Answer:
pancreas
Explanation:
beta cells of the pancreas produce insulin
Answer:
oxygen
Explanation:
all engage in oxygenic photosythesis (top equation), which means that they require water and release oxygen
Answer:
Explanation:
Vertebrates are members of the kingdom Animalia and the phylum Chordata ((Figure)). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development. The deuterostomes, whose name translates as “second mouth,” consist of two major phyla: Echinodermata and Chordata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
Deuterostome phylogeny. All chordates are deuterostomes possessing a notochord at some stage of their life
Answer:
In both groups, sperm swim from antheridia to archegonia
Explanation:
Bryophytes are the plant group that does not have a vascular system. These plants do not produce seeds. Ferns and horsetails are seedless vascular plants. These plants have vascular tissues (xylem and phloem) to serve in the conduction of water, minerals, and sugars from the one plant part to the other. But these plants do not produce seeds and hence, are seedless vascular plants.
Both bryophytes and the seedless vascular plants depend on water for fertilization. These plants release their male gametes in water which in turn move towards the female gamete. Sperms, the male gametes of these plants swim in the water to reach the female gamete.
Antheridium is the male gametangium that serves as a site for the production of male gametes while archegonia are the female gametangia where the egg cell is produced.
Answer:: Jade's error occurs in the top-right square of the Punnett square. In this square, she identifies the phenotype as freckles, but to have freckles, the offspring must have at least one dominant allele. The offspring in this box are ff. Because there is no dominant allele present, the offspring will not have freckles.
Explanation: Did the assignment
