Where do sperm go after leaving the epididymis?
OA. Ejaculatory duct
OB. Seminiferous tubules
C. Vas deferens
OD. Urethra
c is the right answer
Explanation:
hope it will helpful for you.
On leaving the epididymis, the sperm is expelled into the vas deference, thus the correct option is option C.
Where is the sperm stored?The sperm are stored in the epididymis. Upon ejaculation, the sperm leaves the epididymis and migrates to the vas deferens.
The vas deferens create a protective fluid that protects the sperm while it's out from the urethra. If sperm does make it into the vagina, there’s a chance that it will fertilize the female egg.
Epididymis is a long tube that functions to transport sperm from the testis to the vas deference. While traveling through the different parts of the epididymis the sperm gets mature and acquires the ability to swim. So epididymis plays an important role in the maturation and transport of sperm.

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:-

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.

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.
