Answer:
Disease
Explanation:
In Ecology, certain factors that affect the size of a population can either be dependent on size or not. Density-dependent factors are those factors that affect population of organisms in dependence of how dense the population is. Examples of these density dependent factors are diseases, predation etc.
For example, a certain disease will spread faster among a population of organisms whose size is dense but slower in a scarcely densed population. Hence, disease as a factor is dependent on population size. Note that; Drought, Climate, and Natural Disasters will wipe out a population irrespective of its size.

Justin wants to know how much gas his mother will save if he rides his bike to school rather than being driven in the car. For one month, Justin rides his bike to school. Every week, he asked his mother how much gas she put in the car. The next month, Justin had his mother drive him to school. Again, every week he asked her how much gas she put in the car. What could Justin do to improve this experiment?
Answer:
ask his mother?
Explanation:
Answer:
To improve the experiment, Justin should have created a hypothesis and could have repeated the experiment to see if the results were at least similar.

What patterns do you observe on the second colorful map
Answer:
Patterns are used when they help to maintain the basic color scheme on complex maps; they often can effectively show relationships between units as well as imply the type of rock being represented. Patterns are most often used for surficial and for igneous and volcanic units.

The stage of mitosis where the chromosomes line up
Answer:
Metaphase
Explanation:
Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.
Answer:
It is metaphase.
Explanation:
In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.

Explanation:
Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. decrease the rate of oxygen diffusion from the alveoli to the blood. increase the partial pressure of carbon dioxide in the alveoli. decrease the rate of carbon dioxide diffusion from the blood to the alveoli. have no effect on either the partial pressure or diffusion rate of gases.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
The air in the thermosphere becomes thinner and thinner until it fades into space. True or false
Answer:
Well to be honest there are no unmistakable separating lines. Each layer mixes into the layer above it and the layer underneath it. Researchers are certain that the air becomes thinnerand more slender farther from the Earth's surface, until it at long last blurs off into space.

In which kingdom would you place an organism that reproduces by spores, is made of many cells enclosed by cell walls, have a nucleus, and are heterotrophs?
plant
fungi
bacteria
animal
Answer:
Fungi
Explanation: Fungi reproduce by spores, they are enclosed by cell walls, they have a nucleus as they are eukaryotic, and they are heterotrophs as they do not contain chloroplasts
When certain molecules accept and then donate electrons, they also pick up H+ ions in the matrix, then release them into the inter membrane space.

What can the presence of different types of fossils tell us about how this environment changed over time?
a. This environment has been an ocean from long ago through more recent times.
b. This environment has slowly changed from being an ocean to a swamp to a forest.
c. This environment has gotten much cooler over the period of time represented by these fossils.
d. This environment has become covered with water.
Answer:
B. the Environment has slowly changed from being an Ocean to a Swamp to a Forest.
Explanation:
makes the most sence when comparing it to the picture
Answer:
b. This environment has slowly changed from being an ocean to a swamp to a forest.
Explanation:
As we can see, there are water creatures in the first picture, then there were frogs and dragonflies, which are commonly found in swamps (crabs too). We see tree leaves and frogs in the last picture, which are common in forests.

Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?
Answer:
RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.
These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.

A virus infects a lung cell and begins replication. The lung cell releases interferon into the extracellular environment where it can be picked up by other nearby cells. As a result, the other nearby cells slow down their protein-making machinery to slow down viral replication should they become infected. This is an example of what kind of communication
Answer: The options are not given but it is gotten from another websites and here are the options.
A.Cell-to-cell (membrane molecule) recognition
B. Cell junctions
C. Paracrine signaling
d. Synaptic signaling
The correct option is C.
Paracrine signaling.
Explanation:
This is because in paracrine signaling cell communicate with other near by cells through chemical Messengers. It is a form of cell to cell communication in which a cell produced signal and transfer it to other neighbouring cells whereby the neighbouring cells alter or change their behavior to counter the effect of the signal. From the question, the lung cells send signals to neighbouring cells and this alter their behavior by slowering down protein making machinery.

What is Sustainable practice?Sustainable practices are described as supporting ecological, human and economic health and vitality. Sustainability recognizes which resources are limited. It should be used conservatively and wisely which take into account long-term priorities and consequences of the way resources are used.
Reduce, reuse and recycle are the basic principles of wise use of resource. Natural resources are conserved and protected by deploying these principals by reducing landfill waste, energy consumption and pollution.
Some sustainable practices are:
By reusing paper and plastic bags for shoppingBy opting for paperless documentsBy avoiding disposable kitchen itemsThus, a society uses this sustainable practice because it reduces the amount of carbon dioxide in an area. So, the correct option is (A).
