a. young geese must see some type of box to imprint correctly.
b. the first two days after hatching are a critical period for imprinting in geese.
c. geese have an instinctive tendency to avoid moving, box-shaped objects.
d. geese must be exposed to their mother more than two days after hatching to imprint on her
Answer:
b. the first two days after hatching are a critical period for imprinting in geese.
Explanation:
If geese don't see a moving object first two days after birth, then they won't imprint on anything, thus first two days are important.

What abiotic aspects of an ecosystem can be affected by the biotic aspects?
The abiotic factors refers to things which are not to able to respire, breathe, move, excrete in a specified place. The living organisms will constitute the biotic factors which able to respire, breathe, move, excrete in a specified place.
What is ecosystem?
An ecosystem is defined as all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controlling the biotic factors of an environment.
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.

Seasonal changes are related to the length of a day and the height of the Sun in the sky. Describe how these two factors change throughout a year, and how this relates to the seasonal changes you observe in your home town.
Answer:
it presents a cause and effect perspective
Explanation:
The axis of the Earth rotates in relation to the Sun as it revolves around it, the height of our Sun as seen above the horizon changes as a result of this.
What are seasonal changes?Our Sun is seen to trace a higher route above the horizon in the summer and a lower path in the winter at any given place on Earth.
Since the Earth is slightly inclined toward the Sun during the summer, we are warmed and experience longer, brighter days.
Based on our location, the Earth is tilted away from the Sun throughout the winter, making the days colder, shorter, and with less sunshine.
Therefore, the tilt of a planet's axis and its orbit around the sun are causes of seasons.

Carla did an experiment by placing a piece of smooth, clear glass and a piece of smooth, black stone under a lamp for twenty minutes. Which prediction will most likely be supported by Carla’s experimental results?
The glass will feel warmer than the stone after twenty minutes.
The stone will feel warmer than the glass after twenty minutes.
The glass will reflect all of the light after twenty minutes.
The stone will reflect all of the light after twenty minutes.
Answer:
The glass will reflect all the light after twenty minutes.
Explanation:
because glass surface is smooth.
The prediction that is most likely to be supported by Carla's experimental results is that the glass will feel warmer than the stone after twenty minutes.
Why is it taking so long?This is because glass will absorb and transfer heat more quickly than stone since it is a far better conductor of heat.
The temperature of the transparent glass will rise even faster as a result of its increased ability to absorb more of the lamp's light.
The black stone, on the other hand, will absorb less light and won't be able to transmit heat as rapidly as the glass, thus after 20 minutes it will be colder.

If your body temperature gets too high you can get a heat stroke which can result in death. When your body temperature is high your likely to get a fever, when you have a fever its harder for your body to fight bacteria and viruses.
Answer:
Hyperthermia is a condition that results in an abnormally high body temperature.
Hyperthermia occurs when your body absorbs or generates more heat than it can release.
Heat fatigue, heat syncope (sudden dizziness after prolonged exposure to the heat), heat cramps, heat exhaustion and heat stroke are commonly known forms of hyperthermia.
Explanation:
It's a life-threatening condition that causes your body temperature to rise above 104 degrees Fahrenheit. It causes problems in your brain and other organs. Heatstroke is especially dangerous if your body temperature rises above 106 degrees Fahrenheit.
