What is the important organelle that eukaryotic cells have and prokayotic cells don't have?

Answers

Answer 1
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.

6. Compare the DNA of an offspring to the DNA of its parents.

Answers

Answer: In DNA the parent duplicates itself through a process known as mitosis. Any offspring is going to have the same exact DNA as the parent. (same characteristics, everything).

The comparison of the DNA of an offspring to the DNA of its parents is determined by the fact that every offspring gets 50% of its genome from each parent, but it is always a different 50%.

How does the DNA of parents compare to that of offspring?

In the process of sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote. In other words, an offspring inherits half of the genetic material from each parent. The children resemble their parents, but they are not identical to them.

During the process of meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets. Due to this, the difference in the genetic material or DNA sequences is occurred due to the process of variations between them while DNA copying.

Therefore, the comparison is made due to the mechanism through which every offspring gets 50% of its genome from each parent, but it is always a different 50%.

Answer:

The correct answer is D) Fissures

Explanation:

Karst is a topography or landform that is created by the dissolution of soluble rocks beneath the surface by waters from the surface or below.

Fissures are formed when because of earth movements there is the occurrence of a long, narrow opening, in the earth.

Artesian springs refer to the water coming out through these cracks or openings in the earth onto the surface of the Karst topography.

Answers

Answer:

Explanation:

if not I'm sorry

The zygote is basically an example of totipotent cell in humans. The correct option is B.

What is totipotent cell?

Cell potency refers to a cell's capacity to distinguish into various types of cells. The greater a cell's potency, the more cell types it can differentiate into.

A totipotent cell is a single cell that, when given the proper motherly assistance, can give rise to a new organism.

A totipotent cell is one that can generate all extraembryonic tissues, as well as all body tissues and the germline.

The term "totipotent" refers to a cell that has the ability to split and produce all differentiated body cells, both embryonic and extraembryonic.

Zygotes and spores are instances of totipotent cells in animals.

Thus, the correct option is B.

©2021 Illuminate Education Inc.

Answers

Answer:

hmm

Explanation:

On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

Plausible solution to human activities contributing to increasing amounts of carbon dioxide(carbon emission) in the atmosphere are :

Use only alternative energies for the production of electricity
Require all new automobiles manufactured to run on electricity rather than gasoline.
Plant more trees and decrease deforestation practices so that more carbon dioxide can be absorbed from the atmosphere.
Require everybody to use mass transportation or methods of transportation that do not require burning fossil fuels, such as riding bicycles.

What is carbon emission ?

Carbon emission (greenhouse gas emissions) from human activities strengthen the greenhouse effect, causing climate change. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.

Alternative energy is energy that is collected from renewable resources that are naturally replenished on a human timescale, hence contributing to betterment of environment.
Electric automobiles do not cause carbon emission.
Trees absorb the carbon dioxide from the environment and release oxygen.
Mass transportation will cut the cut out the percentage of carbon emission by several folds.

The genetic code was elucidated through the use of polyribonucleotide's synthesized either enzymatically or chemically in the laboratory. Given what we now know about the genetic code, how would you make a polyribonucleotide that could serve as an mRNA coding predominantly for may Phe residues and a small number of Leu and Ser residues?
What other amino acid(s) would be encoded by this polyribonucleotide, but in smaller amounts?

Answers

Answer:

The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the serine and lysine residue in a small amount.

EXPLANATION:

The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The formation of the RNA stand is done by using ADP, GDP, CDP, and UDP (adenosine, guanosine, cytosine, and uridine diphosphate). It requires no template for the formation of polymers. Therefore incorporation of UDP is done by the incorporation of polynucleotide phosphorylase, which will result in the formation of poly U. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the ser and lysine residue in a small amount. For example in the stretch of polynucleotide UUU presence of one of the following codon UUA, UUG, CUU, CUC, CUA, CUG as well as UCU, UCC, UCA, UCG, and AGU can synthesize leucine and serine residues. (UUC)n can synthesize the polymer of phenylalanine, serine, and incorporation of few A and G will synthesize leucine. However, the presence of A, C, and G can also synthesize a small amount of tyrosine, isoleucine, and cysteine residue.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells

Answers

Answer:

2

Explanation:

They either engulfy and digest pathogens(phagocytosis) or produces antibodies.

Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.

These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.

The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.

Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
