You have learned that humans have a total of 46 chromosomes and that chimpanzees have a total of 48 chromosomes. Use other textb

ooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you? What did your research suggest about the relationship between chromosome number and organism complexity?

Answer:

The correct answer is included in the Explanation section

Explanation:

An organism with considerable more chromosomes than humans: the plant <em>Ophioglossum reticulatum</em> with 1260 chromosomes.

An organism with considerable fewer chromosomes than humans: the ant <em>Myrmecia pilosula</em> with 1 chromosome.

It might be thought that the chromosome number of a species is directly related to its complexity, meaning that an organism with a large number of chromosomes is more complex than an organism with a small number. However, this is not true. Chromosomes are structures of coiled DNA, and its number indicate how the cells wrapp their genomic material when they reproduce. The number of chromosomes is not related to the organism complexity, but rather the number of genes and their function.

Of the following experimental results, which is the best evidence that photosynthesis is more efficient at certain wavelengths o
GarryVolchara [31]

Answer:

The correct answer will be option-C

Explanation:

The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.

The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.

In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.

Thus, the selected option is the correct answer.

Why don't cyanobacteria and bacteria reproduce by mitosis? Because:
AVprozaik [17]

Answer:

They do not contain chromosomes. (Ans.C).

Explanation:

Cyanobacteria also known as blue-green algae, they are heterogeneous group of photosynthetic prokaryotic organisms. Like prokaryotes such as bacteria, cyanobacteria lack endoplasmic reticulum, mitochondria, membrane bound nucleus, and Golgi apparatus. Bacteria are simpler than other organisms, and single celled microbes.

Both bacteria and cyanobacteria reproduce through the asexual method either by binary fission in unicellular, multiple fission in colonial form or by spore formation, and fragmentation in filamentous species.
