In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answers
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

Answers
Answer:
Blue Eyes Are: Recessive
Explanation:
The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.

Why can smaller cells diffuse oxygen and nutrients at a faster rate?
small surface area to volume ratio
large surface area to volume ratio
large surface area
more volume than surface area
Answers
Answer:
A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials.: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse.

How might volcanic eruptions change the flow of energy on earth?
Answers
Answer:
It causes global warming due to emission of carbondioxide gas.
Explanation:
Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.

Which type of feather gives the bird its color?
down
barb
contour
flight
Answers
it contour
I hope it work
Contour type of feather gives the bird its color. Therefore, the correct option is C.
The outer feathers that give a bird its color and general appearance are known as contour feathers. The barbs on the branches that make up the central shaft of these feathers join to form a strong, streamlined structure. The barbs have their own little branches, known as barbules, which contain pigments that help give the bird its color.
The diverse colors and patterns seen on many bird species are determined by the arrangement and color of pigments in the barbules of contour feathers. Therefore, contour feathers are important in determining a bird's color.
Therefore, the correct option is C.

D. A sample of distilled water
Explanation:
You need to have a control sample that hasn't been messed with to see what would happen if you had no reaction to your experiment
A sample is the smaller set of data which a researcher makes use of to complete a research.
As a result of this, we can see that a sample study is the use of these samples to come to a conclusion about the investigation or research which is going on.
Some examples of a sample study include:

As a frog develops from a tadpole into an adult frog, it goes through changes that are signaled by hormones within the body. Which best describes the role hormones play in changing a tadpole to a frog?
Answers
Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.
