Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
Answer:
Suppose an abundance of hunting decreases the number of foxes in the ecosystem. Which of the following is the most likely impact of this decline in the fox population?
Once there is abundance decrease in hunting number of foxes in the ecosystem, there would be an increase in the population of foxes as a result of increase in birth rate and no death rate recorded, once there is unavailability in either predator and prey relationship it would benefit one, just as in the case of foxes mentioned above, since there is decrease in hunting number, hence; increases in number of foxes population
Explanation:
Answer:
Soil health is fundamental for a healthy food production. It provides essential nutrients, water, oxygen and support to the roots, all elements that favor the growth and development of plants for food production
Explanation:
They are changed because of the environments changing
Answer:
Biodiversity includes diversity within species (genetic diversity), between species (species diversity), and between ecosystems (ecosystem diversity). ... Biodiversity loss disrupts the functioning of ecosystems, making them more vulnerable to perturbations and less able to supply humans with needed services.
