Describe two practical uses for an artificial chemical which behaves like chlorophyll.​

Any substance that has enhanced reactivity, or altered properties in the presence of light is said to be photoreactive. For example, a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. Photoreactive substances can either be natural, such as chlorophyll, or entirely man-made in the case of a photovoltaic cell.

An object has a kinetic energy of 25 J and a mass of 34 kg. How fast is the object moving?
Andreyy89
Kinetic energy is the energy possessed by an object with mass when in motion. It is calculates by 1/2 the product of the mass of the object and the square of its velocity.

KE = 1/2 (mv^2)
25 = 1/2 (34)(v^2)
v = 1.21 m/s

You know that the narrow-sense heritability of milk production in Ayrshire cattle is 0.587. You perform an experiment where you
Paha777 [63]

Answer:

Explanation:

Narrow sense heritability - h​​​​2

​​​​​​selection differential - S

Selection differential is calculated from the difference between the population average and the parental population.

Breeder's equation:

Response to selection - R = h​​​​​​2S

Mean milk production of 10% cows for experiment = 8.9L/hr

Mean milk production of parental population = 5.1L/hr

Selection differential S= 8.9 - 5.1 = 3.8 L/hr

Response to selection = 0.587 × 3.8 = 2.23

What is the relationship between Endomembrane System, Insulin and Insulin Receptor, activation by phosphorylation, membrane-boun
mars1129 [50]

Answer:

The relationship between endomembrane system, insulin and insulin receptor, activation by phosphorylation, membrane-bound polyribosomes, and glucose transport channels is the eukariotic cell, because within it, they work together with the organelles to modify, summarize and transport lipids and proteins from the gut and absorb nutrients.

Explanation:

The Endomembrane system varies from membranes and organelles, but basically, it is structured by the nuclear envelope and lysosomes, the plasma membrane and several cytoplasmic organelles, as the ER, the Golgi apparatus, secretory granules, vesicles, lysosomes, endosomes, and the endoplasmic reticulum all working together to transfer, modify and package lipids and proteins macromoecules to the eukaryotic cell, from one part of it  to another, and from in to the outside of it also.

The membrane bound polyribosomes are attached to the cell endoplasmic reticulum. The bound ribosomes, used within the cell membrane or expelled from the cell by exocytosis, will produce insulin and they will become membrane bound to control the intake, protein modifications, fusion lipids and sugar breakdown. The insulin is a membrane bound polyribosomes protein synthesized in the ER, which travels along the endomembrane system. This hormone controls glucose and lipid metabolism  or energy function, if glucose level is high, insulin synthesis is activated.  

Synthesized and traveling through the endomembrane system, the insulin gets to its receptor called tyrosine kinase and activates it, phosphorylating and recruiting different substrate adaptors.

 The brand new insulin polypeptide chains go directly into the endoplasmic reticulum by the ribosome and then transported to where they are needed as insulin regulates sugar uptake into adipose tissue and skeletal muscle through glucose transport channels or glucose transporters GLUT4 within vesicles, which are directed to the plasma membrane, this is also the gut and nutrient absorption.

Humans and hogs have differences in only 1 out of the 51 amino acids in their insulin proteins. Hogs and guinea pigs have differ
balu736 [363]

Humans are more closely related to hogs than hogs are to guinea pigs.

Explanation:

The difference in the amino acid sequence of a protein is used to know the  relation between organism i.e. how closely they are related.

It is known that proteins are the result of DNA sequence ie genes of the organism.

The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.

The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having  a difference of 17 amino acids so it is expected to be distantly related.

These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.

Predict how the sympathetic reflexes controlling blood vessels would respond to a sudden decrease in blood pressure
Goryan [66]
<span>Baroreceptors are special receptors that detect changes in your blood pressure. Important baroreceptors are found in the aorta and the carotid sinus. If the blood pressure within the aorta or carotid sinus increases, the walls of the arteries stretch and stimulate increased activity within the baroreceptors.</span>
