Explain why DNA Sequencing proves that all species have a common ancestor
Answer:
Below
Explanation:
The reason why we can conclude that all species have common ancerstory is that all the species have several same base pairs. Here are a few listed:
A-G-G-C
As well as this later on:
C-C-A-A-C-C
Because this strand of DNA has several common base pairs, we can conldude that the species have common ancestory that made it this way.

The _____ of a species is usually the result of predation, competition, and other types of interaction between species.
Answer: Realized Niche
Explanation:
Realized niche is also referred to as Post Competitive niche and can be defined as a thriving environmental area created by a group of organisms to survive from an exsisting Faundermental niche where interactions (predation, competition, light, water,food) with other organisms were limited and competed for.
For example. In a tree( Faundermental niche) which houses different species of birds, In order to survive, each specie of the birds will create a realized niche so as to survive from predation, competition, light etc which the whole tree provides.

Refer to the following information to answer the questions below. A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive. They have a daughter who is a dwarf with normal color vision. What is the probability that she is heterozygous for both genes
Answer:
Considering the whole progeny ⇒ the probability of having a girl heterozygous for both genes is 4/16 = 1/4 Considering only girls ⇒ the probability of having a girl heterozygous for both genes is 4/8 = 1/2Considering only dwarf girls with normal color vision ⇒ the probability of having a girl heterozygous for both genes is 4/4 = 1Explanation:

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and recessive forms of the trait. Label the pedigree with genotypes, using the letter H to represent the dominant allele for the trait and the letter h to represent the recessive allele."
I'm confused on the part about having two generations. How do I set up the pedigree?
Answer and Explanation:
First, you need to know how to interpret a pedigree representation.
Family members→ Individuals are represented with geometrical figures.
→ Males are squares
→ Females are circles
Trait/Phenotype→ Healthy/normal/not affected individuals are represented with empty figures
→ Affected/mutated individuals are represented with solid black figures
Generations→ Each file is represented with a roman number, indicating the Generation.
Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.
Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.
We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.The representation would be like following,
I → First-generation: First cross
Man Hh (1) Woman Hh (2)II → Second-Generation: F1 and second crosses
Man hh (3) x Woman hh (4)Woman hh (5)Man HH (6)Woman Hh (7) x Man HH (8)III → Third-Generation:
A boy (9) and a girl (10) hhA girl (11) HHYou will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.
If you draw another pedigree, remember to include
the figures representing males and females, color and H/h representing the phenotype, Roman numbers representing the generations, and optional, numbers naming each member.

Explanation:
A __________ is an example of a signal molecule that can bind to an intracellular receptor and thereby cause a gene to be turned on or off. a protein b glyceride c nucleic acid d steroid e carbohydrate
Answer:
D. steroid
Explanation:
Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.
However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.
¿Cómo defines a una Célula Haploide?
Answer:
La mitad de cromosomas.
Explicación:
Las células haploides se refieren a aquellas células que tienen la mitad de cromosomas. Estas células haploides se forman debido a la división celular de la meiosis. En la división celular de la meiosis, una célula madre se divide en cuatro células hijas que tienen la mitad de cromosomas. Estas células haploides están presentes en los espermatozoides de los gametos masculinos y femeninos, que se fusionaron formando células diploides que tienen el doble de cromosomas. El cigoto formado debido a la fusión de espermatozoides y óvulos son de naturaleza diploide.
