Answer:

In the chemical reaction , [tex]C_6H_1_2O_6[/tex]  represent glucose.

Explanation:

This chemical reaction is used in the process of photosynthesis . A plant absorbs water, carbon dioxide, and light energy when producing glucose and oxygen during photosynthesis. Since glucose is required for cellular respiration, it is extremely essential. The chemical energy in the glucose molecule is transformed into a shape that the plant can use for growth and reproduction during cellular respiration.

Hence , the answer of the given question is Glucose.

Answer:

Option A

Explanation:

The pH of a solution is determined by the following formula

pH = -log [H+]

Here H+ is the hydrogen ion concentration

Thus, if pH is known one can determine the hydrogen ion concentration by taking its antilog.

Hence, option A is correct

Explanation:

Answer: D. Genetic mutation

Explanation:

For evolution to occur, there must be a genetic mutation in the genome of an organism such that a new allele is formed.

If this mutation occurred in the sperm and/or the ovum, the mutation will then be passed on through reproduction to the next generation. This leads to more of the subsequent generations having that mutation thereby leading to evolution.

Answer:

D.species diversity

Explanation:

its D  because biodiversity,includes to all the many plants, animals, fungi, and microorganisms. And includes the many variety of ecosystems what's found on Earth. Ecosystem diversity, describes all of the different type of habitats around the world.

This mutation likely have a bad consequence for the organism - No, because the mutation will not code for a different amino acid.

Amino acid sequences are formed by the translation and transcription from DNA sequence to mRNA and finally amino acid sequences.

Thus, this mutation will not change the amino acid so the answer will be No.

Answer:

The end rocky part of two continents has similar composition, the presence of similar fossils of animals and climate

Explanation:

Alfred Wegener find out the end rocky part of two continents has similar composition, the presence of similar fossils of animals and climate so he presented the theory of continental drift that occurs 200 millions years ago. The main reason for the rejection of Wegener's hypothesis because he provides no mechanism for the movement of the continents. Wegener thought that the force of Earth's spin was sufficient for the drifting of continents from each other but other scientists says that it is too weak to drift the continents.

Answer: your answer would be B

Explanation:

A branched diagram showing relationships between organisms is a cladogram. The correct option is c.

An evolutionary tree that depicts the relationships between species' ancestors is called a cladogram.

In the past, cladograms were created using similarities among species' phenotypic or physical characteristics. Today, cladograms can also be created using similarities among organisms' DNA sequences.

A cladogram employs lines that diverge and then converge at a clade, a collection of creatures with a recent common ancestor.

Cladograms come in a variety of shapes, but they all contain lines that diverge from other lines. It is possible to follow the lines back to where they split off.

Cladograms provide a framework for comprehending the rate of evolution of groupings of animals as well as the relationship between their evolutionary history and the planet's changing climate and geography.

Thus, the correct option is c.

Answer:

B.

Explanation:

A is wrong because pyruvate would enter the Krebs cycle under aerobic condition (when oxygen is present). Hence the name aerobic cellular respiration

C. I do not really too much about fructose or the concentration of oxygen, but I can assure that this answer choice is not correct.

D is wrong because NADH would be converted from NADP+. Either with oxidation or reduction, and this helps to keep this process going.

B is correct because fermentation is another word for anaerobic cellular respiration. The process takes place with the absence of oxygen. It either goes through Alcoholic or lactic acid fermentation.

Answer:

Brown fat cells are present in our body which helps in regulating the body weight. The main role of brown fat is to produce heat when the temperature of body is going down or when we are feeling cold. They burn energy in order to produce heat and burning energy comes from white fat which can be translated into weight loss. This is how the brown fat helps in weight management.

The brown fat is activated by cold temperatures and it helps our body fast our metabolism by providing heat by burning energy.

The percentage of people carrying sickle cell gene increases.

Explanation:

People carrying the Sickle Cell gene have low chance of Malaria because the sickle cell enables the body to detoxify abnormal red blood cells from the body. When the malarial parasite attacks on the cells of the body, the molecular machinery for cleaning up the waste is already present in the body.  Those places where malaria is common, the people having sickle cell because the sickle cell show resistance against malarial disease.

Answer:

The correct answer is - D. less likely natural selection is to affect the population

Explanation:

The larger population of a species tends to produce more mutant individuals per generation than a smaller population per generation. In a larger population, it assists to get more genotypes and gets optimal genotypes quicker than smaller populations.

In larger populations, the process of natural selection is more effective and for the smaller population   Second, natural selection is less likely to affect the population which leads to less genetic diversity or change in order to survive due to stochastic sampling error  as some allele loss in random selection.

the answer is sensory (afferent) division

A series of missions to the moons of Jupiter and Saturn has revealed their potential to harbour life. Nina Notman looks to the skies

After a series of mission failures, July 1965 saw the first successful flybys of Mars. The US Mariner 4 became the first spacecraft to take close up pictures of another planet, beaming 22 images of the impact-cratered Martian surface back to Earth. Since then, more than 20 successful missions have explored the red plant’s atmosphere and surface.

Thanks to the images and data collected– and by telescopes, both on earth and in space – we now know that billions of years ago, Mars had the three critical ingredients for life. It had an abundance of the chemical building blocks, liquid water on its surface and an energy source (volcanic activity) to power the chemical reactions that make life possible (on Earth that energy source is the sun). Today, the inhospitable surface of Mars is thought to be unsuitable for life, but the possibility of life existing deep beneath its frozen surface hasn’t been ruled out. To date though, no evidence of life – ancient or otherwise – has been found. Mars being habitable, it turns out, doesn’t mean it actually has a habitat.

Mars has all the ingredients for life – water, chemicals and energy – but no signs of living things yet

The search for Martian life is ongoing, with a further three missions to Mars planned to launch over the next few years. Longer-term, a number of space agencies are also aiming to collect samples from Mars and return them to Earth for more in-depth analysis. And the search for signs of extraterrestrial life is stretching to the depths of our solar system and beyond.
