Explain why oxygen molecules can pass directly through the cell membrane.
Answer:
Oxygen molecules are small and nonpolar, which allows them to easily pass through the cell membrane.
Answer: It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood. It too is small and uncharged so it can pass through cell membranes easily.

Carbon is one of the elements that are involved in the biogeochemical cycle.
One way carbon moves from the atmosphere to the biosphere is through a process by which plants use light energy and convert it into biochemical energy. This process is called photosynthesis. Plants use energy from the sun to combine carbon dioxide and water to form glucose.
In photosynthesis, six molecules of carbon dioxide react with six molecules of water to produce oxygen and glucose as follows;
6CO2 + 6H2O ---->C6H12O6 + 6O2. The products of photosynthesis are glucose and oxygen.
Carbon is incorporated into the carbon cycle via water in the hydrosphere when carbon dioxide dissolves into oceans as the bicarbonate ion. The oceans serve as the largest reservoir of carbon. About 37,000 billion tons of carbon are stored in the oceans out of about 65,500 billion tons of carbon available globally.
Proteins, nucleic acids, lipids, and carbohydrates are based on carbon. Carbon is contained in all biological molecules which makes it very important in biochemistry.
Photosynthesis is a chemical reaction as shown above. It occurs in the chloroplasts of plant cells which is able to trap energy from the sun in order for the process of photosynthesis to take place.
The reservoirs that make up the carbon cycle are four;
hydrospherelithosphereatmospherebiosphereCarbon is transferred from the atmosphere to the biosphere by photosynthesis when green plants absorb carbon in order to produce biomass. The overall scale of the carbon cycle is planetary.

female chickens (hens) that lay larger eggs are chosen to breed with roosters (male chickens)
is it natural selection, artificial selection, or both ?
Answer:
Artificial Selection
Explanation:
Seeing as how it was chosen for them to breed it would not be natural
When the hens that should be lay larger eggs that are selected to breed with roosters should be considered as the artificial selection.
What is artificial selection?It is the selection where the identification should be done by humans with respect to the desirable traits in terms of the plants and animals.Also, the steps should be taken for enhancing the traits in the future generations.
So based on this, we can conclude that When the hens that should be lay larger eggs that are selected to breed with roosters should be considered as the artificial selection.

Earth’s layers are determined by their physical properties and chemical composition. In the lesson, you learned about each of Earth’s layers, what the layers are made of, and why they are important to the Earth. In the space below, write about how the atmosphere may be classified. Would it be part of the lithosphere, or a separate layer? Explain your answer.
Answer:
Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps
Explanation:
Un criador tiene dos tipos de conejos: conejos de pelo corto y conejos de pelo largo. Obtiene los siguientes cruces: a) conejos de pelo corto x conejos de pelo corto → 45 de pelo corto y 14 de pelo largo, b) conejos de pelo largo x conejos de pelo largo → 60 de pelo largo, c). Conejos de pelo corto x conejos de pelo largo → 29 de pelo corto y 31 de pelo largo. I. ¿Cuál es el alelo dominante? II. Escribe los fenotipos y genotipos de cada cruce
Answer:
El alelo dominante es el que codifica para el rasgo pelo corto
Alelo pelo corto (dominante) >> L
Alelo pelo largo (recesivo) >> l
Genotipos parentales y frecuencias esperadas en cada cruzamiento:
a) Parentales: Ll x Ll. Fenotipo progenie: 3:1 (dominante : recesivo); Genotipos progenie: 1:2:1 (1 LL dominante; 2 Ll heterocigotos; 1 ll recesivo)
b) Parentales: ll x ll. Fenotipo progenie: 100% recesivo; Genotipo progenie: ll (100% recesivo)
c) Parentales: Ll x ll. Fenotipo progenie: 1:1 (dominante : recesivo); Genotipo progenie: 1:1 (1 Ll; 1 ll)
Explanation:
En este caso, las frecuencias observadas en cada cruzamiento evidencian que el alelo pelo corto es dominante, ya que en los casos donde la progenie es heterocigota este alelo enmascara la expresión del alelo pelo de pelo corto. Por otra parte, las frecuencias fenotípicas observadas se ajustan a los valores esperados para el caso de dominancia completa, es decir, una proporción fenotípica 3:1 (3 individuos expresando el rasgo dominante por cada recesivo) es característica cuando se realiza un cruzamiento entre dos heterocigotas para un rasgo con dominancia completa (ítem 1). En segundo término, una frecuencia de 1:1 es coincidente con el cruzamiento entre un individuo heterocigota y un homocigota recesivo (ítem c). Finalmente, el rasgo recesivo será expresado en el 100 % de los casos sólo si este carácter es homocigota para ambos parentales (ítem b).
