In systemic acquired resistance, which molecule is transported throughout the plant?.

Answers

Answer 1

Answer:

Answer:

Salicylic acid

Explanation:

Salicylic acid is a plant hormone that is essential for a variety of biological parameters, including defence for a plant. There have been many advances in SA-mediated biosynthesis, transport, perception, and signaling over the past two decades. These data show that AS is crucial in local and systemic defensive responses. One such SA-dependent response is systemic acquired resistance (SAR). is a long-distance communication system that provides broad spectrum and long-term resistance to secondary infections throughout the plant. Because of this distinctive property, SAR is a highly sought after trait in agricultural production.This article describes recent developments of the SA function in SAR and analyzes how it connects to other SAR inductors.

What term is defined as the ability to do work

Answers

Good Morning! In the understanding of biological sciences in general, the ability to perform work, that is, to effect movements, pratices or even functions without macro representation, for a result, is called "energy", and can have different sources, forms and origins. Thus, it is possible to affirm that: energy is the ability to do work. Hope this helps. Let me know if you need additional help!

In Physics, the term that represents the ability to do work is energy.

Physics defines the term you're referring to as energy. Energy is the ability to do work. It is the capacity of a system to perform work or to transfer heat as a result of motion or position.

The Krebs cycle takes place within the:A. mitochondria
B. lysosome
C. vacuole
D. cytoplasm

Answers

Answer: A. mitochondria

Explanation:

The Krebs cycle is the set of reactions that drives to the complete oxidation of glucose. This occurs in the matrix of eukaryote mitochondria and the prokaryotyc cytoplasm. The main reagents of the Krebs cycle are acetate in the form of acetyl-CoA, water, and electron carriers. The main reagents of the Krebs cycle are acetate in the form of acetyl-CoA, water, and electron carriers. Reactions are catalyzed by enzymes where decarboxylases stand out (decarboxylation catalysts) and dehydrogenases (oxidation-reduction catalysts) leading to the formation of NADH).

The Krebs cycle occurs in the mitochondrial matrix (mitochondria) and generates a pool of chemical energy (ATP, NADH, and FADH2) from the oxidation of pyruvate, the end product of glycolysis.

Which phase of cardiac action potential is caused by closure of the fast sodium channels? phase 0 phase 1 phase 2 phase 3?

Answers

Answer: phase 1

A cardiac action potential can be divided into phase 0-4. In phase 0, the sodium channel is opened and sodium will come into the cell which causes a rapid depolarization. In phase 1, the fast sodium channel is closed and K+ channel starts to be opened which makes a small repolarization.

Choose the correct answer. -lactose is Glcα1-4Glc -maltose is Glcα1-4Glc -sucrose is Glcα1-2Glc -cellobiose is Galβ1-4Glc

Answers

The answer is lactose is Glcα1-4Glc.

Lactose is a disaccharide sugar derived from galactose (Glca) and glucose (Glc) which form a β-1-4 glycosidic linkage (Glca1-4Glc).
