All your cells have the same genes. True or false?

Answers

Answer 1
Answer: That is True! As it says here on a website:All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells.

What molecule makes the trunk of a tree sturdy

Answers

Answer:

Cellulose

Explanation:

trunk is the main axis of a tree that supports the branches and is supported by roots. Cellulose makes it sturdy. Cellulose is the main substance in the walls of plant cells, helping them to remain stiff and upright.

Answer:

Cellulose, that is the molecule that makes a tree sturdy.

Explanation:

The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell.For example, consider these two proteins:1. Phosphofructokinase (PFK) is an enzyme that functions in the cytoplasm duringglycolysis.2. Insulin, a protein that regulates blood sugar levels, is secreted from specializedpancreatic cells.Assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.For each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (Note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)Options:Cytoplasm only, ER --> cytoplasm, ER --> Golgi --> outside cell, cytoplasm --> ER --> outside cell, Golgi --> ER --> outside cell, cytoplasm --> Golgi --> outside cell, nucleus --> cytoplasm, ER --> Golgi --> cytoplasm

Answers

Answer:

PFK (protein): cytoplasm only

Insulin (protein): ER->Golgi->outside cell

Why can't organisms in a population follow the exponential growth pattern for a long period of time

Answers

because, even if they sustain a steady birth and death rate, food is bound to grow somewhat shorter at a certain point, and it will decrease. but in the absence of eating as much, the food has a short booming growth rate as well, which raises the organisms growth rate again, and it sustains this cycle of ups and downs.  the same exact thing happens with its predators. another thing that can happen is a deadly disease, or a sudden heat wave or freezing period, or the finding of even more healthy food that create more production.

____ is a process by which organisms with characteristics suited to the environment will survive and reproduce. a. natural selection c. evolution b. artificial selection d. organic evolution

Answers

The correct answer is (a) Natural Selection

Natural Selection is the process by which the the phenotype which best suits the environment survives and reproduce. This is because of the differences in the phenotype. The species evolve through a period of time to adapt the environment. The adaptations or the characters are inherited to the next generation over the population. Natural selection acts on the phenotype and is the main key for evolution of species.

Specialized cells are formed when cells differentiate.
a. True
b. False?

Answers

Specialized cells are formed when cells differentiate - this is true. When you have stem cells, you're talking about undiferentiated cells with no specific roles in the body. When these cells start differentiating and assuming different roles, they are also becoming specialized.
