Explanation:

Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.

Serous membranes line certain cavities within the anterior body cavity. <br> a. true <br> b. false
crimeas [40]

Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.

Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.

An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.

Explain the difference between selective breeding and genetic engineering in the development of food crops with desirable traits
Brums [2.3K]

Selective breeding is the traditional method for improving crops and livestock, such as increasing disease resistance or milk yield.

Genetic engineering is a faster way, which transplants genes for a desired characteristic into an organism. However, genetic engineering offers many potential benefits but carries the risk of unexpected harmful effects.

Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentca
postnew [5]

Answer:

can lead to natural selection

Explanation:

<h2></h2><h2>Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>

This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>

So overtime, the organism which is weaker  (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in  a way "<u>Nature selected"</u><u> </u>the better fit organism.
