Can variation be advantageous to the survival of a lima bean population during times of a
changing environment?
Answer:
The correct answer is - yes, variation can be advantageous.
Explanation:
The population of the lima beans that are able to adapt to changes and include these variations in their population will lead individuals are able to survive and reproduce to increase their numbers in changing environments. The igher the variability in the population is, the higher the chances of the to be advantageous for their survival and increase their population.
Thus, the correct answer is - yes.

How does cell division differ in prokaryotes and eukaryotes? And how are they similar?
Different:
Prokaryotes are single cell organisms, including bacteria, which divides through binary fission where the daughter cell is a complete replica of the father cell. Eukaryotes are multi-cell organism, which reproduce either through mitosis or meoisis. Meoisis is sexual reproduction while mitosis is asexual reproduction
Similar:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
Prokaryotes divide by binary fission, while eukaryotes undergo mitosis or meiosis. Both processes involve replicating DNA and cytokinesis.
Prokaryotes and eukaryotes differ in cell division processes and complexity. Bacteria divide by binary fission. The cell membrane pinches inward to divide the cytoplasm into two daughter cells in binary fission. Mitosis or meiosis divide eukaryotes. Mitosis divides a cell into two identical daughter cells. DNA replication, chromosome alignment, and cytoplasm division are involved.
Sexually reproducing creatures undergo meiosis, a specialised cell division. Two rounds of division produce cells with half the chromosomes needed for sexual reproduction. Despite these variations, prokaryotic and eukaryotic cell division involves DNA replication and cytoplasm division to form daughter cells. Organisms grow, develop, and reproduce through these mechanisms.

7 Identify- By what process did these cells form?
Answer:
Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Explanation:
Hope this helps
Cells can form through a process called cell division.
What is cell division?In cell division, a single cell divides into two or more daughter cells. This is the primary way in which living organisms grow and develop, as well as repair damaged tissues and replace old or dying cells. Cell division can occur through two main processes: mitosis and meiosis.
Mitosis is a type of cell division that results in two identical daughter cells, while meiosis is a type of cell division that produces four genetically diverse daughter cells, typically used in the production of gametes for sexual reproduction. Other processes, such as differentiation, also play a role in how cells form and develop into specialized types of cells with distinct structures and functions.

Certain seed-eating birds are able to crack seeds according to the size of their beaks. Long beaks are able to crack larger seeds, whereas shorter beaks are able to crack smaller seeds. A graph of a bird population with different-sized beaks is shown below.
After a several-year drought, smaller seeds became scarce, but drought-resistant trees continued producing larger seeds. What graph would best predict the change in beak length of the bird population?
Answer:
its the last one
Explanation:
because it was good then bad after drought
The graph that would best predicts the change in the break length of the bird population is that of the third graph.
How are the beaks of the seed-eating birds developed?The seed-eating birds includes the Sparrows and finches, and redpolls. Grouse has different sizes of beaks as per the body ratio. Evolution and natural selection play a crucial role in the development of the beaks. The shape of the break determines the type and shape of seed it will eat.
As per the graph given the length of beaks will increase as the number of individual birds increases. Thus the diversity of breaks depends on the diversity of the species. Hence the option C is correct.

The scenario which describes a relationship of parasitism is a tick feeds on the blood of a dog. Therefore, the correct option is D.
What is parasitism?In parasitism, one organism (the parasite) benefits at the expense of another organism (the host). In this scenario, the tick benefits by feeding on the dog's blood, while the dog is harmed by the loss of blood and potential transmission of diseases by the tick.
Option A describes a mutualistic relationship, where the ox pecker birds benefit by feeding on the ticks, and the zebras benefit from having the ticks removed.
Option B describes a predator-prey relationship, where the polar bear benefits by catching and eating the seal, while the seal is harmed by being eaten. Option C and D describe commensalism. They both are same. Therefore, the correct option is D.

Most water molecular move from x to y decreasing the concentration gradient of sucrose. The solution will always move down the concentration gradient.
This means the water always move from this is more water to where there is less water.
Therefore, water will move from a hypotonic solution to the hypertonic solution.

Why is a cell membrane important to both plant and animal cells?
Cell membrane is a selectively permeable barrier, an outer covering of both plant and animal cell. It protect the cell from external harsh environment.
What is cell membrane?Cell membrane has two major components such as Proteins and lipids where as the ratio of protein to lipid in cell membrane may vary depending on types of cells.
The most common lipid is phospholipid, which form a semi-permeable lipid bilayer.
Some organelles in a cell are also have its own cell membrane such as nucleus and mitochondria.
The function of cell membrane is to maintain integrity of the internal environment of the cell, act as a base of attachment for the cytoskeleton in some organisms resulted in support cell and maintain its shape.
It helps in transport of nutrients into the cell and transport of toxic substances out of the cell due to its selectively permeable nature.
