of the following?
A. a simple brain with a nerve cord
B. pores in the skin for food to move in and a stomach in each
segment
C. longitudinal and circular muscles for movement
D. a heart of aortic arches and vessels along the body
An earthworm's body plan consists of all, EXCEPT pores in the skin for food to move in and a stomach in each segment. Thus, option "B" is correct.
What is an earthworm's body plan?The physique of the earthworm is segmented which appears like numerous tiny rings combined or merged collectively. The earthworm is made of around 100-150 segments. The segmented body portions deliver significant organizational purposes.
Segmentation can help the earthworm move. Each segment or piece has muscles and bristles named setae. The bristles or setae support the anchor and govern the worm when stirring over the soil. The bristles grasp a segment of the worm definitely into the ground while the other portion of the physique projects forward.
The earthworm uses parts to either contract or relaxes self-sufficiently to source the body to grow in one area or contract in other areas. The division supports the worm to be supple and sturdy in its drive. If each section stimulated collectively deprived of being self-governing, the earthworm would be stationary.
Thus, option "B" is correct.

explain why the metric system and si are important
Answer:
In simple terms, the metric system (which is the same as SI) is important because it's more coherent than the imperial system.
Explanation:
The metric system is far more used worldwide compared to the imperial system, where the imperial system is only officially used in three countries (U.S, Liberia, Myanmar).
There are multiple reasons why the metric system is important, but the most critical reason is that it's very easy to understand pertaining to calculations. The measurement system of SI is designed to make measurements/calculations easy to perform and understand. This is why scientists prefer using the metric system over imperial.
You can make some small comparisons:
--> Metric is consistently based on decimal numbers, while imperial uses different number systems (base 3, 8, 12, 14, 16, etc.,)
--> Metric works well with percentages, while imperial does not
--> Metric units are the same internationally, while some imperial units differ (i.e different pints, gallons, tons, etc.,)
There are fewer, simpler measurements in the metric system as compared to imperial where calculations start to get overcomplicated due to the amount of measurements/units in the system.
In layman's terms... metric is a boat on smooth water with perfect weather, while imperial is a boat on rough waters during a storm.

Answer:
number 3 is the central vacuole and its large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell
Explanation:
Answer:
3. Vacuole
Explanation:
Plant vacuole is a membrane (tonoplast) bound space which contains sap, water, excretory products and other materials (which are not useful for plants).
It occupies 90% of the volume of the plant cell. Tonoplast, in plants facilitates transport of ion into the vacuole (against the concentration gradient) which causes higher ionic concentration in vacuole than in the cytoplasm.Some other points:-
Amoeba have contractile vacuole for osmoregulation and excretory purposes. Some protists develop food vacuoles by engulfing food particles.From 2007 to 2010, the mink population stayed fairly consistent, but in 2010, the population dramatically decreased. Which of the following could describe what happened to the population of minks?
The mink population ran out of space to live so many died
A catastrophic event occurred like a disease or big natural disaster that quickly wiped out a large number of mink.
There were more voles for the mink to eat, so their population increased
The bears began to eat the mink in 2010 so the population of minks decreased.
The most likely event that led to a sudden decrease in the population of mink in 2010 would be a catastrophic event. The correct option would be B.
Decrease in populationA sudden and sharp decrease in the population of an organism can be caused by a host of factors. These include:
catastrophic events such as disease outbreaks, natural disasters, famine, etc. a sudden appearance of predators in the environmentIf the predator has always been in the environment with the population of the organism, this will not result in a sharp decline in the population. A population of predators suddenly joining the environment may be the only cause for a sharp decline in the population of the organism.

does anyone know how to do this ? You are a bio-researcher on the planet Tawniwani, and you have been given the task of identifying and classifying the native fauna. Use this dichotomous key to identifyTawniwanian creature t.
A dichotomous key is a classification tool used to identify organisms based on morphological or behavioral characteristics. Individual C is a Roundus tricurlus.
What is a dichotomous key?
A dichotomous key is a significantly useful tool to classify organisms.
If you have an organism -or part of it- and you need to taxonomically identify it, you use a dichotomous key.
The key provides an easy and fast way for identification by describing different morphological or behavioral traits, leading you to the correct taxonomic classification.
The term dichotomous refers to how information is provided.
You will always have two options per feature (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.
Once you choose one of the options according to your organism, the key leads you to the following description, and you will have to choose one of the options again.
You will repeat this until you reach the name of your organism.
The key describes only specific traits that are useful for differentiation.
In the exposed example, for instance, we need to know the name of the individual C.
Step 1The first description is about the head size. The key asks you if the individual has a small or a large head. It has a small head, so the key tells you to move to description 2.
1a. Has a small head--------------------------- go to 2
1b. Has a large head--------------------------- go to 3
Step 2The second description is about the body shape. The key asks you if your organism has a narrow or a rounded body. And this individual has a rounded body, so the key tells you to move to description 7.
2a. Has a narrow body ------------------------ go to 6
2b. Has a round body -------------------------- go to 7
Step 3The seventh description is about antennae. Does your individual have curly or straight antennae? It has curly antennae. You have reached your organism's name. It is a Roundus tricurlus.
7a. Has a curly anteanne ------------------------ Roundus tricurlus
7b. Has a straight antennae--------------------- go to 8
Individual C is a Roundus tricurlus.
