What organelles could you find in lettuce cells but not mouse cells?

Answers

Chloroplasts are found in lettuce cells but not mouse cells.

What is the function of chloroplasts?

A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.

Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells.

the organelles you will never see in a mouse cell is chloroplasts and a cell wall. but they are found in the plant.This is because they carry out photosynthesis.

Why is it important for science and society to communicate about stem cell research?

Answers

Stem cell research has many potential future uses. Communication is vital because:
1) Through worldwide collaboration, progress is faster
2) Ethical issues may impede progress if not carefully considered

Explanation:

Why isn't mitochondrial DNA a unique identifier? a. Mitochondrial DNA is inherited through the maternal lineage.
b. All female offspring inherit their mother's mitochondria, and therefore the same mitochondrial DNA.
c. As a result, all female family members that share a maternal lineage would have the same mitochondrial DNA.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
e. All offspring inherit their father's mitochondria, and therefore the same mitochondrial DNA.

Answers

Answer:

a. Mitochondrial DNA is inherited through the maternal lineage.

d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.

Explanation:

DNA is the genetic material. Nuclear DNA profiling is used to identify a person since each individual has unique DNA. Mitochondrial DNA exhibits maternal inheritance. All the offspring of a female share the same mitochondrial DNA. Therefore, all the individuals that are related by maternal lines, share the same mitochondrial DNA. The profiling of their mitochondrial DNA would not allow the identification of a person when individuals share maternal lines.
