Describe a challenge that would be encountered and a success of one of the new rats to another new environment (example: the rat living on Island B now moves to Island D).


Island A
The island is fairly flat with an occasional hill. The ground is made of soft dirt, and several species of shrubs grow toward the center of the island. There is no animal life on land, but the water around the island is teeming with fish. The island is surrounded by a coral reef, and the shore is sandy with no algae growing on it. Freshwater is available.
Island B
This island has a rocky shoreline. Numerous tide pools dot the island along the shore where the wave action is somewhat sheltered by rocky outcrops. The tide pools host barnacles, abalone, sea urchins, and crabs. Algae grow all around the island; however, the growth of algae is quite sparse in the tide pools where the various animals feed. The current is quite strong along the rocky outcrops where the algae grow best. Freshwater is available.
Island C
The island is somewhat barren. A few species of cactus thrive on the bare rocks, and a large, cactus eating tortoise inhabits the island. A species of very large birds nests on the island annually. The birds build their nests on the rocks and protect their eggs from the sun by standing over the nests with outspread wings. The nests are always found on the windy side of the island, which is somewhat cooled by offshore breezes.

Island D
This island is an extinct volcano. Vegetation on the island changes as the altitude increases. Grasses grow at the base of the volcano, but farther up the volcano’s slope, the grasses give way to low shrubs. Halfway up, the island becomes quite lush; tropical plants and trees dominate the landscape. At this altitude, the island experiences frequent rain showers. Two species of birds inhabit the island. One is a raptor that preys on the smaller birds. The other fishes the waters approximately one mile offshore. Both of the bird species nest in trees.

Answer: A chemical bond that involves electron pairs being shared between atoms is called a covalent bond.

Answer:

No

Explanation:

The mutation is not expected to affect all the proteins produced in Sam's cells because each protein has a different structure and functions. Proteins are polymers of amino acids and the component amino acid for each protein diffesr. Hence only the proteins whose constituent amino acids include the amino acid being carried by the mutated tRNA would be affected. Others whose constituent amino acids do not include the amino acid being carried by the mutated tRNA would function normally.

Explanation:

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.

Answer:

functions as adhesion and address loci for cells.

Carbohydrates protect the cell by forming a glycocalyx, which is especially strong in bacteria and enables biofilms to form.

Explanation:

Answer:

A

Explanation:

The statement that is true about cells are;

- cells come in different shapes and sizes

- cells are considered the basic structural unit

- cells are found in every living thing

- cells are not limited to only a particular size, they have various size and shapes, this is because each cell perform a specific function and as such, they tend to have a different sizes

- cells are considered the basic structural unit of all living things, both plants, and animals, they both depend on cells to survive

- cells are found in every living thing(plants and animals) they perform vital functions

Answer:

Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:

all organisms are made up of one or more cells,

all the life functions of an organism occur within cells,

all cells come from preexisting cells.

Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:

all known living things are made up of one or more cells,

all living cells arise from pre-existing cells by division,

the cell is the fundamental unit of structure and function in all living organisms,

the activity of an organism depends on the total activity of independent cells,

energy flow (metabolism and biochemistry) occurs within cells,

cells contain hereditary information (DNA) which is passed from cell to cell during cell division,

all cells are basically the same in chemical composition in organisms of similar species.

The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

Hope I helped!

According to the unified cell theory, all living things are made up of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Later, Rudolf Virchow made significant contributions to this theory.

Answer:

Explanation:The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. ... Cellular respiration releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.

Answer:

pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution

A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.  When a solution is neutralized, it means that salts are formed from equal weights of acid and base. i hope this helps you

Answer: A wedge is basically an incline plane. Often portable used for many purposes

Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.

In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.

The wedge works on the principle of an inclined plane.

The Door Stop Is an example of one,

A Knife is a very thin wedge because it slices through objects

Chisels are used to dig into stone and chip away at it to create sculptures.
