Answer:
duplication RNA
Explanation:
Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

What is cell?
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically,cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
Therefore,The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.

PLEASE HELP!!!!!!
Red blood cells transport oxygen to every cell in the body. This oxygen is needed to release energy stored in glucose molecules. Red blood cells also transport carbon dioxide, a waste product produced by cells, back to the lungs where it is exhaled. When a person exercises, his or her muscle cells consume more oxygen and produce more carbon dioxide. The body responds by increasing its breathing rate and heart rate to supply more oxygen-rich blood to the muscles and carry away more wastes. Explain how this is an example of maintaining homeostasis.
Answer:Read Passage Below
Explanation:
Cells store waste in ________.
Answer:
Vacuoles
Explanation:
Cells store waste in organelles called "lysosomes." Thus, the complete statement is "Cells store waste in lysosomes"
Where do cells restore waste?Lysosomes are membrane-bound organelles found in cells. They contain digestive enzymes that can break down various types of biological molecules, including waste materials.
Lysosomes play a crucial role in cellular waste management and recycling processes.
They are responsible for breaking down and recycling cellular waste, unwanted materials, damaged organelles, and foreign substances that enter the cell. By storing waste and containing the digestive enzymes, lysosomes help maintain cellular cleanliness and proper functioning.

Which organelle plays an important role during mitosis, helping to move chromosomes around the cell
a
Oь
Ос
Od
vacuoles
Golgi bodies
chloroplasts
centrioles
Answer:
Explanation:
Duplicated centrioles are responsible for moving chromosomes during mitosis.
They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.
It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.
Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.
They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.
Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.
These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.
During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.
At the end in telophase, where nuclear membrane becomes visible it disappears.
In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.
