Answer:
They are eukaryotic cells, they present the three main parts: cell or cytoplasmic membrane, cytoplasm and nucleus defined with chromosomes and nucleolus. The three types of cells have in common the following structures: cell membrane, cytoplasm, nucleus defined with chromosomes and nucleolus, mitochondria, smooth and rough endoplasmic reticulum, ribosomes, Golgi apparatus, cytoskeleton and peroxisomes. But it differs in some. The plant cell has chloroplasts and a cell wall and the animal cell does not.
Explanation:
The animal cell has centrioles, lysosomes. It has no plastids, no cell wall, it has vesicles. They do not have the ability to produce their own food from inorganic components. The plant cell has plastids (chloroplasts), cell walls, large vacuoles. Fungal cells are organisms without chlorophyll, therefore they cannot photosynthesize. The reserve substances of the cytoplasm are not starch granules. As they are not able to synthesize their food, they have to obtain from other living organisms (they feed on other plant and animal residues contributing to decomposition) that is, they are heterotrophic. Fungal cells have a cell wall that is not present in animal cells and but plant cells have a cell wall. They have lysosomes and centrioles that the plant cell lacks but they are in animal cells. Animal cells, with a few exceptions, do not have vacuoles while plant cells do. The three types of cells have present nucleus, membrane, mitochondria, endoplasmic reticulum, Golgi system.

A geologist uses relative dating methods to guess that a rock is between 1 million and 5 million years old. What is one radioactive isotope the geologist can use to learn the exact age of the rock?
Answer:
Scientists usually use the potassium-argon method to date rocks that are older than about 1 million years. Uranium-238 is also used for radiometric dating. It has a half-life of 4.5 billion years. It decays to produce lead-206.
Potassium-40 is one radioactive isotope the geologist can use to learn the exact age of the rock, by the use of radiometric dating methods.
What is radiometric dating?This is the process through which geologists can easily use to learn the exact age of the rock, it depends upon the natural radioactive decay of some elements such as potassium and carbon.

what is this answer??
Answer:
50%
Explanation:
Match the statements.
Answer:
PHOTOSYNTHESIS:
- Light energy is absorbed
- Glucose and oxygen are products
- Carbon dioxide and water are inputs
- Chemical energy is produced
CELLULAR RESPIRATION:
- Carbon dioxide and water are outputs
- Chemical energy is released
- Glucose and oxygen are inputs
- ATP, motion and heat energy are produced
Explanation:
- Photosynthesis is process by which autotrophic organisms synthesize their food (glucose) in the presence of sunlight. The process combines carbon dioxide (CO2) and water (H20) to produce glucose (C6H12O6) and oxygen (O2), by the energy derived from absorbing light. In the process, light energy is transformed to chemical energy (glucose). The reaction is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
- Cellular respiration is the opposite of photosynthesis as it involves the metabolic breakdown of glucose molecule to produce energy usable by the cell (ATP). Cellular respiration combines glucose and oxygen (inputs) to yield carbon dioxide and water (outputs). ATP, motion and heat energy are produced in the process. The equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O

Explanation:

Instructions: Look at the motion graphs shown below. Match the descriptions here to the coorect graph.
Description a. A car moving at a constant speed stops and then moves in the opposite dorection at the same speed.
Description b. A car moving at a constant speed stops and then moves faster in the same diresction.
Description c. A car moving at a constant speed changes to a higher constant speed
Description d. A car moving at a constant speed changes to a lower constant speed.
Answer:
A-2
B-4
C-1
D-3
Explanation:
In description A, the car is first moving at a constant speed, which means it will have a constant slope. Then, it stops, which causes a slope of 0. Finally, it moves in the opposite direction, which will cause a negative slope. The second graph has a positive, zero, and negative slope; therefore, it fits A.
Description B has a constant slope, a zero slope, and a higher slope. Graph 4 goes up normally, then stops, and finally goes steeper. This fits description B.
Description C has a constant and then a higher slope. Graph 1, increases steadily and then sharply increases; which fits C.
Description D has a constant and then a lower slope. Graph 3 increases fast but then flattens, which matches the slopes in the description.

it's U because RNA contain Uracil instead of Thymine
Answer:
AAG - GGU - CUA - AAA
Explanation:
This happens because in the RNA synthesis, Thymine is present in Uracil giving it a U symbol. The conversions between the bases go between Cytosine and Guanine, or Thymine (Uracil) and Adenine. Whenever you switch to the other strand, it becomes the opposite base for the other strand so they fit together perfectly in the chromosome or chromatid. Example: C - G contain opposite characteristics that fit so they only go together, Adenine or Guanine will not ever be present with either of those bases.

Gulf of Mexico and the Atlantic Ocean
Atlantic Ocean and the Great Lakes
O O O O
Gulf of Mexico and the Pacific Ocean
O Pacific Ocean and the Great Lakes
Answer:
Gulf of Mexico and the Atlantic Ocean
Explanation:
In North Carolina, there are total seventeen basins. Five basins are present in western region that drains to the Gulf of Mexico and the other river basins drains to the Atlantic Ocean.
11 of the river basins out of total 17 river basins originates in North Carolina and only four basins flow entirely within the state and rest drains to Gulf of Mexico and the Atlantic Ocean.
Hence, the correct option is "Gulf of Mexico and the Atlantic Ocean".

What does convection in water cause?
Answer:
Convection plays an important role in heat transfer inside this pot of water.
Explanation: i hope this is right
Answer:
Convection streams cause the impacts that can be seen in a skillet of water warming on a stove. The water at the foot of the container, closest to the burner, warms quickly and rises to the surface. Bubbles illustrate the disturbance of warmed water atoms, which circulate the warm until all the water is bubbling.

Which category of gymnosperm is thought to have given rise to flower-bearing plants?
Select one:
a.
Cycadophyta
b.
ginkgophyta
c.
Coniferophyta
d.
gnetophyta
Answer:
d. Gnetophyta
Explanation:
Gymnosperms represent a group of "naked seed" plants which includes, among others, Cycads, Conifers and Gnetophytes. It has been proposed that Angiosperms or flowering plants, probably evolved from Gnetophyta about 150 million years ago. Gnetophyte is a group of Gymnosperms composed of only three living genera: Ephedra, Welwitschia and Gnetum. In Gnetum and Ephedra plants, researchers documented a regular process of double fertilization, which is a distinctive feature of Angiosperms. This important observation has been used to propose that Angiosperms evolved from Gnetophyta.
Answer:
Gnetophyta
Explanation:
