Which germ layer is destined to become the inner lining of body organs

The endoderm is the germ layer that becomes the body cavity's inner lining.

What factor allows organisms such as planarian worms and plants to regenerate new individuals from fragments of parent organisms

totipotency of cells

What kind of bacterium cannot tolerate oxygen

The bacterium that cannot tolerate oxygen is Anaerobes, but there are different kinds and each has different tolerances when it comes to oxygen. Obligate Anaerobes can get killed by oxygen. Facultative anaerobes those can grow without oxygen. Aero-tolerant anaerobes they never use oxygen BUT they can tolerate it. Microaerophiles require i tiny bit of oxygen but anymore than the little bit they need and they cannot grow.

In what cycle of viral replication does the virus destroy the host cell

During the cycle of viral shedding, the virus has made copies of itself and the host cell is no longer useful. The host cell then dies, and the new virus cells then must find a new host.

What method of classification is based on DNA and evolutionary relationships

phylogeny

What term describes bacteria that stains pink with gram stain and has a rounded shape

gram negetive coccus

What is the process by which bacteria remove nitrogen from the air and make it available to plants

Bacteria performs nitrogen fixation, which involves converting the atmospheric nitrogen (N2) into usable organic nitrates (NO3-). Said bacteria are often referred to as nitrogen fixating bacteria. The process is sometimes called nitrification.

Scientists have been able to give plants genes from bacteria to help them do a beeter job. This process is called recombinant DNA technology. Nitrogen fixing bacteria are in root nodules on legumes and maybe some other plant groups.


Converts nitrogen in the air to nitrates.
What language is the basis of the names used in taxonomy

Latin

Which of these is an example of a clone

a rooted cutting from a plant

Storm Trooper:)

Which of these is an example of a domain of life

Eukarya

How do bacteria exchange genetic information

on plasmids in a process called conjugation
The bacteria exchanges genetic material when they are divided into two.but for i know bacteria do not exchange genetic material....
transformation,transduction and conjugation

Which of these is not a way that bacteria are classified

by the diseases they cause

What about some bacteria is important to humans in terms of our being able to make proteins and nucleic acids from the foods we eat

they can fix nitrogen

Which letter in this figure showing a zygotic life cycle indicates where meiosis occurs

guess a it is right
