BRAINLIEST!! Would the mass of the light bulb change as it travels from Earth to the Moon. Why or why not? please explain in a c
Shtirlitz [24]

Answer:

The light bulb will have the same mass on the moon as it will on earth. The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. For instance, if you measure your mass on Earth and then measure your mass on the moon, your mass will remain the same. The same theory applies to any object with mass.

Explanation:

hope it helps brainliest pls!! :)

After an exceptionally rainy spring, there is no longer a barrier between the populations, and some individuals migrate inland f
Naddika [18.5K]

Answer

After inland population after migration allele frequency is 0.62 or 62%

Explanation:

Given,  

Coastal striped phenotype freq. = 0.22

ss = 0.22

q_{coastal} \times q_{coastal} = 0.22

q_{2 coastal}= 0.22

Similarly, inland striped phenotype freq. = 0.43

q_{2inland} = 0.43

q_{coastal} = \sqrt{q_{2coastal}}

= \sqrt{0.22}

= 0.4690

q_{coastal}= 0.47 i.e. 47%

q_{inland} = \sqrt{0.43}

= 0.655

q_{inland} = 0.66 i.e. 66%

the migration range (m) is given as 20%

m= 0.2

allele freq. after migration = pre migration + ∆q

here,                  

∆q = change in the allele frequency

or                    

migration of allele freq. from coastal to inland

=m(q_{coastal} - q_{inland})

= 0.2 (0.47 – 0.66)  

=0.2 \times (- 0.191)

= - 0.0382    

∆q = -0.04   i.e. 4%

According to the ____________ theory of biological aging, dna in body cells is gradually damaged through spontaneous or external
aliina [53]

The Cross-Linkage Theory or also referred to as the glycosylation theory of aging was discovered or proposed by Johan Bjorksten in the 1940s. According to this theory, the aggregation of cross-linked proteins can damage cells and tissues this slowing down the bodily processes that eventually results to aging. In recent studies, cross-linking is associated with age-related changes in the studied proteins. Furthermore, this theory stresses out that the binding of glucose to proteins can cause various problems. Once the said binding occurs, the protein becomes impaired which leads to its performance inefficiency. Living a longer life would also mean increasing the possibility of oxygen-glucose meeting and protein. Some of the known cross-linking disorders include senile cataract and the appearance of tough, leathery, yellow skin.

For the answer to the question above, the best stage in fern life cycle is the sporophyte stage. It is the <span>multicellular diploid stage in the life cycle of a plant or <span>algae</span></span>.<span> Developing from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell, therefore, has a double set of chromosomes, one set from each of its parentchromosomes.</span>
