The gecko's feet contain molecules that are attracted to the molecules on the surface.

Geckos are lizards which belongs to reptile group. They are found in warm climatic regions of the world. Geckos and some other animals can climb smooth surfaces because of presence of Van der waal forces of attraction between the molecules of gecko's feet with molecules of the surface. The force of attraction is generated due to fluctuations or differences in charge present in molecules of feet and that of surface. The charge fluctuations generally comes into sync and generate attractive force.

<h3>What are the features of Geckos ?</h3>

Most geckos are small, soft-skinned reptiles that are often nocturnal in behaviour. A small, robust body, a big head, and often well-developed limbs are other features they have. Each limb's tips are frequently fitted with digits that have adhesive pads.

  • The gecko possesses a variety of adaptive traits that help it avoid or confound predators. If a predator catches the gecko by the tail, the tail can be cut. One of the most well-known characteristics of the species is this. Some geckos may also alter their colour to better fit their surroundings.

ArbitrLikvidat [17]

Answer:

E. They decrease the rate at which Ras hydrolyzes GTP.

Explanation:

Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.

Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.

Dandelions can produce seeds by both asexual and sexual
LUCKY_DIMON [66]

Answer:

only appear in veg plants

Explanation:

Unlike other forms of asexual reproduction in plants such as vegetative plant propagation via cuttings, apomixis is asexual reproduction via seeds. In the case of most dandelions (i.e., Taraxacum officinale), the embryo in the seed forms without meiosis, thus the offsping are genetically identical to the parent.

Humans deplete the most resources when
Studentka2010 [4]

Answer:

Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.

Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

BlackZzzverrR [31]
<h2>Calculate the Rf values</h2>

Explanation:

  • In the event that an alternate dissolvable were utilized, the Rf worth would not be the equivalent on the grounds that, contingent upon the dissolvable, there is a distinction in dissolvability. On the off chance that an alternate dissolvable was utilized, the general places of the groups would be different.
  • The Rf estimation of the xanthophyll is 66% that of carotene since xanthophyll has a H bond with cellulose, which backs it off, and makes it less dissolvable in the dissolvable.
  • Carotene is progressively dissolvable in 9:1 oil ether CH3)2CO arrangement, which made it be conveyed higher and have a bigger Rf value.
  • Measure the separation the dissolvable voyaged, which is Df, and measure the separation the test arrangement voyaged, which is Ds.
  • Ascertain the maintenance factor utilizing this condition <em>RF = Ds/Df. </em>
  • Basically isolate the separation the arrangement went by the separation the solvent traveled.
