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.

Answer:
17. A. from an area of high concentration to an area of low concentration.
18. A. ATP/energy is required
19. Passive transport
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.
Do bacteria have internal membranes?
Answer: yes
Explanation: Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. ... Some bacteria have a capsule outside the cell wall. Other structures are present in some prokaryotic species, but not in others.
how does h2o and co2 get transported into the chloroplast?
Answer:
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. ... In these reactions, the energy from ATP and NADPH is used to fix carbon dioxide (CO2).Explanation:
hope this helps youMark my answer as brainalistEarth’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

Answer:
The increase in drought is caused by many factors: shortfalls in precipitation; earlier snow melt; a shift away from light and moderate rains towards short, heavy precipitation events; and increased evaporation from soil and vegetation due to higher atmospheric temperatures, all of which have been driven at least .
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).

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.

What are the base pairs for RNA?
Answer:
[tex]{\boxed {\sf Adenine \ with \ Uracil}}[/tex]
[tex]\boxed {\sf Cytosine \ with \ Guanine }}[/tex]

What is the major component of cell membranes
all cell membranes are made of lipids
the major component of the cell membranes is phospholipids which are composed of glycerol that has a phosphate group attached to it and rests of fatty acids
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:
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.

What is pseudosciences?Pseudosciences is the field of sciences that contains assertions that do not allow the possibility of it being logical and can be proved wrong or false by experiments and observations. The conclusions of the pseudosciences lack empirical evidence.
They include the explanation and assertions by the facts and science but do not includes the essentials of the scientific and research methods. They may contain a flawed experimental design due to faulty data. They are based on belief and lack the research methodology.
