP molecules and cellular respiration
2. Uses oxygen and ATP molecules as reactants
3. occurs in the muscle cells of animals and humans
Answer:
A.
Explanation:
It converts sugars into cellular energy without requiring much oxygen, but it doesn't provide nearly as much energy as a result of the process not using oxygen.
Answer:
1. Forms fewer ATP molecules and cellular respiration
Explanation:
Alcohol fermentation is usually done by yeast as us humans lack the genetic information to do it (however we can do lactic acid fermentation in low Oxygen level which produce Lactic acid, which is what hurts after a day or two of heavy playing or workout)
Alcohol Fermentation only produces two ATP which is significantly lower than what cellular respiration makes (scientists predict there to be about 38 ATP from per cycle of respiration)
