Answer:
monohybrid cross
Explanation:
An experiment during which two heterozygous F1 individuals are bred and produce two different phenotypes for a single trait is termed a monohybrid cross.
The hypothesis explaining the source of traits of offspring was changed due to new methods. Thus, this is an example of:
A hypothesis changing because a new scientific method was developed.
Answer: cell membrane
such as water, micro-organism
physical process
simple diffusion, osmosis and filtration
such as potasssium permaganate in water,urea a liver waste diffuses from the body and the kidney help in filtering it out
physiological processs
active transport, phagocytosis and pinocytosis
such as soduim-potassium pump, exocytosis
Explanation: transportation in and out of cell is done in different ways listed above but a barrier to this movement is the cell membrane which is an outer covering of the cell. it protect the cell and only some materials can penetrate the cell membrane e.g micro-organism, water e.t.c. the various physical and physiological processes are the various ways substance cna be liquid, solid or gas are transported within or outside the cell e.g food
A) nucleus
Stores genetic information
B) cytoskeleton
Provides support
C) cytoplasm
Regulates transport
D) Golgi apparatus
Processes proteins
E) lysosome
Breakdown and recycle
F) flagellum
Movement
G) mitochondria
Energy harvest
Answer:
Ultimately what makes each cell different despite the fact that they share the same set of DNA is regulation of gene expression, which regulates the expression of genes. In other words, it determines which genes are turned off and which are turned on in a cell. Gene expression can be regulated in many ways; it's mainly centered around molecules like transcription factors that have the ability to turn certain genes on and off and activators, which promote transcription of DNA.
The short answer to this question is cell differentiation. Differential gene expression results from the genes being regulated differently in each cell type, and differential gene expression leads to different cells.
In fact, from the very beginning of our lives, so to speak, when we're developing from a zygote into an embryo, the egg that makes up the zygote in fact already has a sequential program of gene regulation tat is carried out as cells divide, and this program makes the cell become different from each other in a coordinated fashion.
