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.

why does water take up more space than cold water? Your explanation should include the behavior of molecules in the water. 
HELP ASAP!!!!!!
Explanation:
the molecules in water is more tightly packed than ice, so water has greater density than ice as water freezes it expands. so ice has more volume ( it takes up more space, but has less density) than water.

Sodium has one electron in its outer energy level. According to the octet rule, _____.
Answer:
Referring to the octet rule, atoms attempt to get a noble gas electron configuration, which is eight valence electrons. Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Chlorine has seven valence electrons, so if it takes one it will have eight (an octet).
it wants to give up an electron?

A forest is cut down to plant a field of corn.How will this affect the bioversity of the area?
Answer:
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.

Which of the following statements best describes Community Supported Agriculture (CSA)?
A. a service club that provides volunteer labor to local farmers
B. special zoning laws permitting agriculture within residential neighborhoods
C. a local tax on the town or county scale that is contributed to local farmers
D. local farms that sell produce directly to subscribed consumers
Answer:
D
Explanation:
D. local farms that sell produce directly to subscribed consumers
/Community-supported agriculture (CSA) is a food production and distribution system that directly connects farmers and consumers. In short: people buy "shares" of a farm's harvest in advance and then receive a portion of the crops as they're harvested.

34 percent will be thymine since the amount of thymine corresponds with the amount of adenine.
Label each organism with its symmetry. Fill in asymmetry, radial, or bilateral.
1.) humans __________
2.) sponges ________
3.) starfish _______
4.) monkey ________
5.) baboons _______
6.) flatworms _______
7.) birds _______
8.) fishes ______
Answer:
1.) Humans: Bilateral symmetry
2.)sponges: asymmetry
3.) starfish: radial symmetry
4.) monkey: Bilateral symmetry
5.) baboons: Bilateral symmetry
6.) flatworms: Bilateral symmetry
7.) Birds: Bilateral symmetry
8.)fishes: Bilateral symmetry
Explanation:
The divisions and subdivisions of the kingdom Animalia is based on several important features which includes the body symmetry.
Body symmetry is defined as balanced division of body parts in an orderly manner. There are three main types of body symmetry these includes:
--> Asymmetry
--> Bilateral and
--> Radial symmetry
Asymmetrical body division involves animals that when divided, doesn't show any identical features. That is one side doesn't match the other side.. Atypical example is seen in phylum porifera, the sponges. They are simple aquatic invertebrates that lack specialised tissues.
BILATERAL SYMMETRY: This is where the body of animals can be cut along its axis in only one plane to give two identical halves, the right and the left side. The terms anterior, posterior, ventral, and dorsal are used to describe a bilateral symmetrical animal. The evolution of bilateral symmetry allow body parts to become specialised seen in most advanced animals.
RADIAL SYMMETRY: this involves animals where the body can be cut along its axis in any plane to give two identical halves. This is an ideal body symmetry for immobile organisms such as starfish and hydra.
Label each organism with its symmetry:

Each organism can be classified by three types of body plan symmetry:

What is the approximate temperature of the troposphere, mesosphere, and stratosphere.
Answer:
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.

What is an invasive species and how can it affect an ecosystem?
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.
