Which statement best describes the observations made by students after spraying water on the model to simulate rain?

Answer:

The correct answer would be - C. Scientists breed cows that give greater amounts of milk than their ancestors

Explanation:

Natural selection is the process of adapting according to the new changes in condition and change accordingly to survive. So the individuals of organisms that are better and adapt faster to survive and reproduce better than others are the result of natural selection.

Plants developed thorns so they can be avoided by predators is the adaption and example of natural selection. Similarly, bacterial populations adapt and develop resistance to the drug. Fruit fly larva developed and adapt as well. Breeding cows for more amount of milk than ancestors by scientists is not natural selection.

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Answer:

In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Explanation:

Storage, waste disposal and structural support  are the functions of vacuoles, lysosomes, and the cytoskeleton.

The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.

During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function. They release the carbon dioxide into the air as a waste product.

Answer: Organisms

Explanation:  Shelter, find food, reproduce, and rear their young in provide jobs for local communities, and offer opportunities for recreation. These ecosystems are culturally important to indigenous people

Answer:

The correct answer is - Behavioral isolation.

Explanation:

In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.

It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.

Explanation:

Answer:

Bacterial populations employ native defenses against antibiotics that are analogous to the activity of protonophores. These mechanisms disrupt membrane electrochemical gradients that enable bacterial populations to establish subpopulations of drug-tolerant persisters

D.  Traveling to the heart

Explanation:

The arteries carry oxygen and nutrients away from your heart, to your body's tissues. The veins take deoxygenated blood from the tissues and back to the heart.

Answer:

Positive growth.

Explanation:

The general pattern of population growth in the greater Atlanta area from 1990 to 2000 is positive means there is increase occur in the population. The population of greater Atlanta in 1990 is 2,184,000 while on the other hand, the population of Atlanta is 3,522,000 in the year 2000. So there is 1,338,000 people increase occur in 10 years of duration from the year 1990 to 2000. So we can conclude that the pattern of population is positive and upward.

Answer:

diluted genetic investment in offspring.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

Generally, asexual reproduction produces more reproductive offsprings than sexual reproduction, this is referred to as a reproductive handicap.

Hence, the reproductive handicap for sexual reproduction refers to diluted genetic investment in offspring.

This ultimately implies that, the sexually reproducing female would have a 50% genetic material passed to its female and male offspring.

However, sexually reproducing female has 100% transfer of her genetic materials through asexual reproduction.

Answer:

It would mimic the behavior of the earth's atmospheric atmosphere where you have a water cycle and sunlight which aids photosynthesis.

Explanation:

A terrarium is a glass container that can be covered and opened at will. It can be used to grow a plants using soil.

When it is sealed, water evaporates onto the body of the glass and runs down the sides of the glass only to be evaporated again and the same process happens over and over again.

Because the plants are in a glass container, they can still access sunlight for photosynthesis.

Sometimes the glass is opened up for maintenance. Maintenance here refers to the removal of algae that sometimes forms on the inner walls of the terrarium. Sometimes, there is also need to add water to the ecosystem in the terrarium given that the water inside usually escapes via evaporation over time.
