Answer:
Erythrocyte
Explanation:
Erythrocytes, or otherwise called, red-blood cells are responsible for transporting oxygen and carbon dioxide to and from the cells and tissues. The reason for this is because of a protein called hemoglobin. The hemoglobin found in erythrocytes allow for transportation of oxygen + CO2 to and from cells.

Fill in the blanks about each of the following sequential steps of the electron transfer chain (ETC) of the inner mitochondrial membrane.
a. The initial electron donor of the ETC is _______________, which hands its two electrons off to FMN, within Complex I.
b. Electrons from both Complex I and Complex II are ultimately donated to the same molecule, ____________.
c. Within Complex III, electrons from ubiquinol are ultimately donated to ______________, which then passes those electrons on to Complex IV.
d. ______________ is the final electron acceptor of the ETC.
e. The downhill movement of electrons through the ETC creates a proton gradient across the inner mitochondrial membrane. The _________________ subunit of the ATP synthase creates a channel that allows for the downhill movement of protons from the intermembrane space to the matrix.
f. The concomitant release of free energy drives the synthesis of ATP by the ____________ subunit of that same protein.
Answer:
a. NADH
b. Ubiquinone
c. Cytochrome c
d. Oxygen
e. F0 subunit
f. F1 subunit
Explanation:
Electrons enter the Electron Transport Chain (ETC) from Nicotinamide Adenine Dinucleotide (NADH), which is an electron donor generated during different catabolic reactions (e.g., glucose oxidation). Ubiquinone or 'Coenzyme Q' is an electron acceptor that accepts electrons from both Complex I and Complex II and donates electrons to Complex III. The oxygen (O) is the final electron acceptor that accepts the electrons after they have passed through the ETC and ATPase. Complex III (also known as Ubiquinol-cytochrome c oxidoreductase) catalyzes the electron transfer from ubiquinol to Cytochrome c, which is coupled to proton translocation across the membrane. The F0 subunit of the ATP synthase forms a channel (embedded in the mitochondrial membrane) through which protons can flow. Moreover, the F1 subunit of the ATP synthase uses the energy released by the proton electrochemical gradient to drive the synthesis of ATP.

Explain why sweat accumulates on a person's skin in a hot humid
Environment
Answer:
In humid conditions where surrounding air cannot hold further water vapour, sweat evaporates slowly, if at all. As a result the body heats up. it is difficult for the sweat to evaporate and in high humidity conditions we tend to sweat more. This explains why it feels so much hotter in high humidity.

Among Delta-back stripped fish, there are two genes that segregate independently of one another. Suppose the alleles at the first locus are A (dominant) and a (recessive) and the alleles at the second locus are B (dominant) and b recessive). If an AABB fish mates with an aabb fish, and their offspring are inter-crossed, the proportion of F2 fish that show a recessive phenotype at the first locus and a dominant phenotype at the second is:
Answer:
4/16
Explanation:
It is given that the alleles of the first locus = A dominant and recessive a
The allele of the second locus = B dominant and the recessive b.
Now if fish with AABB mates with the aabb fishes, then to tell the proportion of the F2 fish which shows either the dominant phenotype at the [tex]$\text{first locus}$[/tex] and also a recessive phenotype at the [tex]$\text{second locus}$[/tex].
So for this, the recessive phenotype at the [tex]$\text{first locus}$[/tex] as well as the recessive phenotype at the [tex]$\text{second locus}$[/tex] is in the ratio of 4/16.

The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.
The attack by snakes is acting as a selective pressure on the frogs´ population. It is an ecological pressure that is modeling the frogs´ phenotype.
Animals that suffer more attacks are the blue ones, followed by green and red frogs. Those that suffer the fewest number of attacks are the yellow individuals.
So natural selection will be acting on this population favoring the alleles that code for yellow color. Genes that express yellow color increase more the frogs´ fitness than genes that code for the other colors. So natural selection increases the frequency of genes coding for yellow color and will decrease the frequency of the other alleles. Probably the less favored will be genes that express blue.

Everyone loves his hometown or city dearly. It is like loving the home or the place where one passes one’s life. My town is close to a canal that flows out of the river some eight kilometers away. Gardens and parks surround it on all sides. Beautiful flowers and tasty fruits of all the seasons are to be found welcoming you as you approach the town. Grassy grounds border the town where children, men, and women are found playing in the afternoon.

Gardens and parks surround it on all sides. Beautiful flowers and tasty fruits of all the seasons are to be found welcoming you as you approach the town. Grassy grounds border the town where children, men, and women are found playing in the afternoon.
The town has two colleges, one for boys and another for girls. It also has four high schools and six middle schools. The students are mostly from middle-class or rich families, but now some working-class people like laborers have started sending their children to schools. We have quite high standards of education as we have in some famous colleges and schools in the big cities. The reason is the hard work that teachers put in and the interest that most of the students take in studies.
The town has a fine public hospital where most government doctors attend to patients as well as they can the public dislikes the few careless doctors. They are often transferred on the public complaint. Of course, the hospital is often overcrowded and suitable medicines are in short supply. The richer people go to private clinics where they get medical treatment of their choice.
The town municipal committee keeps the town clean, but sometimes garbage heaps collect, and the whole place begins stinking (giving an unpleasant smell). The electricity department takes care that the streets are brightly lit at night. When people have complaints about its working, it begins performing better. The police and other government departments in the town, on the whole, have been performing their duties equally well. The people of the town have now started complaining of rising corruption in government offices. It is time we checked it with most strictly. When I am away from my town, I feel as if I am away from something dearest in life.

The fetus develops toenails, lips, and eyelashes and The fetus begins rhythmic breathing movements changes takes place during the first trimester of a woman's pregnancy. Thus the correct option is B and D.
What is pregnancy?
Pregnancy is the period in which a fetus develops inside a woman's womb or uterus. Pregnancy usually lasts about 40 weeks, or just over 9 months, as measured from the last menstrual period to delivery. Health care providers refer to three segments of pregnancy is called trimesters.
The baby's brain and spinal cord will develop from the neural tube. The heart and other organs also are starting to form. Structures necessary to the formation of the eyes and ears develop. Small buds appear that will soon become arms.

Describe why certain traits increase in frequency in a population. Provide ONE example to support your response.
Answer:
When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
Explanation:
Because of having dominant traits certain traits increase in frequency in a population because they have.
What are traits?A phenotypic trait is a specific variant of an organism's observable characteristics. Phenotype refers to any measurable, observable and obvious characteristics of an organism. It can be either hereditary or environmental, but usually occurs as a collection of both.
When any allele tends to determine the phenotype, when passed from parent to child, it called as dominant allele. In case of homzygosity as well as heterozygosity, dominant allele can express itself.
Recessive in contrast is, when genotype is homozygous, the trait expressed is referred to as recessive trait. Therefore, certain traits increase in frequency in a population.
