a. In the lag phase, cell death exceeds cell division. FALSE
Is the period when the bacteria are adjusting to the environment.
b. In the death phase, bacterial growth may cease as a result of oxygen and nutrient depletion. TRUE
Is characterized by an exponential decrease in the number of living cells.
c. Bacteria typically divide by binary fission, producing two daughter cells. TRUE
This is the most common way of division. The duplicate's DNA and part in half.
d. The generation time of bacteria may vary from species to species. TRUE
As in all species, the generation time will always vary.
When new habitat is made available, organisms can diversify rapidly. this can be gradual or punctuated this process called as adaptive radiation.
<h3>What is Habitat?</h3>
The term "habitat" in ecology refers to the variety of resources, physical characteristics, and biotic elements that exist in a region and are necessary for a specific species to survive and reproduce. An animal's habitat can be thought of as the outward representation of its biological niche.
Thus, the term "habitat" refers to a specific species and is fundamentally distinct from ideas like the environment or vegetation assemblages, which are better described by the term "habitat-type."
The physical elements could consist of things like soil, moisture, temperature range, and light intensity, for instance. The availability of food and the existence or absence of predators are examples of biotic variables. Every species has certain habitat needs; habitat generalist species can survive in a variety of environmental circumstances, whereas habitat specialist species need a specific habitat.

#SPJ4
Answer:
The DNA enzyme; Helicase
Explanation:
DNA chains are "unzipped" by the enzyme Helicase; which requires energy to function
C. Birds have the same arrangement of bases as flowers
Answer:
A) repressors
Explanation:
A transcription factor is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to specific DNA sequence. The function of TFs is to regulate-turn on and off genes-In order to make sure that they are expressed in the right cell, at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth and cell death throughout life.
