Answer:

The correct answer is - when a drug kills most of the bacteria, the ones left to breed are those that have a natural resistance to the drug.

Explanation:

When a drug or antibacterial medication used on the colony of a bacteria, the drug kills most of the specific bacteria from the host or culture, however, some bacteria remain to breed the next generation of bacteria as they had resistance to the particular drug.

The left bacteria breed and produce more resistant bacteria and after a few generations, a new form of drug-resistant bacteria develops. This follows the natural selection process and adapting the beneficial characteristic.

Answer:

Egg cells have 23, and zygotes have 46.

Answer:

assuming the trout is on the first and lowest branch

Answer:

25%

Explanation:

A simple way to think of the punnett square is to think of it as divided into fourths. Only one of these fourths has o type blood. Therefore, there is only a 1/4 or 25% chance of them having another child with o type blood. Hope this helps :)

According to the scenario, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.

Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. It may also be characterized as the area where the basic demands of an organism are fulfilled like food, water, space, mating partner, etc.

Grasslands habitats are generally open and continuous, fairly flat areas of grass. They are often located between temperate forests at high latitudes and deserts at subtropical latitudes. In these habitats, the availability of shelter is very low because of an abundance of small grasses across the area which is insufficient to build a shelter.

Therefore, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.

Answer:

The evolution of modern humans consisted of fossils, direct observation, anatomy, and molecular biology.

Answer:

there ya go

Explanation:

Answer:

The answer is C.

Explanation:

No dependence between the populations of the two ant species.

Answer:

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Answer:

0,45 is the population I guess

The correct answer is

B. Decrease chemical use

Answer:

Natural selection would be the other source because organisms that have a beneficial trait will live, but organisms that do not have a beneficial trait might die. So the organsims that do survive will reproduce and pass on those traits to their offspring. Eventually all the organisms that do not have a beneficial trait will die out, leaving most of the population having that beneficial trait.

Answer:During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.

Explanation:

Virus replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before their replication can occur.

Viruses may be defined as infectious microbes consisting of an element of nucleic acid surrounded by a protein coat.

There are six steps that govern the replication of a virus. They are given below:

It's amazing to see how the bees in the hive interact with one another. All of the bees in the hive are directly descended from the queen bee, who serves as the mother of the whole colony.

The only bee in the colony with the ability to reproduce is the queen, and she does it by laying eggs. The drone bee, the queen's partner, fertilises the eggs, and the larvae that result hatch into worker bees.

Given that they all have the same mother, the worker bees are all sisters and brothers. They are all also cousins since they have the same father, the drone bee. A small number of female bees known as "daughters of the queen" are also produced by the queen bee.

Additionally, these children are sisters to the These daughters are not relatives; although they are sisters to the worker bees, they are not linked to the drone bee. The queen bee can also give birth to drones, which are male bees. These drones are not relatives since they have no siblings or brothers and no connection to worker bees.

However, because they have the same mother as the worker bees, they are aunts and uncles to the latter. In conclusion, there are many relationships among the bees in the hive. They are all related since they all have the same mother, the queen bee. They are cousins because they have the same parent, the drone bee. The worker has relatives and uncles who are drones.

Static frictional force is the minimum force that must be overcome for one object to slide over another.

Frictional force is the force the acts between the surfaces of two objects in contact which oppose the motion of one object over the other.

The minimum force that must be overcome for one object to slide over another is known as static frictional force.

If the applied force is greater than static frictional force, the object will start moving over the other.

Therefore, static frictional force is the minimum force that must be overcome for one object to slide over another.
