6 0

Answer :It sets off warning signals in your brain and digestive system. This flips the on switch in a part of your brain called the vomiting center. It puts out chemicals that make you queasy. Chemo can harm your digestive tract, too, which could also lead to nausea.

Explanation:

Such side effects as nose bleeds, bleeding gums, blood in the urine or stool, and unusually heavy menstrual flow, may be experienced by the patient receiving chemotherapy. Nausea and vomiting occur when certain drugs stimulate an area of the brain called the chemoreceptor trigger zone.

Which objects allow humans to access groundwater? Check all that apply.

Masja [62]

<h2>Answer:</h2>

<u>The objects that allow humans to access ground water are:</u>

<u>A spring</u>
<u>a well drilled into an aquifer </u>
<u>a well drilled below the water table</u>

<h2>Explanation:</h2>

Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..

Novay_Z [31]

Answer:

d. Monosomy X is the only viable monosomy known to occur in humans.

Explanation:

Human have 22 pair of homologous chromosomoses and an extra pair of sex chromosomes. While in males the sex chromosomes are X and Y , females have two chromosomes X . Anyway, in normal conditions the total number of chromosomomes that humans have in their cells is 46 (23 pair of chromosomes).

Aneuploidy is a biological condition where an individual have an abnormal number of chromosomes in their cells. In humans for examples, this would be a human having more or less than 46 chromosomes.

The Turner syndrome also called monosomy X is an aneuploidy where one of the X chromosomes is missing in a female. Although under constant supervision, people with Turner syndrome have viable healthy lives. However this is the only monosomy that occur in humans that is compatible with life.

Which ecosystem has more biodiversity EXPLAIN!

Gekata [30.6K]

The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.

Hope this helps!
