Biology
1 answer:
Brut [27]3 years ago
8 0

Explanation:

Simpler methods for isolation of a pure culture include: (i) spread plating on solid agar medium with a glass spreader and (ii) streak plating with a loop. The purpose of spread plating and streak plating is to isolate individual bacterial cells (colony-forming units) on a nutrient medium.

Did the Florida Panther become endangered because of natural selection, genetic drift, or gene flow?
Natalija [7]

Answer:

ALL OF THE ABOVE

Explanation:

Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics.  Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.

While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.

Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.

Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.

All these causes are related and therefore affects the Florida Panther.

Why are shadows longer in the morning and evening?
Luden [163]

Answer:

Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. ... As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!

The mitochondrion, like the nucleus, has two or more membrane layers. How is the innermost of these layers different from that o
tensa zangetsu [6.8K]

Answer:

The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature  to increase the surface area for reactions (electrochemical  gradient) by accommodating protons pumped into it by the proton motive force(PMF)  from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.

Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.

A dumping site in the small town of Love Canal, New York, was used for the disposal of industrial chemical wastes from 1970-1975
zheka24 [161]

Answer:

There is no control group and variables were not addressed.

Explanation:

In the context, it is given that there is a dumping ground in a small town called Love Canal and harmful chemical waste of industries are dumped there. Lately, it is noticed that there were traces of the toxic substances on the walls of the schools and the hospitals. The hospitals also noticed that during the period of 1970 to 1980, there were increase in the number of the birth defects in the area. The people of the Love Canal has genetic abnormalities and the chemical waste is responsible for it.

Thus it can be concluded that there is a no such any control group in this case. The confounding variables like the comorbidities as well as the family history of the genetic defects were not addressed.
