what property of rna enables some rna molecules to function as enzymes?
Answer:
Property 1. Some bases in RNA have functional groups.
Property 2. it has a 3-D structure because it has the ability to base pair with itself.
Property 3. RNA can hydrogen bond with other nucleic acid molecules.
RNA can act as an enzyme which is known as Ribozyme because of the presence of some properties such as the ability to form base pair with itself, presence of functional groups, etc.
What are Ribozymes?The ribozymes are the catalytic RNA molecules, which were first identified in the early 1980s. They show the intrinsic property of breaking and forming covalent bonds in the RNA molecules. In many ways, ribozymes can be compared to the protein enzymes which can catalyze the cleavage of peptide bonds in different proteins or peptide molecules.
The term ribozyme refers to the enzymatic activity of RNA and the ribonucleic acid nature of RNA at the same time. They can catalyze the formation of polypeptide molecules by decreasing the activation entropy of the reaction.

Suppose a father of blood type A and a mother of blood type B have a child of type O. Is this possible? If they have more children, what could their blood types be?
Answer:
no it can't be possible (but it depends if the fathers blood group is AA not AO and the mother's group is BB not BO) otherwise it can't be possible
Explanation:
blood group O is recessive so both parents must have this type of blood group or at least one of them to have an offspring with this blood group
if they had more children they'd have blood groups A,B or AB
If you know that a DNA double helix consists of 20 % adenine, what percentage of the DNA double helix is guanine (G)
Answer:
80%
Explanation:
As per rules the percentage of adenine is equal to thymine and C is equal to G. If A is 20 then the value of T is 20 too and along with that C and G are equal. The value of G is 30%.
What type of bonding is present between adenine and thymine ?Hydrogen bonding is present between the bases where the two hydrogen bonds are present in between A and T. C and G are binding together by three hydrogen bonds.
Adenine is 20% that means thymine is equal to 20% as well where the remaining percentage out from 100 % is 60% where the value if cytosine and guanine are equal and the percentage they have is 30% and 30% that is guanine is 30%.
DNA always in the structure has adenine residues equal to thymine residues and cytosine residues equal to guanine residues thus the value of their composition in the structure can be predicted by this.

Answer:
Plants. Like other Mediterranean-type ecosystems, the California Floristic Province is distinguished more by the endemism of its plants than its animals.

Which statement explains the function of a lysosome?
Answer: break down lipids, carbohydrates, and proteins into small molecules
Explanation:
Lysosomes help in the removal of waste material from the cell.
What are lysosomes?
An organelle of a cell that is membrane-bound and houses digestive enzymes is called a lysosome. Numerous cell functions include lysosomes. They disassemble extra or worn-out cell components. They might be utilized to eliminate invasive bacteria and viruses. Lysosomes can assist a cell in self-destruction in a process known as programmed cell death, or apoptosis, if the damage is irreparable.
Particularly acidic organelles include lysosomes. Therefore, it must be shielded from the remainder of the cell's interior. This means that the digestive enzymes are stored in a compartment with a membrane surrounding them since they need to be in an acidic, low-pH environment.
These enzymes, known as hydrolytic enzymes, convert big molecules into smaller ones. For instance, huge proteins can be broken down into amino acids, large carbs can be turned into simple sugars, and large lipids may be reduced to single fatty acids. And whenever they do that, the remaining parts of the cell receive the nutrients they require to.
Therefore, if you are unable to accomplish that, it will not be able to convert huge molecules into smaller ones. These big molecules will be stored by you, and this is an illness. Another variety of lysosome storage disorders prevents the little molecules created by the big molecules from leaving the lysosome.
Therefore, lysosomes help in the removal of waste materials from the cell.

what three conditions are necessary for natural selection to occur
For the natural selection to occur, the basic rule is that species that fit the best are selected by nature to exist in the nature. The 3 conditions that are required by nature for natural selection to occur are :
1. Struggle for existence
2. Variation
3. Inheritance
What is natural selection ?The offspring that is fit for the nature following the adaptation to the variation and inheritance crossing the struggle for existence to occur in nature tends to be selected by the nature to exist and produce more offspring.
The organisms that are adapted to the nature following the mutations and variations that are required for the better adaptations live more than the species which has lesser adaptation. These species produce more offspring.

Areas of the body with a high degree of sensory acuity (very sensitive) have SMALL receptor fields. It determines how accurately a stimulus can be located.
Sensory acuity indicates how accurately a given stimulus is located.
Sensory acuity depends on two major factors: the density of sensory receptors, and the size of receptive (neuronal) fields.
These receptors can respond to different stimuli such as, among others, temperature factors (i.e., thermoreceptor), chemical factors (i.e., chemoreceptor), pressure factors (i.e., mechanoreceptor), etc.
