Answer:
transparent
Explanation:
translucent is almost see-through, and opaque is barely see-through
Answer:
A. Both in mitosis and meiosis (II)
B. Mitosis
C. In both
D. Meiosis
E. Mitosis
Explanation:
Prior to every case of cell division in both mitosis and meiosis, the cell always ensures to duplicates its contents including its chromosomes. In both cases of cell division, the sister chromatids separates, apart from in meiosis I where homologous chromosomes separates to opposite poles. Only one cellular division occurs in mitosis which is involved in the growth and development of the diploid individual but in meiosis, two divisions takes place in the gametes (both male and female) to ensure that the haploid number of chromosomes is transfered from both parents each to the offspring ensuring a constant diploid offspring. Thus a diploid parent cell always produces a haploid daughter cell in the gametes during meiosis. In mitosis, the daughter cells are always identical to the parents cells.
Answer:
<em>The correct option is B. Alleles</em>
Explanation:
The punnet square can be described as a diagram which shows the outcomes of a cross. A punnet square will help us know what will be the probability for a particular trait to occur in the offsprings.
Genes might have the same or different alleles. If the alleles for a gene are similar in an organism, the organism is said to be homozygous for the trait. If the alleles are different, then the organism is termed as heterozygous.
A dominant allele is the one which which suppresses the effect of the recessive allele. A recessive allele gets masked by a dominant allele.
Answer:
Please find the complete paragraph below; the missing words are inputed in bold.
Explanation:
One of the most important bioethical issues facing us today is the issue of _____EXTINCTION____or a loss of biodiversity
2. Defined as variation of life on Earth __BIODIVERSITY___is the number and relative abundance of different __SPECIES__.
3. It is estimated that there are as many as __8.7 million__ species in the world though as few as __2.3 million_have actually been identified.
4. As the human population grows and demands more resources, ___BIODIVERSITY_ is threatened.
5. Human activities contribute to habitat loss, especially in the world's coral reefs and tropical rain forests. As a result, some organisms face __EXTINCTION_or the death of their species
6. The growth of the __HUMAN___ population has destroyed up to 25% of _BIODIVERSITY__ and threatened another 30% statistics are similar for __ECOSYSTEM___ .
7. Humans also face __NEGATIVE___ consequences in that we are dependent on the ecosystem we are destroying for everything from food to raw material.
Answer: Both the mouse and human beings are encoding the proteins having similar functions.
Explanation:
The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.
Option A is incorrect because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.
Option B is incorrect because amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.
