Explanation:
Which of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?
A : Nutrients are absorbed into the blood from the intestines.
B : Lungs expand and contract through movements of the diaphragm.
C : New red blood cells are generated in the marrow of bones.
D : Gases exchanged in the lungs are carried by the blood.
Answer:
D
Explanation:
Your first order of business should always be to see which answers involve both of the systems. A has the circulatory system (blood) but no respiratory system (intestines are the gastrointestinal system), B has the respiratory system (the lungs) but no circulatory system, C has the circulatory system (new red blood cells) but not the respiratory system (bones are the skeleton), and that just leaves D, so it has to be the answer. When you look at it to check, it includes both systems, as the lungs are part of the respiratory system and the blood is part of the circulatory system.

How was bipedal locomotion important to hominin evolution?
Answer:
Bipedalism freed the hands so they could be used to cart food, make and use weapons and other advantages of freed hands. Bipedalism is a much more efficient way to walk and run and this fact is quantified. Bipedalism raised the early proto-human above the horizontal so he could see predators approaching. Bipedalism is a much more efficient design to cool down overheating bodies.

Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.
What is a tundra?The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.
Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.
Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.

Skin color, fur color, and height are examples of which inheritance pattern?
A. Mendelian inheritance
B. incomplete dominance
C. codominance
D. polygenic inheritance
Answer:
D
Explanation:
Skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.
What is polygenic inheritance?Polygenic inheritance is defined as a type of heredity where the trait is created by the interactions of many genes, as opposed to monogenic inheritance where the phenotype is created by the expression of just one gene.
When numerous separate genes have an additive or comparable effect on a single quantitative characteristic, this is known as polygenic inheritance.
Multiple gene or multiple factor inheritance are other names for polygenic inheritance.
The some of the characteristics are since epistasis is not at play, the expression of one gene is not obscured by the existence of the other genes. There are no dominant or veiled genes; the gene involved in polygenic inheritance is either contributing or non-contributing.
Thus, skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

Is someone walking up to you from behind? A friend is walking up to you from behind. What three observations would help you predict when they would reach you?
Answer:
Three things i will observe are :
The sound of their movement when approaching meThe frequency of their foot stepThe distance they are away from meExplanation:
In my opinion, the three points highlighted above can go a long way to help predict how soon or when they would reach meThe sound of their foot steps will determine how far or close they are from from me, if the sound is loud they are closest, if it is low then they are at a distance father.The frequency of their foot steps tell me about the speed with which they are approaching me, if the frequency is high, then they will approach sooner and vice versaThe distance they are way from me can help estimate when they would reach me, though still dependent on items one and two above.Why did the population of deer increase during the wolves absence?

Answer:
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes
Explanation:
Genes are made of DNA, but there are many (numerous) genes found along chromosomes. Only a small portion of the chromosome will be radiolabeled.
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.
What is the relationship among DNA a gene and a chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.
Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Crossing-over can happen at any location on homologous chromosomes. The farther apart two genes are, the more likely that crossing-over would separate them.
On these chromosomes, which pair of genes would be most likely to be separated by crossing-over: A and B, or A and C? Why?
Answer:
The answer is C I believe. Chromosomes usually make a pattern and thats the points were it would make a pattern.
~Paige~Crossing-over chromosomes.
The crossing of the chromosomes is the swap or the exchange of genetic materials. It takes place in the germline, at the formation of the egg. This is also called meiosis. It aligns with DNA sequencing. The pried chromosomes cross over the other.
Thus the answer is they make a pattern that points in the pattern.
This shows the crossing happens at the homologous chromosome. The farthest apart two genes the most likely they cross each other that would separate them. Thus the option C is correct. They cross at the end., hence is a process called recombination.Learn more about the chromosomes.

What would happen if the distance of a planet from the Sun was doubled?
Answer:
Hey! Here are your answers!
1) The Earth would make a double orbit * in terms of time duration of 365.25 days * meaning there'd be about 730.5 days in a year ( a leap year therefore would be every 2 YEARS )
2) Because SOLAR RADIATION (light and heat) takes about 8 mins to reach Earth, this would be double to 16 mins
3) The planet as a whole would cool down significantly to the extent that life cannot exist!
Explanation:
HOPE THIS HELPS!!
According to Kepler's third law, T2 R3, the cube of the mean distance between the planet and the Sun (R) and the square of the time period (T) are exactly related. As a result, the planet's orbital period lengthens by a factor of two.
How does the distance of a planet from the Sun affect it?The orbital period increases and the gravitational pull decreases with a doubled distance from the sun. Depending on how far away from the Sun a planet is, it will have a different orbital speed.
A planet moves more quickly and experiences a stronger gravitational attraction as it gets nearer to the Sun.
It moves in its orbit more slowly the further it is from the Sun because of the Sun's weaker gravitational attraction.
Therefore, the planet's orbital period lengthens by a factor of two.
