What is an environment?An environment may be defined as anything that is present in the surroundings of a living organism. It includes two types of factors, i.e. biotic and abiotic factors. The term environment was given by Carlyle.
Human Activity is the major cause of Increased Greenhouse Gas Concentrations. Over the last century, the combustion of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Therefore, the action which would most likely increase the amount of carbon in the environment is choosing to burn coal to generate electricity. Thus, the correct option for this question is A.

Answer:
The correct answer is : approximately 3 gT yr^-1 decrease
Explanation:
Carbon dioxide is contribute and removed from the atmosphere by various type of activities that are human activities, biological input or biological removal and geological input or geological removal.
Adding carbon dioxide can be from biological inputs mainly respiration and removed from atmosphere mainly through biological removal mainly photosynthesis.
Both photosynthesis are complementary metabolic process that play major role of adding and removal of carbon dioxide. There is a decrease of 3gT yr^-1 approximately on the annual basis due to these biological process.

Answer:
Explanation:
Australopithecina or Hominina is a subtribe in the tribe Hominini. The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus,[2] and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus. All these related species are now sometimes collectively termed australopithecines or homininians.[3][4] They are the extinct, close relatives of humans and, with the extant genus Homo, comprise the human clade. Members of the human clade, i.e. the Hominini after the split from the chimpanzees, are now called Hominina[5] (see Hominidae; terms "hominids" and hominins).
While none of the groups normally directly assigned to this group survived, the australopithecines do not appear to be literally extinct (in the sense of having no living descendants) as the genera Kenyanthropus, Paranthropus and Homo probably emerged as sister of a late Australopithecus species such as A. africanus and/or A. sediba.
The terms australopithecine, et al., come from a former classification as members of a distinct subfamily, the Australopithecinae.[6] Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines".[7][8]
The australopithecines occurred in the Plio-Pleistocene era and were bipedal, and they were dentally similar to humans, but with a brain size not much larger than that of modern apes, with lesser encephalization than in the genus Homo.[9] Humans (genus Homo) may have descended from australopithecine ancestors and the genera Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus are the possible ancestors of the australopithecines.[8]
The generation of radioactive wastes such spent (used) reactor fuel, uranium mill tailings, and other radioactive wastes is a significant environmental hazard associated with nuclear power.
What impact of nuclear power, energy on the environment?Nuclear energy is still readily available, despite the fact that it isn't strictly renewable (since there is only a finite amount of uranium on Earth).
Additionally, even though using nuclear energy to produce electricity is a carbon-free process, building new nuclear energy facilities and mining the uranium fuel have their own environmental consequences.
For millions of years, these substances may continue to be radioactive and hazardous to human health. The trash that nuclear power generates is the most urgent environmental concern.
During the course of a nuclear power plant's operation, a few different types of radioactive material are created, most notably used reactor fuel and the tailings from uranium mills.
Therefore, These pose numerous risks to the health of both people and the environment if they are not handled and disposed of properly.

A stroke victim has great difficulty moving his right hand and right leg. He also has trouble speaking. Which of his cerebral hemispheres is most likely to have been damaged
Answer:
The correct answer is left cerebral hemisphere.
Explanation:
The left cerebral hemisphere of the brain is accountable for the motor control of the right side of the body, for sensory stimulus from the body’s right side, for analysis and calculations, for the speech, comprehension, and language, for the recognition of letters, words, and numbers, and for time and sequencing.
The left cerebral hemisphere is accountable for the processing of the sensory information and motor information for the body’s right side. Thus, as left cerebral hemisphere monitors the movement of the body's right side, so, based on the extremity of the stroke, which may result in motor skill impairment or functional loss of the right side of the body, shows that the left side of the brain has got affected.
The cerebral hemisphere most likely damaged in this person is the LEFT hemisphere.
The cerebrum can be divided into two major hemispheres known as the right and left cerebral hemispheres.The left cerebral hemisphere is involved in the control o the right side of the body. This hemisphere (left hemisphere) is associated with science and/or mathematical skills, language functions (e.g., grammar, vocabulary), etc.In conclusion, the cerebral hemisphere most likely damaged in this person is the LEFT hemisphere.

What is a relatively dense aggregation of fishes, squid, and other mesopelagic organisms capable of reflecting a sonar pulse that resembles a false bottom in the ocean. Its position varies with the time of day.
Answer:
Deep scattering layer, DSL
Explanation:
The deep scattering layer (DSL) also known as "deep sound layer", refers to an oceanic deep layer, more or less defined, that reflects sound and that is formed by a wide variety of animals. It is present in almost every ocean. It is produced by the presence of many organisms of different species that can disperse the sonar waves sent by a sonar equipment.
It was discovered through the ships´ sonar. Whenever they met a layer in which the sound hit, and was often confused with the bottom of the ocean. This is why the DSL is refered to as the "fake bottom".
These animals form layers of not less than 10 meters thick and might easily reach up to 50 meters thick. These layers are often found between 50 and 200 meters deep and can be seen going up and down every day according to the daily vertical migration.

Which hormone is essential to our ability to maintain our fluid levels? Which hormone is essential to our ability to maintain our fluid levels? cortisol thyroxine insulin aldosterone
Answer:
Aldosterone.
Explanation:
Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.
In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.
Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.
