White blood cells release complementary antibodies to the specific antigen

They attach and clump pathogens together

White blood cells engulf the pathogen phagocytosis occurs

During the primary infection the antibodies slowly increase, peak at around ten days and then gradually decrease.

A second exposure to the same pathogen causes the white blood cells to respond quickly in order to produce lots of the relevant antibodies, which prevents infection.

When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a shor

xenn [34]

Answer:

He will use a radioactive element with a long half life of greater than 1 billion years

Explanation:

Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.

According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

Karo-lina-s [1.5K]

The answer is Maria is having an emotion-focused coping. Emotion-focused methods can support with nearly all stressors.

Emotion-focused coping is well well-matched for stressors that seem uncontainable (ex. a terminal illness diagnosis, or the loss of a loved one).

Explain how the water cycle works and describe how changes to the water cycle can impact the production of hydropower brainliest

maw [93]

Answer:

There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

Which diagram shows the pathway of energy through an ecosystem?

Iteru [2.4K]

Question 1:
The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.

$Producer$
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.

$Producer$ ⇒ $Herbivore$
The carnivore consumes meat, or other animals such as the herbivore. It's the last.

$Producer$ ⇒ $Herbivore$ ⇒ $Carnivore$
Therefore the answer is B.

Question 2:
I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.
