Suppose a butterfly with 16 chromosomes is able to produce offspring. How many chromosomes would the offspring receive from each
Stella [2.4K]

The irght answer is 8.

Each parent will give half of its chromosomes to its offspring through the gametes (which are haploid cells, containing n chromosomes) which will then fuse (male and female gametes) to form a diploid 2n chromosome cell and will eventually give rise to a new individual.

So each parent will give 8 of these chromosomes to their offspring.

What happens to an enzyme's structure as it exceeds the typical human body temperatur?
valentinak56 [21]

Answer;

The enzyme structure begins to break down intermolecular bonds are broken

enzyme molecules gain kinetic energy.


Explanation;

Enzymes are proteins that play an important function in the body of catalyzing reactions in the body.

Enzymes work best at optimum temperature; low temperature lower than optimum temperatures deactivates them and higher temperature denatures them.

The shape of an enzyme depends on its temperature; when they get too warm they get loose, and at very low temperatures they get too tight. At optimum temperature or at the right temperature then they are just at the right shape and the chemical reactions they catalyze will be at optimal rate.

Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.
PilotLPTM [1.2K]
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.

How did flowers and fruits contribute to angiosperms becoming dominant land plants on earth?
Ainat [17]

Answer: The study, by Dr. Tim Brodribb and Dr. Taylor Field of the University of Tasmania and University of Tennessee, used plant physiology to reveal how flowering plants, including crops, were able to dominate land by evolving more efficient hydraulics, or 'leaf plumbing', to increase rates of photosynthesis.

Explanation: The reason for the success of this evolutionary step is that under relatively low atmospheric C02 conditions, like those existing at present, water transport efficiency and photosynthetic performance are tightly linked. Therefore adaptations that increase water transport will enhance maximum photosynthesis, exerting substantial evolutionary leverage over competing species.

The evolution of dense leaf venation in flowering plants, around 140-100 million years ago, was an event with profound significance for the continued evolution of flowering plants. This step provided a 'cretaceous productivity stimulus package' which reverberated across the biosphere and led to these plants playing the fundamental role in the biological and atmospheric functions of the earth.
