Which one of the following is an example of a prokaryote?

A.
HIV virus
B.
lactobacillus bacteria
C.
amoeba

Answers

Answer 1

Answer: Option B

See,

HIV Virus is not the answer because viruses are neither prokaryotes nor eukaryotes.

So, option A. is not an option.

Lactobacillus bacteria is a prokaryote (Your answer)

Amoeba is an eukaryote.

Hope it helps!!

Answer 2

Lactobacillus bacteria is an example of a prokaryote. Therefore, option (B) is correct.

Prokaryotic, unicellular Lactobacillus bacteria lack nuclei and membrane-encased organelles. The cytoplasm of prokaryotes like lactobacillus has a single circular DNA molecule. The nucleoid grows. Unlike them, eukaryotic organisms contain nuclei and membrane-bound organelles.

Lactobacillus bacteria preserve gut health. They improve digestion, balance gut flora, and gut health. By fermenting lactose into lactic acid, several lactobacillus species preserve and sour yoghurt.

Non-prokaryotes HIV and amoeba. Acellular retrovirus HIV is neither prokaryotic nor eukaryotic. Lactobacillus is simpler than amoeba, a eukaryotic organism with a nucleus and membrane-bound organelles.

Lactobacillus bacteria aid digestion and fermentation. HIV is a virus, and amoeba is a complex eukaryotic organism. Therefore, option (B) is correct.

Explanation:

hope it will help you

The correct option for the image showing carbon dioxide moving is the biosphere to the atmosphere. Therefore, the correct option is C.

Respiration and combustion are the main processes by which carbon dioxide [tex]\rm (CO_2)[/tex] is transferred from the biosphere to the atmosphere. In the biosphere, which is made up of all living things and organic matter on Earth, plants and animals release carbon dioxide as a result of consuming oxygen [tex]\rm (O_2)[/tex].

Additionally, human activities such as the combustion of fossil fuels for energy also contribute significantly to atmospheric emissions of carbon dioxide. This human-caused process is a major contributor to the increase in atmospheric carbon dioxide levels, which is a major contributor to climate change.

Explain (3) specific differences OR (3) specific similarities between chimpanzee and human behavior. Do you think humans have a moral obligation to preserve the habitat of the chimpanzee. Why? OR Why not?

Answers

Jane Goodall is an expert on chimpanzees that live in the wild and made  most significant discovery about chimpanzees.

Jane Goodall is an expert on chimpanzees that live in the wild. The most significant discovery she made about chimpanzees during the early years of her research is that chimpanzees and humans have similar traits social behavior, eating habits, and the ability to make tools. This discovery fundamentally changed how we think about the closest living relatives of humans.Because chimpanzees and humans have so many moral similarities, I firmly believe that it is our moral responsibility to maintain the chimpanzees' ecosystem. In addition to being informative for us, I think they should be permitted to continue living in their existing habitat. Given our resemblance to humans, we would seek assistance if our environment were in danger.

So we can conclude that chimpanzees are very similar to human beings by the above points in terms of behavior.

Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.

Moreover, deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world.

Hence, the loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people.

in human, the allele for hemophilia, h, is recessive. Which phenotype is displayed in an individual with the genotype XhY

Answers

Hemophilia is a genetic disorder caused by the recessive allele of a diallelic X-linked gene. Hemophilic men carry the recessive allele in their X chromosome. The man XhY is hemophilic.

What is hemophilia?

Hemophilia is a hemorrhagic affection that occurs because the blood does not coagulate as it should in normal conditions.

Hemophilia is a genetic X-linked disorder caused by the recessive form of a diallelic gene.  

The recessive allele h codes for hemophilia, The dominant allele is H and codes for the normal phenotype.

In the case of women, this gene expresses complete dominance, meaning that an heterozygous woman is normal but carrier.

Any man who gets the X chromosome carrying the recessive allele expresses the affection.

Let us represent the dominant allele H with the symbol + and the recessive allele h with the symbol -.

Genotypes     Phenotypes                        

X⁺X⁺                 Normal woman

X⁺X⁻                 Normal and carrier woman    

X⁻X⁻                 Hemophilic woman

X⁺Y                  Normal man

X⁻Y                  Hemophilic man                    

In the exposed exposed example, the individual XhY is a man that expresses hemophilia, since he has the X chromosome carrying the recessive allele.
