Answer:
Sexual reproduction.
Explanation:
Like most mammals, giraffes produce sexually, meaning that both parents contribute to the DNA of the offspring.
Answer:
उनकी उच्च स्थिति और प्राकृतिक शिकारियों की सापेक्ष कमी के बावजूद, पांडा अभी भी जोखिम में हैं। मनुष्यों से गंभीर खतरे जंगली में सिर्फ 1,800 से अधिक पांडा छोड़ गए हैं पंडों मुख्य रूप से दक्षिण-पश्चिम चीन के पहाड़ों में समशीतोष्ण जंगलों में रहते हैं, जहां वे लगभग पूरी तरह से बांस पर रहते हैं। उन्हें हर दिन लगभग 26 से 84 पाउंड खाना चाहिए, यह इस बात पर निर्भर करता है कि वे बाँस के किस हिस्से को खा रहे हैं। वे अपनी बढ़े हुए कलाई की हड्डियों का उपयोग करते हैं जो विरोधी अंगूठे के रूप में कार्य करते हैं।

Answer:
True statements about transcription:
- Occurs in the nucleus
- Produces single-stranded mRNA using the antisense DNA strand as a template
- Precedes 5' capping and polyadenylation.
Explanation:
Transcription is the process by which a specific fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) molecule, which is then used to synthesize a protein in the ribosomes by a process called 'translation'. In eukaryotic cells, transcription occurs within the cell nucleus which contains the genetic material of the cell. Transcription factors are proteins that bind to DNA regulatory elements (e.g., promoter sequences) located at the 5′ end of the transcription initiation site and thus stimulate transcription. Both mRNA capping (5' cap) and polyadenylation are post-transcriptional modifications that serve to protect the nascent mRNA from enzymatic degradation and help in ribosome binding during translation.
Answer:
Prokaryotic single-celled organisms.
Explanation:
even though many debate on this. the earliest forms of like pretty much began with bacteria. During the Precambrian Timespan most life was composed of these single celled organisms.
Bacteria can convert nitrogen in the air into a form plants can use
