When Charles Darwin published his radical theory of evolution by natural selection in 1859 it was attacked by many early biologi
irina1246 [14]

Answer:

Empirical evidence of his ideas

Explanation:

The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.

Which substance on the plasma membrane helps identify chemical signals from outside the cell?
nikdorinn [45]

Answer:

The correct answer is carbohydrate chain.

Explanation:

Plasma membrane contain three types of protein  a peripheral protein b transmembrane protein and c GPI anchored protein.

    Some membrane protein basically peripheral proteins contain oligosaccharide chain arranged towards the extracellular region of the plasma  membrane with respect to the surface of that glycoprotein.

   The oligosaccharide chain of glycoprotein play an important role in to identify signals from outside the cell.These signals may include the entry of virus particles inside our body,protein targeting etc.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
umka21 [38]

Answer: DESERT

Explanation:

Adaptation can be defined as the modification in the form, structure, function and behaviour of organisms in a habitat which enables them to live successfully and reproduce.

Desert is one of the types of the world biomes that is characterized with little or no rain and to extreme temperatures. Organisms, which includes plants and animals, must show some level of adaptation to able to survive the harsh environment.

The type of PLANTS which can survive in desert environment are called the XEROPHYTES. They show the following adaptations:

--> The roots are well developed: they grow down to great depths and branch extensively in order to absorb water

--> they possess swollen stems which contains water storage cells.

--> they have reduced leaves, for example in cacti in the form of spines, which helps to reduce water loss through transpiration.

The type of animal that survive in desert environment spend the hot dry seasons in a sleep-like torpid state called aestivation. This is so in order to avoid the heat. Their body size is usually small and less bulky: greater surface area in relation to body volume, thus enhancing heat loss from the body.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.

3. How do nutrients and other materials move in fungi?
12345 [234]

Answer:

Nutrients and other materials from the environment are absorbed through mycelia. The branching mycelia have a high surface-area-to-volume ratio which allows the  absorption of nutrients to be more efficient. Fungi may even digest nutrients by releasing enzymes into the environment.

Explanation:

I have a strange feeling that this isn't the answer you were looking for.
