Answer:
The water cycle is driven by the sun's energy. Water constantly changes state between solid, liquid and gaseous, this is due to solar energy and the force of gravity
Explanation:
Thanks to the effect of the energy of the Sun, water from the oceans and rivers, lakes, swamps, etc. It heats up and then evaporates. The sun is the one that governs the water cycle. The currents that rise in air transfer steam to the atmosphere, where it is at a lower temperature that causes the steam to condense and clouds form.
B. releases negative ions that create an electrical gradient that all sperm swim toward.
C. releases chemotaxic signals to attract sperm to its location.
D. propels itself toward seminal fluid by calcium-dependent kinesis.
Answer:
C. releases chemotaxic signals to attract sperm to its location.
Explanation:
An oocyte is female gametocyte which is involved in the reproduction. It is produced in ovary during the female gametogenesis. After ovulation, during luteal phase, egg is available to be fertilized by the sperm.
Sperm are attracted toward the eggs by the process of chemotaxis which is by following the gradient of chemical secreted by egg.
Thus, the oocytes in the female body control not only type of sperm they want ot attract, but also time at which they attract them.
Freshwater ecosystems, constituting a mere 1.8 percent of Earth's surface, are characterized by their biodiversity and the crucial ecosystem services they offer, including provision of drinking water, sanitation, and industrial uses. They house different zones due to varying abiotic factors like temperature and light penetration, with each zone inhabited by species adapted to these conditions. They are intrinsic to the well-being of terrestrial biomes, linked through various abiotic and biotic factors.
Freshwater ecosystems are of immense importance due to their rarity, diversity, and functionality. They encompass only 1.8 percent of the Earth's surface, including lakes, rivers, streams, and springs. These ecosystems are incredibly biodiverse, supporting a wide variety of species such as fish, amphibians, reptiles, insects, phytoplankton, fungi, and bacteria.
Humans are heavily reliant on these freshwater biomes as they provide indispensable ecosystem services. They supply fresh drinking water, assist in crop irrigation, provide sanitation facilities, recreation spaces, and serve various industrial purposes. Conservation of these freshwater ecosystems is crucial for the preservation of terrestrial biomes, as they are interlinked through abiotic and biotic factors.
Temperature, light penetration, and water movements are key abiotic factors influencing these ecosystems. The structural compositions of aquatic systems are largely shaped by density and temperature. Such factors delineate different zones within these systems, each housing organisms adapted to specific conditions.
