Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.
Answer:
1. vi. Preganglionic
2. vii. adrenergic
3. ii. sympathetic chain ganglia
4. iii. Craniosacral
5. viii. splanchnic
Explanation:
Action potential travel down preganglionic nerve fibre. They travel towards Vagus Nerve near the effector organ. These impulses arrive at cardiac plexus, which create action potential in postganlianic.
No I believe that’s False
The total productive areas in which a population, a person, or a product competes are tallied as ecological footprint. It gauges the ecological resources needed by a particular population or product to produce the natural resources it consumes (such as plant-based food and fiber products, livestock and fish products, timber and other forest products, and space for urban infrastructure), as well as to absorb its waste, particularly carbon emissions.
<h3>What is ecological reserve/deficit?</h3>
An ecological deficit happens when a population's ecological footprint exceeds the biocapacity of the space that population has access to. If a country has a national ecological deficit, it is either importing biocapacity through commerce, selling off its ecological resources, or releasing carbon dioxide waste into the sky. When a region's biocapacity surpasses its population's ecological footprint, an ecological reserve is created.
