True
DNA are cells that carry genetic codes and are passed down through generations of offspring. New cells can only arise from existing cells!
The question is incomplete as it does not have the options which are:
- Simple squamous
- Simple columnar
- Pseudostratified squamous
- Stratified squamous
- Stratified columnar
Answer:
Stratified columnar
Explanation:
Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.
In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.
Therefore, the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.
Thus, Stratified columnar is the correct answer.
Answer: C) The cell can produce energy for cellular functions.
Explanation: A cell is the functional unit of all living things. Cells are made up different parts with specialized functions. Cells take in nutrients from food and convert them to energy which is needed for other cellular functions. The specialized functions of the different parts of a cell can only be carried out if sufficient energy is provided by the cell. The functions of different parts of a cell include reproduction, absorption of nutrients and removal of substances from the cell, protein synthesis but none of these functions will be carried out if energy is not supplied.
Explanation:
The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.
Answer:
The equation/formula to find acceleration from a velocity time graph is....
acceleration = velocity / time
