How does the number of genes in human cells compare with the numbers in other species?
Answer:
While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always proportional to genome size (blue bars, in millions of base pairs). Note how many genes a fruit fly can squeeze out of its relatively small genome.
What is a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.Comparative genomics also provides a powerful tool for studying evolutionary changes among organisms, helping to identify genes that are conserved or common among species, as well as genes that give each organism its unique characteristics.While the number of genes in an organism's DNA varies from species to species, it is not always proportional to genome size.Learn more:

what is photosynthesis
Answer:
photosynthesis is the cycle of plants using sunlight water and carbon dioxide.
Answer:
Photosynthesis is the process in which carbon dioxide, sunlight, and water gets turned into energy (glucose) by plants, and the plant releases byproducts (oxygen) back into the air.
Explanation:
Inside the plant is a small organelle (a little body inside a cell dedicated to a certain job) called a chloroplast. When a plant is in sunlight, it gets absorbed into the chloroplast and converted into energy by the chloroplast. While the plant is absorbing sunlight, it is also taking in CO2 (Carbon Dioxide), H2O (Water) and minerals from the soil to help in the process to generate energy.

If the half-life of a radioactive atom is 3,500 years. How old is the substance if the parent-daughter ratio is 1:127?
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
Half-life of the radioactive atom (t1/2): 3,500 yearsParent-daughter ratio ([A]/[A]₀): 1:127 (1/127)Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
Show how artificial selection could be used to develop a new breed of wheat with higher fiber content
Answer:
get wheat that has the desired content (in this case high fiber content)
breed them
amongst the offsprings/ wheat produced, select the ones with highest fiber content
breed them
repeat this process for many generations
Explanation:
Artificial selection is a process of selective breeding where humans choose certain traits to breed for in plants or animals.
What would happen in case of wheat?In the case of wheat, we could use artificial selection to develop a new breed of wheat with higher fiber content by selecting individual plants with the desired traits and breeding them together over several generations.
Below are the steps:
Identify wheat plants with higher fiber content: The first step would be to identify individual wheat plants that have naturally higher fiber content. This could be done by analyzing the fiber content of different varieties of wheat and selecting those with the highest fiber content.
Crossbreed the selected plants: Once we have identified wheat plants with high fiber content, we can crossbreed them to create a new hybrid variety. This involves taking the pollen from one plant and fertilizing the flowers of another plant with it. The resulting seeds will have a mix of genetic traits from both parent plants.
Select the desired traits in the hybrid plants: After the hybrid plants have grown, we would need to evaluate them for their fiber content. We would select the plants with the highest fiber content and use them as parents for the next generation of plants.
Repeat this process for several generations: The process of selective breeding would be repeated over several generations, with each generation being evaluated for fiber content and only the plants with the highest fiber content being used for breeding. This would increase the likelihood of producing a new wheat variety with consistently high fiber content.
Test and refine the new wheat variety: Once a new wheat variety with higher fiber content has been produced, it would need to be tested for its nutritional value, taste, and other characteristics. If the new variety meets the desired criteria, it could be released for commercial production.
In summary, artificial selection can be used to develop a new breed of wheat with higher fiber content by selectively breeding individual plants with high fiber content and repeating the process over several generations until a new variety with consistently high fiber content is produced.

IN YOUR OWN WORDS I WILL GIVE BRAINYLIST WHOEVER ANSWERS THIS CORRECTLY!!!
Answer:
The wildlife habitat will be changed and poison the wild animals.
Explanation:
The resource consumption greatly affect biodiversity of different plants and animals on Earth because resources helps the organisms to survive. Organisms used resources such as food, space and water etc for growth and survival. If these resources are used up by humans so the biodiversity is negatively affected and the wildlife habitat is converted into agricultural and urban land. The biodiversity is also affected due to production of waste that cause pollution and poison wildlife.

What are the four ways that RNA differs from DNA?
Answer:
RNA is single standard while DNA is double standard
RNA contains the sugar ribose, while DNA contains deoxyribose.
RNA contains uracil, while DNA contains thymine.
RNA can leave the nucleus, while DNA cannot.
Explanation:
RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
What is the difference between RNA and DNA?DNA stands for deoxyribonucleic acid which is defined as a double-stranded molecule consisting of a long chain of nucleotides whereas RNA stands for ribonucleic acid which is defined as a single-stranded molecule consisting of a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating but RNA does not replicate on its own.
The base pairing is of DNA is as follows: GC (Guanine pairs with Cytosine) A-T (Adenine pairs with Thymine) while the base pairing of RNA is as follows: GC (Guanine pairs with Cytosine) A-U (Adenine pairs with Uracil). RNA has the sugar ribose while DNA has the sugar deoxyribose. DNA is located in the nucleus of a cell and in the mitochondria while the RNA is found in the cytoplasm, nucleus and in the ribosome.
Thus, RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.

Significado del acoplamiento entre CTE y FosOx, es de bioquimica si alguien me puede ayudar por favor
Answer:
La teoría quimiosmótica indica que la cadena de transporte de electrones (CTE) y el proceso de fosforilación oxidativa (FosOx) están acoplados por un gradiente de protones.
Explanation:
La teoría del acoplamiento quimiosmótico propuesta por Peter Dennis Mitchell permite entender cómo el ADP se fosforila a ATP en mitocondrias y cloroplastos. La energía que se libera durante la cadena del transporte de electrones es utilizada por la célula para crear un gradiente de protones a través de las membranas internas de mitocondrias y cloroplastos. Subsecuentemente, la energía potencial creada a partir de este proceso es liberada por el movimiento de protones a favor de un gradiente electroquímico. Finalmente, la energía potencial creada a partir del flujo de electrones es acoplada a la fosforilación oxidativa para sintetizar enlaces fosfato de alta energía en el ATP a partir de ADP y fosfato (Pi).

Surprisingly, whales have hind limbs (leg bones) that they do not use, but that are thought to be left over from an earlier ancestor of theirs. This is an example of which type of structures?
Answer:
Vestigial organs
Explanation:
Vestigial organs/ structures are those parts of the body that have become redundant, weakened, or useless to the body as a result of prolonged inactiveness.
According to Charles Darwin's theory of evolution, he explains that parts of the body that are not used quite often do not develop any further, and as generations of offspring come and go, such parts become useless to the organism. This is the law of use/misuse of parts.
This is what happened to the whales. Over the years, the whales must have discovered that the legs were useless to them as they spent most of their time in the water. This led to the degeneration of such body part over thousands of generations, leaving them with just a faint trace of the hind limbs which were observed
