An unidentified plant produces spores, has many cells, but does not have true leaves. What plant is it?
A. liverwort
В. fern
C. gymnosperm
D. angiosperm
An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.
What are angiosperms?Angiosperms, that are also known as flowering plants, have “seeds” that are sealed off within an “ovary”, while gymnosperms do not have fruits or flowers and have uncovered seeds on the surface of leaves. Seeds of gymnosperms are often arranged as “cones”.
The features and characteristics that distinguish angiosperms from gymnosperms are fruits, flowers, and “endosperm” in the seeds. Examples of “Angiosperms” are “monocots” like orchids, lilies, agaves, grasses and dicots like, peas, roses, sunflowers, maples and oaks. “Gymnosperm” examples include “non-flowering evergreen” trees like pine, fir and spruce.
Therefore,An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.

Describe the steps of protein synthesis in a eukaryote.
The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.
The second step is translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.
Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.
What is protein synthesis in a eukaryote?The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.

Answer:
Proteins
Explanation:
Proteins are made up of many repeating units (monomers) of amino acids that are joined by peptide bonds.
Hope this helps :)
The type of molecule is formed from amino acids is - option C. proteins because when connected together by a series of peptide bonds, amino acids form a polypeptide or protein.
Proteins are large macromolecules made of long chains of amino acid monomers, therefore, amino acids are building blocks of proteins. The amino acids are joined by peptide bonds, which form a long chain of polypeptides or proteins.
Required for the functions, structure, and regulation of the body of organisms.There are 20 different amino acidschains of amino acids fold up in complex ways to provide a unique 3D shapeThey also assist with the formation of new molecules by genetic material.Thus, the correct answer is -option C.

If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a green offspring?
Answer:
yy
Explanation:
it can only be yy because you need 2 recessive genes to show a recessive trait.
A plant with Yy genes could pass the recessive genes on, but would still show the dominant trait.
The possible genotype of the green offspring is yy, i.e., recessive one and will express only in absence of dominant allele.
What is genotype?In a broad sense, the word "genotype" refers to an organism's genetic makeup; in other words, it describes an organism's entire set of genes.
In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.
A genotype is a classification of the type of variant found at a specific location (i.e., a locus) in the genome.
Symbols can be used to represent it. For example, the letters BB, Bb, bb could be used to represent a specific variant in a gene.
In the given scenario, Y is dominant allele which will express in combination with y means the recessive one.
Thus, for expressing the green allele, it should be yy.

New seed does not germinate in spite of suitable environment Why?
Answer:
All seeds do not germinate to form new plant because some are not fulfilled with the appropriate amount of nutrients.
Explanation:
A new seed does not germinate in spite of a suitable environment due to a lack of enough nutrients in the soil, a seed may undergo the dormant stage, and too much or little water in the soil.
What is Germination?Germination may be defined as a process through which a seed grows into a seedling.
A lack of nutrients does not deliver enough energy to seed for germination. If the soil has too little water or no water, a seed remains dormant throughout, while if it has too high water, then the seed becomes susceptible to infections.
Under all the above conditions, a seed will germinate into a seedling in spite of a suitable environment.
Therefore, it is well described above.
