Answer:

True  

Explanation:

Convergent evolution is a type of independent evolutionary process by which unrelated species evolve similar structural features/traits that fulfill the same or similar functions. Convergent evolution generates analogous structures, i.e., structures that have similar functions in organisms that don't share a common ancestor with such phenotypic traits. An example of convergent evolution is the wings of insects (e.g., butterflies), birds and bats. Conversely, divergent evolution is a type of evolutionary process that creates homologous structures/traits in closely related organisms because such features were inherited from a common ancestor.

Answer:

Lipids. Peroxisomes are involved in the metabolism of amino acids and lipids due to their oxidation reactions that break down lipids and fatty acids.

Explanation:

Hope this helped!

Peroxisomes perform important functions that include lipid metabolism and chemical detoxification. It undergoes oxidation reactions which break down fatty acids and amino acids.

Peroxisomes are types of organelles which sequence diverse oxidative reactions and play important roles in metabolism, reactive oxygen species detoxification and signaling. Oxidative pathways located in the peroxisome include fatty acid β-oxidation, which contributes to embryogenesis, seedling growth and stomatal opening.

It contains a variety of enzymes which work together to rid the cell of toxins primarily, and in particular hydrogen peroxide which is a normal byproduct of cellular metabolism.

Peroxisome is a membrane bound organelle that occurs in the cytoplasm of eukaryotic cells. Peroxisomes play an important role in the oxidation of specific biomolecules and contribute to the biosynthesis of membrane lipids called plasmologens.

Thus, Peroxisomes perform important functions that include lipid metabolism and chemical detoxification. It undergoes oxidation reactions which break down fatty acids and amino acids.

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

Answer: The particles that can pass through the cell membrane are the GREEN SOLVENT PARTICLES.

Explanation:

OSMOSIS can be defined as the thermal movement of solvent (water molecules) through a selectively permeable or semi-permeable membrane from a region of high concentration of the solvent to one where they are in low concentration.

The cell is bound by a membrane called plasma membrane. This membrane is selectively permeable and allows water and certain dissolved solvents to pass through it. As a result, the plasma membrane of the cell regulates the movement of materials between the cell and it's environment.

From the osmosis gizmo, it portrays a typical example of osmotic reaction occuring between a cell immersed in a solution of purple solute particles dissolved in green solvent particles. In order to maintain an osmotic balance between the cell and the solution surrounding it, the solvent (which is the green solvent particles) will move from the region of higher concentration to a lower region through the cell membrane

Answer:

The orchids derive nutrients from the association at very young stages of its life cycle while the fungi obtain water and organic matter

Explanation:

As stated in this question, fungi species belonging to the phylum Basidiomycota form mycorrhizal associations with a flowering plant called orchids. This relationship is a mutualistic one because both participants benefit from the relationship.

In this association, the young orchid plant relies on the mycorrhizal fungi's metabolism to get nutrients needed for its development in form of carbohydrates while the fungi in return gets water (from the roots of the plant) and organic matter.

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.

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.

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.

Answer:

Explanation:

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.

Protozoans:

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.
