Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.Body structures can change according to the actions of the organism.have an innate tendency toward complexity and perfection. The actions of organisms as they use or fail to use body structures.
Answer:
D. Because science only uses facts that are proven 100% true through the use of variables.
Explanation:
All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is proven 100% true through the use of variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.
Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of variables.
Hope it helps!
The flowers will not grow as well because bacteria are needed to fix nitrogen
Numerous plants have symbiotic interactions with bacteria, which provide them with essential nutrients like nitrates. His flowers' growth will be limited and they can even perish if all the bacteria are gone.
<h3>What are Good bacterias ?</h3>
Friendly bacteria or good bacteria can help plants grow by helping the plants to obtain nutrients such as phosphorous and nitrogen, or by defending the plants from other microbes that can make them sick.
- Beneficial good bacteria for plants produce chemicals and hormones that stimulate growth. Beneficial bacteria help prevent infections from pathogens by coating the root surfaces and triggering svstemic disease resistance.
- By this way the use of bacteria killing chemical will all kill good bacteria which helps plant growth.

Answer:
The increase in the amount of carbon dioxide in in blood will lead to respiratory acidosis
Explanation:
Carbon dioxide in its normal level between 38 to 42 mm Hg plays vital roles in the human body like regulating the PH of the human blood, breathing regulation and other things. If the amount of carbon dioxide is high more than the range level, it will cause what is called respiratory acidosis.
Respiratory acidosis is a situation in cause by decrease in ventilation i.e Oxygen level leading to increase in carbon dioxide and drop in PH level of the blood.
