As a plant grows, new root hair cells are formed from unspecialised cells.
How does an unspecialised cell become a new root hair cell?
Answer:
Root hairs appear in the root maturation zone and differentiate from unspecialised cells called trichoblasts.
Explanation:
Root hair arises as a small protrusion surrounded by a cell wall, they are found in the piliferous area; they can originate in unspecialised epidermal cells, in some called trichoblasts. The bump begins to elongate and moves away from the epidermis, forming root hair. The root hairs as they lengthen, it is seen that their content shows a polarized distribution, the apical part is constituted mainly by vesicles secreted by the Golgi apparatus that contain the precursors of the cell wall that are to be released by exocytosis. Trichoblasts can be arranged in different ways, there are roots where any of the cells that are part of the rhizodermis can give rise to a root hair. In other roots, trichoblasts and atricoblasts have been seen to be distinguished alternately along a row of cells.

PLEASE HELP///3. Heather had a color blindness test, and she was surprised to discover she suffered from red-green colorblindness. She told her biology teacher, who said, “Your father is color-blind too, right?” How did her teacher know this? Why did her teacher not say the same thing to the color-blind males in the class?
Answer:
In order for a woman to have the colorblind trait, they need to be X^cX^c, meaning that they have to get the trait from both their parents. Males can either have X^cY or X^CY and since Heather has it, it is definitive that her father had X^cY, which means that he is colorblind. Males in her class, on the other hand, can get it from either their mother or father.

What is the main factor that causes bedrock to weather at different rates?
1. Elevation above sea level
2. Mineral composition
3. Age of rock layers
4. Environmental factors
Answer:
2. Mineral composition
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Minerals is any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Hence, mineral composition is the main factor that causes bedrock to weather at different rates.
What are the possible results of speciation?
Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.

1. If an animal cell is placed into a solution whose concentration of dissolved substances is
higher than that inside the cell(osmosis). What will happen?
Answer:
Water will move out of the cell causing it to eventually shrink.
Explanation:
The tonicity of solutions determine the direction of water movement. Hypertonic solution is a solution whose concentration is higher than that of its external solution while hypotonic solution is a solution whose concentration is lower than that of its external solution. In this case, an animal cell is placed into a solution whose concentration of dissolved substances is higher than that inside the cell.
This means that the extracellular solution is HYPERTONIC to the cell's solution. Based on OSMOSIS, which is the movement of water from a region of lower solute concentration (high water conc.) to a region of higher solute concentration (low water conc.) via a semipermeable membrane, water will move out of the animal cell into the extracellular solution via the cell membrane (semipermeable membrane).
This movement of water out of the cell will eventually cause it to shrink and die.

What is the equation for calculating the change in water potential? In other words, this equation allows you to determine which way the water will move in response to two different concentrations.
Answer:
The correct answer is - Ψ = ΨS + ΨP.
Explanation:
The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).
Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.
Ψ = ΨS + ΨP.

How do enzymes reduce the amount of activation energy needed to make a chemical reaction go?
Answer:
Enzymes reduce the amount of activation energy needed by breaking substrate molecules
Explanation:
Enzymes break down substrate molecules to lower the amount of activation energy required.
What is activation energy?The least amount of energy necessary to bring atoms or molecules into a state where they may cause chemical transformation or physical transport is known as the activation energy in chemistry.
The differential of energy content between atoms or molecules in an active or transition-state configuration and the same atoms and molecules in their original configuration is known as the activation energy in transition-state theory. In mathematical formulas for values like the reaction rate constant, the activation energy is typically denoted by the symbol Ea.
Experimental rate constants or diffusion coefficients that are determined at various temperatures are used to calculate activation energies.
Therefore, Enzymes break down substrate molecules to lower the amount of activation energy required.

How organisms get ATP out of the food they eat
Why does the body respond to stimuli
Answer:
That is because of Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Hope this helped
All the best !!
The body typically responds to stimuli because of the function of the receptors.
How does the body of an organism respond to stimuli?The organism significantly responds to the stimuli by means of a number of effectors, such as muscles and glands. Energy is generally used in the process in order to facilitate an ideal function of the entire body and maintain homeostasis.
Due to this, the organisms change their behavior in response to changes in the surrounding environment. For example, an organism may move in response to its environment.
The process of responding to stimuli is generally mediated by the receptors which are the groups of specialized cells within the body. These receptors alter their physiology and function with respect to the surrounding environment and detect a change. In the nervous system, this directs to an electrical impulse being made in response to the stimulus through a chemical process.
Therefore, the body typically responds to stimuli because of the function of the receptors.

Explanation:
In prokaryotes, transcription and translation can happen simultaneously because
a. DNA and mitochondria are both located in the nucleus
b. DNA and ribosomes are both located in the nucleus
c. DNA and mitochondria are both located in the cytoplasm
d. DNA and ribosomes are both located in the cytoplasm
In prokaryotes, transcription and translation can happen simultaneously because DNA and ribosomes are both located in the nucleus. Therefore, option B is correct.
The ribosomes are responsible for protein synthesis. They are also found in the cytoplasm of prokaryotic cells. The ribosomes read the mRNA produced during transcription and directly synthesize proteins using the information encoded in the mRNA.
The absence of a nuclear membrane in prokaryotes allows for the coupling of transcription and translation to occur in close proximity in the cytoplasm.
