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.

Which of the following is believed to be common among all mass extinction events?(1 point)
a significant change in the global climate
the type of species that went extinct
the type of event that causes the extinction
the number of species that went extinct
Answer:
D the type of event that causes the extinction
The correct answer is a significant change in the global climate, as due to this is believed to be common among all mass extinction events.
Climate extrude interacts with threats which include habitat loss and overharvesting to similarly exacerbate species declines. The decline of species and ecosystems can then boost up weather extrude, growing a remarks loop that similarly exacerbates the situation.
What is global mass extinction?The mass extinction is an end result of human activity, pushed through populace boom and overconsumption of the earth's herbal resources. The 2019 international biodiversity evaluation through IPBES asserts that out of an expected eight million species, 1 million plant and animal species are presently threatened with extinction.
Therefore it is clear that a significant change in the global climate is believed to be common among all mass extinction events.

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.

Explanation:
How can you tell from a food web which organisms will have the greatest biomass?
Answer:
You can tell by which animals are at the top of the food chain.
Explanation:
You can tell this because if you count all the biomass below the animals at the top of the food web (which eat all the biomass below it), there is much more biomass below these animals (the ones at the top of the food chain), than any other animal below it. For example, if the rat ate a grasshopper it will receive its biomass, but if the python then eats the rat, then the python will be getting the biomass of the rat and the grasshopper, compared to the rat just getting the biomass of the grasshopper. So since there is much more biomass below the animals at the top of the food web, this means that the animals at the top of the food web receive the most biomass (when they eat the animals below them) out of the whole food web individuals.

Biochemistry involves the production and degradation of biological molecules such as nucleic acids, proteins, lipids, carbohydrates, and vitamins. Changes in the production or degradation of these important molecules can cause disorders and diseases in humans. For each of the human disorders and diseases listed below, indicate whether it is caused by a change in: (A) nucleic acids (for example: DNA or RNA); (B) amino acids/proteins; (C) lipids (for example: cholesterol or triglycerides); (D) carbohydrates/sugars; or (E) vitamins. Provide only one (1) answer for each disease.
Answer:
Disorders are present below.
Explanation:
Degradation of nucleic acids causes Lesch-Nyhan syndrome and mitochondrial depletion syndromes in human body, degradation of proteins causes phenylketonuria and tyrosinemia diseases in humans, degradation of lipids causes Gaucher disease and Tay-Sachs disease. Due to these diseases of lipids, we have not enough enzymes to break down lipids, degradation of carbohydrates leads to diabetic ketoacidosis, hyperosmolar coma and hypoglycemia, and degradation of vitamins causes anemia and scurvy diseases in the body.

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.

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.

This is because fertilizer or manure are formulated substance that contain different nutrients which when applied to the soil will add nutrients to the soil and make nutrients available for plants absorbing and these nutrients absorbed will help improve yield. They contain nutrients that help boost plants growth.
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.
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.
