Answer:

As algas são organismos que anteriormente eram incluídos no Reino Plantae, porém atualmente pertencem ao Reino Protista, sendo a Ficologia (fico = algas; logia = estudo) o ramo da biologia que estuda esses seres: unicelular ou multicelular (filamentosas), eucariontes, fotossintetizantes e viventes em ambientes de água doce (rios, lagos ou superfícies úmidas) ou salgada (mares e oceanos).

Esses organismos autotróficos, dispostos na superfície oceânica (compondo o fitoplâncton), consomem o gás oxigênio dissolvido na água para a sua respiração e liberam através do processo fotossintético cerca de 70 a 90% do oxigênio contido na atmosfera. Recebendo, portanto, a denominação de pulmão do mundo, diferente do que muitos pensam que seja a Floresta Amazônica.

A reprodução assexuada pode ser tanto por divisão binária, isso nas unicelulares, onde a célula se divide ao meio; quanto por fragmentação, mecanismo de cisão de um segmento no talo nas algas multicelulares. Contudo, algumas espécies multicelulares reproduzem por zoosporia, utilizando-se de células flageladas que se desprendem do talo, locomovendo-se até um local favorável para o desenvolvimento.

How does climate differ from weather

But climate is the weather of a place averaged over a period of time, often 30 years." Hope I helped!

From which part of the pituitary are hypothalamic hormones such as antidiuretic hormone (adh) and oxytocin released?
tatyana61 [14]
<span>The correct answer is posterior pituitary.</span>

ADH (AntiDiuretic Hormone) or Vasopressin is a peptide hormone which is produced in the hypothalamus. ADH is released from vesicles inside the cells of posterior pituitary into the circulation. ADH is released as a response of hyperosmolality of extracellular fluid. It increases the reabsorption of water in kidneys and constricts the blood vessels.

Oxytocin is also peptide hormone produced by the hypothalamus and released by the posterior pituitary. It has a role in sexual reproduction.
