Answer:
Robber crabs have more in common with humans than sponges.
Explanation:
Robber crabs have more in common with humans than sponges because sponges don't have tissues. Crabs and humans have specialised tissue.
Answer:
The correct answer is "qualitative, discrete".
Explanation:
A qualitative or discrete trait is defined as a characteristic that have no intermediate features, and is often the result of genetic alleles at a single locus. For instance, if the form the seeds of pea could be either round or wrinkled, but not with intermediate forms. This is the case of the fly that has white or red eyes, but does not have pink eyes or other colors in between.
Semen creates a(n)<u>alkaline </u>environment for sperm to safely travel through both the male and female reproductive tracts.
In the field of biology, semen can be described as a white, slippery fluid that is released from the male reproductory organ. Semen is also referred to as the seminal fluid.
The semen of males carries the sperm cells which are required for the fertilization of the female egg. The conditions should be favorable for the process of fertilization to occur.
The natural atmosphere of the vagina of a female is acidic in nature. The sperms need a neutral environment for survival. Hence, the semen is produced alkaline in nature to prolong the lifetime of sperm cells. The alkalinity of the semen neutralizes the acidity of the vagina.

Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.
In general, the warm to hot summers and relatively mild winters of the Mediterranean and humid subtropical climates are similar. More people live in humid subtropical regions, which are occasionally invaded by chilly air in the winter.
Overall, this region's winter temperatures are typically 10 to 20 degrees Fahrenheit cooler than those in Mediterranean regions.
Whether or whether the summers are hot or warm in a region with a Mediterranean climate determines the subcategory. In comparison to the dry summer heat of the Mediterranean climate zones, the summers in the humid subtropical zone are equally warm or hot, but they typically have significantly more humidity, resulting in sultry weather that generally feels more uncomfortable.
What is humidity?
The amount of water vapor in the air is known as humidity. The gaseous form of water, known as water vapor, is typically undetectable to the eye. The presence of precipitation, dew, or fog is predicted by the humidity.
The temperature and pressure of the system of interest affect humidity. In comparison to warm air, cool air has a higher relative humidity when the same amount of water vapor is present. The dew point is another relevant variable. As the temperature rises, more water vapor is required until saturation is reached. A parcel of air will eventually approach saturation as its temperature drops, without adding or losing water mass. A parcel of air can include a wide range of water vapor concentrations.
