a ________ biopsy is the aspiration of a core of tissue for microscopic examination.
A core biopsy is the aspiration of a core of tissue for microscopic examination.
During a core biopsy, a needle is inserted under the skin to remove a sample of tissue from a tumour or lump. The tissue is then checked for any anomalies under a microscope.
When a worrisome mass is discovered, such as a breast lump or an enlarged lymph node, or when an anomaly is observed on an imaging test, such as an x-ray, ultrasound, or mammogram, a core biopsy may be carried out.
Due to the use of a local anaesthesia, core biopsy is a more intrusive process than fine needle aspiration biopsy. However, compared to a surgical biopsy, it is speedier and less intrusive. The results of a core biopsy might sometimes foreclose the need for surgery.

across all cancers, _______ are due to inherited genetic mutations. 1-2% 5-10% 15-20% 25-30%
Across all cancers, 5-10% are due to inherited genetic mutations.
Inherited genetic mutations are changes in DNA that are passed down from one generation to another. These mutations can increase an individual's risk of developing cancer. However, not all individuals with inherited mutations will develop cancer, as other factors such as lifestyle, environment, and chance also play a role in cancer development.
It is important to note that the majority of cancer cases are not caused by inherited genetic mutations, but rather by acquired mutations that occur during a person's lifetime. Acquired mutations can result from exposure to harmful substances such as tobacco smoke, radiation, or certain chemicals, as well as normal aging processes.
While the percentage of cancers due to inherited genetic mutations may seem relatively small, understanding the role of these mutations in cancer development can help identify individuals at a higher risk and facilitate early detection and intervention. Genetic counseling and testing can provide valuable information for individuals with a strong family history of cancer or known inherited mutations. This information can guide personalized prevention and screening strategies, ultimately reducing the overall cancer burden.

during which stage of pregnancy does a pregnant woman usually gain a total of two-to-four pounds?
Explanation:
first, bc then is the baby already there
During the first trimester of pregnancy, which spans from week 1 to week 12, a pregnant woman usually gains a total of two-to-four pounds. This weight gain is mostly due to the growth of the uterus, increased blood volume, and hormonal changes in the body. In the early weeks of pregnancy, the fetus is still developing and is very small, which means that there isn't much weight gain from the baby yet.
Instead, the mother's body is adjusting to support the pregnancy, which can lead to mild weight gain. However, it's important to note that every woman's pregnancy is unique, and weight gain can vary depending on factors such as pre-pregnancy weight, overall health, and the individual needs of the growing fetus. Pregnant women should consult with their healthcare provider to determine what is a healthy amount of weight gain for their specific pregnancy.
Weight gain in the first trimester is typically due to increased blood volume, amniotic fluid, and the growth of the uterus, rather than the baby itself. It is important for pregnant women to maintain a healthy diet and lifestyle to support the growth and development of their baby throughout all stages of pregnancy.

gender differences -- not sex differences -- in sports are determined most by which factor(s)?
Gender differences in sports are primarily determined by sociocultural factors rather than biological factors.
These sociocultural factors encompass societal expectations, stereotypes, and the way children are raised with regard to gender norms.
Societal expectations play a significant role in influencing the types of sports individuals engage in, as well as their level of involvement. Traditionally, certain sports are seen as more "masculine" or "feminine," which can lead to biases in participation and performance. For example, men may be encouraged to engage in contact sports like football, while women might be steered towards gymnastics or dance.
Stereotypes about gender can also impact an individual's perception of their athletic abilities and the opportunities available to them. These stereotypes can discourage people from participating in sports that are not deemed appropriate for their gender, limiting their potential for growth and development.
Lastly, upbringing plays a crucial role in shaping gender differences in sports. From a young age, children are often exposed to specific gender norms that influence their interests, behaviors, and self-perception. These norms can impact their choice of sports and their overall involvement in physical activities.

the vaccine against smallpox developed by edward jenner is an example of a(n) ________ vaccine.
The vaccine against smallpox developed by Edward Jenner is an example of a(n) attenuated vaccine.
An attenuated vaccine, often known as a live attenuated vaccine (LAV), is a vaccine made by lessening a pathogen's severity while keeping it alive (or "live"). An infectious agent undergoes attenuation, which changes it so that it loses its virulence or becomes harmless. These vaccines stand in contrast to inactivated vaccinations, which are created by "killing" the virus.
A robust and sustained immune response is elicited by attenuated vaccinations. Attenuated vaccinations result in a higher immune response than inactivated vaccines with a quicker start of immunity. Attenuated vaccinations work by triggering the production of antibodies and memory immune cells by the body in response to the particular infection that the vaccine is designed to protect against.

marcia's baby boy weighed 8 pounds at birth. how much should he weigh by 4 months of age?
Marcia's baby boy should weigh approximately: 14 pounds by 4 months of age.
Please note that this is just an estimate, and actual weight may vary depending on individual growth patterns and factors. It's essential to consult with a pediatrician for more accurate and personalized information.
To determine how much Marcia's baby boy should weigh by 4 months of age, we need to consider the average weight gain for infants during their first few months. The terms we will use in the answer are baby boy, 8 pounds, birth, and 4 months of age.
On average, a baby boy tends to gain about 1 to 2 pounds per month in the first few months. Since Marcia's baby boy weighed 8 pounds at birth, we can calculate his approximate weight at 4 months of age as follows:
1. Determine the average monthly weight gain (we'll use 1.5 pounds as an average between 1 and 2 pounds).
2. Multiply the average monthly weight gain by the number of months (4 months).
3. Add the result to the baby's initial weight at birth.
Step-by-step calculation:
1. Average monthly weight gain = 1.5 pounds
2. Weight gain over 4 months = 1.5 pounds x 4 months = 6 pounds
3. Baby's weight at 4 months of age = 8 pounds (birth weight) + 6 pounds (weight gain) = 14 pound

the heart is situated within the medial section of the thoracic cavity known as the ________.
The heart is an essential organ that plays a crucial role in the circulatory system. It is situated within the medial section of the thoracic cavity known as the mediastinum. The mediastinum is the central compartment of the thoracic cavity, located between the lungs and containing important structures such as the heart, major blood vessels, esophagus, trachea, and thymus gland.
The heart is enclosed by a double-layered sac called the pericardium, which provides protection and support. The pericardium has two layers: the outer fibrous pericardium and the inner serous pericardium. The serous pericardium is further divided into the parietal layer, which lines the fibrous pericardium, and the visceral layer, which covers the heart's surface.
The primary function of the heart is to pump blood throughout the body, supplying oxygen and nutrients to tissues and removing waste products. The heart achieves this through its four chambers: the left and right atria and the left and right ventricles. The atria receive blood from various parts of the body, while the ventricles pump it to different regions.
Overall, the heart's location within the mediastinum allows it to efficiently perform its crucial role in the circulatory system, maintaining the body's overall health and functionality.
