Answer:

The correct option is C

Explanation:

The central dogma involves conversion of DNA to protein. The DNA either undergoes transcription to form RNA or replication to form a new DNA. When transcription occurs, RNA is formed which can then be translated into protein. Consider the illustration below

DNA ⇒ RNA ⇒ Protein

There are three types of RNA

Of these three RNAs, the mRNA is the one translated into protein with the aid of the remaining two.

From the above, it can be deduced that DNA cannot be directly converted into protein.

The mode of transfer that does not occur in the process of genetic expression in cells is directly from DNA to protein. Information first passes from DNA to RNA, and then from RNA to protein.

In the process of genetic expression in cells, the mode of transfer that does not occur is DNA ---> Protein.

The usual sequence of information transfer is from DNA to RNA, and then from RNA to protein, a process known as the Central Dogma of Molecular Biology. The DNA is transcribed into messenger RNA (mRNA) in a process called transcription. The mRNA is then translated into protein in a process called translation.

Function and structure. Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway.

The enzyme has an active site. It catalyzes the substrate into the product. The more the substrate is compatible with the enzyme, the more product formation is seen.

The enzyme is proteinaceous, except ribozyme. Ribozyme is an RNA molecule that can catalyze the reaction. Except the protein part of the enzyme, they consist of organic and inorganic molecules such as magnesium, zinc, etc.

These inorganic molecules are present near the active site of the enzyme and help in catalysis. The active site of an enzyme is attached to a substrate. The substrate forms a noncovalent bond with the active site and is converted into product.

The more efficient the catalysis, the better the enzyme substrate binding. The substrate should be compatible with the active site. Apart from the active site, some enzymes have an allosteric site. It is different from an active site. Allosteric regulators bind at this site and regulate the enzyme either positively or negatively.

Hence, the function depends on the binding site and the substrate.

2. Directed pressure

2.) directed pressure

Gneiss is a foliated metamorphic rock that forms under conditions of directed pressure.  This pressure flattens and elongates the rock in the direction of the greatest pressure, causing the minerals within the rock to realign and form distinct bands.

Foliation is created through a process of differential pressure where mineral grains break, migrate, and recrystallize due to the uneven forces exerted within the Earth's crust, often along the boundaries of tectonic plates where collision or subduction is occurring.  Non-foliated metamorphic rocks, such as quartzite and marble, can also form under directed pressure but do not show the characteristic banding seen in foliated rocks like gneiss.

The reason Common names are not useful to Biologists is that they can apply to more than one animal.

1. An infinitely dense atom of matter explodes, releasing all matter in the known universe.

2. This matter clumps together forming rocks and dust; that which doesnt compact remains as gas.

3. The rocks and dust are pulled in to each other by their own gravity. These clumps get bigger and bigger, and form planets.

4. Gas and dust clouds, better known as nebulae, (sing. nebula) begin to react, clump together and generate heat. Stars are formed out of these nebulae (unsure of the process).

5. The stars, with their powerful gravitational pulls, drag in planets to form solar systems. This happens on a larger scale as well, as groups of millions of stars are formed into galaxies, huge swirling discs containing millions of stars each.

That's where we are today.

Answer: d. All of the above are true.

If an organism lives currently in a specific environment, it does not mean that it cannot spread further on due to changes. A good example are invasive species that under human influence have spread in many areas of the globe where they have had a negative impact on native ecosystems.

Our planet is a complex system with many interconnected parts. Thus, what happens in one region can affect many other regions as both air and water move globally. The same is true for locally released carbon dioxide that will result in a local increase in air temperature. However, this can change the global air currents or [tex]CO_{2}[/tex] itself can move and accumulate in other regions.

Local environmental changes can have global effects due to the movement of organisms, the transfer of air and water, and the increase of carbon dioxide levels. All of these factors can impact global climates, ecosystems and temperatures. Thus, the correct answer is option D - all are true.

Local environmental changes can indeed have global effects in various ways. For instance, organisms moving from one environment to another, like invasive species, can disrupt local ecosystems and cause a chain reaction impacting the global ecological balance. Similarly, air and water continually move from region to region, carrying pollutants or heat, influencing global climates.

Moreover, an increase in carbon dioxide in a specific location can result in increased temperatures in other parts of the world, because greenhouse gases like carbon dioxide trap heat in the atmosphere, contributing to global warming. In conclusion, all of the above statements are true and demonstrate how local changes can have far-reaching global ramifications, meaning the correct answer is D.

Ecosystems can lose equilibrium due to catastrophic natural events, human-induced disruptions, and the loss of keystone species. These events can overwhelm the ecosystem's resistance and resilience, leading to irreversible changes or total collapse.

An ecosystem can lose its equilibrium due to several factors, both natural and human-induced. Natural events such as bushfires, droughts, floods, and volcanic eruptions can cause temporary or long-term disruptions in an ecosystem, impacting its health and leading to possible ecosystem collapse or the need for ecological succession. Human impacts, including the introduction of toxic substances like DDT or excessive fertilizers, can lead to the depletion of key species and alter nutrient cycles and energy flows, which are central to maintaining ecosystem equilibrium. Additionally, the loss of keystone species can set off an extinction cascade, fundamentally changing the ecosystem's composition and function.

It's essential to understand the concepts of resistance and resilience in ecosystems, which describe an ecosystem's ability to withstand disturbances and bounce back to a state of equilibrium, respectively. When human actions such as pollution, overfishing, or habitat destruction overwhelm an ecosystem's resilience, it can cripple the ecosystem's ability to return to its original state, potentially leading to irreversible changes or complete destruction.

Plants, help water get into the atmosphere through a process called transpiration. After absorbing water from the ground, plants “sweat” water vapor through their leaves to stay cool. Water can also get into the atmosphere from snow and ice.

This is called Thermal Expansion.

Answer: can be almost any size

Explanation: Plants are extraordinary organisms that come in a variety of shapes and sizes. The smallest is the watermeal (Wolffia globosa). With sizes of approximately 2 millimeters (0.079 in), it is also the smallest flowering plant in the world. One of the largest are the sequoia with heights of 70-85 meters and ages of over 3000 years old.

Plants are usually divided into two groups depending if they produce seeds or not. Thus, the three group title is unsuitable. As shown above, plants can reach extremely large sizes so the second title is unsuitable too.

All multicellular organisms contain specialized tissues, not only plants. Plants use active transport too and do not rely solely on diffusion. The last tile is also unsuitable as some plants do have true stems and leaves.

The best title for Paulo's presentation would be "How Plants Differ". This is because it is the most general title that encompasses all of the information in his notes. The other options are either too specific or not specific enough.

How Plants Differ is a good title because it covers all of the following points:

Plants can be divided into three groups: non-vascular, vascular, and seed-bearing.

Plants can be small or large, depending on the species.

Plants have specialized tissues, but they also use other mechanisms, such as active transport.

Some plants have true stems and leaves, while others do not.

The other options are not as good because they do not cover all of these points. For example, "Can Be Almost Any Size" is too specific because it only covers one of the points (that plants can be small or large). "How Plants Work" is not specific enough because it could cover a wide range of topics, not just the characteristics of plants.

Therefore, the best title for Paulo's presentation is "How Plants Differ".

In the deep ocean, currents are what sea creatures use to travel at a faster and easier rate. If these currents decrease than it would be hard for them to travel. For example, if a sea turtle needed to lay her eggs, but there was no current, she might not get to land on time before she has to lay them.

Currents such as the EAC enable organisms or creatures to travel throughout, much the same as in Finding Nemo.

Organism:  

An individual is any living thing or organism. Individuals do not breed with individuals from other groups. Animals, unlike plants, tend to be very definite with this term because some plants can cross-breed with other fertile plants.

In the diagram above, you will notice that Gill, the goldfish, is interacting with its environment, and will only crossbreed with other gold fishes just like her.

Population:  

A group of individuals of a given species that live in a specific geographic area at a given time. (example is Gill and his family and friends and other fishes of Gill’s species) Note that populations include individuals of the same species, but may have different genetic makeup such as hair/eye/skin colour and size between themselves and other populations.

Community:  

This includes all the populations in a specific area at a given time. A community includes populations of organisms of different species. In the diagram above, note how populations of gold fishes, salmons, crabs and herrings coexist in a defined location. A great community usually includes biodiversity.

Ecosystem:  

As explained in the pages earlier, ecosystems include more than a community of living organisms (biotic) interacting with the environment (abiotic). At this level note how they depend on other abiotic factors such as rocks, water, air and temp

Biome:  

A biome, in simple terms, is a set of ecosystems sharing similar characteristics with their abiotic factors adapted to their environments.

Biosphere:  

When we consider all the different biomes, each blending into the other, with all humans living in many different geographic areas, we form a huge community of humans, animals and plants, and micro-organisms in their defined habitats. A biosphere is the sum of all the ecosystems established on planet Earth. It is the living (and decaying) component of the earth system

The functions that will be most immediately affected by a reduction in water uptake by roots would be Photosynthesis and Sunlight Absorption.

Water constitutes approximately 90% of the plant weight, acting in practically all physiological and biochemical processes. It serves as a

Enter cells and move through the plant. It also has an important role in the thermal regulation of the plant, acting both in cooling and in the maintenance and distribution of heat. If a plant's soil has too much water, the roots can rot and the species doesn't get enough oxygen from the soil.

With this information, we can conclude that water is used for chemical and biochemical processes supporting metabolism, which uses sunlight to split the content into hydrogen and oxygen.

A reduction in water uptake by the roots would immediately affect the photosynthesis process. This is due to water’s crucial role in photosynthesis where plants turn sunlight into chemical energy. Other functions like disease resistance, seed dispersal and sunlight absorption won't show immediate effects.

The function that would be most immediately affected by a reduction in water uptake by roots is Photosynthesis. This is because water is a crucial component in the photosynthesis process, where plants convert sunlight into chemical energy. By reducing the water uptake, the plant would not have enough water to carry out photosynthesis efficiently, thus affecting the plant's energy production and growth.

Disease resistance, seed dispersal, and sunlight absorption would not be immediately affected because these functions either don't rely directly on the quantity of water available, like photosynthesis does, or take a longer time to show effects of reduced water uptake.
