Answer:
Evolution is a process that causes an acceleration in genetic change within a population. Allele frequency is the measure of frequency of a certain allele within a population. Allele frequency is an indication that evolution is occurring because a change in allele frequency means a change in the genetics of a population. Also, evolutionary change can’t happen without changes in the allele frequency.

Read the passage. Then explain why the circulatory system of a grasshopper does not need to carry gases to and from the grasshopper's cells.
Passage
The diagram shows part of a grasshopper's respiratory system. Air passes into and out of openings in its sides. These openings are connected to tubes and air sacs that fill with air. The air tubes branch into tiny tubes that spread out and are found close to all cells. So, unlike other animals, the grasshopper does not exchange gases using its circulatory system.
PLS ANSWER ASAP
Answer:
In vertebrates, the circulatory system is responsible for transporting oxygen to all the tissues and removing carbon dioxide from them. ... In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process.

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
Let’s say two items which are balls, are very identical and were dropped at the same times and same height, fell at different times. The pink ball fell first while the blue one fell last. What could have caused the pink ball to fall first?
Answer:
This could mean that the pink ball had a little bit more air in it than the blue ball. They could also have been dropped at the same time, but they were dropped on a hill, and the pink one landed first at the top of the hill, and the blue one landed second at the bottom of the hill.

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.

If there are 3000 calories of energy available at the zooplankton, how much energy will there be at the shark?
Answer:
30 calories of energy
Explanation:
In an aquatic ecosystem, zooplanktons are primary consumer i.e. they feed on primary producers e.g phytoplanktons. They are fed on by smaller fishes e.g tilapia, which in turn is fed on by sharks. Based on this, we have a food chain as follows:
phytoplankton → zooplankton → tilapia fish → shark
From this food chain, it appears that ZOOPLANKTON is a primary consumer while SHARK is a tertiary consumer. Since only about 10% of energy is transferred to each trophic level when organisms feed on one another, if there are 3000 calories of energy available at the zooplankton, the following will be available for sharks:
For secondary consumer = 10/100 × 3000 = 300 calories for tilapia fish
For tertiary consumer = 10/100 × 300 = 30 calories for shark.

Explanation:
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).

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.

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.

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.
