Solids have a high density because the particles are very close together, a liquid mass is slightly less dense, and a gas mass has a very low density with the particles much further apart.

The measure of how densely a material is packed together is called density. As the mass per unit volume, it has that definition. Density Formula: D or Density Symbol: D ρ = m/V where the object's mass (m), its volume (V), and its density () are all given.

Generally, gases are less dense than liquids, while liquids are less dense than solids. This is due to the fact that solids have tightly packed particles, liquids have materials in which particles can slide around, and gases have free-moving particles.

Therefore, Gasses are less dense than solids because particles are far away from each other in gas masses.

Explanation:

These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.

Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).

Explanation:

The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

During translation, the ribosome reads the mRNA and uses the information to assemble a protein.

Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.

Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.

The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

Answer:

Explanation:

1     Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA.Chemicals might induce DNA mutations, such as polycyclic hydrocarbons (fumes found in oil stations, or smoke from a tobacco cigarette), intercalating agents such as Ethidium Bromide (carcinogen), but also radiations such as UV-radiation (C and T bases are most vulnerable and would bind to identical bases unstead of their

2    Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.) As the fertilized egg divides, each resulting cell in the growing embryo will have the mutation. De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.

Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not. Depending on the mutation and how many cells are affected, mosaicism may or may not cause health problems.

Answer:

Independent variable: LENGTH OF EXPOSURE TO DIRECT SUNLIGHT

Dependent variable: PRODUCTION OF FLOWERS

Control group: THE GROUP OF PLANT THAT WASN'T EXPOSED TO SUNLIGHT i.e. 0 hours

Experimental group: THE GROUP OF PLANTS THAT WERE EXPOSED TO SUNLIGHT

Constant: THE SAME PLANT SPECIES

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the experimenter exposes the specific plant species to sunlight at different length of time, hence, the LENGTH OF EXPOSURE TO DIRECT SUNLIGHT is the independent variable.

Dependent variable is the variable which is measured in an experiment. In this experiment, the measured/dependent variable is the PRODUCTION RATE OF FLOWERS by the plant species.

Control group is the group in an experiment that does not receive the variable being tested. In this experience, the control group is THE GROUP OF PLANT THAT WASN'T EXPOSED TO SUNLIGHT i.e. 0 hours

Experimental group is the group of am experiment that is exposed to the experimental treatment (sunlight). In this case, the experimental group is THE GROUP OF PLANTS THAT WERE EXPOSED TO SUNLIGHT.

Constants are variables of an experiment that must be kept unchanged for all groups throughout the experiment in order not to affect the experiment's outcome. In this experiment, the constant is THE SAME PLANT SPECIES used,

Answer:

This reaction is endothermic, therefore the energy uptake will be the main pillar of metabolism, in addition, the phosphorylation energy will always be used for the cell, on the other hand, in the case of phosphorylation, reverse effects will be seen, and this is when a I play an enzyme called kinase.

On the other hand, the intake or capture of energy in the form of energy currency is understood as the medium GIVES energy to the cell, it captures it and is not exothermically released in the form of heat.

Explanation:

These processes happen because of it at postpondrial moments, where the insulin hormone is high and it is sought to phosphorylate glucose to retain it inside the cell so that it does not dissipate exothermically.

This is the mechanism by which the human generates energy reserves of complex carbohydrates such as glycogen.

Answer:

Electrons are much smaller in mass

Explanation:

Although similar in mass, protons are positively charged, while neutrons have no charge. Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Electrons are much smaller in mass than protons, weighing only 9.11 × 10−28 grams, or about 1/1800 of an atomic mass unit.

Explanation:

Answer:

Proteins interact with DNA through electrostatic interactions (salt bridges), dipolar interactions (hydrogen bonding, H-bonds), entropic effects (hydrophobic interactions) and dispersion forces (base stacking). These forces contribute in varying degrees to proteins binding in a sequence-specific or non–sequence-specific manner.
