why is active transport needed to take mineral ions into the cytoplasm of the root hair cell?
Answer: In plants, they need to move mineral ions from the soil into the roots. Mineral ions are more concentrated in the cytoplasm of plant cells than in soil water or dillute.
Explanation:
Minerals cannot be soaked up through osmosis since it only involves the movement of water. Because the minerals are in such low concentration, they cannot be absorbed through diffusion. Active transportation is used instead.
What is active transport?Active transport refers to the transport of molecules or ions into or out of a cell via the cell membrane, from a low concentration region to a high concentration region.
The particles use the energy released during respiration to move against the concentration gradient.
Active transport is defined as the movement of molecules against a gradient from a region of lower concentration to a region of higher concentration.
Active transport in plant root hairs allows plants to absorb mineral ions, which are required for healthy growth, even though the concentration of minerals in the soil is usually lower than in the root hair.
Thus, active transport is needed to take mineral ions into the cytoplasm of the root hair cell, as there is a need to move the minerals from the region of lower to higher concentration.

Where do chromosomal mutations begin?
Why do chromosomal mutations occur?
Answer:
A chromosome mutation is an unpredictable change that occurs in a chromosome. These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc.).
Explanation:
Brainliest please?
Answer:
1) Different types of chromosome mutations can originate in the germinal cells.
2) Chromosome mutations are alterations occurring in chromosomes that typically result from errors during nuclear division or from mutagens. ... Abnormal chromosome numbers result from nondisjunction, or the failure of chromosomes to separate correctly during cell division.

Question #4
Bacteria called thermophiles have been discovered that can live in natural hot springs unlike most
bacteria that cannot survive extreme heat. Using genetic engineering techniques, the heat resistant gene
in these thermophiles has been isolated and then inserted into wheat and corn cells in an attempt to
develop crops that can withstand global warming.
Which statement suggests a possible reason for inserting the thermophilic gene into the crops?
A
The wheat and corn now have increased tolerance to increased salinity levels, so the enzymes
inside their cells will not be denatured by salt allowing them to survive as the sea level rises.
B
The wheat and corn now have increased tolerance to heat, so the enzymes inside their cells will not
be denatured by extreme heat, allowing them to survive the increase in global temperatures.
С
The wheat and corn now have increased tolerance to cold, so the enzymes inside their cells will not
be denatured by extreme cold allowing them to grow in the Antarctic and Arctic regions.
D
The wheat and corn now have increased tolerance to a lower pH, so the enzymes inside their cells
will not be denatured by changing pH due to increased global temperatures allowing them to
survive
Nuaction #5
Answer:
D
Explanation:
A genetically modified organism (GMO) is any organism whose genetic material (DNA) has been modified by genetic engineering. In agriculture, GMO plants with resistance to abiotic and biotic factors have been developed.
The statement "the wheat and corn now have increased tolerance to heat, so the enzymes inside their cells will not be denatured by extreme heat, allowing them to survive the increase in global temperatures" suggests a possible reason for inserting the thermophilic gene into the crops (Option B).For example, Bt crops are GMOs capable of synthesizing proteins that are selectively toxic to insect pests but are innocuous to humans and animals. These GMO crops (Bt crops) were developed by inserting certain genes from Bacillus thuringiensis (Bt) bacteria into corn and cotton.Some genetic engineering techniques used for inserting genes and thus develop GMOs include the use of viral vectors, microprojectile bombardment, electroporation. microinjection, etc.In conclusion, the statement "the wheat and corn now have increased tolerance to heat, so the enzymes inside their cells will not be denatured by extreme heat, allowing them to survive the increase in global temperatures" suggests a possible reason for inserting the thermophilic gene into the crops (Option B).

Would you expect the entire crop grown from your preferred stalk to show the characteristics of the parent crop? Explain your answer.
Answer:
Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.

Answer:
Brownstead- Lowry base
Explanation:
A Brownstead- Lowry base accepts protons. If we look at this reaction, the water molecule accepted a proton to form its conjugate acid H3O^+.
Hence, in this particular instance, water behaved as a Brownstead- Lowry base in accordance with the definition of a Brownstead- Lowry bases.
Answer:
the correct answer is:
Explanation:
Water behaves as a base in this reaction.
The Bronsted-Lowry definition is applied because the reaction involves the transfer of H+ from one reactant to the other.
A Bronsted-Lowry base is defined as a substance that accepts a proton.
Because water gains a proton to form H3O+ in this particular reaction, it acts as a base.

How does DNA polymerase move along each strand of DNA?
A. Both move towards the replication fork
B. Both move away from the replication fork
C. One moves towards from the replication fork and the other moves away from it
D. There is only one DNA polymerase on the DNA at a time
Answer:
c i think
Explanation:
Answer:
B
Explanation:
This sort of replication, since it involves one nucleotide being placed right after another in a series, is called continuous. Whereas the DNA polymerase on the leading strand can simply follow the replication fork, because DNA polymerase must move in the 5' to 3' direction, on the lagging strand the enzyme must move away from the fork.
