Answer:

Ribosomes located in the cytoplasm

Explanation:

Translation is the second process involved in protein synthesis. It is the process whereby protein is synthesized from an mRNA molecule. Initially, the information contained in the DNA molecule is transcribed into RNA molecule in the nucleus of eukaryotic cells.

The mRNA molecule then leaves the nucleus and attaches to a complex of RNA and protein called RIBOSOME, which is found floating freely in the cytoplasm or attached to Endoplasmic Reticulum. The Ribosome is an organnelle regarded to be the site of protein synthesis.

Hence, translation starts when the mRNA molecule attaches to the Ribosome in the cytosol of the cell.

A cell's cytoplasm is where translation takes place, specifically on ribosomes. Cellular organelles called ribosomes are in charge of protein production. In eukaryotic cells, they can be found either free in the cytoplasm or bound to the endoplasmic reticulum (ER).

The messenger RNA (mRNA) molecules that carry the genetic code from DNA are read by the ribosomes during translation to create proteins. The procedure entails translating the mRNA sequence into a certain amino acid sequence, which creates the basic framework of a protein.

Codons are collections of three nucleotides that the ribosomes use to read the mRNA. Each codon is associated with either a particular amino acid or a stop signal.

Clonus often accompanies a hyperactive reflex after damage has occurred to the brain. Hyperactive reflexes are a common sign of upper motor neuron dysfunction. Clonus is a rhythmic, involuntary contraction and relaxation of a muscle in response to a sustained stretch stimulus.

It is often seen in patients with neurological disorders such as multiple sclerosis, cerebral palsy, and spinal cord injury. Clonus can be a sign of spasticity, which is a state of increased muscle tone and resistance to passive movement. In some cases, clonus can lead to muscle fatigue, pain, and impaired function. Therefore, it is important to diagnose and treat the underlying cause of clonus to prevent further damage and improve quality of life for the patient.

The correct structure of a DNA molecule is as follows two strands of DNA are joined by nitrogenous bases. Here option D is the correct answer.

The structure of a DNA molecule is best described as two strands of DNA joined by nitrogenous bases. DNA, or deoxyribonucleic acid, is a double-stranded molecule that carries genetic information in living organisms. Each strand of DNA is made up of a series of nucleotides.

A nucleotide consists of three components: a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). The two strands of DNA are connected by hydrogen bonds between the nitrogenous bases.

The structure of DNA is often referred to as a double helix. The two strands of DNA run in opposite directions, with one strand running in a 5' to 3' direction and the other running in a 3' to 5' direction. The nitrogenous bases in the strands form complementary base pairs, with adenine always pairing with thymine (A-T) and cytosine always pairing with guanine (C-G). Therefore option D is the correct answer.

To get from equation I to equation II, all coefficients in equation I should be divided by 2. A method to determine if an equation is written in the correct way is to ensure that the number of atoms of each element is the same on both sides of the equation, and that the equation is balanced.

b. To get from equation I to equation II, you would need to divide all coefficients in equation I by 2.

c. Yes, you can divide equation II by another factor and still have it be correct, as long as you divide all coefficients in the equation by the same factor. This is because the coefficients in a balanced chemical equation represent the relative numbers of each molecule or atom involved in the reaction, so dividing them all by the same factor will preserve the same ratios between the different components.

d. One method to determine if an equation is written in the correct way is to ensure that the number of atoms of each element is the same on both sides of the equation. This can be done by counting the number of atoms of each element in each molecule or ion involved in the reaction and comparing them on both sides of the equation. Additionally, the equation should be balanced, meaning that the same number of each type of atom should appear on both sides of the equation.

Answer:

Out of the cell

Explanation:

Answer:

it has to be an idea that can be supported  through carefully crafted experimentation or observation.

The observation that the scientist collected young unbanded snails and kept them until they were fully grown and mated them, and the eggs laid produced 35 unbanded and 12 banded snails, can be explained through genetic inheritance.

Cepaea nemoralis snails have two alleles for banding, one dominant and one recessive. The dominant allele B is responsible for the banding pattern, while the recessive allele b is responsible for the unbanded pattern.

If the unbanded snails collected by the scientist were homozygous recessive (bb), then all of their offspring would also be unbanded (bb) since they only carry the recessive unbanded allele.

However, if the unbanded snails were heterozygous (Bb) for the banding gene, then they would carry both the dominant and recessive allele, and there is a 50% chance of each offspring inheriting the dominant banding allele.

Therefore, if we assume that the unbanded snails collected by the scientist were heterozygous (Bb), we can use a Punnett square to predict the possible offspring genotypes. The square would show that each parent has a 25% chance of producing offspring that are homozygous dominant (BB) and show a banded pattern, 50% chance of producing offspring that are heterozygous (Bb) and unbanded, and 25% chance of producing offspring that are homozygous recessive (bb) and unbanded.

Based on these predictions, the 35 unbanded and 12 banded snails observed in the offspring suggest that the unbanded snails collected by the scientist were indeed heterozygous (Bb).

This ratio also corresponds to the expected 3:1 ratio of dominant and recessive alleles in a monohybrid cross.

In conclusion, the observed figures can be explained by assuming the unbanded snails collected were heterozygous for the banding gene, and the resulting offspring followed the laws of genetic inheritance.

A material must be moved across a membrane using ATP during active transport, frequently with the aid of protein carriers and almost always against its concentration gradient. Active protein pumps are one of the most prevalent kinds of active transport.

The cell membrane is a biological membrane that separates and shields the interior of all cells from the external environment. It is also referred to as the plasma membrane (PM), cytoplasmic membrane, or plasmalemma (the extracellular space). A lipid bilayer makes up the cell membrane, which is composed of two layers of phospholipids with cholesterol (a lipid component) positioned between them to ensure proper membrane fluidity at varying temperatures.

Tapeworms are bilaterally symmetrical flatworms that belong to the phylum Platyhelminthes. They lack a true body cavity, also known as a coelom, which is a fluid-filled space between the gut and the body wall found in many animal phyla.

A coelom is a cavity within the body that is completely lined with mesoderm, a germ layer that gives rise to muscles and other internal organs. This cavity provides space for organs to move independently and facilitates their functioning. However, tapeworms, as well as other flatworms, lack a coelom and instead have a solid body. This limits their ability to move and restricts the complexity of their internal structures. Instead, they rely on diffusion to transport nutrients and gases between their cells and the external environment. Despite their simple body plan, tapeworms are successful parasites that can cause significant harm to their hosts if left untreated.

Answer:

Dimetrodon (/daɪˈmiːtrədɒn/ (About this soundlisten)[1] or /daɪˈmɛtrədɒn/,[2] meaning "two measures of teeth") is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma).[3][4][5] It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878.

Explanation:

Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than to modern reptiles, though it is not a direct ancestor of mammals.[4] Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally called "mammal-like reptiles".[4] This groups Dimetrodon together with mammals in a clade (evolutionary group) called Synapsida, while placing dinosaurs, reptiles and birds in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and mammals from most of the earliest sauropsids.

The statement "the start of the Cenozoic era marked the dawn of the age of mammals" can be explained by the fact that "the Cenozoic era saw the rise and dominance of mammals as the dominant group of animals on Earth".

The Cenozoic era is the current geological era, which began approximately 66 million years ago and continues to the present day. It is often referred to as the "Age of Mammals" because it is during this era that mammals experienced a significant diversification and became the dominant group of animals on Earth.

Several factors contributed to the rise of mammals during the Cenozoic era. One of the key factors was the extinction event that occurred at the end of the preceding era, the Mesozoic era, which wiped out the dinosaurs and opened up ecological niches for mammals to exploit. With the disappearance of large reptilian competitors, mammals had the opportunity to diversify and occupy a wide range of habitats.

Additionally, during the Cenozoic era, there were significant changes in the Earth's climate and geography, including the formation of new mountain ranges and the development of grasslands. These changes provided favorable conditions for mammals to adapt and evolve. Mammals developed various adaptations such as specialized teeth, limbs, and reproductive strategies, which allowed them to exploit different food sources and environments.
