Answer:
Volcanic gases. (Ans A)
Explanation:
Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.
In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.
Oogenesis and spermatogenesis both involve the chromosomal-reduction divisions of meiosis,which takes the gametes from the full complement of chromosomes to the Haploid number of chromosomes. Meiosis is the type of cell division that take place in the gamete cells, where diploid cells of the germ lines undergo cell division to yield haploid cells, normally the gametes are made through this process, that is, the ovum through Oogenesis, and the sperm through spermatogenesis. During fertilization the two combines to produce a diploid cell once again that undergoes continuous mitosis to form a zygote.
It is a unicellular organism. Yeast are a polyphyletic group of species within the kingdom fungi. They are predominantly unicellular.
<h2>
Answer:</h2>
The fossil is <u>A) </u><u>Index fossil</u>.
<h2>
Explanation:</h2>
Index fossils refer to the type of fossil which is used to characterize and distinguish geologic periods. Due to this function of index fossil, they are also called as guide fossil or indicator fossil. These fossils must have a short vertical range, wide geographic circulation, and quick developmental patterns.
Another term, Zone fossil is utilized when the fossil have every one of the characters expressed above with the exception of wide topographical dispersion, they are restricted to a zone and can't be utilized for relationships of stratas.
Engineering covers any field in which instruments or processes are created to go along with biomedical technology.
pharmaceutical covers any field dealing with medicine, the creation of medicine, and the provision of supplies for the medicine to be used covers any field that helps in analyzing DNA and identifying individuals from samples taken from crime scenes.
Medical equipment, devices, computer systems, and software are designed and developed by biomedical engineers by combining engineering concepts with medical sciences. The majority of biomedical engineers work in manufacturing, colleges, hospitals, and research facilities for businesses, institutes of higher learning, and healthcare organizations.
The pharmaceutical industry develops, manufactures, and distributes pharmaceutical pharmaceuticals for usage as medications to be given to patients in an effort to treat, immunize, or relieve their symptoms. Pharmaceutical firms may sell both brand-name and generic drugs as well as medical equipment.
