Chordate embryos develop a notochord along the dorsal side. this position is located at the _____ of the embryo.

Answers

Answer 1
the answer is the BACK of the embryo
Answer 2

Answer:

this position is located at the back of the embryo.

Explanation:

The notochord, also called the dorsal cord, is a stick formed by cells that is located on the back of the embryos of the chordates, that is, on the back of the embryo. This structure originates from the differentiation of the mesoderm, and its function is to support the nervous tube. In most chordates, this structure disappears at the end of the embryonic phase.

The dorsal nervous system, also known as the dorsal nervous tube, originates from the ectoderm of the embryo (forming the nervous tube) and is located in the dorsal region of the body, under the embryonic notochord. It is from this tube that the nervous system will be formed. In the anterior part of the embryo's body there is a dilation of this cord, forming the brain vesicle, which in vertebrate animals will give rise to the brain.

Hair loss is a side effect of which of the following types of cancer treatment?

Answers

Chemotherapy causes hair loss.

The Hair loss is a side effect the main types of cancer treatments associated with hair loss include chemotherapy, radiation therapy, and targeted therapy.

Hair loss, also known as alopecia, is a common side effect of several cancer treatments, primarily due to their impact on rapidly dividing cells, including those in hair follicles.

The main types of cancer treatments associated with hair loss include chemotherapy, radiation therapy, and targeted therapy.

1. Chemotherapy: Many chemotherapy drugs work by targeting fast-growing cells, which unfortunately includes not only cancer cells but also healthy cells like those in hair follicles.

This often results in diffuse hair thinning or complete hair loss.

The extent and pattern of hair loss can vary depending on the specific chemotherapy drugs used.

2. Radiation Therapy: Hair loss can occur when radiation therapy is directed at the head or scalp.

However, the extent of hair loss may depend on the dosage and the specific radiation therapy techniques employed.

3. Targeted Therapy: Some targeted therapy drugs, while more selective in their action against cancer cells, can still affect hair follicles, leading to hair thinning or loss in some cases.

It's important to note that not all cancer treatments cause hair loss, and the likelihood and severity of hair loss can vary depending on the specific treatment regimen, dosage, and individual factors.

Patients undergoing cancer treatment should discuss potential side effects, including hair loss, with their healthcare team and explore options for managing and coping with this side effect, such as scalp cooling systems or wigs.

When experiencing a fever and runny nose, it's imperative to stay home, practice good hygiene by frequently washing hands, and cover your mouth with a tissue when sneezing or coughing to prevent spreading germs.

Explanation:

When experiencing symptoms such as a fever and runny nose, the best course of action is to avoid contact with others to prevent the spread of infection. This means not going to work or school and seeking medical advice if symptoms persist. It's essential to practice good hygiene habits, such as washing hands frequently and covering your mouth and nose with a tissue when you sneeze or cough, to control the transmission of diseases.

Hand washing for at least 20 seconds with soap and warm water is crucial, especially after sneezing, coughing, or blowing your nose. If medical attention is needed due to severe symptoms such as fever over 101, swollen glands, or prolonged illness, consult a healthcare provider promptly.
