Answer:
True
Explanation:
Formation of endospore (sporulation) occurs in some organisms such as bacteria. Sporulation occurs during unfavourable environmental conditions. Sporulation is a process to preserve genetic material during unfavourable environmental conditions. The vegetative cell forms a thick-coated, dormant and resistant spore called endospore.
Endospore was discovered by John Tyndall. It is a resting spore and helps bacteria to overcome the unfavourable environmental conditions.
On the return of favourable environmental conditions, the endospore germinates to form new bacteria cell. Since this process does not involve meiosis, the new bacterial cell is genetically identical to the original vegetative cell.
Answer:
The composition of a population's gene pool can change over time through evolution. This can occur by a variety of mechanisms, including mutations, natural selection, and genetic drift. The result is a gene pool that is altered to be attuned to the needs of the population's specific environment.
Answer:
Blank 1 is option 2 and blank 2 is option 1
Explanation:
A common misconception is that interphase<span> is the first stage of mitosis. However, since mitosis is the division of the nucleus, prophase is actually the first stage. In </span>interphase<span>, the cell gets itself ready for mitosis or meiosis.</span>
Answer:
Endoderm
Explanation:
The embryo has three germ layers. The ectoderm, mesoderm, and endoderm. The endoderm is the innermost layer. Other than the endocrine glands, the other tissues that develop from the endoderm are the gastrointestinal tract, urinary and auditory system, and the respiratory tract.
