What are the two products produced by photosynthesis?

Answers

The two products are sugar and oxygen

Final answer:

Photosynthesis, a process used by plants, produces two main products, oxygen and sugars/carbohydrates such as glucose. Oxygen is generated as a waste product, while sugars represent energy-storing compounds vital for survival. This process uses sunlight, carbon dioxide, and water.

Explanation:

The two primary products produced by the biological process of photosynthesis are oxygen and sugar (or carbohydrates). During photosynthesis, plants use sunlight, water, and carbon dioxide to produce these products. Oxygen is generated as a waste product, while sugars or carbohydrates represent energy-storing compounds. These sugar molecules, like glucose, possess the energy that living organisms need to survive.

Here's a simplified representation of the process: 6CO2 + 6H2O + energy from sunlight = C6H12O6 + 6O2. In this equation, C6H12O6 represents glucose, a sugar, and 6O2 represents oxygen.

What stimulates the ribosome to move down one codon?

Answers

Answer:

The chain moves from the 5' - 3' direction caused by the use of GTP and several protein-enzyme complexes. As the polypeptide chain is produced the t-RNA move from site A to site P, and then are released into the cytoplasm. The polypeptide chain continues to grow, and is held to the ribosome by the t-RNA at the P site.

Explanation:

Final answer:

The ribosome moves down one codon during the translation process in protein synthesis through translocation, which is powered by GTP hydrolysis and the action of EF-G. This step is crucial for the ribosome to read mRNA and synthesize proteins accordingly.

Explanation:

What stimulates the ribosome to move down one codon is a process called translocation, which is an essential part of the translation phase of protein synthesis. During translocation, the ribosome moves along the mRNA molecule towards the 3' end by a distance of one codon (three nucleotide bases). This movement is facilitated by the hydrolysis of Guanosine triphosphate (GTP) and requires the action of elongation factor-G (EF-G), also known as translocase. As a result of this, the tRNA that was in the A site moves to the P site, carrying the growing polypeptide chain, and the deacylated tRNA in the P site moves to the E site and is then released into the cytosol.

At the end of the translation process, when a stop codon is reached, release factors will bind, causing the polypeptide to be released and the ribosomal subunits to disassociate. The ribosome can then be reassembled for another round of protein synthesis.

The Meselson-Stahl experiment provided the necessary evidence to discover the mechanism by which DNA replicates. They accomplished this discovery by first culturing DNA with the heavy 15N nitrogen isotope. They then allowed the "heavy" DNA to replicate with DNA grown in normal 14N nitrogen. The density of each generation of replicated DNA was recorded by marking its position in a test tube after centrifugation. The position of each generation was then compared to the positions of pure 15N DNA and pure 14N DNA. Suppose that the first generation after replication revealed two bands after being centrifuged: one at the pure 14N mark, and one at the pure 15N mark. Which method of replication would this observation support? (2 points) A. Dispersive replication B. Conservative replication C. Semiconservative replication D. Another generation would be needed in order to find a viable mechanism

Answers

Answer:

C. Semiconservative replication

Explanation:

Semiconservative replication is a mechanism of replication. Semiconservative model of replication states that in daughter cell, with new double-stranded DNA (cell after replication and mitosis) one strand is from the original template molecule while other is newly synthesized.

This is possible thanks to complementary pairing in DNA (each original strand of double-helix DNA is used as a template for the synthesis of the new strand).

Final answer:

The scenario presented in the question supports the Conservative replication model of DNA replication. In this model, the original DNA strand remains intact, and a completely new strand is synthesized. However, in the actual Meselson-Stahl experiment, they observed support for Semiconservative replication.

Explanation:

The observation described in the question would support the Conservative replication model of DNA replication. According to the Conservative replication model, the parental DNA strand remains intact, and an entirely new strand is synthesized. Thus, after one round of replication, you would observe one band of DNA at the 15N position (the original, 'heavy' parental molecule) and a separate band at the 14N position (the completely new molecule).

The Meselson-Stahl experiment is a classic in molecular biology, used to elucidate the mechanism by which DNA duplicates itself. The result described isn't what they observed, though, rather they saw a single band intermediate between 15N and 14N after the first replication, supporting the idea of Semiconservative replication: each new DNA molecule consists of one old strand and one new strand.

It is possible to produce an offspring from a zebra mating with a donkey. indeed, in the summer of 2012 in florence, italy, a male zebra climbed a zoo fence in order to mate with a female donkey. this resulted in the donkey giving birth to a live organism. however, this mating would not likely happen in the wild. which reproductive barrier would prevent this from occurring?

Answers

Final answer:

The mating of a zebra with a donkey is rare in the wild due to reproductive barriers such as character divergence and gametic barriers, which affect courtship, compatibility of reproductive structures, and potential genetic incompatibilities leading to issues like sterility.

Explanation:

It is possible for a zebra to mate with a donkey, and such mating can produce live offspring, known as a zonkey. However, this occurrence is rare in the wild due to various reproductive barriers. One such barrier that would prevent a zebra and donkey from mating in the wild is character divergence, which impacts courtship rituals, potentially leading to differences in female preferences or male behaviors that are incompatible between species.

Other prezygotic barriers include differences in reproductive anatomy or physiology, where the reproductive structures might not be compatible (for example in damselflies), or gametic barriers where the sperm and egg cells are unable to fuse successfully. Postzygotic mechanisms could also be at play, such as genetic incompatibilities that lead to offspring with reduced or no fertility, like mules, which are the sterile offspring of a female horse and a male donkey.

Embryonic stem cells have a larger differentiation potential than adult stem cells

Explanation:

This is because embryonic stem cells can develop in any other type of differentiated cell type in the body (pluripotent), while adult stem cells are limited in that way (multipotent or unipotent). So, we can say that embryonic stem cells are more flexibile.

Another advantage of the embryonic stem cells is that they are more easily grown in culture.

The genotype would be bb and the phenotype would be purple.

Explanation:

It wouldn't be red or blue because those genotypes are homozygous. Which means everything s the same. One purple wildcat offspring would have a purple father and mother. But since a blue and red wildcat are mating that makes the genotype heterozygous. Which would be purple.

Incomplete dominance occurs when both the alleles of the genes at a specific locus are characterized partly.

This type of dominance occurs when neither of the alleles is entirely recessive nor dominant.

The allele for the blue trait is purebred dominant (BB)

 

The allele for the red colour trait is purebred recessive (bb)

 

The allele for the purple colour is heterozygous (Bb)

There are two main divisions in the grassland biome: tropical grassland and savannas.

TRUE

FALSE

Answers

Answer:false there is 3

Explanation:

The correct answer is False.

Explanation

Biomes are places on earth that are characterized by the species (fauna and flora) that inhabit there, environmental factors such as climate, temperature, rainfall pattern, among others. One of the Earth's biomes is grasslands, which, as the name implies, are areas where grass predominates. Additionally, grasslands are classified into three groups: savanna grasslands, temperate grasslands, and steppes.

The first refers to grassland areas where warm temperatures predominate, for example, the savannas of Africa or Australia. Secondly, temperate grasslands, also called prairies, are characterized by extreme temperature changes and the absence of rainfall, due to this, trees and shrubs do not survive in these. Finally, there are the steppes, areas where the vegetation is similar to that of the meadow, with the difference that the environment is drier, these are characteristic of eastern Europe and Russia. So, the correct answer is False. there are three main divisions in the grassland biome: savannas, temperate grassland and steppes.

Different body cells can respond differently to the same peptide hormones because _____.
A. different target cells have different sets of genesB. the hormone is chemically altered in different ways as it travels through the circulatory systemC. the circulatory system regulates responses to hormones by routing the hormones to specific targetsD. a target cell's response is determined by the components of its signal transduction pathways

Answers

Answer:

D. a target cell's response is determined by the components of its signal transduction pathways

Explanation:

Signal transduction pathway is a set of steps from the ligand binding (e.g. hormone binds to its receptor) to the cell response. The chain reaction that occurs after the ligand binding can include mechanisms such as phosphorylation, dephosphorilation, activation of messengers, degradation etc which together can make a whole huge network.

The cell response at molecular level can include change in gene expression (changes in transcription and translation), protein changes (conformational, post-translational modifications, change in location).

Different body cells can respond differently to the same peptide hormones because a target cell's response is determined by the components of its signal transduction pathways. Hence, the correct option is D.

. Although a hormone may travel throughout the body, only cells with specific receptors for that hormone can bind to it and initiate a response. This interaction then triggers a chain of events within the cell, leading to its response. Factors such as the number of receptors present (which may increase or decrease through upregulation or downregulation), the sensitivity of the receptors, and the specific signal transduction components available within the cell, all play crucial roles in determining how a cell responds to a hormone. This cellular diversity ensures that hormones can have varied effects on different types of cells, facilitating a wide range of physiological processes.

Osteomalacia is the disease in which bones become abnormally soft, mainly due to a deficiency of calcium and phosphorus, usually related to a vitamin D deficiency, and can increase the risk of developing osteoporosis.

The disease in which the bones become abnormally soft due to a deficiency of calcium and phosphorus in the blood, necessary for bone mineralization, is known as osteomalacia. In adults, this condition is often caused by a vitamin D deficiency, leading to reduced bone mineral density and an increased risk of osteoporosis. While osteoporosis involves the bones becoming brittle, fragile, and thin, often resulting from a lack of calcium in the diet, osteomalacia specifically refers to the softening of the bones. Rickets is a similar condition that affects children and is also most commonly caused by a lack of vitamin D, but can also stem from deficiencies in phosphorous or calcium.
