How are atoms in molecules being rearranged into different molecules
We are talking about chemical reaction here. In a chemical reaction, substances that react are called reactants, and substances which are formed are called products. Atoms in the reactants break their bond, rearrange themselves and form new bonds to make the product. So no atoms are added or removed, which is called law of conservation of atoms/mass.
The rearrangement of atoms in molecules into different molecules occurs through chemical reactions, where bonds are broken and formed so that atoms achieve a stable electron configuration. Thus, atoms are not destroyed but simply rearranged into different molecular structures. An example given was the formation of a water molecule.
Explanation:The rearrangement of atoms in molecules into different molecules involves breaking and forming of chemical bonds. This process is driven by chemical reactions, where atoms exchange, accept or donate electrons to achieve stable electron configurations, often in line with the octet rule. This involves the outermost shell of an atom, which is most stable when filled with electrons. As an example, let's take a water molecule (H2O), which consists of two hydrogen atoms and one oxygen atom. In an exchange reaction, the atoms in the reactants break their existing bonds and form new ones, effectively rearranging into a new molecule.
During a chemical change, it's important to note that atoms are neither created nor destroyed, but are merely rearranged into different substances. The substances that participate at the beginning of a reaction are called reactants, and those that result from the reaction are called products.
Therefore, chemical reactions involve the reassembly of atoms into different molecular structures, which is facilitated by the breaking and forming of bonds according to atomic stability and the electron configuration.

Answer:
sex linked trait
Haemophilia Trait that is linked to X chromosomeA trait like color-blindness, which affect many more men than womenThese are not equally likely to occur in male and femaleMendelian trait
A trait like eye colour or height These are equally likely to occur in male and femaleInvolves a dominant and recessive allelePredisposition to some diseases, like diabetes and heart diseasesExplanation:
Sex linked trait are those traits whose inheritance is based on the sex of individuals. The genes are usually located on the sex determining chromosomes as opposed to non-sex determining chromosomes or autosomes.
The frequency of occurrence of sex linked trait is more in a particular sex than the other. For example, baldness is more often found in men than in women, hence, baldness can be said to be sex linked. Other examples include hemophlia, color-blindness, etc.
Mendelian trait on the other hand are traits whose genes are located on autosomes. They inheritance usually follow simple dominance/recessive style and are equally likely to occur in male and female. Examples include hair colour, height, and diseases such as diabetes, etc.

Where does the endocrine system release hormones into? Apex
A) The stomach
B) The bloodstream
C) The mouth
D) The pancreas
Answer:
B) The bloodstream
Explanation:
The endocrine system releases hormones into the bloodstream. Option B is correct.
The endocrine system is a collection of glands that produce hormones, which are chemical messengers that travel through the bloodstream to target cells in other parts of the body. The endocrine system releases hormones directly into the bloodstream, where they can be carried to all parts of the body. The stomach, mouth, and pancreas are all organs that are part of the digestive system, but they do not release hormones.
Endocrine glands are glands that produce hormones, which are chemical messengers that travel through the bloodstream to target cells in other parts of the body. The stomach, mouth, and pancreas are exocrine glands, which means they produce substances that are released into ducts that lead to the outside of the body. Option B is correct.

what is the metric unit for measuring length?
Meters are correct you have centi, milli, kilo
The metric unit for measuring length is the meter, defined as the distance light travels in 1/299,792,458 of a second in a vacuum. For larger or smaller lengths, multiples or fractions of the meter (such as kilometers, centimeters, or millimeters) are used.
Explanation:The metric unit for measuring length is the meter (m). This was initially defined as 1/10,000,000 of the distance from the North Pole to the equator but has been updated for precision. Nowadays, it is defined as the distance light in a vacuum travels in precisely 1/299,792,458 of a second.
Regardless of the length being measured, the metric system uses the meter as the base unit. To accommodate different magnitudes of length, we use multiples or fractions of the meter. For very long distances, we use kilometers (1 km = 1000 m = 10³m), while for shorter distances, we use centimeters (1 cm = 0.01 m = 10⁻² m) or millimeters (1 mm = 0.001 m = 10⁻³ m).

what does traits will only be expressed if both recessive allies are passed down from each parent otherwise I'll be hidden in dominant allele what does that mean
Recessive Inheritance
When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait. One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin. Let (S) represent the dominant allele, and (s) represent the recessive allele. Only (ss) individuals will express a smooth chin. To determine the probability of inheritance of a smooth chin (or any other recessive trait), the genotypes of the parents must be considered. If one parent is heterozygous (Ss) and the other is homozygous recessive (ss), then half of their offspring will have a smooth chin. In other words, any of the offspring will have a fifty percent chance of having a smooth chin. A Punnett square can be used to determine all possible genotypic combinations in the parents.

as a cell becomes larger what happens to its surface area and volume
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
As a cell becomes larger, its volume increases faster than its surface area. This difference in growth rate can limit the cell's size, as the surface area might not be able to meet the metabolic demands of the increased volume.
Explanation:As a cell becomes larger, its volume increases at a significantly higher rate compared to its surface area. This phenomenon is due to the mathematical principles of scaling. Essentially, volume, which is spatial and involves three dimensions (length, width, and height), increases exponentially (by the power of 3) whereas surface area, which only incorporates two dimensions (length and width), increases quadratically (by the power of 2).
This difference in growth rates could lead to a problem. When a cell's size increases, its metabolic demand also grows. Metabolic demands are met by the materials that enter the cell from its surface area (like oxygen and nutrients). So, if a cell becomes too large, the surface area might not be sufficient to support the increased volume, thereby limiting the cell's size.
