If you mean higher boiling point than it is oil.
Answer:
B. The native species population would decrease because the nonnative species would be competing for food sources.
Explanation:
This question is describing the effect of invasive species. Invasive species are foreign species i.e. not native to a habitat or area, introduced into the area with the ability to outcompete and negatively affect the native species of that area.
Invasive species compete with the native species for food, space, mate etc., and tend to outgrow them. Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.
The food ingredient that is important for brain development is GLUCOSE.
Glucose is the only type of nutrient that the brain can use to carry out its biochemical activities. The brain usually use about 20% of the glucose content that is available in the blood. Absolute lack of glucose for brain use can cause one to go into coma.<span />
The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I
Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.
When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.
Answer:
"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>
Explanation:
Biological membranes are formed by two lipidic layers, proteins, and glucans.
Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.
Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.
