The correct answer is option A) The DNA in one species of bacteria can be exchanged with an unlike species of bacteria.

Phylogenetic trees are very helpful in tracing lineages and categorizing the animals on the basis of their genetic makeup so that evolutionary relationships between organisms may be established. The DNA of one species of bacteria can be exchanged with an unlike species of bacteria by a process known as horizontal gene transfer. Horizontal gene transfer (HGT) is also known as lateral gene transfer. In HGT, the transfer of DNA does not occur through lateral gene transfer like in case of transfer of DNA from parents to progenies. We consider parents as the most closely related to the progenies because their DNA is more or less same as that of progenies. But in HGT, a bacteria can transfer its genes to a totally unrelated strain of bacteria  via conjugation, transformation or transduction. Since the DNA is being incorporated to an unrelated strain, in a phylogenetic tree the unrelated strain will show up as a related strain to the bacteria from which is has received the DNA through HGT even though it is unrelated. This is how it will create hurdle in tracing lineages and classifying bacteria.

Please helpme on time limit and explain
weqwewe [10]

Answer:

Net force is 100 N

Explanation:

You will use the formula to find the net force/force.

mass = 0.05 kg

acceleration = 2000 m/s^2

F = m × a

F = 0.05 kg × 2000 m/s^2

F = 100 N (Newtons)

Hope this helps, thank you !!

A eukaryotic mutation upstream of a particular gene has been identified that changes the sequence of the TATA box to GATA. How w
Allushta [10]

Answer:

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.

Some animals in grasslands can obtain water they need from plants.
Sati [7]

The statement given in this question is TRUE; Some animals in grassland can obtain the water they need from plants.

Grassland is a biome that is characterized by wide range of temperature and uniform distribution of rainfall all through the year. The major plants found in the biome are grasses and herbs. The soil in the biome is not fertile enough for trees to survive there. Different animals can be found in the biome and some of the animals has drought resistance capacity. Some of these animals obtain their water requirement from the grasses, which they consume.

Which of the following is not a characteristic of pioneer species ?
Irina-Kira [14]

Answer:

They remain in an environment,even as more competitive species arrive

Explanation:

Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.

Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:

- They facilitate environmental change, making an environment more habitable for other species.

- They tolerate a wide range of environmental conditions.

- They are capable of colonizing a barren environment, as in primary succession.

However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.
