Of all of the offspring have short hair and around half have black claws, what is the most probable genotype of the father
Answer:
The father most likely has HH and cc as its genotypes.

WHAT IS PHOTOSYNTHESIS ??
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
What's photosynthesis?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. It appears that only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Answer the following questions regarding the few survivors that now begin to rebuild the human population.
Certain traits will have been lost from the gene pool forever. Some may be obvious, like people with red hair and double jointed thumbs. Others will be less obvious, like the ability to process cholesterol or being allergic to peanuts.
a.) Which of the following best describes the mechanism of microevolution that has altered the human gene pool? Explain.
b.) Despite an abundance of habitat, why will it be difficult for the human species to recover in numbers?
c.) A straggler with green eyes stumbles into the last remaining human outpost. The green eye trait did not exist in the outpost before her arrival, but it does now. What is the name of this mechanism of evolution? Explain.
Answer and Explanation:
A. Hello. You did not enter answer options. However, we can state that mutation, natural selection and genetic drift will be the microevolution mechanisms that will affect the gene pool of these humans. This is because the new environment and the small number of living beings, will make this population completely susceptible to all these evolutionary factors, which will affect, in different ways, the gene frequencies in a population.
B. As the amount of living beings and human beings has become very small, the world will have a low genetic diversity. This will make it difficult for these humans to adapt to the new environment and will make them more susceptible to possible diseases that will arise in this new environment. This will make these humans more fragile and make it harder for them to multiply.
C. The evolution mechanism is the Gene Flow. Gene Flow refers to the exchange of genetic information between individuals in a population, through the donation of gametes that occur in reproductive processes. In this case, we can consider that the individual with green eyes, upon arriving in the community with individuals without green eyes, began to reproduce descendants, who, upon receiving the gametes responsible for green eyes, began to populate this community with this characteristic.
2) ¿Cuál de los siguientes hechos no es una evidencia de una reacción química? a) Presencia de un catalizador b) Cambio de color d) Liberación de gas
Answer:
a) Presencia de un catalizador
Explanation:
Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.
Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.
Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.
La evidencia de que ha tenido lugar un cambio químico incluye
1) La formación de un precipitado a partir de la mezcla de sustancias.
2) Un cambio en el color de las sustancias.
3) Un cambio en el olfato (que desprende un olor) o en el sabor.
4) La sustancia produce luz (brilla)
5) El volumen total cambia
6) Cambio de temperatura (la mezcla se calienta o enfría)
Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.

Una especie de mariposa presenta rasgos fenotípicos diferentes entre los miembros de sus poblaciones. Estos rasgos van desde una coloración verdosa y antenas cortas (características recesivas). El fenotipo más común (características dominantes) de esta especie es de coloración amarilla y de antenas tan largas que se pueden doblar. Realice el cruce entre dos mariposas que presentan fenotipo más común, pero de genotipos heterocigotos y determine los posibles rasgos fenotípicos que se pueden presentar.

How do animals and people cause weathering?
How do plants cause weathering ?
Answer:
Plants can cause mechanical and chemical weathering
Explanation:
Plants can cause mechanical and chemical weathering. When plants cause mechanical weathering, their roots grow into rocks and crack them.It can also happen in streets or sidewalks. When plants cause chemical weathering, there roots release acid or other chemicals, onto rocks, which then forms cracks, and breaks apart.
Animal and plant mobility is a factor in biological weathering, for instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand.
What is the cause of weathering?A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock.
Animals and plants can act as mechanical weathering agents. In dirt that has gathered in fractured rock, a tree seed may emerge. The fissures get wider as the roots spread out, finally shattering the rock into pieces.
Even big rocks might get dislodged by trees over time, rocks are broken down by plants like moss that absorb their minerals.
Therefore, holding onto soil and rocks is another way that plant roots cause weathering, and might stop erosion.

Mateo and Tomás are identical twins. Mateo was raised by his father and mother, and Tomás was
accidentally placed with another family after a mix-up at the hospital. At the age of 15, the boys ran into
each other at a football game and noticed that they appeared to be mirror images of each other. After
genetic testing proved that they are twins, the families discussed some of the differences between the boys.
Mateo is very athletic and intelligent and excels in basketball, but he does not take school seriously and has
F's in all subjects. Tomás is also athletic and intelligent and excels in baseball, and he makes straight A's as
a result of his strict home life and study routine. Although they are identical twins, what do you think
accounts for the differences in the two boys' academic performance based on the research?

An injury to the spinal cord in which section of vertebrae could cause tetraplegia?
Answer:
The nerves exiting the vertebrae in the neck area or cervical segments are referred to as C1 through C8. These nerve control signals to the neck, arms, hands, and internal organs. Injuries to these areas result in tetraplegia.
Answer:
cervical
Explanation:
“Most people with tetraplegia have significant paralysis below the neck, and many are completely unable to move. This form of paralysis is typically the product of damage high in the spinal cord, usually in the cervical spine between C1-C7. The higher the injury is, the more extensive the damage will be.”
