Which genus of single-celled organisms feeds by surrounding its food
with cytoplasm and engulfing it?
Answers
Answer:Amobea
Explanation:
The single-celled organism that feeds its food from the surrounding by engulfing is Amoeba. Amoeba is unicellular organism, generally found in freshwater pools, lakes, and in aquatic vegetation.
Amoeba is a unicellular organism belonging to the group of protozoa. It reproduces through binary fission. The amoeba has the ability to change its shape, which helps the organism to obtain food from the surrounding. Amoeba protrudes the cytoplasm by making a finger-like projections, known as pseudopodia. The pseudopodia engulfs the surrounding food particle by making a food vacuole. This process of engulfing food is known as phagocytosis.
Therefore, the amoeba uses phagocytosis to engulf food particle.

Explanation:
one feature of the fluid mosaic model of membrane structure is called the . a. pleated sheet b. lipid bilayer c. microfilament d. hydrophilic sheet
Answers
The answer to your question is b. lipid bilayer.
The fluid mosaic model of membrane structure suggests that the cell membrane is made up of a phospholipid bilayer, which is a two-layered structure of phospholipid molecules arranged tail-to-tail. The polar heads of the phospholipids face outward, interacting with the aqueous environments of both the extracellular and intracellular spaces, while the nonpolar tails face inward, interacting with each other in the hydrophobic interior of the membrane. This arrangement creates a flexible, fluid-like structure that allows for membrane proteins and other molecules to move freely within the membrane.
Therefore, the lipid bilayer is a key feature of the fluid mosaic model of membrane structure.

What are the five conditions that must be met for the Hardy Weinberg equation to be used and what do they mean
Answers
The five conditions that must be met for the Hardy-Weinberg equation to be used are as follows: Large Population size, Random Mating, No migration, No natural selection and No mutation
Large Population Size: The population must be large enough to make it likely that chance alone will not result in the significant deviation of the genotype frequency from the expected.
Random Mating: All members of the population should have an equal chance of mating with each other. If not, there will be an unequal distribution of alleles in the population.
No migration: Migration of new alleles into the population can disrupt the genetic equilibrium of the population.
No natural selection: There should be no natural selection against any of the genotypes. Selection can occur when certain genotypes have a survival or reproductive advantage over others.
No mutation: Mutations can change the frequency of alleles in the population, which can lead to the Hardy-Weinberg equilibrium being disrupted.

if t takes P-wave five minutes to travel from the epicenter of an earthquake to seismic station, approximately how long will it take for a S-wave to travel the same distance?
Answers
An S-wave would therefore need to travel the same distance from the epicenter to the seismic station in about 8.33 minutes.
S-waves move at a speed that is typically between 60% and 70% that of P-waves. For this computation, a cautious estimate of 60% is used.
We can calculate the time it would take for an S-wave to traverse the same distance if P-waves take five minutes to reach the seismic station by dividing the P-wave time by 0.6:
Time for S-wave equals Time for P-wave / 0.6, or 5 minutes divided by 0.6 results in 8.33 minutes.

Edema, as mentioned, is the swelling that is caused due to excess fluid in our body’s tissues. It may effect any part of our body, but most commonly is noticed in hands, feet, ankle, etc. Your skin can be stretched due to edema, and the swelling can increase, if not treated on time and cause serious health issues.

Explain the processes involved in the transportation of absorbed
nutrients throughout the body.
Answers
Answer:
Absorption: The process of absorbing nutrients occurs primarily in the small intestine. Once the food is broken down into smaller molecules through digestion, these molecules are absorbed into the bloodstream. For example, carbohydrates are broken down into simple sugars, proteins into amino acids, and fats into fatty acids and glycerol.
Circulatory System: The circulatory system, composed of the heart, blood vessels, and blood, plays a crucial role in transporting absorbed nutrients. The blood vessels form an extensive network that reaches all tissues and organs in the body.
Hepatic Portal System: After absorption, most of the nutrients are transported to the liver through a specialized system called the hepatic portal system. This system ensures that the liver, which performs various metabolic functions, receives a concentrated supply of nutrients before they are distributed throughout the body.
Bloodstream Transport: Once in the bloodstream, nutrients are carried by the plasma, the liquid component of blood. Different nutrients use specific mechanisms for transport:
Glucose: It is transported by facilitated diffusion or active transport, depending on the concentration gradient, with the help of insulin.
Amino Acids: They are transported through the bloodstream by specific carrier proteins.
Fats: Dietary fats are initially packaged into structures called chylomicrons and transported through the lymphatic system before entering the bloodstream. Once in the bloodstream, fats are carried by lipoproteins such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
Distribution to Tissues: As the blood circulates, nutrients are distributed to various tissues and organs according to their specific needs. Nutrients are delivered to cells through the capillaries, the smallest blood vessels in the body, which have thin walls that allow for the efficient exchange of nutrients and waste products.
Cellular Uptake: Nutrients are taken up by cells through various mechanisms. For instance, glucose enters cells with the help of insulin, while amino acids are transported into cells through specific carrier proteins. Fats are taken up by cells through receptor-mediated endocytosis or by diffusion.
Metabolism: Once inside the cells, nutrients undergo metabolic processes to produce energy or build new molecules. Glucose, for example, can be metabolized through glycolysis, the Krebs cycle, and oxidative phosphorylation to generate ATP, the cell's energy currency.
Waste Removal: Metabolic byproducts, such as carbon dioxide and urea, are generated during nutrient metabolism. These waste products are transported back into the bloodstream and eventually eliminated from the body through the lungs (carbon dioxide) or the kidneys (urea).
It's important to note that different nutrients may have different transport mechanisms and pathways. The body's ability to efficiently transport and utilize absorbed nutrients is vital for maintaining proper functioning and overall health.
