Which of the following aquatic ecosystems is likely to have both a littoral and benthic zone?
a Lake
b Open ocean
c Coral reef
d None of the above
Answer:
C. Coral reef
Explanation:
Coral reefs are both found in the littoral zone which is on the shore in a tidepool and in the benthic zone which is the low level of the ocean.
The aquatic ecosystems that is likely to have both a littoral and benthic zone is lake. The correct option is a.
What is littoral and benthic zone?The benthic zone, like the ocean, is the lake floor, made up of accumulated sunken organic matter.
The littoral zone is the area adjacent to the shore where light can easily penetrate and aquatic plants thrive. The pelagic zone encompasses a large body of water.
The Benthic Zone consists of organic sediments and soil at the bottom of a pond or lake. This zone will expand as the body of water ages. It is regarded as the digestive system of a pond or lake.
The littoral zone is a pond or lake's down-sloping shelf. This is the area that extends from the high-water mark to the shore and into the area where sunlight penetrates to the sediments at the bottom of a body of water.
Thus, the correct option is a.

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.

How much sperm does a man produce each day
Answer:
about 525 billion sperm cells
Explanation:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Answer:
1,500
uring spermatogenesis, your testicles make several million sperm per day — about 1,500 per second. By the end of a full sperm production cycle, you can regenerate up to 8 billion sperm. This may seem like overkill, but you release anywhere from 20 to 300 million sperm cells in a single milliliter of semen.

O C. Stationary
D. Moving
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.

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)
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.
