The principle of segregation given by Gregor Mendel based on his experiments with the pea plants states that alleles of a gene for any trait are segregated during the formation of the gametes. Therefore, a gamete contains only one allele of a gene. When the male and female gamete combines during fertilization, the two alleles (one from each gamete) combine to form the gene.
Hence, the correct answer is 'Option B - A gamete carries one allele for a gene'.
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।

- It contains several digestive enzymes such as glycosidases that break down complex sugars, proteases that break down proteins, and sulfatases that hydrolyze sulphur-containing compounds, and also digest worn out organelles, and engulfed viruses and bacteria.
- and helps to remove wastes from the white blood cell.

Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
