What releases enzymes to digest molecules outside of a cell

To test a new drug that has the potential of curing people of the common
cold a company asked human volunteers who were coughing and sneezing
to participate in a clinical study. The objective of the experiment was to test
whether the new drug could cure the volunteers in the experimental group of
the common cold. But instead of two groups, these volunteers were randomly
divided into three groups and treated as follows:
Group
Experimental
Group
Yes
Control
Group 1
NO
Control
Group 2
No
New ONS
Orange
Bedre
Yes

Which of the following is the best explanation of why a second control group
was included in this experiment?
O A To prove that the common cold cannot be cured
B. To provide the volunteers in the study with something to drink
O C. To help researchers conclude that results are related to the new
drug and not to the orange juice
O D. To confuse anyone who is trying to steal their new drug and sell it

From when we are very little, we are taught to know the difference between right and wrong and how to follow rules. As we get older, rather than the rules that we followed as children, we learn to follow laws that allow us to function as adults in today’s society.

We are all probably familiar with traffic laws or laws about stealing or committing crimes, but did you know that there are laws and public policies written specifically for and about families?

If you didn’t already know about these particular laws, now is your chance to find out!

For this activity, you will be researching the various laws and public policies related to families. In addition, you will be creating several scenarios where these laws might come into play.

Activity Guidelines:
You will start by researching various laws and public policies that pertain to families. You can really take this research in any direction that you like, while keeping in mind that the ultimate goal will be to write five short scenarios and connecting each one to a different family law or policy. For example, you could write a scenario that involves a parent who is intentionally hurting their child and connect this scenario to a child abuse law.

Each scenario description should be no more than about one paragraph in length. You are welcome to include dialogue in your scenario or simply summarize and explain your scenario idea. After each scenario, you will write the specific family law or policy being broken in the scenario or how it otherwise pertains to the scenario. The name of the law or policy and a brief explanation of its connection to the scenario is all that you need to include.
WILL MARK BRAINLY-IST
A basic template is included below. Feel free to use it or create your own in a word processing or slideshow program.

Your grade will be based on creating all five scenarios and your ability to connect each one to a different family law or policy. For further details on how you will be graded, see the rubric below.

The viral DNA incorporates itself with the host cells and replicates whenever the host cell replicates itself.

A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.

A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.


A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
