Answer:

Los fotorreceptores son neuronas especializadas sensibles a la luz, localizadas en la retina externa de los vertebrados. Los conos y bastones son unas de las células mas especializadas y complejas de nuestro cuerpo. Realizan la conversión de la luz en impulsos nerviosos que el cerebro transforma en imágenes.

Over the course of more than a century, the worlds economy relies on capitalism. This is the idea of starting businesses and investing in them to make them grow faster and eventually make more money. However, global warming is a factor that pushes against the idea of capitalism because it negates the idea of using industrial factories. With the rise of global warming, the less factories our world can support leading to the fall of capitalism worldwide.

Hazardous waste can be criminal to our society because it pollutes every part of the ecosystem, including air, water, and land. By doing so, it can create a huge problem. What it does is it effects the natural lifestyle for many animals that make up the ecosystem and can ultimately result in a disaster among all life on earth.

1. Nucleotides: A phosphate group, a 5-carbon sugar, and a nitrogenous base are the three components of a nucleotide. Adenine, cytosine, guanine, and thymine are the four nitrogenous bases in DNA. Instead of thymine, uracil is found in RNA. The genetic material of all known living creatures is made up of nucleotides in a chain.

2. Genes: A gene is a small segment of a lengthy DNA double helix molecule that consists of a linear base pair sequence. A gene is any portion of DNA that contains instructions that allow a cell to generate a specific product – usually a protein, such as an enzyme – that performs a single specified action.

3. A locus (plural loci) is a stable location on a chromosome where a certain gene or genetic marker can be found.

4. At a genomic region, an allele is one of two or more variations of DNA sequence (a single base or a segment of nucleotides).

5. Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.

6. Karyotype: A karyotype is a individual's entire set of chromosomes. A laboratory-produced representation of a person's chromosomes extracted from an individual cell and arranged in numerical order is also known as a chromosomal map. A karyotype can be used to check for chromosomal number or structural problems.

8. Genotype: An organism's genotype is its genetic makeup. From embryonic development to adulthood, the genotype determines an individual's inherited potentials and limitations. In se×ually reproducing organisms, a person's genotype is made up of the whole set of genes acquired from both parents.

9. Phenotype: Physical traits are described by phenotypes. It encompasses both apparent (such as hair or eye color) and measured characteristics (like height or weight). Characteristics relevant to your development and behavior, such as personality traits, are also referred to as phenotypes.

Which ion most readily leaks across a neuron's membrane, helping to establish the resting potential? Which ion most readily leak

EastWind [94]

Answer:

K+

Explanation:

Leak channels are the gated channels that randomly open and close. The plasma membranes have many more potassium ion (K+) leak channels than the leak channels for other ions such as sodium ion. Also, the potassium ion leak channels are leakier than the sodium leak channels and allow exit of more and more K+ from the neurons. This makes the inside the neuron negative at rest and outside becomes more positive. In this way, the leakage of K+ across the K+ leak channels is mainly responsible for maintaining the resting potential.

I am Lyosha [343]

Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

<h3>What are prokaryotic cells?</h3>

Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.

On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.

Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.

Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.
