What are the components of the extracellular matrix of bone? Blood? Describe how these different matrices contribute to the different functions of bone and blood?
Answer:
The Bone Extracellular Matrix in Bone Formation and Regeneration
Explanation:
Bone regeneration repairs bone tissue lost due to trauma, fractures, and tumors, or absent due to congenital disorders. The extracellular matrix (ECM) is an intricate dynamic bio-environment with precisely regulated mechanical and biochemical properties. In bone, ECMs are involved in regulating cell adhesion, proliferation, and responses to growth factors, differentiation, and ultimately, the functional characteristics of the mature bone. Bone ECM can induce the production of new bone by osteoblast-lineage cells, such as MSCs, osteoblasts, and osteocytes and the absorption of bone by osteoclasts. With the rapid development of bone regenerative medicine, the osteoinductive, osteoconductive, and osteogenic potential of ECM-based scaffolds has attracted increasing attention.

A 5'6", 210 pound, 64 year old man had a physical exam prior to his retirement for corporate work. His blood pressure was greater than 180/115 mmHg on three separate days (normal blood pressure is 120/80). Further examination showed normal to low plasma renin activity, elevated systemic vascular resistance (SVR), x-ray showed left ventricular hypertrophy and retinal hemorrhage and cardiac output was 7.2 L/min (normal is 3.5 to 5.5 L/min). Recommended therapy was weight reduction to his ideal weight, low salt diet. If these life style changes did not change his condition the following medication will be started in the following order: oral diuretics progress to beta blockers and then to a vasodilator.
Required:
a. What is the diagnosis for this individual?
b. Why is it suggested that the patient go on a low sodium diet?
c. Explain the site and mechanism of action of each of these prescribed medications.
Answer:
Explanation:
a.
The individual should be diagnosed for hypertension or high blood pressure.
b.
It is recommended that the patient should take low sodium diet because when sodium or salt enters the blood stream it increases the amount of water or fluids in the blood stream that leads to rise in blood pressure. The blood pressure increases if we take high salt diet due to which arterioles constrict.
c.
Diuretics- Diuretics are the first recommended therapy in treating hypertension. Diuretics such as thizides , pottasium sparing agents. Thiazide acts on distal convoluted tubule that inhibits Na+ and Cl - symporter. Diutetic removes water from body as urine and loss of salt.
Beta blockers - These are antagonists. They block the beta receptors found on the target cell membrane. Beta blockers slows down blood pressure. Atenolol is the beta blocker used for hypertension.
Alpha1 blocker - alpha 1 receptors helps in smooth muscle contraction and vasoconstriction. Vasodilator increases blood flow in the body that are devoid of oxygen that helps to reduce blood pressure.
angiotensin converting enzyme inhibitor - blocks angiotensin converting enzyme that prevents converting angiotensin I to angiotensin II and increases bradykinin levels in the body. These inhibitors helps in lowering blood pressure.

Consider the factors that affect muscular strength. Read each scenario and then identify each label into the appropriate category based on whether each would result in a stronger or weaker muscle contraction.
a. Potassium accumulate in the sarcoplasm
b. Increase in muscle belly circumference
c. Lesser proportion of motor neurons to muscle fibres
d. Begin contractions with muscle already 50% contraction
e. Lower sarcoplasm pH
f. Increased stimulus frequency.
g. Circular arrangement of muscle fascicles
h. increased requirement.
Answer:
1. Weaker contraction:
a. Potassium accumulate in the sarcoplasm
d. Begin contractions with muscle already 50% contraction
e. Lower sarcoplasm pH
g. Circular arrangement of muscle fascicles
2. Stronger Contraction
b. Increase in muscle belly circumference
c. Lesser proportion of motor neurons to muscle fibres
f. Increased stimulus frequency.
h. increased requirement.
Explanation:
Sarcoplasm refers to the cytoplasm of muscle cells which contains ATP, enzymes, and a variety of ions, including potassium (K+). The negative potential required during muscle activity is produced from the disequilibrium of ionic concentrations (mostly Na+ and K+) across the membrane, which is generated through Na+/K+ ATPase pumps. During contraction, a muscle shortens, and thus its circumference increases. The generation of lactic acid is known to lower pH in the sarcoplasm and thus hinder the force and power development of the muscle fibers. Muscle fascicles can be arranged in concentric rings, it is a common pattern in sphincter muscles that modulate the opening and closing of orifices (which have weak contractions). A motor unit refers to a single efferent neuron and all of the muscle fibers it modulates. Each individual muscle fiber is innervated by one motor neuron, whereas a single motor neuron can innervate many muscle fibers. Finally, higher intensity/frequency are known to induce stronger muscular contractions, but also produce a stronger decline in force and cause more rapid muscle fatigue.
A relationship in which one species kills and consumes another species is known as
predation.
parasitism.
commensalism.
mutualism.
A relationship in which one species kills and consumes another species which is called as the Predation. So, the correct option is A.
What is Predation?Predation is defined as the relationship in which one species kills and consumes another species. It is a type of community relationship in which organisms of one species, also known as predator, consume the tissues of organisms of another species, called prey, which means killing the prey and killing all or most of the prey organisms.
Herbivores are explained as predators in which the prey organism is a plant. Predation is described as the natural way of transferring the energy fixed by plants to higher trophic such as snake eating a frog tiger killing and eating a deer.
Therefore, the correct option is A.

A trait has two alleles, represented by p and q. If p = 0.89, what is q?
Answer: 0.11
Explanation:
According to the Hardy-Weinberg principle, it's stated that the sum of the two alleles must be 1.
In this case, we've been given that a trait has two alleles, represented by p and q and p is given as 0.89, then the value of P will be:
p + q = 1
q = 1 - p
q = 1 - 0.89
q = 0.11
Therefore, q is 0.11

The hay included as part of the culture medium provided a food source for bacteria. Bacteria are a good food source for some types of protists.
a. Explain which group(s) of protists would not have survived because they have no way to produce their own food.
b. Explain which group(s) of protists would have survived without this food source.
Answer:
Protozoans → would not have survived because they have no way to produce their own food → HeterotrophsAlgae → would have survived without this food source → HeterotrophsExplanation:
The protist kingdom is composed of two main groups. The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.
Algaes are autotroph Protozoans are heterotrophProtozoans:
Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on bacteria, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.
Algae:
Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.
