3. What can you conclude about the effect of exercise on breathing rate? Why is this so?
Answer:
When exercising your muscles need more oxygen. Therefore your heart needs to pump more blood (which carries oxygen) to your muscles.
Which statement is true about the nitrogen bases in DNA and RNAI
Answer:
Uracil (U) is found in RNA only. Thymine (T) is found in DNA only.
Explanation:
DNA has the nitrogenous bases adenine (A), thymine (T), guanine (G), and cytosine (C). On the other hand, RNA has the nitrogenous bases adenine (A), uracil (U), guanine (G), and cytosine (C).
Thus, only RNA has uracil (U) and only DNA has thymine (T).
Regarding Natural Selection, what does the term FIT mean?
Answer:
to an evolutionary biologist fitness simply means reproductive success and reflects how well an organism is adapted to its environment.We call them fit because of how successfull they reproduce not how well they do at athletic events
Explanation:
Answer:
The term "fitness" in evolutionary biology means the ability of an organism to pass on its genetic material to its offspring. Biological or "Darwinian" fitness is being able to live long enough to reproduce and keep the population or species alive.

Took The TestIdentify examples of adaptation in organisms
(Do not use the artic fox example)
Answer:
Frog adaptations
- thin skin which allows them to breathe through their skin
- strong hind legs and feet allow them to jump long distances
- small, thin body structure which allows them to be excellent swimmers
- bulging eyes allow them to be better hunters
Answer:
Camouflage, mimicry, and animals' body parts and coverings are physical adaptations. The way in which an animal behaves is an adaptation, too—a behavioral adaptation . Behaviors that animals are born knowing how to do are instincts . A lion preying upon a zebra and a bird building a nest are examples of instincts.

The diagram shows a plant cell before and after it is placed in a solution. After the cell is placed in the solution it changes shape.
Which table shows the initial concentration of solute in the cell and in the solution that would cause the cell to change shape,as shown in the diagram above?
A. Location-Solute Concentration
Inside cell-3%
Outside the cell-6%
B. Location-Solute Concentration
Inside cell-7%
Outside sidd-5%
C. Location-Solute Concentration
Inside cell-0%
Outside cell-0%
D. Location-Solute Concentration
Inside cell-12%
Outside celk-12%
Answer:
The answer is A.
Explanation:
The tonicity is hyper tonic solution. There is more water inside the cell and high solute concentration outside the cell. The water moves out of the cell and the cell shrinks. The plant will plasmolyze.
Here it is showing that the concentration inside the cell is 7% and outside is 5%. The correct option is B.
What is tonicity?Tonicity is a measure of the effective osmotic pressure gradient in chemical biology; the water potential of two solutions separated by a partially permeable cell membrane.
To describe whether a solution will cause water to move into or out of a cell, three terms are used which are hypertonic, hypotonic, and isotonic.
When a cell is immersed in a hypertonic solution, there is a net flow of water out of the cell, causing it to lose volume.
The direction and extent of osmotic flux are determined by the relative concentration of selective membrane-impermeable solutes across a cell membrane.
It is frequently used to describe the swelling-versus-shrinking response of cells immersed in a solution.
In the given image, the solvent concentration increases in the second image, which means its solute concentration was more and water concentration was less.
So, water translocated from outside the cell to inside.
Thus, the correct option is B.

A couple is having a baby. They go to the doctor to find out the sex and they see
that the chart has the sex chromosomes as XX. Are they having a boy or a girl?"
answer:
a girl
explanation:
the X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual. females inherit an X chromosome from the father for a XX genotypemales inherit a Y chromosome from the father for a XY genotypemothers only pass on X chromosomesHow does fossil evidence support the scientific theory of evolution?

What happens when a parent passes on a dominate gene to their
offspring? *
The phenotype is a mixture of both
The phenotype is risidom
O The recessive gene determines phenotype
The dominate gene determines phenotype
Answer:
The dominant gene determines phenotype
Explanation:
This is because some parents have dominant and recessive alleles. when they pass them on to their offspring,the more dominant genes they have,the higher the chance that trait will show in their offspring.
When a parent passes a dominant gene to their child, the dominant gene determines the phenotype.
What are dominant genes?Dominant genes are those that determine a hereditary trait even when in single dose in the genotype. That is, they determine its character even in the absence of its dominant allele.
With this information, we can conclude that when a parent passes a dominant gene to their child, the dominant gene determines the phenotype.

Answer:
Explanation:
During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
