Answer:
180m! :D
Explanation:
If the speed of sound is 343m/s
The prey is at a distance d than it would take 2d for sound to get back to bat and time is 1s then
Speed=distance/time
340=2d/1
340=2d
180=d
Hope this is right lol
why shouldn't a microscope get wet
Answer:
A hole in the center of the stage allows light to pass from the light source beneath the stage through the slide specimen, which should be centered over the hole in the stage. Keep the stage dry at all times. Fluids can damage metal parts and also make it difficult to move a slide around on the stage.

Cual seria el recorrido de una molecula de glicosa desde que es absorbida en el intestino delgado hasta que es metabolizada en el cerebro ?
Answer:
Del intestino delgado ---- torrente sanguíneo --- célula u órgano de almacenamiento.
Explicación:
Después de la absorción de glucosa por el intestino delgado, las moléculas de glucosa se difunden por un gradiente de concentración hacia la sangre capilar dentro de las vellosidades y estas moléculas de glucosa se liberan en el torrente sanguíneo. Cuando las moléculas de glucosa se agregan al torrente sanguíneo, la glucosa puede usarse para la producción de energía o almacenarse en nuestros cuerpos, que puede usarse cuando sea necesario. Si nuestro cuerpo necesita energía esta glucosa es absorbida por las mitocondrias de las células para la producción de energía mientras que por otro lado, si no se requiere energía, estas moléculas de glucosa se almacenan en diferentes órganos en forma de glucógeno.
Which option identifies a question to consider in the following scenario? Frannie is thinking of breeding her seven-year-old cow. What is the rate of prenatal growth in cows? How long will her gestational period be? What nutritional supplements are best for pregnancy? How long has it been since the cow’s last calf?
Answer:
How long has it been since the cow’s last calf?
Explanation:
I just took the test. Its like this because if the Cow does not calf for a few years she is less likely to calf.

Explanation:
In a batch culture, bacterial cultures typically exhibit four different phases of growth. In which phase are the cells rapidly synthesizing proteins, but cell numbers are not changing
Answer:
Lag phase
Explanation:
The lag phase is the first phase of bacteria growth and it is refer to period when bacteria is first introduced to the culture and the time it started increasing. The lag phase is the phase bacteria adapt to growth conditions and start surviving in the environment. It is the time bacteria start growing and cannot divide. In this phase , RNA and enzymes are synthesized.
a key feature of enzymes is that they _____.
a. interact generally within cells
b. are changed by reactions
c. are carbohydrates
d. are not used up in reactions
e. force reactions to occur
Answer:
d. Are not used up in reactions
Explanation:
This is a property of enzymes. They are not used up since they don't participate in reactions. They just help increase the rate at which it occurs
A key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.
What are Enzymes?Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being changed in the overall process. It may be thought that all sorts of cellular reactions or processes are mediated by enzymes.
Most of the enzymes are proteins. They are highly specific in nature. Enzymes also exhibit enormous catalytic power. They do not alter the equilibrium state of biochemical reactions.
Enzymes typically speed up the rate of a chemical reaction by lowering the activation energy of a particular reaction. Thus, it leads to the conversion of reactants into products at a faster rate.
Therefore, a key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.

7. The diagrams show stages in the passage of water through a plant,
The circles are the starting points for arrows to show the direction in which the water moves.
Which circle must have an arrow pointing downwards only?
From the understanding of how water moves through plants, the only circle that can have a downward pointing arrow only is A.
Water moves through a plant in the following direction:
Soil ----> root -----> stem ----> leaves
Once water gets into the root from the soil, a conducting tissue known as xylem conducts the water upward through the stem of the plant branching off into the leaves through the petiole. from the petiole, water is then conducted to the mesophyll cells.
Circle D represents the root, so the arrow must be upward.
Circle C represents the stem, the arrow continues upward towards the leaves
Circle A and B represent the leaf. The movement of water within the leaf might requires that it is from circle A to circle B. Hence, the only circle that must have an arrow pointing downward only can only be A.

Animals that have a complete
tube-like gut with two openings
Answer:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects.
Explanation:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects are the animals that have a complete tube-like gut with two openings. A system having a tube with two openings i.e. mouth and an anus is called tubular system. In this tubular system, the animals eat with one opening and the other opening is used for excretion of waste and nitrogenous materials from the body so that's why most of the animals have two openings.
