Answer:
C.
Explanation:
Because for answer A, only eukaryotes have DNA, also for B, only eukaryotes have a nucleus and lastly, for D, only eukaryotes contain membrane-bound organelles. hope this helps :)
Both cell types undergo cell division by mitosis. Therefore, option (C) is correct.
What are eukaryotic and prokaryotic cells?A nucleus and other membrane-bound organelles are exclusively found in eukaryotic cells, which is the main distinction between prokaryotic and eukaryotic cells. Prokaryotes and eukaryotes, respectively, are made up of prokaryotic and eukaryotic cells. Eukaryotes often have several cells, but prokaryotes are invariably unicellular. Eukaryotic cells are also between 100 to 10,000 times bigger and more complicated than prokaryotic cells.
Prokaryotic DNA is kept in the cytoplasm, while DNA in eukaryotes is kept in the nucleus. Additionally, double-stranded chromosomes that are compressed by histones are where eukaryotic cells store their DNA. Prokaryotic organisms, on the other hand, only contain one basic circular chromosome and a variety of plasmids, which are tiny DNA rings. In comparison to prokaryotic cells, the DNA of eukaryotic cells contains a higher percentage of non-coding DNA and proportionately less coding DNA.

A. greenhouse effect
B. acid rain
C. radioactivity
D. extinction
Answer:
A. greenhouse effect
Explanation:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Climate change results from the shedding of gases like CO2 into the atmosphere where it can trap more heat.

An organism that reproduces sexually has a diploid number of 30. How many
chromosomes will a gamete of this organism have?
Answer:
Gamete of organism has a haploid number of chromosomes.
2n = 30
n = 15
A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.
After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Explanation:
agonists generally _______ activity at the synapse while antagonists generally ______ activity at the synapse.
Agonists activate the receptor thereby increasing activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby decreasing activity at the synapse.
An agonist is the component that has the ability to increase the activity carried out by another substance.The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.

what energy carrying molecule is created when the chemical bonds of glucose are broken
By oxidizing glucose and other dietary molecules in a step-by-step manner, ATP and NADH are produced as chemical energy.
What is ATP?
A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers energy to cells by releasing its phosphate groups when it interacts with enzymes like ATP triphosphatase.
By adding a phosphate group to another molecule, ATP can drive biological operations (a process called phosphorylation). Special enzymes are responsible for carrying out this transfer, which connects the cellular processes that need energy to the release of energy from ATP.
A variety of cellular functions, such as ion transport, muscular contraction, the transmission of nerve impulses, substrate phosphorylation, and chemical synthesis, all require energy and hence use ATP. A large demand for ATP is generated not just by these processes but also by others.

Which process occurs at location W? precipitation evaporation condensation transpiration.
Answer:
Precipitation
Explanation:
If it's the graph that I am thinking of, then it is precipitation. This is where raining occurs in he picture.
The biogeochemical cycle where the water circulates from the atmosphere to the Earth surface in a continuous motion is called the water or hydrological cycle.
The process that occurs at location W is:
Option A. Precipitation
The water cycle can be explained as:
The water cycle has four main components that are evaporation. condensation, precipitation and runoff.When an atmospheric substance falls on the ground in the form of rain, snow hails etc. are called precipitation.When the water from surfaces turns into vapours and moves upwards in the atmosphere is called evaporation.The vapours in clouds turn into water droplets ready to fall as rain or snow is called condensation.Transpiration is a plant function in which surplus water is exhaled from the stomata of the leaf.Therefore, the water cycle shows precipitation.

Compared to other routes of administration, ________ is the most complicated way for a drug to enter the bloodstream.
Answer: the answer is oral consumption
Compared to other routes of administration, oral consumption is the most complicated way for a drug to enter the bloodstream.
How many ways can drugs enter the bloodstream?Substances can enter the body in different ways. Drugs can be smoked, inhaled, injected, swallowed (tablets, capsules, liquids), or applied transdermally (applied to the skin). Most of the drugs are taken orally and broken down in the gastrointestinal tract. Once the drug arrives, it is broken down by stomach acid before passing through the liver and into the bloodstream. Medicines can be taken in a variety of ways, including swallowing, inhaling, absorbing through the skin, and injecting. Each method has advantages and disadvantages, and not all methods can be used with all drugs. After the tablet is swallowed, it is usually absorbed through the stomach wall into the blood. These take effect within minutes, but usually take 1-2 hours to reach peak blood levels.To learn more about medication, refer

Describe how scientists make inferences on whether water is polluted or not
Answer: Water that's safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn't necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.
Explanation:
Drinkable water should ideally be transparent and taste and smell normal. Look for turbidity, or cloudiness, as one indicator that water is contaminated.
What is drinkable water?Surface water and groundwater are the two sources of potable water, also referred to as drinking water. The level of treatment applied to this water satisfies both state and federal standards for potable water.
The indirect potable reuse (IPR) and direct potable reuse (DPR) processes are the two basic ways to turn wastewater into potable water (DPR).

The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?
A. bbTT X BbTt
B. BBtt X BBTT
C. bbtt X bbtt
D. BbTt X BbTt
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
