Why do we say that "an enzyme is reusable"?

2 answers:

5 0

<span>enzymes are resuable as they are biologically catalyst which speeds up the rate of a reaction without being chemically changed themselves. However, if the enzyme is to be denatured under unfavourable conditions (extreme temperatures, extreme pH), the enzymes may not be reusable once denatured.</span>

When an enzyme speeds up it doesnt change so it can be reused

How would you classify corals' role in its community (keystone, dominant, foundation, pioneer, Indicator, or more than one) and

Answer: Keystone species

Explanation: A keystone species is a species which occupied a niche so central in the ecosystem that it has a disproportionately large effect on its environment and other species in it.

The coral's function in its ecosystem is so vital that if you were to remove it, the entire community would be drastically altered beyond recognition.

The coral serves as the base structure of its ecosystem.

That is to say that many corals are hermatypic(they form reefs). This reef serves as the environmental structure of the Coral's ecosystem. Built in and around it is a very biodiverse biotic environment. The coral not only serves as a hiding place and habitat for many marine organisms including fish, clams, lobsters, etc. It serves as resting place for larger animals like turtles and also serves as hunting sites for other animal species.

The most common way of determining a keystone species, is to see what happens when that species is removed from the ecosystem. Coral have shown to be so central to their ecosystem that the bleaching of coral reefs due to tourism and climate change causes a massive loss to biodiversity. And this is quite significant as reefs are the most biodiverse marine habitats.

weird pictures to answer but rubber trees do nothing for an environment so they would be at the bottom then flees which are eaten by aphid insects which are eaten by birds at the top of the chain

malfutka [58]

An infectious disease researcher isolates the pathogen responsible for an emerging disease. The microbe is grown in the lab. Preparation of the laboratory-grown microbe is treated with a lethal dose of ionizing radiation and then tested for its potential as a vaccine and this is Inactivated type of Vaccine.

<h3>What exactly are pathogens?</h3>

Pathogens include viruses, bacteria, fungi, and parasites that can enter the body and harm the immune system. Among many additional viruses that can lead to serious illnesses are anthrax, HIV, the Epstein-Barr virus, and the Zika virus.

<h3>What is vaccination?</h3>

An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular infections.

<h3>Inactivated vaccine:</h3>

In inactivated immunizations, the disease-causing microorganism is eliminated.

Inactivated vaccines typically don't provide as strong of immunity (protection) as live vaccines. Therefore, it can take several doses (booster injections) throughout time to keep up your resistance to diseases.

Using inactivated vaccinations, you can guard against

Flu
Hepatitis A
Polio
Rabies

plz help!!! If this is a sequence of one DNA strand, what is the complementary sequence of the other DNA strand? DNA: A T T C A

gizmo_the_mogwai [7]

Answer:

T A A G T C G C T

Explanation:

DNA strand: A T T C A G C G A

complementary DNA strand: T A A G T C G C T

This is a very important rule:

Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)

And this is how they're coupled:

A = T

C = G

For example::

First DNA strand: A T G C

complementary strand: T A C G
