Answers
When Earth's shadow covers the moon, it is called a lunar eclipse. This is the last option, as the lunar eclipse occurs when the Earth passes between the sun and the moon.
What is a lunar eclipse?A lunar eclipse occurs when the Earth, moon, and sun are aligned in a straight line with the Earth in the middle. When this happens, the Earth blocks the sun's light from reaching the moon, casting a shadow on the moon's surface. There are three types of lunar eclipses: total, partial, and penumbral. A total lunar eclipse occurs when the entire moon is covered by Earth's shadow, known as the umbra.
Hence, when Earth's shadow covers the moon, it is called a lunar eclipse. This is the last option, as the lunar eclipse occurs when the Earth passes between the sun and the moon.

Answer:
live attenuated vaccine
Explanation:
The correct answer would be a live attenuated vaccine.
Vaccines are made from weakened/inactivated pathogens or their toxins and when they are administered to the body, they stimulate the body's immune system to produce antibodies that tend to persist and tackle any future invasion of the body by the pathogen.
Vaccines can be an inactivated ones if they are made from inactivated pathogens, they can be live attenuated if they are made from a weakened or attenuated version of the pathogen, or toxoid vaccine if they are made from toxins of the pathogen. Other forms of vaccines include mRNA vaccines, conjugate vaccines, and viral vector vaccines.

Answer:
El contenedor que tiene fertilizantes crecerá más.
Explicación:
El contenedor que tiene fertilizantes en dosis óptimas crecerá a un ritmo más alto y producirá más vegetación en comparación con otros contenedores que tienen poco o ningún fertilizante porque los fertilizantes tienen los nutrientes que necesitan las plantas en mayor cantidad para su crecimiento y desarrollo. El fertilizante contiene nitrógeno, fósforo, potasa y algunos otros nutrientes que contribuyen al crecimiento y desarrollo del cuerpo de la planta, por lo que podemos concluir de este experimento que el contenedor con nutrientes crecerá más rápido que otros.

dangerous chemicals from a nearby mine have entered this lake. How do you think these chemicals will affect the fish in the lake?
Answers
Answer:
As a result of daily activities, man has been altering the environment since before recorded history. Increased urbanization, the Industrial Revolution, and an overall larger population base have accelerated the process considerably. While providing numerous societal benefits, modern chemical technology has also brought about a marked increase in the number and variety of chemicals ultimately entering natural surface waters. The last century has witnessed a substantial growth of the chemical industry and it is estimated that there are presently over two million known, chemical compounds in existence, with nearly 250,000 new compounds currently synthesized each year. Of this number, it is estimated that approximately 1,000 new chemicals each year will find their way into the environment as the end result of marketing, use, and disposal.

Black, Orange, and White
Orange
Orange and White
Answers
Answer:
Black, Black and White, Orange, Orange and White
Explanation:
Black, black and white, and orange, orange and white are the available fur color possible in males due to the S gene present on an autosome.
What is autosome and X chromosome?When a gene is found on one of the numbered, or non-gender, chromosomes, it is said to be on an autosome.
Here, the O genes are found on the X chromosome whereas the S genes for white spots are found on an autosome. As a result, the progeny have fur that is black, white, and orange.
As a result, there are three conceivable fur colors: black, black, and white, and orange, orange, and white.
Therefore, S gene is present on autosome, hence black, black, and white, and orange, orange and white are possible fur colors in males.

The survival function that occurs inside of these structures relies on which three items?
A. sunlight, oxygen, soil
B. oxygen, carbon dioxide, water
C. sunlight, carbon dioxide, water
D. water, xylem, soil
Answers
Answer:
This question is incomplete as no structure is portrayed, however, the question can be answered based on general understanding. The answer is
C. sunlight, carbon dioxide, water
Explanation:
The structure being referred to in this question is CHLOROPLAST, which is an organelle in plant cells saddled with the responsibility of making food (sugar) via the process of photosynthesis. In order for the photosynthetic process to occur, three major components or raw materials are needed.
The three items that is relied upon by chloroplast in order to perform its photosynthetic function are sunlight, carbon dioxide (CO2), and water (H2O). The CO2 enters the plant from the atmosphere/air while the H2O is absorbed by the roots of plants. The light is absorbed by certain pigments in the chloroplast called CHLOROPHYLL.

Why is oxygen consumption a good measure of respiration in yeast?
Answers
Answer:
The respiration of a suspension of yeast cells was measured by determining the decrease in pressure of the gas above the cell suspension. The apparatus was arranged so that the gas was confined to a constant volume, 16 cm3 and the entire pressure change was caused by the uptake of oxygen by the cells. The pressure was measured in a monometer, the fluid of which had a density of 1.034 g/cm3. The entire apparatus was immersed in a thermostat at 37. In a 30 minute observation period the fluid in the open side of the manometer dropped 37mm. Neglecting the solubility of oxygen in the yeast suspension, compute the rate oxygen consumption by the cells in mm3 of O2 (STP) per hour

Can water change the land quickly, slowly, or both? Explain.
Answers
Answer: Yes, but slowly
Explanation: Flowing water causes sediment to move. Flowing water can erode both rocks and soil.
Materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesn't matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesn't it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition. Faster-moving water has more kinetic energy. Therefore, it can carry larger particles. It can also carry more particles. What causes water to move faster? The steeper the slope, the faster the water flows. It's just like a toy car rolling down a ramp. It will roll the fastest when the ramp is steep. It will roll slower when the ramp is less steep. If the ramp is flat, it may have no motion. The slope of the land causes water to move faster. If a stream or a river is flowing down a mountain, it will move more quickly. If it is flowing across a flat area, it will move slowly. Some minerals dissolve in water. The minerals are then carried along in the solution. Small particles, such as clay and silt, are carried in suspension. They are mixed throughout the water. These particles are not dissolved in the water. Somewhat bigger particles bounce along the bottom. Particles, such as sand, move in little jumps near the stream bottom. They are nudged along by moving water. The biggest particles move in a different way. They are too big to hop. Instead, they roll along the bottom. Gravel and pebbles move in this way. These particles roll or drag along the bottom of the water.
