Answer:
The correct answer would be -
50% heterozygous red flies and 50% recessive brown eyes flies in offspring
Explanation:
This is given that a species of fly has two traits for the eye red eye which is the dominant trait and can be represented by R and the brown eyes trait which is recessive and represented by r.
Given: heterozygous fly which means have both traits gene but as Red is dominant it will have red eyes mates with recessive brown eye fly.
Rr × rr
gametes: R, r and r, r
then,
R r
r Rr rr
r Rr rr
There is 50 % recessive brown eyes flies in offspring and 50% heterozygous red eys offspring.

A man with homzy type A blood and a woman with heterozygous type B blood want to know the probability of having a child with type AB blood.
Answer:
[tex]\frac{1}{2}[/tex]
Explanation:
Homzy. type A blood = AA
Heterozygous type B blood = Bb
Punnett square
| B | b
A | AB | Ab
A | AB | Ab
The ratio is = 2:2 = 1 : 1
The total number of outcomes are 4
The number of AB are 2
Thus the probability is [tex]\frac{2}{4} = \frac{1}{2}[/tex]

Answer:
What's your question?
Explanation:
Use the following terms: Natural Selection, Variation, Mutation, Adaptation, Overproduction, Descent with Modification, Evolution, Population, Species, Heritability, and Fitness and show the relationship between them that lead to the result, Evolution.
Answer:
Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.

Which of these statements is true about internal respiration?
[a] Production of ATP
[b] Exchange of gases between the bloodstream and tissue cells
[c] Exchange of gases between alveoli and the bloodstream
[d] Breathing between the atmosphere and the alveoli
Answer:
c
Explanation:
because I don't know how to exam tho
Exchange of gases between alveoli and the bloodstream ( Option C )
Internal respiration is the process of exchanging gases ( i.e. carbon dioxide and oxygen ) between the bloodstream and the alveoli of an organism. as seen in human.
Internal respiration ( exchange of gases) occurs between Alveoli and the bloodstream. While External respiration occurs between the atmosphere and the alveoli.Also the Alveoli is important in both external and internal respiration. but for internal respiration, the alveoli exchanges gases with the bloodstream before it is passed to the internal issues .
Hence we can conclude that the true statement about internal respiration is ; Exchange of gases between the alveoli and the bloodstream.

Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities.

All of the following can take material into cells except
O active transport
O exocytosis
O endocytosis
O passive transport
Answer:
The correct answer is - exocytosis.
Explanation:
All of the given options of the transport mechanism are the transport of the substances either into the cell or out of the cell or both. Active transport is the transport mechanism that involves the transports of substances from the lower concentration region to the higher concentration region and utilize energy.
Endocytosis and exocytosis are the forms of active transport, however, endocytosis involves taking material into the cell and exocytosis out of the cell. Exocytosis is the form of active transport as it requires energy to moving materials from within a cell to the exterior of the cell.
