A sperm cell and an egg cell fuse to form which structure?
zygote
zygote = a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum
NOT FETUS
<span>In getting her plants to grow, the gardener should use the color blue for her colored translucent sheets. The reason for this is because it will be absorbed by the plants, causing them to get the light absorption that they so desperately need. Other colors, such as green, are absorbed into plants (as can be observed by their green colors), and thus they do not absorb the light through this color.</span>
Answer:
The statement that is true about red currents in the thermohaline circulation is that water in the red currents contain less salt (option A).
Explanation:
Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.
On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:
- <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
- <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>
The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.

Transpiration in plants requires adhesion of water molecules to cellulose, cohesion between water molecules, evaporation of water molecules and transport through tracheids. Cohesion between water molecules is as a result of hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule. Transpiration involves the release of water through the leaves in pores called stomata, this serves as a method of excretion of excess water and diffused gases.
Answer:
The soft palate reflexively opens the nasopharynx to allow the passage of food is called bolus is not true. During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx. Soft palate elevation prevents bolus regurgitation into the nasal cavity
Explanation:
When food is ingested into the mouth, the tongue carries the food to the post-canine region and rotates laterally, placing the food onto the occlusal surface of lower teeth for food processing.During food processing, food particles are reduced in size by mastication and softened by salivation until the food consistency is optimal for swallowing.during food processing, the tongue and soft palate both move cyclically in association with jaw movement, permitting open communication between the oral cavity and pharynx.When a portion of the food is suitable for swallowing, it is placed on the tongue surface and propelled back through the fauces to the oropharynx.. The area of tongue-palate contact gradually expands backward, squeezing the triturated food back along the palate to the oropharynx.Pharyngeal swallow is a rapid sequential activity, occurring within a second.During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx. Soft palate elevation prevents bolus regurgitation into the nasal cavity.
