g About how much of the energy in the producers of an ecosystem will be available to secondary consumers in this ecosystem
Answer:
10 %.
Explanation:
Only 10 % of energy in the producers of an ecosystem will be available to secondary consumers of that ecosystem while the remaining 90 % will be lost and releases in the atmosphere in the form of heat energy. In each trophic level, only 10 % of the total biomass is transferred from one trophic level to another trophic level while the remaining biomass is released in the form of heat. If the producers has 1000 calories of energy, only 100 calories will be transferred to the primary consumer.

5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74 frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13 frequencies of dark-colored mice ≅ 0.873)
p² ≅ 0.02 q² ≅ 0.74 2pq ≅ 0.244)
q² = 0.13 p² = 0.4 2pq = 0.465) The dark-colored fur seems to have the greatest overall selective advantage
6) Dark lava changed the color of the substrate, from light to dark.
7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.
8) To see if the mice population is evolving. If it is, there will be a change in the allelic and genotypic frequencies over the years. If it is not evolving, the frequencies will keep equal through the years.

Explanation:
Receptor binding motifs such as RGD have highly selective recognition for cell adhesion. Outline a strategy for incorporating a cell adhesive recognition domain to a biomaterial. Address the problems surrounding domain quantity, type, and affinity in your discussion.
Answer:
Explanation:
RGD stands for Arginine Glycine Aspartate and is a three-amino-acid peptide. It is the most extensively utilized adhesive peptide for adhering diverse cell types to a variety of biomaterials. Integrins, fibrinogen, osteopontin, fibronectin, and bone sialoprotein, as well as collagens and laminins, all include an RGD primary binding domain. As a result, the synthetic (artificial) peptide RGD may bind to a wide range of integrin types. The artificial RGD retains its functioning through the sterilizing and processing processes of biomaterial creation because of its recognition advantage. This feature denotes the immune reactivity and pathogen transmission during xenograft.
Affinity can be modulated by the conformation of artificial RGD. The efficacy of RGD is also determined by the in vitro deposition of cells on the surface of the material sample.
The molecular processes unravel its effectiveness throughout its use as a scaffold foundation in in-vivo models. The fact that artificial RGD cannot work well in isolation is now a major aspect that defines its activity.
It has been discovered that cells release a variety of integrin-binding proteins that are more effective in activating integrin signalling than pure RGD. As a result, most biomaterials will bind and adsorb these proteins rather than RGD. As a result, a serum-free medium is employed in the majority of in vitro research.
As a result, biomaterials are supplied with RGD as well as quasi polymers such as polyethylene glycol to reduce the variance produced by native proteins. The addition of additional amino acids to RGD based on natural sequences can increase its biological activity, which can aid in the development of new tissues and the stimulation of cellular responses and signalling.
The amino terminal endpoint of the peptide, as well as the carboxyl group of the material surface, establish a covalent connection, which binds the peptide to just the surface of its biomaterial. Cell adhesion biomaterials are made from a variety of cell adhesion materials, including poly-L-lysine, mussels adhesive protein (MAP), and outer membrane (extracellular matrix) proteins.
Because MAPS are high in Dihydroxyphenylalanine and lysine, RGD is coupled with either of these to boost its cell adhesion capability. As a result, they can also aid in the attachment to damp or moist surfaces. It may also firmly adhere to glass, metals, and plastics. The addition of thiol groups to a peptide can also aid in its orientation and boost its stability.
The gap and density of this peptide sequence and structure on the biomaterial surface may be adjusted using a micro and nanotechnology (nanoscale patterning) method, which also improves ligand binding accuracy. Cellular reactions and cell activity are also under its control. Integrin receptors have been shown to be between 9 - 12 nm in size, therefore nanoscale surface patterning is crucial.
As a result, the above methods serve as a strategy for incorporating a cell adhesion recognition domain into a biomaterial while taking into account all of the technical intervention affecting its quantity, type, and affinity to the top layer for cell adhesion as a functioning tissue rather than a monolayer.

Answer:
the answer is A and D
Explanation:
because yes
Cellular respiration and photosynthesis are significant carbon cycle processes. The processes via which carbon is recycled in the biosphere are known as the carbon cycle. Thus, option A, D is correct.
What is the effect of carbon dioxide to the atmosphere?
Unlike cellular respiration, which releases carbon dioxide into the environment, photosynthesis eliminates carbon dioxide from the atmosphere.
When fossil fuels are burned, a greenhouse gas called carbon dioxide is massively released into the atmosphere. Greenhouse gases, which trap heat in our atmosphere, are to blame for global warming.
Therefore, Photosynthesis and cellular respiration have opposite effects on carbon dioxide levels and the burning of fossil fuels adds carbon dioxide to the atmosphere.

A bear walks into the room. In response, you run away. Trace the events that occur from the initial release of epinephrine to the release of glucose into the blood to the generation of ATP (which ultimately leads to muscle contraction). In your answer explain the processes of a. epinephrine signal transduction leading to glucose release b. cellular respiration using glucose as the substrate and generating ATP c. acetyl choline signal transduction at the neuromuscular junction d. generation of the action potential e. muscle contraction that results
Answer:
a. Epinephrine >> G protein-coupled receptor >> cAMP >> phosphorylation of glycogen phosphorylase and glycogen synthase >> glucose
b. Cellular respiration >> glycolysis >> pyruvate oxidation >> Krebs cycle >> acetyl CoA>> oxidative phosphorylation
c and e. Acetylcholine >> nicotinic receptors >> sodium ions (enter to the cells) >> muscular action potential >> contraction
d. Action potential >> resting potential >> potassium channels open >> sodium channels open >> threshold potential >> voltage-gated sodium channels and potassium channels open >> membrane repolarization >> resting membrane potential (steady state of the cell)
Explanation:
Epinephrine binds to G protein-coupled receptors, triggering the production of cyclic AMP (cAMP). cAMP is a second messenger associated with the phosphorylation of 1-glycogen phosphorylase (GP) that breaks down glycogen (the storage form of glucose) into glucose, and 2-glycogen synthase (GS), involved in the production of glycogen (i.e., phosphorylation inhibits GS activity). On the other hand, during cellular respiration, glucose is used to synthesize ATP via three sequential steps: glycolysis, Krebs cycle and oxidative phosphorylation. During glycolysis, glucose is converted into pyruvate that is subsequently oxidated into Coenzyme A (acetyl CoA), generating NADH and ATP. In the Krebs cycle, acetyl CoA is combined with the oxaloacetic acid to form citric acid, generating NADH, FADH2 and ATP. During oxidative phosphorylation, electrons from NADH and FADH2 are used to pump protons against an electrochemical concentration gradient, which is finally used to synthesize more ATP. On the other hand, during muscle contraction, acetylcholine binds to nicotinic receptors and sodium ions enter the muscle fiber, thereby generating a muscular action potential that travels across muscle cells and triggers muscle contraction when calcium ions (Ca2+) bind to the protein complex troponin by sarcomere shortening (sarcomeres are the functional units of muscle fibers). This contraction ends when Ca2+ ions are pumped back into the sarcoplasmic reticulum (a unique organelle of endoplasmic reticulum in the sarcoplasm). On the other hand, an action potential is defined as a fast and propagating change of the resting membrane potential of neuron cells. In the resting potential, potassium ion (K+) channels open, thereby K+ ions can enter/exit inside the cell. A stimulus causes the depolarization of the cell by opening Na+ channels that enter into the neuron. At the threshold potential, more sodium channels open, thereby voltage across the membrane reaches its most positive value. Subsequently, channels begin to close and more potassium channels open. Finally, the membrane repolarizes (K+ ions leave the cell) and cells return to the resting membrane potential, i.e., the steady-state of the cell.

Answer:
Voluntary motions in the skin, bones, joints, and skeletal muscles are controlled by the somatic nervous system. Both of these PNS systems collaborate with the CNS to control physiological functions and offer responses to external stimuli.
Explanation:
The central nervous system and peripheral nervous system work together as the nerves of PNS comes out from CNS and the peripheral nervous system guide the brain and spinal cord to receive signals from the body to work.
What is the nervous system?The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system. The central nervous system consists of the brain and spinal cord. The peripheral nervous system contains all the nerves which came out from the brain and spinal cord.
Both systems work together as the nerves of the PNS connected with the brain and spinal cord. The nerves signal the brain and brain when giving signals, they travel through the nerves to the body.
Thus, together, the central nervous system and peripheral nervous system control how the brain and spinal cord receive signals from the body to function. The central nervous system sends PNS nerves out from the spinal cord.
