to keep your body functioning and active depending on the hormones
Answer:
true
Explanation:
due to allele sharing and the interaction between dominant and recessive phenotype . the melanin description gene is dependent on the pairing between the mating organisms. similar to fur colour in other mammals
It travels through the more dense medium until it reaches the boundary with a less dense medium. MIDDLE: At the boundary, both reflection and transmission occur. ... The reflected pulse becomes inverted when a wave in a less dense rope is heading towards a boundary with a more dense rope.
<h2>Mark and recapture method</h2>
Explanation:
Mark and recapture is a technique to measure the size of a population before fishing and hunting season;commonly used by fish and wildlife managers
- It involves the marking of number of individuals in a natural population,returning them to that population followed by recapturing some of those as a basis for estimating the size of the population at the time of marking and release
- Population size can be estimated as(N)=M*T/R
here,M=initially marked;T=total in sample second;R=marked recaptures
There are certain assumptions to this method
- Population is assumed to be closed which means no new individuals were born or immigrated into the population and none died or emigrated from the population
- The chance for each individual in the population to be caught are equal and constant for both the initial marking period and the recapture period
- One of the assumption of this method is that sufficient time must be given between the initial marking period and recapture period for all marked individuals but time period should not be very long
- Animals do not lose their mark
The tags in the given question were estimated a year there is a chance that old marked tags population might have died or emigrated(the longer the time interval the greater the chance) and hence it becomes an "open" population which violates the first law
If proportion of population changes then marked recapture method formula won't turn out be applicable
Answer:
The cells that are most affected by Primary Lateral Sclerosis are muscle cells and neurons.
Explanation:
Primary Lateral Sclerosis (PLE) is a condition that affects the portion of the peripheral nerves that are responsible for innervating the striated muscles, producing muscle stiffness and paralysis.
The cause of PLE is unknown and it produces a degeneration of the supporting tissue —glial tissue— in the lateral portion of the spinal cord and nerves, which is in charge of activating the muscle tissue. As a result, the cells most affected are the neurons, which do not fulfill their function, and the muscle cells that tend to atrophy.
The other answer combinations are wrong choices because:
- <em>Primary lateral sclerosis does not affect the epithelial tissue or the liver cell.</em>
