what is spirogyra in biology​

Answers

Answer 1

Answer:

Spirogyra is a genus of green algae that belong to the order Zygnematales. These free-flowing, filamentous algae are characterized by ribbon-shaped chloroplasts that are arranged in a helical manner inside the cells. So the name is derived from the spiral arrangement of chloroplasts in these algae.

Some species of reptiles can regenerate body parts if the parts are lost due to injury. How can the reptiles regrow these body parts?

Answers

Answer:

the axolotl ( say "ax- oh- lot-el") is a Mexican species of salamendar . its also known as mexican walking fish .it can regenerate , repair or replace its arms,legs,tail ,lower jaw ,brain and heart

Explanation:

in reptile involves dropping a section of their tail and regenerating it as part of a defense mechanism

The reptiles regrow the body parts which are lost due to injury by the action of regeneration.

What is Regeneration?

Regeneration may be defined as a process through which the reactivation of development into post-embryonic life in order to restore missing or damaged tissues is carried out.

The process of regeneration is carried out in Hydra (Morphollactic regeneration), Planaria (Stem cell-mediated regeneration), Salamander (epimorphic regeneration), and Mammalian liver (compensatory regeneration).

In reptiles like Salamander, epimorphic regeneration is carried out through which differentiated cell undergoes cell dedifferentiation in order to form regeneration blastema. This region is stimulated by the apical ectodermal cap (AEC).

Therefore, the reptiles regrow the body parts which are lost due to injury by the action of regeneration.

A good cancer medicine will stop cells from dividing out of control. What might be the side effects of this medicine? Explain your answer.

Answers

Cancer cell proliferation relies on the ability of cancer cells to grow, transition through the cell cycle, and divide. To identify novel chemical probes for dissecting the mechanisms governing cell cycle progression and cell division, and for developing new anti-cancer therapeutics, we developed and performed a novel cancer cell-based high-throughput chemical screen for cell cycle modulators. This approach identified novel G1, S, G2, and M-phase specific inhibitors with drug-like properties and diverse chemotypes likely targeting a broad array of processes. We further characterized the M-phase inhibitors and highlight the most potent M-phase inhibitor MI-181, which targets tubulin, inhibits tubulin polymerization, activates the spindle assembly checkpoint, arrests cells in mitosis, and triggers a fast apoptotic cell death. Importantly, MI-181 has broad anti-cancer activity, especially against BRAFV600E melanomas.

Active transport of fluid and electrolytes across the cellular membrane typically requires?

Answers

Active transport requires energy in the form of ATP conversion, carrier proteins, or pumps in order to move ions against the concentration gradient.

Active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.

Active or passive transport?

Passive transport is a great strategy for moving molecules into or out of the cell. It's cheap, easy, and all the cells have to do is stop and let the molecules diffuse.

In active transport, as opposed to passive transport, the cell expends energy (eg, in the form of ATP) to move a substance against its concentration gradient.

With this information, we can conclude that the active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.

Answers

Answer:

Igneous rocks are classified on the basis of their composition and their texture. Magma, and the igneous rock it becomes, has a range of chemical compositions. For example, basalt is a mafic lava flow rock which originates from melting of the upper mantle.

Explanation:

Answer:

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

Fill the container to the top with the particles. Place your hand tightly over the top of the container and shake it. What state of matter does this represent? Explain.

Answers

Answer:

It should be solid.

Explanation:

Solids have little to no movement in their particles. If you were to fill it to the top and shake, not much would move, therefore representing solids.

Particles are the unit that makes the matter. The states of matter based on particles can be solid, gas, or liquid. The matter in the experiment represents solid matter.

What are phases of matter?

The phases or states of matter are based on the composition and the distribution of the particles of the object. There are four known and observable states of matter namely solid, gas, plasma, and liquid.

The gas is the freest and most spaced particle with no fixed volume and shape. On the other hand, the particles of a liquid are a little closer than the gas but do have an indefinite shape.

The solid has particles closely packed with no space, which makes them have a definite shape and volume. When a container filled with particles is shaken, there is no movement as they are very closely packed, like solid.

Therefore, the container represents solid matter.
