Chemosynthesis relies on which energy source? (1 point)
Olight
O thermal
O nuclear
O chemical
Chemosynthesis relies on chemical energy as its energy source. Therefore, option (C) is correct.
What is chemosynthesis?Chemosynthesis is a process by which certain organisms, such as certain bacteria and archaea, use energy obtained from chemical reactions to produce organic compounds. This process is similar to photosynthesis, but instead of using light energy, chemosynthesis relies on energy from chemical reactions.
In chemosynthesis, organisms use chemical compounds such as hydrogen sulfide, methane, and ammonia as sources of energy. These compounds can be found in environments such as deep-sea hydrothermal vents, where they are released from the Earth's crust. Organisms that use chemosynthesis to produce energy are called chemotrophs.
Chemosynthesis is important for the ecosystem in environments where sunlight is limited, such as in the deep ocean. Chemosynthetic organisms form the base of the food chain in these environments, providing energy for other organisms that cannot produce their own food through photosynthesis.

The primary goal of water-softening ion exchange systems is _____
B- removing magnesium and calcium from water.
A- Untreated water is subjected to high pressure, causing it to move through a semipermeable membrane, which captures contaminants
A-An ion exchange system would likely be chosen because it does not require specialized maintenance or regular replacement of components.
D-They are likely to choose reverse osmosis because it addresses a wider range of problems, including bacteria.
A-his treatment removes bacteria, but not other pollutants.
The primary goal of water-softening ion exchange systems is to remove magnesium and calcium from waters.
Water hardnessWaters that contain carbonates of magnesium or calcium are said to be hard. Soft waters have very little or no magnesium or calcium.
Hard waters are economically and domestically undesirable because they form scales in pipes and do not form lather with soaps, among other effects.
Thus, removing the magnesium or calcium is a way of softening hard waters.
One of the ways of softening hard waters is ion-exchange systems.

8. In order for Rick to safely lose weight, he should aim for 1 pound of weight loss per week, known as the "3500-kcalorie rule," which
states simply that you should reduce your daily kcaloric intake by 500 kcalories; over a seven-day week you would lose 3500 kcalories
which is approximately 1 pound. If Rick aims for his new target weight of 188 pounds by following the "3500-kcalorie rule," how long
would it take him to achieve his goal?
It will take Rick 188 weeks to achieve his goal of losing 188 pounds following 3500 kilocalories rule.
HOW TO LOSE WEIGHT?According to this question, Rick wants to safely lose weight using 1 pound of weight loss per week, known as the "3500-kcalorie rule".
This rule simply means one should reduce daily kilocalorie intake by 500 kcalories; over a seven-day week you would lose 3500 kcalories
which is approximately 1 pound.
This means if 1 pound is lost per week, 188 pounds will be lost in 1 × 188 = 188 weeks.

what does a line graph of a car accelerating look like
Answer: If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive). If the acceleration is negative, then the velocity-time graph is a downward sloping line (i.e., the slope is negative). If the acceleration is great, then the line slopes up steeply (i.e., the slope is great).

Why does natural selection act on it’s self?
Answer: Natural selection works against all organisms, and it can be thought of as the environment and forces acting to stop organisms from surviving and reproducing. Therefore, organisms which are able to survive can also pass on their DNA to the next generation. This “selects” for those DNA sequences.
Explanation:
Answer:
Natural selection is the environment and forces operating against all organisms in order to prevent them from surviving and reproducing. As a result, creatures that survive can transmit their DNA on to future generations. This makes those DNA sequences the ones to look for.
how do organisms differ from on to another?
Answer:
'genetic variation' enables natural selection which make organisms differ from one to another.

Which of the following results when a person’s hand is near an open flame?
A) Motor neurons activating the muscles of the hand cause the hand to move
B) Sensory neurons process incoming information and determine a response.
C) The brain is required to integrate incoming and outgoing information
D) Interneurons detect the change in temperature of the environment
Given what we know, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.
What happens when a person's hand is near a flame?We can say that the information from the heat being generated by the flame is received by sensory neurons in the person's hand. This information generates a pain response which is integrated as incoming information in the brain, which then produces a motor response to move the hand away from the flame, as an outgoing signal.
Therefore, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.

How are fossils important evidence of Evolution? Give three examples
(I’ll give points + brainalist)
Answer:
in explanation
Explanation:
1. fossils show our past ancestors and what we would have looked like before
2. you can use trace fossils (fossils left by an organism) to see how they lived and you can track how they lived their daily life
3.Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.
