Why is there variation (differences) between the phenotypes of our protein pals?

*Use the following terms in your answer: Nitrogen Bases, DNA, Protein*

Answers

Answer:

Explanation:

Proteins are large molecules made from amino acid. During protein synthesis, a sequence of three DNA or mRNA nucleotides (that are usually denoted with the nitrogenous bases of the nucleotides) correspond to different amino acids. These sequence of three are called codons which eventually code for different amino acids and the amino acid sequence, on its own, forms proteins. Different amino acid sequence forms different proteins thus leading to phenotypic variation of our protein as said in the question

Infiltration is the process in which the water seeps into the soil surface. Thus, option B is correct.

What is Infiltration?

Infiltration is an important phenomenon that defines percolation of water in the soil. It is important for maintaining the ground water level.

The water seeps down into the soil gradually through capillary action. Infiltration is mostly observed during a rainfall.

Infiltration takes place till the soil accomodates maximum water. Beyond that, infiltration will stop as the soil is said to be saturated with water.

Infiltration is measured in inches per hour. It is the depth of water enters into the soil in an hour.

Infiltration rate is determined by various factors. Soil porosity and texture of the soil is one such important factor for water infiltration.

Porosity of the soil can be deteriorated through human activities. Large pores hinder percolation of water.

Infiltration is also determined by the intensity and duration of precipitation.

Therefore, infiltration is important for increasing the water table for further water storage.

B.
arachnids, crustaceans, myriapods
С
crustaceans, insects. molluscs
D insects, myriapods, nematodes​

Answers

Answer:

Arachnids, crustaceans, myriapods.

Explanation:

Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.

At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.

There was a nearly intact fossil of a hadrosaur called Dakota. How did this find change our knowledge of the hadrosaur? List three specific ways.​

Answers

Answer: Environment, skin coating, and perhaps seasonal migration.

Explanation: The hadrosaur has become an unmistakable species due to its unusual bill, and bipedal legs. However this new fossil could change many studies. First off, environmental hazards. Due to the amount of carnivorous fossils found in the Dakota area, finding a nearly intact fossil of any sort should be quite impossible. This brings paleontologists to believe hadrosaurs may have had some sort of defense against predators, which brings us to skin coating. To be found in such an arctic area must have meant it would be difficult for anything herbivorous to live in the area, unless feathers, or fur was involved. This could change every theory about the so called scaly beasts we refer to as dinosaurs. This brings us to our final topic, migration. Every winter if you were to go outside, it would be highly unlikely to hear birds. This is known as migration, a period when certain animals of multiple species, typically birds, move to warmer areas for the winter. Consider if the birds descending from dinosaurs theory was correct. This could in fact be how birds somehow get this preconceived notion to migrate. This, just as wild dogs are naturally aggressive, could be instinct.

How would you difference between pollen cells and algae cells?

Answers

Answer:

The difference between the given terms is summarized below.

Explanation:

Pollen cells:

Single or perhaps even more vegetative cell lines as well as a reproductive cell come in the form of pollen. The masculine gamete is not a pollen crop on its own.

Algae cells:

There will only be a singular nucleus throughout many of these algal cells, whereas other cells have become multi-nucleate. Furthermore, several other algae were indeed saponaceous, which means that cell walls aren't differentiated from one of the several nuclei.

The differentiation between pollen cells and algae cells can be seen from the habitat in which they thrive and their structural characteristics.

The pollen cells are reproductive structures in a plant that gives rise to the male gametophyte that houses the male reproductive cell of a plant. During pollination, they are being transferred to the stigma by to the presence of spikes around the pollen cells which attaches to the bees (an agent of pollination).

The algae cells are single or multinucleate eukaryotic cells, that live in swampy and wet habitats. The presence of the tail in the cells helps in the locomotion of the cells to the area where their fertilization takes place.

In a group of water molecules, hydrogen bonds form between ?

B) the oxygen atoms in different water molecules

C) the oxygen atom in one molecule and the hydrogen atom in another water molecule

D) the hydrogen molecules in a single water molecule

F) Option 3

Pls help will give 14 points for this and brainlist

Answers

The answer to this question is B

The correct answer is option c): the oxygen atom in one molecule and the hydrogen atom in another water molecule.

Intermolecular forces or bonds are those interactions that hold molecules together. These are electrostatic forces.

Van der Waals forces are weak attractions that hold electrically neutral molecules together. At some point these molecules present an induced dipole, that is, the molecule acquires a partially positive and a partially negative charge momentarily, causing them to attract each other.

There are Van de Waals forces: Dipole - Dipole Forces, London Forces, Ion - Dipole Forces.

The dipole-dipole forces are forces of attraction between polar molecules. These molecules attract when the positive end of one of them is close to the negative of the other.

Hydrogen bonds are a type of dipole-dipole force. In this interaction, a molecule that presents hydrogen interacts with another that presents an atom with high electronegativity, such as oxygen, fluorine or nitrogen (O, F, N).

In this way, between the hydrogen, which has a low electronegativity and the electronegative atom, an interaction is established, due to their opposite charges.

Each water molecule has three atoms, two hydrogen and one oxygen.

In this case, between the different water molecules, the hydrogen bond is formed as follows: Oxygen is very electronegative, that is, it attracts the electrons of the bond with much more force than hydrogen.

As a consequence of this, oxygen is negatively charged and hydrogen positively, and a dipole moment is created. In this way, the water molecules clump together with each other.

In summary, the hydrogen in one water molecule is attracted to the oxygen atom in another water molecule.

So, the correct answer is option c): the oxygen atom in one molecule and the hydrogen atom in another water molecule.

Which idea did Lamarck propose that was rejected by his fellow scientists?

Answers

can i have brainest? please? anways hope i helped

Answer:

The correct answer will be acquired traits can be passed to offspring.

Explanation:

Lamarck is known for his idea of "inheritance of acquired traits" by studying neck size of giraffes and stated that:

1. New organs or traits can be produced by long use during lifetime as response to external environment,

2. characteristic is inherited to the next or succeeding generations.

3. Organ can disappear if not used.

Scientists were not able to find and explain evidence for the theory for example :

1. The blacksmith’s arm- enlarges when used continuously against external resistance like weight of the hammer but it is not necessary that the smith’s children at birth would have large arms or later in his life.

2. Skilled Hands of a musician- skillful hands of a musician causes no increase in the size of the fingers and this trait might be passed to musician’s children and they also play instrument skillfully with no practice.

Thus, acquired traits can be passed to offspring  is the correct answer.

*Please Help* Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation?


A. Invertebrates are more abundant than mammals in an ecosystem.

B. Mammals maintain their body temperature; invertebrates don't.

C. Most mammals are secondary consumers. Most invertebrates are primary consumers.

D. Invertebrates have smaller bodies than mammals.

Answers

Answer:

C. Most mammals are secondary consumers. Most invertebrates are primary consumers.

Explanation:

Net production efficiency (NPE) refers to how efficient an organism at one trophic level utilizes and transfers energy to the next trophic level. Ceetain organisms called CONSUMERS obtain energy by feeding on other organisms. They use this energy for their metabolic activities and transfer the rest when eaten or fed on.

As the trophic level increases, the net production efficiency decreases. This is because organisms at the lower level use energy less than those at higher trophic levels. In this question, invertebrates are mostly PRIMARY CONSUMERS (lower trophic level) while mammals are mostly SECONDARY CONSUMERS (higher trophic level). Therefore, invertebrates use energy more efficiently (less) than mammals, making them have a HIGHER net production efficiency than mammals.
