Answer: 1. Disaccharide
2. two monosaccharides, galactose and glucose
3. the role of lactase is to catalyse the hydrolysis of the disaccharide lactose to yield the monosaccharides galactose and glucose
Explanation:
Lactose is a disaccharide, consisting of two monosaccharide units joined by a beta 1–>4 glycoside link
Lactase cleaves the glycoside link, giving two monosaccharides, galactose and glucose
Answer:
The answer to your question is d) Metaphase ll
Explanation:
Metaphase ll is the second stage of Meiosis ll after Profase ll. During this phase, chromosomes align along a single plane in the center of the cell. As we can see in your picture.
During this phase, the chromosomes are preparing themselves to be divided in the next phase (Anaphase ll).
The area affected by the ship that were involved in an accident is = 333 million liters
An oil spill can affect bird nesting near a contaminated body of water through its food chain.
<h3>What is oil spillage?</h3>
Oil spillage is defined as the release of used or oil wastes into a water body through a tanker, offshore drilling rig, or underwater pipeline.
The area affected by the ship that were involved in an accident can be calculated by the addition of the various areas affected by the tanker, ship and super tanker.
That is, 32,000 + 1,200,000 + 332,000,000
= 333,232,000
Which is approximately 333 million liters.
A bird that is nesting near the contaminated body of water can be affected through its food chain.
This is because birds which depends on fish can eat fish for this contaminated water which must have accumulated some level of harmful organic substances on its body surfaces.
Therefore when eaten by the bird their health would be affected negatively.
