Answer: A
Explanation:
Active transport requires energy while diffusion does not
Active transport pumps molecules and ions against a concentration gradient. Thus, option A is correct.
What is the main role of active transport?As contrast to assisted diffusion, which carries molecules or ions along a gradient of concentration without the application of energy. An organism occasionally needs to transfer items up or down a gradient of concentration.
In order for cells to acquire molecules or ions from the environment in opposition to the concentration gradient, active transport is a crucial activity.
Because active transport is not passive and requires molecules to move against a concentration gradient, it requires energy.
On the other hand, metabolic products or electrolytes that are substantially loaded into cells might be expelled in opposition to the concentration gradient.
Therefore, Active transport requires energy while diffusion does not.

Answer:
Find answers below.
Explanation:
The brain is a delicate organ but it is protected by cranium and meninges. The brain is organized into four regions: Hindbrain, Forebrain, Midbrain and Brainstem. The hindbrain and the brainstem includes the brain and spinal cord. The midbrain is the third part of the brain stem, and serves to relay sensory and motor information between the spinal cord and the rest of the brain. The forebrain includes the hypothalamus, the thalamus, the pineal body, and the cerebrum. The cerebrum is divided into four distinct lobes and two hemispheres. Of these, the frontal lobe is responsible for cognitive functions, the parietal lobe is responsible for sensory functions, the temporal lobe is responsible for auditory (language and memory) functions, and the occipital lobe is responsible for visual functions. Distinct from the spinal cord, the brain is serviced by 12 pairs of nerves that include the optic nerve and the nerves responsible for tongue movement and hearing and balance.

Answer:
(a)
Protoplanets are built up through the collisions of planetesimals over millions of years. The protoplanets orbit stably around the Sun for a while, but eventually they collide with each other. In about 100 million years, several terrestrial planets, like the ones found in our Solar System, are formed.

Students have been studying cellular respiration in their biology class and are working on a computer simulation that allows them to test the effects of several variables on the products of respiration. In one simulation, they are asked to change the initial concentrations of several gases, one at a time, to see the impact on ATP production in a muscle cell.
If the students begin by removing oxygen from the muscle cell, what should they predict will occur?
The cell will produce more ATP because oxygen inhibits ATP production in the mitochondria.
The cell will produce no ATP at all since oxygen is critical to ATP production.
The cell will produce the same amount of ATP since oxygen is not a factor in ATP production.
The cell will produce some ATP but in much lower amounts than if oxygen was present.
If oxygen was present is low, then cell will produce some ATP but in much lower amounts. Option D is correct.
Cellular respiration depends on many factors such as,
Glucose concentration: as concentration of glucose drops the rate of ATP production will also reduce.Oxygen concentration: as concentration of Oxygen drops the rate of ATP production will also reduce.Therefore, if oxygen was present is low, then cell will produce some ATP but in much lower amounts.

Saturated fats have a____________ high potential for spoiling when exposed to oxygen or heated and unsaturated fats have a___________ low potential for spoiling when exposed to oxygen or heated due to their chemical structure.
Answer: SATURATED fats have a LOW potential for spoiling when exposed to oxygen or heated and UNSATURATED fats have a HIGH potential for spoiling when exposed to oxygen or heated due to their chemical structure.
Explanation:
Fatty acids are long chain alkanoic acids which contains about 10 to 18 carbon atoms. The terminal -COOH group is polar, hence the acid is able to dissolve in water. The carboxylic acid group ionizes in water to a certain degree to form hydrogen ion and the carboxylate ion. Fatty acids are this weak acids. While the long alkyl group is non-polar, and so is not soluble in water. Fatty acids are divided into two:
--> SATURATED fatty acids: In this type of fatty acid, there are absence of double bonds in their hydrocarbon chain. As a result, they are solid at room temperature. Example of saturated fatty acids are found in animal products which includes: milk, cheese and beef. Saturated fatty acids has a LOW potential for spoiling when exposed to oxygen or heating because of their chemical structure. They are usually formed by hydrogenation of unsaturated fatty acids causing them to attain stability in their chemical structure.
--> UNSATURATED fatty acids: In this type of fatty acid, there are presence of one or more double bonds in their hydrogen chain. As a result, they are usually liquid at room temperature. Examples include: vegetable oil, fish oil and groundnut oil.
UNSATURATED fats have a HIGH potential for spoiling when exposed to oxygen or heated due to their chemical structure. The presence of unstable double bonds in their hydrocarbon chain allows oxygen to react with it easily. To makes it spoil easily when exposed to oxygen.

Using what you learned, choose the queen with the traits that would best help the hives.
Then explain your choice in the box below. This is called a hypothesis.
Answer:
Queen C
Explanation:
queen C because they need a bee with high aggression and normal venom to fight the wasp.
A queen bee is the most important in a bee hive. She lays eggs and can lay over a thousand eggs every single day. Their lifespan is about 5 years.
What are the characteristic traits of a queen bee?A queen bee is the largest in the bee hive and has around 20 mm in size.
Her most significant organ is her female reproductive organ (spermatheca), where the sperm collected during mating flights is stored. This sperm will be used for the rest of its life to fertilize eggs and create female bees. The queen bee plays the most important role in the bee hive and is the only female with fully developed ovaries.
The queen bee's stinger is smoother as compared to the worker bees. The queen uses a stinger while laying eggs and fighting with the other bees.

Question: List the principles you used to determine the age relationships:
Answer:
Crosscutting, Superposition, Original Horizontality
Explanation:
Superposition means that the layer of rocks that was deposited first must be on the bottom unless overturned by some geologic even later on. In this case, that allows us to confirm that D is younger than H because D was deposited on top of H.
Crosscutting is also used, which is where you see your faults. Think logically: for something to cut across a layer of rock, the layer of rock must exist to be cut across. This principle makes letter B younger than letters C, A, and F, but older than H, as B does not cross cut H.
Original Horizontality is also used. This simply means that when a layer of rocks is deposited it is deposited roughly horizontally. This in essence is saying for example, that layer C was originally deposited completely flat, like a brick. Then, letter B came along later and cracked the brick in half, then pushed one half of the brick up, making the brick (layer of rock) uneven.

It is important to note, however, that ECGs record the electrical currents generated by cardiac muscle indirectly : They measure the electrical activity present in body fluids from the cardiac impulse that reaches the body surface. What other aspect of this method should one remember when analyzing ECGs
The aspect of the ECG method orientation of electrodes in the body surface can affect the output in an ECG.
What is a method of ECG?Track down the P wave, and determine how P waves and the QRS complex are related. ECGs record the electrical currents in the body.
Analyzing the QRS morphology in the orientation of electrodes in the body surface can affect the output in an ECG, used to measure impulse in the body.
Which runs down the bottom, divide 300 by the number of big squares found between R waves (if the patient is in atrial fibrillation it is more accurate to report a rate range rather than a single value).
