Answer:
deuterostomes
Explanation:
During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.
Reproductive system and it's functions
A short period of time, after the onset of puberty. The first mature eggs starts to be released from the ovaries during menstruation. Menstruation may first occur during the start of puberty in women, it may start as early as 8 years old and can start late as 16 years old. Menstruation is the process wherein not fertilized eggs are being broken down and released from the body.
<span>Root hairs and all active transport mineral ions are used by plants to enable water absorption. The route of the movement of water inside the root would be illustrated through this sequence:Epidermis (outside layer of the roots) --> cortex (ground tissue layer just between the epidermis and the root's vascular tissue) --> endodermis(a layer outside the vascular tissue;responsible for mineral uptake of plants) --> stele( tissues combined inside the cortex) --> xylem (can be primary and secondary, both originates from provascular tissue and vascular cambium,maturing to its inside, respectively) --> phloem (can be primary and secondary too, both originates from provascular tissue and vascular cambium,maturing to its outside, respectively --> cambium(a meristem originating from an apical meristem, gives rise to secondary xylem and secondary phloem. </span>
The right answer is D.
Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.
The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).
