What type of molecule should be able to pass through the cell membrane most easily?

Answers

Answer 1

Small and hydrophobic molecules should be able to pass through the cell membrane most easily.

The cell membrane is a selectively permeable membrane that separates the interior of a cell from the exterior of a cell.

The cell membrane is mainly made up of a phospholipid bilayer. The phospholipids are arranged in such a manner that the heads made of phosphate are pointing outwards and the tails made of lipids are pointing inwards.

The heads are hydrophilic whereas the tails are hydrophobic. Hence, molecules that are hydrophobic and small can easily pass through the cell membrane as they do not get trapped by the tails. On the other hand, hydrophilic molecules as well as large molecules will have difficulty passing through the cell membrane.

The compensation depth is the depth at which daily or seasonal ________ is sufficient to allow photosynthesis to occur.

Answers

The compensation depth is the depth at which any seasonal light is sufficient to allow photosynthesis to occur.

What is compensation depth?

The depth at which the pace of carbonate accretion matches the speed of carbonate dissolution is known as the calcite compensatory depth (CCD) in oceanography. Rivers and hydrothermal vents in the deep ocean are the sources of carbonate entering the ocean.

The world's oceanic ridges are cut by the CCD, and as a result, they are mainly covered in carbonate oozes, a kind of biogenic ooze comprised of skeleton fragments. About half of the world's ocean floor is covered by carbonate oozes, which are mostly found at a depth of 4,500 metres (about 14,800 feet); below that depth, they dissolve swiftly.

Compared to the Pacific basin, the Atlantic basin's CCD is 500 metres (approximately 1,600 feet) deeper, which reflects both a higher rate of input and a slower rate of dissolution. The CCD has varied by nearly 2,000 metres because of changes in input, productivity, and dissolution rates throughout geologic history (about 6,600 feet).

Therefore, the depth at which any seasonal light is sufficient to allow photosynthesis to occur is called compensation depth.

How do cortical and juxtamedullary nephrons differ with respect to reabsorbing nutrients and concentrating urine?

Cortical and juxtamedullary nephrons differ with respect to reabsorbing because

Cortical Nephron is a tiny structural and functional unit of the kidney that only enters the outer renal medulla by a brief Henle loop. These nephrons' Malpighian corpuscles are found in the outer region of the renal cortex.

Every vertebrate has cortical nephrons. Cortical nephrons make up about 85% of all nephrons in the human kidney. They carry out a large portion of the body's regulatory and excretory processes.

The glomerulus, a tiny capillary network, is situated at the start of each cortical nephron in the outer renal cortex. The glomerulus' primary job is to filter blood that enters from an afferent arteriole in the renal arterial circulation. the filtration process, water, ions, and amino acids.

The kidney's juxtamedullary nephron is a tiny anatomical and functional unit with a protracted Henle loop that extends deep into the renal medulla. These nephrons' renal corpuscles are located near to the renal medulla.

Juxtamedullary nephrons are only found in mammals and birds. Juxtamedullary nephrons make up about 15% of all nephrons in the human kidney. A sizable glomerulus may be found at the start of each of them. In comparison to cortical nephrons, the juxtamedullary nephrons filter more fluid due to their larger glomeruli.

If the ventral cells of an early frog gastrula are experimentally induced to express large amounts of a protein that inhibits BMP-4, could a second embryo develop? Explain.

Bone morphogenetic protein 4 is known as BMP-4 (BMP - 4).

On the dorsal side of an embryo, BMP-4 appears to be inactivated by the cells of the organizer by generating proteins that bind to it and prevent it from sending a signal. As a result, dorsal structures like the neural tube and notochord can arise.

Because decreasing BMP-4 activity would have the same effect as transplanting an organizer, a second embryo might emerge if the ventral cells of an experimentally-induced premature frog gastrula express proteins that block BMP-4.

Which process in the nephron is least selective? a. filtration b. reabsorption c. active transport d. secretion

Answers

Filtration process in the nephron is the least selective and hence option (a) is the correct answer.

(i) Filtration- First, body fluid is collected. The initial fluid collection usually involves filtration through selectively permeable membranes consisting of a single layer of transport epithelium. These membranes retain cells as well as proteins and other large molecules in the body fluid; hydrostatic pressure forces water and small solutes, such as salts, sugars, amino acids and nitrogenous wastes, into the excretory system. This fluid is called filtrate. Even when filtration occurs, fluid collection is non-selective and essential molecules are recovered from the filtrate and returned to the body fluids.

(ii) Reabsorption- This step is a selective process and excretory system use active transport to reabsorb valuable solutes such as glucose, certain salts and amino acids from the filtrate.

(iii) Secretion - Non essential solutes, wastes i.e., excess salts, ions, toxins are extracted from the body fluids and are added to the contents of the excretory tubule. This step also uses energy.

(iv) Excretion - The processed filtrate is then excreted from the system and from the body as urine.
