Thigmotropism is a directional growth movement of curvature which occurs in response to stimulus of contact. Thigmotropism is found in twiners and tendrils. After initial contact with support due to nutation, the tendril or twiner shows less growth in the region of contact and more growth on the other side. As a result they bend over the support.

Answer:

Hello there, I will give the answer

Explanation:

Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.

If the genetically transformed cells have acquired the ability to live in the presence of the antibiotic ampicillin, then what m
V125BC [204]

Answer:

The plasmid must express a gene for ampicillin resistance (the protein product of  the <em>bla</em> gene codes for beta-lactamase, the protein that breaks down ampicillin). The colonies on the ampicillin plate are antibiotic resistant. This means that they have taken up the transformed plasmids expressing both the <em>bla</em> gene and the GFP gene.

Explanation:

The transformation involved the genetic modification of a plasmid to incorporate the gene encoding the green fluorescent protein (GFP) from jelly fish. GFP makes cells glow under UV light.

In genetic engineering, scientists use antibiotic resistance as markers to indicate cells that have been transformed. By incorporating an antibiotic resistance gene such as <em>bla</em> into the vector (plasmid) and then growing the cells in antibiotic media, scientists determine which colonies have taken up the plasmid. Therefore, if the cells survive, this means that they contain the plasmid with antibiotic resistance gene as well as the GFP gene.

Provides great strength through parallel bundles of collagenic fibers found in tendons
tiny-mole [99]

Answer:

<h2>Dense connective tissue.</h2>

Explanation:

This is a type of connective tissue that has fibers, which are composed of collagen. You can refer to the image attached to see the parallel bundles of these collagenic fibers.

So, basically this formations help to forms strong tissue like tendons or ligaments.

Which ecosystem service would suffer from the opening of a mineral mine along a small mountain range?
andreyandreev [35.5K]

Answer:

D. Supporting

Explanation:

Ecosystem services include provisioning, regulating, culture and supporting services.

Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.

Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.

Hence, the correct answer is "D. supporting".
