The other members o the groups help them to survive by taking care of the pups.If it want for them maybe they would die.So the social or connection they have with them will help them to connect with them when they grow
The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.
Answer:
1. Bryofita
2. vascular plants
3. Seed vascular plants (gymnosperms)
4. Angiosperms
Explanation:
1. Bryofita
Around 475 million years ago, the origin of plants was thought to originate from aquatic ancestors (green algae). Adaptation to terrestrial life is proven by the presence of sporopolenin and layered gametangia that protect gametes and embryos. This adaptation occurs in bryophytes which are the first terrestrial plants. Bryofita or mosses develop into various vanations in their group. Most briolites do not have vascular tissue (water from the environment is diluted and absorbed by the SD, but some briophytes have water-carrying vessels.
2. Vascular plants
Around 400 million years ago, the evolution of plants was marked by the diversification of vascular plants (vascular plants). These early vascular plants are seedless plants, for example in the types of ferns seria into other groups of seedless plants.
3. Seed vascular plants (gymnosperms)
Plant evolution begins with the appearance of seeds, which are structures that protect the embryo from drought and the threat of environmental change. The emergence of these seed plants accelerated the expansion of plant colonization on land. Plant seeds consist of embryos and food reserves that are protected by a cover. Seed vascular plants appeared about 360 million years ago with the appearance of Gymnosperms. Gymnosperms consist of conifers with a variety of types. Conifers and ferns dominate life in the months between more than 200 million years.
4. Angiosperms
About 130 million years ago marked the emergence of flowering plants that have a somewhat reproductive structure
complicated where the seeds are protected by a room called the ovary.Because the seeds are protected in such a way that this group discusses closed seed plants or Angiosperms
