Answer:

Because each the cells would have different functions on different organisms.

Explanation:

Bacteria cells are usually prokaryotic which means that it is only composed of one cell. The single cell already has everything it needs so therefore, it isn't as complex as plant and animal cells.

Plants are autotrophs and produce their own food through photosynthesis. Plant cells would have a large vacuole, cell wall, chloroplasts, unlike animal cells.

Animal cells have all the cell organs that plant cells except a large vacuole, cell wall, and chloroplasts. Animal cells also have lysosomes in which plant cells don't.

Answer:

To increase the rate of the reaction in part C of the above image, change the temperature. Thus option C is correct.

At higher concentration of reactants, more collisions leads to increase the rate of the reaction.

Changing the pressure can change the concentration leads to high number of collisions caused increases the reaction rate.

If a reactant is a solid and  grinding of these reactants can increase the surface area, will lead to faster the reaction.

Increase in temperature, means molecule have higher average kinetic energy and more collision causes an increase in the reaction rate.

The medium in which the reaction occurs is another factor like in aqueous solution the reaction go faster.

Catalysts lower the activation energy followed by increase the rate of a chemical reaction.

Thus option C is correct.

Explanation:

Answer:

carbohydrates, lipids, proteins, and nucleic acids.

Explanation:

Carbohydrates are the primary source of energy. Some are structural, such as cellulose.

Proteins have a wide variety of functions. They make up structures, and regulate chemical reactions as enzymes.

Nucleic acids, DNA and RNA, are involved in heredity and the production of proteins.

Lipids can be structural, such as the phospholipids in the plasma membrane, and they are a source of energy.

Answer:

Globes are used to look at places, without a device. You can think of a globe as a map of the world wrapped up into a ball. If you wanted to look at the United States, you could twist the globe, and see it, and surrounding places like Canada or South America.

The Anartica iceburgs

The polar covalently bonded water molecules act to exclude nonpolar molecules, causing the fats to clump together. The structure of many molecules can greatly influence their solubility. Sugars, such as glucose, have many hydroxyl (OH) groups, which tend to increase the solubility of the molecule.

The water molecule has an irregular distribution of its electrical charges and it is this irregularity that allows this molecule to be polar and able to solubilize other polar substances.

This can be explained as follows:

With the irregularity of the electrical charge, water becomes a substance that can form bonds with positive and negatively charged molecules, which guarantees the solubility of a wide range of substances.

Some water-soluble substances are acids, ionic solids, gases, sugars, proteins, salts, among others.

Answer:

they do not dissolve easily

Answer:

Nonpolar molecules do not dissolve easily in water. They are described as hydrophobic, or water fearing. Water's hydrogen bonds create an environment that is favorable for polar molecules and insoluble for nonpolar molecules

The spines of a cactus are exactly not the leaves, but they are the solid hard part that reduces the rate of transpiration, so as to level the water constant in the cactus' body. They are important as it can reduce the animals from eating the cactus.

However, camels have thick jaws and can eat cactus easily .

Ans=> In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. ... Parts of a cell. A cell is surrounded by a membrane, which has receptors on the surface

2) Write it's functions ?

Ans => They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function

Answer:

Erythrocytes. They are red blood cells that travel in the blood. Their characteristics of being red, round, and like rubber give them the ability to complete their specific functions. They carry oxygen from the lungs to the body and bring carbon dioxide from the body to the lungs.

Phospholipids : This makes up the bi-layer which is the membrane's basic structure and has great control over what can enter and exit the cell, due to their hydrophobic tails and hydrophilic heads.

Cholesterol : This also controls entry and exit of substances as it also exhibits hydrophilic heads and hydrophobic tails. It also stabilises the membrane and affects its fluidity (the more there is, the more fluid is the membrane.)

Glycolipids : Those can act as receptor molecules (essential for cell-signalling), antigens and in cell-adhesion

Answer:

glycerophospholipids

Explanation:

With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

Answer:

adverse effect on human and enviroment.

Explanation:

UV radiation generates ground-level ozone (o3) and dome particulate matter( PM frequently called aerosol ) that include nitrate, silfate and organic aerosols causing adverse effects on humans and the environment. UV promotes the formation of hydroxyl radicals that act as cleaning agents for the troposphere.

Three catastrophic results of radiation on the environment are :

The results of heavy UV radiation on the environment can lead to the degradation of the environment and pose a significant health threat to Humans as well in the environment. some of the results of radiation includes the formation of organic Aerosol which can pose health threat ( Lung diseases ) to humans. while hydroxyl radicals acting as cleaning agents in the troposphere damages the atmosphere as well.

Heavy atomic blasts is an example of heavy radiation which can lead to skin burns and Cancer in Humans.

The earth’s core affects the shape of the ground we

walk on.

Explanation: The earth’s core is responsible for

not only the Rocky Mountains, but the formation of cities and societies that have lived there for

generations, such as Rocky Mountain National Park. It’s responsible for mountains that serve as barriers,

bringing to life divisions in culture unique to each side, while also posing a challenge to be crossed and

burrowed into, spurring on scientific innovation in the process.

The Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.

The Earth's core may be defined as the innermost layer of the Earth which is very hot and dense.

The Earth's core is responsible for any geographical locations like mountains, deserts, biodiversity hotspots, rivers, etc. It gives a structural appearance to the Earth. Human life is widely impacted and depends on all of these locations for their needs. All these geographical locations determine the climate of that particular area which is responsible for those people who are living at that location. Human life takes all its requirements from this core surface only.

Therefore, the Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.

Answer:

1.Natural Selection

2.Overproduction

3.Variation

4.Struggle for existence

The steps in the theory of Darwin should be performed in the following order: Overproduction, Natural Selection, Variation, and the Fight for Existence.

Thus, the following sequence can be used to number the steps in Darwin's theory, which involves variation where people within a population display innate variances in their attributes. This step is followed by overproduction, when an organism produces more children than the environment can sustain, resource competition results.

People within a population battle for survival because of overproduction and a lack of resources. The last step is natural selection, which involves people having advantageous mutations that suit their environment better have a higher likelihood of surviving and reproducing successfully.
