Answer:

b, this is because a consumer, is something that consumes something, and the clam consumes the energy and nutrients when it filters the particles in from the water. Because it consumes these, it is a consumer for that reason. So, the answer is b. Hope this helps!!!

Describe how mutations lead to genetic variations.
pickupchik [31]

Describe how mutations lead to genetic variations.

Mutations are changes in the DNA sequence of any organism. These DNA sequence comprise genes which control all the traits of an organism such as height, weight, eye color or which specific protein will be formed in body at which time. Everything is controlled by tiny pieces of DNA. If there occurs any change in the DNA sequence of an organism, it can be lethal to it, for example: In case of cancerous mutations where proteins controlling cell division are badly affected. Other mutations are simply passed to the offspring leading to genetic variations in the offspring. This is how mutations leads to the changes in genetic of an organism.

Which appears to be more dangerous: the BRC1 or BRC2 mutation?

The BRC1 and BRC2 are mutations or changes in the BRCA gene of humans mostly females. BRCA gene is basically a tumor suppressor gene which in some cases undergo mutations of different types. Some of which can be unharmful while BRC1 and BRC2 are typically very dangerous mutations because they increase the chances of a woman to develop breast cancer. Woman with BRC1 and BRC2 mutations have five times more risk of developing the breast cancer than other women. Studies suggest that BRC1 mutation is more dangerous than BRC2 mutations because a greater number of patients seen have BRC1 kind of mutation. Moreover, BRCA1 is associated with triple-negative breast cancer response in which a person cannot be fully treated with some drugs like which does not respond to hormonal trastuzumab and hormonal treatments.  

Analyze a woman’s risk of dying of cancer if she carries a mutated BRC1 gene.

The risk of a woman to die with cancer due to with BRC1 mutation are quite high. This is because 18 percent of the women which develop breast cancer due to BRC1 mutation die while only 2.8 percent of the women who develop breast cancer due to BRC2 mutations die. This indicates substantially higher risk of BRC1 patients of dying as compared to BRC2 patients.

How do heredity and inheritance relate to the data presented in these charts?

Please add charts.

What data would you need to see in order to draw conclusions about the effectiveness of preventive surgeries?

There are several preventive surgeries used to prevent the chances of breast cancer in women. However, the genetic history of a person and her family’s genetic history is important to see before drawing some effective preventive surgery.

What does the age at diagnosis tell you about the mutation?

By looking at different cases of breast cancers and analyzing the data of different countries, we noticed that,  the onset of disease takes several years because it is a genetic level mutation and the onset of mutation starts in earlier years of a woman’s life however she fully becomes a victim and notices it in late years of her life. This is why it cannot be easily diagnosed in early years even it is present there.

Explain how breast-cancer genes are still present in the population, despite cancer-related surgeries and deaths.

The genes responsible for breast cancer such as BRC1 and BRC2 are inherited from parents to offspring in a dominant fashion which means only one copy of gene is enough for the onset of the disease. Also because the disease is caused due to genetic level mutations, even if the doctors remove the cancers through surgeries they are not able to remove each and every affected gene from an organism which is passed from parents to offspring and still present in population.

Hope it helps!

Which symptom should the nurse monitor for when caring for a client whose sinus bradycardia has been treated with large doses of
Rufina [12.5K]

When a patient is treated with large doses of atropine, the nurse should look out for symptoms relating to the drug's antimuscarinic properties like blurred vision, constipation, difficulty with urination, skin rash and xerostomia.

Sinus Bradycardia is a condition whereby a person's heart rhythm is slower than normal ( in adults, it could be as slow as 50 beats per minute ). When this occurs, the heart pumps blood too slowly to supply the patient's body system with enough blood. it happens to mostly adults over the age of 60 years. If conditions persist despite respiratory support, atropine is administered.

Atropine is an anticholinergic drug used to increase the heart rate of a person having sinus bradycardia. When administered in large doses, the patient experiences adverse side effects due to the drug's antimuscarinic effects, like blurred vision, constipation and xerostomia.
