Why is reducing caloric intake insufficient for a person to loose weight in a healthy way?
Because there are several factors that determine weight loss or gain and reducing calorific intake is just one of them (for reducing weight loss). Other factors that should be considered is exercise. Doing regular exercise ensures that the metabolic rate of the body is increased so much of the calories are burned even after intake. Having a lower metabolic rate can result to increased weight gain even with low calorie intake.
Which of the following statements is considered true of Neanderthals?
A. They had some system of religious beliefs about afterlife.
B. They evolved into homo sapiens.
C. They had smaller brains than homo sapiens (modern humans).
D. They emerged after the ice age.
Answer:
A. They had some system of religious beliefs about afterlife.
Explanation:
Answer:
They emerged after the ice age.
Explanation:
Neanderthals are also known as Homo neanderthalensis. The earliest fossils of neanderthals was found in Europe and dated 450,000 and 430,000 years ago. They were expanded into central Asia and south west.
Scientists believed that neanderthals lived 120,000 in Europe and emerged in the cold ice age. The became extinct as the cold ice age was converted into the warm climate.
Thus, the correct answer is option (D).
if there is no oxygen around the sun then how does the sun burn is the sun really burning can the process be called combustion
The Sun is not burning through combustion with oxygen but operates through nuclear fusion, which allows it to emit energy for billions of years, unlike combustion which would only sustain it for a very short period.
The Sun does not burn in the way that we think of materials burning on Earth, such as wood or coal. In a combustion reaction, a substance reacts with oxygen to release energy in the form of heat and light. However, the Sun operates through a different process known as nuclear fusion, where hydrogen nuclei combine to form helium, releasing immense amounts of energy in the process.
Assuming the Sun was made entirely of oxygen and combustion was possible, when an oxygen atom combusts, it would release an electron-volt of energy. But given the chemical bond energy typical of combustion reactions (about 1 eV), the Sun would have a very short lifespan, far shorter than what we observe. Even if the Sun were made of the best anthracite coal and oxygen, it could only sustain its current level of heat output for less than 1500 years given the huge amount of energy it emits.
Therefore, it is not combustion that powers the Sun, but rather the process of nuclear fusion, which is capable of producing the Sun's energy for billions of years.

Match the genes with their linkage ability.
genes close to each other
genes on different chromosomes
genes apart from each other,
but on the same chromosome
unlinked genes
not so strongly linked genes
strongly linked genes
Reset
Next
Answer:
The genes, which are situated in close proximity on a chromosome exhibits a greater linkage tendency. This signifies that it is very much possible that these genes are going to be transmitted together to the next generation. In contrast, the genes, which are found on different chromosomes exhibit a slight chance to be passed on together. Thus, the unlinked genes are the genes present on different chromosomes, the not so strong linked genes are the genes that are far from each other, but on the similar chromosome, and the strongly linked genes are the genes close to each other.
Answer:
1. Strongly linked
2. Unlinked
3. Linked, but not strongly
Explanation:
The genes closest to each other are strongly linked genes. The genes that are farther away from each other but on the same chromosome are linked, but not strongly. The genes on different chromosomes are unlinked.
14. What are vaccines for influenza made from?
antibodies to the virus
weakened viruses
parts or products of a virus
dead, whole viruses
ells
Answer:
Option D
Explanation:
In the general process of producing vaccines for any viral diseases, the viruses are cultivated in any carrier animal such as hen and then these virus fluids are extracted from the body of the test species. The virus in the virus solutions are inactivated (killed) and the virus solution i.e antigen is cleaned , purified and tested to make vaccines for influenza virus.
Hence, option D is correct
Final answer:
Influenza vaccines are made from live weakened viruses, killed or inactivated viruses, or molecular subunits of the virus to build immunity and prevent the flu. They typically provoke an immune response without causing disease.
Explanation:
Vaccines for Influenza
Vaccines for influenza are primarily designed for prevention and are an essential tool in controlling viral diseases by building immunity. The influenza vaccines can be made from several different materials, including live weakened viruses, killed or inactivated viruses, and molecular subunits of the virus. These different types of vaccines work by stimulating the body's immune system to recognize and fight off the virus should the person become exposed to the actual virus in the future.
Influenza vaccines that use live weakened viruses are often called live attenuated influenza vaccines (LAIV). They contain a version of the virus that has been modified so that it cannot cause illness in healthy individuals. However, there's a very low risk that this type of vaccine could revert back to a harmful form. The inactivated influenza vaccines (IIV) contain viruses that have been killed and cannot cause the flu. Subunit vaccines, which include recombinant influenza vaccines (RIV), contain only pieces of the flu virus — generally protein subunits — that are enough to provoke a protective immune response without risking the introduction of live or killed viruses.
One example of vaccine production for flu includes growing influenza virus particles in chicken eggs, which are then harvested and chemically treated to render them noninfectious. These particles are purified and used to make the vaccine, which is administered by injection.
RNAi is a technique that silences genes by targeting them and degrading their mRNA. How can this technique be used in scientific laboratories?
A. RNAi has been used in laboratories to make bacteria more susceptible to antibiotics, but has limited application in eukaryotic cells.
B. RNAi is a powerful tool for degrading mRNA, but because it doesn't degrade other types of RNA, its use is limited.
C. RNAi is observed in nature, but it can't be used in laboratories.
D. RNAi allows scientists to turn off one gene specifically to study its effect.
Answer:
(D). RNAi allows scientists to turn off one gene specifically to study its effect.
Explanation:
RNAi (RNA interference) can be defined as a process, which involves inhibition of gene expression by degrading the targeted mRNA molecules. This technique is widely used in laboratories to study the functions of different genes by targeting them.
For this, a dsRNA molecule is formed having a sequence complementary to target gene and introduced into the cell or organism. This RNA is recognized as exogenous RNA and triggers activation of RNAi pathway.
RNAi pathway leads to a significant decrease in expression of a target gene. Hence, physiological role of the targeted gene product can be check by studying the effect of decrease in its expression.
Thus, the correct answer is option (D).

C. moves closer to equilibrium
D. is unchanged
Answer:
B. is increased
Explanation:
As molecules are formed from metabolism, entropy is increased and the universe becomes less disordered.
The entropy or disorder of a system increases as metabolism occurs and molecules are formed in line with the Second Law of Thermodynamics. Therefore the correct answer is option B. Entropy is increased.
Explanation:The correct answer is B. Entropy is increased. Entropy is a measure of irregularity, randomness, or unpredictability in a system and is a key principle in thermodynamics. As metabolism occurs and molecules are formed the entropy or disorder, of the system increase meaning the universe becomes more disordered. This is in accordance with the Second Law of Thermodynamics which contends that in an isolated system entropy never decreases rather it either remains constant or increases.

All macromolecules are made mostly of the same six elements. What are
those six elements?
Answer:
Carbon, hydrogen, oxygen, nitrogen, phosphorous, and sulfur.
Explanation:
Macromolecules such as carbohydrates or lipids are made of a selection of these six elements. Carbohydrates are made out of carbon, hydrogen, and oxygen--or "CHO" for short. Lipids are made out of carbon, hydrogen, and oxygen as well. Proteins are made out of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur (CHONs, the s is lowercase because sulfur does not usually appear in proteins). Nucleic acids are made out of carbon, hydrogen, oxygen, nitrogen, and phosphorous (CHONP).
Hope this helps!
Final answer:
Macromolecules, crucial for life, are composed mostly of six elements: carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S). Carbon plays a central role as the backbone due to its ability to form four covalent bonds.
Explanation:
All macromolecules, which include proteins, nucleic acids (RNA and DNA), carbohydrates, and lipids, are composed mostly of the same six elements. These elements are carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S). The carbon atom is a fundamental component for all macromolecules due to its unique properties, which enable it to form covalent bonds with up to four different atoms. This makes carbon the key structural component, or "backbone," of the macromolecules.
Within these macromolecules, nucleic acids contain C, H, O, N, and P, and are composed of monomers called nucleotides. Proteins are primarily composed of C, H, O, N, and smaller amounts of sulfur. Proteins are built from 20 naturally occurring amino acids, which link together through dehydration synthesis. The other macromolecules, carbohydrates, and lipids also contain these elements in various configurations.

A machine can never be 100% efficient because some work is always lost due to
Answer:
Friction
Explanation:
The efficiency of a machine depends upon the percentage ratio of output work to the input work. More the difference between the input and output work, lesser will be the efficiency of the machine. In real machines, the output is always less than the input because a lot of work is consumed against friction, resulting in reduced output.
The formula for efficiency is:
Efficiency= ( Output work/Input work) x 100%
Since the output will always be lesser than the input, the ratio of output/input will always be lesser than 1 and, therefore, the efficiency will always be lesser than 100%

What is a reproductive strategy?
A. The number of alleles an organism passes on
B. The DNA that is passed onto an offspring
C. The adaptations that an offspring passes on
D. The method an organism uses to produce offspring
Answer:
Reproductive strategy is the method an organism uses to produce an offspring.
Explanation:
The mode of reproduction and the number of reproductive phases in an organism’s lifetime all are reproductive strategies. Organisms can reproduce sexually as well as asexually. In some organisms reproduction occurs just once in their lifetime. Reproduction marks the end of their lifetime.
Thus the number of offspring they produce would be also large. Such kind of reproduction is called semelparous reproduction. But in iteroparous reproduction an organism has several reproductive phases in its lifetime .

why does fossil formation require a large amount of time? would it have the same results over a shorter period?
ANSWER:
Fossils take a lot of time to form because the decay of organisms takes long time. Organisms decompose quickly when they are exposed to oxygen and so it is not easy to get their fossils.
EXPLANATION:
To get fossils, organisms must be buried deep so that they decay. When an organism gets eaten by microbes or decomposes, it cannot become a fossil. The process of decay is a long one as the hard parts of the body like bone and teeth take a long time to decay. Over a short period of time, we cannot get fossils because in short time period, only soft parts of the body decay which do not offer much explanation about the organism.Why does the potential energy and the kinetic energy change when the skateboarder is at the top or the bottom of the hill why do you think this change occurs
Answer:
Potential energy is gaining all the way to the top of the hill due to the increase of height (gravitational pull) on the skateboarder. At the top of the hill potential energy will reach its highest point. Then going down kinetic energy increases as potential energy decreases.
Explanation:
Answer : The potential energy and kinetic energy are always in flux. At the top of the hill, potential energy is at its highest and kinetic energy is at its lowest because the skateboarder stops for just a moment before being pulled down the hill by the force of gravity. At the bottom of the hill, kinetic energy is the highest because the skateboarder reaches maximum speed

Explanation:
Because nothing is eating the zooplankton then they will increase and the paddle fish will decrease because they are being hunted... Hope this helps!!!
Answer:
Option B, The population of paddlefish will decrease, while the population of zooplankton will increase.
Explanation:
Since, it is given that humans living around the river started hunting the paddlefish thus their population will definitely decrease. As the number of paddlefish decreases the extent to which they feed on zooplanktons will also decrease. Thus, the population of zooplanktons will increase with no or limited disturbance.
Population of lamprey which feed on paddlefish will start decreasing as their food i.e paddlefish has started declining.
Thus, option B is the correct answer.
