analyze features of scientific diagrams for clarity and readability. Sorry if this is hard
Answers
Explanation: Textbooks remain as major learning aids in all levels of education worldwide. Thus, textbooks must constantly be subjected to critical analysis in order to establish their curricular usefulness. This paper analyzed four commercial science textbooks designed for third grade Filipino learners. The four textbooks were analyzed according to readability and comprehensibility, content, and mechanical features. Readability was evaluated using popular readability formulas, while comprehensibility was determined using the Sonmez’s formula and the cloze test methods. The content features were the textbooks’ alignment with national science standards, conceptual errors, and level of gender bias. Finally, the mechanical features were focused on printing and lay-out, and handiness of the textbooks. Readability analysis revealed that that the textbooks were written three to four grade levels higher, and two to three years older than their intended users. The dominant reading ease of the four textbooks ranged from fairly easy to easy, which means that the texts are suitable to sixth and seventh graders. The texts were highly to perfectly aligned with the country’s national science standards. Three textbooks are generally gender fair while one has a low-level male bias. The average error/conceptual problem density is at one error in every six to eight pages. Misidentifications are most common conceptual problems in the textbooks. Finally, the textbooks are noted very good in printing, lay-out, paper quality, binding, and handiness.
A scientist put red blood cells in water that contained salt. Over time, the red blood cells burst. What is most likely true?
The concentration of water inside the cell was greater than in the salt water.
There was a higher concentration of salt in the water than in the cells.
There was a lower concentration of salt in the water than in the cells.
The concentration of water in the cells and salt water were equal.
Answers
Answer: It is most likely true that there was a lower concentration of salt in the water than in the cells because when blood cells are put in a hypotonic solution such as pure water, the little to no salt concentration in the water causes the cells to swell and burst. This would occur because the water would try to dilute the solution inside of the blood cell and which would, therefore, cause it to burst. Hope this helps!
Explanation:
Answer: C. There was a lower concentration of salt in the water than in the cells.

Explanation:
Answer:
B. era
Explanation:
The word epoch means: a period of time in history.
We want to find a synonym for epoch, or a word that has the same meaning. So, if we were to replace epoch, the sentence would be the same.
Calendar: a chart showing the days, weeks and months of a year
Era: period of history that is long and distinct
Millennium: period of 1000 years
Timeline: a graphic representation of time passing
The word that makes the most sense as a synonym for epoch is era.
Therefore, the correct answer is B: era.

Also please do not put a random answer or you will get reported and lose your pointsss so please PLEASEEEEEEEEEEEEEEE
Answers
Answer:
Yes, I believe genetic variation is higher in offspring depending on the reproductive process; especially through process 2 due to the blending/combination of DNA from two parents rather than DNA being duplicated from a parent cell.
Explanation:
Process 2 is the blending of genes from two parents while process 1 is essentially direct DNA duplication from one parent cell. Take for example humans which are reproduced by two parents. Across the world humans vary greatly in their traits, take for example people with red hair, brown hair, green eyes, blue eyes, right handed, left handed, etc. This is a demonstration of genetic variation as humans over thousands of years have reproduced and passed on traits from two parents which overtime become more and more varied. Compared to process 1, which is just direct duplication of DNA from the parent cell rather than 2 parents reproducing and sharing traits/DNA into their offspring.

2. The respiration system brings air into the lungs by expanding, this oxygen is absorbed into the circulatory system through the alveoli which have capillaries with extremely thin walls, allowing oxygen in and carbon dioxide to escape. The oxygenated blood is carried to the heart which uses some of it, the pumps the rest throughout the body so that every organ and cell has enough oxygen, and when the oxygen is used by your body it creates the waste product carbon dioxide which is carried through the bloodstream, back to the alveoli, and exhaled.

Plants use specialized structures to increase their likelihood of reproduction. Which characteristic of plants would be useful in attracting bats as a vessel for dispersal?
A. The plant produces flowers that put off a fragrant scent.
B. The plant produces flowers that grow into fruit.
C. The plant produces flowers that make pollen.
D. The plant produces flowers that are bright and colorful.
Answers
In tropical, subtropical rainforests, and desert temperatures all over the world, where many plant species depend on bat pollination for reproduction, bats are particularly significant pollinators. Thus, option A is correct.
What is attracting bats as a vessel for dispersal?Chiropterophily refers to the practice of bats pollinating plants. Many bat-pollinated plants have light-colored nocturnal flowers (in contrast, bees are mostly attracted to bright, daytime flowers).
Over the course of 50 million years, bats and archaic groups like bananas underwent evolutionary change.
The plant's adaptations for bat pollination include nighttime blossoming, a potent scent that draws bats from all over the world, as well as an abundance of readily available nectar and pollen.
Therefore, the plant produces flowers that put off a fragrant scent.
