An earthworm's body plan
consists of all, EXCEPT which
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.

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.

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.

Three cells are placed in three solutions of different concentrations. Determine the concentration of the solutions based on the predominant
movement of water molecules through the cells.
isotonic
hypertonic
hypotonic
Solution 2
Solution 1
Solution 3
The three types of solutions and concentrations can be classified as:
Solution 1: HypertonicSolution 2: HypotonicSolution 3: IsotonicWhat is the concentration of a solution?The concentration of a solution must be expressed in quantitative units. So-called concentration units are used, which are quantitative measures of the affinity of solute that dissolves. The relative amount of a substance is known as the concentration and is expressed in different units.
In this case we can classify these solutions as :
Hypertonic solution: has higher osmotic pressure and solute concentration.Hypotonic solution: has lower osmotic pressure and solute concentration. Isotonic solution: the solute concentration and osmotic pressure are equal, thus reaching equilibrium.See more about solution at brainly.com/question/7932885

4. Which of the following is a parasite?
(a) Mushroom
(b) Fungi
(c) stem
(c) Cuscuta
(d) haustoria
(d) Rhizobium
Answer:
C: Cuscuta is a parasite .
Explanation:
Mushrooms are a part of the fungi domain meaning that it is a decomposer. I'm not too sure whether it means stem body cells or a stem in a plant. Either way both are not parasites. Cuscuta is a plant that does not have chlorophyll (they can't carry out photosynthesis) and since this plant cannot make its own food, it feeds off a host plant that can make food. An organism that needs a host to survive is called a parasite. Haustoria is a part of some parasites however it itself is not one. And finally Rhizobium is a bacteria that converts Nitrogen into ammonia which helps plants.

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.
