Crossing over is a process which contributes to diversity in offspring of an organism. Which statement BEST explains this process?

Group of answer choices

A sister chromatid from one homologous pairs switches places with a sister chromatid from a different homologous pair.

Sister chromatids separate to form haploid cells during anaphase II

During metaphase II, sister chromatids of a homologous pair exchange genetic information.

Homologous chromosomes exchange genetic information during prophase I

The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.

The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.

In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.

This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.

The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.

Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.

Answer:

C.

Explanation:

thats just his first law of motion

Answer:

C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.

Explanation:

In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.

Answer:

Sexual reproduction.

Explanation:

Sexual type of reproduction used by the marine biologist in order to develop the new coral because variations in an organisms only be done with sexual reproduction. For producing new type of coral, the type of corals should be fused together in order to gain the desire characters in the organisms. So if the marine biologist want coral polyps with large stinging tentacles, sexual reproduction is the only way. From asexual reproduction, the offspring produce identical to parents so that's why we can't use asexual reproduction.

Answer:

Because oxygen is the mediator of active transport.

Explanation:

The greater the oxygen, the greater the active transport, since it requires ATP and this energy currency requires cellular respiration.

6. Ribosome

7. nucleus ⇒ cytoplasm

8. nucleotides

9. RNA polymerase

10. 2 and 1

11. messenger between the genetic information in DNA and the amino acid sequence of proteins in protein synthesis through central dogma.

12. wind up

Explanation:

After the transcription mRNA moves from the DNA to the ribosome out of the nucleus to perform the translation and produce amino acid chains. A Ribosome is the site of protein synthesis.

DNA or RNA both nucleic acids are made up of basic units known as nucleotides that join together to form ribonucleic and deoxyribonucleic acid.

RNA polymerase is the enzyme that binds with the DNA molecule and adds complementary sequences to build mRNA.

DNA molecules are double-stranded molecules that are attached to one another by the hydrogen bonds between the nitogenous basses whereas RNA molecules have only one strand in the structure.

mRNA plays the role of messenger between DNA molecule and ribosome molecule to carry out the genetic information coded in the DNA molecule to produce amino acids in the particular sequence to produce protein.

The formation of new DNA from the old DNA is called Replication and the formation of RNA from the DNA is said to be translation.

The central dogma of DNA defines the following:-

The answer to the following is as follows:-

6. The mRNA will release from the DNA and to the  CYTOPLASM.

7. For the game, use the directional keys/arrows to move the mRNA down and out of the nucleus. mRNA----> CYTOPLASM

8. Both DNA and RNA are made of building blocks called NUCLEOTIDE.

9. The enzyme that adds new nucleotides to build mRNA is called

RNA POLYMERASE

Each organelle within the cell has its own important job, similar to factory workers. Every organelle plays an important role and without one, the whole team loses function.

Cell is the basic unit of life. Cells unite together and forms tissue. Many tissue will unite and form organ. Organ will unite together to form a organ system.

The building elements known as cells make up all of these plants and animals, including worms in the soil, horseflies on farms, lemurs in the jungles, reeds in ponds, and trees in forests.

Similar to these instances, many live organisms are composed of numerous cells working together. However, certain forms of life, such as the various bacterial and protozoan species, are made up of simply one cell.

Most cells, whether they are solitary or a component of a multicellular organism, are too small to be seen without a light microscope.

Answer: Naked Seeds

Explanation:

Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.

The exposed seeds characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant.

Gymnosperms are a small category of plants that don't blossom and produce "exposed seeds."

Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.

Many gymnosperms bear their seeds in cones, which are known as "exposed seeds" because they are not visible until they are fully developed.

This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.

Therefore, option A is correct.

Explanation:

A forest ecosystem offers a variety of ecosystem services and functions. Prominent among the services offered include habitats to a variety of fauna, watershed protection, carbon sequestration, etc.

When the trees in a forest are removed by clear-cutting, some of the services and functions specific to the tree layers cease. The various habitats provided are destroyed and the organisms that live in these habitats disappear.

Hence, if a forest ecosystem is removed through clear-cutting, many species of organisms that lived in that ecosystem disappear. Their loss is due to habitat destruction.

Reducing the use of fossil fuels since they emit CO2 that reacts in water

CO2+H2O-->H2CO3

The following would most improve the health of coral reefs is reducing the use of fossil fuels.

One of the biggest threats to coral reefs is the so-called "coral bleaching", a process that leads to the death of hundreds of corals around the world. The phenomenon occurs when the temperature of the water increases, due to natural causes, such as El Niño, or caused by man, such as global warming.

Scientists have created a device that innovates the technique of transplanting corals from the recovery of fragments with tissue loss. The device works as a kind of cradle, where the fragments are kept until they recover and grow.
