Explanation: The surface area to volume ratio is a critical factor in deciding the ability of a cell to take in nutrients through a passive transport process such as diffusion.

Model A has a lower surface area to volume ratio while B has a greater surface area to volume ratio.

Onion root tips are often used to study mitosis because they grow very rapidly, which means that many cells are dividing. The very tip of the onion root ends in a structure called the root cap. The other end of the root attaches to the onion. A scientist is interested in determining whether an onion root tip grows from the base of the root or from the tip near the root cap. She counts the number of cells that are in one of the phases of mitosis at different distances from the root cap. What is the dependent variable in her experiment

Answers

Answer:

- Dependent variable: number of cells that are in one of the phases of mitosis

Explanation:

In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.

extinction, in which ecosystems change drastically

Explanation:

The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.

On the basis of evolution, organisms are classified as primitive or evolved organisms. Organisms that have a primitive cellular design are termed as prokaryotes, while organisms that are evolved and have a complex cellular structure are called eukaryotic organisms. Eukaryotes may either be unicellular or multicellular in the organisation and are further classified on the basis of similarities and differences in the body design, mode of nutrition and development.

In the plasma membrane, the phospholipid heads Group of answer choices are hydrophilic and face inward, shielded from water. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane.

Answers

Answer:

are hydrophilic and face outward toward the aqueous solution on both sides of the membrane

Explanation:

The plasma membrane is structurally made up of a phospholipid bilayer, which is amphipathic in natire. This means that the phospholipid layer of the plasma membrane consists of phosphate head that is water loving or hydrophilic in nature and a lipid tail that is water fearing or hydrophobic in nature.

Since the phosphate head is HYDROPHILIC, they face outward toward the aqueous (water) solution on both sides of the membrane. This allows the phosphate head to attract water molecules.

Highlight all the atoms of the four functional groups, but do not highlight any bonds. When you click on each atom, it will change color. To deselect an atom, click on it again. Before you submit, check that you have not selected any bonds.

Answers

Hi. You did not submit any image, table or description of a molecule for the functional groups to be pointed out. This makes it impossible for your question to be answered. However, I will try to help you as best I can.

A functional group is a set of atoms of different chemical elements that take the place of a hydrogen atom that was part of a hydrocarbon (it is a molecule composed of carbon and hydrogen atoms). The most common functional group is −OH, but you also often encounter −SH, −NH2, and −OPO2−3 functional groups.

how is classification of animal related to its adaptational features

Answers

Answer:

it is important because it helps us identify and name all the animals on earth

Answer:

We can classify organisms on the basis of its physical features.

Explanation:

Classification of animal is related to its adaptational features because adaptational features of an organism provides information about the organism to which specific kingdom or phylum the organism belongs. These adaptational features are gained by the organisms due to different environmental as well as climatic conditions the organism have which make changes in the body features of an organism. So we can classify organisms on the basis of its physical features.

Luisa went into the bathroom after her sister had a bath. It was full of mist and the mirror was covered with the a lot of liquid drops. What was the mist made of?

Answers

Answer:

Mist is made of water vapor.

Explanation:

The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.
