The principle chemical compound used by cells to store and release energy is adenosine triphosphate (ATP). It consists of an adenine base, a ribose sugar, and three phosphate groups.
Explanation:
The principle chemical compound that cells use to store and release energy is called adenosine triphosphate (ATP). ATP serves as the primary energy currency of all cells, analogous to how money is used to buy goods and services. The three main parts of an ATP molecule include:
An adenine base, which is a nitrogen-containing compound.
A ribose sugar, which is a five-carbon sugar molecule.
Three phosphate groups, which are linked in a chain and store a significant amount of potential energy.
Cells store energy during the synthesis of ATP (anabolism), and release it when ATP is broken down (catabolism) which then provides the energy needed for cellular activities.

What happens within the cell of a eukaryotic organism when an organelle is no longer functioning properly
Final answer:
When an organelle within a eukaryotic cell fails to function correctly, the cell may utilize autophagy to degrade and recycle the component, or it might trigger apoptosis if the damage is substantial, showcasing the cell's self-maintenance capabilities.
Explanation:
When an organelle within a eukaryotic cell is not functioning properly, the cell can employ several mechanisms to deal with the malfunction. One such mechanism is the autophagy process, where the cell degrades and recycles the damaged organelle. Alternatively, if the damage is too extensive, the cell may undergo programmed cell death, also known as apoptosis, to prevent harm to the organism as a whole. This showcases the cell's ability to maintain internal stability and health, ensuring its optimum functioning within the greater context of an organ or organism.
Autophagy serves as a quality control mechanism, allowing cells to remove malfunctioning organelles and recycle their components, thereby supporting cellular function and health. Similarly, apoptosis plays a crucial role in development and disease prevention by eliminating cells that cannot be repaired. This intricate balance of creating, maintaining, and, when necessary, decomposing cellular components underlines the sophistication of eukaryotic cells.

The reference point for the coordinate (-2, 3) is _____.
A. (x, y)
B. (0, 0)
C. (2, -3)
D. (3, -2)
Answer:
Option A
Explanation:
The point of reference for any co-ordinate point is defined by the co-ordinate frame. In a co-ordinate frame there are six degrees of freedom – three Cartesian co-ordinates and three angular co-ordinates.
Cartesian Co-ordinates – X, Y, Z
Angular Co-ordinates – Rx, Ry, Rz
Angular co-ordinates basically define the rotation of a co-ordinate point about that axis.
In the given question, the co-ordinate point is two dimensional. Hence, its reference point would be x,y
Hence, option A is correct
Which of the following is not true about sedimentary rocks? A. They formed through compaction and cemintation B. They are made up of sediments C.they formed from igneous rock fragments D. They are not part of the rock cycle (15Points!)
The answer is D.
Hope this helps
Answer:
The correct answer option is D. They are not part of the rock cycle.
Explanation:
The rock cycle is the transitional process where the rocks of a particular type change and turn into rocks of another type.
The breaking down of different rocks like igneous andmetamorphic and then the cementation and compaction of these broken rock pieces forms the sedimentary rocks.
Therefore, saying that sedimentary rocks are not a part of the rock cycle would not be true.

Which survivorship strategy is used by the type II species?
Answer:
Type II species include mice, birds and other similar organisms that have constant survivor ship rates as well as mortality rates during the whole period of their expected life/
If we look at survival ship curve of type II species as depicted in attached figure, we can see that it shows a constant slope and contains a straight line. The slope is in such a way that with the passage of time it decreases till reach zero.
The survival ship strategy used by type II species is this that they lie somewhere between semelparous ( comprised by single reproductive episode before death) and iteroparous (comprised by multiple reproductive cycles throughout the lifetime).
They have a probability of dying at constant level therefore they adopt a strategy in between of having more than one and less than multiple reproductive cycle throughout their life. In this way, they maximize their survival span.
Hope it help!

The codons that signal the end of a polypeptide chain are called the terminators.
A codon is a series of 3 DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) nucleotides which corresponds to a particular amino acid or just stop the signals which are sent during the protein synthesis.
The terminators are the codons (also called termination codons) which signal the end of the polypeptide chain during the process of translation.
Green and brown algae share many common features. Both have pigments for trapping sunlight and use photosynthesis for energy. Both store their food as sugars. Both have cell walls and plant-like bodies. However, their DNA suggests that they are not even remotely related to one another. Green algae and brown algae show __________________ evolution, since they look similar, but are not close relatives.
Answer:- Convergent
Explanation :-
Convergent evolution is the process in which the organisms that are not closely related evolve independently in such a way that they acquire similar traits due to similar environment in which they live or the ecological niche that they occupy. Such structures that result from convergent evolution are called as analogous structures, which perform similar function but have different origins. Convergent evolution can be distinguished from parallel evolution in the fact that in parallel evolution similar traits develop in different species which shared a common ancestor and hence, are closely related.Thus, since the brown and green algae look similar but are not close relatives they show convergent evolution.

What is the difference between a population showing exponential growth and a population showing logistic growth? (Site 1)
Population growth refers to the patterns governing how the number of individuals in a given population changes over time. These are determined by two basic factors: the birth rate and death rate.
Answer:
A population can show two types of growth, exponential or logistic. Exponential growth occurs in case of unlimited resources like unlimited food or space. Organisms in the population do not have to compete with each other and the population can grow indefinitely. Such a growth model shows J shaped curve when population size is measured against time.
Logistic growth occurs in case of limited resources and competition. The population has carrying capacity i.e. maximum number of individuals it can hold before the population growth becomes stagnant. This model shows S shaped curve when population size is measured against time.
In real life logistic growth is shown by populations. Exponential growth is not possible since the resources get used up after some time.

If 8.0g of H2 reacts and 72g of H2O is produced how much O2 is consumed in the reaction
Answer:
64 g of O₂ is consumed in this reaction.
Explanation:
Mass of H₂O = 72 g
Mass of H₂ = 8 g
So, mass of O₂ consumed = mass of H₂O - mass of H₂ = 72 - 8 = 64 g
64 g of O₂ is consumed in this reaction.
You breed together a bean plant that has really long, skinny beans and a been plant with really short, fat beans. The offspring end up having medium length, medium width beans. This would be an example of what type of inheritance.
Answer : incomplete dominance
Explanation:
For a given trait, there are basically two types of alleles that are present. One allele is the dominant one and the other is recessive. Generally , the phenotype of an individual corresponds to the one coded by the dominant allele when both the alleles are present for a given trait, that is if a heterozygous condition is there. However, in some cases the dominant allele is not completely dominant over the recessive allele.When the dominant allele is not completely dominant then under heterozygous condition the phenotype expressed is a blend of the phenotypes expressed by both the alleles. For e.g if a red flower is crossed with white flower and we get a pink flower we can say that the allele shows partial dominance over the other. Similarly in the given question, the dominant allele is partially dominant over the recessive allele thus, a blended phenotype appears in the progeny. Such type of inheritance is known as incomplete dominance, partial dominance or semi dominance.What happens when no oxygen is present after glycolysis?

The importance of material transport in plants for photosynthesis
Material transport in plants, specifically through xylem and phloem tissues, is essential for effective photosynthesis. Xylem transports water and minerals to leaves, while phloem distributes photosynthates throughout the plant.
Importance of Material Transport in Plants for Photosynthesis
The process of photosynthesis is vital for the survival of plants and for the production of oxygen, which is essential for most life on Earth. For photosynthesis to occur effectively, plants must have a system to transport materials such as water, nutrients, and photosynthates (sugars) throughout their tissues. The phloem and xylem are specialized transport tissues found in vascular plants that play critical roles in the movement of these essential materials.
Role of Xylem and Phloem in Material Transport
The xylem primarily carries water and dissolved minerals absorbed from the soil up from the roots to the leaves. This water is crucial for photosynthesis, where it is used to split water molecules to release oxygen and electrons needed in the synthesis of glucose. The phloem, on the other hand, transports the soluble organic compounds made during photosynthesis from the leaves to various parts of the plant through a process called translocation. This ensures that photosynthates reach all parts of the plant for growth, energy, and storage.
Water and nutrient uptake often occurs through structures such as dead velamen, rhizoids, and living rhizodermis in plant roots. Moreover, the process of evapotranspiration and stomatal regulation are crucial in managing water transport and preventing water loss, while maintaining the balance necessary for photosynthesis to proceed efficiently.
The “push” needed to start a chemical reaction is the:
enzymatic energy.
endothermic energy.
activation energy.
reactant energy.
its reactant energy, hope this helps :)
The “push” needed to start a chemical reaction is the activation energy. Option C is correct.
Activation energy is the minimum amount of energy that is required for a chemical reaction to start. It is the energy barrier that the reactants must overcome in order to form products. Without activation energy, the reactants would not have enough energy to break their bonds and form new ones. This is why chemical reactions do not happen spontaneously.
Enzymes are biological molecules that can help to lower the activation energy of a chemical reaction. This means that enzymes can make reactions happen faster by providing the necessary energy boost. Endothermic energy is the energy that is absorbed by a system during a chemical reaction. Reactant energy is the energy that is possessed by the reactants before a chemical reaction takes place. Option C is correct.

What is the major difference between the saturated and unsaturated zones
Saturated Zone
[ Completely full of water ]
Unsaturated Zone
[ The pore spaces are not completely full of water ]
The groundwater resource is divided into saturated and unsaturated zones. The saturated is characterized by the water filled in pores, whereas unsaturated is by incompletely filled space.
What are saturated and unsaturated zones?Saturated zones are the division of the groundwater that is found below the rocks and water table. The rocks and the pore space found in this zone are characterized by completely filed water spaces. The fractures and pores of this zone emerge in the groundwater.
The unsaturated zones are found above the saturated zones and just below the soil and land surfaces that are characterized by impartial water spaces. The pores and spaces of this zone are not totally filled with water.
Therefore, the saturated and unsaturated zones differ in water spaces.

What type of organic molecule will be created if alanine bonded with many other amino acids such as serine and glycine
Ans.
The organic molecules that formed by the amino acids are known as proteins. Each amino acid binds with other amino acid with the help of peptide bond between amino group of one amino acid and carboxylic group of another amino acid.
Thus, 'when alanine binds with other amino acids, such as with glycine or serine, a protein molecule will formed.'
Alanine bonded with amino acids like serine and glycine forms a polypeptide. This molecule is linked by peptide bonds through a dehydration synthesis reaction, and its sequence determines its structure and function.
Explanation:When alanine is bonded with many other amino acids, such as serine and glycine, the organic molecule created is a polypeptide. A polypeptide is a long chain of amino acid residues linked together by peptide bonds. Each amino acid is attached to the next by a dehydration synthesis reaction, releasing a molecule of water and forming the peptide bond. The sequence in which these amino acids are linked determines the primary structure of the polypeptide. For example, the sequence Gly-Trp-Ala is distinct from Ala-Trp-Gly because the location of the free amine and carboxyl groups would be different. The polypeptide can fold into complex shapes to form proteins which have variable functions, depending on their amino acid sequence and resultant three-dimensional structure.
