How can a gene that contains introns be made shorter for genetic engineering purposes? What does it use and how does it use it?
Answer:
reverse transcriptase to reconstruct the gene from its mRNA
Explanation:
Genetic engineering may be defined as the process of using the recombinant DNA (rDNA) technology in order to alter the genetic makeup of the organism. It is also called as the genetic modifications. It uses the science of biotechnology to modify and manipulate the genes of an organism.
A gene containing introns can be made shorter and still remain functional for the genetic engineering purposes by using the reverse transcriptase for reconstructing the gene from the mRNA.
It uses the reverse transcriptase of the mRNA.
What part of Henry's cochlea may have functional hair cells?
The organ of Corti of Henry's cochlea may have functional hair cells, it is the structure that makes the hearing organs.
What is cochlea?Sound waves enter the ear from the outside environment and pass through the external auditory canal before they hit the eardrum and cause it to vibrate.
The incus collects sound vibrations from the malleus, also known as the "hammer," which connects to the eardrum, and sends them on to the stapes.
The stapes are a network that moves the oval window in and out. This motion is collected by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ, and small hair cells that make up the lining of the cochlea.
Therefore, the organ of the Corti part of Henry's cochlea may have functional hair cells.

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

What is a food web?A food web is a network of interrelated food chains that represents the movement of materials and energy within an ecosystem. In a food chain, the various arrows symbolize the various species that are being consumed by one another and so represent the flow of energy. Additionally, it shows that an animal can eat a variety of foods.
Food chains that are linked together form food webs. In a food chain, arrows point from the organism being eaten to the organism eating it.
The energy flow in a food web is depicted by arrows. Food webs display every form of eating in an environment.
Thus, the correct option is B. eats more than just frogs.

Although longitudinal waves can travel through all media types, what is the disadvantage of this type of wave transmission? Particles become too close together as they bump into each other making it more likely to hit other particles down the line. The waves travel in all directions which does not ensure that it will come into contact with particles down the line. The efficiency of the wave transmission is greatly diminished as the media becomes less dense. The oscillation of one set of particles has a huge impact on neighboring particles.
Answer:
The efficiency of the wave transmission is greatly diminished as the media becomes less dense.
Almost all the energy and associated biomass in Earth's ecosystems comes from the
Sun. Which of the following is NOT true regarding energy transfer through an
ecosystem?
A
Decomposers recycle the matter contained by the dead biomass and waste and
make it available for use by producers and other consumers.
Ninety percent (90%) of the available energy is transferred from one trophic level
to the next. About 10 percent (10%) is lost to the atmosphere as heat.
с
Ecosystems sustain themselves by continuously cycling matter through the
trophic levels and capturing energy from the Sun or Earth and transferring it up
the food chain.
D
Energy flows from the Sun or from rocks through the primary producers and the
successive levels of consumers.
Answer:
D . Energy flows from the Sun or from rocks through the primary producers and the successive levels of consumers.
Explanation:
Energy flows only through the sun not the rock because sun is the ultimate source of energy which can be used by the plants for making their own food in the form of glucose during the process of photosynthesis. This plant is then eaten by primary consumer known as herbivore. These primary consumer is eaten by secondary consumer is called carnivores. The tertiary consumer feeds on the secondary consumer and so on. In the end, decomposers feed on the dead bodies of animals and releases nutrients which can be used again by the plants for making food.

how do the kidneys and the bladder work together??
Answer:
From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.

Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn't occur?
Hello. You have not shown the model of meiosis to which the question refers, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
Crossing over is a genetic phenomenon that occurs when two sister chromatids are broken at some points and the pieces are exchanged between them. these exchanges cause the appearance of completely new gene sequences, which can completely affect the expression of stretches in the cells where the crossing over happened, since this cell will have a different gene sequence than the others.
As you may already know, chromosomes are formed by two filaments, called a chromatid. These filaments are united by the centromeros and the union of two filaments and a centromero is called sister chromatides.

Answer:
The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:
1) root pressure (osmosis)
2) capillary action (adhesion)
3) evapotranspiration (cohesion)
Explanation:
The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.

Insertion mutation I believe.
A codon chart can be used to read the genetic code. To utilize this chart, start by finding the first codon nucleotide, then the second, and finally the third. The chart will then show which codon codes for the amino acid. Because the genetic code is degenerate, there are several codons for each amino acid.
What role of genetic code in DNA sequence?The genetic code serves as the body's language for converting the DNA instructions from our genes into the constituent parts of life. It is typically discussed using the “codons” found in mRNA since mRNA is the messenger that transmits information from the DNA to the site of protein production.
Therefore, TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
