Answer:
A
Explanation:
Correct answer is
A.) No. Theories can be refined and improved over time, but cannot become scientific laws.
Answer:
In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth.
Answer:
Option D, telophase
Explanation:
Telophase is the last stage of mitosis cell division in which the duplicated genetic material gets arranged into two identical daughter cells. In generals, this phase begins once the replicated, paired chromosomes have separated and arranged themselves on two opposite sides, or poles of the cells. After this, nuclear envelope begins to form around the chromosomes. After telophase, the cell undergoes cytokinesis to divide the cytoplasm of the parental cell into two daughter cells.
Hence, option D is correct
<u>Answer</u>:- Active transport
<u>Explanation</u>:-
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 <em>high concetration to low concentration.</em>
2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from <em>low concentration to high concentration.</em>
<em>The active transport is of two types:</em>
1. <em>Primary active transport-</em> in this type of transport <em>ATP</em> is used as an energy source to move the substances against the concentration gradient.
2.<em>Secondary active transport</em> - 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 <em>carrier proteins</em>. 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 <em>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.</em>
Your answer is going to be Hydrolysis
