Limited installation sites best describes a drawback in the scientists' plan because tidal energy is not present everywhere.
Describes a drawback in the scientists' plan?
The big disadvantage of tidal power is that there are limited installation sites for it. It is expensive as well as the turbines can adversely impact the surrounding ecosystem.
So we can conclude that limited installation sites best describes a drawback in the scientists' plan because tidal energy is not present everywhere.

What would you expect to happen to your Expiratory Reserve Volume when you are treading water in a lake
The Expiratory Reserve Volume will decrease when an individual is treading water in a lake.
What is Expiratory Reserve Volume?Expiratory Reserve Volume, ERV, is the additional volume of air which can be forcefully expired with maximum extra effort beyond the volume that can be expired in normal expiration.
ERV normally decreases with exercise.
Therefore, the Expiratory Reserve Volume will decrease when an individual is treading water in a lake.

The first three strata of the epidermis consists of ______ keratinocytes and the most superficial strata contain ______ keratinocytes.
The first three strata of the epidermis consists of living keratinocytes and the most superficial strata contain dead keratinocytes.
What is the role of the keratinocytes?Keratinocytes are the most common cell type in the epidermis, the outermost layer of the skin, accounting for over 90% of all cells. They begin in the epidermis's deepest layer, the stratum basale, and progress to the skin's last barrier layer, the stratum corneum.
The stratum basale (germinatum) is the innermost (deepest) layer of the epidermis, followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and the stratum corneum, which is the outermost layer.

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.What is the largest species of sea turtle in the world.

Determine which of the following statements is true about energy in ecosystems.
A. Primary producers lose 20% of the energy they absorb as urine and feces.
B. Consumers pass on 20% of the energy they get from a lower trophic level.
C. Primary consumers lose 60% of the energy they absorb from producers as urine and feces.
D. 10% of the energy Primary consumers absorb is lost as heat.
The community along with the biotic and abiotic factors makes the ecosystem. In the ecosystem, 10% of the energy primary consumers absorb is lost as heat. Thus, option D is correct.
What is an ecological pyramid?An ecological pyramid is the graphical presentation of the organism and the flow of energy at each trophic level. The trophic level constitutes the producers and the consumer.
The flow of energy follows the 10% energy rule where each trophic level loses and gains only a certain amount of heat. The heat is lost as excretory products in the environment.
The maximum amount of energy is gained by producers which passes to the primary consumers (10%), secondary consumers (1%), and the upper trophic level.
Therefore, option D. primary consumers absorb only 10% of energy.

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.

Energy in this ecosystem passes directly from the sun to.
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.

The process whereby cells begin to specialize, at about the eight-cell stage, is called: Please choose the correct answer from the following choices, and then select the submit answer button.
The process by which cells begin to specialize, at approximately the eight-cell stage, is called morula.
What happens in the morula stage?At this point, the embryo as a whole maintains the same size, that is, the newly formed daughter cells are smaller than the cell of origin. In the morula stage, the embryo differentiates into two cell groups located in the outer layer and the intern embryo.
Morula is the name given to the fourth stage of cell segmentation after fertilization of the egg.

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.
