A daughter cell that matures to the inside of the vascular cambium becomes ______, and a daughter cell that matures to the outside of the vascular cambium becomes ______.
A daughter cell that matures to the inside of the vascular cambium becomes secondary xylem and a daughter cell that matures to the outside of the vascular cambium becomes secondary phloem.
The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops. As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root. A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.learn more about vascular cambium here: https://brainly.com/question/859907

A daughter cell that matures to the inside of the vascular cambium becomes secondary xylem and a daughter cell that matures to the outside of the vascular cambium becomes secondary phloem.
What vascular cambium is?The primary meristem in the stem is the vascular cambium, which produces undifferentiated wood cells on the inside and bark cells on the outside. When the vascular cambium is most active, its thickness ranges from around six cells during periods of dormancy to about 14 cells.
How is energy produced by the vascular cambium?Growing inward from the vascular cambium, the xylem is the vascular tissue responsible for carrying water and nutrients throughout the plant. The vascular cambium, which produces phloem, expands outward to carry big molecules like sugar. Additional xylem and phloem cells are produced by the vascular cambium cells during division.

What evidence suggests that proteins are synthesized and modified in the rough er as opposed to the smooth er?
The presence of ribosomes on the rough ER suggests that the proteins are synthesized as well as modified there as opposed to the smooth ER.
Ribosomes are responsible for the synthesis of proteins from the amino acids. They translate each codon on the RNA template and match it with the appropriate amino acid to make a protein. This process is known as translation. Ribosomes can be found free in the cytosol or attached to the surface of the endoplasmic reticulum. When the ribosomes are bound to it, it is known as the rough ER and without it, it is called smooth ER. Smooth ER performs different functions like the synthesis of lipids and phospholipids. Since it does not have ribosomes, it cannot synthesize proteins.

Fish in a marine environment must maintain a relatively constant ion concentration in their tissues and blood. How do the chloride cells in the gills aid fish in the removal of excess ions?
The chloride cells actively remove ions from the body and water follows by osmosis.
The chloride cells create a countercurrent system where ions are lost from the body and water is absorbed to dilute other ions (NaCl). Marine fishes can excrete salt by clusters of special cells (chloride cells) in the gills.
In euryhaline bony fish, gills usually secrete extra chlorine to maintain a constant plasma chlorine concentration in environments of different salinity. Fishes are exposed to major osmotic challenges in freshwater and marine environments.
Osmosis is the diffusion of water across a membrane in response to osmotic pressure caused by an imbalance of molecules on either side of the membrane.

Which can serve as substrates for atp production?
Answer:
A molecule containing readily 'detachable' phosphate group, an inorganic phosphate, and ADP.
Explanation:
For substrate-level phosphorylation, take glycolysis as an example. Phosphoenolpyruvate has a readily 'detachable phosphate', which with the help of Pyruvate Kinase, is able to be 'attached' to ADP. Both Phosphoenolpyruvate and ADP act as substrates.
For oxidative phosphorylation, take ATP synthase as an example. Due to the proton motive force, the 'motor' of the enzyme allows the knob to spin, changing affinities for ADP, Pi (inorganic phosphate), and ATP. Thus, to produce ATP, ADP and Pi are required as substrates.
In all, a molecule containing readily 'detachable' phosphate group, an inorganic phosphate, and ADP can serve as substrates for ATP production.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enzyme important for efficiency in pcr?.
The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.
Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second. It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.

Loss of dna sequences at the ends of chromosomes in the ________ region may cause cell senescence.
Loss of DNA sequences at the ends of chromosomes in the telomere region may cause cell senescence.
A chromosome's end contains a stretch of repeating DNA sequences known as a telomere. Chromosome ends are shielded from fraying or tangling by telomeres. The telomeres get a little bit shorter every time a cell divides. They eventually get so short that the cell can no longer successfully divide, and the cell then perishes.With age, telomere length decreases. The health and lifespan of an individual are impacted by the progressive shortening of telomeres, which causes senescence, apoptosis, or oncogenic transformation of somatic cells.
