How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

What led to scientists accepting Mendel's ideas?
A. Scientists discovered chromosomes and DNA.
B. Scientists discovered the scientific method.
C. Scientists repeated his experiments using other plants.
O D. Scientists developed the law of independent assortment.
Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.

Explanation:
The third type of the plate boundary that occur between the two plates laterally. Each plate slide pass each other along the giant fracture of the earth crust.
The transformation faults are segments of oceanic ridges.
The rocks are cut and displaced by the movement in opposite directions. The rocks are of different type and ages.
The transform boundaries at the lithosphere is not even created nor destroyed. The transform boundaries in the lithosphere can be found in the sea floor. It occurs to change the length of the plates.

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

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.

Why is glucose the first option for energy release?
Why not proteins or fats?
Answer:
firstly you can follow me I can give you answer
Glucose is stored calories in the form of fat, and are the first to go becuase they provide the most long-term energy. Lipids are essential to your vital organs in keeping them protected and functional, like the lipids from healthy fats in your cardiovascular system. Proteins, like fatty acids, are utilized by your cells to undergo a variety of processes, including mitosis. Overall, it is a process most likely determined by evolution, and our bodies prioritize giving us the most energy at the moment, which is why you burn calories while running, playing sports, and even playing chess (chess players can burn upwards of 6,000 calories in a single 12-14 hour game, perhaps even longer).

Explanation:
Where in the cell does the krebs cycle part of cellular respiration occur ?
Answer:
In the mitochondrial matrix
Explanation:
The mitochondria is an organelle within the cytoplasm of the cell. It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into [tex]CO_{2}[/tex] (carbon dioxide) and [tex]H_{2} O[/tex] (water) to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
(glucose) (oxygen) (carbon dioxide) + (water)
The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.

Explain why there are five different climate zones on Mount Kilimanjaro
Please answer in a full paragraph with reasons to support your answer
Answer:
Mount Kilimanjaro is made up of five distinct climate zones. They are as follows; Cultivation, Forest, Heather-Moorland, Alpine Desert, and Summit climate zones. This region of the mountain receives the greatest annual rainfall. It also has many rivers formed by glacier run-off from the top of Kilimanjaro. This zone is made up of farmland and small Chagga villages. The rainforest quickly gives way to the Heather zone. The temperatures here are erratic. The daytime temperature can soar above 100° F (40oC) yet drop below freezing (32° For 0° C) at night. These temperatures combined with less rain, gusting winds, giant heathers, wild grasses, and a rocky trail replaces the rainforest very quickly. Some of the heather shrubs can grow to over 30 ft. high. The rainforest circles a majority of Mount Kilimanjaro. However, most of the rain on the mountain falls on the south and the east side. The forest is much thicker here than to the north on the Kenyan side of the mountain. The highland desert zone region of the mountain is a strange place, truly deserving the title of Desert. The annual rainfall is less than 8 inches a year and what plant life exists at this altitude has to put up with the oppressive sun and sub-zero temperatures—all in the same day. This area also shows off its violent past with fields of volcanic rock of all shapes and sizes. The artic zones lower section of this section is made up of loose dirt and gravel known as scree. Scree is quite difficult to climb. That is part of the reason the summit attempt begins at night when the evening dew has settled and frozen. This allows the scree to knit together making it a more stable path.
What are three types of sedimentary rocks? How do they form?
Pls give a legit answer thats not off of google for brainly, thank you.
Answer:
Three types of sedimentary rocks are, clastic, organic (biological), and chemical. Clastic rocks are formed by made up of pieces (clasts) of pre-existing rocks. Organic rocks are formed by accumulation and lithification of organic debris, such as leaves, roots, and other plant or animal material. Last but not least chemical rocks are formed by precipitation of minerals from water. Precipitation is when dissolved materials come out of water.
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.
