How do humans cycle carbon from the biosphere to the atmosphere? (1 point)
by respiration
by driving cars that use gasoline for fuel
by eating plants
by planting vegetable crops
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
Explanation:
Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.
What is Carbon Cycle?
The movement of carbon from the reservoir to reservoir is known as the carbon cycle. The carbon Cycle occurs through the atmosphere, oceans, and through living and dead organisms.
Humans during respiration inhale Oxygen and exhale Carbon-dioxide, vehicles also emit smoke consisting mainly of carbon, plants' bodies also contain a proportion of carbon.
Therefore, Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.
Answer:
Skull three
Explanation:
the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature
It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.
What is the basic evolutionary changes in the group mentioned ?As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.
It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.
Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.

Sam has a mutation in a gene that affects the function of a transfer RNA (tRNA). Human cells have 20 different types of tRNAs, and each adds a different amino acid to growing peptide chains, which form proteins. Based on what you know so far, would you expect this mutation to affect all proteins produced in Sam's cells? Explain your reasoning.
Answer:
No
Explanation:
The mutation is not expected to affect all the proteins produced in Sam's cells because each protein has a different structure and functions. Proteins are polymers of amino acids and the component amino acid for each protein diffesr. Hence only the proteins whose constituent amino acids include the amino acid being carried by the mutated tRNA would be affected. Others whose constituent amino acids do not include the amino acid being carried by the mutated tRNA would function normally.
Explain a wedge and give 3 examples.
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.
The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.
The wedge works on the principle of an inclined plane.
The Door Stop Is an example of one,
A Knife is a very thin wedge because it slices through objects

Evidence:
Reasoning:
Rebuttal:
Answer:
Explanation:The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. ... Cellular respiration releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.

write a summary about the cell theory
Answer:
Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:
all organisms are made up of one or more cells,
all the life functions of an organism occur within cells,
all cells come from preexisting cells.
Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:
all known living things are made up of one or more cells,
all living cells arise from pre-existing cells by division,
the cell is the fundamental unit of structure and function in all living organisms,
the activity of an organism depends on the total activity of independent cells,
energy flow (metabolism and biochemistry) occurs within cells,
cells contain hereditary information (DNA) which is passed from cell to cell during cell division,
all cells are basically the same in chemical composition in organisms of similar species.
The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Later, Rudolf Virchow made significant contributions to this theory.
Why is it important to study cell theory?Cell theory is critical for understanding biology because cells are the foundation of all life. We can have unicellular organisms such as bacteria and yeasts. cell division, the division of a cell from one to two to four, is the foundation of all living things' growth and development.According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
