The number of mitochondria are increased during interphase. True or False? The answer is True
Hemoglobin is a special protein in the blood that captures and carries oxygen.
Answer:
E: specific proteins that are made by a cell under particular conditions
Explanation:
It is only specific proteins that are made by a cell under particular conditions can't be obtained from a genome sequence. In order to get information about this protein we need proteomics.
Genome sequence gives us an idea of nucleotide sequence of DNA and RNA molecules not proteins. Regulatory sequences such as promoters, enhancers, insulators, UTRs etc. all are a part of genome, rRNA genes are part of genome sequence too, non coding repetitive repeats and intron regions are also a part of genome sequence itself so option A, B & D are incorrect. Option C is also incorrect because amino acid sequence of proteins can also be determined by genome sequences because each nucleotide triplet which is known as codon refers to a specific amino acid. Option E is correct because by genome sequence we can easily get to know about amino acid sequence but not about specific protein which is synthesized at a particular condition.
The correct answer is:
Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.
Explanation:
Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
Answer:
D. Fossil record.
Explanation:
The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.
