Answer:
Explanation: This process is called mitosis. However, parental gametes – the sperm and egg cells – are unique from all other cells in that they reproduce through a process called meiosis. The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.tion:

La miopia es un caracter bastante comun en la especie humana. Un matrimonio en el que ambos conyugues poseen vision normal, tienen dos hijos, uni con una vision normal y el otro con miopia. Teniendi en cuenta el fenotipo de todos los miembros de la familia ¿quenpodrias deducir del gen que controla la miopia? ¿ que genotipo podrias asignsr a cada individuo?
Answer:
El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm Tendrían otro hijo homocigota recesivo con miopia, mm.Explanation:
Datos disponibles:
Ambos padres poseen visión normalUno de los hijos tiene visión normalEl otro hijo tiene miopiaPodríamos establecer que M es el alelo dominante, mientras que m es el alelo recesivo.
A partir de la información brindada, podríamos suponer que:
Opción 1:
La miopia es un caracter expresado por un gen dominante. Si este fuera el caso, entonces al menos uno de los padres debería tener miopia para poder heredarle al hijo el alelo dominante para expresar el caracter. Si este fuera el caso, los posibles genotipos de los padres serían:
Parental) Mm x mm (al menos uno de los padres con miopia)
F1) 1/2 Mm (Hijo miope)
1/2 mm (Hijo con visión normal)
Pero en este caso, los dos padres tienen visión normal, entonces si el gen dominante expresa la miopia, los genotipos de los padres serian homocigotas recesivos, mm. Si ambos padres son homocigotas recesivos, no podrían heredarle a ningun hijo el alelo de la miopia. En este caso, la cruza sería:
Parental) mm x mm
F1) 100% mm (todos los hijos con visión normal)
Sin embargo, para el ejemplo planteado, los dos padres tienen visión normal, uno de los hijos tiene visión normal y el otro tiene miopia, lo que nos conduce a la segunda opción.
Opción 2:
La miopia es un caracter heredado por un gen recesivo, m. Mientras que la visión normal es heredada por un gen dominante, M. Entonces, si este fuera el caso, para que ambos padres con visión normal, tengan un hijo homocigota recesivo para el caracter, entonces ambos padres deberian ser heterocigotos. Su hijo miope heredaría un alelo recesivo de cada padre y expresaría el defecto. El genotipo de las personas con miopía sería entonces homocigota recesivo. Esta cruza sería de la siguiente manera:
Parental) Mm x Mm (Ambos padres heterocigotas)
Gametos) M m M m
Cuadro de Punnet)
M m
M MM Mm
m Mm mm
F1) 3/4 o 75% de probabilidad de tener un hijo con visión normal
1/4 o 25% de probabilidades de tener un hijo miope.
Entonces, podemos concluir que:
El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm Tendrían otro hijo homocigota recesivo con miopia, mm.plzzzz hellppppp due today

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched
The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

How does cellular respiration demonstrate
the conservation of mass?
Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:
C6H1206 + 6O2 ---- 6CO2 + 6H2O
Th number of atoms of reactants equals the number of atoms of products:
six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms
No atoms are created or destroyed in this process, they're just rearranged into different molecules.
We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.
Cells use cellular respiration to convert glucose into energy for cellular function. A chemical process that, when balanced, complies with the Law of Conservation of Matter might serve as a metaphor for it:
6CO2 + 6H2O = C6H1206 + 6O2
What is cellular respiration?
Cellular respiration converts glucose into ATP, which powers various physiological functions. Cellular respiration involves glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glucose fuels cellular respiration. A balanced chemical reaction represents it:
6CO2 + 6H2O = C6H1206 + 6O2
Reactants and products have equivalent atom counts.
This technique rearranges atoms into molecules without creating or destroying them. Living creatures "burn" glucose for energy. Burning conserves matter. Because CO2 and water are gaseous, colourless, and invisible, it may seem that the burnt material is totally consumed. Antoine Lavoisier was the first to demonstrate mass conservation in chemical reactions by conducting combustion processes in a closed system and catching the gaseous products.

If a DNA strand has 23 % guanine before semi conservative replication occurs, what percent Thymine will each new strand have after replication?
Answer:
27%
Explanation:
DNA is a linear molecule composed of four nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Chargaff's rules state that adenine (A) always pairs with thymine (T), while guanine (G) always pairs with cytosine(C). In consequence, the amount of G should be equal to the content of C, while the amount of T should be equal to the content of A. In this case, the content of G is 23% and the content of C is also 23%, so the remaining content (A + T) is equal to 54% [100 - (23 + 23) = 54%], thereby content of A is equal to 27% and the content of T is also 27% (27 + 27 = 54%).

Answer:
fertilizer creating a mutation among a farmer's crops
Explanation:
A genetic factor is one that affects the gene or genome of an individual organism. This genetic factor often influences the observable trait called PHENOTYPE of the organism. In this case, an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor is the "fertilizer creating a mutation among a farmer's crops"
The fertilizer represents the environmental/chemical factor which is creating the genetic factor (mutation) that will eventually influence the growth or development of the crops.
