Which most likely contributes to the curving pattern of global winds?
Answer:
The correct answer is - B. Coriolis effect.
Explanation:
In the Northern Hemisphere winds appear to curve to the right as they move whereas, in the southern hemisphere, it looks as all the winds curve to the left.
This is known as the Coriolis effect, which occurs due to the rotation of the earth. The Coriolis Effect causes the movement of air to travel to long distances around the Earth to curve pattern.

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.

1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.

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.
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.

of seeds. She filled two plant pots of the same size with equal amounts of
soil.
Pot 1 was labelled 'LIGHT and Pot 2 'DARK'. Five lettuce seeds were planted
in each of the pots. Both plants were given sufficient water.
Pot 1 was put in direct sunlight. A cardboard box was placed over Pot 2
and no light was allowed to enter.
21.1
Write down a hypothesis for the investigation.
Pleas

Answer:
The correct hypothesis would be -
"if the light is required for seed germination of seed, then in the absence of light lettuce seed will not germinate"
Explanation:
The hypothesis is always based on a question one wanted to answer. The hypothesis is the possible explanation of a world natural problem. One needs to make his hypothesis on the basis of the research he made.
To test the hypothesis one needs to develop an experiment like here formed an experiment to test if the light is required for the germination of seeds. Thus, hypothesis would be "if the light is required for seed germination of seed, then in the absence of light lettuce seed will not germinate"
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.

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.
g Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of _______.
Answer:
This question lacks options, options are: A. Allopolyploid speciation B. Behavioral isolation C. Allopatric speciation D. Sympatric speciation E. Adaptive radiation. The correct answer is D.
Explanation:
Sympatric speciation consists of different populations of the same species, occupying the same territory, diversifying due to the appearance of isolation mechanisms that fulfill the same function as geographical barriers (a river, a mountain or a separation of tectonic plates, for example) that makes contact between both populations impossible. Sympatric speciation is a bit more difficult to understand, since a tangible and observable barrier appears in the first instance that makes contact between individuals of the same species and population impossible. In sympatric speciation there may be alleles for a gene that encode more or less successful behaviors in the face of certain events. As this genetic information is heritable from parents to children and, under certain conditions, it can be expected that A2 species end up presenting sufficient behavioral differentiation with respect to A1 to give rise to different species after a long period of time. Both populations will end up exploiting different niches and accumulating very diverse adaptations, giving rise to two different species.
The example shown in the illustration is that of sympatric speciation.
Speciation is generally defined as a biological process that leads to the emergence of new species of organisms in ecosystems.
Speciation can be of 2 types:
Allopatric speciationSympatric speciationIn allopatric speciation, a new species emerge from ancestral species as a result of geographical separation. Thus, genetic flow from the ancestral species and the new species cease to exist.
In sympatric speciation, a new species emerge from ancestral species without any form of geographical barriers between them. Thus, both new and ancestral species coexist in the ecosystem.
In the illustration, a new species emerged from the population of sunflowers and coexist with the ancestral species of the same plant without interbreeding. This ticks all the boxes of sympatric speciation.

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.
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.
while looking at a graph, you notice a period of time where the line is perfectly horizontal what is most likely taking place during this time period
Answer:
The correct answer would be - the y-axis variable is constant.
Explanation:
In a normal line graph, there are generally two variables on two different axis one is at the x-axis and the other is on the y-axis that represents the correlation between these two variables. If there is a change in the variable present on the x-axis the change on the variable on the y-axis establishes the relationship among these variables.
If there is a period on the graph where the line is completely horizontal it means the variable present on Y-axis has no change during this period or is constant. Suppose a graph is plotted between speed or velocity on the Y-axis. A perfectly horizontal line on this graph means that speed is not changing over time and remain at te same speed.
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.
