How do the circulatory and respiratory systems deliver important
substances?
Answers
Answer:
Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.
The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color? *
A. Only the interaction between dominant genes.
B. Only the interaction between recessive genes.
C. The interaction between dominant and recessive genes.
D. The interaction between dominant and recessive genes does not determine inherited traits.
Answers
Answer:
c is right answer.
The interaction between dominant and recessive genes
Explanation:
Eye colour and blood groups are both examples of dominant/recessive gene relationships.
Eye colour
The allele for brown eyes (B) is dominant over the allele for blue eyes (b). So, if you have one allele for brown eyes and one allele for blue eyes (Bb), your eyes will be brown. (This is also the case if you have two alleles for brown eyes, BB.) However, if both alleles are for the recessive trait (in this case, blue eyes, bb) you will inherit blue eyes.
Why forest and wild life are closely related
Answers

A. Polar
B. Tropical
C. Temperate
Answers
The climate zone which receives the lowest insulation is the Polar climate. Thus, the correct option is A.
What is Polar zone?A polar climate is a place where the climate generally has a temperature range below freezing temperature, icy, and covered in snow from all the areas. These areas do not get any direct heat and sunlight from the sun. Polar climates are usually located at the North Pole of the Arctic, and at the South Pole on the continent of Antarctica.
The polar regions which are surrounding the Earth's North and South Poles belong to polar. The areas around the North Pole is called as the Arctic region. The area around the South Pole is called as the Antarctica region. These regions have a unique set of climates.
Therefore, the correct option is A.

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answers
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.

Which mechanism explains how both A and B antigens produce type AB blood?
Answers
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2).
Answers
Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.

Pea plant has Round Seed dominant over Wrinkled Seed.
Round Seed allele is R
Wrinkled Seed allele is p
_____________________________________CONDITIONS:Hom.ozygous Dominant Alleles: RR (Round Seed)
Heter.ozygous Dominant Alleles: Rr (Round Seed)
Hom.ozygous Recessive Alleles: rr (Wrinkled Seed)
_____________________________________CROSS I:Whenever we cross Heter.ozygous Dominant(Rr) with Hom.ozygous recessive (rr), we get 50% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,
The P1 is Rr
The P2 is rr
When we cross them,
It has 4 offsprings,
Rr Round Seed
Rr Round Seed
rr Wrinkled Seed
rr Wrinkled Seed
Thus the answer is 50% round seed as there are 2 out of 4 heter.ozygous dominant round seed.
_____________________________________ CROSS II:Whenever we cross Hete.rozygous Dominant(Rr) with another Heter.ozygous Dominant (Rr), we get 75% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P2 is Rr
When we cross them,
It has 4 offsprings,
RR Round Seed
Rr Round Seed
