Coupled transporters that move solutes in the same direction are called _______.
Answers
The coupled transporters that move solutes in the same direction are called symport.
Three means of transport are present in living cells- diffusion, facilitated diffusion, and active transport.
In facilitated diffusion, the movement of solutes occurs through special transport proteins.
These proteins form channels inside them to facilitate the transport of solutes through them.
Depending upon the direction of movement of solutes, facilitated diffusion is further of three types
Symport - In this case, two solutes move together in the same direction.
Antiport - In the case of antiport two solutes move together in the opposite direction.
Uniport - When a solute moves across the membrane independent of the movement of other solutes it is known as uniport.
The conditions mentioned above are represented in the adjoining diagram.
Hence, the coupled transporters that move solutes in the same direction are called symport.

Which of the following is a characteristic of sponge digestion that distinguishes them from cnidarians?
a) They are not filter feeders.
b) Their digestive process is intracellular.
c) They possess a gastrovascular cavity.
d) They must fully digest a meal and excrete any wastes before ingesting the next meal.
Answers
Option b is correct. Their digestive process is intracellular is a characteristic of sponge digestion that distinguishes them from cnidarians.
Sponge animals are not filter feeders and do not have a gastrovascular cavity like cnidarians. As an alternative, they rely on specialized cells called choanocytes to internalize and digest food particles.
The choanocytes in the sponge engulf the food particles and use enzymes to break them down once they are inside. The nutrients that have been digested are subsequently transferred to other sponge cells for continued usage.
Sponge intracellular digestion is very effective since it allows for the maximal absorption of nutrients from the meal particles. Cnidarians, in contrast, have a gastrovascular cavity that acts as their digestive and circulatory systems.

Answers
Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
What are Autotrophs?
Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.
The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.
Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.
Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.
Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

Which of the following is not true of the carrier molecules involved in facilitated diffusion?
Answers
Carrier proteins are involved in passive transport, moving solute molecules form one side of the membrane to the other. Option (A) is not true. They increase the speed of transport across the membrane.
Facilitated diffusion It is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient
Carrier molecules Carrier proteins move molecules from one side of the membrane to the other side.They do not need energy. They move solutes according to the electrochemical gradient.
The carrier proteins have specific binding sites recognized by the transported molecules. When the proteins and the solutes get together, the carrier proteins suffer a temporal change in their structure. These changes allow the solute passage to the other side of the membrane.
Options,
(A) They increase the speed of transport across the membrane. FALSE
(B) They concentrate solute molecules on one side of the membrane TRUE
(C) They have specific binding sites for the molecules they transport. TRUE
(D) They undergo conformational changes upon binding the solutes. TRUE

What is an ecological footprint and how is it calculated?
Answers
The Ecological Footprint is a combination of all the things we do that require us to draw on natural resources. It includes the impact on our homes (e.g. the oil, gas, and electricity we use), transport (e.g. car, train, and plane trips), food (e.g. land under cultivation and fertilizers), and consumer goods (e.g. fossil fuel energy used to make and transport goods).
Calculation:
Ecological footprints are measured in global hectares (gha) – the amount of bio-productive land and sea available on the planet. We can calculate our footprint by adding up the hectares it takes to grow our food and farm the animals we eat, the hectares our house stands on; the hectares that oil refineries and other energy infrastructure we depend on take up, and the hectares of forest that would be needed to absorb the CO2 emitted by our fuels; a share of the hectares taken up by our roads; and everything else we do that has an impact on the planet’s ecology.

When researchers are measuring plant productivity, they usually harvest and measure above-ground biomass. But with grassland plants, it is common to find that most of an individual's biomass is in its root system. Why don't researchers measure below-ground biomass as well?
Root form is too variable among species--ranging from deep taproots to shallow networks of fine roots.
It's traditional to measure above-ground biomass; in addition, researchers can be a little lazy sometimes.
Above-ground biomass is a better indicator of productivity (NPP).
It's very difficult to measure accurately (roots break, are grafted or entwined with other individuals, or adhere to soil).
Answers
While measuring below-ground biomass is undoubtedly important for a comprehensive understanding of plant productivity, the challenges and limitations associated with its measurement often lead researchers to focus primarily on above-ground biomass as a practical and informative proxy for overall plant productivity in many studies.
Researchers often focus on measuring above-ground biomass when assessing plant productivity for several reasons:
Practicality: Above-ground biomass is generally easier to measure and harvest compared to below-ground biomass. Above-ground parts can be visually assessed, sampled, and harvested without disturbing the soil, whereas measuring below-ground biomass requires destructive sampling methods, such as digging up and washing roots, which can be time-consuming and labor-intensive.
Accessibility: Above-ground biomass is readily accessible and visible, allowing researchers to easily quantify it in the field or laboratory. In contrast, measuring below-ground biomass requires excavation and careful handling of the root system, which may not be feasible in all study settings.
Biomass allocation patterns: While it is true that grassland plants often allocate a significant proportion of their biomass below ground, the allocation patterns can vary depending on various factors such as plant species, environmental conditions, and management practices. However, even with substantial below-ground biomass, the above-ground components (leaves, stems, flowers) remain crucial for processes such as photosynthesis, reproduction, and nutrient acquisition. Therefore, focusing on above-ground biomass still provides valuable insights into plant productivity and ecological functioning.
Indirect assessments: Measuring above-ground biomass can indirectly provide information about below-ground biomass. Above-ground biomass is often positively correlated with below-ground biomass, meaning that an increase or decrease in above-ground biomass generally corresponds to a similar trend below ground. This correlation allows researchers to make reasonable inferences about below-ground biomass based on above-ground measurements, especially when the main objective is to compare productivity among different species, treatments, or ecosystems.

The ___________ is the region of a transcription factor where identical or similar proteins bind together.
A. dimerization domain B. activation domain C. ligand domain D. DNA-binding domain
Answers
The dimerization is the region of a transcription factor where identical or similar proteins bind together.
The dimerization domain is the region of a transcription factor where identical or similar proteins bind together. This domain is crucial for the functioning of the transcription factor as it allows the protein to interact with another protein of the same type, forming a dimer. The dimerization domain is typically made up of alpha helices and allows for the stable association of two protein monomers to form a functional protein complex. The formation of dimers can increase the diversity of transcription factor function as different dimers can have distinct DNA-binding specificities or differential responses to signaling pathways.
Dimerization is an essential step in the regulation of gene expression because it allows for the integration of multiple signals from different signaling pathways. Dimerization is also important for the proper folding of the transcription factor and for targeting it to the correct subcellular location. The dimerization domain can be located anywhere within the protein, depending on the specific transcription factor. It is often located near the DNA-binding domain or the activation domain, which facilitates interactions between different domains of the protein.
