Cindy/was diagnosed with anemia recently, because her physician found that her blood contains a lower count of red blood cells than normal. 4 A) What is anemia's immediate impact on gas exchange?
Answer:
The correct answer would be - a decrease in the numbers of RBCs will lead to a decrease in the ability for gas exchange in a person.
Explanation:
In the case of anemia, there would be a decrease in the number of RBCs that might be due to increased destruction of these cells, or low production of RBCs, that transporting oxygen and carbon dioxide affects the ability for gas exchange in an individual.
RBCs carry and transport oxygen to various body parts and then carry back carbon dioxide from different parts of the body to the lungs for gaseous exchange but with less number of RBCs leads to impair or decreased gas exchange in the case of anemia.

D)A sample of distilled water
Answer:
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:
Simple random sampling. Systematic sampling. Stratified sampling, etcPlease note that your question is incomplete so i gave you a general overview which would help you get a better understanding of the topic.

What is the graphical representation of age structure known as?
OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

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.
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.

Bromine is a liquid at room temperature. The volume of a sample of bromine is measured in a 50 ml beaker and a 100 ml beaker. How will the two
measurements compare?
A. The volume of bromine will be larger in the 100ml beaker.
B. The volume of bromine will be smaller in the 50ml beaker,
C. The volumes will be the same.
D. Both A and B
The actual volume of bromine in each beaker will be same only the difference in height will be comparable. Therefore, option (C) is correct.
What are the properties of liquid ?A liquid's attributes are;
1) Compared to the volume occupied by a gas, the volume of a liquid is relatively stable at conditions that allow it to remain in the liquid state.
2) A liquid will take the form of the container it is placed in.
3) A liquid's surface in a container must be flat for the attraction forces between its molecules to be in equilibrium both at the liquid's surface and within its body.
Therefore, there will be variations in the measured height of the same volume of bromine in each beaker given that the volume of the bromine is measured in a 50 ml beaker and a 100 ml beaker.

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
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.

Which type of feather gives the bird its color?
down
barb
contour
flight
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.

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?
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.
