a population ecologist determines the number of a oak trees per square unit in a forest. what is he trying to infer by doing so?

Answers

The population ecologist is trying to determine the density of the oak trees in a forest. It is a part of the job of a ecologist. By detecting the density of the oak trees, an ecologist can easily determine whether the density of the oak trees are decreasing or increasing with time and what are the steps that need to be taken to keep the balance.

Characteristics of animal cells include which of the following? Select all that apply. no cell wall, only plasma membrane

large hypertonic vacuole

no chlorophyll or chloroplasts

cell plate in cell division

cleavage furrow

Answers

Primarily, the properties exhibited by animal cells are:
No cell wall, only plasma membrane (cell walls are a property of plant cells)
No chlorophyll or chloroplasts (animals do not photosynthesize so do not have these organelles)
Cleavage furrow (exhibited during cell replication)

Answer:

no cell wall, only plasma membrane

cleavage furrow

Explanation:

The animal cells are different from the plant cells in many ways. The specific characteristic features of the animal cell include the absence of the cell wall, and the formation of the cleavage furrow during the cell division.

The animal cells only have plasma membrane around them. No large hypertonic vacuole is present. The chlorophyll and chloroplasts are present in the plant cells and not in the animal cells. The cell plate is formed in the plant cells during the cell division. In the animals, a cleavage furrow is formed instead of the cell plate.

Scientists routinely explore whether two different animal species have evolved from a recent common ancestor. _______________ is the LEAST useful technique to help with this determination.a. Analysis of strands of DNA
b. Comparisons of bones and muscles
c. Comparisons of items eaten for food
d. Studies of embryos during development

Answers

The least useful technique in the study is C. Comparisons of items eaten for food. This is the least scientific method of studying two different species because many animals can want the same food and not have any relation with each other. It isn't considered an important factor in determining the similar characteristics of species, especially in terms of genetic makeup.
