what happens to cells that do not take up the recombinant plasmid
Explanation:
they are not transformed , and they die soon after they are still transfo4med because the nearby cells are transformed they change to a new cell with new characteristics. THEY ARE NOT TRANSFORMED AND THEIR CHARACTERISTICS ARE NIT ALTERED
Discuss which type of reproduction is the "best" strategy for continuing a species through time in a changing environment and justify your answer.
Answer:
Any sort of sexural reproduction.
Explanation:
Unlike asexual reproduction, sexual reproduction allows the species being produced to adapt the the changing environment around it to increase the chances of survival. For asexual reproduction, clones are made of the parent and, therefore, cannot withstand any extreme conditions that the parent species couldn't. For a changing environment, sexual is the best to allow the specimen and its offspring to change positively along with the environment.
List several functions of G protein-coupled receptors
Answer:
A novel GPCR role in regulating cell density sensing. Homeostasis modulation (e.g., water balance). Involved in growth and metastasis of some types of tumors. Used in the endocrine system for peptide and amino-acid derivative hormones that bind to GCPRs on the cell membrane of a target cell.

and manufacturing practices powered by human and animal laborers to practices
powered by fossil fuels. This historical shift is known as the Industrial Revolution. Which
of these is a likely result of the Industrial Revolution?
A. A decrease in consumption of fossil fuels
B. An increase in formation of new fossil fuels
C. A decrease in formation of new fossil fuels
D. An increase in consumption of fossil fuels

What needs to happen for natural selection to occur? Highlight all that apply.
A. Some of the traits will provide individuals an advantage over others.
B. Some variation occurs in the inherited traits.
C. A natural disaster.
D. Individuals with certain traits are more likely to have an increased number of offspring
Answer:
A
Explanation:
Natural selection occurs because those with more favorable traits survive while the others don't. If there are no favorable traits in a community then there is no natural selection.
What molecule carries chemical energy that cells use for their functions?
Answer:
Adenosine triphosphate (ATP)
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

In osmosis molecules move through a semi-permeable membrane from a high concentration to a low concentration. True or False
Answer:
False
Explanation:
Osmosis is the movement of water molecules through a selectively permeable membrane from high to low concentrations.
Diffusion is the process in which molecules move from an area of high concentration to low concentration.
The statement doesn't say that the molecules are water, so we put false. If it is wrong then tell the teacher that she has to include water molecules in there to be more detailed.
The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

birds evolved from theropod dinosaurs, but in real time they are mostly

Although the living reptiles birds are most closely related to are crocodilians (archosaurs), when it comes to their relation to dinosaurs, birds evolved from theropod dinosaurs. These theropods share over 100 traits with modern birds.

Answer: As vertebrate animals, birds are ultimately related to all the other vertebrate animals that live or ever have lived on earth. But you may be surprised to learn that the family of vertebrates to which modern birds are most closely related is the crocodiles , which evolved, like dinosaurs, from a population of archosaur reptiles during the late Triassic period.

Explain briefly HOW we have different cell types (blood, skin, muscles, nerves, etc.) *
Answer: Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense

Quail use feathers for thermoregulation, flight and camouflage. What type of adaptation are feathers?
A. Structural
B. Behavioral
C. Physiology
D. Feathers are not an adaptation
Answer:
structural
Explanation:
In addition to flight and body feathers, birds also have down feathers. Down feathers are soft and fluffy because they don't have barbules and barbicels (the structures that hook feather barbs together). Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.

What are the environmental and economical
uses of soil?
Answer:
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.

What property allows carbon to form a wide variety of molecules?
a. It is the fourth most abundant element in the universe.
O b. It has an average mass of 12 AMU.
O c. It's electron configuration.
.
O d. It's number of protons.
Answer:
O c. It's electron configuration.
Explanation:
Electronic configuration is the property that allows carbon to form a wide variety of molecules. It is fourth most abundant element in the universe after hydrogen, helium and oxygen. It has four electrons in its outermost shell due to which carbon forms four covalent bonds with other elements such as hydrogen, oxygen, and nitrogen. Carbon also has the ability to making rings.
