Answer:
Gastrovascular Cavity
Explanation:
Hydra is commonly found in freshwater ponds and ditches as solitary organisms, in underside of aquatic leaves and lily pads in cool,clean freshwater pools and streams. It has a *Cylindrical body shape*.
Hydra possesses an internal body cavity, the *Gastrovascular cavity *,lined by gastrodermis and has a single opening,the mouth,which serves as an anus.
The Gastrovascular cavity of Hydra is a site for *digestion and nutrient distribution*,and also serves as anus.
Answer:
Rate of cellular respiration is higher.
Explanation:
Photosynthesis is a process in which plants makes its food. This food is very significant for the plant and those who eats these plants. The factors which affect photosynthesis ,light intensity,carbon dioxide and temperature.
Light intensity: Without enough light plant cannot photosynthesize even there is plenty of carbon dioxide and temperature.
If there is no light the carbon dioxide uptake is below Zero(0) With no light there is no photosynthesis.So the rate of respiration higher than the photosynthesis.
If the light intensity increased the rate of photosynthesis will also be higher and more carbon dioxide uptake by the plant during photosynthesis
It was also found that an increase in testosterone during the PASP predicted subsequent willingness to choose competitive tasks (3, 28, 29). ... Aggression research in human studies has revealed an interesting property of testosterone dynamics, its rapid fluctuations provoking reactive aggression in response to stimuli.
Technically A and B, but A is more true, so it is the 'correct' answer.
The correct statement is liver cells possess transcriptional activators that are different from those of lens cells.
<h3>What are Transcriptional activators?</h3>
Transcriptional activators are specific protein sequences capable of activating gene expression.
These transcription factors (transcriptional activators) act to regulate gene expression in target cells.
Transcriptional activators are factors that enable the expression of certain genes in particular cell types.
