The prime difference between the Eubacteria and Archaebacteria kingdoms, and the Protista, Fungi, Plantae, and Animalia kingdoms is their cell wall.
Difference in the composition of cell wall in different kingdoms:A structural layer encircling some kinds of cells, that is, just external to the cell membrane is the cell wall. In all the kingdoms identified, the prime difference is seen in the composition of the cell walls present.
Following are the cell wall compositions of all the kingdoms:
In Eubacteria, cell wall is formed of peptidoglycan with muramic acid In Archaebacteria, cell wall is formed of proteins and polysaccharidesIn fungi, cell wall is formed of chitinIn Plantae, cell wall is formed of celluloseIn Animals, no cell wall is presentIn Protista, that is, the plant like protists, cell wall is formed of celluloseThus, the prime difference between all the kingdoms mentioned is the composition of the cell wall.

What are the 7 characteristics of all living organisms?Populations undergo changes throughout evolution, and the organisms inside them become better at responding, metabolising, and reproducing. They acquire coping mechanisms for their surroundings that their forebears lacked. Additionally, evolution produces a wider range of creatures than did so in earlier times.
Environmental reactions, cells, change and development, reproduction, possessing complicated chemistry, homeostasis and energy processing are the seven traits that define a living being. Non-living creatures may sometimes exhibit some of the aforementioned traits, but only live organisms exhibit all of them.

How do individual cell parts contribute to a cell's division?
Answer:
Centrioles are organelles involved in cell division. The function of centrioles is to help organize the chromosomes before cell division occurs so that each daughter cell has the correct number of chromosomes after the cell divides. Centrioles are found only in animal cells, and are located near the nucleus.

Mendel wanted to find out if the pattern of the inheritance for one trait affected the pattern of inheritance for another what experiment did he perform to test this idea
Answer:
This question lacks options, the options are:
A. He tested non-dominant traits.
B. He performed dihybrid crosses.
C. He made an F3 generation.
D. He tested one trait at a time.
The answer is B
Explanation:
Gregor Mendel, who is referred to as the FATHER of GENETICS, discovered the principles that governs inheritance till date. In one of his principles which he called LAW OF INDEPENDENT ASSORTMENT, he stated that the separation of one allele of a gene into gametes does not influence the separation of the allele of another gene i.e alleles of genes segregate independently of one another.
In order to test this principle, Mendel performed a DIHYBRID CROSS, which is a cross where the inheritance of two different traits encoded by two different genes are simultaneously studied. For example, he studied the gene for seed shape (round or wrinkled) and seed color (yellow or green) in pea plants. By performing this DIHYBRID CROSS, he was able to test his idea that pattern of the inheritance for one trait (seed shape) did not affect the pattern of inheritance for another (seed color).

Fully explain in your own words your thoughts on the following questions: Are mutations good or bad for a population?, IN YOUR OWN WORDS
Answer:
mutations can be either beneficial or harmful depending on the environment
Explanation:
Mutations can be defined as genetic changes in the nucleotide sequence of the genome of one organism. Mutations are usually neutral, but they can also be deleterious and/or beneficial depending on the environment. For example, recessive mutations that cause sickle-cell anemia, which is a recessive genetic disease that affects homo-zygous individuals, have shown to be advantageous for heterozygous individuals living in regions where malaria is endemic. Beneficial mutations can be selected by natural selection, thereby increasing their frequency in the population.

Answer:
When monchondria stops you would be able to control your ATP.
Explanation:
Answer:
For our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.
1) Which of the following activities would employ isometric contractions?
a) Flexing the elbow
b) Chewing food
c) Maintaining an upright posture
d) Running
e) Writing
Answer:
c. Maintaining an upright posture
Explanation:
"Isometric contraction" is all about increasing the tension in the muscles without shortening or lengthening the length of the muscles. There's also no movement.
Among the choices above, it is only "Maintaining an upright posture" that doesn't have movement; therefore, this employs the isometric contraction. This kind of contraction increases a person's strength. Another example of this contraction is holding a weight overhead.
What's the similarities between phenotype and genotype? Pleaseeee help meee
Background: Phenotype is how a genetic trait physically looks, while genotype is the trait expressed as two letters.
Example:
-The genotype is BB
-The phenotype is brown hair
-The genotype is bb
-The phenotype is blond hair
-The genotype is Bb
-The phenotype is a mixed light brown hair
Therefore:
Both phenotype and genotype are expressions of genetic traits, but the phenotype is the letter form, and the genotype is the physical appearance/description.

Complete table of digestive enzymes is:
Food type Enzyme acting on the food type Simpler substances produced
Protein Protease Amino acids
Carbohydrates Amylase Glucose
Fats Lipase Fatty acids and glycerol
Explanation:
Digestive enzymes are a group of substances whose function is to degrade food into simple compounds that can be easily absorbed by the body.
The main digestive enzymes are produced in the exocrine pancreas, corresponding to amylase, protease and lipase.
Amylase: is the enzyme responsible for breaking down carbohydrates into glucose, a simple molecule used as the body's main energy substrate. Proteases: act on food proteins to convert them into their monomers, amino acids. Lipases: are enzymes with an affinity for fats, degrading them by breaking their bonds to obtain fatty acids and glycerol.The simple molecules are easily absorbed at intestinal level, to be transported by the blood and distributed throughout the organism.
what was the role of plant breeding in green revolution?
Answer:
plant breeding played a crucial role during the green revolution
Explanation:
Plant breeding can be defined as the methodologies used to improve plant phenotypic traits. The methodologies for plant breeding include, among others, making crosses, setting breeding objectives, genetic engineering techniques, selection of progeny, etc. Moreover, the Green Revolution is a period occurring between 1950 and 1960 in which high-yield varieties were developed, specifically in rice and wheat. During this period, high yielding semi-dwarf varieties of rice and wheat arising from the cross between dwarf plants and normal varieties were developed. These high yield crops were resistant to lodging. The combination of these new varieties, fertilizers and new techniques of harvesting drastically improved crop yields, thus reducing hunger in Third World countries.

Introducing new species into an ecosystem
Being able to control an animal’s environment
Using forest management principles in woodlands
Repairing any part of the environment destroyed by a natural disaster
Answer:
B. Being able to control an animal’s environment.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Custodial management can be defined as a wildlife management technique that is typically focused on protecting or preventing any harm to the environment of living organisms such as plants and animals.
Basically, the main purpose of a custodial management is to minimize or mitigate any external influence on the living organisms and their natural habitat such as in wildlife. Thus, there are no interference by anyone on the animals in their natural habitats or wildlife.
Hence, an element of custodial management is being able to control an animal’s environment.
Which of the following is a process that changes the composition of rocks and from one mineral to another?
Complete Question:
Which of the following is a process that changes the composition of rocks from one material to another?
Group of answer choices.
A. Erosion
B. Deposition
C. Physical weathering
D. Chemical weathering
Answer:
D. Chemical weathering
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering: it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering: it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
This ultimately implies that, chemical weathering refers to a process that changes the composition of rocks from one material to another. Some of the by products of chemical weathering are clay minerals, quartz, feldspar, muscovite, etc.
