Answer
Mice share a common ancestor with humans, homologousExplanation:
The DNA of humans and mice is almost 92% similar. This similarity indicates that mice share a common ancestor with humans. Mice have a tail, while humans have a tailbone. The tailbone is a homologous structure in humans.
The existence of similar genes (DNA) and pair of structures (tail and tail bone) between humans and mice is referred to as homology. The tail and tail bone that exist between the different animals are called homologous structures. Homologous structures are similar structures that can be found in different animals, indicating that the animals have evolved from a common ancestor. Homologous structures show a high degree of similarity in form but they may or may not have the same functions in the different animals.
The similarity in the DNA and the structures (tail and tail bones) that exist in humans and mice suggests that the two different specie are connected to a common ancestor.

What is the role of xylem in a vascular plant?
A. Transports salt to the roots of the plant
B. Transports chloroplasts to the leaves of the plant
C. Transports carbohydrates from the leaves to the roots
D. Transports material from the roots up into the plant
SUBMIT
the correct answer is D
The role of the xylem in a vascular plant is to transport material from the roots up into the plant.
What do you mean by Vascular plants?Vascular plants may be defined as those plants that have a specialized conducting system that includes xylem and phloem.
Xylem is known to transport water and all essential nutrients and minerals from the roots to the leaves.
Phloem on the other hand transport food from the leaves to the roots.
Therefore, the role of the xylem in a vascular plant is to transport material from the roots up into the plant.

Put the following events that occur in a reflex arc in the correct order. Rank the options below. The motor neuron conducts action potentials through the anterior root and spinal nerve to an effector organ The motor neuron conducts action potentials through the anterior root and spinal nerve to an effector organ Open choices for matching The interneuron synapses with a motor neuron The interneuron synapses with a motor neuron Open choices for matching The sensory neuron synapses with an interneuron The sensory neuron synapses with an interneuron Open choices for matching A sensory neuron conducts action potentials through the nerve to the spinal cord A sensory neuron conducts action potentials through the nerve to the spinal cord Open choices for matching A sensory receptor detects a stimulus
Answer: Please see the explanation column for answers
Explanation:
A reflex arc is a nerve or neural pathway that controls a reflex action giving fast response to a stimulus without the conscious act of the brain. Here, the sensory neurons receive stimulation then synapses or connects to spinal motor neurons nerve cells which then connects to muscle cells acting as effectors.
Ranking the events that occur in the reflex arc in correct order gives
1st ---- A sensory receptor detects a stimulus
2nd---A sensory neuron conducts action potentials through the nerve to the spinal cord
3rd----- The sensory neuron synapses with an interneuron
4th----- The interneuron synapses with a motor neuron
5th------- The motor neuron conducts action potentials through the anterior root and spinal nerve to an effector organ.
Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

Plates push away from each other.
Mid-ocean ridges mark locations.
Answer:
its b i took the test
Explanation:
Subduction describes convergent boundaries.
What is convergent boundaries?Lithospheric plate borders that are convergent are those where the plates are moving in the same direction. These regions' plate clashes have the potential to cause earthquakes, volcanic eruptions, and crustal deformation.
The thicker, less dense continental plate pushes aside the thinner, more dense oceanic plate when the two plates contact. Subduction is the process by which the oceanic plate is pressed into the mantle.
The oceanic plate is pushed into regions with increasing temperatures as it falls. Materials in the subducting plate start to approach their melting temperatures and partial melting starts to take place at a depth of around 100 miles (160 km).
Therefore, Subduction describes convergent boundaries.

How would the coils in the middle of the diagram
change to show a longitudinal wave with higher
energy?
They would be farther apart.
They would be closer together.
They would be shaped like a hill.
They would be shaped like a valley.
Answer:
The correct answer is - option C.
Explanation:
A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.
In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.

A female had tubular pregnancy and had to remove her oviducts. Will this affect her in anyway with respect to reproduction ? justify?
Reproduction will be highly affected.
Since there are two oviducts one will be removed as a result of the ectopic pregnancy.
Hence, there will be a defect in the carrying of the ovum from the ovary to the uterus. There will be delivery of the ovum only in the the unaffected oviduct. This can lead to non-fertility.
Ectopic pregnancy is a condition in which there is an implantation of the zygote in a location other than the the uterus.

Answer:
its D
Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
Hence we can conclude that The wax covering an iron rod melts when the rod is heated is not a result of convection current
