1 Earthquakes - swarms of earthquakes happen first.

2 Gas Emissions - gas begins to emit from the volcano.

3 Ash/steam venting - ash and steam begin to fill the air.

4 Lava Dome Buildup - lava builds up, getting closer to the dome of the volcano.

5 Dome Collapse - the dome collapses, leaving the lava free to burst out.

7 Pyroclastic Eruption - finally, the volcano erupts.

An organism takes care of its young and produces few offspring. What type of organism is this?

erma4kov [3.2K]

Answer:

K-strategists

Explanation:

Reproductive pattern in organisms can be typically categorised into two:

1. K- Strategy

2. R- Strategy

K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.

R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.

Examples of K-strategists are elephants and man

Examples of R-stategists are grasses and microbes.

What is endosperm? via cotyledons, a source of food for the embryo the leaves that are a part of the embryo the male portion of

AfilCa [17]

Answer: Option A

Explanation:

An endosperm is defined as the tissue which are produced inside the seeds during fertilization. As the endosperm surrounds the embryo, it acts as the food storage for the embryo and provide nutrition.

During embryo development , endosperms supports enlargement of cotyledons which helps in storage function and stores fats and starch and provide nourishment to the embryo.

for example cereal crops or grains are primarily endosperm which stores fat and starch and are edible fruits.

Hence, the correct option is A, endosperm can be a cotyledon which functions as a source of food for embryo.

The same tom and jane's blood donations are sent to a processing center where the blood cells are separated from the plasma in e

Solnce55 [7]

Since the blood is already separated form the cellular components and the plasma, blood typing can be a challenge if the medical technologist does not know the theory. Antigens are membrane proteins on the red blood cells. There are 2 types of antigens namely the A antigen and B antigen. Blood types are according to the antigen present in the red blood cells. Blood type O has no antigens in the red cell surface, blood type A has A antigen, blood type B has B antigen, and blood type AB has both A and B antigens. In identifying the antigen, the researcher should extract the cellular components rather the plasma. The plasma, on the other hand, contains antibodies.
