The correct order of steps that are involved in photosynthesis are as follows:

Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.  

The complete reaction of photosynthesis is as follows:

The process of photosynthesis gets accomplished in two parts. One is a light-dependent reaction and the other is a light-independent reaction. The sites for both these two processes are different, One occurs in the thylakoid of the chloroplast while the other is in the stroma.

The products formed are also different in both processes. One involves the direct utilization of light from the sun while the other in the presence of indirect sunlight.

Therefore, the correct order of steps that are involved in photosynthesis are well described above.

To determine which country will have the larger population growth, we need to consider the average age and the average number of children per woman in each country.

In Country "A," with an average age of 15, we can expect a larger portion of the population to be in their reproductive years. With an average of 2.1 children per woman, the population is likely to grow due to a higher fertility rate.

In Country "B," with an average age of 30, a significant portion of the population is beyond their reproductive years. This means that there may be a decline in the number of women who can bear children.

Considering these factors, Country "A" is likely to have a larger population growth due to a higher fertility rate and a larger proportion of the population in their reproductive years.

option 4 is the correct answer of the given statement

Answer:

it destroys the active cite of the enzymes and hence decrease the catalase activity.

Explanation:

The open ocean contributes because of its enormous population of phytoplankton, which can produce organic matter through photosynthesis using sunlight and dissolved nutrients. So, all the given statements are correct.

Since there are more phytoplankton due to the size of the ocean, NPP is higher. Phytoplankton make up a sizable portion of the Earth's NPP because they utilise light and dissolved nutrients to create organic matter through photosynthesis. Additionally, because of the open ocean's size, there are larger populations of phytoplankton, which increases the production of organic matter. The primary producers of the ocean are phytoplankton, which use photosynthesis to create enormous amounts of organic matter. The marine ecology as a whole and the maritime food web are both supported by them. Additionally, phytoplankton is crucial to the global carbon cycle because it absorbs a significant amount of carbon dioxide through photosynthesis, which mitigates the effect of greenhouse gases.

The three mechanisms of resistance crop are genetic resistance, tolerance, and avoidance. Genetic resistance is a trait that is naturally present in the crop, which makes it resistant to pests or diseases. Tolerance is the ability of the crop to tolerate pest or disease pressure without suffering major damage or yield loss. Lastly, avoidance is the ability of the crop to reduce the risk of pest or disease pressure by growing in a location or environment that is unfavorable to the pest or disease.

Explanation:

Answer:

Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.

Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.

Energy transfer between trophic levels is inefficient—with a typical efficiency around 10%. This inefficiency limits the length of food chains.

Introduction

Organisms of different species can interact in many ways. They can compete, or they can be symbionts—longterm partners with a close association. Or, of course, they can do what we so often see in nature programs: one of them can eat the other—chomp! That is, they can form one of the links in a food chain.

In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass \rightarrow→right arrow cow \rightarrow→right arrow human. But what if you had lettuce on your hamburger? In that case, you're also part of a food chain that looks like this: lettuce \rightarrow→right arrow human.

As this example illustrates, we can't always fully describe what an organism—such as a human—eats with one linear pathway. For situations like the one above, we may want to use a food web that consists of many intersecting food chains and represents the different things an organism can eat and be eaten by.

In this article, we'll take a closer look at food chains and food webs to see how they represent the flow of energy and nutrients through ecosystems.

Autotrophs vs. heterotrophs

What basic strategies do organisms use to get food? Some organisms, called autotrophs, also known as self-feeders, can make their own food—that is, their own organic compounds—out of simple molecules like carbon dioxide. There are two basic types of autotrophs:

Photoautotrophs, such as plants, use energy from sunlight to make organic compounds—sugars—out of carbon dioxide in photosynthesis. Other examples of photoautotrophs include algae and cyanobacteria.

Chemoautotrophs use energy from chemicals to build organic compounds out of carbon dioxide or similar molecules. This is called chemosynthesis. For instance, there are hydrogen sulfide-oxidizing chemoautotrophic bacteria found in undersea vent communities where no light can reach.

Autotrophs are the foundation of every ecosystem on the planet. That may sound dramatic, but it's no exaggeration! Autotrophs form the base of food chains and food webs, and the energy they capture from light or chemicals sustains all the other organisms in the community. When we're talking about their role in food chains, we can call autotrophs producers.

Heterotrophs, also known as other-feeders, can't capture light or chemical energy to make their own food out of carbon dioxide. Humans are heterotrophs. Instead, heterotrophs get organic molecules by eating other organisms or their byproducts. Animals, fungi, and many bacteria are heterotrophs. When we talk about heterotrophs' role in food chains, we can call them consumers. As we'll see shortly, there are many different kinds of consumers with different ecological roles, from plant-eating insects to meat-eating animals to fungi that feed on debris and wastes.

The best description of originality is having a low probability, unique, option D is correct.

Originality refers to the quality of being novel and distinctive, and it implies that something is not derived from anything else. The more unique and uncommon an idea, creation, or expression is, the more original it is deemed to be. Originality can be measured by the probability of its occurrence.

The lower the probability of an idea or creation being generated, the more original it is. A highly original idea is not only new but also unexpected and unconventional, which makes it stand out from the norm. Originality is highly valued in fields such as art, literature, science, and technology, as it contributes to the advancement of knowledge and understanding, option D is correct.

Answer:

C. The mRNA will be changed from U-A-C to U-A-G during transcription.

Explanation:

Transcription is the process where the mRNA strand is formed, using a DNA strand as a template strand.

The bases on an mRNA are adenine [A], uracil [U], guanine [G] and cytosine [C], where adenine is complementary to uracil and guanine is complementary to cytosine.

[Translation is the process where a polypeptide chain- a sequence of amino acids, is formed. tRNA molecules carry specific amino acids and bind to the codon on the mRNA which is complementary to the anticodon on the tRNA. Thus option A and D is wrong.]

[Option B is wrong because the bases are not complementary.]
