10. Maltose is a disaccharide formed by condensation of two molecules of glucose. Which of the
following statements is not true of a molecule of maltose?
a. It contains the same number of carbon atoms as a oxygen atoms.
b. It contains twice as many carbon atoms as a molecule of glucose.
c. It contains twice as many hydrogen atoms as oxygen atoms.
d. It contains more hydrogen atoms than carbon atoms.

What it will be ?

Answers

Answer 1

Answer:

The correct answer is A.

Explanation:

The chemical formula for maltose is C12H22O11. That means there are 22 carbon molecules, 22 hydrogen molecules, and 11 oxygen molecules. You can see that A is untrue because 22 is not equivalent to 11. Meanwhile, all other statements are true.

Question 2: Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.

QUestion 3: Similar body parts may be homologous structures or analogous structures. Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

The rate at which an object weathers is determined by many different variables. For example, compare the two ancient Egyptian structures below.

Compare the obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).
Both structures were carved in Egypt from the same type of rock more 1,000 years ago. However, the obelisk in New York, which was transported there from Egypt in 1881, has since experienced a much higher rate of weathering. What factors likely sped up the weathering process for the structure that was moved to New York?

Answers

Answer:

I just answered this question in your other submission of the question. You can look at it if you want!

The obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).In New York temperature is low,considerable cloudiness with occasional rain showers.

What are factors that can speed up the process of weathering?

The amount of rainfall and the temperature can influence how quickly rocks weather. The pace of chemical weathering is accelerated by high temperatures and heavier rainfall. 2. Compared to comparable rocks living in cold, dry climates, rocks in tropical regions exposed to heavy rainfall and high temperatures weather far more quickly.

Chemical weathering is accelerated by moisture. Hot, humid regions are the ones that weather the fastest. In hot, dry areas, it happens extremely gradually. Ice wedging is not possible without temperature variations.

Significant influences in weathering include physical forces like temperature and humidity, chemical forces like oxidation and carbonation, and biological forces like animal and human activity-related burrowing.

Thus,In New York temperature is low,considerable cloudiness with occasional rain showers.

Red-green colorblindness is a inherited disorder in which individuals have trouble distinguishes
between red and green (or brown and orange) and often confuse blue and purple hues. This
condition is usually found in males, as it is located on the X chromosome.
A man with red-green colorblindness has one brother who has normal version. From which parent did the man inherit colorblindness? Explain how you know using a Punnett square to © 2014 Vanessa Jason (“Biology Roots”
back up your answer.

Answers

Since the colorblindness is located on the X chromosome, the man must have inherited his colorblindness from his mother.

X-linked traits

Women are XX while men are XY.

Also, the X chromosome in XY always comes from the mother.

Since the man is affected for colorblindness but his brother is not, it means that only one X chromosome of the mother is affected while the father can be affected or otherwise.

Assuming the father is free from colorblindness and the allele is represented by c:

          [tex]X^cX[/tex]    x    [tex]XY[/tex]

      [tex]X^cX[/tex]    [tex]X^cY[/tex]    [tex]XX[/tex]    [tex]XY[/tex]

Thus, the man's genotype is  [tex]X^cY[/tex] and it comes from the mother.

Read the scenario.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.

The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.

Which question most closely relates to the biologist's observations and collected data?

Are the golden frogs succumbing to a fungal infection?

Did the golden frogs migrate to a new habitat?

Why was a copper mine built so close to the stream?

Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?

Answers

Answer:

The most likely answer would be D, Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?

Explanation:

The golden frogs live either close to the stream or in it, which means the acidity and toxicity could kill them.

Answers

The scientific law of one organism feeding off other where energy is transferred from one form to another is known as the law of conservation of energy.

How the sun is the primary source of energy for ecosystems?

Energy from the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.

The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.
