Animals that eat plants get the energy stored in the plants and use it for things such as moving around. However, only a small fraction of the energy in the plants gets converted to useful energy for the animal. Most of the energy is lost to heat. How can this situation be used to support the idea of the law of conservation of energy?
A. A The amount of energy used by the animals, added to the amount of energy lost to heat, equals the amount of energy from the plants eaten by the animal.
B. B While some animals get their energy from plants, there are also many animals that get energy by eating other animals, and still other animals that eat both.
C. C All the energy lost to heat by animals provides the heat energy that plants need to live and grow, allowing them to make their own food.
D. D When plants and animals die, their energy goes into the soil, where growing plants can absorb it, turn it into food, then transfer this energy to animals.
Answers
Answer:
A. A The amount of energy used by the animals, added to the amount of energy lost to heat, equals the amount of energy from the plants eaten by the animal.
Explanation:
The law of conservation of energy states that "energy can neither be created nor destroyed but can only be changed from one form to another". This means that during the energy transfer cycle, energy cannot be created or destroyed by any process, however, it can only be changed from one form to another via the different processes undergone by living organisms.
This question describes how animals get food needed for their life processes by feeding on plants. However, they (animals) make use of only a little fraction (about 10%) of the total energy in plants they feed on, because most of the energy (about 90%) is lost as heat when the plant undergoes metabolic activities.
This situation describes the law of conservation of energy in the statement that "The amount of energy used by the animals, added to the amount of energy lost to heat, equals the amount of energy from the plants eaten by the animal" because it shows that energy cannot be created neither can it be lost, hence, the sum of the energy that was converted to heat energy by plants and the energy utilized by the animal will give the total amount of energy initially present in the plant before the animal fed on it.

Answers
The organelles carry genetic material from inside the nucleus to the chloroplasts for reproduction.
The correct option is D.
Which cells are organelles?It's also crucial to remember that eukaryotes, being one of the three main cell divisions, are the only ones to have organelles. Prokaryotes, which include the other two major divisions of bacteria and archaea, lack membrane-bound organelles.
What tasks do organelles perform?Like an organ in the body, an organelle is a subatomic structure that performs one or more particular functions for the cell. Some of the more important cell organelles are the nucleus, which stores genetic material, the mitochondria, which provide energy stored, and the golgi apparatus, which assemble proteins.

1)Blood flows from the atria to the ventricles via a pathway from the right segment (deoxygenated blood) to the left side (oxygenated blood) the pathway can be summarised as follows
Right atrium (from venacava)>right ventricle >lungs>left atrium >left ventricle
2) Arteries-narrow lumen,thick elastic walls (high blood pressure)
Veins-wide lumens,thin inelastic walls (low blood pressure)
6) Red blood cells-carry oxygen which combines with heamoglobin in them to form oxyhaemoglobin for respiration
White blood cells-prevents the entry of pathogens and harmful microorganisms either by releasing antibodies or engulfing them (phagocytosis)
9) Pulmonary usually involves the blood pathway and to and from the lungs usually at a lower pressure whilst systemic circulation is the movement of blood to and from body cells at a higher pressure
10) helps to control the internal body temperature via dilation or constriction which can maximise or minimise heat loss depending on the heat change

Please help before Feb 14 (thats when this is due) thank you!
there are 5 lines for me to write so try to stretch it out
Answers
Answer:
When the isotopes decay, scientists can find out how old the rock is depending on the radioactive isotope's half-life.
Explanation:
Radioactive isotopes are unstable and will decay. For example, when humans die carbon-14 decays. The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope. At the next half-life there will be 25% of the radioactive isotope and 75% of the stable isotope. At the next half life there will be 12.5% radioactive and 87.5% stable.
Example:
Carbon-14 is a radioactive isotope with a half life of 5,730 years. How old would carbon-14 be when there is 75% carbon-14 in the rock?
75% is half of the time before the half-life, so it would be 2,365 years.
Hope this helps. Half life helps scientists find how much the isotope has decayed and the age of the rock.

Why do your fingers look like prunes after swimming for a long time?
Answers
Answer:
pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.
Answer:
This is because when you swim in a pool for a while your hand seem to be pruney and it is because when the hand is soaked in water, the nervous system sends a message to the blood vessels in your hand to shrink.
And the reduction of blood from the area in your which is soaked and then your hand seems like pruney
