What amino acids is represented by the codon UUA?
Answer:
Leucine
Explanation:
Leucine amino acid is represented by the codon UUA. One codon codes for only one amino acid.
What are amino acids?Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the human body to create proteins that aid in breaking down food.
There are 20 amino acids, of which 10 amino acids are essential and 10 are non-essential amino acids.
Codons made from three nitrogenous bases codes for amino acids. One amino acid can be coded by more than one codon, while one codon can code only one amino acid. For example, UUA codes only for leucine, but leucine can be coded by UUA, UUG, CUA, CUC, CUG, and CUU.

Describe how ions, water and sugar are obtained and transported
through plants. In your answer you should refer to materials moving upwards in a plant and to
materials moving downwards in a plant
Answer:
Explanation:
Water moves through the xylem in a stream called a transpiration stream, up to the leaves of the plant. Sugar is made during the process of photosynthesis. Unlike water and ions, it travels through the plant via the phloem, moving up and down through the plant.
which process is typical of cancer?
-Replacement Of Damaged Lungs
-DNA Replication
-Cellular Death
-Uncontrolled Cell Division
Answer:
Uncontrolled cell division
(and I think that HIV/AIDS Does the opposite; slows cell division)
Answer:
uncontrolled cell division
Explanation:
Cancer cells are cells gone wrong — in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy. Over time, these cells become increasingly resistant to the controls that maintain normal tissue — and as a result, they divide more rapidly than their progenitors and become less dependent on signals from other cells. Cancer cells even evade programmed cell death, despite the fact that their multiple abnormalities would normally make them prime targets for apoptosis. In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body.

are environmental factors more likely to affect genotype or phenotype?
Environmental factors are more likely to affect phenotype than genotype.
Phenotype refers to the observable physical characteristics of an organism, a product of the genetic information contained in the genotype, in accordance with the conditions of the determined environment in which the organism lives.
The phenotype supposes the manifestation of the genotype based on the environmental factors, the traits expressed by the phenotype are behavioral and physical.Regardless of the genotypic information manifested, environmental factors will also shape the phenotype of an organism, since it can suffer accidents, changes or adaptations that a genetically similar individual but in another environment would not suffer.Therefore, we can conclude that the phenotype is the variable expression of a genotype in accordance with the environmental factors.

how can the h. pylori bacteria survive in the human stomach?

Which option(s) correctly describes chromosomes?
Chromosomes consist of tightly coiled DNA wrapped around proteins called histones
Each chromosome has one gene
Chromosome pairs contain completely different genes
Most human cells have two copies of each chromosome - one from each parent.
Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.

How does a bacteriophage work.
Answer:
A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components.

Are the following organelles found in plant cells, animal cells, or both?
Nucleus
Cell membrane
Plasma membrane
Mitochondria
Vacuole
Endoplasmic reticulum
Cell wall
Chloroplasts
Ribosomes
Cytoplasm
Answer:
Explanation:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information
The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
The plasma membrane is the same as a cell membrane
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
