Menciona tres hechos importantes sobre Charles Darwin y sus viajes
Charles Darwin fue un naturalista inglés que publicó una de las obras científicas más influyentes en el mundo de la biología: “El origen de las especies”. En ella, asentó las bases de la evolución, un proceso que es posible gracias a lo que bautizó como selección natural.
Darwin tuvo ocasión de demostrar sus conocimientos geológicos al mes siguiente, cuando el Beagle alcanzó la costa argentina de Punta Alta. Allí, en un pequeño terraplén de unos seis metros de altura, desenterró fósiles de mamíferos extintos. Entre ellos, restos de perezosos y armadillos gigantes.

The statement which is true about the Krebs (citric acid) cycle and the Calvin cycle (light-independent) is: they both are carried out by enzymes located within an organelle matrix.
The Calvin cycle is a series of chemical events that converts carbon dioxide and hydrogen-carrier molecules into glucose. It is also referred to as the photosynthetic carbon reduction (PCR) cycle of photosynthesis, the dark reactions, the light-independent reactions, or the biosynthetic phase. Plants' stroma, the fluid-filled region of a chloroplast not shielded by thylakoid membranes, is where these processes take occur. These processes involve additional chemical steps that are applied to the byproducts of light-dependent reactions (ATP and NADPH). The Calvin cycle is present in all photosynthetic eukaryotes as well as a sizable number of photosynthetic bacteria.
The complete question is:

Explanation:
Where is most ATP produced in mitochondria?
Most ATP is produced in the mitochondrial matrix, which is the fluid-filled space inside the inner membrane of the mitochondria.
The process of ATP production in the mitochondria is called cellular respiration. It starts with the breakdown of glucose and other molecules in the cytoplasm by the process of glycolysis, which generates a small amount of ATP. The majority of the ATP is generated in the Mitochondria during the process of oxidative phosphorylation, where the electrons from the breakdown of glucose are passed through a series of protein complexes in the inner mitochondrial membrane, which generates a proton gradient that drives the production of ATP via ATP synthase.

What are two variations of fur color in cats?
There are two basic colors of cats, black and red. These are called “dominant” colors. The color of all cats relates to these two colors in some way, by changing the color or covering it up. There is also a “dilute” of each color.
Generally, the colours, which can be termed differently depending on the breed, are: white, red, blue, black, cream, cinnamon, fawn and brown. The colour of a cat depends completely on genetics. The two primary colours in cats are black and red. There are six varieties of cat fur patterns. These are Tabby, Solid, Bicolor, Tricolor, Tortoiseshell, and Colorpoint.
A cat displaying a dominant color (black, red, tortie, etc.) must have a parent which displays a dominant color. Two recessive color parents (cream, blue, etc.) cannot produce an offspring of a dominant color (black, red, etc.).

What is Mendel's law ?
The two inheritance laws that Gregor Mendel found in his research with pea plants are known as Mendel's laws. The law of segregation and the law of independent assortment is these laws.
According to the law of segregation, two alleles of a particular gene separate from one another throughout the development of gametes, resulting in only one allele being present in each gamete. This indicates that just one allele from each parent is passed on to the offspring for a particular gene when the gametes combine at fertilization.
The law of independent assortment: This law states that the inheritance of one trait does not affect the inheritance of another trait. In other words, the alleles for different traits are inherited independently of one another.
Together, Mendel's laws of segregation and independent assortment provide a framework for understanding how traits are passed down from one generation to the next, and how genetic diversity is generated within a population.

ADH factors in the equation of energy balance are a person's personal control and do not count as an adverse effect of ephedra.
What connection exists between the amount of ADH and water reabsorption in the tubules?The kidneys are the target organ of ADH as it moves through the bloodstream. The renal tubules become more porous as a result. This implies that more water can exit the kidney tubule for selective reabsorption back into the circulation.
Does aldosterone make you more hypertensive?Your kidneys release (excrete) sodium through your urine as a result of aldosterone. Water retention results from an increase in salt in your bloodstream.

In rabbits, coat color is determined by one gene with at least 4 different alleles. The table shows the phenotypes for pairings of alleles.
2. What is the order of dominance of the 4 alleles?
Answer:
Full color is a dominant allele of C
Chinchilla has to have a recessive allel of c^ch
Himalayan must have a recessive of c^h
Albino has a recessive allele of c
Explanation:
In complete dominance, one allele completely masks the expression of another allele, which is evident in heter0zyg0us individuals. The order of dominance refers to which allele dominates over which. C>>C-ch>>C-h>>c.
------------------------
When genes express complete dominance, it means that the dominant allele completely masks the expression of the recessive allele.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.
When a gene is multiallelic, we can talk about the order of dominance.
This means that one allele hides the expression of another allele, and there is a third allele that can inhibit the first two, and so on.
For a better understanding, let us analyze the rabbits' example.
The gene that codes for coat color has four alleles.
CC-chC-hcAccording to the image, we know that
⇒ Individuals that express full color have the following genotypes
C C, C C-ch, C C-h, C cWe can see that the C allele is present in all these genotypes, which suggests that this is the dominant allele and hides the expression of all the other alleles.
****C dominates over C-ch, C-h, and c alleles. *****.
⇒ Individuals that express chinchilla color have the following genotypes
C-ch C-chC-ch C-hC-ch cAs we can see, the allele C-ch is always present, meaning that it dominates over C-h and over c alleles.
*****C-ch dominates over C-h and c alleles******
⇒ Hymalayan individuals have the following genotypes
C-h C-hC-h cFrom these genotypes we can assume that C-h dominates over c allele.
⇒ Albino genotype is cc, meaning that the allele c is the recessive one.
According to this analysis, we could assume that the order of dominance is as follows,
C >> C-ch >> C-h >> cThe symbol >> means that the firts allele dominates over all the following ones.
C dominates over ⇒ C-ch, C-h, cC-ch dominates over ⇒ C-h, cC-h dominates over ⇒ cc is the recessive allele-----------------------------------

what percentage of chromosomes normally found in the body cells of an organism do gamete cells contain after meiosis?
The gamete cells contain 50% of the chromosomes found in the body cells of an organism after meiosis.
Meiosis is basically a type of cell division which occurs in the sexually reproducing organisms. This division is observed during the formation of gametes and results in the reduction of the chromosomes in the gametes.
The normal body cells in our body diploid in nature. This means that they contain two complete sets of chromosomes, that is, 23 pairs of chromosomes. When a gamete is formed due to meiotic division, only one half of the chromosome complement is passed on from the parent and therefore the germ cell will contain 50% of the chromosomes found in the body cells of an organism after meiosis.

How is natural selection different from genetic engineering?
Genetic engineering uses a process of insertion of genetic material, which does not occur in nature, by a gene gun or other direct gene introduction methods, or by a specially built bacterial truck.
With the aid of sexual and asexual reproduction that occurs naturally, conventional breeding mostly relies on selection. In order to create the desired crops more quickly than through selective breeding, genetic engineering involves directly changing an organism's DNA.
Any form of selection that results from an organism's capacity for environmental adaptation is known as natural selection. Contrarily, artificial selection is selective breeding that is imposed by a third party, typically humans, in an effort to increase the frequency of desirable traits.

Why does the presence of homology support the pattern component of the theory of evolution by natural selection
It lends credibility to the theory that all species descended from a common ancestor. The term "homology" refers to the belief that all living things have a common ancestry.
This is because homology asserts that many individuals have the same embryological origin as specific organ structures. This structure is functional in some, but not in others, indicating that it was handed down from a common ancestor to subsequent generations.
Natural selection, as we know, is an evolutionary process in which certain members of a species had characteristics in their bodies that were advantageous to the environment in which they lived.
These organisms survived and passed these structures on to their descendants. For this reason, we can say that the presence of homology supports the standard component of the theory of evolution by natural selection because it supports the hypothesis that species descend from a common ancestor.
These creatures survived and passed on these structures to their offspring. As a result, the presence of homology supports the standard component of natural selection theory since it supports the premise that species descend from a common ancestor.
