Answer: taste buds are decreasing in number and sensitivity
Explanation:
The grandmother complains that the meal she just ate was rather bland or tasteless because as an elderly person, her taste buds will gradually reduce and this will reduce the are sensitivity of her tongue.
Other factors that can also result in loss of taste include smoking. As one grows older, the taste bud reduces and even the remaining one starts to shrink. After one reaches 60, the sensitivity to the tastes that we've begin to shrink. Also, when one grows older, less saliva is produced by the tongue and one can also have dey mouth as they grow older.

Mitosis is the process through which a cell replicates its DNA and produces two identical daughter cells. If a cell undergoing mitosis is currently in anaphase as shown in the diagram below,
The duplicated genetic information found in a parent cell's nucleus is divided into two identical daughter cells during the fourth stage of mitosis, referred to as anaphase. Thus, option B is correct.
What mitosis process through which cell replicates its DNA?The sister chromatids are able to separate because the protein “glue” holding them together is degraded. Each chromosome now exists on its own. The opposing ends of the cell are drawn to the chromosomal pairs in each pair.
The replication fork is connected to a number of proteins that aid in the The way DNA polymerase creates new strands is mostly by include nucleotides that complete each (template) strand. The S-stage of interphase is when DNA replication happens.
Therefore, Sister chromatids split from one another and are drawn to the opposite ends of the cell during anaphase.

You have identified a new, recessively inherited trait in dogs: floppy ears. To determine if the gene for Floppy Ears is X-linked or not, you should:
Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.
Read this passage about CFTR mutations. Then, using your knowledge of cells, select the section that describes mutations that occur at the ribosome.
The CFTR gene was first discovered in 1989, but as with many research endeavors, that was only the first step. Since that first discovery, scientists have identified 1,700 mutations of the CFTR gene. These various mutations are classified according to their specific effect on the CFTR protein. Some mutations interfere with the protein assembly process. These are called protein production mutations and result in construction of incomplete or unstable proteins. Once built, the CFTR protein folds itself into a stable three-dimensional tube shape and travels to the cell membrane where it inserts itself as a channel between the cell’s interior and its surface. Mutations that affect this part of the process are called protein processing mutations. Each channel has a gate that opens and closes in response to chemical signals. Gating mutations cause misinterpretation of those chemical signals. Conduction mutations change the inside of the tunnel, making passage through the channel slower and more difficult.

When a cell gains water, what happens to its size and weight
Answer: Water will move across the semi-permeable membrane in order to balance both sides until they are neutral.
"Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permeable membrane is one that allows unrestricted passage of water, but not solute molecules or ions."
Or
When a cell gains water it becomes much bigger and heavier which could possibly lead to its explosion.
"Water moving into a cell can make the cell swell, or even burst! This happens when cells are placed into a hypotonic solution. Like the egg in distilled (pure) water. Water leaving a cell can make it shrivel up"
Answer:
When a cell gains water, the size will expand, making the cell bigger, and the weight will increase, depending on the type of cell as well as the amount of water.

Patches of fibrocartilage formed in the healing of a fracture are called __________, whereas the bony collar formed around the fracture is called __________.
Answer:
Patches of fibrocartilage formed in the healing of a fracture are called soft callus, whereas the bony collar formed around the fracture is called hard callus.
Explanation:
In the fibrocartilage or soft bone callus phase, the necrotic bone is removed by osteoclastia and dead soft tissues are being removed by macrophages. The fibroblasts are activated and a granulation tissue is generated that supposes the appearance of new vessels and, with them, the arrival of more connective tissue cells. A tissue called fibrous callus or fibrocartilage begins to form, composed of a poorly structured amalgam of fibrous tissue, cartilage, and amorphous bone.In hard callus, bone and later cartilage are deposited in the growing historical mass. The two collars of callus, fixed to the bone at some distance from the fracture, they grow upwards and towards each other, forming an arc on focus.
Strong contrasts in texture have what effect on a monochromatic design?
Answer:
It prevents monotony
Explanation:
Strong contrasts in texture have a primary effect on monochromatic design by ensuring it’s more eye catching and not too plain.
Contrasts is a term used to describe the display of an objects dissimilar sides. A monochromatic light is known to have just one color and the strong contrasting texture however makes it possible for it to have different color differences thereby preventing monotony.
Unlike many plants, the stomata of the water lilies are found on the upper surface of the leaves. Suggest a possible reason for this adaptation.
Answer:
All plants need stomata on the surfaces of their leaves for photosynthesis. ... The stomata of water lilies are on the upper surface of their leaves, maximizing air exposure. Stomata on the underside of the leaves would be wasteful because water contact interferes with the exchange of carbon dioxide and oxygen.
mark me brainliestt :))
Answer:
Because the upper surface of the water lillies are not immersed in water.
Explanation:
Since the stomata is an opening for water to be excreted, the water lillies (which are usually found in water) need a surface which is not in contact with water so as the release the water as a metabolic waste. And since the lower surface of the water lilly's surface is immersed in water, there will be no point to excrete the water.
3 Sea turtles lay around 100 eggs because only a few will hatch and survive to adulthood. Which of Darwin's 4
principles of natural selection is this an example of?
Inheritance
Adaptation
Differential survival and reproduction
Variation
Answer:
Differential Survival and Reproduction.
Explanation:
Differential survival is when organisms of the same species must compete for what they want. Only some organisms survive to adulthood. Differential survival is important in evolution because the best-fitted animals get to reproduce and pass down their adaptations to the next generation.
Darwinism, Charles Darwin's theory of the evolution proposed as an explanation for organic change. It refers to Darwin's specific belief that evolution is primarily driven by natural selection. As here, 3 sea turtles lay around 100 eggs can comes under the principle of differential survival and reproduction, i.e., option C.
What is Darwin's principles?Darwin developed a concept that evolution is specifically caused by the interaction of three principles.
Those principles are:
Variation: a changing factor present in all forms of life that Darwin did not attempt to explain.Heredity: the conservative force that passes on similar organic forms from generation to generation.Struggle for existence: which determines which variations will confer advantages in a given environment, thereby changing species through a selective reproductive rate.As in the given scenario, 3 Sea turtles laying around 100 eggs because only a few will hatch and survive to adulthood represents the principle of differential survival and reproduction.
Thus, the correct option is C.

What genetic and other changes might have caused these cells to escape normal cell cycle regulation these cells are hela cancer cells
Answer:
Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle
Explanation:
The term cell cycle refers to the mechanism of DNA replication and cell division, which involves a series of sequential steps. The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events. HeLa is an immortalized cell line derived from cervical cancer cells. These cells (HeLa) contain 76 to 80 total chromosomes (instead of the 46 chromosomes that contain normal-diploid body cells), some of which are heavily mutated. These mutations can affect CDKs that control the cell cycle as well as checkpoint-control mechanisms (for example, those resulting from DNA damage), thereby cells do not enter programmed cell death (apoptosis) and proliferate uncontrollably.

Bony Fish (bass etc.) and marine mammals (like dolphins) evolved some similar adaptations for survival in aquatic environments. However, they evolved separately and are not closely related evolutionarily. What type of evolution does this represent?
Answer:
Convergent evolution
Explanation:
Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.
