Answer:
A. Having differences
Explanation:
as opposed to homogeneous which is the same or having similarities
Answer:
The best answer is A - having differences.
Explanation:
When comparing heterogeneous and homogeneous, a helpful trick to remembering the difference is to look at the root of each word. Homo- means “same”, and hetero- means “different”.
Heterogeneous can be used to describe any group of something that is mixed and varied in composition (i.e. a box of Legos).
Homogeneous can be used to describe any group of something that is the same composition throughout (i.e. sweet tea).

The __________ , on the posterior thorax, are roughly triangular in shape. They have no direct attachment to the axial skeleton but are held in place by trunk muscles.
The scapulae, on the posterior thorax, are roughly triangular in shape. They have no attachment to the axial skeleton but are held in place by trunk muscles.
The bone that connects the clavicle (the collar bone) with the humerus (the upper arm bone) is the scapula (in plural, scapulae), or shoulder blades. The word 'scapular' originates from a Latin word meaning 'trowel' or 'shovel', because of its resemblance to a shovel.
The scapula is a triangular shaped bone that can be found posterior (at the back) to the thorax. Although they are not attached directly to the axial skeleton, they are necessary for the smooth motion of the upper extremity and several other motions associated with daily living, for example, shrugging of the shoulders. The pectoral girdle and chest muscles assist with the protraction and retraction and retraction of the scapula. It is also essential to the stability of the shoulder point as a whole.

Formation of vinegar take place due to the action of
When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the magnitude of the work done by the electric field of the membrane?.
The magnitude of the work done by the electric field of the membrane is W = 1.28 × 10⁻²⁰ Joules.
We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.
As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.
The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,
q = 1.6 × 10⁻¹⁹ Coulombs
Then the Work would be:
W = Vq
Here,
v = Potential difference
q = Charge
The 80mV potential difference we will have is quantified as follows:
W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)
W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

What two separate diseases are the main copd diseases? give background on each disease.
Answer:
Emphysema and chronic bronchitis are the two most common conditions that contribute to COPD
Explanation:
Breathlessness is a symptom of the lung disease emphysema. Alveoli, also known as the lungs' air sacs, suffer damage in those suffering from emphysema. These air sacs' internal walls weaken & burst with time, resulting in the formation of bigger air voids rather than numerous, tiny ones.
Emphysema symptoms could include the coughing, sneezing, breathlessness, tightness in the chest, as well as a higher production of mucus. Usually, symptoms may not appear till the tissue of lungs has just been damaged to 50% or above.
A severe cough that lasts longer than three months and persists for minimum two years in a row qualifies as chronic bronchitis. There may be times when the cough and perhaps other signs of chronic bronchitis get worse.

Twisted: The mutant allele is neither totally dominant nor completely recessive to its corresponding wild-type allele.Pale: Neither the mutant allele nor its corresponding wild type allele is dominant or recessive.Is an allele dominant or recessive?An allele cannot be "dominant" or "recessive" by definition. These phrases instead describe the interaction between two alleles. A heterozygote is used to assess this relationship since it has one dominant allele and one recessive allele, with the dominant allele determining the phenotype of the heterozygote.The phenotypes of some heterozygotes fall somewhere between those of the two homozygotes. Because neither allele is totally dominant over the other, this scenario is the result of partial dominance.How does genetic analysis work?the examination of a DNA sample to search for mutations (changes) that could impact a person's susceptibility to a disease or how they respond to therapy.What techniques are used in genetic analysis?Cytogenetic testing, biochemical testing, and molecular testing are the three main types of genetic testing that can be used to identify anomalies in DNA sequence, protein function, and chromosome structure, respectively.

Explanation:
eheeyehehheh3bbed
Carbon from glucose is used in the process of anaerobic respiration as both an electron donor and an electron acceptor. Without oxygen present, this mechanism uses glucose as its primary energy source.
What happens in the anaerobic respiration ?During anaerobic respiration, glucose is converted to pyruvate, which is subsequently transformed into ethanol and carbon dioxide, among other compounds. As part of this procedure, glucose provides electrons to NAD+, which uses them to convert pyruvate into ethanol and carbon dioxide.
NAD+ then accepts the electrons, becoming NADH. Carbon from glucose is also used in aerobic respiration as an electron donor and an electron acceptor. But for that to happen, oxygen is needed. This procedure results in the conversion of glucose into pyruvate, which is subsequently further broken down into water and carbon dioxide.
In this procedure, glucose provides electrons to NAD+, which uses them to convert pyruvate into carbon dioxide and water. NAD+ then accepts the electrons, becoming NADH. Carbon from glucose is used in fermentation as both an electron donor and an electron acceptor. It doesn't need oxygen to happen, though.

Which statements accurately describe osmosis? Check all that apply.
The first, fourth, and fifth statements accurately describe osmosis.
The net movement of solvent molecules through a semipermeable membrane is known as osmosis. Since the movement is downward and goes from greater to lower concentration, it is comparable to diffusion. However, in osmosis, the movement must take place through a membrane that is semipermeable or selectively permeable. It cannot be referred to as osmosis without this component.
Osmosis is about the net movement of the solvent molecules (not the solute), whereas diffusion is frequently depicted as the net movement of solutes between two solutions (solvent such as water molecules). The water must migrate in order to equalise the concentrations of the two areas due to the different concentrations of water molecules on the two sides of the membrane.
