Answer:

Or i think its capillary action

Explanation:

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.

Artyom0805 [142]

Answer:

The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons of matter are converted into neutrinos, solar radiation, and roughly 4 x 1027 Watts of energy

How do individual cells maintain homeostasis?

erica [24]

Individual cells, as well as organisms, must maintain homeostasis in order to live too. One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area

sashaice [31]

Answer:- Active transport

Explanation:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from high concetration to low concentration.

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from low concentration to high concentration.

The active transport is of two types:

1. Primary active transport- in this type of transport ATP is used as an energy source to move the substances against the concentration gradient.

2.Secondary active transport - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.

The membrane proteins that are associated with active transport are called as carrier proteins. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.
