Cell organelles are any of a number of organized or specialized structures within a living cell.

What is a cell?

A cell may be defined as the fundamental structural and functional unit of living organisms. Each living organism is made of a cell. It is responsible for each metabolic function that is necessary for the survival of living entities.

Inside each living cell, a fluid jelly-like substance known as cytoplasm is filled. This provides an environment for the cell to accomplish all sorts of its task. Within the cytoplasm, a number of various organized or specialized structures are present which are known as Cell organelles.

A cell organelle may be characterized as a small structure in a cell that is surrounded by a membrane and has a specific function.

Therefore, cell organelles are any of a number of organized or specialized structures within a living cell.

Why phage is consider as a nanomachine? ​

Answers

Answer:

phages are non-living biological entities that can produce numerous copies of themselves, forming ordered three-dimensional structures on a nanometre scale

Explanation:

A phage (i.e., a bacteriophage), is a virus capable of infecting and replicating within bacteria. Bacteriophages are composed of proteins forming a capsid that encapsulates the genetic material (either DNA or RNA genome), which may contain a variable number of genes. Bacteriophages, and viruses in general, can be considered nanomachines capable of producing numerous copies of themselves with high fidelity by utilizing the molecular machinery of the host bacterial cell. In biotechnology, it has been proposed to exploit the knowledge about bacteriophage reproduction to design diverse nanostructures.

Answer:

The correct answer is - option A) Some bacteria with resistance to antibiotic C were selected for overtime.

Explanation:

In the given question it is stated that the bacteria number initially declines when they are treated with antibiotic C but then started to increase as time passes on. It is clear with the given data that initially the number of bacteria declines due to bacteria does not resistant to antibiotic C but after some time some bacteria developed resistance to the antibiotic and were selected and increased overtime.

xperimenters found that in rats, a certain type of cell will fire when the animal is in a specific location and not when it is in another location. This type of cell is referred to as a _____ cell.

Answers

Answer:

hippocampal place

Explanation:

A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.

Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.

The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.

Hence, the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male and female reproductive structures d. photosynthetic signals

Answers

Answer:

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

Use complete sentences or list form in order to describe the steps of replication. You must
use the following words and underline them:

Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand
Lagging strand

Answers

Answer:

Please find the description below

Explanation:

DNA replication involves the duplication of the DNA molecule in the NUCLEUS to yield two identical copies. It involves the following steps:

- DNA molecule (double stranded) is unwound or separated into a replication fork by DNA helicase.

- The DNA, which now comprises of two single strands i.e. one strand that runs from the 3'-5' called LEADING STRAND and other strand that runs from '-3' called LAGGING STRAND.

- An enzyme called DNA POLYMERASE attaches to the DNA and adds nucleotide in a bidirectional pattern i.e. adds nucleotide to the leading strand in a 5'-3' direction, then adds short pieces of DNA called OKAZAKI FRAGMENTS to the lagging strand.

- The synthesis of nucleotides by DNA polymerase follows the COMPLEMENTARY BASE PAIRING rule i.e. A-T, G-C.

- Another enzyme called DNA LIGASE joins the okazaki fragments together into a whole DNA.

At the end of replication process, two identical copies of DNA is produced, with each containing one old strand and one new complementary strand.

Sharks' TeethBy Langston CarterThe day we found the sharks' teeth was foggy and cool. Moisture hung in the air so thick you could almost see it sparkling in the dim sunlight. There were days, early in the summer like this one, where it seemed there was more water in the air than in the bay. We had beached the boat and stepped out on the recently cleared spit of land. The ground had a light dusting of white sand over an under layer of dried black mud. It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste.

The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds. The bounty of the sea lightened everyone's hearts, and the smell of roasting fish filled the damp air. Women fanned themselves from wagon seats. Children splashed in the shallow edges of the bay.
