Answer:
a. different alleles of the seed shape gene.
Explanation:
Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene locus. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.

Answer:
is the site where lipids destined for other cellular compartments are manufactured.
Explanation:
This is because smooth endoplasmic recticulum is an organelles found in eukaryotic organisms that lack membrane bound ribosomes and are found in cells that has much lipids like ovaries, testes, oil glands in the skin e.t.c. They are important in the synthesis of lipids is the site where lipids , Phospholipids, steroid hormones.

when was Nigeria amalgamated?
Answer:
January 1, 1914,
Explanation:
The typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. The available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate for about one day. After the reserve has been depleted during starvation, what other sources can be used to produce glucose
Answer:
Fats and proteins that are present in liver, kidneys, and muscles.
Explanation:
When the reserve of glucose is used by the body during starvation, our body uses fats and proteins that are present in liver, kidneys, muscles etc and convert these fats and proteins into glucose. There is high amount of fats and proteins present in our body which can be used when the glucose reserves depleted from the body during starvation so we can conclude that the fats and proteins are the sources that can be used to produce glucose for the body.

Why is carbon a very important element? A Carbon is the central element to all living organisms B. Carbon is key to producing electricity C. The Sun needs carbon to produce energe D. A all of the above
Answer:
D
Explanation:
Carbon is important in biology because without it, life itself would not exist. Carbon is important in everyday life for all living beings in order for them to live, grow, and reproduce. Carbon compounds are also very versatile and they are in many objects we use every day.
Carbon is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and organic compounds, scientists can learn more about life, the human body, and how it works. Organic Molecules Most organic molecules are made up of long rings or chains of carbon atoms with atoms of other elements attached.
The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun. Photosynthesis occurs in both land plants and ocean dwelling organisms like algae.
Carbon is the central element to all living organisms, it is key to producing electricity, and the sun needs carbon to produce energy. Therefore, option D is correct.
What is the importance of carbon?Because it is present in every biomolecule, carbon is regarded as the element of life. Carbon is a component of all vital biomolecules, including lipids, nucleic acids, proteins, and carbohydrates. The presence of four valence electrons in carbon makes it so distinctive.
The majority of the world's electricity comes from fossil fuels, which also make up the vast majority of the world's transportation fuels like gasoline and diesel. Energy is extracted from fossil fuels through the combustion of hydrocarbons.
Carbon, nitrogen, and oxygen processes convert hydrogen into helium but do not exhaust themselves, providing around 1% of the sun's energy. Hence, option D is correct.

Taigas, tundras, and tropical rainforests have a lot of sunlight
TundraIt has low temperatures throughout the year. Winter is quite severe and summer is cold.
TaigaAlso called coniferous forest due to the predominance of pine and spruce.
Tropical forestThe vegetation is dense and forms strata, depending on the canopy cover of the trees, which gives rise to different microclimates. The vegetation also has epiphytes, lianas and lichens.

* Apply Concepts A particular plants diploid number of chromosomes is 50. Describe the number of chromosomes in one of the plant's cells during its sporophyte phase and during its gametophyte phase,
Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.
Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.
A deletion mutation occuring in the region of DNA which encodes for a sigma subunit of RNA polymerase results in decreased binding to the promoter region of the DNA sequence which encodes for alpha, beta, and omega subunits of RNA polymerase. What is the effect
Answer:
The correct answer is - a reduced expression of alpha, beta, and omega subunits of RNA polymerase.
Explanation:
Sigma subunit of RNA polymerase is the subunit that the holoenzyme, the other part of the enzyme, identifies and attaches with the specific DNA site called promotors that is responsible for coding the alpha, beta, and omega subunits of this enzyme.
As it is given that there is a deletion in the sigma subunit due to mutation that results in decreased the sigma factor's binding affinity to the promoter region. That ultimately leads to less or unable to bind properly to the promoter and the level of gene expression to fall or be reduced.
