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.

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.

Which of the following is true regarding Darwin's theory of evolution?
A. Acquired traits are always passed on to the offspring
B. Organisms develop favorable adaptations based on a need
C. Pure chance determines which species evolve
D. Individuals pass on adaptations to their offspring, due to natural selection
Answer:D
Explanation:
Evolution
Individuals pass on adaptations to their offspring, due to natural selection. The correct option is D.
What is Darwin's theory of evolution?The English naturalist Charles Darwin and others developed the Darwinism theory of biological evolution, which contends that all species of organisms arise and develop through the natural selection of minute, inherited variations that improve the individual's capacity for competition, survival, and reproduction.
Darwin claimed that all species share a common origin, that species can change through time, and that new species develop from existing ones.
Charles Darwin, a naturalist of the 19th century, investigated the theory of natural selection.
Natural selection provides an explanation for how a species' genetic features might evolve through time. This could result in speciation, or the creation of a new, separate species.
Thus, the correct option is D.

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.

Why is the classification species not considered a group
Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups.
There are five kingdoms: • Animals • Plants • Fungus • Protist • Bacteria Scientists classify animals together because they have similar characteristics such as they eat other living things and have many cells. As you can see from the chart, kingdoms are divided into groups called phyla.

The classification of species is not considered a group because each species is a separate type of organism. The correct option is D.
What are groups and species?Group is the level of taxonomy in which the organism is present, which has someone's character. Like in the insect group, all insects are present.
Species are the largest level of the taxonomy of the organism. Species are animals or plants or individuals that have the same characteristics and those that can mate with each other and form fertile offspring.
Groups contain numerous species. Like in insects, the insects contain numerous insects that are very different from each other. Like, bees and beetles are very different from each other.
Thus, the correct option is D. Each species is a separate type of organism.

How many nucleotides are required for a 459-amino acid polypeptide? Just enter the
number.
Answer:
The correct answer is 1377.
Explanation:
Peptides and proteins are made in the process of Translation. For this to happen, a molecule of mRNA containing a nucleotide sequence is read by a structure called ribosome. Each group of three nucleotides from the mRNA form a codon, and each codon has an anticodon in the tRNA molecule that will ultimately code for a specific amino acid (except for stop codons -when they appear in the sequence, translation stops-). Taking all of this into consideration, if 3 nucleotides lead to 1 amino acid, to have a 459-amino acid polypeptide it would require 1377 nucleotides (without counting the 3 nucleotides from the stop codon).

Explanation:

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

Make sure you give a full, detailed answer, not just one sentence.
Answer:
Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. ... As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!
