Phillip was performing a laboratory exercise on how temperature affects a plant's cellular activity. He discovered that when exp

osed to high temperatures (around 50 degrees Celsius), the overall rate of glucose production by photosynthesis decreased.
Which of these conclusions would BEST explain why this occurred?

Hello
We know that biological processes are carried out by organic catalysts known as enzymes. Enzymes are protein molecules that operate over a range of conditions, and a specific set of those conditions are ideal for them. However, in most organisms that are not adapted to withstand high temperatures, the enzymes cannot operate beyond 50 degrees Celsius. This is because their structure starts to deform due to the breakage of bonds within the molecule. The break down is cause by the energy supplied in the form of temperature. An enzyme's structure is essential for it to carry out its task and is made specifically for the molecule it is to act on, the substrate. If the structure is deformed, the enzyme cannot carry out its function. Therefore, the enzymes producing glucose denature and glucose production decreases.

In general, the protein quality in grains would be most improved by the addition of a plant protein rich in ____.?
Anastasy [175]
The appropriate response is lysine. Lysine is a basic amino corrosive. Many individuals realize that few amino acids are known as the "building squares of protein" and are required all together for a colossal number of appropriate inner capacities, including development. 
There are numerous unbelievable L-lysine benefits, from its utilization as a typical treatment for mouth blisters to a potential against nervousness supplement. As is valid with most supplements accessible in supplement shape, L-lysine can be taken orally yet is assimilated best into the body when devoured through nourishment. It's found in substantial sums in different sorts of meat, beans, cheeses, and eggs.

Which of the following levels is the least inclusive, smallest, and most specific of the choices? A. Kingdom B. Order C. Family
Solnce55 [7]
<span>The correct answer is C. Family. That is because the only things smaller than family are genus and species and they are not mentioned here. Life and domain are larger than kingdom and kingdom is larger than phylum. Class and order are smaller than phylum but are larger than family. That's why your correct answer is family.</span>

which of the macromolecules tested in this exercise (proteins, lipids, nucleic acids) were formed by dehydration reactions? expl
aalyn [17]

Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.

As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.

1. Protein structure

  • Amino acid polymers form proteins. There are four different types of proteins, based on structure.
  • The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.
  • The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.
  • A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.
  • The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.

2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.

3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.

Which of the following statements is NOT true of the endocrine system? Most of its components are anatomically connected, like m
katen-ka-za [31]

Answer:

Most of its components are anatomically connected, like most other systems of the body.

Explanation:

The endocrine system takes care of the bodily processes that take place slowly. The nervous system and the endocrine system are independent systems, although they usually work together to help the body function properly.

The endocrine system is made up of glands that make hormones.

The main glands that make up the human endocrine system are the hypothalamus, pituitary, thyroid gland, parathyroid glands, adrenal glands, pineal gland, and reproductive glands, including the ovaries and testes. The pancreas is also part of this system and they are distributed throughout the body, connecting only through the circulatory system.
