Answer:

Antony van Leeuwenhoek1 (Fig. 1) found great joy in God’s smallest creatures. He first discovered protozoans in his youth. The Dutch haberdasher retained a child-like joy of discovery from his youth until his death at age 90. He lived to see tiny microbes though his homemade microscopes. He loved to grind and focus a new lens in order to see the unseen world. Leeuwenhoek spent countless hours grinding tiny lenses and looking through them. This Christian lay biologist even used candlelight to see specimens at night. For Leeuwenhoek, the amazing diversity of tiny life forms revealed under his homemade microscopes glorified God as much as looking at stars through a telescope. Leeuwenhoek was born in South Holland in 1632. As a young adult, he became a cloth merchant (also called a draper, or haberdasher). In 1668, he started his biological study as a hobby after seeing beautiful microscopic pictures while making a visit to London. After years of careful study, Leeuwenhoek (Fig. 2) made the microscope famous. In his lifetime, he became the father of microbiology and opened mankind to the world of microorganisms.

without weathering on the earth's surface, sedimentary rocks would not have been formed

Answer: D. Justice

Explanation:

Science is a field that deals with facts and information based on research and predictions. Justice is the area that is not affected by science. Thus, option D is correct.

Science is involved in many areas of society and has a big impact and influences many elements and components of society. It plays a major role in communication as many inventions and developments in communicating devices are the result of science.

It is primarily concerned with the health and medical field as many scientific inventions and developments are based on experiments and research. it also affects labor as many new technologies and machines have been developed.

Therefore, science does not affect justice.

Answer:

Explanation:

This question is a practical question and would require some sort of experiment. However, let's define what rate of reaction means. The rate of a chemical reaction (in this case fermentation) can be described as the speed at which the reaction occurs; meaning the speed at which product is formed per unit time.

The "claim" in the attachment in the question can be referred to as hypothesis since this question is an experiment. The null hypothesis here will be "the rate of alcoholic fermentation is not affected by the type of sugar used as an energy source".

The "evidence" from the attachment will be result of the experiment conducted which cannot be provided here.

However, the conclusion of this experiment (which also answers the main question; does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy?) should show that the rate of alcoholic fermentation should differ based on the type of sugar used. This is because different enzymes are responsible for the conversion of this disaccharide to the glucose monosaccharide which is what finally undergoes alcoholic fermentation. For example sucrose is broken down into glucose and fructose by sucrase while lactose is broken down into glucose and galactose by the enzyme lactase.

Note that the reaction rate from glucose to produce CO₂ (a product of fermentation) will be the same (regardless of source) but the reaction time from the disaccharide to glucose will be different because of the difference in enzyme and can also be determined by comparing the time to produce the CO₂ by the sugars and the time to produce same amount of CO₂ when given water in the experiment .

During energy transfer, 10% of the energy is transferred to the next trophic level and 90% is lost to the environment. Energy transfers from one trophic level to the next trophic level and not the third trophic level.

Energy transfer is the amount of energy at each trophic level which is transferred to the next trophic level. Energy decreases as it moves through an ecosystem. As little as 10% of the energy at any trophic level is transferred to the next level and the rest is lost largely through metabolic processes as heat energy.

From each trophic level to the next trophic level, about 90% of the starting energy is unavailable to the next trophic level because the energy is used for different processes such as movement, growth, respiration, and reproduction and some energy is lost as heat.

Answer:

saliva

Explanation:

it is a chemical that's helps in digestion

Answer:

Enzymes

Explanation:

The simple answer for that will be that they are not complex organisms. Earthworms are simple organism with the small body,

So as there body is not that big thus they don't need any specialized organ system for the process of respiration. Every organism has the complex systems according to fulfill their needs, and most certainly the skin is very convenient medium for the respiration by the diffusion process.

-------------------------------------------------------------------------------------------------------------

They have a specialized system where it was needed, THE BLOOD CIRCULATION SYSTEM, There body is small but long and need blood to transfer the oxygen to each part of the body. There blood have the haemoglobin(it carries the oxygen), thus it is red just like us.

--------------------------------------------------------------------------------------------------------------

Skin as a respiratory medium, needs to be thin, wet and cover large surface area than volume. The Skin fulfills all these Prerequisites, thus it is a perfect organ for the respiration. Even our respiratory medium which is alveoli is wet, thin and cover REALLY large surface area more than our body. If the skin dries, there will be no diffusion and worm will die due to dessication.

Answer:

Definition. The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.

Explanation:

Answer:

The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time. Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane.

Answer:

Explanation:

Take a look at the traits.

When there are two recessive alles, the recessive trait is inherited. Like in cc.

But if there is a dominate one, per say in lL, the dominant is always inherited.

Answer:

8.Active Transport

9.phospholipid

10.facilitated diffusion

11.osmosis

12.ATP

Explanation:

Active transport is similar to osmosis but it happens with other substances

The phospholipid is shaped like a ball with two legs coming out and the legs connect on both sides of the cell to help protect the membrane and to help provide pathways.

Facilitated diffusion is just what is happening when the material or substance is going through the membrane which is either active or passive.

Osmosis is when the water passes through the membrane from a less concentrated place to a high concentrated place

ATP is energy used to help material or substance through the cell however only certain types of material need the energy to pass through some don't require energy at all

Answer:

If water didn't dissolve most of the substances, humans, as water organisms, with the substances dissolved in the blood and other liquids wouldn't exist.

Explanation:

If water didn't dissolve substances, physical forces, connections between oxygen and hydrogen wouldn't be the same, so it means that the structure of the solid substances in the universe would be completely different. The law of physics would be different, and the whole universal system, as well.

Explanation:

A greenhouse overheating in the summer months has everything to do with engineering design and must be addressed as such. Since the commercial strawberry grower has already established the problem of overheating of the greenhouses, the solution to the problem lies with checking the engineering design of the greenhouses and not in making a scientific inquiry. The problem has been detected and a solution has to be provided by checking the fault in the design that could be causing the overheating.

Botanists trying to know why a newly discovered species of plant only grows in certain areas would need to carry out a scientific investigation/inquiry in order to get answers to their enquiry. Several questions might be raised as to why the growth of the plant is limited to those areas and these can only be answered by conducting scientific investigations.

Answer:

Antigen-presenting cells show digested antigens to T cells through the MHC on their surface, which allows the T cell to “see” the antigen and recognize it as foreign. The connection between the MHC and the receptor on the T cell is the first signal necessary to activate the T cell to respond to a tumor and destroy it.
