Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body? Will mark brainiest please explain or I will flag. :)
THANKS
Answer:
Explanation:
Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
what is responsible for pumping blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.

What’s the answer to this question
Answer:
D
Explanation:
Crayfish depend upon small invertebrates for survival. If there is a large decrease in the number of small invertebrates, then there aren't enough nutrients to go around, and so crayfish that don't get nutrients will start dying out.

2.2 A learner gives you a rather expensive cycad in a pot for your birthday. The class monitored and documented its growth throughout Term 3. You decided to leave it outside your classroom during the school holidays but found it dead when you returned to school. Explain to your class why this might have happened. (5)
Cycads are an group of vascular plants that are ancient and were prominent components of the world's flora. As the cycad should not be kept dry, leaving it outside the classroom during holiday and not watering properly was the main reason behind the loss of that cycad.
What are the conditions in which a cycad can grow well?Cycads usually prefer warm, moist environments in full sun for survival. As some species are also adapted to dry arid areas, with less winter rainfall.
With respect to the soil, Cycads can tolerate most garden soils with the addition of compost and organic matter, till they are well-watered.
As the cycad was left in the classroom during the school holidays and was not watered and given compost properly, it was found dead.
Thus, watering and composting was the main reason behind the loss of that expensive cycad.

Explain the process of cell determination
Answer:
role in embryonic growth
depends on a process called cell determination, in which initially identical cells become committed to different pathways of development. A fundamental part of cell determination is the ability of cells to detect different chemicals within different regions of the embryo.
The process in which a previously undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation. Cell determination is influenced by the action of the extracellular environment and the contents of the cell's genome.

identify the different forms that water takes as altitude increases. (surface to the upper troposphere)
At sea level water occur in natural liquid form in seas, lakes, rivers, waterfall. Water can be salty or freshwater.
What is troposphere?The layer of the atmosphere closest to the earth is the troposphere. This layer is where weather occurs. It starts at the surface of the earth and extends out to about 4- 12 miles. The temperature of the troposphere decreases with height. This layer is known as the lower atmosphere.
As the altitude increases water changes its form as on the mountains where temperature is very low, exist in snow form. As the more height increases, the water changes into water vapour. In stratosphere water changes into gaseous form called as clouds.

how can the process melting and cooling of magma affect the rock cycle
Answer:
Lava eruptions can be “fire fountains” of liquid rock or thick, slow-moving rivers of molten material. Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called tephra.
