Lymph ______ are found throughout the body and are a signal of a disease, infection, or problem if they become and remain swollen for long periods of time. ______ are pathogens that cannot be killed with antibiotics because they are non-living. They take over cellular organelles to replicate and spread. Because they are also eukaryotes with their own cell membranes and membrane-bound organelles, ______ are often difficult to combat with medicines. A cell signal called ______ is produced by mast cells. These molecules cause more fluid to spread to an infected area. _______ are the types of cells that produce antibodies. All pathogens have unique identifying molecules on their surfaces called ______. Antibodies bind to these, and targeting the pathogen to be destroyed by the immune system. ______ is a non-specific response to disease, in which the body temperature rises. Respond to the following based on your reading. Describe the steps that occur, in order, to trigger an inflammatory response to a paper cut.
Answer:
Lymph nodes are found throughout the body and are a signal of a disease, infection, or problem if they become and remain swollen for long periods of time. Bacteria are pathogens that cannot be killed with antibiotics because they are non-living. They take over cellular organelles to replicate and spread. Because they are also eukaryotes with their own cell membranes and membrane-bound organelles, viruses are often difficult to combat with medicines. A cell signal called the FcϵRI receptor is produced by mast cells. These molecules cause more fluid to spread to an infected area. Lymphocytes are the types of cells that produce antibodies. All pathogens have unique identifying molecules on their surfaces called antigens. Antibodies bind to these and targeting the pathogen to be destroyed by the immune system. Fever is a non-specific response to disease, in which the body temperature rises. Respond to the following based on your reading. Describe the steps that occur, in order, to trigger an inflammatory response to a paper cut.
Answer:nodes
Viruses
fungi
histamine
B-cells
antigens
Fever
When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.

How do the lungs help us breathe? They pump oxygen through the blood vessels and carbon dioxide into the heart. They take in oxygen as we inhale and release carbon dioxide as we exhale. They take in oxygen as we inhale and release nutrients as we exhale. They take in nutrients as their muscles contract and release carbon dioxide as they rel
Explanation:
Your lungs deliver oxygen and remove carbon dioxide from your blood in a process called gas exchange. Gas exchange happens in the capillaries surrounding the alveoli, where the oxygen that is breathed in enters the circulatory system and carbon dioxide in the blood is released to the lungs and then breathed out.
Answer:
Your lungs deliver oxygen and remove carbon dioxide from your blood

A. Cellular respiration shuts down during the day while
photosynthesis occurs, and then photosynthesis shuts down at night while cellular respiration occurs.
B. Both cellular respiration and photosynthesis rates cycle up and down in similar patterns over a 24-hour cycle.
C. Oxygen levels oscillate as the light-dependent reactions of photosynthesis take place during daylight and light-independent reactions take place during nighttime.
D. Cellular respiration remains constant, while photosynthesis cycles between a very high rate in the light and zero in the dark.
Answer:
Option-D
Explanation:
Cellular respiration and photosynthesis are the two main physiological process which drives the life on Earth. Photosynthesis process leads to the synthesis of Glucose whereas Cellular respiration breakdown the Glucose molecule to form ATP molecules.
In plants, the photosynthesis process occurs in green leaves whereas cellular respiration occurs in every cell of the plant inside the mitochondria.
In the given question, the graph shows:
1. The absorption of oxygen till 6 am which is required during cellular respiration.
2. After 6 am, the level of oxygen production becomes more than oxygen absorption till 6 pm.
3. After 6 pm, no sunlight is available therefore photosynthesis does not occur. After this, the rate of cellular respiration increases that is oxygen is taken in.
Thus, Option-D is correct.

What is the net primary productivity of the tropical rainforest if gross primary productivity in a tropical rainforest is 6 kcal/m2/yr and respiration is 3 kcal/m2/yr? A) 1.5 kcal/m2/yr B) 2 kcal/m2/yr C) 3 kcal/m2/yr D) 4 kcal/m2/yr
Answer:
Net primary productivity of the tropical rain-forest = 3 kcal/m2/yr
Explanation:
Given:
Gross primary productivity in a tropical rain-forest = 6 kcal/m2/yr .
Respiration = 3 kcal/m2/yr
Find:
Net primary productivity of the tropical rain-forest
Computation:
⇒ Net primary productivity of the tropical rain-forest = Gross primary productivity in a tropical rain-forest - Respiration
⇒ Net primary productivity of the tropical rain-forest = 6 kcal/m2/yr - 3 kcal/m2/yr
Net primary productivity of the tropical rain-forest = 3 kcal/m2/yr
Which process occurs in yeast to make bread rise?
aerobic respiration
lactic acid fermentation
alcoholic fermentation
hydrochloric acid fermentation
Answer:
The answer is option 3.
Explanation:
Yeast respire glucose anaerobically to produce alcohol and bubbles of carbon dioxide. Carbon dioxide is the gas which makes the bread rises.
So it is an alcoholic fermentation.
The equation for fermentation :
Glucose → Alcohol + Carbon dioxide

Which of the following explains the process of evolution?
a process of change in a population through genetic variati
the genetic variation within a species
a change in one species that results from a change in a dife
DONE
Answer:
A process of change in a population through genetic variation.
Explanation:
Evolution is the process of change in heritable characteristics of populations of organisms over several generations as it allow natural selection in it.
Genetic variation which refers to differences in gene frequencies is an important force in evolution which relies of natural selection to cause an increase or reduce gene frequencies in a population. Evolution lead to changes in genetic material of populations over time which make them to develop genes that will allow them to adapt to their environment for survival and reproduction.
Answer: A: process of change in population
