Lodgepole pine trees produce seeds in cones. The cones open after being exposed to high temperatures created by wildfires. How does this adaptation help the lodgepole pine survive?

A) It allows the lodgepole pine tree to make more seeds in cones that are hard to open.
B) It creates more wildfires for the lodgepole pine tree to reproduce.
C) It makes the seeds travel and grow in areas where there are no wildfires.
D) It helps the lodgepole pine tree to protect the seeds and to reproduce.

Answers

Answer:

D

Explanation:

A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.

Answer:

D

Explanation:

A It allows the lodgepole pine tree to make more seeds in cones that are hard to open. IS WRONG B) It creates more wildfires for the lodgepole pine tree to reproduce. IS WRONG C) It makes the seeds travel and grow in areas where there are no wildfires. DEFINITLY NOT so that leaves it with D  It helps the lodgepole pine tree to protect the seeds and to reproduce.

Answers

Answer:

Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.

Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

.Variation within a population is heritable. Populations experience competition for resources.

Explanation:

Variation exist among individual, and this makes individual unique. Variation in shape,size,color exist in an organism.

Traits or character can be inherited from parents which means it can be transfer from one person or individual to another.

Each organism posses different traits for survival, some traits are presents as to better help some organism adapt to their environment.

In at least 200 words explain how DNA replicates

Answers

Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

~i hope this helps :)

Answer:

QUESTION:

ANSWER:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, like the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains

Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a primer

After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases. In this way, the polymerase assembles a new DNA strand on top of the existing one

Which quality of lipids does it demonstrate?

inability to store energy
ability to form chains of nucleotides
inability to break down in water
ability to provide structural support

Answers

Answer:

I thinks its d but not sure

Explanation:

Lipids are macromolecules composed of fatty acids. The diagram represents the inability of the lipids to break in the water. Thus, option c is correct.

What are lipids?

Lipids are said to be polymers as they are large molecules made of the monomers of the fatty acid chains and glycerol bonded together by chemical bonds. They include oils, fats, steroids, waxes, hormones, phospholipids, etc.

They are energy storage molecules along with carbohydrates and act as messengers in the form of hormones. They store energy in fat cells (adipose) for a longer period of time. They make the component of the cell membrane, blood cells, and cholesterol.

They are soluble in an organic solvent but not in water as it is a non-polar compounds with hydrophobicity and hydrophilicity. They are insoluble and remain intact in the water molecule.

Therefore, option c. the lipids do not break in the water.

Craft a strong thesis that fully responds to the prompt. Write full body paragraphs (6-10 sentences) that contain direct quotes and commentary that develops and expands your argument about the rhetorical choices and message of the author.The following passage is excerpted from the 1990 newspaper article America Needs Its Nerds by Leonid Fridman. At the time of the articles publication, Fridman was a graduate student at Harvard University and a member of Harvards Society of Nerds and Geeks. Read the passage carefully. Write an essay that analyzes the rhetorical choices Fridman makes to develop his argument.In your response you should do the following:Respond to the prompt with a thesis that analyzes the writers rhetorical choices.Select and use evidence to support your line of reasoning.Explain how the evidence supports your line of reasoning.Demonstrate an understanding of the rhetorical situation.Use appropriate grammar and punctuation in communicating your argument.There is something very wrong with the system of values in a society that has only derogatory terms like nerd and geek for the intellectually curious and academically serious.A geek, according to Websters New World Dictionary, is a street performer who shocks the public by biting off heads of live chickens. It is a telling fact about our language and our culture that someone dedicated to pursuit of knowledge is compared to a freak biting the head off a live chicken.Even at a prestigious academic institution like Harvard, anti-intellectualism is rampant: Many students are ashamed to admit, even to their friends, how much they study. Although most students try to keep up their grades, there is a minority of undergraduates for whom pursuing knowledge is the top priority during their years at Harvard. Nerds are ostracized while athletes are idolized.The same thing happens in U.S. elementary and high schools. Children who prefer to read books rather than play football, prefer to build model airplanes rather than get wasted at parties with their classmates, become social outcasts. Ostracized for their intelligence and refusal to conform to societys anti-intellectual values, many are deprived of a chance to learn adequate social skills and acquire good communication tools.Enough is enough.Nerds and geeks must stop being ashamed of who they are. It is high time to face the persecutors who haunt the bright kid with thick glasses from kindergarten to the grave. For Americas sake, the anti-intellectual values that pervade our society must be fought.There are very few countries in the world where anti-intellectualism runs as high in popular culture as it does in the U.S. In most industrialized nations, not least of all our economic rivals in East Asia, a kid who studies hard is lauded and held up as an example to other students.In many parts of the world, university professorships are the most prestigious and materially rewarding positions.
