Answer:
We got a chance to speak to Noah the Ark builder. Many people of the town have been wondering what Noah has been building lately. We asked him what was his objective and he said "A great flood like no other will come, water from the sea will fall from the air. Whoever is in the ark shall be safe. Two of each type of animal on earth shall come to my ark for shelter. The storm will be so great it will knock out all who does not inhabit the ark."It is hard to understand what he means by these statements but who knows maybe his boat will take him somewhere. The people of the town have been calling him insane, since no one would need a boat that big.
(I'm guessing that you mean the interview was before the flood since everyone died after.)

What is an Adaptation?
Answer:
The way something changes to fit its natural environment or surroundings to have a better chance at success for anything
Explanation:
how is classification of animal related to its adaptational features
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.

Eliminate B) Air, water, heat and noise pollution can all be caused by producing and using technology. C) Scientific research has led to widespread increases in carbon emissions which has led to global climate change. D) Scientific research has caused widespread habitat disturbance and destruction as scientists have invaded ecosystems. E) Manufacturing technology creates large amounts of waste, and used computers and electronics get thrown out when they break or become outdated.
Answer:
Option B and E and D
Explanation:
Technological advancement has led to growth of industries and manufacturing units and hence the net production of goods. This has led to the use of natural resources and release of pollution of all forms. Environmental research leads to intrusion into niche habitats and hence causes its destruction.
Option B, D and E are correct
Changes in global temperature and other Choose... conditions have effects on organisms and on the clades to which they belong. The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of a Choose... pattern. This pattern includes Choose... extinction, which tends not to disturb ecosystems, as well as Choose... extinction, in which ecosystems change drastically.
Answer:
larger macroevolutionary patterns.
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.
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?
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.

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.
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.
Models are useful because
Answer:
because they are copies of actual object or actions.

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.
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.

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
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.
Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?
Answer:
The correct answer is - Disruptive selection.
Explanation:
Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.
In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.
