Answers

Answer 1

Explanation:

they filter out pathogens they mantain the population of mature lymphocytes
Answer 2

The secondary lymphoid organs are the lymph nodes and spleen, which keep the number of mature lymphocytes in check and filter out infections, hence option B is correct.

What is secondary lymphoid tissue?

The thymus, where T-lymphocytes develop, and red bone marrow, which produces blood and immune cells, are the two main lymphoid organs.

Lymphocytes are also stimulated in secondary lymphoid tissues. Peyer's patches, tonsils, spleen, lymph nodes, and mucosa-associated lymphoid tissue are among them (MALT).

Numerous lymphocytes, a kind of white blood cell, are found in lymph nodes. They produce substances that stimulate other immune system components and aid in the battle against the illness. This is the reason why when you have an infection, your lymph nodes expand.

Therefore, the lymphocytes in your lymph nodes grow if you have an infection, hence option B is correct.

Which types of birth control are the most effective?​

Answers

Answer:

The kinds of birth control that work the best to prevent pregnancy are the implant and IUDs — they're also the most convenient to use, and the most foolproof. Other birth control methods, like the pill, ring, patch, and shot, are also really good at preventing pregnancy if you use them perfectly.

Paragard is over 99% effective—more effective than any other hormone-free birth control method*—and most hormonal methods. In fact, the American College of Obstetricians and Gynecologists (ACOG) recommends Paragard as one of the most reliable ways of preventing pregnancy.

In which of Piaget’s stages does a child begin to pretend and ask questions? A. concrete operational B. sensorimotor C. preoperational D. formal operational

Answers

Answer:

C

Explanation:

The preoperational period is divided into two stages: The Symbolic Function Substage occurs between 2 and 4 years of age and is characterized by the child being able to mentally represent an object that is not present and a dependence on perception in problem solving. The Intuitive Thought Substage, lasting from 4 to 7 years, is marked by greater dependence on intuitive thinking rather than just perception (Thomas, 1979). At this stage, children ask many questions as they attempt to understand the world around them using immature reasoning. Let’s examine some of Piaget’s assertions about children’s cognitive abilities at this age.
