Answer:
<em>Evolution</em>
Explanation:
Evolution can be described as the changes which occur in a population over a period of time. Over a period of time, organisms tend to evolve those characteristics which make them better adapted to live in an environment. Such changes which occur over a long period of time are termed as evolution. Charles Darwin was the scientist to bring forward the theory of evolution.
The change in the tail length of a rat over a course of many years is an example of evolution.
Answer:
chloroplast: makes food for plant cells, photosynthesis
mitochondria:produces energy the cell needs to carry out its functions; release energy
vacuole: stores food, water, and waste
lysosome: found mainly in animal cells, digests old cell parts
endoplasmic reticulum: carries proteins and other materials from one part of the cell to the other
cytoplasm: gel -like fluid where the organelles are found
nucleolus: makes ribosomes, center of the nucleus
ribosome: makes proteins
cell membrane:controls
Explanation:
I'm pretty sure the answer is D based on the info above,and because its the only one that has the correct information about the cell parts
hope its correct
Answer:
A: Suited for their environment
Explanation:
You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.
Hope this helped!
Answer:
Apply the principle of parsimony
Explanation:
A cladogram is used to show or illustrate hypothetical speciation and relationships between species. They are commonly used to classify animals.
The principle of parsimony argues that the simplest of competing explanations is most likely to be correct.
In order to construct a cladogram that best reflects the evolutionary relationship of a group of species. Application of the principle of parsimony will help in deciding which tree is most likely to have occurred based on the fewest character state changes.
The options attached to this question are given below:
A. contains mostly needle-leaved evergreen trees.
B. is home to herds of giraffes, zebras, and wildebeests.
C. receives less than 25 cm of precipitation per year.
D. has low-growing; touch shrubs and rock, dry soils
.
ANSWER
The correct option is D.
The chappral biome is one of the most widespread biome in the world, it can be found on almost all continents. The major characteristic of the biome include the following:
It has both forest and grassland,
It has two major seasons, winter and summer; the summer season is usually very dry and last for about five months.
The dry summer makes the biome sensitive to fire outbreak, which is a common occurrence there.
The amount of rain available to the biome is about 10 - 17 inches per year and is only able to support shrubs growth, only few trees can be found in the biome.
The biome can be a plain, a rolling hill or a mountain and the soil is usually very dry.
