Answer:
In plants, minerals and water are transported through the xylem cells from the soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. Thus, there is continuous water movement into the xylem.
Bài giải:
Ở thực vật, các chất khoáng và nước được vận chuyển qua các tế bào xylem từ đất đến lá. Các tế bào xylem của thân, rễ và lá liên kết với nhau tạo thành một kênh dẫn đến tất cả các bộ phận của cây. Do đó, có sự chuyển động liên tục của nước vào xylem.

osmosis is the net movement of water through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration
what is osmosis ?Osmosis is defined as the passive process in which the molecules move from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane with out expenditure of external energy.
Gases and supercritical liquids are solvent undergo the process of osmosis; It can be up two types such as Endosmosis where a substance in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid by a process of deplasmolysis.
When a substance in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or undergoes plasmolysis. This is known as exosmosis.

Students created note cards comparing characteristics of eukaryotic and prokaryotic cells.
Which set of note cards most accurately compares these cells?
Given what we know about Eukaryotic and Prokaryotic cells, we can confirm that the note card labeled "F" is the one that best compares these two cell types.
Eukaryotic and Prokaryotic cells have many differences to discuss, the ones mentioned in note cards, however, are:
The presence of membranes surrounding organelleThe location of the DNA for each cellProkaryotic cells are cells that lack any organelle or nucleus. This is due to the absence of membranes, which are needed to maintain the structure of the organelle. Due to the lack of membranes and therefore of a nucleus, the DNA of these cells can be found floating in the cytoplasm. Table F is the only one that accurately represents these traits.
Eukaryotic cells, on the other hand, are those that do possess membranes. The presence of membranes allows the eukaryotic cells to have a nucleus that can contain their DNA. This cell type is that of most multicellular organisms, whist the prokaryotic are known most commonly as bacteria. Once again, table F is the one that best represents this data.

what was the path of darwin’s voyage
Answer:
In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship's naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos.
Explanation:
Most of the trip was spent sailing around South America. There Darwin spent considerable time ashore collecting plants and animals. Darwin filled notebooks with his observations of plants, animals, and geology. The trip was an almost five-year adventure and the ship returned to Falmouth, England, on October 2, 1836.
which process does not occur within a mitochondrion in a eukaryotic cell?
The process that does not occur within the mitochondria of a eukaryotic cell is glycolysis. I can conclude this because I believe you are referring to the options for this question which are:
A) Krebs cycle
B) Glycolysis
C) ATP synthesis
D) Electron transport chain
Glycolysis is a process in which glucose in the cytoplasm of a cell is broken down to produce energy in the form of ATP. The word glycolysis means "glucose splitting". It is one of the stages of cellular respiration. In fact, it is what begins this process.
Glycolysis is an anaerobic process meaning it does not need the presence of oxygen to function properly. Although this is a very important process and does participate in the creation of ATP, it does not occur in the mitochondria, but rather in the cytoplasm of a cell.

why do chloroplasts make energy carriers during the light reactions?
Answer:
consist of array of chlorophyll molecules. *** The absorb energy excited electrons to a higher energy level. ... *** As H+ diffuse through ATP synthase, down their concentration gradient, the enzyme uses the energy of the moving ions to ATP.
Explanation:
Chloroplasts make energy carriers such as NADPH in which the light energy is caught up. Together with carbon dioxide they are used to synthesis glucose during light reaction in photosynthesis.
What is light reaction in photosynthesis ?The first series of events that start the process of photosynthesis require light and are referred to as light reactions or light-dependent reactions since they depend on light as their energy source.
Light energizes the electrons in the chlorophyll molecule as it reaches the chloroplast. These electrons accelerate to higher energy levels because they have taken in or caught that energy and are now carrying it. Excited electrons have high energy. Who wouldn't be thrilled to have the capacity to sustain life?
Chlorophyll is left at a loss when the excited electrons depart to take part in other reactions; eventually, they need to be replaced. In order to break water molecules during that replacement process, an enzyme complex and light are both necessary. Hence, energy carriers plays a significant role in light reaction.

WHICH RESERVOIR OF THE CARBON CYCLE CHANGES THE MOST AND THE QUICKEST?
(please helpp)
the ocean is the reservoir that changes the most and the quickest
The reservoir of the carbon cycle that changes the most and the fastest is the atmosphere, as the atmospheric carbon pool changes due to the constant release of carbon dioxide through household sources and cellular respiration.
What is the significance of the carbon pool?The carbon pool maintains the carbon ratios in the earth, as the atmosphere is the reservoir of the carbon cycle that changes the most and quickest due to burning fossil fuels, usage of household electric appliances, usage of more vehicles that release carbon dioxide, deforestation, etc. If the carbon pool is not maintained and becomes uncontrolled, the environment will be harmed due to global warming, etc.
Hence, the reservoir of the carbon cycle that changes the most and the fastest is the atmosphere, as the atmospheric carbon pool changes due to the constant release of carbon dioxide through household sources and cellular respiration.

Which characteristic best supports that an offspring is produced by sexual reproduction and not asexual reproduction?
Answer:
The offspring has the same number of chromosomes as its mother and father.
Explanation:
The child shares the same number of chromosomes with both parents. Two parents participate in sexual reproduction, which results in children with distinct genetic makeup.
What is sexual reproduction?A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization.
Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent. Asexual reproduction allows for the rapid production of vast numbers of children by a single person.
This is due to the fact that in asexual reproduction, the only single parent produces an additional child that is genetically identical to the parent.
Therefore, the sexual mode of reproduction is seen to be superior to the asexual mode.

name three ways that you can explore specific genes to see if they would make good barcodes for species identification.
The barcode gene sequences should show less intraspecific gene variation than interspecific variation, contain conserved flanking regions and have a short length.
The three most important constraints to explore the suitability of a nucleotide sequence in order to be used as a DNA barcode for taxonomic identifications are:
Barcode gene sequences show less genetic variation within species (intraspecific variation) than between species (interspecific variation).Barcode sequences also show conserved flanking regions in order to be amplified in all species to be identified/categorized.Barcode sequences have short lengths due to technical constraints (amplification by PCR is ideal no more than 1000 base pairs).For example, in animals, an excellent barcode gene sequence used for taxonomic identification is the Cytochrome Oxidase I (COI) gene because this sequence can be used across the evolutionary spectrum.
