Answer:
insects
Explanation:
insects are usually attracted by very colorful flower and flowers with good scent and most of this flowers are usually pollinated by insects.
Insects are usually attracted to flowers with nectar because of the sweet juices produced at the nectar
Answer: Warm-Up:
Write down two places in the school where
you think there might be a lot of bacteria,
and write down two places in the school
where you think there will be very little
bacteria. Explain why you chose these
places.
Explanation:
There is a lot of bacteria in the restroom because it is they restroom of course and there is a lot of people who go in and out through out the day. Some people do not wash their hands after using the bathroom, also from other places. One of the most cleanest areas might be the science lab because they are always cleaning up everything and disinfecting.
<h3><u>Answer;</u></h3>
C.) The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
<h3><u>Explanation</u>;</h3>
- Molecular clocks are used to date origin of species. They are based on the observation that random mutations accumulate in genes at a fairly constant rate
.
- Once a mutation rate is determined it can be used to establish dates of divergence of species.
- Molecular clocks can be used in putting a series of evolutionary events into chronological order, by comparing sequences from different species to determine when they last shared a common ancestor, in effect drawing the family tree.
According to the research, the correct option is hydrophilic region. Within the plasma membrane, most transmembrane proteins will be comprised of hydrophilic regions.
<h3>What is the
plasma membrane?</h3>
It is the laminar structure that delimits the cell composed of two layers of lipids, which orient their hydrophilic polar heads (that is, they have an affinity for water) towards the inside of the cell, keeping their hydrophobic parts and includes phospholipids, proteins and glycolipids that shape the unit.
Membrane phospholipids spontaneously assemble into a bilayer, whose hydrophilic regions are placed on the surface where transmembrane proteins are located since most of this type of protein is hydrophilic and hydrophobic regions are distributed in the central region.
Therefore, we can conclude that according to the research, the correct option is hydrophilic region. Within the plasma membrane, most transmembrane proteins will be comprised of hydrophilic regions.
