what is a defining characteristic in eukaryotic cells? What type of organisms have eukaryotic cells
Answer:
The defining feature of a eukaryotic cell is the presence of a nucleus. Most animals and plants have eukaryotic cells.
Explanation:
Eukaryotic cells have a nucleus, and membrane-bound organelles All multicellular organisms are made up of eukaryote cells
Eukaryotic cells are one of the two types of cell types prokaryotic and eukaryotic. There are various structural and functional differences found in them.
Eukaryotic cells are defined by:
the presence of a nucleus enclosed by a complex nuclear membranepresence of membrane-bound organellescell wall may or may not be presentcell division is mitosis or meiosisEukaryotic organisms have various range of organisms including mostly all multicellular such as animals, plants, fungi, and protists, as well as most algae. Eukaryotes can be single-celled as well.

If there is moisture in the atmosphere as the front (pictured) comes through, what effect could it have on temperature and weather?
(ANSWER FAST!!)
Answer:
c)The temperature would decrease and there would be a chance of thunderstorms.
Explanation:
The temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.
What is Thunderstorm?A thunderstorm is defined as a storm with lightning and thunder produced by a cumulonimbus cloud, usually producing strong winds, heavy rain, and sometimes hail. Thunderstorms are so called because of the thunderous loud noise they make.
There are three basic elements that lead to the development of thunderstorms: moisture, an unstable atmosphere, and some way for the atmosphere to move where the moisture is necessary to produce thunderstorm clouds and precipitation.
Thus, the temperature would decrease and there would be a chance of thunderstorms. So, the correct option is C.

Vernon is using the diagram shown below to develop a model of photosynthesis. The letters A, B, and C each represent a reactant or product of the process.
In the light-dependent reactions, light strikes the oval thylakoids. Compound A enters the thylakoid, and compound B leaves it. In the light-independent reactions, compound C enters a cycle in the stroma, and sugars leave the cycle. ATP and NADPH cycle between the two sets of reactions.
Should water (H2O) be included in the model as a reactant or product? If so, how should it be included?
A. Yes, as reactant A.
B. Yes, as product B.
C. Yes, as reactant C.
D. No, it should not be included.
Photosynthesis is the process of preparing food in the presence of light, water, and carbon dioxide. Photosynthesis can be light-dependent or light-independent reactions.
The correct answer is:
Option A. Yes, as reactant A.
The mechanism can be explained as:
1. Light-dependent reactions convert light energy into chemical energy.
2. The light-dependent reactions require water and light to yield oxygen, hydrogen, and energy molecules.
3. The light is used to break down the molecule of water into oxygen and hydrogen when the light strikes the thylakoid.
4. The ATP is generated in the stroma of the thylakoid membrane. The excited electrons released during the splitting of water is utilized to produce high-energy molecule.
Thus, water molecule should be used as a reactant because it yields products.

What is difference between unicellular and multicellular organisms?
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore, all cells have a cell wall but only plant cells have a cell membrane. The given statement is false.

Which statement accurately describes sickle cell anemia?
Answer:
Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body
Explanation:
Answer:
A group of disorders that cause red blood cells to become misshapen and break down.
Explanation:
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anemia), and can block blood flow causing pain (sickle cell crisis).Infections, pain, and fatigue are symptoms of sickle cell disease.

Which of the following describes what might happen with a sudden increase in precipitation in the grassland biome? (4 points)
a
Rise in drought-tolerant plants
b
Salt and sediment deposition
c
Increase in plant and animal diversity
d
Nutrient loss and soil erosion
Increase in plant and animal diversity describes what might happen with a sudden increase in precipitation in the grassland biome. Therefore, the correct option is C.
What is precipitation?Precipitation is the phenomenon in which condensed water vapors falls on the earth's surface under the influence of gravity.
A sudden increase in precipitation in the grassland biome can provide more water for plants and support their growth, which can lead to an increase in plant productivity and diversity. This in turn can provide more food and habitat for animals, leading to an increase in animal diversity as well.
While there may be some nutrient loss and soil erosion as a result of increased runoff, the overall effect on the ecosystem is typically positive in terms of increased biodiversity. Salt and sediment deposition are not typically associated with an increase in precipitation in the grassland biome. Therefore, the correct option is C.

The pancreas is an organ present in some animals. It produces enzymes that are used in the digestive system of the animal. Which cell structure is likely to be abundant inside pancreas cells?
A. Cell walls, because cell walls cannot be digested by enzymes
B. Chloroplasts, because chloroplasts provide the energy for making enzymes
C. Nuclei, because nuclei contain the instructions for synthesizing enzymes
D. Ribosomes, because enzymes are synthesized on ribosomes
Answer: the answer is D Ribosomes, because enzymes are synthesize on ribosomes
Explanation:
Because we need more protein to be produced in are pancreas
The messenger RNA (mRNA) sequence is read by the ribosome, which then interprets the genetic code into a predetermined string of amino acids. These amino acids then form lengthy chains, which fold to form proteins. Thus, option D is correct.
What is the role of ribosomes in the enzyme formation?Protein synthesis is always carried out by the ribosome, which converts the genetic code produced in mRNA into an amino acid sequence.
Ribosomes carry out the initiation, elongation, and termination of peptide synthesis using metabolic energy, soluble transfer RNA's, and cellular auxiliary proteins.
The biocatalyst, which are proteinaceous in nature, are enzymes. The ribosomes found on the endoplasmic reticulum produce these. A cell's ribosomes are referred to be its “protein factory.”
Therefore, Ribosomes, because enzymes are synthesized on ribosomes.
