How does cloning effect the individuals???

Both bacteria and amoeba are unicellular organisms. Bacteria are considered to be prokaryotes, whereas amoebas are considered to

denis23 [38]

Though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.

Both bacteria and amoeba are single-celled organisms. They both have ribosomes.

Bacteria is a prokaryote. It lacks membrane-bound nucleus, mitochondria, chloroplasts or any membrane-bound organelles.

Amoeba is a eukaryote. It has a "true" nucleus containing its DNA and organelles which is responsible for energy production and protein transport.

kondor19780726 [428]

Complete question:

A geneticist crossed fruit flies to determine the phenotypic ratio. The geneticist crossed a fly with blistery wings and spineless bristles (bbss) with a heterozygous fly that had normal wings and normal bristles (BbSs). Which proportion of offspring that are dominant for both traits in would you not expect based on Mendel's law of independent assortment? 1/2 , 4/16, 25% , or 1/4

Answer:

1/2 is the proportion of the offspring that is NOT expected among individuals that are dominant for both traits.

4/16 = 1/4 = 25% of the progeny and the correct expected proportion of individuals that are dominant for both traits.

Explanation:

Available data:

Cross: a fly with blistery wings and spineless bristles with a heterozygous fly that had normal wings and normal bristles
Recessive trait: blistery wings and spineless bristles
Dominant trait: normal wings and normal bristles

Let us say that:

B is the dominant allele for normal wings
b is the recessive allele for blistery wings
S is the dominant allele for normal bristles
s is the recessive allele for spineless bristles

Parentals) bbss x BbSs

Gametes) bs, bs, bs, bs BS, Bs, bS, bs

Punnett square) BS Bs bS bs

bs BbSs Bbss bbSs bbss

F1) 4/16 = 1/4 = 25% of the progeny is expected to be BbSs, dyhibrid individuals, expressing normal wings and normal bristles

4/16 = 1/4 = 25% of the progeny is expected to be Bbss, expressing normal wings and spineless bristles

4/16 = 1/4 = 25% of the progeny is expected to be bbSs, expressing blistery wings and normal bristles

4/16 = 1/4 = 25% of the progeny is expected to be bbss, expressing blistery wings and spineless bristles

Interactions between organisms and their environment impact the organism’s overall population. The jaguar Panthera onca is the l

Anit [1.1K]

Answer:

Predator-prey relation.

Explanation:

A predator is defined as an organism that hunts another individual, whereas a prey refers to the organism that is eaten by the predator. They tend to co-evolve (evolve together). The prey is essential for the predator to survive, while the predator controls the prey populations by hunting some of the individuals.

Predator-prey relations are interactions that occur between two species where one species (prey) represents a food source for the other species (predator).

The turtle (prey) is essential for the survival of the jaguar (Panthera onca), while the jaguar controls the populations of turtles by preying upon them. Therefore, this is a predator-prey relation.

Maru [420]

Answer:

In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is inhibition.

Explanation:

Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.

What is one piece of evidence that some organelles like mitochondria and chloroplasts within eukaryotes used to be independent p

Svet_ta [14]

Answer:

organelles are very similar to present-day bacteria, suggesting a common ancestor.

Explanation:

Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.

Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.

So these organelles are similar to present-day bacteria showing that they have a common ancestor.
