describe how carbon dioxide is produced by respiring muscle cells reaches the alveolar cavitiesin mammalian lungs
Answer:
Hope this helps:
The carbon (iv) oxide which has been produced by the respiring muscle tissue is diffused into the bloodstream in the form of bicarbonates, a process facilitated by an enzyme called carbonic anhydrase. The carbon (iv) oxide is then carried to the lungs.

If glucose is metabolized under completely anaerobic conditions, pyruvate ( Please explain why each answer is wrong or right.)
a. immediately enters the Krebs cycle.
b. is converted by fermentation to lactate or CO2 and ethanol.
c. is converted back to fructose until the concentration of oxygen increases.
d. is converted to NADH.
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.

factors that affect rate of erosion
Answer:
farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.
Explanation:
Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.
The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.
Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.
Other factors that affect the rate of erosion in an area include the following; farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.

CO2 + H20 + light energy --> C6H12O6 + O2
In the chemical reaction above, what does CoH12O6represent?
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.
which process is needed for evolution to occur? PLEASSE HELPPP THIS IS A BIG GRADE
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.

3. The presence of Malaria in many countries has been eradicated and even in parts of Africa, the incidence of Malaria has been reduced substantially. Without endemic malaria from Africa, the sickle cell mutation is purely disadvantageous. What do you think will happen to the percentage of people carrying the Sickle Cell gene over time under the pressures of natural selection
Answer:
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.
3. A branched diagram showing relationships between organisms is a/an– a. amino acid sequence. b. fossil record. c. cladogram. d. DNA sequence.
Answer: your answer would be B
Explanation:
A branched diagram showing relationships between organisms is a cladogram. The correct option is c.
What are the uses of cladogram?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.

In the liver, excess amino acids are broken down into ____________ and rapidly combine with ____________ to produce urea, which is much less toxic to cells.
Answer:
In the liver, excess amino acids are broken down into ammonia and rapidly combine with carbon dioxide to produce urea, which is much less toxic to cells.
Explanation:
The correct answer to the given quested about Urea Cycle is Ammonia and Carbon dioxide respectively and the complete statement will be "In the liver, excess amino acids are broken down into Ammonia and rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells."
What do you mean by Urea Cycle?The urea cycle, commonly referred to as the ornithine cycle, is a series of metabolic processes that converts ammonia into urea (NH2)2CO (NH3).Highly poisonous ammonia is transformed into urea by rapidly combining with carbon dioxide via the urea cycle for elimination. Five years before the TCA cycle was found, this cycle was the first to be identified as a metabolic process. Later, Ratner and Cohen provided a more thorough explanation of this cycle.Thus we can conclude that in the liver, excess amino acids are broken down into Ammonia which is highly toxic to cells and that ammonia rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells.

The smaller a population of organisms of a particular species, the
A.
more likely one of the organisms is to adapt to a changing environment
B.
more likely a mutation is to arise
C.
less likely the species will be able to survive in a changing environment
D.
less likely natural selection is to affect the population
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.

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.
Source: NASA/JPL-Caltech/MSSS
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.
