I did this on my USATestPrep for my 9th grade honors bio class nd i got it correct. 12/13/20
Regarding the meiosis, the questions that are mentioned in options A, C, and E should be asked. Sister chromatid and homologous chromosomes separation occur during meiosis, and the gametes form the diploid zygote.
What is meiosis?
Meiosis is a process that involves multiple sub phases, such as meiosis I and meiosis II. The meiosis has prophase I ( leptotene, zygotene, pachytene, diplotene, and diakinesis), metaphase I, anaphase I, ,telophase I, and cytokinesis. Except for the five stages of prophase I, meiosis II includes all of these phases.
In meiosis I, the homologous chromosomes cross over, and recombination takes place in prophase I. In anaphase I and telophase I, the homologous chromosome separates, while in meiosis II, sister chromatids separate. At the end of the meiosis, four haploid cells are formed.
hence Regarding the meiosis, the questions that are mentioned in options A, C, and E should be asked. Sister chromatid and homologous chromosomes separation occur during meiosis, and the gametes form the diploid zygote.

Stuart is listing the changes to matter and energy that occur during the process of photosynthesis. Which of these examples should he include in his list?
A. nuclear changes that convert hydrogen and oxygen into carbon
B. chemical changes that convert carbohydrates into smaller molecules
C. changes that convert light energy into chemical energy stored in carbohydrates
D. changes that convert chemical energy into heat and light
Answer:
C. Changes that convert light energy into chemical energy stored in carbohydrates
Explanation:
Just had this question on a bio assignment.
Photosynthesis occurs in plants containing chlorophyll in which the solar energy entrapped is converted into the chemical fuel needed for energy generation.
The correct answer is:
Option C. Changes that convert light energy into chemical energy stored in carbohydrates.
This can be explained as:
The leaves of plants capture the rays and with the help of water and carbon dioxide create glucose and oxygen.The nourishment or the nutrient includes carbohydrates that get broken in the presence of solar energy and experience chemical changes.Therefore, during photosynthesis light energy is transformed into chemical power.

What is the best explanation for the faster times of the group fed a pre-race meal of bread with bananas and honey
Answer:
Bread, bananas and honey have carbohydrates.
Explanation:
The group fed a pre-race meal of bread with bananas and honey because bread, bananas and honey have high amount of carbohydrates which give quick energy to the athlete. This carbohydrate is a macromolecule which is quickly converted into micromolecule i. e. glucose that is absorbed by the cell and the mitochondria of the cell produces energy in the form of ATP that is used by the athlete in running.

how can we tell that environment is actually changed in the past
Answer:
Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
1) The planet's average surface temperature has risen about 2.05 degrees Fahrenheit (1.14 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 40 years, with the six warmest years on record taking place since 2014. Not only was 2016 the warmest year on record, but eight months out of that year — from January through September, with the exception of June — were the warmest on record for those respective months.
2) The ocean has absorbed much of this increased heat, with the top 100 meters (about 328 feet) of ocean showing warming of more than 0.6 degrees Fahrenheit (0.33 degrees Celsius) since 1969. Earth stores 90% of the extra energy in the ocean.
3) The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 279 billion tons of ice per year between 1993 and 2019, while Antarctica lost about 148 billion tons of ice per year.
4) Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska, and Africa.
5 )Satellite observations reveal that the amount of spring snow cover in the Northern Hemisphere has decreased over the past five decades and the snow is melting earlier.
6) Global sea level rose about 8 inches (20 centimeters) in the last century. The rate in the last two decades, however, is nearly double that of the last century and accelerating slightly every year
7) Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades
8) The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.
9) Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30%.13,14 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the ocean. The ocean has absorbed between 20% and 30% of total anthropogenic carbon dioxide emissions in recent decades (7.2 to 10.8 billion metric tons per year).
Shorter version: 1) Global Temperature Rise
2) Warming Ocean
3) Shrinking Ice Sheets
4) Glacial Retreat
5) Decreased Snow Cover
6) Sea Level Rise
7) Declining Arctic Sea Ice
8) Extreme Events
9) Ocean Acidification

Which best describes the cycle that ensures fresh water, which is vital for carrying out metabolic processes, is available?
Answer: B. evaporation, condensation, precipitation
Explanation:
The cycle that ensures that fresh water is available is called the Hydrological cycle and it involves several key processes.
As it is a cycle, none of the processes can be considered first but if any could, it would be evaporation. This is when water on the surface is heated and becomes water vapor (gas) and rises towards the atmosphere.
Condensation occurs as the water vapor rises because the further up you go, the colder it gets. These water vapor particles will thus condense and clump together to form clouds.
These clouds keep getting larger until they are too heavy to be carried by the atmosphere in which case they fall to the ground as rain the process known as precipitation.

When a red flowered pea plant was crossed with a white flowered pea plant, it was found that all plants in the F1generation carried only red flowers. If these plants are self crossed, i) Find the genotypic ratio that we can expect in F2 generation ii) What is the phenotype and genotype of F1 generation. Draw Punnett square for F2
Answer:
The correct answer is -
i) genotype of F2 - 1:2:1 = dominant:heterozygous:recessive
ii) genotype of F1 - all heterozygous dominant
phenotype - all red
Explanation:
In the cross of red- flowered plant and white flowered plant the offspring produces red flowers that s only possible if the parent red flower plant has both alleles in dominant condition.
For the F1 the gametes will be R, R and r, r
from the Punnett square, we can see all the offspring are heterozygous (Rr) in genotype and red in phenotype
For F2 the gametes will be - R, r, and R, r
From the punnet square, the genotype we get is 1:2:1 = dominant:heterozygous:recessive

The part of the plant where you would find the most cellulose is ? ( dont say cell walls , im looking where at
a-leaves
b-roots
c-branch
d-stem
Answer:
d-stem
Explanation:
Cellulose is most abundant in meristems tissues which are present in the tips of the root and stem and in the cambium between the xylem and the phloem and under the epidermis of the trees and shrubs, therefore it is abundant in the stems.
Meristems are also found in other parts of the plant but it is mostly abundant in the stems.
Meristems are the cells that are responsible for the cell growth and elongation.

What are the 5 steps of Self- Pollination in flowers?
Answer:
Plants avoid self-pollination by a whole range of different mechanisms. One of them is kiwifruit, and what kiwifruit does is it has its male and female flowers on different plants. So a female plant can't actually pollinate itself at all – it's got to get pollen from somewhere else.
