  <span>The cells all have different qualities. 
A plant cell will have a cell wall (the others don't have these) and so it will be kept in a rigid shape, unlike the others which are free to be blobby. Inside a plant cell, there is also a vacuole containing cell sap. The others don't have this. Plant cells also have chloroplasts, which look similar to mitochondria on a diagram. Chloroplasts contain chlorophyll, and this is used for photosynthesis. </span><span>

Describe how temperatures above 35 C most likely affect the structure and function of the starch synthase in the particular stra
arlik [135]

Answer:

- It is very likely that temperatures above 35°C will change the structural configuration of the enzyme, denaturing it and preventing it from performing its function.

- According to the information, the most probable consequences for this rice crop is that its starch content will be lower, compared to crops grown at optimal temperatures.

Explanation:

<u>The full question includes this statement</u>:

<em>A rice grain is a fruit that encloses a seed. Most of the dry mass of a rice grain is starch. In rice plants,  starch is produced by hydrolyzing sucrose and then linking the released glucose molecules together into  starch . The optimal temperature range for starch synthase activity in a particular strain of rice  is 27°C - 30°C. The optimal temperature range for sucrose synthase in the strain is 30°C - 35°C.</em>

One of the factors affecting enzyme activity is temperature, according to which an enzyme can make a reaction faster, slower or inhibit the activity of that enzyme.

For a grain of rice to acquire its starch content, the activity of two enzymes is required, sucrose synthase - to obtain glucose from sucrose - and starch synthase, to polymerize glucose into starch (see image).

<h3>In this case, how temperatures above 35°C most likely affect the structure and function of the starch synthase?</h3>

The temperature of 35°C is far above the optimum temperature required for the enzyme to act, so it is possible that a change in the structure of the enzyme will occur or that it will be denatured, preventing the starch synthase from performing its function. One consequence of this is a lower starch synthesis.

<h3>When the average temperature in the growing season is 33°C, what can be predicted about the consequences on the starch content in mature rice grains?</h3>

A temperature of 33°C is outside the range of starch synthase activity -even though it is optimal for sucrose synthase- which would decrease starch synthesis and, because of this, the rice grains in this crop would have less starch content.

Which description properly describes the plant structures involved in photosynthesis? Stomata take in water, sunlight, and carbo
erma4kov [3.2K]
The correct answer is that "xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight." The xylem is a vascular structure in plants that transport water, the phloem is another vascular structure in plants that transport nutrients. The stomata (singular; stoma) is the one responsible for the plants' gas exchange (takes in carbon dioxide, releases oxygen). The chlorophyll is what makes the green pigment of the leaves and mostly because of the presence of chloroplasts, the organelle in plant cells responsible for photosynthesis.

How do sodium and potassium leak channels play a role in the development of the negative membrane potential of the axolemma (pla
kirza4 [7]
The plasma membrane of axon is called axolemma. The potassium and sodium leak channels leak the sodium and potassium ions inside the cell respectively. The leak channels provide the constant movement of ions across the membrane. Potassium and sodium ions are positively charged, thus entry of positively charged ions inside the cell makes the cell more positively charged than the environment outside the cell. The environment outside the cell becomes more negatively charged. This leads in the negative membrane potential of axolemma.

Oxana [17]

Answer:

Penguins in general are distributed close to each other to be able to withstand the extreme cold, characteristic of the ecosystems they inhabit. They also group together to incubate their eggs.

They perform a series of coordinated movements that help them fight low temperatures, being careful to drop the egg.
