Explanation:
Plant cells complete cell division differently than animal cells. Unlike animal cells, that use cleavage to create new cells, in plants a cell _____ grows between the newly forming nuclei creating _____ daughter cells. A cell _____ will then form there.
Unlike animal cells that use cleavage to create new cells, in plants, a cell PLATE grows between the newly forming nuclei creating TWO daughter cells.
A cell plate will then form the inside producing the rigid cell walls that separate the daughter's cells. The cell plate emerges by fusion of Golgi vesicles that coalesce at the equator to form a disk-like structure.These Golgi vesicles generate the Golgi body before the cell plate.In conclusion, unlike animal cells that use cleavage to create new cells, in plants, a cell PLATE grows between the newly forming nuclei creating TWO daughter cells.

a symporter is moving glucose and sodium levels are being depleted in extracellular fluids. what can be concluded about the movement of glucose? choose all that apply.
Two molecules are simultaneously and uniformly moved through a membrane by proteins known as symporters.
This mechanism's most widely accepted explanation involves molecules adhering to the exposed transport protein on the membrane's outside.
An antiporter is the Na+/K+ pump. It has places where Na+ and K+ ions can attach. The pump needs an energy source since these ions must travel against gradients in their concentration. As a result, it attaches to ATP and hydrolyzes it into ADP. Energy is consequently released.The pump changes its form using this energy. After the conformational change, the ions dissolve from the pump but are discharged in various directions. Na+ ions are pushed out of the cell as K+ ions are introduced into it.
The Na+/K+ pump plays a key role in maintaining the potential of cell membranes and transmitting nerve impulses. Without enough K+ ions, motor neurons' functionality may be compromised, which could cause the aim.

C. Hershey and Chase used radioactive phosphorus to follow the nucleotides in their experiment.
D. It was discovered by them that while different strains of bacteria have different percentages of nitrogen bases, the percent of adenine and the percent of thymine are equal as are the percentages of guanine and cytosine.
E. Hershey and Chase experiment lent strong credence to the idea that DNA is the hereditary material, at least of viruses.
The statement that is not true about the blender experiment is it was discovered by them that while different strains of bacteria have different percentages of nitrogen bases, the percent of adenine and the percent of thymine are equal as are the percentages of guanine and cytosine, option D is correct.
It was not discovered by Hershey and Chase in their experiment that the percentages of adenine and thymine are equal, as well as the percentages of guanine and cytosine. This discovery was actually made by Erwin Chargaff, who observed the base composition of DNA from various species and found that the amount of adenine is roughly equal to thymine, and the amount of guanine is roughly equal to cytosine.
Hershey and Chase's experiment, on the other hand, provided strong evidence for DNA being the hereditary material, specifically for viruses. They used radioactive phosphorus to label the DNA and radioactive sulfur to label the protein, showing that viral DNA, not protein, enters host cells during infection, option D is correct.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

Is mRNA read in translation?
The process of translating mRNA into the chain of amino acids occurs on ribosomes in the cytoplasm of the cell, where mRNA is read.
Polypeptide chains are produced from the amino terminus to the carboxy terminus of all mRNAs, which are read in the 5' to 3' direction. According to universal genetic code, the mRNA specifies each amino acid by three bases (a codon).
During translation, the second critical stage in gene expression, the mRNA "reads" the genetic code, which links the DNA sequence to the amino acid sequence in proteins. Each codon in mRNA denotes a particular amino acid, and each codon is a trio of nucleotides. As a result, the mRNA sequence serves as a template for the assembly of the chain of amino acids that constitutes a protein.

How do convection currents in the atmosphere form?
A Warming air expands, becomes denser, and sinks. As the air sinks, it displaces cooler, less dense air which rises
B Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down
C Cooling air contracts, becomes denser, and sinks. As the air sinks, it displaces warmer, more dense air which rises
D Cooling air contracts, becomes less dense, and rises. As the air rises, it pushes warmer, more dense air down
Answer:
B. Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down.
Explanation:
The options D and A can be eliminated because when a gas expands without gaining additional mass, it will become less dense; when a gas contracts without losing mass, it becomes more dense. Therefore, these two options conflict with the idea of density and cannot be true.
Option B is superior to Option C because convection currents are typically portrayed as beginning with the rise of warm air, which displaces/is replaced by cooler, dense air from the upper atmosphere. While Option C is similar, it describes the opposite series of events.
A student wants to investigate osmosis. A carrot was placed in a dilute solution.
a) What will happen to its mass?
b) The carrot was placed in 0.4 mol/dm 3 solution. Its mass did not change.
c) What does this tell us about the concentration of the carrot?
d) The carrot was placed in a concentrated solution. What will happen to its mass?
a) When a carrot is submerged in a diluted solution, water will osmosis into the carrot cells. As a result, the cells will become turgid and the carrot's mass will rise.
b) The carrot's inability to alter in mass when submerged in a 0.4 mol/dm3 solution shows that the solute concentration—which includes salts and sugars—within the carrot cells is also 0.4 mol/dm3. There is no net movement of water into or out of the cells at this concentration.
c) This indicates that the carrot and the 0.4 mol/dm3 solution have come to an equilibrium. At this concentration, the passage of water into and out of the cells is balanced, and there is no net gain or loss of water.
d) If the carrot is submerged in a concentrated solution, water will osmotically escape from the cells, plasmolyzing them. The mass of the carrot will shrink as a result.
OsmosisOsmosis is the transfer of water molecules from a region with a high concentration of water to a region with a low concentration of water through a membrane that is selectively permeable. Since a diluted solution contains more water molecules than carrot cells do, water will osmotically flow from the fluid into the cells. The carrot cells become turgid, which is another word for inflated and hard, as a result of this water inflow. The carrot's mass so grows as a result.The carrot's inertness in a 0.4 mol/dm3 solution shows that the solute concentration inside the cells of the carrot is also 0.4 mol/dm3. At this concentration, there is no net gain or loss of water since the flow of water into and out of the cells is balanced. This is due to the fact that the solute concentration in the carrot cells and the solution are the same. Isotonic describes this condition.learn more about osmosis here

Analyse how plastics has become one of the major contributors to this problem?
Plastics have become one of the major contributors to environmental problems due to their widespread use and improper disposal. Plastics are synthetic polymers derived from petrochemicals, and their production has increased exponentially over the past few decades. This increased production, combined with the durability and resistance of plastics to natural degradation, has led to their accumulation in the environment.
Plastics contribute to environmental issues in several ways. First, their production involves the extraction of fossil fuels and the release of greenhouse gases, contributing to climate change.
Additionally, plastics are often used for single-use purposes, such as packaging and disposable products, leading to a significant amount of waste generation.
Improper disposal of plastics, such as littering or inadequate recycling, results in plastic waste entering water bodies, soil, and ecosystems.
Plastic pollution poses various hazards to wildlife and ecosystems. Marine animals, such as seabirds, turtles, and marine mammals, can ingest or become entangled in plastic debris, leading to injury or death.
Plastics also break down into smaller fragments called microplastics, which can be consumed by marine organisms and enter the food chain, potentially impacting human health.
To address the plastic pollution problem, initiatives focusing on reducing plastic consumption, promoting recycling and waste management, and developing sustainable alternatives to plastic are crucial.

you observe a cow that is giving birth. you notice that the back feet are coming first. what is a major concern that you for the safe delivery of the calf.
When the back feet of a calf are coming first during the birthing process in a cow, a major concern is the risk of dystocia or difficult labor. This presentation is known as "breech birth" or "posterior presentation."
The normal presentation for a calf during birth is with the front feet and head coming first, as they are better suited to navigate through the birth canal. When the back feet are coming first, it can indicate that the calf is in an abnormal position within the birth canal.
The major concern with a breech birth is that the calf's body is larger and less flexible than its head, making it challenging for the cow to deliver the calf naturally. This can result in a prolonged or obstructed labor, increasing the risk of injury to both the cow and the calf.
In such cases, it is crucial to seek veterinary assistance promptly to ensure a safe delivery. The veterinarian can assess the situation, provide necessary interventions such as repositioning the calf or performing a cesarean section if required, and help minimize potential complications.
To ensure the well-being of the cow and calf during calving, it is always recommended to have a trained professional, such as a veterinarian or experienced livestock handler, present to assist and monitor the birthing process.
