The tiny holes in the cell walls of plants that allow for the passing of materials are called the _____. middle lamella
plasmodesmata
stomata
stroma

Answers

Answer 1
Answer: The tiny holes in the cell walls of plants that allow for the passing of materials are called the plasmodesmata. The correct option among the different options given in the question is the second option. Plasmodesmata are actually very small or rather microscopic channels that traverse the cell walls of the plant cells.
Answer 2
Answer:

Answer: The correct answer for the blank is-

Plasmodesmata.

Plasmodesmata can be described as small channels ( or small holes) in the cell wall of adjacent plant and algal cell.

These channels allow the cytoplasm of adjacent cell to physically communicate with each other, thus allows the transport certain molecules ( such as proteins) from one cell to the adjacent cell through a symplastic pathway ( that is through the cytoplasm of the cells).

Biochemical analysis uses similarities in __________ as evidence for evolutionary relationships

Answers

DNA sequence

Biochemical analysis will use DNA sequences to understand, contrast and explain a certain point of an evolutionary process. DNA sequence are analysed by the structure of the chromosomes. Chromosomes are helpful to describe both the person and the ancestral history of the specific individual. 

DNA sequences. Biochemical analysis looks at DNA, and also at proteins.

Energy is released to be used by a cell when a phosphate group isremoved from ADP to form ATP
added to ADP to form ATP
removed from ATP to form ADP
added to ATP to form ADP

Answers

Answer:

Energy is released to be used by a cell when a phosphate group is removed from ATP to form ADP.

Explanation:

Hello,

Adenosine diphosphate (ADP) is an important organic compound with a chemical formula C₁₀H₁₅N₅O₁₀P₂. It helps in metabolic activities and facilitates energy flow in living cells. The adenine in ADP combines with sugar molecules to form adenosine that can accept a phosphate group, upto 3 of them.

ATP is adenosine 5' triphosphate. This molecule is primary energy carrier in living organisms as it stores and transfer energy to living cells.Those in living things, both ATP and ADP store and release energy, more energy is in ATP than ADP.

During hydrolysis, a phosphate group is removed through the breakdown of high-energy bonds called phosphoanhydride bonds and energy is given out as ATP coverts to ADP.

So, the correct answer is the third option.

Answer:

The correct answer is the c = removed from ATP to form ADP

Explanation:

Hello ! Let's solve this!

It is a catabolic process where energy is released and formed from a complex molecule, simpler molecules. In this case, to release energy, ATP (adenosine triphosphate) removes a phosphate group to form ADP (adenosine diphosphate).

The correct answer is the c = removed from ATP to form ADP

What is a possible benefit of regulating the process of cell differentiation?A)
identifying genetic disorders
B)
determining the sex of an unborn child
C)
development of organs for transplantation
D)
studying the chromosomal changes during cell division

Answers

Answer:

The correct answer would be C)  development of organs for transplantation.

Cell differentiation refers to a process by which a cell becomes specialized to perform a specific function. For example, a liver cell, blood cell, muscle cell et cetera.

In multi-cellular organisms, life starts with a single cell (zygote) which then divide and differentiate into various types of cells. The specialized cells synchronize to form tissue which then form a particular organ.

Thus, regulation of cell differentiation can lead to development of specific organ which can be used for transplantation.

Answer: C) development of organs for transplantation

Explanation: Stem cells are human cells that can develop into many different types of cells. Stem cell research includes regulating the process of cell differentiation and stem cells can be used in the development of organs.
