A. A sound wave
O B. A wave carried through a rope
O c. A light wave
OD. A wave on top of water
Answers
A wave carried through a rope is an example of longitudinal wave.
What do you mean by longitudinal waves?Longitudinal waves are waves in which the vibration of the medium is parallel to the direction the wave travels and displacement of the medium is in the same direction of the wave propagation.
The wavelength of a longitudinal wave is defined as the distance between two successive compressions or rarefactions. As given, the distance between the 5th and 6th rarefaction is 25 cm, therefore the wavelength of the wave will be 25 cm.
A sound wave is an example of a longitudinal wave and is produced by the vibrating motion of the particles that travel through a conductive medium. An example of sound waves in a longitudinal direction is the tuning fork.

There is a lot of talk about gaps in the fossil record. This means that we do not necessarily have fossils for every organism that has ever lived. What do you think could account for these gaps in the fossil record?
Answers
Answer:
Explanation:
The rate decomposition of dead remains, to a large extent, determines whether there would be fossils left of the organism after it has been long gone or become extinct. Environmental factors (such as harsh weather condition and early insect invasion of dead remains) could increase the rate of decomposition of dead remains which could really make it difficult for fossils to be available for such organisms under these factors (especially if the organism is restricted to a particular region by nature) .

Answer: Mendel's research lead to several conclusions about the traits and its passing through generations. The two of the conclusion are different forms of a gene account for variation in the inherited traits and some alleles are dominant over others for a given trait.
Explanation
George Mendel was a famous biologist. His research was on genes and traits. His experiment shows how genes gets transferred from parents to offspring. Also he stated about the behavior and dominance and recessive nature of that alleles.
He also gives the possibility of dominance of a trait over other trait. The different forms of gene are responsible for various types of inherited traits in an organism.

If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: _________
Dependent: __________
Other variable(s): ________
Answers
Answer:
If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: temperature.
Dependent: leaf color.
Other variable(s): According to the information, there are no other variables.
Explanation:
When formulating a hypothesis, it is inevitable that the presence of variables on which the hypothesis is formed is established. The hypothesis raised is the effect of temperature on the color change of the leaf of a plant.
The independent variable, used in research work, is an element that does not depend on other variables but can influence the behavior of the dependent variable. In this case, the independent variable is the temperature. In addition, the independent variable can be managed to observe its effect on other variables.
An dependent variable is a characteristic that is influenced or modified by the presence of other variables, such as the independent variable of a study. In this case is the color of the leaf of a plant.
A student states that petrification occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution. What is wrong with this statement?
A.
Permineralization occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution.
B.
Petrification occurs when once-living tissues are replaced by minerals, preserving the organism's structure.
C.
Both A and B describe errors in the statement.
D.
Nothing, this statement is correct as is.
Answers
Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.
students observed several prepared slides of a process that occurs in a dividing onion cell. they observed haploid cells in one slide, centromeres that did not separate during anaphase in another slide, and two different cell divisions resulting in 4 daughter cells in other slides. Which statement is not true about the process that was observed?
1.) the slides were of an egg cell or sperm cell
2.) the process observed produce genetically different cells
3.) the number of chromosomes resulting from the process is reduced by half
4.) the observations suggest cellular reproduction and general growth and repair of the body.
Answers
Answer: pretty sure it could be “B”.
Explanation:
Meiosis produces 4 haploid cells -gametes- from a single diploid cell. The statement that is not true is 4). the observations suggest cellular reproduction and general growth and repair of the body.
Observed prepared slides:
haploid cells in one slide.centromeres that did not separate during anaphase in another slide.cell divisions resulting in 4 daughter cells in other slides.
According to this information, we can assume that the students are observing the occurrence of meiosis events.
MeiosisThrough Meiosis, a diploid cell (2n) produces four haploid daughter cells (n). Thes haploid cells are the gametes.
After DNA replication there are two meiotic phases.
The first one is a reductive phase, in which homologous chromosomes separate. In the second phase, the cell suffers a new, not reductive division.1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and become visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: Homologous chromosomes randomly align in the equatorial plane. Anaphase I: In this phase occurs the division and independent separation of homologous pairs. Each chromosome migrates to different poles. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Chromosomes of homologous pairs are already in the corresponding poles, and the nuclear membrane forms again in each pole. Cytokinesis occurs.2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes become lax again, and the nuclear membrane forms again. Cytokinesis occurs. Options1.) the slides were of an egg cell or sperm cell ⇒ Correct. It makes reference to gametes -haploid cells-.
2.) the process observed produce genetically different cells ⇒ Correct. After crossing over and independent segregation of chromosomes.
3.) the number of chromosomes resulting from the process is reduced by half ⇒ Correct. After the reductive phase.
4.) the observations suggest cellular reproduction and general growth and repair of the body. ⇒ INCORRECT. Mitosis is in charge of general growth and repair of the body, not meiosis.

Summarize cell division in prokaryotes
Answers
According to the research, the correct answer is that unicellular living beings like prokaryotes have their cell division by binary fission, forming two identical individuals (daughter cells).
What is binary fission?It refers to the process of cell division where first the deoxyribonucleic acid (DNA) is duplicated and then cytonesis occurs, which involves the separation of the cytoplasm.
In this sense, it gives rise to two daughter cells with identical genetic material, this is the reproduction method shared by certain yeasts, algae, bacteria and other prokaryotic organisms.
Therefore, we can conclude that the cell division mechanism of prokaryotes is through binary fission where two daughter cells arise.
