Answer:

The question is unclear but I suppose we're to match the stage of photosynthesis with it's description below.

Light-dependent reactions- Sun's energy absorbed

Light-independent reactions- Sugars produced

Explanation:

Photosynthetic process involves two main stages viz: light dependent stage and light-independent stage. In the light dependent stage, light energy from the sun is trapped or absorbed by the Chlorophyll pigment of green leaves. The absorbed energy is used to split water in a process called PHOTOLYSIS OF WATER.

This process (photolysis) releases protons that build up in the thylakoid membrane to produce a proton pump that generates ATP. At the end of the light dependent reactions, ATP and NADPH molecules are produced.

In the light independent stage which occurs in the stroma of the CHLOROPLAST, the ATP and NADPH molecules produced in the light stage are used to power and reduce carbondioxide (CO2) to synthesize sugar (glucose).

Rainforests are dense and canopied trees rich in biodiversity. They are destroyed to plant the cash crops that grow quickly and have various uses. Thus, option D is correct.

Cash crops are plants that grow rapidly and have many uses that benefit the economy. They are planted mainly for selling purposes and to make a profit.

Cash crops like sugar cane, tomatoes, cotton, tea, coffee, etc. are planted to make a profit and earn money and differ from the agricultural crops as they are planted generally for sale purposes.

Therefore, cash crops are fast-growing crops.

Answer:

More carbon dioxide gas would be found in the atmosphere.

Explanation:

Photosynthetic organisms convert carbon dioxide in air to oxygen through photosynthesis, while other non-photosynthetic organisms only consume oxygen and release carbon dioxide through respiration, they do not undergo photosynthesis.

When the number of photosynthetic organisms on the earth decreased drastically, the carbon dioxide released from other non-photosynthetic organisms cannot be converted to oxygen, so carbon dioxide in air accumulates.

I think it's that they have two alleles for the gene

The statement that Mendel’s pea plants had either purple or white flowers means that the plants have two alleles for the gene.

Gregor Mendel is regarded as the Father of genetics due to his immense contribution to knowledge of genetic inheritance.

According to Gregor Mendel, a gene consists of two alleles, which individually encode different phenotypes of a particular trait.

In this question involving flower color gene, two alleles coding for purple (P) and white color (p) are present in the gene.

If photosynthetic organisms are decreasing on Earth there is no consumption of carbon dioxide, hence option 4 is correct.

The amount of oxygen in the atmosphere will likewise decrease as the number of photosynthetic species rises.

More carbon dioxide gas would be found in the atmosphere because forests, especially rainforests, create more oxygen. The development of oxygenic photosynthesis was the most significant metabolic advancement in Earth's history.

It liberated life from the finite supply of reductants drawn from geochemistry and allowed it to create energy and reduce power directly from sunshine and water.

Therefore a decrease in photosynthetic organisms increases the carbon dioxide gas in Earth’s atmosphere.

The immune response is usually triggered by the presence of the donor's own unique set of HLA proteins, which the recipient's immune system will identify as foreign.

To prevent infection, the immune system launches an attack against foreign invaders when it comes into contact with them. The immune system must be able to distinguish between our own healthy tissues and external invaders in order to avert an attack on our own cells and tissues (autoimmunity).

When the recipient's immune system assaults the donor graft and starts killing the transplanted tissue or organ, graft rejection takes place. The presence of the donor's own distinct collection of HLA proteins, which the recipient's immune system will recognize as alien, typically initiates an immunological response.

Histocompatibility refers to the degree of resemblance among the HLA genes of the donor and recipient; the more suitable the donor and recipient are genetical, the more accepting the recipient's immune system should be of the transplant. There will always be some degree of rejection, though, unless the donor and receiver are genetically identical (such as identical twins).

Therefore, the difference in HLA proteins results in graft rejection.

Answer:

It is because the electron microscope uses a shorter wavelength electron

Explanation:

In an electron microscope the sample is always bombarded with a stream of electrons. These electrons usually have shorter wavelengths.

The electrons interact with the sample component well, the result of which is transformed into an image which is always clearer and allows for greater magnification than the compound microscope as a result of the short wavelength electrons being used.

Answer:

Due to the shortened wavelength electron it causes a greater magnification than compund microscopes.

Answer:

Food (Sugars)

Explanation:

S. cerevisiae feeds on sugars for energy, in the process producing carbon dioxide and alcohol (this is fermentation in a nutshell). The carbon dioxide bubbles get trapped in the dough, creating the lift that makes the dough rise. The alcohol, meanwhile, evaporates when baking, transforming into gas that also contributes to the rise of the bread. The alcohol, along with acids produced during the fermentation process, impart that wonderful flavor and aroma associated with yeast-leavened breads.

One lives inland, while the other lives in the water.

Explanation:

Amblyrhynchus cristatus is a marine reptile that lives in the Galápagos Islands. This species attracted the attention of Darwin because it is a marine iguana that lives exclusively in the Galapagos and, interestingly, their close relatives inhabit in land, also in the Galápagos Islands. The marine and land iguanas from Galápagos form a phylogenetic clade that is characterized by high diversification levels, which are evidenced by conspicuous phenotypic differences. These species can hybridize with each other, but the offspring are infertile. Recently, it has been shown by using phylogeographic analysis that both species diverged 8-10 million years ago.

DNA and molecular evidences are the additional evidences to support Darwin's theory. The correct option is B.

According to Darwin's theory, all species of organisms emerge and develop through natural selection of slight, inherited variations that significantly raise the individual's capacity to compete, stay alive, and reproduce.

It is backed up by research from a wide range of scientific disciplines, as well as genetics, which shows that DNA from different species is similar.

Fossils, embryological studies, anatomical and morphological characteristics, and molecular biology are examples of evidence that support the theory of evolution by comparing DNA sequences.

Thus, the correct option is B.

Answer:What traits would orchids have if the MADS-box genes were not duplicated?

If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids?

Explanation: The example given by Plato

If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.

The DNA sequence of a gene is altered to generate a different result, which is known as a genetic mutation. The DNA sequence of that gene is permanently altered.

For humans to develop, which is the process of change over a number of generations, genetic variances are crucial. In one person, a spontaneous genetic mutation takes place.

The genetic mutation of that person is passed down through generations (hereditary) to their offspring. If the mutation increases a person's likelihood of survival or immunity to disease, it starts to be handed down through generations and disseminated throughout the community.

Therefore, If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.
