Answer:
by recombining DNA
Explanation:
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases. Each group of three bases (codon) corresponds to one of 20 different amino acids used to build the protein.

osmosis ........... just use a paraphrasing tool for the explanation below
Explanation:
Another method of movement across the membrane is osmosis. Osmosis is the movement of water from a region of higher concentration to one of lower concentration. Osmosis occurs across a membrane that is semipermeable. A semipermeable membrane lets only certain molecules pass through while keeping other molecules out.

Which of the following best describes a form of genetic drift in which the animal population is depleted, thereby reducing the population's genetic diversity?
A. bottleneck effect
B. disruptive selection
C. founder effect
D. gene flow
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population. So, the correct option is A.
What is the Bottleneck effect?The bottleneck effect occurs when population numbers are dramatically reduced as a result of natural disasters such as earthquakes, floods, and other natural disasters. The new population is composed of organisms that were able to survive the catastrophe whose allele frequency will be radically different from the original allele frequency.
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population.
Therefore, the correct option is A.

What is the positive aspect of GMO
The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
Today, those who directly see the most benefits from GMOs are farmers and agricultural companies. ... GMOs are also used to produce many medicines and vaccines that help treat or prevent diseases. Before GMOs, many common medicines had to be extracted from blood donors, animal parts, or even cadavers.

Explanation:
There are multiple positive aspects of GMO, but it has many drawbacks as well. Genetically modified foods can become more resistant to disease, pests, and even natural disasters(floods, drought, etc.)

A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides into cells of each group and allowed DNA replication to begin. When replication was halfway completed, she injected a drug into the cells to stop replication. She then examined the cells to determine the distribution of the newly-synthesized DNA. She found each cell of group A had many segments of new DNA in its nucleus, while each cell of group B had a single segment of new DNA in its cytoplasm.
What can the researcher conclude about the cells?
A.
Group A cells are prokaryotic because they must have many origins of replication.
B.
The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.
C.
Group B cells are eukaryotic because they must have a single origin of replication.
D.
The cells in group A are eukaryotic because they replicate their DNA in the cytoplasm or nucleus.

Why didn’t the greatest heart anatomist in history, Leonardo da Vinci, discover this simple technique that would prove that it was a pump?
Answer:
He found that the heart had four chambers and it connected the pulse in the wrist with the contraction of the left ventricle. He worked out that currents in the blood flow, created in the main aorta artery, help heart valves to close. And he suggested that arteries create a health risk if they fur up over a lifetime.
Explanation:
Leonardo da Vinci, being an anatomist, was limited by the technology and knowledge available during his time, which prevented him from discovering the simple technique that would prove the heart's pumping action.
Leonardo da Vinci lived during the Renaissance period (1452-1519), a time when scientific knowledge and understanding of anatomy were still in their early stages. While da Vinci made significant contributions to the field of anatomy, including detailed drawings and observations of the heart's structure, the concept of blood circulation.
The discovery of the heart's true function as a pump and the understanding of blood circulation came later in history, with the groundbreaking work of William Harvey in the 17th century. Harvey's detailed studies and experiments on the heart and blood vessels provided compelling evidence for the heart's role as a pump and the circulation of blood.

(d) A conservation group with a long-term goal of preserving species believes that all at-risk species will disappear whenever land inhabited by those species is developed. It has an opportunity to purchase land in an area about to be developed. The group has a choice of creating one large nature preserve with an area of 45 square kilometers and containing 70 at-risk species, or 5 small nature preserves, each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve. Which choice would you recommend and why
Answer:
each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve
Explanation:
I choose third choice of having each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve because allocation of separate preserve provides good space and less competition in that preserve. Less number of at risk species in a large surrounding area increase in population with higher rate due to availability of resources such as habitat, food and water in large amount as well as low competitors for these resources.

Which two processes allow water to enter the atmosphere?
evaporation and transpiration
precipitation and condensation
condensation and evaporation
transpiration and precipitation
Explanation:
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation.
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation. Thus, option A is correct.
What is transpiration?Transpiration has been known as the method by which water vapor would lost via the stomata of the plants. When the weather has very hot, the plant's loss of water vapor cools it down, and water from the stem and the roots moves upwards or has been started to pull into the leaves.
The direct impact of the transpiration has that it would regulates plant temperature and the provides water for the photosynthesis. It also transports the nutrients and the sugars through the plant's vascular tissues.Evaporation and the transpiration are the two processes that would allow water to enter the atmosphere.
Therefore, Evaporation has been known as a way of vaporization that use to occurs on the surface of the liquid as it has the transitions from the liquid phase to the gas phase.
