I will choose a frog.The CO2 molecule is produced in aerobic respiration as a product from decarboxylation(R-COOH--->CO2+R-H) in Kreb's cycle. The CO2 molcule will leave the mitochondria. CO2 from the will diffuse from the muscle cell to the capilaries. From the capilaries the molecule will go into a vein. It will brought to the right atrium by the inferior vena cava. During atrial systole the molecule will be pumped in the ventricle(frogs only have 1 ventricle). During ventricular systole the molecule will be pumped into the pulmonary artery into the lungs where it'll diffuse out of the capilaries into the lungs and will be expired.

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).
Charcot-Marie-Tooth is a muscular wasting disease that affects 1 in 2,500 people. Researchers have discovered that this occurs when a large gene on the short arm (p-arm) of chromosome number 17 makes a new copy of itself. What kind of chromosomal mutation is this?
Answer:
Type X Charcot-Marie-Tooth disease (CMTX) is caused by mutations in genes on the X chromosome, one of the two sex chromosomes. Within the various types of Charcot-Marie-Tooth disease, subtypes (such as CMT1A, CMT1B, CMT2A, CMT4A, and CMTX1) indicate different genetic causes.

20. D. The solution has the same solute concentration that the cytoplasm does.
21. C. Concentration gradients
Explanation:
In passive transport substances from a region of high concentration to a region of low concentration without the input of energy. Example : Diffusion, Osmosis. temperature and pressure can affect diffusion
Osmosis is a passive transport process in which what's emotional area of less concentration to an area of higher concentration.
Cells in a hypotonic solution swell as water enters and may burst if the concentration gradient is large enough.

Answer:
technology has helped make the daily lives of people easer. it has also caused lost of problems such as using up all of the fossil fuels. it has also let to pollution and global warming.
Explanation:
Answer:As with technology's influences on culture and society, the effects of a technology on the environment can be either positive or negative. Since the Industrial Revolution and the rapid growth of human populations, the potential for technology to have a major impact on the environment has grown. Consequently, an essential aspect of technology and engineering literacy is an understanding of certain key principles about the effects of technology on the natural environment and of the many important efforts that people have made to preserve natural habitats, reduce air and water pollution, and maintain a healthful environment.
Individuals who are literate in technology and engineering should be aware of methods that have been developed to reduce the environmental impacts of technology. For example, an important step in designing a new product is to take the product's life cycle into account. Such an analysis may start with the raw materials that need to be mined or grown, the industrial processes and energy needed to manufacture the product, the transportation technologies required to get it to market, and its eventual disposal when the product is no longer needed.

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.

Explanation:
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
