D
Cellular respiration
Answer:
C. Net Primary productivity
Explanation:
In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.
The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R
Where, R = energy lost via respiration.

D. A starch molecule is made of more than one kind of atom.
Please help! I suck at Science!
Answer:
A
Explanation:
because it is known as a large molecule
The starch molecule is known as a good source of energy for an organism because the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.
What is a Starch molecule?A starch molecule may be defined as a type of molecule that significantly consists of a chain of glucose molecules that are bound together in order to construct a bigger molecule, which is called a polysaccharide.
There are two types of polysaccharides present in the molecules of starch. They are as follows:
Amylose: It is a linear chain of glucose. Amylopectin: It is highly a branched chain of glucose.These long chains of glucose store a tremendous amount of energy during the synthesis of the starch molecules. Glucose provides instant energy while the breakdown of bonds in starch molecules takes time. So, the energy is liberated accordingly with a long-lasting effect.
Therefore, the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.

Compare and contrast a few aspects of animal and plant cells. You can focus on intra- and extracellular structures they share or don't share, but also be sure to describe processes they both utilize or don't both utilize. Some things to consider: How they obtain 'food' (what is their organic carbon source?) What structures do they share that prokaryotes lack? What do they share that all living cells also share? Do they use CO2, and/or O2 in any processes?
Answer and explanation:
Although they share some similarities because they are both eukaryotes, plant cells and animal cells are quite different from each other, which is logical since they have distinct lives.
For example, animal cells and plant cells both have a cell membrane, but only the plant cells have a cell wall - which is thick and resistant, and this makes sense because they are more exposed to mechanical and osmotic stress.
Since animals can move towards sources of water but plants cannot, there's also a way in which plants store water in the cells: vacuoles. Animal cells have vacuoles as well although they are much smaller than the single huge vacuole that plant cells have.
All living organisms need the energy to sustain different cellular processes. The organelle in charge of the chemical reactions behind the obtention of energy is the mitochondria, which is present in all cells, but the mitochondrion needs a specific substrate: glucose. Glucose is obtained in diverse ways: animals move and find food that contains glucose in it, while plants produce their own glucose with a specific process called photosynthesis, for which they need an organelle called chloroplast, which animals do not have. In order to transform the glucose into energy, the mitochondria end up generating CO2, which animals expel from their bodies by exhaling. This CO2, now in the air, is used by plant cells as a substrate in photosynthesis (which needs sunlight as well) to produce glucose and also O2, that will be inhaled by animals and used by their tissues.
All living organisms have one thing in common: they possess DNA. DNA contains all of the genetic information of an organism, and it is present in almost every cell of that organism -if it happens to be a multicellular being-. While prokaryotes have their DNA condensed into a single circular chromosome, eukaryotes like plants and animals, have their DNA form many linear chromosomes (quantity varies according to the species) and these chromosomes are inside a very specialized organelle: the nucleus, which prokaryotes do not have.

Animals can help plants reproduce in a variety of ways. Which behavior can end up being more harmful than helpful?
A. Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.
B. Iguanas and tortoises eat leaves, fruits, and flowers, relying on each as important
seasonal food sources.
C. Insects like bees and butterflies drink nectar, carrying pollen from one flower to
another.
D. Hummingbirds drink the nectar of flowers, and they will defend their territory in
order to secure their food supply.
Answer:
B
Explanation:
The behavior that can end up being more harmful than helpful when it comes to plant reproduction is iguanas and tortoises eating leaves, fruits, and flowers as important food sources.
When plant tissues or organs are removed, it affects the reproductive potential of such plants. Thus, Iguanas and tortoises feeding on plant tissues and organs is quite detrimental to plants and may offer very little to no benefits.
Birds help disperse seeds by feeding on fruits and dropping the seeds along with their feces. Insects like bees help pollinate flowers and hummingbirds help protect plants from certain predators. All these actions help plant reproduction.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old
Answer:
The age of the rock is 5 million years
Explanation:
Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16
Number of half-lives undergone by the substance to leave behind 1/16 of the original sample
1/16 = (1/2) * (1/2) * (1/2) *(1/2)
Therefore, the substance have decayed 4 times
One half=life = 1.25 million years
Four half-lives = 4 * 1.25 million years = 5 million years
Therefore, the age of the rock is 5 million years

Compare and contrast characteristics and use his own diodes and triodes
Answer:
Comparison of characteristics and use of diodes and triodes is given below:
Diode and triodes both are electrical components but diode allows the flow of current in only one direction while triode has three electrodes.Diode consists of two terminal (anode and cathode) while Triodes have three terminals (cathode, anode, and grid). A diode is an electrical component used to control voltage while triode is a current controlled device. Diodes used in modern electronics such as LED while triodes are used in RF heating systems.Answer:
1. Conditions that result in the emission of electrons from a conductor:
Heating the conductor to a suitable temperature
Exposing the conductor to a strong light
Subjecting the conductor to a very high applied voltage
Subjecting the conductor to high-speed electrons from another source
2. Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.
