Why are skin cells not the same as muscle cells?

Answers

Answer 1

Explanation:

Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement.

What is the correct chronological order of the 3 steps of translation from mRNA to a polypeptide?

Answers

The translation of an mRNA molecule by the ribosome into a protein occurs in three stages: initiation, elongation, and termination.

The process by which a cell manufactures proteins using genetic information supplied by messenger RNA in biology. mRNA is produced as a result of DNA replication, and the information it carries guides the cell on how to link amino acids together to generate proteins.

After the process of transcription of DNA to RNA in the cell's nucleus, ribosomes in the cytoplasm or endoplasmic reticulum create proteins. Transcription is the process of transcribing DNA to RNA, while translation is the process of utilizing RNA to make proteins. DNA secures and stabilizes genetic material in the nucleus of cells as a reference, or template.

How many gene pairs are in the human genome?

Answers

The genome is organized into 22 paired chromosomes, termed autosomes, plus the 23rd pair of sex chromosomes (XX) in the female and (XY) in the male.

The human genome is a complete set of nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome.

Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA, transfer RNA, ribozymes, small nuclear RNAs, and several types of regulatory RNAs.

d) all of above

Answers

The correct answer is option D all of the above.

Biodiversity refers to all the life forms that exist in an area including plants, animals, and humans. It is important to preserve biodiversity because man is dependent on nature for food, shelter, fuel, and everything.

Biodiversity can be preserved by:

a) By preventing deforestation - Trees are home to a large number of birds and animals. Trees help in maintaining the balance in the ecosystem.

b) By protecting species - In nature each specie has a specific role and is interconnected to other species. Protecting the species is the most important aspect of the preservation of biodiversity.

c) By reducing waste - Reducing the waste will create a cleaner and safer environment for all organisms to thrive in thus protecting biodiversity.

What is point mutation and its types?

Answers

A genetic modification caused by the substitution of a single nucleotide for another nucleotide is called point mutation. Transition mutations and transversion mutations are two types of point mutations.

Point mutations are gene mutations that occur when a single nucleotide base in an organism's genome is changed, inserted, or deleted. Point mutations have a variety of effects on downstream protein product, with moderately predictable consequences based on mutation-specific features. In terms of protein production, composition and function, these consequences can range from no effect (e.g., synonymous mutations) to negative effects (e.g., frameshift mutations).

Conversion occurs when one purine moiety is replaced by another purine or one pyrimidine is replaced by another pyrimidine. The conversion occurs when the purine is replaced by pyrimidine or vice versa. The wrong mutation leads to the creation of a different amino acid. Missile mutations, also known as nonsynonymous alterations, alter one codon to produce another protein. The term point mutation is sometimes used to describe the addition or deletion of a base pair.

Answers

The difference that is hypothesized to explain the observation that social monogamy is rare in mammals but common in birds is the need for biparental care.

Social monogamy refers to a social and sexual relationship between two individuals of the same species in which both individuals contribute to the care of their offspring.

In many species of mammals, males typically do not contribute significantly to the care of their offspring, and females are responsible for providing all of the necessary care. This is because the energy demands of pregnancy and lactation are high, and females need to devote a significant amount of time and resources to caring for their young. In contrast, many species of birds have a more equal division of labor between the sexes, with both males and females contributing to the care of their offspring.

This is often because the energy demands of producing eggs are lower than those of producing offspring in mammals, and because birds can often forage for food while leaving their young in the nest.

please describe the signal transmission across a myoneural junction that allows the nervous system to move the muscles of a football player during a game? please be detailed with your description

Answers

The signal transmission across a myoneural junction, also known as the neuromuscular junction, is the process by which the nervous system communicates with the muscles to produce movement.

This process is essential for the normal function of the musculoskeletal system and allows us to perform a wide range of movements, including those required to play a football game.

Here is a detailed description of the signal transmission across a myoneural junction:

An action potential, or electrical impulse, travels down the axon of a motor neuron (a type of nerve cell) until it reaches the myoneural junction.At the myoneural junction, the axon terminal of the motor neuron releases a chemical called acetylcholine (ACh) into the synapse, or the small gap between the axon terminal and the muscle fiber.ACh binds to receptors on the surface of the muscle fiber, causing an electrical current to flow across the muscle cell membrane.This electrical current triggers the release of calcium ions from internal stores in the muscle fiber, which leads to a contraction of the muscle.After the signal has been transmitted, the ACh is broken down by an enzyme called acetylcholinesterase (AChE). This prevents the signal from being transmitted continuously, which would lead to sustained muscle contraction.

This process occurs very quickly and allows the nervous system to rapidly communicate with the muscles to produce movement. It is essential for the coordination of movements and the execution of fine motor skills, such as those required to play football.
