Mendells theory of
genetics aplys to what
organism
Answer:
Pea plants
Explanation:
Mendelian Theory of Genetics In the 1860s, Mendel introduced theories of inheritance, based on his experimental work with pea plants. Before Mendel, most people believed inheritance was due to a blending of parental ‘essences’, much like how mixing blue and yellow paint will produce a green color.
Which of the following types of organisms are required to complete the nitrogen cycle, including the process of denitrification?
A
Bacteria
B
Producers
С
Consumers
D
Fungi
Answer: A Bacteria
Explanation:
Bacteria is required to complete the nitrogen cycle including the process of denitrification ( A )
The nitrogen cycle is the process whereby nitrogen moves from the atmosphere into the soil and from the soil back to the atmosphere. during the nitrogen cycle, nitrogen fixation takes places ( conversion of nitrogen gas into inorganic nitrogen compounds ).
Certain bacteria ( Azotobacterial and archaea ) are the organisms responsible for nitrogen fixation and the process of denitrification.
Hence the organisms required to complete the nitrogen cycle including the process of denitrification is Bacteria

Horse tail and mucor are not kept in the same kingdom. Why?
Horse tail (Equisetum) and Mucor are not kept in the same kingdom as they belong to different kingdoms because they exhibit distinct characteristics and are classified based on their evolutionary history, cellular organization, and reproductive strategies.
Horse tails, also known as horsetails or Equisetum, are members of the plant kingdom, specifically the division Equisetophyta.
They are vascular plants that reproduce by spores.
Horse tails have a unique appearance, with jointed stems, whorls of tiny scale-like leaves, and reproductive cones at the tips of their stems.
They have a complex life cycle with alternation of generations, including both a sporophyte (dominant diploid phase) and a gametophyte (haploid phase).
Their cells have a rigid cell wall composed of cellulose, a characteristic feature of plant cells.
On the other hand, Mucor belongs to the kingdom Fungi.
Mucor is a genus of fungi within the phylum Zygomycota.
Fungi are eukaryotic organisms that lack chlorophyll and obtain nutrients through absorption.
They have a filamentous body structure called mycelium, composed of thread-like hyphae.
Mucor reproduces asexually through the production of spores, which are formed by the fusion of genetically distinct hyphae.
Fungi are heterotrophic, meaning they obtain their nutrients by breaking down organic matter in their environment.
The differentiation of horse tails (plants) and Mucor (fungi) into separate kingdoms is based on fundamental differences in their cellular organization, nutritional strategies, and reproductive mechanisms.
While both horse tails and Mucor are multicellular organisms, they belong to distinct lineages of life with diverse evolutionary histories, leading to their classification in separate kingdoms.

A mutation occurs in the coding region of a gene with the following sequence AAGTGC. The translated sequence is Lysine (AAG), Cysteine (TGC). Give an example of the following types of mutation using AAGTGC as your normal sequence. Provide the translated sequence caused by the mutation. (Hint: You will need a codon table to translate the sequence)
(a) Synonymous mutation
(b) Non-synonymous missense mutation
(c) Non-synonymous nonsense mutation
(a) Synonymous mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A synonymous mutation occurs when a gene changes its nucleotide sequence but the amino acid sequence remains unchanged. An example of this type of mutation using AAGTGC is AAGTGT. The translated sequence would still be Lysine (AAG) and Cysteine (TGT). This is because TGT is a codon for Cysteine, so the amino acid sequence remains unchanged.
(b) Non-synonymous missense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous missense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is also changed. An example of this type of mutation using AAGTGC is AAGTGA. The translated sequence would be Lysine (AAG) and Glutamic acid (TGA). This is because TGA is a codon for Glutamic acid, so the amino acid sequence is changed from Cysteine to Glutamic acid.
(c) Non-synonymous nonsense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous nonsense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is changed to a stop codon. An example of this type of mutation using AAGTGC is AAGTAA. The translated sequence would be Lysine (AAG) and Stop codon (TAA). This is because TAA is a codon for Stop codon, so the amino acid sequence is changed from Cysteine to Stop codon, which causes the protein to be truncated.

Why does a more generalized and flexible feeder (red fox) sometimes have a
competitive advantage over a more specialized feeder like the giant panda?
A more generalized and flexible feeder (red fox) has several food sources, and a more specialized feeder like the giant panda has a restricted diet.
The red fox is an omnivore?To be classified as an omnivore, the animal needs to eat both animal foods and plant foods. Most omnivorous animals are “opportunists”, that is, they choose the foods they find most easily.
With this information, we can conclude that opportunistic omnivores tend to adapt more easily to new conditions imposed by the environment.

Why do some researchers prefer to use embryonic stem cell in medical research?
A. There is no controversy surrounding the use of embryonic stem calls
B. The use of embryonic stem cell is much less expensive than the use of adult stem cells
C. No living tissue is damaged when scientists use embryonic stem cells
D. Embryonic stem cells are able to differentiate into a wider range of call than adult stem cells
Answer:
Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury
The researchers prefer to use embryonic stem cell in medical research as Embryonic stem cells are able to differentiate into a wider range of call than adult stem cells.
What are the functions of embryonic stem cells?A blastocyst, an early-stage pre-implantation embryo, is the source of embryonic stem cells, which are pluripotent stem cells. Four to five days after fertilization, human embryos reach the blastocyst stage.
The human blastocyst, an early stage of the developing embryo that lasts from the fourth to seventh day after fertilization, contains embryonic stem cells (ESCs) in its inner cell mass. In typical undeveloped turn of events, they vanish after the seventh day.
The ability to differentiate into cell types belonging to the three germ layers (ectoderm, endoderm, and mesoderm) is what is meant by the term "pluripotent." the three distinct types of tissue that are present during embryonic development and later combine to form the adult.

Maya is confused why krisn grow sowabean crop after wheat every year Can you tell why ?
Krisn grow soybean crop after wheat every year, because soybean crop is a legume.
In order for other plants that also need nitrogen to use it, the bacteria on the nodules fix nitrogen from the air into the soil. As a result, farmers rotate soybeans and other legumes with grass crops like corn or wheat.
For every acre of soil, soybeans can add between thirty and fifty kilograms of nitrogen. The more robust and vigorous the soybean crop, the more nitrogen your soil will benefit from. Soybeans start flowering on the lower nodes and progress up the stem gradually.

what term describes the measure of how quickly a carbohydrate will raise an individual’s glucose levels when consumed on its own, irrespective of the amount eaten?
Glycaemic index is used to measure the amount of carbohydrates that will raise an individual’s glucose levels.
Glucose is a sweet sugar and belongs to the class of carbohydrates.
It is obtained from food that we consume and in response our body utilizes it for energy purposes.
Glycaemic index of food refers to the time period during which carbohydrates are disintegrated and absorbed in the blood.
If GI is higher then it will enter the blood more quickly as compared to lower GI levels.
Higher GI levels means higher glucose levels in the blood and vice versa.

in the body, trans fatty acids behave like ________________ and raise blood cholesterol levels.
In the body, trans fatty acids behave like saturated fats and raise blood cholesterol levels. Saturated fats are a type of dietary fat that are commonly found in animal products and some plant-based oils. They are called "saturated" because they have a molecular structure in which carbon atoms are fully saturated with hydrogen atoms.
What are trans fatty acids?
Trans fatty acids are a type of unsaturated fat that can be harmful to your health. They're uncommon in nature and are mainly produced artificially by adding hydrogen to liquid vegetable oils to make them more solid. This process is known as hydrogenation.Trans fatty acids behave like saturated fats when they are consumed in the body. Trans fats are harmful to human health and have been linked to an increased risk of heart disease, stroke, and other chronic diseases. They can raise blood cholesterol levels and increase the risk of developing heart disease. As a result, most health experts recommend limiting your intake of trans fats to a minimum.
