Which of these statements could BEST describe the differences between the electron transport chain in cellular respiration and photosynthesis?
A
The electron transport chain in photosynthesis needs a source of energy to start with, and the one in cellular respiration does not.
В
The electron transport chain in cellular respiration releases ATP, and the one in photosynthesis does not.
C
The electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not.
D
The electron transport chain in cellular respiration uses NADH, and the one in photosynthesis does not.
Answer:
c
Explanation:
etc uses oxygen
photosynthesis uses carbon dioxide
The best statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.
What is Photosynthesis?Photosynthesis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.
Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products. Splitting water into oxygen gas, hydrogen ions and electrons produces the energy for subsequent electron and proton transport and provides the energy to produce the sugars the plant needs.
The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.
Therefore, The best statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.

When is the kinetic energy of a pendulum the least?
Question 5 options:
Half the distance on the path traveling back down.
On the path beginning the upwards swing.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
Answer:
The answer is D. At the top of the swing where it briefly stops before changing direction.
Explanation:
When the pendulum is either at its far right or left position, the bob is at rest and therefore its kinetic energy is equal to zero- making it the lowest point of kinetic energy during the whole process.
Answer:
The answer is C
Explanation:
because when your on the swing the most kinetic energy is where you start to go to the upwards part right when the drop happens
it allows you to swing up very high making the option C correct

The ________, which stains dark as it contains pigments and blood vessels, is just underneath the retina.
The choroid stains dark as it contains pigments and blood vessels. It is
located underneath the retina. It also lies between the retina and the sclera.
The choroids are very rich in connective tissues( blood vessels) which help
supply the retina with vital nutrients needed for proper eyesight.
The choroids are usually thickest at the extreme rear end of the eye and also helps to maintain a constant eye temperature and volume. This is
important to prevent changes in eye size and temperature which may cause

Which term refers to the microscopic physical gap between the presynaptic and postsynaptic neurons at a chemical synapse
The gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.
The neurons are the smallest units of the nervous system. They are equally referred to as the nerve cells.
The presynaptic neurons that receives the fired action potential through its axon terminals.
This leads to release of neurotransmitters found in the synaptic vesicles of the presynaptic neurons.
These neurotransmitter are released into the physical gap between the presynaptic and postsynaptic neurons called the Synaptic cleft.
The neurotransmitters are then received by the postsynaptic neurons.
Therefore, the gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.

S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?
S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.
S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.
In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.
It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.

in the Fall of the year, leaves appear red, orange, yellow and brown because the chlorphyll decreases in the leaves and allows the --(blank)-- pigments to reflect mostly colors other than green.
possible answers than can go in the blank are primary or accessory
The appropriate word to fill into the blank would be accessory.
In the Fall of the year, leaves appear red, orange, yellow, and brown because the chlorophyll decreases in the leaves and allows the accessory pigments to reflect mostly colors other than green.
The core pigment in leaves that makes them appear green is chlorophyll. The pigment is primarily responsible for absorbing light energy to drive the photosynthetic process in plants.
Some other pigments, also known as accessory pigments such as carotenoids, anthocyanins, xanthophylls, etc., help out chlorophyll in some ways but have colours that are different from green.
Thus, the appearance of other colours such as orange, yellow, brown, etc., on leaves is due to a decrease in chlorophyll and the reflection of the colours of the accessory pigments.

The most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens is cleft palate at 8 weeks gestation. It is an opening in the roof of the mouth.
A teratogen is any substance and/or physical agent that may cause an irreversible abnormality in the structure of the developing embryo or fetus (e.g., classical pesticides such as DDT).
Cleft palate is a malformation mainly caused by mutagenic agents (teratogens) during pregnancy, which affects approximately one (1) of 650 births.
A cleft palate is a malformation that occurs when the two plates of the skull that form the roof of the mouth cannot be completely joined.

Give two ways that differentiation is the same in plants and animal.
Differentiation in plants and animals involves the specialization of cells for specific functions, and it results in the development of different tissues and organs.
What is differentiation in plants and animals?Differentiation refers to the process by which cells become specialized in structure and function. In plants and animals, this process occurs during development and results in the formation of different types of cells, tissues, and organs.
During differentiation, cells undergo changes in gene expression, which leads to the production of different types of proteins and other molecules. These changes can be triggered by various signals, such as hormones, growth factors, and environmental cues.
In animals, differentiation occurs during embryonic development and results in the formation of different types of tissues, such as muscle, bone, and nerve tissue. In plants, differentiation occurs during both embryonic development and growth and results in the formation of different types of tissues, such as root tissue, leaf tissue, and stem tissue.
