Explanation:

what's the question

Answer:

Due to dominant trait.

Explanation:

The best explanation for this result is that grey colour is dominant trait due to which all of the progeny appears grey while in the second example, black colour is dominant trait which appears in the all the offspring of moth. In the offspring, only that trait becomes visible which is dominant while the trait which does not appear is known as recessive trait so that's the reason due to which grey in the first and black colour in the second becomes visible.

Answer:

the answer is true because plant can be infected

by parasitic

sorry if wrong

Answer:

This is true.

Explanation:

Some plants are parasitic, which means they do not make their own food. They do, however, steal necessary water and minerals from other plants, often killing the other plants off. Parasitic plants sometimes do have chlorophyll, and others do not.

Electrons fill energy levels starting with the levels that are close to the nucleus. The levels are called orbitals and each orbital must be filled before the next orbital can be filled also the 1st orbital can only hold 2 electrons.

Answer:

it is b

Explanation:

reccesive doesn show in the phenotype because its covered by the dominant trait so the parents were fine but it is both parents so that the kid has an rr and not Rr or RR so that the reccesive trait would be covered by the dominant in the phenotype so B

Answer:

      The water cycle is the way that all water chases after as it moves Earth in various states. Fluid water is found in seas, streams, lakes—and even underground. Strong ice is found in icy masses, day off, at the North and South Poles. Water fume—a gas—is found in Earth's air.

        The water cycle, otherwise called the hydrologic cycle or the hydrological cycle, depicts the constant development of water on, above and underneath the outside of the Earth. There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

Answer:

The train will move on the roads.

Explanation:

If every state had different requirements for smokestacks or track width, the trains should be run on the roads because if there is different requirement for track width, it is impossible to run same type of train on these tracks. One another act will be done and that was to make different types of trains for each state so that they can move on the tracks. But it is impossible for having different track width, it must be of same width.

Answer:

Yes, pH and temperature affects the cell division.

Explanation:

If the temperature falls between the range of 3 °C to 25 °C, the mitosis process increases but when the temperature lowers from 3 °C and exceeds from 25 °C so it decreases the rate of mitosis process because the enzymes which is responsible for the process of mitosis denatures and does not work properly. same is the case with pH, the rate of the process will increase when the pH is neutral but decreases when the pH goes lower or higher.

Answer:

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Explanation:

In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.

In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.

The geological time scale/species scale is divided into different units of time depending on changes in the rocks and fossils. So the statement is true.

The lengthy period of time that the Earth's geologic history has taken up is known as geologic time. Starting at the beginning of the Archean Eon (4.0 to 2.5 billion years ago), formal geologic time runs to the present.

The Hadean Eon, an informal time period that runs from around 4.6 billion years ago (corresponding to Earth's first creation) to 4.0 billion years ago, is also frequently included in modern geologic time scales. The period of Earth's history that is reflected by and preserved in the planet's rock layers is known as geologic time.

Events throughout Earth's history are "calendared" according to the geologic time scale. It divides all of the time into named units of abstract time known as eons, eras, periods, epochs, and ages, in declining order of duration. Those geologic time units are counted according to stratigraphy, the correlation, and the categorization of rock layers.

Therefore, the geological time scale is used for dividing different units of time according to changes in rocks and fossils. Hence the statement is true.

PRIMORDEAL seas absorbed GASES of the atmosphere,There  was a heavy concentration of ultraviolet radiation from the sun, and frequent LIGHTNING strikes, and the environment was helpful in producing ORGANIC molecules from INORGANIC  molecules.

Gases are absorbed by the primordial seas and lightning strikes in earth helpful in producing inorganic molecules from  organic molecules  mostly present in living things.

Oceans of earth in the earlier time is called as primordial seas in the history . Primordial seas creates heavy rain last for long time.

Lightening in earth is caused by electrostatic charge from the ions in the atmosphere. Lightening is followed by thunder. Lightning helps to produce oxides and nitrogen in the atmosphere.

Answer:

false

Explanation:

traits are determined by more than two genes.

Answer:

Explanation:

Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.

For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.

Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.

For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .

Answer: Nine years ago I jumped at an opportunity to join the international team that was identifying the sequence of DNA bases, or “letters,” in the genome of the common chimpanzee (Pan troglodytes). As a biostatistician with a long-standing interest in human origins, I was eager to line up the human DNA sequence next to that of our closest living relative and take stock. A humbling truth emerged: our DNA blueprints are nearly 99 percent identical to theirs. That is, of the three billion letters that make up the human genome, only 15 million of them—less than 1 percent—have changed in the six million years or so since the human and chimp lineages diverged.

Evolutionary theory holds that the vast majority of these changes had little or no effect on our biology. But somewhere among those roughly 15 million bases lay the differences that made us human. I was determined to find them. Since then, I and others have made tantalizing progress in identifying a number of DNA sequences that set us apart from chimps.

A) the ability to remember the antigen it encounters

Adaptative immunity reacts in a more general way producing nonspecific antibodies against the foreign antigen when the organism is first attacked by that foreign antigen. The second time around, when the organism is faced again with the same foreign antigen, it produces a much stronger response because it memorised the antigen and is not strange anymore so the response can be more specific, quicker, and effective.
