A point mutation affects a single base and most commonly occurs when one base is substituted or replaced by another. Frameshift mutation results from the addition of one or more bases, known as an insertion, or the removal of one or more bases, known as a deletion.
Answer:
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
Explanation:
pretty sure its D
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Answer:
The leaves of the branches of the forest and garden trees are very valuable roughage for goats in winter. It can replace up to half of the estimated roughage for the day, ie. 4-5 twigs weighing 2 kilograms. The nutritional value of wallets is about 2 times less than that of hay. The most nutritious is acacia, followed by willow, hazel, elm, linden, oak, ash, maple, pear, quiver, poplar, etc. Regardless of the type, the most nutritious are the leaves prepared in June and July, while the branches of the trees are still tender and not completely woody.
The Nucleus of a neuron is an oval shaped membrane-bound structure found in the soma or body of the neuron. It contains the nucleolus and chromosomes, necessary for the coded production of proteins within the cell. The nucleolus of the nucleus produces ribosomes. The genetic information of an organism is coded within the long strands of deoxyribonucleic acid (DNA) from which the chromosomes are made. DNA is composed of two long chains that are interconnected in a helical arrangement. The sub units of a chromosome (genes) when activated induce the production of messenger ribonucleic acid (mRNA). mRNA is a duplicate of the information contained in the gene. mRNA leaves the nucleus and attaches to a ribosome, where is serves as a template for the production of a protein molecule
Parts of a neuron
Neurons vary in size, shape, and structure depending on their role and location. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites.
1. Cell body
2. Axon
3. Dendrites
Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. Dendrites or nerve endings.
