What else can I help you with?
Are there many parts of the body that viruses can't invade?
No.
There are many parts of the human body that viruses cannot invade?
True
There are many parts of the body that viruses cannot invade?
True
What type is likely to invade other body tissues and spread to other (distant) parts of the body?
Cancer cells
How does the number of body cavities of nematodes compare with that of flatworms?
Nematodes have a pseudocoelom (a body cavity that is not completely lined by mesoderm), whereas flatworms have an acoelomate body plan (lack a body cavity). This means that nematodes have a body cavity, while flatworms do not have a true body cavity.
Nematodes have a fluid-filled pseudocoel that serves as a skeleton?
No, nematodes do not have a fluid-filled pseudocoel as a skeleton. Nematodes have a hydrostatic skeleton, which is a combination of fluid pressure and muscles that provide support and movement. The pseudocoel is a body cavity that houses the internal organs in nematodes.
What type of neoplasm is likely to invade other body tissues and spread to other parts of the body?
Malignant neoplasms, such as carcinomas and sarcomas, have the propensity to invade surrounding tissues and metastasize to other parts of the body through the bloodstream or lymphatic system. This invasive behavior distinguishes them from benign neoplasms, which typically remain localized and do not spread to distant sites.
What is a tumor called if it can invade and destroy the surrounding healthy tissue?
A tumor that can invade and destroy surrounding healthy tissue is called malignant or cancerous tumor. This type of tumor has the ability to spread to other parts of the body.
How does the nematoda body plan differs from that of annelida?
Nematodes do not have segmented bodies like annelid do.
Which one between longitudinal and circular muscle which is absent in nematodes?
In nematodes, circular muscle is absent. Nematodes possess only longitudinal muscle, which allows for their characteristic thrashing movement. This adaptation is part of their unique body structure, enabling them to navigate through their environments effectively.
Which phase best describes cancer?
Cancer is best described as an uncontrolled growth of abnormal cells that can invade nearby tissues and spread to other parts of the body.
Why are cancer cells harmful to the body?
Cancer cells are harmful to the body because they grow uncontrollably, invade surrounding tissues, and can spread to other parts of the body, disrupting normal bodily functions and potentially causing organ failure.
