Answer:

Jean-Baptiste de Lamarck

Explanation:

His two principles were "use and disuse" and "inheritance of acquired characteristics." The latter is what the statement is referring to.

Answer:

Lamarck

In the case of a giraffe, Lamarck believed that giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks as long as they could. In doing so, Lamarck believed that each generation would grow slightly longer necks and pass that trait onto their offspring.Jan. 16, 2018

Glycolysis is an example of a metabolic pathway that is utilized by all human body tissues. Other pathways are much more promine
AnnyKZ [126]

Answer:

1. Liver

2. Liver and Kidneys

3. Mitochondria

4. Lumen of the small intestines

5. Liver

Explanation:

1. Glucose is phosphorylated into glucose-6-phosphate which is the first step of both glycogen synthesis and glycolysis, this process occurs in the liver

2.   Glucose 6-phosphate is a product of a process named gluconeogenesis which occurs in the liver it serves as a substrate for glucose-6-phosphatase in the liver.

3. Creatinine kinase is an enzyme that catalyzes the phosphorylation of creatine. In regeneration process of ATP, creatine phosphate transfers a high-energy phosphate to ADP which produces ATP and creatine

4. Initially lipase digestion lipase digestion happens in the small intestine where the bile salts reduce the surface tension of the fat droplets allowing the lipases to attack the triglyceride molecules. These molecules are taken up into the epithelial cells that line the intestinal wall, where they are resynthesized into triglyceride

5. The job of the liver is to produce ketone bodies. If the liver had this enzyme, the ketone bodies it produces would be immediately broken down by the liver before they are released, thereofore, no release of ketone bodies into the bloodstream

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area
sashaice [31]

<u>Answer</u>:- Active transport

<u>Explanation</u>:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from <em>high concetration to low concentration.</em>

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from <em>low concentration to high concentration.</em>

<em>The active transport is of two types:</em>

1. <em>Primary active transport-</em> in this type of transport <em>ATP</em> is used as an energy source to move the substances against the concentration gradient.

2.<em>Secondary active transport</em> - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.


  • The membrane proteins that are associated with active transport are called as <em>carrier proteins</em>. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the <em>active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.</em>
