Answer:

For rainfed wheat grown in more arid climates, such as southern Africa and India, results show that doubled carbon dioxide levels, and their associated climate change impacts, increase yield by 8 percent, an increase that's driven by improved crop water productivity of up to 50 percent. true

Explanation: do you want one?

Growing crops does not raise the carbon levels and does not cause global warming ;  ( i.e. the statement in the question is  False ).

Crops/plant make use of carbon dioxide in the atmosphere during photosynthesis, releasing oxygen and energy into the atmosphere as a by product from photosynthesis.

Global warming is caused by the presence of green house gases in the atmosphere and the removal of CO₂ by plants from the atmosphere during photosynthesis helps with reduction of a green house gas ( CO₂ ).

Hence we can conclude that Growing crops does not raise the carbon levels and does not cause global warming .

Complete question:

Corvids are a large family of birds that includes many species of ravens, jays, crows, and magpies. It was recently discovered that numerous birds in this family are an important vector for the West Nile virus because infected mosquitoes may pass the virus to these birds. Not to mention other species: there are over 35 species crows across the world alone and more than 3,500 species of mosquitoes across 41 different genera. Taken together, these facts demonstrate that it is critical that global societies and scientists

A) use more detailed common names to identify species,such as the "violet crow" or the "American crow."

B) use the genus and specific epithet scientific name to identify taxa.

C) use DNA sequences when referring to a particular species.

D) track diseases like West Nile virus using remote sensing technology on birds to help predict illness spread.

E) invoke higher levels of the classification system, such as kingdom and domain, when referring to a species.

Answer:

D) track diseases like West Nile virus using remote sensing technology on birds to help predict illness spread.  

Explanation:    

The West Nile virus affects many animals, among which there are many bird species. Birds turn to be one of the most important ones, not only because the virus keeps on nature through the cycle mosquito-bird-mosquito, but also because they act as dispersal organisms that carry the virus through long distances.

Due to its mortality and the many organisms it affects, it becomes a need to track the affected birds by the West Nile virus to make prevention through predictions about the distribution area and the periods in which it is more feasible for the virus to attack. It is particularly interesting to apply these tracking technologies to birds. They are severely affected by the West Nile virus and might carry and spread it faster in broad areas due to migration.

The letter answer to the matching image is as follows:

The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. It can significantly be divided into two phases. They are as follows:

The Interphase of the cell cycle is the longest phase which consists of three phases. They are the G1 phase, S-phase, and G2 phase. In this phase, the cell replicates its genetic content and appears to be in a normal state.

In metaphase, the chromosomes usually align in one plane and form an equatorial plate. Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and centromeres migrate to opposite poles.

In telophase, two sets of daughter chromosomes reached the opposite poles and are converted into chromatin thread. After karyokinesis, the cytoplasm gets converted into two equal parts. This is known as cytokinesis.

Therefore, the letter answers to the matching image is well described above.

Plants release approximately 130 billion tons of oxygen during the process of photosynthesis. As a consequence of photosynthesis, oxygen is released by plants. However, it is estimated that plants actually emit 130 billion tonnes of oxygen annually through photosynthesis.

The biochemical process known as photosynthesis is used by plants, algae, and some bacteria to produce glucose (a form of stored energy) and oxygen from sunlight, carbon dioxide, and water. In particular, the chlorophyll, a type of green pigment found in the chloroplasts of plant cells, is where this process occurs.

Chlorophyll in plants absorbs sunlight during photosynthesis, which gives water molecules the energy to divide into hydrogen and oxygen. Using the hydrogen, glucose is created from carbon dioxide, which is subsequently used as an energy source by the plant's different cellular functions.

An organism that cannot synthesize organic compounds from inorganic substances and therefore must take in organic food is called a consumer or heterotrophs.

An organism that is unable of producing its own substance must ingest organic materials created by or found in other species since it is unable to manufacture its own organic carbon-based molecules from inorganic sources.

As heterotrophs are unable to produce their own food, they must consume it or absorb it. Heterotrophs are also referred to as consumers because of this. All types of animals, fungi, as well as numerous protists and bacteria, are consumers. They might eat other heterotrophs, autotrophs, or organic compounds produced by other creatures.

Hydrophobic (fearful of water) amino acids are mostly found inside globular proteins (option A)

Globular proteins are the most abundant proteins in nature and are named after their roughly spherical shapes. The globular proteins come in a wide range of three-dimensional structures. Almost all globular proteins contain a significant number of -helices and -sheets folded into a compact structure stabilized by both polar and nonpolar interactions. The globular three-dimensional structure forms spontaneously and is maintained by interactions between the amino acid side chains. Most of the time, the hydrophobic amino acid side chains are buried, tightly packed, in the interior of a globular protein, away from water.

In meiosis, homologous chromosomes separate in step a, which is called "anaphase I," and four haploid nuclei are formed in step b, which is called "cytokinesis II."

During anaphase I of meiosis, homologous chromosomes, which consist of one chromosome from each parent, separate and move toward opposite poles of the cell. This ensures that each resulting cell receives only one copy of each chromosome pair.

Anaphase I is a crucial step in meiosis as it ensures the distribution of genetic material between the daughter cells is randomized and contributes to genetic diversity.

Following anaphase I, the cell enters cytokinesis II, the second stage of cell division in meiosis. Cytokinesis II involves the physical separation of the two cells formed after anaphase I, resulting in the formation of four haploid nuclei, each containing a single set of chromosomes.

These nuclei go on to further undergo a process called "telophase II" to form four distinct haploid cells, known as gametes, which are essential for sexual reproduction.

High antigenic variation through increased mutation rates. The biological property of a pathogen that could block the successful design of an effective vaccine is having a high antigenic variation through increased mutation rates.

Antigenic variation is a biological property of pathogens that involves changes in their antigenic structure, and it could block the successful design of an effective vaccine. Increased mutation rates cause the emergence of new antigenic variants that are different from previously existing ones. This makes it challenging to design a vaccine that targets all the existing antigenic variants, particularly if they are continually emerging or evolving. This means that even if an effective vaccine is intended for a particular variant, it may not be effective against other variants, limiting its efficacy.

Antigenic variation is common in RNA viruses like influenza viruses, human immunodeficiency virus (HIV), and coronaviruses like SARS-CoV-2, which causes COVID-19. The influenza virus has a high mutation rate, which explains why people need to get vaccinated annually because the vaccine efficacy reduces due to the emergence of new strains. HIV also undergoes antigenic variation, which makes it challenging to design a vaccine that targets all existing strains.

In conclusion, the high antigenic variation through increased mutation rates is a biological property of pathogens that could block the successful design of an effective vaccine.
