Chloe is developing a model of photosynthesis. The first part of the model is shown below. Which would be the MOST useful next step for Chloe to develop the photosynthesis model further?
A.) Extend the lines for sunlight so that they pass through the autotroph.
B.)Represent a chemical reaction in the autotroph that produces high-energy carbohydrates.
C.)Represent a chemical reaction in the autotroph that produces high-energy proteins.
D.)Draw a circle to represent a heterotroph, and draw a line to connect it to the autotroph.
Answers
Answer:
B, because logically, Photosynthesis takes sunlight (light energy), water(h20), and carbon dioxide( c02), and converts it into sugars (glucose / carbohydrates), and oxygen(o2). As D would be less necessary because humans and animals are not autotrophs and do not undergo photosynthesis to produce their own food. it is not the most necessary thing to label.

If the primary structure of the protein is changed, what will happen to a) the secondary structure and b) the tertiary structure of the protein
Answers
Answer:
The primary structure refers to the amino acids in a protein molecule. Changing one of the amino acids can affect whether a protein will form alpha helices or beta sheets during folding. If alpha helices and beta sheets are changed, the interactions between amino acids along the length of the protein will be altered as well, leading to changes in the final 3D structure of a protein experiencing a primary structure change.
Explanation:
a) The secondary structure may be affected, and some secondary structural elements may be lost or altered.
b) The tertiary structure will likely be disrupted or changed, affecting the overall folding and 3D conformation.
Protein primary structure refers to changes in the linear sequence of amino acids that make up the protein chain. Because it dictates amino acid interactions and bonding, the fundamental structure is essential for secondary and tertiary structure creation.
a) Primary structural changes impact secondary structure. Hydrogen bonding between amino acids forms secondary structures like alpha-helices and beta-sheets. These relationships may be interrupted if the basic structure is changed, causing secondary structural components to lose or distort.
b) Primary structural changes can also affect tertiary structure. The protein molecule's 3D tertiary structure is governed by hydrophobic interactions, disulfide bonds, and van der Waals forces. Changes in the fundamental structure may disrupt these connections, leading the protein to misfold or lose its 3D shape.
Any protein primary structure mutation can cascade into higher-order structures, causing loss of function or altered biological activity.

Wetlands help slow the process of erosion by trapping sediments. Please select the best answer from the choices provided T F.
Answers
Wetlands help slow the process of erosion by trapping sediments. This statement is true.
What do you mean by Wetlands?Wetlands are the areas where the soil contains an excess amount of water in it.
Wetlands generally function as normal sponges and gradually release the water outside in the soil. And due to this excess amount of water, soil gains its properties by trapping sediments that lead to the slow down of the erosion process.
Therefore, Wetlands help slow the process of erosion by trapping sediments.

The food web shows how organisms are interconnected in a feeding relationship and how changes in one organism's population affect other organisms.
What is feeding relationship?A feeding relationship shows how two or more organisms which interact together to obtain food are affected by changes that occur to either of the organisms in the relationship.
An example of a feeding relationship is one between the phytoplankton, the shrimp, the crab, the octopus, and the sea otter.
Phytoplankton are producersShrimp eat phytoplankton Crabs eat shrimps Octopus eat crabsSea otters eat octopusIf the crab population increased, the octopus population will increase due to availability of more food.
The sea otter population will increase if the crab population increased due to increase of individuals in the food chain.
The carrying capacity will decrease if all of the producers in the food web died because their will be no food to support the organisms in the food web.
The total energy availability in the ecosystem will increase if sea urchin shrimp, and baleen whales increase because increase in organisms.
The carrying capacity of octopus in the ecosystem will increase if more shrimp move into the ecosystem.

3 examples of inherited variation in dragon fruit
Answers
Answer:
Dragon fruit, a kind of fruit belonging to Hylocereus spp., has brought about interest in China not only due to its important economic value with high contents of nutrients, but also due to the striking tolerance to drought stress. Fifteen morphological traits and 111 Inter-Simple Sequence Repeat (ISSR) markers generated from 16 primers were firstly employed to discriminate 50 accessions recently selected in China, as well as to evaluate their genetic relatedness. According to univariate statistical analysis of morphological traits, high variations were observed between or/and within the wild and cultivated lines. The dendrogram of 50 accessions was constructed based on morphological traits. Taking 7.50 as a threshold, three major clusters could be observed, i.e. the first included nine genotypes, which mainly belonged to wild accessions; the second clusters standing for the red pulp genotypes; the third consisting of the white pulp accessions. Each ISSR primer generated 4–10 obvious DNA bands ranging from 100 bp to 1500 bp, with the average of 6.9 per primer.
Dragon Fruit is found in Central America, Northern South America and some parts of Mexico.
There are three different types of Dragon Fruit which are its inherited variations.
Hylocereus undatus or piyata blanca which is pink or red skin having white flesh and black seeds.
Hylocereus costaricensis or piyata roja which is pink or red skin having red flesh and black seeds.

Other than carbon dioxide name two carbon compounds found in plants.
Answers
Answer:
See below.
Explanation:
Other than Carbon Dioxide (CO₂), two carbon compounds found in plants are :-
Glucose (C₆H₁₂O₆)Pyruvic Acid (C₃H₄O₃)The Calvin cycle, C3 pathway, or 3-phosphoglycerate photosynthesis are all names for the method by which plants fix carbon. PGA is a 3-carbon molecule.
What is the function of carbon in plants?The reasoning is simple Plants require atmospheric carbon dioxide to make food, and as a result of increased CO2 emissions from industry and autos, some crops and trees will grow bigger and faster.
Carbon is continuously exchanged between plants and the atmosphere. During photosynthesis, plants take up carbon dioxide, much of which is then stored in their roots in grasslands, and forests.
Therefore, Glucose and phosphoglycerate are the two carbon compounds found in plants.
