I would say either C or D beside A say most living things are made of cells. No, all living things have cells. And B is right but C or D makes more sense.

Shtirlitz [24]

Full question:

Drag each label to the correct location on the chart. Based on the number of offsprings they produce at one time, organisms are classified into two categories many offsprings at once and a few at a time. Sort the characteristics based on the category they describe.

A.Low percentage of offspring reach adulthood,

B.limited parental involvement,

C.High percentage of offspring reach adulthood,

D.Rapid maturation,

E.Parental care observed,

few offspring at once vs many offspring at once.

Answer:

At the same time, there are a few offspring

C. A high proportion of offspring grow up to be adults.

E. Observed parental care,

At the same time, many offspring

A. Only a small fraction of offspring grow up to be adults.

B. minimal parental participation;

D. Rapid maturation.

Few offspring at a time have a high percentage of offspring reaching adulthood. If a large percentage of offspring reach adulthood, the offspring are likely to be few and well cared for.

<h3>What is parental care?</h3>

Parental care is seen to be unique to only a few offspring at a time. If the parents provide good care to their children, the offspring are likely to be few. It will be easier for the parent organism to care for a small number of children at once.

Many offspring at once have a low percentage of offspring reaching adulthood. Because there are so many kids at once, competition for room and food, as well as a lack of care, only a small percentage of them will reach adulthood.

Many offspring have limited parental participation at the same time. Because there were so many kids at the same time, the competition for parental care among the offspring would be strong. The parents' organism will be unable to care for the large number of children.

Rapid maturation is unique to several offspring at the same time. In order to survive, the organism will have to mature quickly. Due to the large number of children, survival will be determined by the fittest. The ability of the children to mature quickly will be aided by the survival of the fittest trait.

How are extrusive and intrusive rocks alike

Veseljchak [2.6K]

Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form.

Explanation:

intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and periodontist. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals.
