Use your knowledge of relationships in a food chain, describe how a cow gets the energy it needs to survive YOU MUST USE THE WORDS sunlight, photosynthesis, producer and consumer in your answer
Answer:
All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy. This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.
A water strider sits on the surface of a pond. This occurs because
Answer:

Explanation:
The water strider is one of the most common aquatic insects. Water striders can sit on the water surface due to they have specialized hydrophobic water-repelling hairs in their legs that allow them to use the surface tension of water in order to distribute the weight. Thus, the hairs in the legs of these insects enable them to float and move on the water surface.

Explanation:
Hope it helped
Answer:
A channel protein
Explanation:
A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly. Water channel proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane.

Which two processes allow water to enter the atmosphere?
evaporation and transpiration
precipitation and condensation
condensation and evaporation
transpiration and precipitation
Answer:
its c) condensation and evaporation
Explanation:
Evaporation and transpiration are the two processes that allow water to enter the atmosphere. The correct option is A.
What is transpiration?Transpiration is the method by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and water from the stem and roots moves upwards or is started to pull into the leaves.
The direct impact of transpiration is that it regulates plant temperature and provides water for photosynthesis. It also transports nutrients and sugars through the plant's vascular tissues.
Evaporation is a way of vaporization that occurs on the surface of a liquid as it transitions from the liquid phase to the gas phase.
Both of these process aids to enter water into the atmosphere.
Thus, the correct option is A.

what keeps earth from flying outward into space from its present position
Answer:
Gravitational pull and the earth on its axis
Explanation:
Hope this helps
Gravitational pull and the earth on its axis keeps earth from flying outward into space from its present position.
what is Gravitational force ?A gravitational force is defined as an attractive force which is exerted by a massive body on the massive body. So our body always tries to pull other body towards itself due to this gravitational force.
gravitational force is a force exerted by earth on other objects and can be represented as F=mg
F is the force of gravity, G is the gravitational constant of the universe and it is always the same number, M is the mass of one object, m is the mass of the other object (measured in kilograms, kg), r can be the distance those objects are apart (measured in meters, m)
This force can also be called as Newton's Universal Law of Gravitation And the object that are really far apart from each other don't pull on each other noticeably either.

The element phosporus is located to the right of the element magnesium along the same period in the periodic table.
Which best describes the relationship of the elements ?
A. Magnesium has a larger atomic number
Answer: B. Phosphorus has a larger atomic mass.
C. Magnesium is in the same category as phosphorus
D. Phosphorus has similar chemical properties as magnesium
Answer:
b
Explanation:
The relationship which describes the best of the element"B. Phosphorus has a larger atomic mass."The correct option is B.
Atomic mass:
Atomic mass refers to the combined mass of protons, neutrons, and electrons in an atom.
The periodic table arranges elements in order of increasing atomic number, which corresponds to the number of protons in an atom's nucleus.
Elements in the same period (horizontal row) have the same number of electron shells, while elements in the same group or column have similar chemical properties.Phosphorus is located to the right of magnesium along the same period, indicating that it has a larger atomic number (more protons) than magnesium.Phosphorus has a larger atomic mass, while magnesium has a smaller atomic mass compared to phosphorus.Therefore, the correct option is B.
