Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
how do you prove the fact that green plant releases Oxygen gas in the process of photosynthesis explain the experiment.
Answer:
Aim : To prove that oxygen is produced during photosynthesis
Procedure : Place water plant in a beaker containing pond water.
Cover the plant with short stemmed funnel.Invert the test tube full of water and cover the stem of the funnel.While placing the test tube, ensure that the level of the water in beaker is above the level of stem of funnel.Expose the apparatus to the sunlight.
After few hours, gas bubbles will form and collect in the test tube.Test the gas in the test tube.
A glowing splinter bursts into the flame shows the presence of oxygen.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants
Which evidence is provided by fossil record
The fossil record
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
how are monosaccharides made from a disaccharide ?? And what’s the reaction called ?
Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond. (Lumen Learning to learn more, or to cite)

Answer:
- The building blocks of DNA molecules are amino acids. False
- DNA molecules contain a 5-carbon sugar called deoxyribose. True
- The nitrogen bases found in DNA molecules include adenine, cytosine, guanine, and thymine. True
Explanation:
The building blocks of the deoxyribonucleic acid (DNA) are nucleotides, while amino acids are the building blocks of proteins. Each nucleotide consists of one of four possible nitrogenous bases: two purines (i.e., adenine and guanine) and two pyrimidines (i.e., cytosine and thymine). In DNA, each nucleotide consists of one of these four nitrogenous bases, a five-carbon sugar molecule (called deoxyribose), and a phosphate group. The DNA molecule has a double-helix structure, where nitrogenous bases are inside the double helix while sugars and phosphates are outside. In DNA, cytosine always pairs with guanine and thymine always pairs with adenine.

Answer: Definition and models Contamination alludes to the presence of a substance or substances in the climate that is unsafe or harmful. The substances or poisons might be hurtful to human wellbeing, different creatures, and plants. When something hurtful enters the climate at a quicker rate than it tends to be scattered, there is contamination. or Contamination is that the presentation of hurtful materials into the climate. These unsafe materials are called toxins. Poisons might be normal, as volcanic debris. they'll even be made by human activity, similar to waste or overflow created by industrial facilities. Contaminations harm the norm of air, water, and land. Explanation: Both describe what pollution means I hope this helps you

Why is diffusion such an efficient process
for all cells?
A. It does not require energy.
B. It occurs so quickly.
C. The high amount of energy used during diffusion is offset by
the amount it creates.
Answer:
A.
Explanation:
Diffusion does not require energy. It's depends on the concentration gradient of the two molecules.
Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the migration of substances from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
Diffusion does not require any type of energy for the movement of ions, molecules, or substances. It is a very feasible form of migration of substances.
Diffusion is a type of passive transport and hence takes place in a dropping manner without any expenditure of energy.
Therefore, Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

Why is the parietal lobe sometimes called the
"association lobe"?
Answer:
The parietal lobes are primarily responsible for receiving and processing sensory input such as touch, pressure, heat, cold, and pain. The parietal lobes are also involved in the perception of body awareness and the construction of a spatial coordinate system (mental map) to represent the world around us
Answer:
The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. ... The name comes from the parietal bone, which is named from the Latin paries-, meaning "wall".

Which statement describes the general relationship between the temperature and the absolute brightness of main sequence stars?
As temperature decreases, absolute brightness increases.
As temperature decreases, absolute brightness remains the same.
As temperature increases, absolute brightness increases.
As temperature increases, absolute brightness remains the same.
Answer:
As temperature increases, absolute brightness increases
Explanation:
As temperature increases, absolute brightness increases
As temperature increases, absolute brightness increases. Therefore, option (C) is correct.
What is absolute brightness?Absolute brightness, also known as absolute magnitude, is a measure of the intrinsic luminosity of a star, which is its total energy output per unit of time. Absolute brightness is defined as the brightness a star would have if it were placed at a standard distance of 10 parsecs (32.6 light years) from Earth. This standard distance allows astronomers to compare the luminosity of stars with different distances from Earth.
Absolute brightness is an important measure for astronomers because it helps them determine the true luminosity and size of a star. It also helps astronomers classify stars based on their luminosity and temperature, which is related to their evolutionary stage. For example, main sequence stars, which are stars in the process of burning hydrogen to helium, are classified based on their temperature and absolute brightness
