Describe how restriction enzymes and ligase enzymes are used to make the plasmids that are introduced to bacteria cells during transformation. Include the words sticky ends and complementary in your response.
Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., BamH), or blunt ends, where the resulting strands are of the same length (e.g., HaeIII). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.

To get a pure bred colored, you choose several colored flower plants, and let them self-fertilize,
then you plant and grow the seeds. Many of the self-fertilized plants have some colored and
some white flower offspring. You choose one of the plants from a family of all colored flower
plants, let it self-fertilize, then you plant and grow its seeds. All the plants you get have colored
flowers. Now what?
A. This colored flower
plant is pure-bred.
B. This isn't a pure-bred plant, you
need to start all over again.
C. The white flower plant (after it self-
fertilizes) will give pure-bred colored
flowers in the next generation.
Answer:
They are easy to grow & they have many traits that distinguish strains of pea ... Choose several of the colored flower plants, self-fertilize them, then plant and ...

Explanation:
The cell will ____________ in CORN SYRUP because _____________________________________________________.
Answer:
The cell will shrink because water can move in but proteins cannot move out.
Explanation:
Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink. This is also due to osmosis, but in the opposite direction. The corn syrup is mostly sugar.

What are similarities about Early earth and Modern earth
Answer:
Crust, mantle and core.
Water availability.
Volcanic eruptions.
Explanation:
The main similarities about Early earth and Modern earth is their layers of soil such as crust, mantle and core means that the both Early earth and Modern earth are made up of these three layers. At that time water is present in huge amount while on the other hand, in Modern earth water is also present in large amount as compared to land. Volcanic eruptions occurs in both early and Modern earth.
The respiratory system brings in _________ and the digestive system breaks down _____________ so that both substances are available to cells to make __________.
Answer:
Oxygen; food; adenosine triphosphate (ATP).
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells, so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).
All living organisms such as plants and animals require energy to function properly (life activities). The cell organelle where energy from nutrients are released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
This ultimately implies that, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Generally, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe (respiratory system) while glucose is absorbed by the body when they eat (digestive system).
Hence, the respiratory system brings in oxygen and the digestive system breaks down food so that both substances are available to cells to make adenosine triphosphate (ATP).

A. What are the two main types of seismic waves that are created during an
earthquake? p waves s waves surface waves
Explanation:
There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.

The theory of plate tectonics states that Earth's plates are always in motion. What geological evidence supports this statement?
Continental and oceanic plates differ in densities.
Selsmic activity occurs along plate boundaries.
Less dense plates always subduct beneath the more dense plates.
The sizes and shapes of continents remain the same over time.
Answer:
Seismic activity occur along plate boundaries.
Explanation:
Since the plates are constantly moving, the places where the plates meet, the boundaries, have seismic activity.
The geological evidence that supports this statement is that seismic activity occurs along plate boundaries. So, the correct option is B.
What are tectonic plates?Tectonic plates are huge slabs of rock that divide Earth's crust and move constantly to reshape the Earth's landscape. Such plates are also known as lithospheric plates and are generally composed of both continental and oceanic lithosphere.
Since the tectonic plates are constantly moving and the places where the plates meet and form the boundaries have seismic activity.
Therefore, the geological evidence that supports this statement is that seismic activity occurs along plate boundaries.

Explain the changes in the number of algae in the lake from February to June (3)
ANSWER
Answer:
Kindly check explanation
Explanation:
According to the graph given the number of algae is represented on the y axis while the month of the year is represented on the x - axis of the graph. The change in the number of algae from February is clearly depicted by an upward slope along the y-axis which means that there is continous increase in the Number of algae in the lake during this period, that is between February to June . It could also be seen that around June the optimal number of algaae is achieved as the number of algae tend to fall as we move beyond June.

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction: Fe + O2 → Fe2O3
Answer:
This question is incomplete, the complete part is as follows:
This equation is unbalanced. Which of the following is the correct balanced equation for this reaction?
A. 4Fe + 3O2 → 2Fe2O3
B. 3Fe + 4O2 → 2Fe2O3
C. 2Fe + 4O2 → 3Fe2O3
D. 3Fe + 3O2 → 4Fe2O3
E. 4Fe + 4O2 → 3Fe2O3
The answer is A. 4Fe + 3O2 → 2Fe2O3
Explanation:
This question involved a chemical reaction between iron element (Fe) and atmospheric oxygen (O2) to produce iron oxide. The equation is given as follows:
Fe + O2 → Fe2O3
However, this chemical equation is NOT balanced and not in accordance with the law of conservation of matter. To balance this equation, we have to make sure that the number of atoms of each element on the reactant side is equal to that on the product side. Hence, we use COEFFICIENTS. The balanced equation is given below;
4Fe + 3O2 → 2Fe2O3
