Answer:
The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.

what is the new peptide chain when the new dna segment is translated for 3'- TACAGGGTGCTACCCACT-5'
Answer:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
Explanation:
Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.
In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the
mRNA sequence from this DNA during transcription will be:
AUG UCC CAC GAU GGG UGA
From this mRNA sequence, the peptide chain that will result following translation is:
Methionine- Serine- Histidine- Aspartate- Glycine- stop

Convection currents for weather start from when the Sun heats up the air. true or false
Answer:
True.
Explanation:
Convection currents for weather start from when the sun heats up the air because convection. Current is a form of heating where the lighter warm or less dense material rise above the denser or more dense material because the more dense materials cool and sinks downward giving rise to sea breeze. This convection current lead to circulation pattern on Earth
How do the functions of the skeletal and muscular system differ?
A.
Muscles send signals to the body, and bones are responsible for movement.
B.
Bones provide structure and support to the body, while muscles move the bones.
C.
Bones send signals to the body, and muscles are responsible for movement.
D.
Muscles provide structure and support to the body, while bones move the muscles.
Answer:
The functions of the skeletal and muscular systems differ in that bones provide structure and support to the body, while muscles move the bones.
Explanation:
The skeletal and muscular systems have complementary functions, which is why they are sometimes referred to as the musculoskeletal system.
Bones are solid organs, made up of calcium, which are connected to each other through joints, which provide them with a certain range of mobility. The main functions of the bones are protection and body support.
Muscles are contractile organs that are attached to bones by tendons. The location and relationship of the muscle to the bones is what makes it possible for the bony skeleton to move. Muscle contraction and relaxation is what contributes to the different body movements.
The other options are not correct because:
The function of the bone is to support, and the function of the muscle is to produce movement. Bones and muscles are not the ones that send the signals for body movement to occur.Answer:
B. Bones provide structure and support to the body, while muscles move the bones.

Describe the osmotic regulation strategies of marine fish
Answer:Water will diffuse into the fish, so it excretes a very hypotonic (dilute) urine to expel all the excess water. A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. It actively excretes salt out from the gills.
Explanation:
1. A plant tissue cells are elongated and thickened with cellulose strips at the corners.
a. Name the tissue having these features.
b. How is it involved in storing starch?
c. How does it help young stems and leaves to bend without breaking?
Answer:
Explanation:
Collenchyma is the tissue with cellulose strips at the corner. It is usually found in the shoots and leaves of plants providing strength, support. The cells have thick cell walls with the corners thickened with cellulose.
Collenchyma is made of up cellulose and pectin, starch are stored as cellulose in collenchyma.
It prevents breakage of young stem by given strength, especially in growing shoots and leaves due to its thickened corners.

is when the lead male and female are given preferential treatment to resources such as food and potential mates.
Answer:
Dominance hierarchy
Explanation:
Dominance hierarchy may be defined as a type of a social hierarchy which arises when the members of a social group interacts and create a ranking system in the society. The members compete for access to the to limited resources as well as mating opportunities.
It is the ranking system behavior in the nature where the lead or the main male and females are provided preferential treatment to the food resources and potential mates.

When a mitochondrial chaperone helps a mitochondrial matrix protein into the matrix by biased diffusion, the chaperone is said to be acting as ______.
a. Brownian motion
b. biased diffuser
c. Brownian ratchet
d. misratchet
e. unbiased diffuser
Answer:
c. Brownian ratchet
Explanation:
Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.
The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.
The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.

What type transporters are used by mitochondria to shuttle ATP and ADP through mitochondria and cell?
Answer:
The correct answer is ATP/ADP transporter.
Explanation:
Mitochondria are the cellular compositions, considered as the driving force of the cells. Each day, ATP is required by living beings to energize all of the cellular activities. Muscle contraction, nerve impulses, protein synthesis, and DNA replication are some of the important procedures, which depend upon ATP supply.
As the only small concentration of ATP is present within the body, there is a need to produce it from the expended product ADP and phosphate with the help of the complex of enzyme, known as ATP synthase situated within the mitochondria. For the ADP to reach the enzyme and for refueling of the cell by the product ATP, each molecule is required to pass through an impermeable lipid membrane, which envelopes the mitochondria. For this, the mitochondrial ATP/ADP transporter takes part to transport ATP out of the mitochondria and ADP within the mitochondria.
In deducing the evolutionary relationships among dogs, do you think it would be better to use a sequence that is neutral or one that is under selection? Explain your answer
Answer:
a neutral marker
Explanation:
A gene polymorphism can be defined as the existence of two or more variants of the same gene (i.e., alleles). A polymorphism may be a difference of one nucleotide base in DNA (single nucleotide polymorphisms, SNPs) or indels (i.e., insertions and deletions). A gene under selection will have many polymorphisms in its sequence which may lead to convergence and disproportionate divergence among sequences, and thereby will be uninformative to trace the evolutionary history among individuals within a species, population, etc. Conversely, neutral molecular markers exhibit fewer nucleotide differences, it is for that reason that they are commonly used to determine genetic population structure among individuals.

Evaluate how wind energy can be used to conserve resources
Answer:Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling. Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.
Explanation:
Explanation:
Wind is a non-fossil fuel and will never run out, so you can spend regular fossil fuels more conservatively
Identify which statement describes a scientific law
Answer:
Newton's three laws of motion are examples of laws in physical science. A scientific law states what always happens but not why it happens. Scientific theories answer “why” questions.
Explanation:
How can a longer seed be an advantage to the Red Mangrove?
Explanation
Once the propagule drops from the parent tree there is an obligate dispersal period which each species’ propagule must remain in the water. During this period embryonic development continues. For the red mangrove this dispersal period is the longest at 40 days. The black mangrove’s propagule must drift for at least 14 days. The white mangrove’s dispersal period is the shortest at 5 days, which also includes germination.
