eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell's survival.
The chemical division process called mitosis is split into the following 6 steps, such that: interphase<span>, prophase, </span>metaphase<span>, anaphase, telophase, cytokinasis. The firts step of mitosis is characterized by the presence of one cell, but in the end of process there exists two identical cells.</span>

Explanation:
since runoff can be caused by little rainfall but in abundance of vegetation then it may decrease since they stop or slow down it's flow but runoff can not be affected by rocks since the velocity may even wear it
Answer:
Since both Anthony and Sara are healthy carriers of the gene that causes cystic fibrosis, the chance of having a child with this disease are 1:4 (option D).
Explanation:
The inheritance pattern of cystic fibrosis is autosomal recessive, and considering that both parents carry the abnormal CFTR gene, it can be said that the parental genotypes are:
<em>Anthony N/Qf
</em>
<em>Sara N/Qf
</em>
Where N is the normal gene and Qf is the abnormal gene.
Since this is an autosomal recessive disorder, only the homozygosity of the defective allele will cause the disease to manifest
:
N/Qf X N/Qf
<em>Alleles N Qf
</em>
<em>N N/N N/Qf
</em>
<em>Qf N/Qf Qf/Qf
</em>
- The chances of having a healthy child are 25%.
- The chances of having a carrier child are 50%.
- The chances of having a child with cystic fibrosis are 25%.
Therefore, the chance of Anthony and Sara having a child with cystic fibrosis is 1:4.
