Facilitated diffusion is a type of passive transport in which ions and molecules pass through a semipermeable membrane as the permeates present on the membrane facilitate transport, similar to simple diffusion. Facilitated diffusion requires no metabolic energy and occurs simply across a concentration gradient

How can I find out where we have similar characteristics from our parents or grandparents❓?
Step-by-step answer
PAnswered by Dr
Answer:
You share about a quarter of your DNA with each of your grandparents.
Pieces of DNA are not passed down equally from each of the four grandparents. However, they make up a relatively small part of the total DNA. These exceptions have little impact on the total.
explanation:
Your body is made up of cells that contain your DNA, or genetic information. DNA tells your body how to grow and function, and that's what makes you who you are. Chromosomes are long pieces of DNA that are organized in our cells.
We have a total of 46 chromosomes, 23 of which are pairs. Your mother gives you one chromosome of each pair and your father gives you the other! That means each parent contributes exactly half of your DNA.
There are 22 pairs of chromosomes that are identical in males and females. Autosomes are the strands of DNA that make up the human body. The sex chromosomes are the final pair that decides whether you are female (two X chromosomes) or male (two Y chromosomes) (X chromosome and Y chromosome).
On the other hand, your parents have an equal mix of DNA from both parents. Turns out it's a little more complicated than that.
While every grandfathercontributes 25%Their DNA, the exact percentage we get from our grandparents, is determined by chance.

Describe the role of microtubules in mitosis. Why must microtubules both assemble and disassemble for mitosis to proceed properly?
Step-by-step answer
PAnswered by Dr 1
Microtubules help chromosomes divide during metaphase (and then anaphase).
Both fold and unfold, allowing the chromosomes to reach opposite poles in telophase

What immediate effect would the amount of radiant energy hitting part of the earth at that point have?
Step-by-step answer
PAnswered by Dr
Answer: It begins to heat the surface it hits and bounce off or redistribute the energy.
radiant energy:
Radiant energy is the energy carried by electromagnetic radiation such as light, X-rays, gamma rays, and thermal radiation, and can be defined in terms of discrete photons or continuous electromagnetic waves.
Explanation:
When electromagnetic waves are absorbed by an object, their energy is converted into heat (or electricity in the case of a photoelectric material). This is a well-known effect, since sunlight heats the surfaces it shines on.
Although infrared radiation is often associated with this process, any type of electromagnetic radiation heats the object that receives it. When electromagnetic waves are reflected or scattered, their energy is redirected or redistributed.

Huntington's disease is a dominant allelic disease. Reviewing his family tree, Parker found that 64 out of 100 relatives were affected by the disease. What is the value of q? What is the value of 2pq? How many people dominate Parker's family tree? How many people are heterozygous in Parker's family tree?
Step-by-step answer
PAnswered by Dr 3
Answer:
a) Wert q=60 %
b) Wert 2pq=0
c) dominant individuals in Parker's family tree =64
d) the number of heterozygotes in the Parker family tree = 0
Explanation :
p2 + 2pq + q2 = 1Ip + q = 1
p = dominant allele frequency in the population
q = frequency of the recessive allele in the population
p2 = percentage of homozygous dominant individuals
q2 = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals

If 2500 kcal were reduced to 250 kcal instead of producers, how do you think that would affect the population of all consumers? Would the ecosystem still be able to support (conserve, conserve) large numbers of hawks? Explain why or why not
Step-by-step answer
PAnswered by Dr 1
This would affect the consumer population as the producer will decline. The number of consumers will increase and the ecosystem will not be able to support a large number of hawks since the 10 percent rule applies.
