Due to Natural Selection, it is likely that the allelic frequency would change to favor iguanas with webbed feet. Those animals with webbed feet would have an easier time navigating their environment, which gives them an advantage over those that do not. Hope this helped!
Biotic natural resources also include fossil fuels such as coal and petroleum which are formed from organic matter that has decayed. Abiotic: these resources come from non-living and non-organic material. Examples of these resources include land, fresh water, air, and heavy metals (gold, iron, copper, silver, etc.).
C
Crossing over during meiosis allows for genes to cross from one chromosome to another. This will result in more mutations and therefore greater genetic diversity.
Answer:
b. Basement membrane
Explanation:
Together, the endothelial cells of the glomerular capillaries and the podocytes that completely surround the capillaries form a permeable barrier called filtration membrane or endothelial capsular membrane. This sandwich arrangement allows filtration of water and small solutes, but prevents filtration. of most plasma proteins, blood cells and platelets. The filtered substances move from the bloodstream through three barriers: a gIomerular endothelial cell, the basal lamina and a filtration slot formed by a podocyte.
1 The endothelial cells of the gIoméruIo are quite permeable because they have large perforations (pores) of 70 to 100 nm (0.07 to 0.1 ml) in diameter. These dimensions allow all solutes of the blood plasma to leave the gIomerular capillaries, but prevents blood cells and platelets from leaking. The mesangial cells, contractile cells that help regulate gIomerular filtration are located in the middle of the gomeromer capillaries and the groove formed between the afferent and efferent arterioles.
2 The <u>basement membrane</u> is a layer of acellular material between the endothelium and podocytes, which consists of fibruses in a gIucoprotein matrix; prevents filtration of large plasma proteins.
3 From each podocito thousands of extensions in the form of feet called pedicels that surround the glomerular capillaries extend. The spaces between the pedicels are called filtration cracks. A thin membrane, the crack membrane, extends through each filtration crack and allows the passage of molecules with a diameter smaller than 6 to 7 nm (0.006 to 0.OO7 mm), including water, glucose, vitamins, amino acids , very small plasma proteins, ammonia, urea and ions. Since the most abundant plasma protein, <u>albumin</u>, has a diameter of 7.1 mm, less than 1% of it crosses the membrane of the crack.
Answer: 1. particles vibrate
more
2. individual particles do not
get ( change their temperature).
3. They vibrate less and become
motionless
Explanation:
when the tray is placed in the oven,the particles get heated ( this results in a change in temperature.) as the temperature increases so does their kinetic energy. What this simply implies is that the particles would tend to vibrate more vigorously than before.
When you remove the tray from the oven it’s temperature decreases, so also is it’s kinetic energy. This makes the particles to vibrate slowly and become motionless.
