What causes the equinox to occur twice a year?
Answer:
tilt and orbit of the Earth combine in a way that the axis is inclined away from the sun

We have an equinox twice a year. The Spring and Fall equinox. An equinox occurs when the tilt of the Earth's axis and Earth's orbit around the sun combine in such a way that the axis is inclined away from the sun.
Most fossilized bones have undergone the process of
A)unaltered preservation
B)carbonization
C)casting
D)perimineralization
Answer:
D. Perimineralization
Explanation:
After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.

Match the following terms describing electrical events with the correct phases of the cardiac cycle.
Question Selected Match
The ventricular muscle cells depolarize at the start of this phase.
During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold.
The ventricular muscle cells repolarize right before this phase.
The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase.
All Answer Choices
A. isovolumetric contraction
B. ventricular ejection
C. ventricular filling
D. isovolumetric relaxation
Answer:
1. Isovolumetric contraction.
2. Ventricular filling.
3. Isovolumetric relaxation.
4. Ventricular ejection.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The following terms describe the electrical events with the correct phases of the cardiac cycle in mammals (human beings);
1. Isovolumetric contraction: The ventricular muscle cells depolarize at the start of this phase. During this phase, the pressure in the atria is lower than the pressure in the ventricles while the pressure in the arteries is higher than the pressure in the ventricles.
2. Ventricular filling: During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold. It causes the atria to contract at the end of the phase.
3. Isovolumetric relaxation: The ventricular muscle cells repolarize right before this phase. During this phase, all of the four (4) cardiac valves are closed while all of the four (4) chambers are relaxed.
4. Ventricular ejection: The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. Also, the atrioventricular (AV) valves are closed while the semilunar valves are open.
Consider the following food chain: Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes. In the short term, what will happen to the other members of the food chain if the mice were removed?
a.
the number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease
b.
the number of plants will decrease, the number of grasshoppers will decrease, the number of snakes will decrease
c.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will decrease
d.
the number of plants will increase, the number of grasshoppers will increase, the number of snakes will increase
Answer:
The answer is A
Explanation:
The number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease.
What is Food chain?Everything that is alive, from microscopic algae to enormous blue whales, depends on food to thrive. Each food web represents a possible route for nutrients and energy to travel through the ecosystem.
As an illustration, grass makes its own sustenance from sunshine. A bunny consumes some grass. Eaten by a fox, the rabbit. When a fox dies, microbes decompose its remains and return it to the soil, where it feeds grass-like plants.
Grass is consumed by a wide variety of animals, and rabbits can also consume other plants besides grass. Foxes can consume a wide variety of animals and plants. These living organisms can all be found in different food chains.
Therefore, The number of plants will decrease, the number of grasshoppers will increase, the number of snakes will decrease.

The brain signals the body of an animal to move by transmitting electrical impulses through the neurons. An animal
is then able to walk or run because
F: the glands of the endocrine system work with the skin if the integumentary system.
G: the heart of the circulatory system works with the stomach of the digestive system.
H: the kidneys if the excretory system work with white blood cells of the immune system.
J: the muscles of the muscular system work with the bones of the skeletal system.
Answer:
J
Explanation:
The musculoskeletal system is what enables movement.
The brain signals the body of an animal to move by transmitting electrical impulses through the neurons, and the animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system that is present in option J.
What is the function of the neuron in muscle activity?The neuron stimulates the muscle for the movement because the muscle has receptors for the neurotransmitters, such as at the neuromuscular junction, and the neurotransmitters either stimulate or repress the function, depending on the type of neurotransmitter.
Hence, the brain signals the body of an animal to move by transmitting electrical impulses through the neurons, and the animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system that is present in option J.

In base pairing for the translation of DNA to mRNA, which nitrogen base complements Adenine?
Answer:
Adenine and thymine form base pairs that are held together by two bonds, while cytosine and guanine form base pairs that are held together by three bonds. Bases that bond together are known as complementary. During transcription, DNA is converted to messenger RNA (mRNA) by an enzyme called RNA polymerase.

QVII) Give reason for the following:
1. Light travels in a straight line
Shadows are evidence of light travelling in straight lines. An object blocks light so that it can't reach the surface where we see the shadow. Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.
Explanation:
Since the wavelength of light is very small as compared with the size of ordinary object and diffraction of light is not easily noticed and hence the light appears to travel in a straight line.

The difference between an open and a closed circulatory system is...
Answer:
In the closed circulatory system, blood is confined to a heart and blood vessels, whereas in an open system, hemolymph (blood) moves from a heart through vessels into interconnected spaces called a "hemocoel."
Explanation:
An open circulation the blood is not blood vessels, it instead is pumped into a cavity called Hemocoel.
A closed circulatory system, the blood is pumped through vessels SEPARATE from the interstitial fluid of the body.
