Deme species are a group of organisms that interbreed among themselves to form offspring

Explanation:

Deme-Species are a group of organisms that have similar genes and have the ability to produce fertile offspring. The process of formation is called speciation; it mainly occurs due to Natural selection.A demi species have the same genepool and have ability to interbreed among themselves.population is usually made of several demes that can be partially isolated from each other.A geographical barrier may limits gene flow between demes, but not sufficiently to result in speciation. In rare cases genepool or deme species can result in speciation.

The type of evidence is fossil evidence.

Fossil evidence is the type of evidence that a scientist finds fossilised bones of a huge animal that doesn't exist today. Fossils are the preserved remains or traces of ancient life, and they provide important evidence about the history of life on Earth.

The bones of a huge animal, which are fossilised, provide an idea of the animal that once existed. By studying the fossilised bones of extinct animals, scientists can determine what the animals looked like, how they lived, and how they evolved over time. Fossils can also provide information about the environment in which the animal lived.The study of fossils is called paleontology, and paleontologists use a variety of techniques to study fossils, including x-ray, scanning electron microscopy, and isotopic analysis. By studying fossils, scientists can learn about the evolution of life on Earth and gain insight into the past environments in which organisms lived.

The hypothesis about the dwarf planet Pluto is falsifiable. This means that the hypothesis can be tested through experiments or observations to determine whether it is true or false.

The hypothesis that Pluto is made of ice, can be tested by observing the planet's surface and analyzing its composition. If the results show that Pluto is not made of ice, then the hypothesis is proven false.
On the other hand, a non-falsifiable hypothesis is one that cannot be tested or proven false. For example, if the hypothesis is that Pluto is the most beautiful planet in the solar system, this cannot be tested or proven false because beauty is a subjective concept and cannot be measured objectively.

Explanation:

The major blood vessels that are connected to the heart include the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs, where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart) and the coronary arteries (which supply blood to the heart muscle).

Inheritance of recessive traits involving multiple alleles follows the same principles as with two alleles. However, with multiple alleles, there can be a greater variety of phenotypic expressions.

In a population with multiple alleles for a gene, each individual will have two copies of the gene. The expression of the trait will be determined by the combination of the two alleles an individual inherits. If an individual receives two copies of the recessive allele, they will express the recessive trait. However, if an individual inherits two different alleles, the dominant allele will be expressed, and the recessive allele will be masked. For example, in the ABO blood group system, there are three alleles: O is recessive, while A and B are codominant. An individual can have AA, BB, AB, AO, BO, or OO genotypes. The presence of the O allele results in the O blood group phenotype.

Explanation:

RNA molecules fold into complex 3-D structures when base pairing occurs between nitrogen base pairs. The bonds forned are hydrogen bonds.

RNA molecules refers to nucleic acids which are built from ribose sugar molecules instead of deoxyribose as in DNA molecules.

RNA molecules as in DNA are composed of a sugar backbone, a nitrogenous base, and phosphodiester linkages.

The nucleotides found in RNA molecules are:

RNA is able to form complex 3-D structures even though they are single-stranded because of base pairing that occurs between adenine and uracil, and guanine to cytosine.

The bonds present in thebase pairs are hydogen bonds.

Hydrogen bonds are bonds which are formed between hydrogen and a highly electronegative atom such oxygen, nitrogen, chlorine, and fluorine.

In the RNA molecule, hydrogen bonds form betweenthe oxygen and nitrogen atoms of the either uracil, adenine, cytosine, or uracil.

These hydrogen bonds results in three-dimensional structures of RNA.

In conclusion, RNA molecules are single-stranded nucleic acids materials.

In this passage, I'm kinda sure that places a strain means pressure.

Explanation:

The answer is mitochondria because this is the super producer of cell systems. while an active animal, (squirrel, rodents, horses, deer etc.) are all prey items for preditors, they possess more energy to survive & escape danger...

A muscle cell requires more energy than any other cell and that is why a muscle cell has more mitochondria than any other cell. So the correct option is D.

Mitochondria, very commonly known as the powerhouses of the cell are the organelles of the cell responsible for the production of energy in the form of ATP. ATP is the biologically useful form of energy produced from the food we eat.

The food is broken down into nutrients in the digestive system. When they ready all the cells, they are broken down, first in the cytoplasm (glycolysis) and then in the mitochondria. In the mitochondria, ATP is produced.

Mitochondria are present in almost all types of human cells. Their function is of extreme importance for our survival. Mitochondria perform other functions than energy production. They are cell signalling, apoptosis etc.

Thus since muscle cells require more mitochondria, they have more mitochondria than any other cell.

Therefore the correct option is D.

True: DNA polymerase III does not dissociate from the DNA template strand after it has catalyzed the joining of two adjacent nucleotides, so it is described as an enzyme.

What is DNA polymerase III? DNA polymerase III is an enzyme that assists in the replication of DNA. It is a component of the replisome, a set of proteins that work together to copy DNA. DNA polymerase III has a proofreading feature, which means it can detect and correct errors that occur during DNA replication. It also plays a critical role in the elongation of new DNA strands. DNA polymerase III has a high processivity, which means it can catalyze the joining of numerous nucleotides before detaching from the DNA template strand. DNA polymerase III is an enzyme that remains connected to the DNA template strand until replication is complete.

Explanation:

DNA is the chemical name for the molecule that carries genetic instructions in all living things.

Answer and explanation:

Chromosomal multiplicity, also known as polyploidy, is the name given to the cell or organism that has a numerical change in its whole set of chromosomes (for example, a triploid organism of a diploid species is a polyploid because it has an extra set of chromosomes than the rest of its species). Most species are diploids, but polyploidy is quite common in plants.

In agriculture, polyploidy can be beneficial by giving the plants better chances of survival and/or providing more desirable traits. Crop species such as bread wheat and triticale (a wheat and rye hybrid), for example, have 6 sets of chromosomes. Quinoa, coconut, and peanut are tetraploids (4 sets of chromosomes). Many of these cases of polyploidy in plants of importance for the agriculture field are a result of hybridization (which occurs when two different species are crossed in order to produce offspring with a combination of characteristics of the two-parent species).

Answer: no known treatments

Explanation:

Organic substances are moved by plants from sources to sinks. Organic molecules are loaded into phloem sieve tubes at the source by active transport. Vascular flowering plants belong to the class Angiospermophyta.

Osmosis causes water to be taken up by the phloem at the source when there are high solute concentrations there. Explain how vascular plants move organic chemicals. Water can be transported through gradients of hydrostatic pressure because it is incompressible.

Phloem transfers organic molecules through sieve tubes and sieve plates from the place of production to the place of usage.

The photosynthetic bacterium consumed by the predatory cell that evolved into an organelle is called chloroplast.

The process of endosymbiosis led to the incorporation of a photosynthetic bacterium into a larger eukaryotic cell, giving rise to the chloroplast organelle found in plants and algae. The bacterium evolved into a specialized organelle that performs photosynthesis, using light energy to synthesize organic compounds. The chloroplast has its own DNA and ribosomes, which are similar to those found in bacterial cells, providing evidence for the endosymbiotic origin of the organelle. The chloroplast is also surrounded by a double membrane, which is thought to represent the remnants of the ancestral bacterial cell wall. Overall, the evolution of the chloroplast through endosymbiosis has played a critical role in the development of photosynthetic organisms and the ecosystems they support.
