Answer:

Cell wall

Explanation:

Cell wall is a unique structure found only in some specific organisms like plants, bacteria, fungi etc. The cell wall in plants is predominantly made up of a polysaccharide called CELLULOSE. This carbohydrate confers upon the cell "rigidity".

The cell wall is an additive material including the cell membrane that coats the external part of the cell of plants, hence, it gives plant cells their characteristic shape. The cell wall contributes to the overall flexible but rigid shape of the plant cell, protecting the cell against physical or chemical stresses.

The electron transport chain, the NADH and FADH2 produced in the earlier stages are used to generate a large amount of ATP. Overall, cellular respiration is a key process for producing energy that is used by cells to perform a variety of functions.

What is Cellular Respiration?

Cellular respiration is the process by which cells break down glucose and other molecules to produce energy in the form of ATP (adenosine triphosphate). This process occurs in three stages: glycolysis, the Krebs cycle, and the electron transport chain. In glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The link reaction then converts pyruvate to acetyl-CoA, which enters the Krebs cycle. In the Krebs cycle, acetyl-CoA is further broken down, producing ATP, NADH, and FADH2.

Glycolysis: This is the first stage of cellular respiration, which occurs in the cytoplasm of cells.

Link Reaction: The link reaction is the second stage of cellular respiration and occurs in the mitochondria.

Krebs cycle: The Krebs cycle, also known as the citric acid cycle, is the third stage of cellular respiration and occurs in the mitochondrial matrix. It involves the breakdown of acetyl-CoA into carbon dioxide, producing ATP, NADH, and FADH2 in the process.

Electron transport chain: The electron transport chain is the final stage of cellular respiration and occurs in the inner mitochondrial membrane.

Answer

1. To change from Proline to Glycine

Step 1: Change the DNA of proline

Proline has the following four condons: CCG, CCC, CCU, and CCA.

And the Glycine codons are: GGT, GGG, GGA and GGC

So if the codons of Proline can be changed, C to G, we will have CCG, CCC, CCU, and CCA.

Which are the same as the codons of Glycine, when the tRNA translates, these will be amino acids of Glycine.

2. To change Tyrosine to Phenylalanine

The codons of Tyrosine are: UAU, UAC, UAA and UAG

Whereas the codons for Phenylalanine are: UUU, UUC, UUA and UUG

change the A to U in Tyrosine to get Phenylalanine

So the final Tyrosine codons will be: UUU, UUC, UUA and UUG.

1. Wind Reliability

Wind doesn’t generally blow reliably, and turbines usually function at about 30% capacity or so. In the event that the weather is not going to support you, you may wind up without power (or at any rate you’ll need to depend on the electric company to take care of you during those times). Serious storms or high winds may cause harm to your wind turbine, particularly when they are struck by lightning.

2. Wind Turbines Could Be Threat to Wildlife

The edges of wind turbines can actually be unsafe for wildlife, especially birds and other flying creatures that may be in the area. There isn’t really a way to prevent this, but it’s definitely something that you want to make sure that you are aware of being possible consequences that may come up as a result of it.

Answer:

Cells absorb oxygen and release CO2 via the bloodstream. Please find below detailed explanation

Explanation:

Oxygen and carbondioxide (CO2) are the major gaseous substances involved in celluar respiration. Aerobic celluar respiration, which is the process by which cells obtain energy, requires oxygen to occur. The oxygen initially gets breathed in as a constituent of air, which later passes through air sacs and gets attached to hemoglobin in red blood cells. Hemoglobin transports oxygen throughout the cells of the body.

After the process of celluar respiration is done, carbondioxide (CO2) is released back into the bloodstream, which carries it to the lungs. The CO2 is released when we breathe out.

Contralateral means that the crossed extensor reflex takes place on the side of the body that is opposite from the stimulus. Afferent nerve fiber branches travel from the stimulated side of the body to the opposite side of the spinal cord to cause this reflex.

Option 2 is Correct. The six stages of digestion include ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and feces. The mouth is where some chemical digestion happens.

The challenging process of digestion is how food is transformed into nutrients that the body uses for energy, cellular growth, and survival. Making trash for elimination is another step in the digesting process. The body consumes nutrients for energy, growth, and cell repair, and this is accomplished through digestion.

Digestion involves 4 steps:

Answer:

a. when search time is long relative to handling time, predators should be generalists.

Explanation:

In behavioral ecology, the optimal foraging theory can be used to predict animal behavior related to the search for food. Animals need to take different foraging approaches in order to obtain better energy cost benefits. This theory proposes that natural selection chose animals that maximize their adaptive fitness by adopting the better (economically effective) foraging pattern according to its environment. Moreover, animals are regarded as generalists when they are capable of surviving in many different habitat conditions and/or eat different types of foods (omnivores are generally generalist species). In this case, predators with large search times don't have time to choose between different prey, thereby they will be generalists.

Diffusion: the Simple and the Facilitated

Diffusion is the movement of particles down their gradient. A gradient is any imbalance in concentration, and moving down a gradient just means that the particle is trying to be evenly distributed everywhere, like dropping food coloring in water. This is what happened when we made our granola - a bunch of separate ingredients came together and spread out across the whole mixture. We call this evening-out moving “downhill”, and it doesn’t require energy. The molecule most likely to be involved in simple diffusion is water - it can easily pass through cell membranes. When water undergoes simple diffusion, it is known as osmosis.

Movement Across a Membrane and Energy

There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
