Other kinds of white blood cell have a different way of killing

Biology
1 answer:
Katen [24]3 years ago
5 0

Answer:

White blood cells defend against pathogens in three ways. Firstly they release anti-toxins, which neutralize the effect of toxins produced by bacteria. The second way they destroy pathogens is by engulfing/ingesting them.

Hope this helps! Don't forget to give it 5 stars and leave a comment below! Thanks!

The immune system tries to stop invasions by foreign agents by either killing cells directly or by
salantis [7]
Directly The immune system is designed to defend the body against foreign or dangerous invaders. Such invaders include

Microorganisms (commonly called germs, such as bacteria, viruses, and fungi)

Parasites (such as worms)

Cancer cells

Transplanted organs and tissues

To defend the body against these invaders, the immune system must be able to distinguish between

What belongs in the body (self)

What does not (nonself or foreign) normal immune response consists of the following:

Recognizing a potentially harmful foreign antigen

Activating and mobilizing forces to defend against it

Attacking it

Controlling and ending the attack

If the immune system malfunctions and mistakes self for nonself, it may attack the body’s own tissues, causing an autoimmune disorder, such as rheumatoid arthritis, Hashimoto thyroiditis, or systemic lupus erythematosus (lupus).

Can a species switch from being an r-species to a K-species or visa versa?
patriot [66]

Answer:

as causas de las extinción de una especie pueden ser muchas, como la destrucción de su hábitat natural, la caza o captura de animales exóticos, la contaminación, la deforestación (la desaparición de los bosques por la tala de árboles) o el cambio climático, que son consecuencia de la intervención de los seres humanos. Aunque esto también puede relacionarse con distintos fenómenos naturales como inundaciones, incendios, o la llegada de enfermedades.

Explanation:

En algunas ocasiones y por diferentes motivos, las especies de animales empiezan a desaparecer, y esto se conoce como extinción. A pesar de que escuchamos esta palabra muy a menudo, alguna vez te has preguntado, ¿por qué una especie se extingue y qué pasa cuando esto sucede?

A local biologist needs a program to predict population growth. the inputs would be: the initial number of organisms, as an int
Nitella [24]

"A local biologist needs a program to predict population growth. the inputs would be..." The resultant code is

tp=sp

hours = 1

while (hours < t):

tp *= g

hours += r

print("The total population is " + str(int(tp)))

# the call function

<h3>What is a program?</h3>

Generally, a program is simply defined as programming written into a computer or other equipment in order to do a certain task

In conclusion, to write a program that takes these inputs and displays a prediction of the total population must consider  the parameters and the code platform (python), Hence

# on python interface required library is explored

import math

# describe the functions needed

def prediction():

sp = int(input("Enter the initial number of organism: "))

g = float(input("Enter the rate of growth [a real number > 0]: "))

while(g<1):

print ("Invalid.. growth rate.")

g = float(input("Enter the rate of growth [a real number > 0]: "))

r = int(input("Enter the number of hours to achieve the rate of growth: "))

t = int(input("Enter the total hours of growth: "))

tp=sp

hours = 1

while (hours < t):

# the calculation for tp

tp *= g

hours += r

print("The total population is " + str(int(tp)))

#call the created function

CQ

A local biologist needs a program to predict population growth. The inputs would be: 1. The initial number of organisms 2. The rate of growth (a real number greater than 1) 3. The number of hours it takes to achieve this rate 4. A number of hours during which the population grows.                           For example, one might start with a population of 500 organisms, a growth rate of 2, and a growth period to achieve this rate of 6 hours. Assuming that none of the organisms die, this would imply that this population would double in size every 6 hours. Thus, after allowing 6 hours for growth, we would have 1000 organisms, and after 12 hours we would have 2000 organisms. Write a program that takes these inputs and displays a prediction of the total population.
