Answer:

They can be harmful.

Explanation:

Prokaryotes are the organism that do not have nucleus and lacks the membrane bound organelle. Eukaryotes have well defined nucleus and contains the membrane bound organelle.

Th prokaryotes includes the small bacteria and other small organism. The bacteria can cause harmful disease in humans. They can cause cancer or can mutate the genetic constitution of the organisms. The prokaryotes can destroy the products that are harmful and their consumption can destroy the human health.

Thus, the correct answer is option (3).

In the infamous anthrax attacks of 2001, several letters were received at the offices of two U.S. senators and verious new media

Len [333]

Answer:

The dry-out material contains spores of anthrax-causing bacteria

Explanation:

Anthrax is a disease caused by a bacteria known as Bacillus anthracis. Susceptible animals get infected by anthrax when the spore of the bacteria gets into their bodies, become activated, multiply and produce toxins.

The spore serves primarily as a propagating structure and also as an agent for transmitting infections. It can be transmitted by air, water, food or any other means. Bacterial spores usually have the capability to tolerate harsh environmental conditions and only become inactivated when conditions are favourable.

The dry granular powdery material constituent of the letters received by the U.S. senators must have been spores of Bacillus anthrasis

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the

krek1111 [17]

Answer:

The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).

Explanation:

A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.

In mitotic telophase:

Chromatids, which are chromosomes, are found in the cell poles.
It initiates the formation of the nucleus membrane.
The chromosomes begin to turn into chromatin.
Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.

The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.

The other options are not correct because:

a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.

c. A somatic cell does not experience meiosis.

Infer: what is the relationship between the evolution of bipedalism, the increase in cranial capacity, and the decrease in tooth

noname [10]

When the organism become bipedal, they walk with 2 legs so there are 2 arms that were unused. Some of them try to use that hand by grabbing stick or stone, leading to tools. They start to think more to develop tools and their brain capacity become increased.
The ability to use stone tools will help in food digestion since it can break the food easier. This reduces the needs for bigger teeth/jaw.
