As in all animal cells<span>, the </span>cells<span> of the </span>human cheek<span> do not possess a </span>cell<span> wall. A </span>cell<span>membrane that is semi-permeable surrounds the cytoplasm. Unlike plant </span>cells<span>, the cytoplasm in an animal </span>cell is<span> denser, granular and occupies a larger space. The vacuole in an an animal </span>cell is<span> smaller in size, or absent.</span>
Answer: si un objeto A ejerce una fuerza sobre un objeto B, entonces el objeto B debe ejercer una fuerza de igual magnitud en dirección opuesta sobre el objeto A.
Explanation:
Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.
The failure of homologous chromosomes to separate properly is during meiosis where mutation appear
