Answer:
a.
Explanation:
caribou maternity pens are enclosed areas created to care for pregnant female caribou and their offspring. As well as allowing the mothers to take care of their offspring in a safe and nurturing condition. Therefore the hikers passing by the pens most likely would see Pregnant females and young caribou within the pens.
Answer:
Each combination of an element with a different number of neutrons is called an isotope. The radioactive isotope is called the parent, and the isotope formed by the decay is called the daughter
Answer:
The process of gene cloning involve multiple steps. It involves many enzymes, bacterial cell, vector to produced an amplified number of cell and hence product.
The gene of interest is find and then it is carried into the bacterial cell by the help of vector.
The vector is then carried to get incorporated into the bacterial cell. In this way the bacterial cell starts replicating and the and the desired product is produced in high amount.
Answer: Food, Water, Shelter and Space
Explanation: In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
Answer:
When we look at a population, we see that an individual trait may have multiple phenotypes due to <u>genetic</u> variation in the type of protein produced.
Explanation:
The phenotype constitutes the observable traits of an individual, such as height, eye color, and blood group. The genetic contribution to the phenotype is called genotype. Some traits are largely determined by genotype, while other traits are largely determined by environmental factors. Genetic variation is the raw material from which the diverse populations of a species adapt to changes in their environment. New genetic variations arise within populations from spontaneous mutations of a gene or by immigration of individuals from genetically distinct populations. Each chromosome contains many genes, the basic functional and physical units of genetic inheritance. Genes are specific sequences of the bases that encode instructions to form proteins. The DNA sequence is the specific longitudinal arrangement of the bases in the DNA chain. Each gene has a specific DNA sequence. From a common heritage that is the gene endowment of each cell, identical in all of them, the endowment has diverse mechanisms that make it possible to express it differently in each cell and in each individual. That is, although the genetic code and the systems for decoding are basically universal, there are complex differential regulation phenomena that constitute the basis by which each individual responds differently to the environment, and by which each living cell is identified, that is , that the action of a gene, then, is subject to multiple influences external to it, capable of modifying its expressive capacity from the first step, the transcription, to the last, the post-translational transformation of the protein.
