An important challenge to traditional (pre-1860) ideas about species was the observation that seemingly dissimilar organisms such as hummingbirds, humans, and whales have similar skeletal structures. This most directly suggested to biologists that _____.

Answers

Answer 1
Answer:

Answer:

Dissimilar organisms might have evolved from a distant, common ancestor.

Explanation:

First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.

Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.

WHAT HAPPENS TO THE CARBON ATOM DURING PHOTOSYNTHESIS

Answers

 the carbon dioxide that is,CO2 is split into carbon and oxygen ,the some of the oxygen is released and the carbon is mixed with water that is H20,if you construct and equation for the reaction between carbon and water you will see that the product is glucose(sugar) 
that is why we say that during photosynthesis plants take in water and carbon dioxide in order to manufacture their food(which is glucose) and to release oxygen

Which macronutrient is vital for every function of the body? A.
water
B.
fats
C.
proteins
D.
carbohydrates

Answers

The correct answer is Water.

Water is the most important macronutrient for performing all the vital functions of the body. It does not provides energy to the body. The main function of water is to provide a medium for all the metabolic processes that takes place in our body. It helps in absorption of macronutrients but has no nutritive value of its own.Elements such as chloride and fluoride reach the body through this medium.

Which sentence lists events in the cell cycle in correct order, from earlier to later?The chromosomes become longer and thinner; spindle fibers attach to the centromeres.
The nuclear membrane reforms; the chromosomes align in the middle of the cell.
The chromosomes replicate; the nuclear membrane dissolves.
The sister chromatids are separated; the chromosomes condense.
Which of the choices below describe one similarity between meiosis II and mitosis?
In both processes, sister chromatids are pulled apart.
Homologous chromosomes separate in both stages.

Answers

The chromosomes become longer and thinner; spindle fibers attach to the centromeres.

Cell cycle refers to the process by which the cells undergo several DNA duplication activities creating daughter cells. It is very important because without the cell cycle there would be no reproduction of the body cells and that would lead to  dysfunctional body organs.

Homeostasis will be MOST affected by the removal of the

Answers

The answer is Cell membrane

Homeostasis is maintaining a precise environment within organism.

Meanwhile, Cell Membrane is responsible to controls whats go in and go out within cells.

Therefore, Homeostais really depend on the activity of Cell Membrane, which is why is will heavily affected by cell membrane removal

Answer:

Cell Membrane

Explanation:

The cell membrane decides what comes in and goes out of the cell.  If removed waste, liquids or germs could get in and disrupt the cell's homeostasis
