The correct answer is - 5:35 PM on Friday.
The low tides, as well as the high tides, occur two times in a lunar day, on exactly every half a lunar day passed. A lunar day is 24 hours and 50 minutes long, so every next low tide, or high tide, appears after 12 hours and 25 minutes after the previous one. In this situation we have a low tide that has appeared at 5:10 AM on Friday, so in order to calculate when the other low tide will appear we need to add 12 hours and 25 minutes on it, and that will gives the information that the next low tide will appear at 5:35 PM on Friday.
Answer:
The correct answer is - contains many genes for transcription factors that are present in cnidarians and bilaterian animals.
Explanation:
Placozoans are the simplest known metazoan organism known on earth and found in warm water and all over the globe. Placozoans are very small approximately 2 to 3 mm.
These are basal forms of marine free-living multicellular organisms. In the molecular studies, it is found that they have similar genes that are present in cnidarians and bilaterian animals for transcription factors.

Brief-ish answer:
"Fertilization in plants occurs when pollen grains are transported from anthers to stigma. When ripe pollen from an anther catches on the stigma of the same kind of flower, each pollen grain sends out a small thread-like tube."
Here's a fuller answer:
"</span>Fertilization occurs after pollination, when pollen grains land on the stigma of a flower of the same species. During this time, a series of events take place leading to the formation of seeds. A pollen grain on the stigma develops a tiny tube that runs down the style of the ovary. The pollen tube contains a male gamete which meets the female gamete in the ovule. Fertilization occurs when the two gametes combine and their chromosomes join. The resulting product is a normal complement of chromosomes, with some from either parent flower. The fertilized ovule forms a seed, which consists of a food reservoir and an embryo that later develops into a new plant. In gymnosperms (conifers) male gametes are enclosed in pollen grains and are transmitted by wind or insects to the female reproductive organs. Fertilization in angiosperms (flowering plants) occurs when insects or other animals transport the pollen to the female reproductive organ (pistil).<span>
</span><span>Fertilization is the fusion of gametes to launch the development of a new individual organism. In animals, the process entails the combination of ovum with a sperm, leading to the development of an embryo. Fertilization in plants occurs when haploid gametes meet to create a diploid zygote, which eventually forms an embryo.</span><span>"

Answer:
All responses are correct
Explanation:
1- This process of chemical extraction produces release of toxins that are toxic to other life forms
2- Sponges are critical organisms in the nutrient cycles
3- Sponges provide habitat for other species (fish, crustaceans, etc)
4- Sponges have the ability to regenerate when they are separated into pieces
The hydrologic cycle is another name for the water cycle.
