What would happen if photosynthesis stopped happening on earth?a; there would be more oxygen in the air
b ; sun would produce less energy
c ; carbon dioxide levels would increase
d; Biodiversity would increase in rain forest

Answers

Answer 1
Answer:

The correct answer is option C

Photosynthesis is the process by which green plants make their own food by the help of carbon dioxide, sunlight and chlorophyll. The green plants produce oxygen in the air and utilize the carbon dioxide present there. If there will be no photosynthesis on the earth then there will be increased amount of carbon dioxide on earth.
Answer 2
Answer:

C. carbon dioxide levels will increase

DNA plays a major role in heredity, composing the genes that are passed down from parent to offspring. It also plays a major role in the everyday workings of your cells. It does this by creating molecules, such as enzymes, that regulate cell functions. These enzymes belong to a larger class of molecules known as A) RNA. B) proteins. C) ion pumps. D) amino acids

Answers

Answer;

B. Proteins.

Explanation;

-Information that is stored in DNA molecules is used to manufacture proteins through the process of transcription and translation.

-During transcription, DNA molecules are used to generate mRNA (messenger RNA), which then undergoes translation in the cytoplasm to generate proteins. These proteins include enzymes that control or regulate and catalyze different biological reactions in the body.

- Additionally, one of the characteristic of protein is being protein in nature which means like proteins they are produced through translation in the ribosomes.

Which is an advantage of genetic engineering?

Answers

Great minds combined with technological advancements have a lead to creations and achievements that would have been impossible. Whatever great scientist of the past has achieved have already been surpassed or improved through modern and innovative ideas and processes. An excellent example of which is the direct manipulation of an organism’s DNA, also known as genetic engineering or genetic modification (GM). Coming from the terms genes and modify, the entire process is something out of a science fiction movie. Well, it used to be that way until the practice was perfected and used in actual applications. Genetic engineering made it possible to add new DNA or alter bad ones.

although insect wings are constructed differently than bird wings, they do share a similar overall shape. why?

Answers

These wings share a similar shape due to a process known as convergent evolution. The wings, in this case, are analogous structures that developed independently from one another (aka they do not share a recent common ancestor), but the organisms adapted to a common environment. Simply put, their similar problems lead to similar solutions.

The stress force that causes a mass of rock to pull or twist in opposite directions in called ______

Answers

The force produced when rocks pull in opposite directions is called shearing. Convection currents in the mantle cause tectonic plates to move.Sometimes they slide past each other in opposite directions. This region is called a strike slip fault or transform plate boundary.
Shearing in continuum alludes to the event of a shear strain, which is a distortion of a material substance in which parallel inner surfaces slide past each other. It is instigated by a shear worry in the material. It happens when the material is yielding. The way toward shearing a material may actuate a volumetric strain alongside the shear strain.

Multicellular organisms have many cells. What is the one other characteristic they must have before they can be called multicellular

Answers

The cells must be specialized.

For a single cell or commonly known as unicellular, for them to become a multicellular cell, one must undergo specialization. Multicellular organisms consist more than one cell. It is the opposite of unicellular organisms. Examples of multicellular organisms are animals and plants.

The Answer is: The Cell Must Be Specialized

in a container filled with gas at a constant temperature, the volume is 183 mL and the pressure is at 310 mm Hg. The desired new volume is 90.0 mL. What is the required new pressure? 53 mm Hg 150 mm Hg 330 mm Hg 630 mm Hg

Answers

Answer:

630 mmHg is the required new pressure.

Explanation:

At constant temperature;

Initial volume of the gas,V_1 = 183 mL

Initial pressure exerted by the gas, P_1= 310 mmHg

Final volume of the gas ,V_2= 90.0 mL

Final pressure exerted by the gas ,P_2=?

At constant temperature pressure and volume of the gas varies indirectly.

P_1V_1=P_2V_2 (Boyle's Law)

P_2=(310 mmHg* 183 mL)/(90.0 mL)=630.33 mmhg\approx 630 mmHg

630 mmHg is the required new pressure.
