Because all living things are made of cells,
and you are a living thing, what kind of
cells are you made of?
(Prokaryotic or eukaryotic)
Answer:
eukaryotic
Explanation:
Well, there are some prokaryotic cells in the body, but mostly its eukaryotic, and the human body is categorized as eukaryotic organisms, because eukaryotic means that the cell has a nucleus, where prokaryotic cells don't.
How did the number of organisms change between 1900 and 2010
Answer:
the number of prey and predators has decreased
Explanation:
this is because of increased rate of hunting .the prey such as elephants and rhinos are being hunted for their horns while predators are also being hunted because of their skin.
also due to man and wild animal conflicts which happen in areas nearing the forests ,both prey and predators are killed.

3. Which of the following is a defining characteristic of a prokaryotic cell?
a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement
Answer:
C
Explanation:
Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.
The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.
What is a prokaryotic cell?Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.
They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.
The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.
Therefore, option C. the prokaryote lacks a membrane-bound nucleus.

7. Why is the property of specific heat important to aquatic life?
Answer:
Specific heat means amount of heat required to raise a temperature of a particular body, in case of aquatic life the specific heat plays an important role, the organisms living in an aquatic system require an certain body temperature to be maintained in order to survive.
Specific Heat raises the temperature of the water body resulting in Aquatic life to survive.

How can atoms get a full (maximum energy) outer shell?
Answer:
Explanation:
One easy way for atoms to achieve a full outer shell is to share electrons in their outside, valence shells. When atoms share their valence electrons, they form a molecule with covalent bonds. One pair of electrons makes one covalent bond.
If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is ______ compared to the cell.
A: hypertonic
B: none of the above
C: isotonic
D: hypotonic
Answer:
it would be A: hypertonic
If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is hypertonic compared to the cell.
TONICITY:
Tonicity is the ability of a solution to induce movement of water in and out of a cell. Tonicity can either be hypertonic, hypotonic or isotonic in nature. Hypotonic solution is a solution that is lesser in solute concentration compared to the cellular solution while hypertonic solution is a solution that is greater in solute concentration compared to the cellular solution. This means that the glass of water with 20% salt is hypertonic (higher in concentration) to the cell containing 5% salt.Learn more about hypertonic solution at: https://brainly.com/question/8984839?referrer=searchResults
Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
Answer:
Oxygen cycles keeps the flow of oxygen at a constant rate.
Explanation:
The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.
Answer:
A.) The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.
Explanation: Hope this helps!!
Why don’t we have a complete fossil record of all life that’s ever lived?
Answer:
Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.
Explanation:
For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.
Please mark me as the brainliest
Answer:
Sediment has to cover the bones in order for fossilization to take place
Explanation:
Fossil formation requires a mix of physical and biological conditions. Fossils have to be exposed in oder to find them too, so there might be some that are just too deep in the earth for us to find them

transformed by the process of photosynthesis.
А
et your pas
Primary productivity
B
Gross primary productivity
С
Net primary productivity
D
Cellular respiration
Answer:
C. Net Primary productivity
Explanation:
In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.
The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R
Where, R = energy lost via respiration.

Which description refers to short-range forecasts?
cover five days or less
do not require computers
cover more than 10 days
impacted by butterfly effect
Answer: Cover five days or less
Explanation:
Cover five days or less is the correct answer because in short range forecasts , high goals models are Majorly used for this and are Majorly the atmospheric model which require the use of high quality personal computers and these PCs normally require five days to foresee guage of the independent model investigation and short range conjecture normally require 0.5 to 2.5 days which normally use to get the isobar or weight.
Therefore, short range forecast cover 5 days or less.

Do fungi have cilia, flagella or pseudopodia for locomotion?
i) Yes
ii) No
Answer:
Yes
Explanation:
Cilia and flagella are also known among plants and animals, although they are absent from the true fungi. In some protists, single cilia have, in effect, been replaced by compound ciliary organelles (e.g., membranelles and cirri), which may be used effectively in locomotion and feeding.
