State how a deep current forms

Answer:

The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.

Explanation:

Answer:A

Explanation:

Answer:Epididymis->vas deferense->seminal vesicles->prostate gland->urethra

Answer:

sperm travels through the vas deferens, up the spermatic cord into the pelvic cavity, behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra

Explanation:

As succession proceeds in an ecosystem, there is an increase in population density. This is accompanied by the change in the species diversity as well. Thus, the correct option is B.

What is Ecological succession?

Ecological succession is the process through which the mixture of species and habitat in an area changes over the period of time. Gradually, these communities of species replace one another until a climax community like a mature forest is reached in that ecosystem, or until a disturbance, like a fire, occurs in that region.

The succession of an ecosystem begins with a pioneer species such as the lichens, some fungi species. Species such as the lichen begins to secrete acids which begin to break the barren land into a number of small particles. The small particles mix with the lichen species remains and starts the process of soil formation. On addition of the soil, more diverse plant species such as bryophytes and pteridophytes grow on the land. Later on, these plants are replaced by the most diverse angiosperm species. In this way, the species diversity tends to increase as a result of ecological succession.

Therefore, the correct option is B.

Answer: B.

Explanation: Ecological succession, quite literally, is the change in the species of an area/ecosystem that had earlier been completely wiped out. Wildfires are a prime example of that.
