It has the ability to eliminate weak animals from a prey population, reducing competition for natural resources.

An ecosystem (or ecological system) is made up of all the organisms that interact with their physical environment.  These biotic and abiotic elements are linked by nutrient cycles and energy flows.

Photosynthesis introduces energy into the system, which is then incorporated into plant tissue. Animals play an important role in the movement of matter and energy through the system by feeding on plants and on one another. They also have an impact on the amount of plant and microbial biomass present.

Decomposers release carbon back into the atmosphere while also facilitating nutrient cycling by converting nutrients stored in dead biomass back to a form that plants and microbes can use.

Explanation:

Answer:

See the answer below

Explanation:

The modern model of the atom sees it as a small structure with a dense, positively charged core called nucleus. The nucleus houses most of the masses of the atom and consists of the proton and the neutron. The positively charged proton is primarily responsible for the positiveness of the nucleus. At some distance away from the nucleus is a light, negatively charged particle called the electron that revolves around the nucleus in an orbit-like fashion .  

For a neutral atom, the number of the positively charged proton balances that of the negatively charged electron which circulate rounds the nucleus. Atoms in which these two particles do not balance each other are no longer described as being neutral.

Answer:

D. Rift Valleys

Explanation:

A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.

Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.

A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision. This action often causes mountain range such as the Himalayas to form by the collision between the plate carrying Eurasia and that of India; as a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.

Hence, Rift Valleys cannot form when two plates collide because they are formed only when the tectonic plates of earth rift or move apart. Also, Rift Valleys are found at the bottom of oceans and on land.

The result of photosynthesis as glucose and oxygen is basically products. The correct option is B.

Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.

Photosynthesis is important because it is the process by which plants convert carbon dioxide into oxygen using sunlight.

Animals require oxygen to survive, and plants serve as nature's air filter, filtering out harmful carbon dioxide.

Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.

Water is metabolized within the plant tissues, which means it ends up losing electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.

Thus, the correct option is B.

The bar graph that is essential to answer the question is attached with the answer:

Answer:

The correct answer is given as follows:

Explanation:

Mean is the average in a common or informal way. It can be calculated by Adding the total numbers up and divide them by the total number of values in the set.

In this case: 37 is the mean value that can be calculated by:

adding all the values: 36.7+36.8+36.9+37+37.1+37.2+37.3 = 259

Number of sets = 7

then mean = 259/7

= 37

Thus, the mean can be calculated by total value divided by the number of sets

The extracellular recording decreased or became smaller when the battery was placed between the voltmeter electrodes. This is because the battery introduced a potential difference that affected the electrical activity being recorded.


1. When the battery is placed between the voltmeter electrodes, it creates a closed circuit.
2. The battery has a specific potential difference or voltage, which can interfere with the electrical signals being recorded.
3. This interference causes a change in the extracellular recording, leading to a decrease in the recorded activity.

When the battery is inserted between the voltmeter electrodes, it completes a circuit and introduces a potential difference into the system. This potential difference affects the electrical activity being recorded in the extracellular space.

Normally, the extracellular recording measures the electrical signals from cells or tissues, such as action potentials or synaptic activity. These electrical signals are typically small in magnitude and require sensitive equipment like a voltmeter to detect.

However, when a battery is placed between the voltmeter electrodes, it adds an additional voltage to the system. This added voltage interferes with the electrical signals being recorded, causing a change in the extracellular recording. Depending on the magnitude and polarity of the battery's voltage, the extracellular recording may either decrease or increase. In this case, it decreased.

This interference occurs because the battery's potential difference affects the electrical potential across the extracellular space. This alters the resting membrane potential of the cells and modifies the way electrical signals propagate through the tissue.

As a result, the extracellular recording is no longer an accurate representation of the original electrical activity. To obtain accurate recordings, it is important to remove any external sources of electrical interference, such as batteries or other devices that can introduce a potential difference into the system.

The statement given "defective α-receptors on his arterioles causing him to be less responsive to norepinephrine." is true because If an individual has defective α-receptors on their arterioles, it means that these receptors are not functioning properly.

The α-receptors are responsible for mediating the response to norepinephrine, a neurotransmitter and hormone that plays a key role in regulating blood pressure and vascular tone. When α-receptors are defective or less responsive, the individual may experience reduced vasoconstriction and decreased sensitivity to norepinephrine's effects. This can lead to difficulties in maintaining normal blood pressure and cardiovascular function. Therefore, the individual would be less responsive to norepinephrine due to the defective α-receptors.
