Answer:
A cell that is nonphotosynthetic, such as a prokaryotic bacterium, would not require chloroplasts to function.Explanation:
A broad sweeping eukaryotic plant cell accomplishes the basic functions required for plant care. It's a jumble of organelles held together structurally by the cell membrane, which is located outside of the cell wall.
What is eukaryotic cell?Plant and animal cells are eukaryotic, which means they contain nuclei. Plants, animals, fungi, and protists all have eukaryotic cells.
They typically have a nucleus organelle surrounded by a membrane called the nuclear envelope, which stores DNA.
Prokaryotes are typically simpler, requiring only a few organelles to survive. This is frequently because, as previously stated, it requires less energy.
It has DNA to contain genetic material, ribosomes to make proteins, a cell membrane, and a cell wall to protect the cell from its surroundings. While other components are produced by prokaryotes, the ones listed above are those that may be found in plant cells.
Aside from that, the non-photosynthetic prokaryotic cell requires much less energy, resulting in a cell that is much smaller and less complex than the generalized eukaryotic cell.
Thus, this way, a non-photosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell.

What happens when self-determination mechanisms break down?
Answer:
When self-determination mechanisms break down it mistakes self-tissue as foreign agents and pathogens. This results is Auto-Immune disease.
HOPE THIS HELPS!
When the self-determination mechanisms break down, the body misinterprets its own tissues as foreign antigens, which activates the autoimmune mechanisms to destroy the body's own cells, mistaking them for foreign factors, this happens mainly in mantle autoimmune diseases.
Autoimmune diseases are a group of diseases in which tissue damage is caused by a humoral or cell-mediated immune response to a person's own antigens.
What are antigens ?In immunology, an antigen (Ag) is a molecule or molecular structure or any foreign particle or pollen grain that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body can trigger an immune response. The term antigen originally referred to a substance that is a generator of antibodies. Antigens can be proteins, peptides (chains of amino acids), polysaccharides (chains of monosaccharides/simple sugars), lipids or nucleic acids. Antigens are recognized by antigen receptors, including antibodies and T-cell receptors.

What are the types of neuron ?Neurons basic microscopic unit of nervous system which is responsible for carrying information to different parts of the body by using electrical and chemical signals and coordinate all of the necessary functions of life.
It has three parts such as Soma or cell body which receives information and contain the cell’s nucleus, Dendrites a thin filament which carry the information from other neurons to the soma, Axon is a long projection that carries information from the soma and sends it to other cells.
Neurons involve in impulse transmission can be presynaptic neuron which emits the nerve impulse and the postsynaptic neuron receives this impulse.
Neurons can be Sensory neurons which carry the information from the sensory organs like skin, eyes, ears, nose and Motor neurons, Interneurons form a bridge between two neurons.

Answer:
Explanation:
A paradigm shift is a major change in the concepts and practices of how something works or is accomplished.
A paradigm shift very often happens when new technology is introduced that radically alters the production process of a good or service.
Although the idea of paradigms has been around for quite some time, the concept was explored by physicist and philosopher Thomas Kahn Kuhn.

In a population of frogs, there is a dominant allele H that improves the survival of eggs in moderately dry conditions compared to the wild-type and recessive h allele. Imagine that climate change causes the environment where these frogs live to become more dry. Individuals with the drought-resistant eggs on average have 21 viable offspring per frog per generation, whereas those without that phenotype on average have only 12. If we start off with genotype frequencies of .02 HH, .03 Hh, and .95 hh, what is the average excess fitness of the H allele?
Answer:
8.55
Explanation:
I n the year1908, these two men Godfrey Hardy and Wilhelm Weinberg gave a specification of the relationship between the frequency of genotype and frequencies of allele that should occur when such a population is in equilibrium
p²+2pq+q² = 1
we have,
p² = 0.02
p = √0.02
such that frequency of H is = 0.1414
2pq = 0.03
q² = 0.95
q= √0.95
such that frequency of h =0.9746
(21-12) * 0.95 =
8.55 frogs per generation
H and h will coexist.

You have an Elodea sprig in a test tube containing bromothymol blue. Then you watch it for several days. At what time of day will the oxygen level in the tube be the lowest?
a)just before sunset
b)midnight
c)just before sunrise
d)mid-afternoon
Answer:
c
Explanation:
If you put an Elodea plant in a test tube containing bromothymol blue and watch the oxygen level, the time of the day in which the oxygen level in the tube would be lowest will be just before sunrise.
First, there is a need to understand oxygen is produced as a result of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
The process of photosynthesis takes place in 2 reactions:
Light-dependentLight-independentOxygen is produced from the splitting of water in the light-dependent reaction. Hence, the production of oxygen stops when there is no light - when the sun sets.
Whatever quantity of oxygen that has been produced just before the sun sets would remain and will gradually be used for respiration by the Elodea plant until the sun rises again the following day.
Thus, the level of oxygen in the tube would usually be lowest just before the sun rises and oxygen can be produced again.

C. Build dams, use cars that emit fewer harmful gases, and hat the runoff of factory waste into rivers and streams
D. Increase mining efforts, build dams, and use cars that emit fewer harmful gases
Please Help!!
Answer:
ANSWER IS C
Explanation:
The way by which people positively affect the earth's resources is to build dams, use cars that emit fewer harmful gases, and hat the runoff of factory waste into rivers and streams. So, the correct option is C.
What are Earth's resources?The Earth's resources are referred to as natural resources that are useful raw materials for the manufacturing and production of goods. They occur naturally, meaning that man cannot make them but instead use and modify the resources in ways that are beneficial. Examples include air, water, soil, minerals, fuels, plants, and animals.
Natural resources are not finite but by human activities, such earth's resources become poisonous day by day for our health such as air, water, and soil. So, it's time to beware and spread the message to affect earth's resources positively.
Therefore, the way by which people positively affect the earth's resources is to build dams, use cars that emit fewer harmful gases, and hat the runoff of factory waste into rivers and streams.

body to rid itself of wastes the normal chemical composition of urine is mostly water but it also includes nitrogenous molecules creatine and other metabolic waste units urine is a solution that can be greater than 95% of water what property of water makes watee so helpful in ridding the body of waste
A.water cohesive forces create surface tension upon its surface
B. Water is a versatile solvent
C. Water is expands upon freezing
D.water has a high specific heat
Answer:
B. Water is a versatile solvent
Explanation:
Water is said to possess certain properties that gives it its unique attribute. These properties make it a vital component of life as it makes certain phenomena possible. According to this question, water, which makes up majority of urine content, aids the excretion of certain wastes such as nitrogenous molecules from the body.
Water is able to aid in this excretory function due to its VERSATILITY AS A SOLVENT. Water is said to dissolve more substances than any other solvent. This allows it to transport dissolved substances including waste products out of the body.
