Explanation:
Thomas Malthus was an economist who influenced Darwin's developing theory of evolution. Malthus observed that the birthrate among humans exceeded the death rate. If this trend continued, soon there would not be enough resources to support human population growth. He reasoned that the only things capable of stopping human population growth were famine, disease, and war. Darwin applied this thinking to animals and plants as well, noting that far more offspring were produced than survived to a reproductive age. 2. How did Charles Darwin build on the work of Thomas Malthus to develop the idea of evolution by natural selection
Answer:
The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.
Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

Which statement describes both a positive impact and a negative impact associated with the effects of nitrogen-enhanced fertilizers?
They increase polluted runoff and damage drinking water.
They increase plant growth and damage drinking water.
They increase denitrifying bacteria and increase plant growth.
They increase both limiting resources and denitrifying bacteria.
Answer:
Option B
Explanation:
Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body
Hence, option B is correct

What Is the location of the instructions that code for traits?
Answer:
Traits are coded for in DNA, specifically in genes.
Explanation:
DNA, as you probably already know, is made up of long sequences of nucleotides of A's, T's, C's, and G's. When transcripted into mRNA and translated into proteins in ribosomes, the order of these nucleotides signal which amino acids to produce for the protein. Proteins are extremely important and have many roles throughout the body, which means they actualize the code of DNA into physical traits. I hope this helped.

A partir del concepto de osmorregulación cual es la regulación hídrica y salinas en peces de agua dulce y salada
Answer:
Absorben o excretan agua salada para mantener la homeostasis.
Explicación:
La regulación hídrica y salina en peces de agua dulce y salada se realiza según las condiciones ambientales. Los peces pueden pasar mucha orina muy diluida en la que hay menos solutos o sales, y logran el equilibrio de electrolitos en el cuerpo mediante el transporte activo de sales a través de las branquias. En un ambiente marino hipertónico, los peces de agua salada comienzan a beber agua de mar y mantienen el equilibrio electrolítico mientras excretan el exceso de sales a través de sus branquias y su orina.
Which of the following statements is NOT true of photosynthesis?
Photosynthesis captures and uses energy from the Sun for daily activities.
Photosynthesis captures and stores energy from the Sun.
Photosynthesis requires carbon dioxide and water.
Photosynthesis stores the energy from the Sun in molecules of sugar.
Answer:
photosynthesis captures and uses energy from the sun for daily activities
Explanation:
In the carbon cycle, atmospheric carbon dioxide is converted into organic material by which process? a) transpiration b) cellular respiration c) decomposition d) photosynthesis
Answer:
The correct answer is d) photosynthesis
Explanation:
Photosynthesis is the process by which plants transform inorganic matter from their external environment into organic matter that they will use for their growth and development. It basically consists of the production of sugars from C02 (carbon dioxide) in the air, minerals and water with the help of sunlight. In this reaction, oxygen molecules are released and carbohydrates are fixed in the plant. Plants absorb sunlight through a pigment called chlorophyll. Not only can plants fix CO2, so do certain bacteria and green algae. Photosynthesis is conditioned by internal plant factors and external or environmental factors.

What is Transpiration?Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
Transpiration is essentially evaporation of water from plant leaves. Transpiration is important because water is needed for photosynthesis and because water cools a plant off.
Thus, option "C" is the correct answer.

Answer: Differentiation allowed the brain and kidney cells to become specialized for the structures and functions they possess.
Explanation:
Differentiation allowed the brain and kidney cells to become specialized for the structure and functions they possess.
CELLULAR DIFFERENTIATION:
Cellular differentiation is the process whereby an unspecialized cell (stem cell) gives rise to a cell that is more specific in function. Stem cells are said to be totipotent meaning that they are capable of dividing into special (differentiated) cells. Cell differentiation is brought about by gene expression mechanism in cells i.e. some genes are expressed in some cells and not expressed in others. Since all cells contain the same type of gene, they are bound to function the same without difference in the type of gene expressed in them.Cell differentiation allows different cells in a multicellular organism to contain different structures and ultimately perform different functions. Therefore, differentiation allowed the brain and kidney cells to become specialized for the structure and functions they possess.Learn more at: https://brainly.com/question/18639909?referrer=searchResults
Two distinct bands appear in a single lane at the completion of an SDS-PAGE analysis of an unknown protein. Select one: a. These bands represent two subunits of a homodimer. b. Each band represents a different sized subunit of a multimeric protein. c. Each band represents a protein subunit with different charge to mass ratio. d. These bands represent two subunits of a heterodimer. e. These bands represent two separate subunits of identical size.
Answer:
b. Each band represents a different-sized subunit of a multimeric protein.
Explanation:
SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.
The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.
SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be. The speed of displacement in the electromagnetic field is inversely proportional to the protein size.
