A group of students wanted to compare the rate of respiration in four different fruits, as well as in tomatoes.
Brilliant_brown [7]

In this case, the dependent variable is the rate of respiration, the independent variable is the type of plant (either fruit or tomatoes), whereas a fixed variable may be the temperature.

<h3>What is a dependent variable?</h3>

A dependent variable is any type of experimental condition that is modified during the experiment.

Conversely, independent variables do not change along the experimental procedure (e.g., type of plant).

Finally, a fixed variable, also known as a control variable, is any condition that remains stable during the experimental procedure (in this case, for example, room ambient temperature).

In conclusion, the dependent variable is the rate of respiration.

A biologist discovered a young, four-legged animal. The animal had lungs, seemed to fertilize internally, and its outer surface
navik [9.2K]
The answer should be reptiles!

The characteristics of reptiles are:

1. They are four-legged

2. They have an outer covering of scales

3. They breathe with the aid of lungs

4. Although most reptiles lay eggs, some also give birth to live young (fertilise internally)!

I hope this helps! :)

Write a five paragraph essay focused on four different adaptations that hominids obtained over the last 6 million years.
Valentin [98]

Answer:Which is an adaptation?

Adaptation is the evolutionary process where an organism becomes better suited to its habitat. This process takes place over many generations. It is one of the basic phenomena of biology. ... Adaptation occurs because the better adapted animals are the most likely to survive, and to reproduce successfully.

What are the benefits of biodiversity to humans?

A healthy biodiversity provides a number of natural services for everyone:

Ecosystem services, such as. Protection of water resources. Soils formation and protection. ...

Biological resources, such as. Food. Medicinal resources and pharmaceutical drugs. ...

Social benefits, such as. Research, education and monitoring.Adaptation involves coping not only with the physical abiotic environment (light, dark, temperature, water, wind), but also with the complex biotic environment (other organisms such as mates, competitors, parasites, predators, and escape tactics of prey).

The McDonald Kreitman tests of genes in the human and chimpanzee genomes showed many with an excess of nonsynonymous variation w
kondaur [170]

Answer:

A mutation may be bad and good depending on the particular environmental conditions

Explanation:

For example, the falciform anemia is a hereditary disease caused by a mutation where the ability to transport oxygen of red blood cells is reduced; however, this genetic disorder is widespread in some African populations because it is a condition that confers resistance to falciparum malaria. In consequence, falciform anemia is a detrimental mutation that may also be beneficial in endemic malaria regions.

Moreover, it is important to note that the higher proportion of non-synonymous substitutions are not subject to selection (only a minor percentage are positively selected) because they are generally localized within non-coding regions, thereby having neutral status.
