Answer:

A person with sickle cell trait has one mutated copy of the hemoglobin gene, a person with sickle cell disease has two mutated copies.

Explanation:

Sickle cell disease also known as sickle cell anemia is caused by mutation of the beta chain of hemoglobin, the gene for which lies in 11th number chromosome. If a person possess only one mutated gene, then the disease is not expressed in the person. The person then only possess the trait for sickle cell anemia, that is, there is a chance of sickle cell disease in the offspring, but the sickle cell trait are usually asymptomatic or live like normal individual. While the person possessing two mutated gene is said to be suffering from sickle cell anemia and is found to possess S hemoglobin in the red blood cells which is abnormal hemoglobin without any ability to carry oxygen.

with reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.
Katena32 [7]
<span>#1) With reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.

Answer: The way that cell cycle can be lost is by going through changes in the activity of cell cycle regulators. Cancer causes different types of mutations. There are two types of cell cycle regulators that can promote the development of cancer:

-Positive Regulators that can be over activated (become oncogenic).
-Negative Regulators (tumor suppressors) which can be inactivated.

I hope it helps, Regards. <span /><span>

Explain various type of work.
lord [1]

Work: According to physics, work is defined as when a force acting on a body causes it to move a given distance. Work is a scalar number because it is the dot or scalar product of two vectors (force and displacement).

Types of work

1.  Reactionary Work

In the present day, Reactionary Work takes up the majority of our waking hours since we are solely concerned with reacting to messages and demands that come in the form of emails, texts, F4cebook messages, tweets, voicemails, and the list goes on. Instead of taking the initiative in the areas that mean the most to you, you are continuously responding to what is presented to you. You cannot let Reactionary Work overwhelm you, even though it is vital.

2. Planning Work

You must plan how you will accomplish your tasks at other times. Planning work covers the time spent, arranging and prioritizing your time, creating meeting management systems, and perfecting working management systems. Planning involves determining how to spend your energy and creating a strategy for accomplishing your goals. The most engaging processes are highly customized, oftentimes on the verge of becoming neurotic, yet they keep us interested. Planning work may not seem alluring, yet it may increase your productivity and help you achieve your objectives.

3. Procedural Work

Of course, there are a lot of daily actions we take that are neither tactical nor retaliatory. The administrative and maintenance tasks that we perform to stay afloat are referred to as procedural work. Examples include making sure that the bills are paid, filing taxes, updating a presentation deck, and tracking previous outgoing emails to ensure that they were handled or resolved. Although procedural work is crucial, we must always keep an open mind when approaching it. When procedures become outdated and are followed simply out of habit rather than need, they backfire.

4. Insecurity Work

Insecurity Work includes the activities we engage in as a result of our own fears, such as frequently checking internet reviews of you or your goods or compulsively studying certain company statistics. While quickly convincing us that everything is OK, insecurity work doesn't advance the situation at all, and we frequently aren't even aware that we're engaging in it.

5. Problem-Solving Work

The most crucial time for creativity is during problem-solving tasks. Whether we are building a new interface, creating a new business strategy, crafting an insightful blog post, or outlining the features of a new product, this is the task that demands all of our mental capacity and attention. You use pure ingenuity to develop solutions whether you're working alone or with a team.

The most engaging processes are highly customized, oftentimes on the verge of becoming neurotic, yet they keep us interested.
